Today I sit in a Hotel, in Pennsylvania. I came off the highway to fuel up and the dash panel told me to service it and my brakes sound springy, pulsing like ABS. So it is Sunday, mechanics are closed and I sit here. I was 7 hours into a 13hour trip. I am glad it happened off the highway. I do like my Acadia, it has been dependable running up and down the East Coast of the US. It pulls hills great and it good on gas. I just hope the mechanics do not try to fleece me, now that I have an idea what is wrong. Gotta love youtube, you can learn about anything here. I learned it shouldn't cost a lot to fix.

Definitely know what you mean about sluggish... Driving on the e-brake will give some resistance. 😂

Change the abs module and yes it is the mass air flow sensor as well it’s not the purge canister it the one over top of gas tank. Then reset the ecu by taking both cables off connect them together for 60 mins then place back on battery. Then change the back pvc vale on backside of the throttle body. Do all before you reset ecu then calibrate gas pedal by turning which on yet don’t crank mash gas pedal to the floor very slowly and let come back up slowly repeat 5 times.

I use a bottle of CataClean and added to Premium gas on a 1/4 tank. Ran it hard and the 02 sensor error was remove.

The mass air flow can be cleaned and the smell could be a 02 sensor.

I have an 09 Acadia with about the same lights come on and when driveing it kind of feels like I’m slipping on snow and some feeling of grinding in the break pedal when trying to stop.

PCV Valve might be stuck open, allowing the oil to be sucked into the Air tube.

I honestly think all the workers at the GMC plant where my Acadia was assembled was on hard drugs 😲💰🍋

I have a GMC, I turned on the ABS and there was noise in the brake pedal. I don't know what the problem is. Can you help me?

Well...like many others I also have the same issues. Although this video is 8 mos. old - I do not see any updates. On my 2011 GMC Denali AWD (after thorough internet research) I have concluded that, AWD OFF, stablitrack OFF, parking brake ON (when it is not), ABS warning light ON, and NO cruise control - is the BCM is bad. I just got the new one in and tring to find a repair shop to program/flash it in. Will let ya know!

My 2011 Acadia SLT-1 has 174k miles. I love it and gets me where I need to go! Only problems I’ve had with the Acadia, me being the third owner is a fuel injector replacement, and engine belt. What I can’t stand about the Acadia is the gas mileage bring around 14.4 driving city/highway daily. Finally I can’t stand the headlights, I’ve had them buffed and had led lights installed and I feel I can’t see even with led fog lights.

Replace your brake sensor under the petal. Easy fix. And cheap. Also I believe the oil issue is a “pcv” valve I believe it’s called. I have exact same issues.

There’s a Vapor Canister Purge Solenoid, and when that goes out it the engine starts making a loud ticking noise . Just like in the video

That reservoir on the side of the air duct is for intake sound tuning, a resonator of sorts. Nothing on that duct is a drain or oil catch.

Hey @bradzbulidz I appreciate your video I also have the same car its a 2011. My problem with her is that the ABS came on with the dash reading Service ABS / Stabilitrack System. With this problem going it caused the vehicle to drive under 60 mph like picking up speed almost like the transmission went out. Thats how weird it was driving. Thanks for sharing what problems u have with your vehicle. But if I was u I'll get that mass sensor

Anytime you change the rear brakes on an Acardia you have to have a dealership level OBD2 Bidirectional Scan Tool to reset/recalibrate your ABS/Brake System

My 2015 Acadia SLT awd did this and it was abs, traction control and at high speeds it would buck/shake and lose power. My fix was rear new wheel bearing and new abs wire. I also did the brake sensor first it didn't work.. Seriously... Put a abs code reader on it see which one is going bad. Also I sprayed white lithium grease in all electrical door connectors.. loads of it..lol mine has ran great since..

Change the pvc it gets clogged and want let the crank case breathe so it forces the oil throw the front tube that hooked to the air intake hose that's why you get the oil I had to change it on my daughter's acadia but I seems I can't find why the Stabilitrak and traction control want go off

The stabili track problem can be caused by more than one sensor, may be the oil level or a bad sensor connection. I like GMC but my Acadia is a big pain.

you need to have it better scanned. the small scanners, such as that at autozone will not show codes other than engine codes, such as abs codes. you might have a bad wheel speed sensor, which will throw the C0561 code. you also sound like you have a misfire. the exhaust noise my be your flexpipe, the small one up front (known to fail). but again, you need a more complex scan, particularly with live data. that stability track control notification most likely is not the abs module itself but rather a code you have not pulled with a more complex machine.

Mine has ran great sense 10 when I got mine really no issues till I hit 145,000 but nothing more then things getting old needing replaced.

I have a 2008 gmc acadia and my was doing the same thing my husband is Mechanic and he bought a new computer for 160.00 from auto zone and we had it program at this shop for 230.00 and it's been fine ever since and it's been about 3 years now

check the ground wiring or cam shaft sensors i had some newer chevy vehicles around 2011-2014 got rid of this Stabil track issue mine was the ground from coil pack module runs to engine block and the came shaft sensors issue when away. this car having noise issues everyone's story is different

It say all wheel drive off on my display. I still drive and I wonder will it cause problem eventually? I mean I can't freak turn it on. It has abs on too

Change the air flow censer it could be effective the vacuum advance causing a delay in shifting this the high rpm . also replace the fuse ,it may have a dommino effect on the other sencers

My mom had a 2016 Acadia and she had brake problems transmission problems and all sorts of problems it was so much money that was spent fixing it. If anyone is wanting to buy this car please do your research before buying it and make sure if you buy it used make sure everything is ok with it before buying it. My mom just had to buy a different car because of all of the problems with the Acadia

I have a 2017 buick enclave with the same motor, had the same lights an some codes, changed Sensor on fuel rail, changed both O2 sensors, plugs, cleaned th same areas you did, but with no oil, everything has been fixed or is corrected except i have a slight miss that brings up the check engine light, i am going to change the coil packs next to see 🙈 f that removes the he slight miss, i think you are on the right track will h the converters, I to live on a strict budget but what with all the high pprices for parts now days i have learned to ask others an view goggle which leads me to UTube in which there is alot of info.

Anybody having these issues also check your wheel bearing. The magnet on the back of the bearing can come apart causing erratic signal. It’s an easy check. If you’re ever stranded because of the sensors just unplug all four and you’ll be good until fixed.

StabiliTrak has a sensor on each wheel, sometimes the wire gets corroded from Turning, moisture... You can bandage them so they don't short with Electrical tape.... Temporary fix, the oil is a tad concerning.

My Acadia is doing this now... I have put thousands in mine.. lol new car very soon

My mom's 2011 GMC Acadia does that noise when you start it in the cold

Lol. My 2008 Acadia has all those same lights on dashboard. 😂

Also you never want to clean the throttle body like that. When you open the butterfly up without the key on it messes it up and you will have to have it re learned with a tool. You could possibly ruin it. Its electronic throttle body not cable so cant do that on newer vehicles no more

I had the same problem with my 08 GMC acadia. Threw the parts cannon at it and nothing. Then... I disconnected the brake fluid level sensor and my dashboard Christmas tree went away. Bad sensor:-)

It's the camshaft position sensor.

Change the brake light switch out it control the traction control and your speed sensors

GMC has issue with supply parts in there vehicles ! I had to replace the shift to park then the HVAC then the sensor in the thermostat on a 2019 Acadia 30,000 it’s ridiculous!

Buy Brake position sensor for the GMC Denali

My air flow sensor is 57 AutoZone I just took my part out it was dirty I have the new one

Don’t forget to change you transmission every 6 miles literally 😂

Did you ever figure out why the abs/stabilitrak lights come on? Ever get it fixed??

My 2015 acadia just developed an abs brake pedal feeling and noise but has no dash lights showing ?

They have problem after problem. My stable track is acting up, it says to service it but it won't turn on. It has been running hot, we had to replace the radiator. It leaks puddles of water on the front passenger floorboard. The headlights keep burning out. My AC quit working.

I HATE MY 07 !! List Bought w 60,000 for $10,000 Lasted 3 year before : The WHOLE suspension front and back rebuild ball joints and all $3609 Transmission went $4500 Rack steering mount $1200 Alternator 800 (expected) Starter 500 also expected Now it's doing this shit you have going. I'm just gonna light a match to it !!! The transmission had a recall the fifth wave plate was bad not heat treated right but that was 10 years or 100,000 miles. I bought the car when it was 11 years old of course

Check the power steering pump for a pinhole leak

Change that brake light switch out it controls traffic control and and speed control

We put a new transmission in, fixed that sensor valve twice, replaced rhe front AC pump, replaced the AC line, had to get sensors fixed like twice. Dropped like 3kish into it. It worked fine for 6 months and now the rear AC isnt working and the Stabilitrak shit is back. Im going to either trade it in and get a new truck or take it out to the woods with my son and use it as a practice target.

Check your hub bearing the magnet most likely broke off

Run some chevron gas treatment like 2 jugs and a bit higher octane gas! Cats glogged would also eat gas and foul out your o2s. On mass air if you unplug it and it don’t change the idle Of your car then it’s junk

It was not being mean, but it took 4:30 minutes before you started talking about the problem, but it was a great video 👍

by 2010 they were a lot better from what I've seen, early ones of any model can be a problem

Try the brake switch under the dash on the driver's side

It's your wheel sensor

I have had nothing but problems with my acadia since i bought it. abs/stabilitrak constant issues.... we have fixed everything and it still happens. Wish I never bought it. I have put a lot of money into this truck so... frustrated

My wife bought a 2012 14 days ago. 122k on it. Drove fine first 75 miles. I drive it and I get the codes and it runs like crap. Lol Long story short after going through a 1000 tsb's, reviews, complaints, ect. Yes I think I'm ocd. They all lead back to an unknown issue that no one seems to fix. I found 1 person that stated that they were sitting and then went to go and the check engine light came on stab on off on off service stab and then smoke out the pipe and it would happen from time to time. I said f this and put my foot on brake and gas your not dying on me. I drove it like I stole it all the way home. I get home no codes wtf.... Here's the short of it. After 10 or so turn off and ons I finally get a p0302 misfire detected cylinder 2. The VVT camshaft phasers there are (4) 2 intake 2 exhaust are probably bad. I tore mine down and found that the intake camshaft phaser bank 2 closest to the firewall was bad. I replaced the vvt sensors as well. My intake was full of oil and carbon had to clean that up as well. A catch can is needed on this motor. I can't stress enough no one wants to hear internal but it seems to me that the issues lead back to this. Read up on vvt cam phasers. Also a timing job don't fix this most of the time because no one replaces the phasers. The motor is controlled by the advance and retard of the vvt system. Hope this helps

Had that problem found out what it was. There's air vacuum metal line that needs a plug on the right back of the engine that triggers all the sensors to go crazy I plugged mine no more messages or problems hope that helps anyone

And Transmission, engine and Electrical problems. Biggest Lemon 🍋 ever.

Make sure you clean your pcv system

Just tell us about the trouble with Acadia not your whole life story

O2 etc. You probably have a cat converter issue. Unfortunately:(

Hey jetro ee dints wanna hear ur life story, just tell us about the thingamajig

I feel yo pain my brother

Lol mine is doing the same thing THE PROBLEM IS YPUR ABS SENSOR BUT YOU HAVE TO KNOW WHICH TIRE IT IS !

What fuse did you take out

It could be the CV axcels

So many issues with this vehicle all give same thing about traction control. I've cleaned out that you just did, replaced throttle body, replaced mas air flow sensor, new plugs, new coils, new converters on exhaust, new brake pedal position switch, about to replace those magnet sensors on the wheels right now. If that don't fix it then idk. I seen somebody say something about a water leak so ima check it to. Geez man just like this guy I still owe bout 6 grand on mine and just spent 6 grand on a brand new transmission to go in it as well. I do believe thus is the worst vehicle gmc ever made!

My Gmc Acadia feels slugish also what can be the problem?

I dont know that i would put any money into it anymore. The motor is ticking and these are know for engine failure. Its not your cats either. Its either your wheel sensor or the brake pedal sensor. If spraying the air filter tube out didnt work.

I wonder will GM stopping making the acadia to many problems

FIXED! My 2014 gmc acadia slt was showing traction control off and service stabilitrak after just a few mins of driving after about 35mph if I accelerated more than 1/3 throttle the truck would cut power in quick intervals making the drivetrain shake hard. So after finding that my brake switch sensor was always triggering the lights to be on and it had to do with the slack that built up over the years in my brake peddle... changing the sensor wouldn't fixed the problem... so I added a small piece of plastic to the sensor to fix the problem. I've been driving it alot over the last few weeks with zero problems! Hope this helps someone.

No fix, just what ifs. I saved you time. Find another video.

What year is it?

Did you ever figure it out

My ebrake light is now on

A timing chain issue would cause a lot of issues as well

Haha this guy is all over the place he said he thinks it is about 10 different things.

Might be timing chain

Too much talking bro.

GMC 😂building home mechanics 🧰 since 1911😒

This vehicle is nothing but junk. Whoever designed this vehicle need to be fired. And they made the repairs expensive. Such as replacing the starter. Something so simple as replacing the starter. You have to remove so many parts to get to it. Even Car wizard said the Arcadia vehicle is junk

I got the same problem rigt now
