2017 GMC YUKON Complaints

THE BRAKE LIGHT IS OUT AND A SINGLE TAIL LIGHT IS OVER 500$ Very dangerous to have tail light out and can cause an accident. There should be a recall on these defective LED lights.

Service Trailer Braking System alert intermittent & ongoing for months. Electrical fault? Possible fuse problem? Stranded with kids because car wouldn’t start. Later conducted diagnostics on battery and starter, both normal.

Engine failure 6.2L cylinder failure. Recall already in effect for other years. But it seems that it is needed to be expanded. I had to do a complete engine replacement and all oil related components. Metal was found easily in the oil and oil filter. I was luckily in a parking ramp when it happened so I did not crash. I was already driving for 45 minutes prior on the interstate. Could have been very dangerous at high rate of speed.

My vehicle started making a knocking sound and eventually died on me. I barely made it to a repair shop to check out my vehicle, but had to get it towed back to my home from the repair shop after they told me my engine failed. This happened around 118,000 mileage. I found out that this issue is very common and needs to be addressed for this year and model vehicle. It could have ended very badly for me as I was on the interstate when it happened. Now, my vehicle is sitting and I am unable to use it. Engine would cost me over $12k for cost and repairs.

Engine check light on, Code P0302 cylinder 2 misfire. loud mortar ticking, car makes abrupt jump/move forward.

At low idle speeds like in a parking lot we almost hit another car because the brakes were very hard to press. No power brakes. Felt as I was having to stand on the brake pedal with both feet to stop my vehicle from hitting another car at a grocery store parking lot going 5 mph! A light flashes on and says”service brake assist “ light goes away and drives normal and brakes normal except when you get to a stop sign, or traffic light. This happens a few times and I’m not driving the car because of it because I might hit someone

Yukon break tail lamp problems. Brake lights work intermittently. Very dangerous! The break lights will work intermittently and then work. This was an issue with the 2016 models and GM issues a recall. There is no recall for 2017 which I don't understand because nothing has changed with the manufacturing process. I researched and there is a class action but in California only.

Odometer Fraud. The contact purchased a 2017 GMC Yukon XL. The contact stated that upon taking the vehicle to an independent mechanic for repair, it was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 203,000 and at the time of the vehicle servicing, it was discovered that the mileage was 335,142 in the diagnostic report.

116k miles and the transmission went out. Spent almost 6k on a jasper to replace it. I don’t think I need to explain what happens when a trans goes out. It did all of those things.
