My complaint relates to a known defect in 2015-18 GMC Yukon (and similar GM models) and defective brake lights. The left brake light in my 2016 GMC Yukon went out in approx early 2019. It was repaired under warranty. In November 2019, by right brake light went out. It was the same problem as the early broken light. I had less than 36,000 miles on the vehicle. I leased the vehicle in approx Sept 2016 and the dealer claimed that the vehicle was past (less than 75 days) expiration of the 36 month warranty. So, the dealer quoted me $950+/- dollars to replace the entire housing. The dealer rep explained that the entire housing had to be replaced because it was led and didn't use a bulb. The dealer rep told me this is a common problem. I was incensed and refused to pay. I went home and googled the problem and found out that this is pervasive with the 2015-18 Yukon and other similar GM products. I also found a fix that was much less money only required about 2 hours of my time. This is a safety defect and, based on the dealer rep comment and google research, it is a well known problem. For example: Https://www.cargurus.com/cars/discussion-T53845_ds768963 NHTSA id number: 11291414 NHTSA id number: 11299968 NHTSA id number: 11297087 NHTSA id number: 11291113 NHTSA id number: 11286914 NHTSA id number: 11282957 NHTSA id number: 11282130 NHTSA id number: 11282097 NHTSA id number: 11278307 NHTSA id number: 11265307 NHTSA id number: 11265384 NHTSA id number: 11256174 NHTSA id number: 11254155 NHTSA id number: 11253481 NHTSA id number: 11246544 NHTSA id number: 11246035 NHTSA id number: 11241057 there are many others as well. A broken brake light is a safety defect. GM should be forced to recall all of the 2015 - 2019 and replace the brake lenses.

Brake light on vehicle works intermittently and is no longer safe. This is a problem GMC is well aware of and no solution in sight. Cheap metal board brakes inside the lens and leaves you with no brake light. I do not want my family to be rear ended because of this professional grade" brake light failure, at any time on road.this is a 2016 GMC Yukon with 22710 miles as I write. Brake light has failed while moving on the city streets. This failure is currently on the passenger side brake light. Trying to make appointment for repair of this professional grade brake light" before the other one brakes and put my family at risk of a accident.

Vacuum pump. Engine light on. Brake light on. Drove horrible & could hardly stop at times. City street

- Elkhart, IN, USA

While in slow traffic, I pressed brakes to stop. The brake peddle did not compress down, causing me to have to enter the highway median to keep from striking the vehicle in front of me. The median was wet and muddy. Our Yukon had to be pulled from the median by a good samaritan.

Low speeds the brakes fail, when pressing on brakes you get a hard brake pedal with no brakes.

Rear brake light led strip is out. Vehicle only has 37K miles on it. Dealership will not repair it but wants to sell a new brake assembly for $750 each. If you tap on the light assembly, it comes on momentary and goes out again. Brake lights on both side of vehicle continue to flash rapidly, there has to be some type O ofelectrical problem to cause this issue,

- Jacksonville, FL, USA

When in traffic at slow speeds the brake system shuts down and takes my body weight to stop car. Had checked and no visible leak. Now GMC has a fix but charge to fix if over warranty mileage. Second issue is the transmission went at 96,000 miles while highway driving loosing all top end gears at 65 mph. GMC did nothing but dealer helped on tho as well

- Canton, GA, USA

Vehicle in motion and brakes would not work unless you put all your body weight on the brakes, and then just barely. Happened multiple times on and off both at high rate of speed on highway and on city streets. Took into GMC dealership and they replaced the vacuum pump for the brakes -- problem solved after spending $800. We are lucky this is a major safety issue that could have caused a serious accident. I understand this exact problem is a known problem currently being investigated. Please finish your investigation quickly and issue a recall -- somebody is going to get killed if this is not fixed. I look forward to being reimbursed from GMC when the recall is finally issued.

Vacuum pump went out on my vehicle resulting in almost being hit by a semi traveling 65mph. I had to call a wrecker to pick up my vehicle and have it towed to the dealership as it was no longer safe to drive. I paid out of pocket for the wrecker and the repair because the vacuum pump was no longer covered under warranty at 38,633 miles. I was leaving a driveway at a slow speed to turn onto a farm to market road and my brakes would not work.

Third time this happened, first two times my husband was driving(he called the dealership and they said they had not heard of any problems) and when it happened to me it was scary. I had my kids in the car, no injuries and no one was hurt, thank god. I was going through the drive thru stopped at the first window, accelerated to next window (low speed) and didn't stop... it was the like the brakes locked up, couldn't press down at all. Called the dealership first thing in the morning, same thing didn't know of any issues. Well I googled it and it is under investigation, so I kindly printed off all the articles so they could let other customers know there was an issue (they didn't care to keep that but did admit they knew there had been some issues). Of course my car is just out of warranty so they said I would be responsible for any issues. Again, this is a safety issue and there should be a recall!!! they should be paying for it and thanking there lucky stars no one was injured. The total came to $950, they asked if I wanted them to fix the pump, belt and belt kit (I asked if this was the issue others were having and he said he believes so). What was I going to say no" did I really have an option?" the brakes weren't working!!!! kind of a big deal!! of course I would like them to pay me back (they did give me a credit of $208) but I do believe they need to do a recall before someone gets hurt.

Brakes fail at low speeds and when reversing slowly. Can replicate problem. Searched internet and this appears to be a widespread problem. Service bulletins have even been written. Why no recall for a widespread issue that could have catastrophic consequences.. vehicle has less than 50000 miles.

- Helena, AL, USA

When pressing the brake petal at low speeds and in bumper to bumper traffic the brake pedal becomes very hard to press and very difficult to get the vehicle to stop. This problem also is noticed when backing the vehicle in reverse and into a parking spot.

GMC Yukon 2016 rear lights are defective. This is the 2nd time they have gone out and it is not a quick fix to replace. Cost is approximately $750 to replace a light that will go out again due to poor manufacturing and quality. The first time it went out was only a year after purchase. This is the 2nd time it has gone out and is not D=covere under warranty. These lights are not made to last a decent amount of time. There are numerous issues reported regarding these rear lights.

- Ripon, CA, USA

While exiting the Ohio turnpike, my brake pedal began to stop depressing completely- to the point where I couldn't push down at all. It felt like an over-pumped keg. As I continued my exit toward the toll booth, it seemed that the ABS were engaging, but I wasn't in an emergency braking situation. The rest of my journey home was uneventful, until I arrived home. I pulled into my garage, and attempted to back out so I check under the vehicle to make sure there wasn't anything leaking. As I backed out, my brakes would not engage properly again and my car rolled back down my drive way. The car stopped and I parked it where it was. Later in the day, I was able to pull the car into my garage without incident. I took the car to chesrown GMC (the dealership where I purchased the vehicle). They advised they had never heard of such a situation and had me being vehicle to them. I couldn't replicate the issue with them, but left the car with them so they could check it out for issues. They replaced the the brake vacuum pump. Today (7/31/17), the brakes started to behave in the same manner as when they failed on 7/16/17.
