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.

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.

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.
