This has been going on for a while now, but it's getting worse overtime. If I push on my brakes more than twice the brake pedal locks up and I have to push extremely hard to get my vehicle stopped.. luckily I have never been going fast and had to worry about this. This is normally when I am pulling into a parking spot or I am backing up that I have to tap on my brakes a few times. A couple of times I have bumped the pole in front of my parking spot due to not having brakes. I just put in a general date as to when they started to get worse.
So the shock strut system up front has a grommet that holds it in. The repair order said they put a shock simulator in the car and it gave false reading saying it was good and it came out broke break line and caused me to jump a curve to stop the vehicle. ALSO Now the THE TAIL LIGHT IS OUT AND NO WAY TO REPAIR IT NO ONE HAS THE LIGHT. Also this car is on its third transmission
Tail Brake Light failure The tail brake lights have gone out on a vehicle that isn't 10 years old yet. Tail lights should not go out this quickly and the dealership will kindly replace them at $1300 per tail light. This is absolutely absurd! It is available for inspection. This definitely puts myself and others at risk! Yes, this problem has been confirmed and inspected by a GMC dealer. Advised this is a very common problem with this vehicle. There are no warning lamps or messages to alert when the brake lights have gone out. Instrument Cluster failure The instrument cluster is also faulty in this truck. This is the 2nd time within a year that i have had issues with this. Safety concern is that you will not know if the vehicle is running hot because the gauges stop working. Also runs the battery down as the fan continues to run for about 10 minutes after the vehicle is turned off. …

I purchased a 2017 GMC Yukon Denali brand new off the showroom floor. I have maintained the services thru GMC dealership. I had to replace the struts and rear and front shocks due to hydraulic system leaking and locking up my brakes and causing extra pressure on my braking system to stop my vehicle. This cost me over $5000 to replace out of my pocket and I saw there was a previous recall in 2019 for similar problem but i was told my issues were not covered under the recall. I have also had to replace both taillights within 2years of purchasing my brand new vehicle and now they are out again. This will be my second time having to replace the LED tail lights that cost over $375 light which were stated as never go out of lifetime guarantee. You cannot just replace the bulb you have to replace the whole tail light which takes weeks to come in and then additional labor costs. The previous
1.)Rear Brakes are not functioning properly. They still have pads but when you press down to pump the brake it fails. I was told by a mechanic that they other GMC vehicles have had recalls on this, but mine is not showing one. 2.)The suspension on this vehicle has never worked properly. It rides extremely rough. It has some special suspension in it from a shock perspective, but it feels as if it often fails. 3.) I had to replace the torque converter in this vehicle last year, and the fluid that runs through it. Apparently this is a known issue with no recall. 4.) the transmission slips when the vehicle shifts gears. It shifts hard. Also a known issue with no recall.
