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.

Could you do a video highlighting the car's charging issues next? There's widespread issues with Level 2 charging on the Ioniq 5 when charging at higher amperages (typically over 32 amps). 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.

Don't you mean *Brake* I'll show myself out.

At one point about 20 years ago, there were talks of regs that would have had at least two stages of lights, one for braking, and another brighter light for HEAVY BRAKING, or lights that progressively got brighter the heavier they were used, so drivers would know if someone was merely slowing down or slamming on the brakes to avoid an obstacle. It didn't go anywhere in the government, but something that definitely should be revisited.

I've always wanted an "accelerator off" pedal, and progressing lights. There was actually a question on the license test I took 18 years ago. The question was "what is the purpose of the 3rd upper light on the rear of a car?" One of the incorrect multiple choices was "accelerator off light". That stuck with me and I've always thought it's a great idea to add. Combine that with the new style fancy multi bar brake lights like in the thumbnail, you could make them ramp in how many bars are lit, then rose in intensity if it's slamming on the brakes.

If you're at one of the manufacturers that does this, could you ask the team to stop doing the thing where brakelights FLASH every time you press the brake?

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.

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.

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.

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.

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.

I was a witness to the other extreme. There was an electric car in front of me on the highway and its brake lights were continuously going on and off like a Christmas tree. It was incredibly confusing and annoying, especially give the fact that the car was going at more or less a constant speed. I was very happy to take the opportunity of passing it asap.

I own a Kia EV6 and was completely unaware of this issue until following my wife one day while she was driving it. I noticed the brake light only coming on AFTER she was already at a complete stop. Ever since then I always use the manual brake even in I-pedal mode whenever anyone is behind me.

Very simple fix to this issue, program in a function that monitors the vehicle speed, when vehicle speed drops at X rate or above it sends a signal to illuminate the brake lights. Also, the issue you described with the KIA brake lights has been an industry standard on transport trucks since the installation of engine brakes. However I don't see that as an issue because a transport truck is much easier to see, takes longer to stop and is often is moving slower than smaller traffic anyway.

As a truck driver I appreciate bringing up these nuances. As we need more time to stop and anticipate what's the driver in front thinking of doing, or usually not even thinking about it, it's very hard to see at a great distance. When you actually notice the car is showing down without the brake lights you are getting dangerously close.

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 could literally tell when some tesla's were using one pedal drive due to the brake lights not coming on at a decent deceleration, I've nearly rear ended a couple due to this.

Do you have any concern that in a crash scenario your instinct to slam on the break pedal would be decreased due to no longer using it in order to break? That's what my concern is, as in emergency scenarios you rely on instinct, so no longer using the break pedal to stop could cause you to lose that association and thus lose the instinct that pressing the break pedal is what you do to stop. I'm interested if there is any data tracking how many crashes occurred where the driver failed to press the break pedal, and whether the driver was using one pedal driving, because I have a theory that one pedal driving will increase the number or crashes where the break pedal isn't pressed.

I’m a diesel technician. Diesel highway tractors (or semi-trucks) have what’s called an engine brake. In laymen’s terms, it’s essentially a variable valve timing system that slows the engine down. When these engine brakes are engaged, the truck will decelerate similar to that of a moderate brake application. Since I can remember, commencement of the engine brakes would trigger the brake lights on all make or models. 😊

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.

Yeah... engine braking has its place (for controlling the dynamics of the vehicle under road conditions) but any driving instructor should tell you not to rely on it for proper deceleration: "brakes to slow, gears to go" as the advanced driving institutes will tell you (IAM, RoSPA, etc.)

@@Dranok1 That's just crap. I go to 3rd for *every* normal stop, and THEN the brakes as needed. If you can't keep your eyes sweeping thru the mirrors along with everything else, why do you have a stick? You're not driving. Get you an uber instead. No point if you have an automatic 🙄 If you *are* aware of your surroundings the way you should be, you should be able to *instinctively tell* when someone needs that brake information and give it to them when it's necessary. Whole thing is about situational awareness and positioning. But some people can't figure out where the d, o, or g goes while working out how to spell "cat". 🤷‍♂️

Thanks for your informations. Good job.

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.

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.

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.

I own a 2007 BMW, and let me tell you. It as an 'intensity' break light system. If you were press the break slightly it lights up slightly, but if you full press the pedal, the break light intensity is way higher (sorry for the redundancy). I thought it was very good, because it really makes a difference for the person behind me when they see me breaking regularly, to a hard break it shows a dramatic high intense light which definitely catches their attention and makes them aware that the breaking is being done way harder. I've never seen any other car with that system

My brother used to drive a very light manual motorcycle, and he'd complain about the fact that he could usually decelerate by just switching down gears, but he'd have to at least touch his brake to turn on his lights. So I really think this should be applicable to all vehicles

Yeah, I drive an old VW with a higher compression engine. I can slow down quite a bit by downshifting and letting off the gas - and I usually tap the brake pedal to let cars behind me know I’m slowing down. (Old VW - when I say “tap” I actually mean I have to press hard enough to engage the hydraulic pressure switch in the brake system. One day I want to install some kind of switch such that any pressure to the PEDAL will turn on the brake lights. )

The difference here is that a motorcycle has two brakes and you're almost always easily able to use one of them and the brake light switch can easily be activated without doing any actual braking. It's just a matter of being mindful which is something that's important on a motorcycle always. Any time I've been on a motorcycle and using engine braking it's never been an annoyance to simply slightly squeeze the brake lever to light up the brake lights.

We motorcyclists have been doing this trick for decades.

As a non engineer, this would have been the first thing that would come to my mind to get fixed if I was implementing a single pedal mode. (I know, because I already had thought about it before and I thought they would solve it by tying the brakes to an accelerometer and with a speedometer value difference limit as a redundancy) Apparently no-one at the car company thought about this, weird.

Motorcycles have a similar issue. I rarely use my brakes except for the final 10mph or so before stopping because the engine braking is so strong. I have to consciously drag the rear brake when slowing down to warn traffic behind me. The do sell aftermarket brake light kits that use some sort of accelerometer to detect when slowing is occurring to somewhat automate the brake light.

This actually explains a few close calls I've had on the highway recently, where cars in front of me that I was keeping pace with massively slowed down by 30+ mph in a short distance without warning. This, coupled with a construction zone with signs forewarning of a speed enforcement camera has created an extremely hazardous condition of traffic suddenly decelerating from 75+mph to 50mph (the whole highway is a 55) and often without warning due to the traffic backing up out of sight of the signs.

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.

If my memory serves me correctly, there were NYC taxis that had a yellow (amber) light that came on when decelerating. It may have flashed, and I don't know if it went off if the brake pedal was depressed.

Here is my idea to the AutoMakers. Electric cars with one-pedal driving can be confusing for drivers behind them because the brake lights only come on when the driver steps on the brake pedal. To fix this, carmakers could add new lights! Here's the idea: Keep the red brake lights for when the driver hits the brakes. Add 1 or 2 yellow/orange lights in the middle of the back. If using 2 yellow/orrange lights One can be in the top center and the other one can be in the middle or bottom Center. These new lights would turn on whenever the car slows down a lot, even if the driver isn't using the brake pedal (like when they're letting off the gas in one-pedal mode or when a sencor senses a retreat [with the indicated Centimeter minimum] in the Gas pedal). This way, drivers behind electric cars will always know when they're slowing down, no matter how the driver is doing it. Yellow/Orange lights: The Car is Cruising but is slowing down. Red Light: Breaks applied.

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.

What's crazy is those same cars in Canada have an immobilizer system. I'm pretty sure it is required by law. Hyundai/Kia was just really cheap. Immobilizer or not the lock cylinder should not be that easy to remove. My 30 year old Camry is harder to steal. Thats impressive considering I have three random Toyota keys from other cars that will start mine.

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.

So, not an electric vehicle, but my new to me 2020 Lincoln Aviator (and presumably all ford's with this tech) has Copilot Assist 360. It will slow the vehicle to avoid a collision or to assist in traffic jams, all the way to a full stop. It is a wonderful piece of tech that very much reduces driver fatigue. With that said, I was worried that it wouldn't show brake lights when it was slowing down, but can happily report that after some nighttime testing in Chicago traffic no less (I80 to the 390 to 90 to Rockford) last night... It absolutely does activate the brake lights when it automatically brakes the vehicle. This is a relief because after watching this video a few months ago, I was concerned that it might have slipped through the cracks of the software/hardware engineering. So yay! Ford got it right!

The technology exists already at trucks. Most of the trucks i drive got alternative brake systems. A combination between exhaust brake, hydraulic systems inside gearbox, down shifting, i think in US it’s generally known as “Jake brake”. At some level of intensity this systems turn on the brake lights, without touching the brake pedal.

I was following an Ioniq 5 last evening and experienced the lack of brake lights while it decelerated at a significant rate. Hope this gets addressed.
