I have a 2004 & 2008 GMC Envoy 5.3 ltr. This video is so DEAD ON TARGET with the issues. So far currently 147, 000 mile range but also near the 15-20 year mark on my Envoys these issues have arose already. The front hub assembly’s BOTH the sensors and the alternator. But if it hadn’t been for this video I’d of never known about the sensor with the steering position. That’s my issue in my 04 currently. The other is my ABS light in both envoys. Wish I could figure out that one. Thank you 1A Auto for your videos and you GREAT PRICES , Parts and Customer service . Most of all your time in making these videos because you put repairs in a simple and easy to understand laymen terms for us DIY mechanic’s.

I have used you guys in the past and I'm always pleased with how awesome you guys are with customer service and knowledge.

170,000 on my 2004 4.2 and 246,000 on my 2006 5.3l trailblazer. THESE THINGS ARE BEASTS

I've had my '05 since new. In 144,000 miles, I've done brake pads (still on original rotors but got custom made braided hoses), suspension bushings (ball joints and struts/shocks on the rear while I'm at it), spark plugs (ignition coil boots, oxygen sensors and injectors cleaned on ASNU machine with new Viton seals and stainless basket filters since I'm in there) a radiator and a water pump. Electronics wise, I've replaced the rear CHMSL but that's been it. I've also been on top of all oil and fluid changes every 25,000 miles (engine oil by the OLM). This has been a pretty reliable vehicle as far as I'm concerned, even with the dreaded 4L60E that I've run nothing but TES-295 in since day one.

Great video , actually all your videos are very informative and help me through issues on my GMC which I love, but these newer cars ,they keep you on your toes if you are an oldster and your videos are great help.Keep up the good work.

Thank-you from Yukon, Canada, love your site... , and will order my parts from you guys, cause you took the time too do such video's :)

Thank you. Going to look at an 06 today with only 170k and CLEAN here in the Midwest. This quick list will be very helpful!

My 2007 Envoy with about 120K miles. The ignition switch caused fan speed/vent flow control failure among other minor losses as I recall.

I found this video very informative. Because I own a 2005 GMC Envoy. And drive it on a regular bases 👍🏾👍🏾

U people are just the best. Thanks for continously informing us

219k on 2004 4.2. Runs great. Only big repairs were water pump blew and gear shift cable snapped at 218k.

Thank You, Kindly. Great Video. 👍👍

Thanks for your video, blessings

subsscribed. I have a 2005 GMC Envoy at 120k miles. He's getting up there, his name is Charles. I'm hoping to maintain this vehicle and get many more miles out of him.. Thank you for this video. Looking forward to checking out the other one and getting some parts down the road. Literally... L.O.L.

One thing I didn't see was the factory power steering cooler. I am up in Canada and have owned 3, 2 Envoy 4.2L and 1 Saab 6.0L, and all three had the same part rusted out about the same age (6 years old) even with annual rust protection oil spray. Out of the blue the power steering pump will make noise and when you check it there is no fluid. New replacements are much better quality and thankfully have never needed replacement again. I still have 1 Envoy and know where the 2004 is, both running great with 250K + , my 2006 besides brakes and tires has pretty much original everything under the hood, except Power steering cooler, power steering lines and 3 sets of wheel bearings, 1 due to stabilitrac errors and I did have a weird one where the truck would stall every time you put on the left turn signal. A bad ground connection on the firewall caused this by the fuel pump and turning signal shared the same one. The other 4 issues you mention have not been a problem yet... I am likely on borrowed time but this truck has been amazing and very reliable really.

Thank you, good information.

No one mentioned the rear air suspension going out and how expensive it is. They actually sell the kits to switch your air shocks to springs

The predecessor to the Acadia. My Acadia was 8 years old and the only thing that stopped it was hurricane Ian. I miss that SUV.

275,000 on my 2006 Envoy. It’s not in great shape , but it still runs good ! What I’m dealing with now is the ignition getting stuck in the middle when I turn off the key…

I have 2 other issues. 1 when the water pump starts to go bad. The fan starts to wiggle and eats the shroud. 2. The backing plates rust out way too early. This holds your parking break brackets.

I have a '05 Envoy SLT since 2006, got it at 19k miles and now has 166k. The video on the window regulator was very helpful and I ordered the part from your company. This Envoy has several problems but I want to fix it up. My kids grew up with this car and I don't want to give up on it. Problems: stalling/hesitation, speedometer and fuel gauges out, A/C intermittent, radio static, and needs a body panel replaced or repaired. Just replaced a window regulator and already had to replace the little plastic connectors on each end of the transmission shift selector cable. It's had not one but TWO water pumps replaced and had to get towed each time. But that was years ago. I want it to keep going!

I have an 08 Envoy SLT, the Ignition issue is for every envoy, even the GMC Jimmy's. The other issues that envoys have is they tend to get electrical shorts. They also get secondary intake issues and evap leak issues.

I found it informative.

Thinking about buying a 05 Denali envoy with about 145k mi for about $5k for a point A to B car. Think it would be a decent deal?

Thank you for the video. I have a 2002 gmc envoy slt 4 wd

Had my '08 for Twelve years, daily driver to Work for nine of those, and NEVER HEARD of any of these! Five Cross-USA trips too!

I think you just helped me fingers crossed I'm gonna get a buddy go over this video and my car cheers and thanks

There is a significantly large yet unrecognized gmt360 (TB,Envoy) following. We need more of this lol

Thx for the info! I’m thinking of getting a 2002 fully loaded forest green with brown interior to camp and hike here in WA state.

👌 Best video by far for my GMC Envoy 07. Every-single-one you mentioned I had fixed or I'm currently fixing again. I swear I have watched soooo many KZfaq videos about this car I feel as if I specialize in Envoys. Anyways... Can you do a video on on the Throttle sensor unit? This seems to be a big problem for us envoy drivers. That and the door actuator needing replacement due to the air and heat not coming from the front facing vents. And recalls on this car.... SO many recalls. One due to the driver door getting too hot and fires have been reported in the past. My door gets real hot itself even after I brought it in for one of the many recalls. But... I definitely need a video on how to clean the throttle and/or replace. That's my current reading on my check engine light. I also carry my jump box with me because my car won't start probably 3x a week. Ugh.

Really well explained. Thanks!

The more you talked the more positive my opinion of you guys became, comments solidified my decision to subscribe,and I don't take things of this matter lighty,Thanx Carl

Your videos are very helpful! Can you please do one on how to replace a mode actuator on a 2006 Envoy Denali? I have air coming out of the floor and defrost vents, but not the front vents. I have located the non-working mode actuator, but I cannot figure out how to get it out to replace it.

I have a 2006 GMC envoy slt. I have 215,000+ miles on it. I love mine. I put some work into it but I'm content with it. This vehicle helped me a lot. It was well appreciated. Keep it up.👍🙂

Thank you

Thank you very much.

My truck is back! Right on. Would you consider doing a video on replacing the push button for the rear glass release? Hoping you also sell that part. Thank you! Love your videos.

Very good video,,,👍

I own one with 137,000 mile I bought it with 93,000. I have had to replace all wheel bearings. I am currently have to replace bearings in the front differential. I still like the vehicle. Michelin tires work best for me.

My mother had one. Absolutely best family car ever

Could you plz tell me what fuse operates the license plate lights on an 2005 GMC Envoy??? Plz, I've been looking at my book & I can't seem to find it, I need help.

Do u have video of changing out transmission to 05 gmc envoy

Do u know how to take out the pistons without pulling out the engine from a 4x4 version

2007 envoy 110k miles.. Let me start with i love this car. Ive owned several diff cars and it runs great. I have also replaced the ignition switch 3 times in the 8 years owning it. May have to do it a 4th..its a pain.. But i love this car and for something that runs great.. Safe in missouri winters and paid off ill take it as a small annoyance.

I've got an 05. The ignition key won't turn all the way back to come out. And the headlights on turn on on hi beam. Any thoughts on what's wrong?

I have a 07 envoy was wondering if I would be ok pulling my 20ft bass boat like pull it in and taking it out of the water???

I highly recommend 1A Auto their customer service is top notch and their parts are adequate to oem specs. My opinion from shopping with them.

Great vid on a pretty great (but not perfect) vehicle. I have an 03 Envoy XL SLT with the excellent 5.3 V8. 245k miles, gobs of power with my 4.10 axle option, and relatively good mileage for a heavy V8 beast. Have had ignition key issues (wouldn't shut ignition off and release the key), Front wheelhub bearings, and replaced most of the worn out steering/suspension. There's also a battery draw, could possibly be stereo/alarm system (I just pulled fuse), OnStar system (pulled fuse), short in driver side door (nothing electrical in door works except power locks, sometimes seat heaters come on randomly), and likely frayed/grounded wires in the troublesome XL hatchback. 4X4 isn't working, and there's a loud knocking under dash related to Automatic Climate control upon starting vehic. Other than buying someone else's electrical gremlins and uninspiring soccermom-mobile handling, I love it, particularly the modified LS engine.

Dear 1A Auto, I have gmc envoy 2007 when I tern steering while drive sloly I feel the car like jumping on humbs. I went under the car I fond cracks on the rubber of the both racks and there is a red oil on the gear case. Can you plz tell what the problem is and how to solve it. Thx

About to get a 2004 GMC Envoy like this one with 5.3L V8...Do You carry the New starters for it? If Not, what Part # do I need? I can only find the V6 ones. Thanks !

Check the frame under the drivers seat, ours was rusted o the point I could put my finger through the frame. Was and had been a great vehicle..

You forgot the Trans Shift Cable Bushing #6

This car seems pretty reliable i just got an 04 v6 hope everything goes good lol

Sup wit da pwr steering inlet from the resistor to the pump

I need info on where is the heater core located ???

My 2005 gmc envoy 110,000 had a missfire I bought 6new spark plugs started running a little better except the coils were bad so I went to go buy 2 coils as I was changing them with the car on the car turned off. Had to have the car towed and now it’s cranking but won’t start. Anybody have any idea?

My 2002 4.2 has 251k miles and i finally had to put an alternator in it two weeks ago and a water pump this week. Other than wear items I've never put a dollar into mine in years.

The actual problem that ate my head was the *gearbox*. Renewed it twice, again the next year it will end up with transmission issues that need another renewal. Fixed it and sold it.

I'm getting oil in the (?) intake breather box (?) on a 2004 gmc envoy. Any suggestions? Doesn't seem to have a pcv at all.

Man some of the problems you guys are naming I've never ever dreamt of in my Envoy! Heating door issue what the heck is that??Over 276,000 miles & still running strong, except a cam position sensor code and upper intake gasket leak other than that she's great! I have a 2003 Envoy XLT with the 4.2ltr inline 6 with all the bells & whistles except sunroof! I love this thing and wish GM would bring it back with modern styling better interior materials and better gas mileage! I'm about to purchase a 2005 Denali XLT AWD for $300 needs engine and transmission but the body and interior are in great great condition compared to mine! I have a personal mechanic that can do the work very reasonable for me but I'm wondering about the reliability of the 5.3v8 heard they have lifter issues due to the cylinder deactivation process GM used. Is this a good buy for $300 also I can get the motor & trans for a discount because of my mechanic!!

I own a 2004 gmc envoy and there's something draining the battery I love this car I hope there's light at the end of the tunnel I want car back

I have 2008 envoy, the rear defrost, not working check fuse 1 st? I didn’t see a rear defrost fuse listed is it called something else?

Do you know how to fix a sunroof for it on gmc envoy 2005

My correlation code was the cam position sensor not a leaking actuator or loose harmonic balancer

Where do I find the EBCM on a 2007 gmc envoy.

I have an 06 GMC Envoy XL 4.2L and when it is cold out it dies meaning when I turn it over it starts but then dies if you leave it for a couple minutes and try again it is fine but it only does it when it's cold. Any ideas?

I've noticed that the better the quality control in the build of a vehicle, then they all have the same issues when something breaks.

I have asked so many on these videos about a problem I'm having with my 2002 envoy and can't get a direct answer to my question maybe it's because no one has had the same exact problem. But I'm trying one more time. My 2002 Envoy has a little over 200,000 on it and until February of this year it has a been a great vehicle. But one day I was driving down the road at 55 mph and all of a sudden it was like I had no gas. At first it sputtered like it was running out but the gas needle said it had 1/4 tank and I knew it was not out. But I pulled over and sat there for about 10 minutes and turned the key and it cranked up instantly. I drive it about 5 miles and it happened again and I pulled over and shut it off. It would coast idle for several miles but when I pushed the pedal it got no gas. This happened 4 times until I made it home. The check engine light never came on. The next time I drove it was after the fuel filter had been replaced. It did the same thing after I drove it for 5 to 10 miles. The last time it was test driven the check engine light did come on and it said shut engine off. This had never happened before. My mechanic friend came and picked up and had it for a few weeks. The next time we test drove it it went further before it happened. It went 25 miles and this time it coasted for a mile and when the gas pedal was pushed it picked back up and it was driven another mile to his house. It has had several diagnostic tools hooked up to it but it doesn't show any codes. I replaced the battery as well as the fuel filter. But we don't know what else to do without taking it to a shop that has access to gm diagnostic app. I've seen so many videos and stories where people were advised by mechanics to replace fuel pump and after they spent a thousand dollars doing that they found out it was not the problem and instead was a sensor or some other less expensive part. Does anyone know anything about this or what it might be?

My new ignition lock cylinder will only go half way in. What am I doing wrong?

Can some head me in the right direction i have a 2006 envoy denali and the stabilize track is on my dash and i cant seem to figure it out .

I have my drivers side headlight high and low beam go out hit the headlight a couple times and it comes back on. Any ideas?

2003 Chevy Envoy and I looked my keys n it, and battery dead so is there any other way to open it. And it doesn't have remote control either

Been having problems with my 2005 GMC Envoy XUV sle, it has 394,000 miles and still runs strong... amazing vehicle. The problem I've been having lately, is an occasional dead battery and all the gouges drop to zero and the battery warning light comes on. After a minute or so, sometime less, all the guages return to operating normal. Checked the battery, alternator, and even added an extra ground wire from the motor to the body. Recently, I was told that it could be the ignition switch. Has anyone else encountered this problem?

Themostat was the first to play out when he got the truck . He gotten it fix bout a month ago and now it saying the cooling fan sensor going bad . The engine light came on after we use the air in the truck .

My 2005 Envoy/Denali won't release the key when you turn it off. How do I remove the console/side panel so that I can check the switch to make sure it's pushed all the way in underneath the shifter?

Don’t forget the dreaded front differential leak on the 4 wheel drive envoys and trailblazers. They leak like crazy

My envoy has 225,000 miles, suspension needs rebuilt but engine itself is perfect! Not a lick ot dirt on throttle body, still gets advertised mpg or better 20 years later

i have p0340 camshaft position sensor circuit , can you tell me what is that?

I have a 2006 gmc envoy Denali 5.3 v8 4x4 and I can’t find out what transmission is in it not sure if it’s a 4L60E 4L65E 4L80E???? I cant get under it to see it! Is there any other way??? Please help!😩

I have a 2005 GMC envoy 4.2 that is having an issue with cylinder 6. It keeps saying it's a misfire. Well we put a new coil pack in there and put a brand new plug in it and it's still showing a misfire. Any clues please reply back

#6 power steering pump

My 2006 GMC envoy denali rear access chime is constantly dinging. How do I disable it? The doors are all shut.

Do you guys have a video to show how to take the dash apart? I think the fan to my air conditioner is caught on something, it clicks when I turn it off, or when I set it on any setting but the one that blows directly into the cab of the vehicle.

Just had 2 out of the 5 replaced last wk

I have a 2004 Envoy I have only had it about 6 months. 147,000 miles. My transmission slips from 1 to 2 and 2 to 3 but only when I drive it longer distances. It doesn't do it driving around town? I wouldn't think the transmission wouldn't go out with lower miles. ? Any ideas?

They should add a disclaimer, the first 2 items only apply to the 4.2 I6 engine, they don't apply to the 5.3 V8. #3 only applies to vehicles that have traction control systems, and equipped, which was a 2005-09 thing only. The last 2 items apply to all years and models. I would only add the 5.3 V8 AFM/DOD systems are problematic, and only apply to the 2005-09 model years.

You forgot the cracked exhaust manifold issue the ac condenser drips right on it if the tube isnt on or the shield isn't on the manifold allowing water to splash up at it and the insterment clusters go funky 4x4 actuator like to bust apart without warning and the fuel filter being in the tank! Big issue i own a 05 and the sending unit was from the xl

The next time my thermostat goes bad in my Envoy, I'm gonna take the guts out of it, reinstall the housing, bypassing it, then I'll install an inline thermostat down where the lower hose goes into the radiator. They unscrews easy and use standard thermostats , so you can pop out the thermostat when you flush your coolant without impediment to the water flow.

Key ignition done that too put a new one in couple years ago

You have any mechanic suggestions in ohio I can take my suv?

question: I have a 2006 GMC envoy SLT (3rd row seating) and the check engine light is on, I think it came on because of a damaged gas cap, is that possible?

What about abs light and traction control light on?

Ignition switch on my envoy caused "reduced engine power " and gave a code pointing to the throttle body. Wasn't the throttle body, it was the ignition switch getting or not reading the correct voltage.

Bruh I have a 2003 Envoy SLE with 254k miles, the only one of these issues I've ever had was the heating one, the thermostat is alright. The groaning noise actually happened once, but if you get your tires realigned it usually goes away.

I replaced my ignition switch myself after countless efforts to figure out what was wrong (replaced alternator battery etc thought it was a wiring issue) eventually got to ignition switch and when I took the old ignition switch off which was clearly the one that the manufacturer had put in the car because of the way it was zip tied into all of the other elements when I took it out I noticed that one of the metal prongs that was supposed to be inserted into the switch or whatever was completely bent down flush so it had never been completely plugged in or connected in general and it was just probably catching friction which was pretty frustrating because it was a big issue I had for a long time and I couldn't figure out what it was and to know that it was from the freaking manufacturers installing it incorrectly was pretty I can't even think of a word dumb basically lol

What to think about that

No issues with any of those 2009 however, your 4200 exhaust manifold is a ticking time bomb if you didnt get the service bulletin.

Stale ? I’m what way rn I’m Jacinta problem where when I drive the car wants to accelerate more but doesn’t and the speedometer goes up and down and just revs constantly if I don’t put more gas on the accelerator

Mine has 250,000 miles the only major thing I've noticed is sometimes the car won't until I lift the hood and slam it and then it does. Does anyone know what that may be because the battery and alternator is good
