Transmission failure, hard shifting, slipping and loss of power also severe shuddering. Very dangerous driving.

Massive financial loss, dealership stated these transmissions are known to fail. Manufacturer has been notified by numerous complaints. Compensation is warranted

On two occasions while driving at low speed, my vehicle braked on its on a pulled hard to the left; the stabilitrac indicator also popped on briefly. I went online to determine if there were any recalls on my vehicle and found that one of the recalls on the 2016 Yukon was the exact issue happening with my vehicle. I checked my VIN and found that my vehicle was not one of the vehicles with this issue. I called GM to see if my vehicle had just not been published yet. I explain the situation too the customer service person; she understood my situation and informed me that until my specific VIN in identified with this issue, there's nothing that can be done. I'm thinking that until an accident happen because of this issue, there is nothing that can be done. I read that my issue was a problem with the EBCM, which needs to be reprogrammed. I thank you for any assistance with this issue.

The car has all of a sudden had issues with the gas and breaking. When I press the gas, it stalls then rapidly accelerates. It has to be the transmission. Also, is making a noise and will barely drive when pressing on the gas. It does not accelerate!! Could have easily gotten into a car accident! What is going on??

When driving through Eugene brakes suddenly got soft while at a stoplight, then pedal got stiff and very hard to keep pressed. An alert came on the dashboard 'Brake Assist Service' just about the same time the brake pedal changed and car would not fully stay at a stop. When checking to feel what had just happened, by letting up and repressing the brakes, it would not fully stop car, even with all my strength pressing. If another car would have been coming through, my young son or myself could have been killed or seriously injured and I could cause someone seriously to be hurt or killed from being in their lane of travel. I alerted my husband that I was unable to drive the vehicle safely, he is in the vehicle industry and looked up online and found there is a common known problem, recalls, and service bulletins, but apparently not for vehicle years prior to 2017, although this severe failure is seen on 2014 and later; and the manual tests/diagnostics that a person can do in a pinch per the bulletin, recall notice, and articles; and in his trials of how to tell if it is a failure or fleeting problem - nothing alleviated it, all the symptoms are present and system is failing and continually bringing up the brake assist service alert. This is the info that we found on the recall, but didn't appear to cover 2016 year models: [NHTSA campaign number: 20V603. GM's own number for this recall is N202300860.] We plan to get this yukon over to Guaranty Chevrolet in Junction City Oregon tomorrow 10/8. The only thing that has been very recently noticeable preceding this in recent week or so is a slight uneven braking feeling in the motion of the car when coming to a stop. Which it has not done before.

i HAVE A SERVICE SUSPENSION LIGHT THAT CONTINUES TO POP UP ON DASHBOARD THE MOST IMPORTANT ISSUE THAT NEEDS TO BE ADDRESSED IS THE BRAKE LIGHTS. I have previously had the passenger side brake light stop working. In order to repair this you have to order a whole new taillight. My vehicle was approximatly 6 years old when this started happening. First incident (2022 with approximately 65000 miles) Yesterday, I was pulled over by a policeman and both of my brake lights are not working. We found a way to sauder (I know this is incorrect spelling) the broken metal piece back together in the taillight; however, this is not the correct way to fix the underlying problem and clearly it is only a temporary fix because the passenger side broke again in a new spot.

During standard braking operations the vehicle (not a hard emergency situation) on dry ground the vehicle seems to activate the abs system or something similar which makes the braking effort non standard and increases stopping distance. The issue has occurred occasionally for over a year but is becoming more frequent. It has occurred at both highway speeds of 55 mph and almost stopped during parking activities of 2mph.

My 2016 GMC Yukon is hard to stop when pressing brake pedal. Vehicle shimmy’s when pressing the brake and it must be pressed very hard. Have read and watched many videos this is very common issue on 2014-2018 Yukons and Tahoes. This could be very dangerous and my question is, why has these vehicles not been recalled to prevent accidents when it seems to be a common issue and expensive to fix?

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.

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!

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 YUKONS 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.
