2017 GMC YUKON XL Complaints

When accelerating the car starts bucking, after driving some more shakes like going over speed bumps.

One rear brake light was intermittently malfunctioning even though the vehicle only has 80,000 miles and is a 2017 model. Upon researching online, I saw that 2015 and 2016 models were recalled for this. 2017 was given a limited term to have the vehicle fixed IF they were experiencing the issue. I was not experiencing the issue at the time, so I was responsible for a large chunk of the cost of repairing the light through the dealer at GMC. GMC did inspect the vehicle. The company was made aware of the problem. The dealer discussed it with them and they agreed to pay half as a "favor" basically to have the rear light replaced.

When backing down a boat ramp for a day on the lake I experienced extremely high rake pedel effort and abs engaging with no wheel slip for skid. In order to keep the vehicle from going into the lake I had to apply the parking brake. No warning lamps illuminated. The dealer states it is a faulty vacuum pump.

AC stopped blowing cold air. Took it to the dealer and they are saying based on where the leak is it needs a new compressor. There is a recall / special coverage for other GMC 2015-2017 for this exact issue.

The paint on the hood is peeling/flaking and is degraded. Right air shock is leaking causing the vehicle to continually pump up. I have the tow package, and with the air shock leaking, it does me no good. My air conditioner has not been cooling for a while. I started noticing it when it was hot in December, 2022. Would have thought it was a simple leak. The port valves have been changed. Air is still not blowing cold. My vehicle uses the R1234YF which is very expensive per can. After spending $72,000 on a vehicle, you would think that it would not be failing so soon. I understand 1) there is a class action lawsuit regarding the peeling/flaking of the paint; 2) that the ac condenser has a recall and also, the "leaky" air shock; however, my VIN is not included in any of these recalls. Upon the pleading and begging for recall information on brake lights and the brake system, those after sometime, were actually fixed by the dealer. I feel like I purchased a lemon. This was supposed to be my forever vehicle. To make matters worse, my vehicle display freezes when you are driving down the road, which includes while you have navigation on, I guess I will just get lost. I have had warnings about parking/collision alert just not working and will not let you push the button to turn it back on. I am not understanding why all of what is happening. I work everyday and have to take off work to take it to the dealership. I have never been so disappointed in a GM product, my vehicle is a piece of crap. I have an appointment at the dealership on April 19, 2023, we will see where this will take me.

My driver side tail light is not working. The passenger side tail light flickers in and out.

Rear brake light has stopped working. GMC dealer quotes $990 to replace one tail light assembly. It appears to be a common problem caused by a weak conductor that breaks inside the assembly. Because of the high price quoted by dealerships, people are resorting to fixing it themselves, like in this video: https://www.youtube.com/watch?v=NxluJqB0gWU This is dangerous. This part should not be breaking so quickly. It should not be allowed that fixing brake light be so expensive by the manufacturer.

This is due to the issues that many vehicles like this one that continues to be a problem. This issues has caused my vehicle to be unable to accelerate and has caused it to stop in the road.
