GOOD NEWS, EVERYONE! Consumer reports picked up on this video and did testing which confirmed that this issue affects nearly all Hyundai/Kia E-GMP platform cars (and I very much appreciate them giving a shoutout to this video!) www.consumerreports.org/cars/car-safety/brake-lights-can-fail-to-provide-fair-warning-on-some-evs-a9533519285/ And now! Hyundai will fix this. They're calling it a "field service campaign" and it will begin in July. Weirdly, Kia hasn't said anything yet at the time of this comment's posting. www.autoblog.com/2023/06/15/kia-hyundai-genesis-one-pedal-braking/ Now, while I'm glad Hyundai is doing the right thing (and hopefully Kia does soon), I believe we still very much need a clear, unambiguous regulation to unify brake light behavior with features like one-pedal driving. We are still leaving too much up to manufacturers right now.

The service campaign they released to address the issue simply throttles charging down to unacceptably low speeds. Doesn't seem like Hyundai cares enough to issue a recall.

Engine braking is a useful technique, but it should only be used for moderate speed control, like going down shallow slopes or gradual reduction on a motorway. If you're using engine braking such that it warrants a brake light to come on, you're wearing out your gearbox - brake pads are cheap compared to a new gearbox.

This brake light problem was one of the first things I noticed out on the road as I learned to drive. I live in an area with a high concentration of electric vehicles. It bothered me that some of these vehicles could be slowly down so rapidly without any light indicator. I remember speaking with my father about it on many of my practice drives preparing for my test. Vehicles should have some software to activate the light if they are decelerating at a certain rate, even if the driver is not engaging the brake pedal.

The requirements (at least in the USA) are not based on energy use, they are based on Lumen output. Lumens are an antiquated measurement based on the light output of candles, which have a lot of red light. LED's on the other hand typically have very little red light. So what was originally a law to limit the light output of vehicles to avoid them blinding other drivers, ended up being skirted by using light that doesn't read anywhere near as high in lumens while being far brighter.

It’s not that engineers are lazy. It’s that manufactures are cheap. They can save an extra bulb and wiring. Easy money. As far as the software bmw already had this software designed into there cruise control. If it was slowing itself down it would illuminate the brakes if you were slowing down faster than some meters per second rate. This was back in 2008 as that’s what’s in my cars owners manual. People always say the Germans over engineer but they seem to actually think about the important things like brake lights. They also have a multi state brake light system so if your stomping on the brakes it illuminates a second set of lightbulbs, giving you more advanced notice as the driver behind them. They also flash your third brake light when you slam on your brakes and activate ABS. This multi stage braking system should be standard across the board for all manufactures.

I believe this has to do with the car's back door. In Europe,turn signals must be visible at all times whether the back door is open or closed. Which means that if the door opens sideways, you can't have the indicators right next to them. You want the hazard lights to be completely visible when your car is standing at the hard shoulder of the motorway, even while you are grabbing the spare wheel from the (open) trunk. As a result, the European versions of quite a few cars have their turn signals (and tail lights) moved below the door, and only the brake lights where their American counterparts would also have the turn signals and the tail lights.

That stuck with me and I've always thought it's a great idea to add.

Towards the end of the video you mentioned another video about separating turn signals from brake lights, I actually can connect with a real life situation involved with this, I got in an accident last summer because the vehicle in front of me was tapping on and off of his brakes slowing down much below the speed limit. I decided to pass him in the lane to my left but as I did so he turned in front of me and I made contact with the rear of his Silverado with the front of my truck. This Silverado has the exact thing you mentioned where the brake light was implemented with the turn signals, and because he was tapping his brakes while simultaneously using his turn signal I got confused and ended up getting in an accident over it. I highly agree with making it a law that turn signals are to to be amber and separate from the brake lights.

This is a good idea for every vehicle. Tapping the brake when slowing down to make the brake lights flash on and off can wake up the people behind you.

Lighting up is permitted if the delay is more than 0.7 m/s² and mandatory if the delay is more than 1.3 m/s². I don´t know if they changed it or not (They probably did), but i hope that the US also has or will change its Regulations.

I wouldn't worry too much, most new cars have electronic parking brakes and an electric motor onto the caliper for adaptive cruise control and emergency brake assist. Unlike EV's, and some hybrids, there is no regenerative braking, so when adaptive cruise control needs you to slow down it'll let of the throttle as much as necessary and brake if necessary, which illuminates your brake lights. Honestly most EV's with one pedal drive don't have this brake light issue that much. Ironically in my experience driving for a job, the tesla's are bad at this brake light issue, though it's not consistent with everyone, but not everyone uses one pedal drive. I mean I once saw a tesla at a stop light without its brake lights on at night.

I almost ran into an Ionic on the motorway last week because it started slowing down but I didn't see any brake light come on only that the cars in front were coming closer and realized he was slowing down. Now I realize what happened. I also hate the animations they have on the lights and the fact the signals are now apparently all the colors under the sun except yellow.

@BrandEver117 Жыл бұрын

I think the brake light NEEDS to be accelerometer based, (or based on using the speedometer and calculating rate of declaration) because if you used the regen alone, it might turn your brake light on even when going a constant speed (down a hill, for example. you don't want your brake light coming on if you are maintaining the speed limit but still getting significant regen).

@TechnologyConnections Жыл бұрын

This is a fair point! However, lots of people ride the brake to keep a constant speed going downhill so I'm not sure how different it would really be.

@didikohen455 Жыл бұрын

They shouldn't use the brakes for going downhill, that's what low gear engine assited breaking is for. For hybrids and EVs it may not matter in a practical sense, but expecting different driving behavior based on car type just open up things for more issues.

@YorikSar Жыл бұрын

I think it's quite the opposite. The brake light SHOULD NEVER turn on when vehicle decelerates without intent by human or computer. I.e. when it's hitting the wall, there should be no lights. When you go downhill on ICE car, you (or cruise control) apply brakes and they light up the brake signal. It means that you're (or computer is) fighting against gravity, and it's good to know to me who follows you and intuits that braking on this slope is a good idea, maybe we both should do that. If your light doesn't come on, I would think that you're probably ok with going faster, because if you don't brake down the slope, you go faster. Overall lights show intent, not the actual result. Turn signals turn on when you (or your computer, maybe) is about to turn, not when your car pans right when road turns; reverse signal turns on when your switch to reverse "gear", not when you forget to pull handbrake and stepped out of the car. Just like those, brake lights should not turn on when car goes uphill, hits rough patch or decelerates, only when someone (human or otherwise) intentionally slows it down (or tries at least).

@wittyman37 Жыл бұрын

Yeah I agree that brake lights should signal intent and not what is happening. With a manual transmission ICE car it has been possible to slow down very quickly by downshifting for decades (and probably since we started adding multiple gears to cars) but I don't think any manual car turns on the brake lights when the transmission is slowing the car down.

As a stick shift driver and rider (motorcycle) I tap the brake when engine braking as the lights won't turn on. I guess you can do the same until the update/fix. While letting off the pedal, gently tap the brake pedal enough to engage the brake light switch.

@WhoStoleMyAlias 4 ай бұрын

Yes except as the guy says the brake lights will already come on when you take your take your foot of the "accelerator" pedal completely. And the bad thing about that is of course that this will also make you decelerate even more. So no, this whole one pedal driving concept is not well thought about at all and should be banned and regenerative braking should also only occur when there is an actual intent of braking, not when traffic in front of you gradually slows down or when entering an area that has a lower speed limit. Further more we should start teaching people how to be responsible drivers again, because to me it is amazing to see people drive around while apparently not even knowing where the light switch is located as they ignore traffic signs that state you need to turn the lights on.

This video and your other one about crummy signal lights came to mind recently when i saw the stupidest signal/ break light design ever. I didnt catch the make/model cuz it was dark but the break and signal were combined into one red strip along the length of the bumper. Buddy was driving kinda stupid anyway (like signalling in the middle of switching lanes). So half the bumper is blinking pretty slowly when the signal is on and the rest of the bumper lights up when the break is on. So it can look like the signal lights are being switched back and forth sometimes and its really unclear whats being communicated. Thought folks here would enjoy this spotting of trash design in the wild.

My instructor would warn me about this slowing the car, but not engaging the brake light ; and advised me that if I REALLY wanted to engine brake, I should at least rest my right foot a tiny bit on the brake pedal, since the light activation is usually super sensitive and turns on way earlier than the brake pads actually do any substantial slowing down.

Fantastic video - I was quite surprised to see that the Ioniq's brake light didn't come on when the G-force approached -0.3G! However, I noticed that you didn't touch on the blended brake control feature that's integral to the one-pedal driving system, hyundai referred to as 'i-pedal.' This feature explains why manual regenerative braking doesn't bring the car to a complete halt. Having driven the Ioniq myself, I must admit I'm not a fan of the shifter's regen settings.

@xavemsk88 3 ай бұрын

Somebody here already wrote about downshifting on mt cars. I drive one and have to say there are not many situations where braking with intensive shifting down is useful. Usually engine braking is used to get a constant speed on downhills w/o heating a convient brakes. But on motorcycles an accelerator design is allowed to control speed of throttle opening only but closing too. (A reverse moving of car pedal is limited by spring force). So this makes downshift braking much easier and faster and when I ride, I almost don't use friction brakes.

@AfonsoBucco Жыл бұрын

and they could work in parallel. So pedal activated system will turn the lights on even in case of electronic fail. Of course there is a chance of electronic fail turned on, but it will be easier to be noticed by the driver than opposite. Is not the worst Boy-Cry-Wolf situation. Talking Boy-Cry-Wolf problem I agree that should exist regulation about how much acceleration it have to flash on. But ANOTHER Boy-Cry-Wolf problem will still remain: even under regulated G there are still situation where car naturally slow down and you DON'T want to say "I am breaking": For example: climbing a hill. If the lights turn on the car behind with already also naturally fell the deceleration will think you are stopping, so they will also break unnecessarily. The traffic will be worse in some places, it will be annoying, and when you are really stopping the guy will not really know (the Boy-Cry-Wolf problem). BUT IT ALSO CAN BE SOLVED: just putting exception on accelerometer action based on level, it would be also cheap, once normal smartphone accelerometer also can measure the level. Everything I said is extremely cheap to mass product, maybe not very very cheap to develop properly.
