general problems of the 2017 GMC Yukon - part 2

My tail light is faulty. It is working some, shorts out, stops working, I hit a bump, it starts working again. Almost caused a crash, the lady followed me to the store to tell me it was out. Took it to the mechanic and it was working again without any repair. Does this everyday.

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.

Led taillights have both gone out. One was replaced by a "service bulliten" and it didn't cost us. The other recently went out at approx 80k miles. These are supposed to last the life of the vehicle. Replacement cost is $750. After doing research, there is a recall for 2015-2016 GMC Yukon taillights that are the exact same product. I contacted GMC and they refuse to replace the known defect part. This is going to cause someone to get seriously hurt. They know the part is defective or they wouldn't have had a recall on the 2015-2016 models.

Passenger rear tail lamp/brake lamp failure. This is a known issue with GMC Yukon vehicles my 2015-2019 with led tail lamps. Metal within the lamp vibrates loose and cause the brake lamp to fail - thus resulting in no brake lamps illuminating at braking. This would be the second time this issue has occurred in 4 months, with the previous repair occurring rear drivers side and logged with NHTSA for this issue under 11436519. Opening this case as now the other side (passenger failed) with the exact same issue.

Brake lights quit working.

Water in 3rd brake light.

Brake lights are going out due to cracking in the led strip. Slight jars to lights will make them work for a short time.

Led lights are malfunctioning on my 2017 Yukon xl. Causing my brake lights to flicker and then go out completely. I've been pulled over and almost hit from behind due to these lights not working correctly. They have to be replaced by completely removing and replacing the entire light fixture for the high cost of 800+. They are not built to be fixed, just replaced. What's worse is that replacing them only buys you a little time before those again go out. Its unsafe and puts my family at risk daily.

The brake lights fail. First the left light failed, and two days later the right light failed. After researching, this is a common problem with gm and these models. The fix is not just a bulb- the whole rear light assemblies (each side) needs replacing with gm price quotes of $900 a side. We were over 1000 miles away from home.

Led taillight failure rear drivers side. This seems to be a common occurance amongst GMC Yukon denali xl, where the circuit housing for the led board begins failure with fissure within the electrical contact points. The fissure soon erupts causing a shunt within the led semiconductor and causing the brake lights to cease functioning.

1) led tail-lights fail intermittently - this is a known problem gm does not proactively address unless customers complain repeatedly. Puts driver and passenger in danger. This began happening at 25k miles. 2) ac condenser fails - gm will not address as part of a broader recall despite extensive late model customer complaints. This put passengers in danger on any road trip across desert terrain. Gm has been unresponsive despite numerous calls asking for resolution. This occurred at 36k miles. 3) electrical failings - numerous electrical failings - from entertainment system (at 10k miles), starter motor and internal lighting - all failing at 36k miles. Nhtsa must take a look at these manufacturing defects - they are putting customers at risk!.

The contact owns a 2017 GMC Yukon xl. The contact stated while driving at various speeds, the contact noticed that the passenger rear tail light was inoperable. The contact stated no warning light was illuminated. The vehicle was taken to the local dealer where it was diagnosed with the tail light unit needing to be replaced. The vehicle was not repaired. The contact was relating the failure to an unknown recall. The manufacturer had not been informed of the failure. The failure mileage was approximately 106,632.

The driver's side brake light and tail light has failed completely and the passenger side brake light and tail light fails intermittently. This is a safety issue that should be recalled. The vehicle only has 50k miles on it and I should not have to pay $800 per tail light to fix it!.

Passenger side brake light goes in and out and often time stays out. I have read about numerous other people dealing with same issue as it is a manufacturing/quality issue. This is very dangerous. Gmg apparently puts the same faulty brake parts back in car while under warranty then when the issue arises again when not in warranty sell customers a pricey part that actually works. Again, very unsafe and terrible business practice as well.

Without warning, right rear taillight stops working. This is for operating and stopping. Apparently, there are many complaints of this. . . Severe safety hazard for a known part with problems.

The contact owns a 2017 GMC Yukon. The contact stated that the driver's side rear tail lamps were inoperable. The vehicle was taken to mandal Buick GMC (11290 mandal pkwy, d'iberville, ms 39540). The contact was informed that the vehicle was not included in a recall and additionally, the vehicle warranty was expired. The dealer quoted a cost of $760 to have the vehicle repaired. The vehicle was not repaired. The manufacturer was not informed of the failure. The approximate failure mileage was 58,000.

Taillight failure: the failure of led light is a direct result of the alloy base circuit used to maintain continuity. The alloy's inability to expand and contract due to the current design, causes failure of the product. Evident by the videos of repairs online. The alloy is breaking, interrupting the current from maintaining continuity resulting in failure. This is a manufacturing defect where the product should have had expansion and contraction points on such a part to prevent premature failure. The light is nonrepairable without breaching the permanently sealed shell.

Right rear taillights stopped working. Unit is sealed and whole assembly must be replaced, at great expense. This appears to be a common problem but gm will not fix.

2017 Yukon (only been in use for 19 months) ds brakelight assembly (red led outter ring) stopped working.

2017 GMC Yukon denali 4wd. Rear passenger brake light intermittently fails while driving confusing and causing motorists behind my vehicle to receive inconsistent intermittent brake warning lights to alarm other motorists I have stopped. Someone is going to end up slamming into me because of this. It’s a dangerous common failure that needs to be address ASAP. I’m not waiting but gm’s executive corporate office will get the entire bill plus time lost and another bbb review.

Had this vehicle for nineteen months, 50,000 miles, brought new, right brake works intermittently or not at all. These lights are completely sealed and lights are not replaceable, except reverse bulb. Gone over 30,000 miles so warrantee not covered. Dealership wants ridiculous price for replacement. Why would you do this? lights need to be changed sooner or later? isn't it easier to change a bulb rather then an entire expensive unit?.
