Brakes will randomly stop working. When the brakes are pressed you have to press all the way down and then vehicle still won-??t stop and the only way for the vehicle to come to a complete stop is to press the parking brake. Brakes and rotors have been replaced already and it still happens

When I was merging on the fwy my car accelerated and I couldn-€™t slow it down. I had to get off the fwy and break really hard. Driving on the fwy and not being able to control the speed or breaks could of caused an accident or cost us our lives. I have an appointment with the dealer service center on Sept 20, 2022. A few weeks ago I noticed the car was having trouble sifting gears.

In my experience of transmission failure with my 16-€™ GMC YUKON, there was no warning. I had not experienced any issues with the slipping or jerking feel when accelerating or braking as described in the class action law suit. My vehicle had 105k miles, I took it in for regular maintenance including having the transmission flushed as I was told to do so for preventative maintenance. The transmission failed when I was traveling on the interstate with my family and I came upon some traffic so I applied the brake and the whole vehicle bucked and jerked as it shifted into down gear. I was traveling at 30-35 mph in the traffic and the whole time I felt a slipping motion in the car. I made it to a gas station, refueled, and tried to restart my journey. As I leery the gas station accelerating to get back on the interstate, the vehicle would not accelerate above 35 mph and the RPMs we-€™re to the max. At this point, my vehicle was in drivable. No prior warning, no issues that had been occurring over time, this all happened the same day. I towed my vehicle to a Chevrolet dealer where the problem was identified as a failed transmission in need of replacement and failed ABS braking system. The cost came at $6800.

2016 GMC Yukon. I received a letter that stated my Yukon may have a condition where the brake lights intermittently do not illuminate. In March 2020 the drivers side rear brake light did not illuminate. I brought it to a Chev/GMC dealer that replaced the tail light no charge. Now my passenger rear tail brake light does not illuminate. My Yukon has 68800 miles on it and it is going on 6 years old. I still have my letter I received about this issue. Without my tail/brake light it is unsafe to drive my vehicle until I get that brake unit replaced. Will I still be able to my passenger side brake unit replaced at no charge? I haven-€™t been able to get it replaced due to I had total knee replacement surgery in February 2022

The trailer break service light is coming on. There is not a way to dismiss the sound and comes on every few seconds, it's very distracting a HUGE safety risk. I have contacted GMC Valencia California and they have have several vehicles with the same issue / hazard. This has apparently been going on for years yet GMC refuses to put a recall on the vehicles nor take action on correcting this on this critical issue. This is very upsetting and with all the complaints / concerns it appears nobody cares for the lives this defective issue could cause, especially when towing. Thank you.

The contact owns a 2016 GMC Yukon. The contact stated that while driving at approximately 70 mph, the brake pedal was hard to depress and the brake pedal traveled to the floorboard. The contact mentioned that the brake pedal needed to be pumped in order for the vehicle to be operated. In addition, the contact stated the vehicle failed to stop immediately. The vehicle was taken to a dealer where it was diagnosed that the brake line needed to be flushed. The vehicle was repaired however, the failure persisted. The vehicle was taken to an independent mechanic where the failure was undetermined. The contact mentioned while the mechanic was reversing the vehicle the brakes failed to operate causing the vehicle to crash into a person and a vehicle. The contact stated that the lady sustained multiple injuries that needed medical attention. A police report was filed. The vehicle was towed to the dealer where it was diagnosed that the brake vacuum pump needed to be replaced. The vehicle was repaired but the failure recurred. The vehicle was taken back to the same dealer where they informed the contact that the failure was unable to be duplicated. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage 54,000.

Rear driver taillight assembly does not work all the time! One day it works the next day it does not! I had to have the passenger side replaced about 6-8 months ago & it was replaced by the dealer at that time & there was no cost to me as it was under warranty at that time! I think there may be an issue with the LED bulbs! Now the problem is with the drivers side! This is a safety problem and a recall should be issued!!!!It is no longer under warranty & out of pocket cost may be $600 to $1000!

Vacuum pump loses vacuum, and the brakes are very hard. Occurs when sitting still with the brake applied. Also occurs in reverse at low speeds. My wife refuses to drive her car, due to numerous near fender benders.

I see almost 200 complaints and nothing has been done" not sure the point of this website, but, I'm going to put my 2 cents in. My 2016 Yukon denali passanger brake light has gone out, like many, many of other people. Why isn't this a recall? obviously, there is a manufacturing issue that needs to be addressed. After many videos I have watched I see that the circit board comes apart and can't be repaired but only replaced, at a extremly high price. I've also seen many tail light on these Yukon work off and on, so, randomly they can not work at any time and possibly get you rear ended. How do I file a civil action complaint to have GMC address this complaint and resolve this issue" please advise.

On two occasions while in a drive thru line, I would press the brakes and the brake pedal would go to the floor. I had to basically stand up on the brake pedal to get the vehicle to stop. I have not had this happen other than at a low rate of speed. I searched GMC Yukon for any recalls and found that this is a recall with GMC. When you do a search of my vehicle by VIN, it states no recalls are found. I contacted a local GMC dealer and was told that they can't do anything unless my VIN shows the active recall.

I purchased my truck from gilroy Chevrolet in September 2019. The week we bought it my husband had to change the breaks as they needed to be changed. Shortly after within a week from that we started hearing a popping sound from the left front part of the truck. Somewhere near the axel or tire baring. I contacted the dealer and stated they had sold me a car with no breaks and with this mysterious noise. They diagnosed the car, charged me and didn't fix the problem I didn't even get reimbursed or an apology for being sold a car that had no breaks. I have taken my car to a new dealer for further diagnosis. Where they are asking me to pay for a diagnostic fee and deductible I feel the original dealer who sold me this defective car should have to pay since I have paid these due once already. Any time the steering wheel is turned all the way you feel and hear the popping noise.

Brake lights stopped working almost was plowed into by 18 wheeler on I-75. Driver waved us over and informed us that he did not see us till right on top of us. Problem appears to be systemic enough that the GMC service department told us that it was common enough that they kept the brake lights in stock. Additionally there are numerous threads about this issue on the internet and even utube videos on where to remove material to access the offending circuit board to repair the known faulty circuit. The failure of these brake lights could have cost my family and me our lives. The dealership wanted to charge 1600$ to replace the brake lights. I reiterate the brake light failure is common enough that there are numerous threads on the internet to discuss the known weakness of the circuit board
