2017 GMC YUKON XL Complaints

Transmission failed with no symptons. No indications of potential issues prior. All recommended service checks done with vehicle, oil changes etc... 75,026 miles. Pulled up to a red light in heavy traffic and transmission would not engage. No forward, reverse, or in Low 1. Tried 4 wheel and 2 wheel drive. Nothing. Yukon 2017 XL SLT model.

Not sure if this is the correct raea to notify regarding this incident. I had windshield replaced by Safelite Auto Glass in Cadillc Mi.After the service the technician said he calibrated everything and all is fine. Upon my initial driving after the windshield service the vehicle engine light was flashing and the display was telling me the advanced collision and lane departure warning systems were inoperable. Additionally the vehicle would not accelerate. The vehicle could not be driven safely. I contacted Safelite in Cadillac Michigan the next morning and was initially told the warnings have nothing to do with the service they performed and they do not have to do anything to help me. The manager advised that they ran 3 scans with their equipment and all scans came out good. The manager is saying that confirms everything was OK. I see that as an admission of something being wrong since the technician ran 3 scans. Why run additional scans if all is good. What he was seeing is that the vehicle was displaying warning lights and was not running properly. That is why he kept running scans over and over. Even after 7 scans now they are still saying it's not their problem. Obviously their equipment is incapable of calibrating the new windshield to the vehicle. Additionally they have caused a problem within the engine control module by hooking up faulty electronic device. The vehicle is inoperable. Additionally Safelite knows that they are incapable of performing windshield replacement on this vehicle. The technician no more than left my driveway and I received a text from Safelite saying: "Modifications to your vehicle may cause your advanced safety systems to not function a intended" That is admission thjat Safelite knows they are incompetent in this matter. The windshield is in of the most important safety feature in a vehicle. It is unacceptable the an industry leading automotive aftermarket company is continuing to operate this way. Please look into this.

The drivers seat broke and front airbags did not deploy. The seat broke during rear end collision which pushed the seat back so I was no longer able to reach steering wheel or brakes to stop. Went thru on coming traffic to end up on wrong side of road in ditch. Police inspection, insurance inspections, auto repair inspection No warnings.

UNKNOWN 4 times in the past 6 months, while parking the vehicle (turning into a spot, left or right) or slowly turning to pull up to a security code box, the car completely begins to lose power in drive, and has lost power while in drive twice. The dash begins to flicker to the point that you can't decipher which error codes are showing up. Most recently, the Trailer Brake Service message was on before it died. We were not towing anything, did not have tow mode on, or anything like that. The parking sensors were on for all these instances...regardless if we were parking or not. I can't confirm if that is the issue or not. It was pretty dangerous when I was pulling into my parents driveway along a busy road when the car did this before I was completely off the road...with my 3 young children in the back 2 rows. I know the battery is new. I did have the dealer look at the brakes about a month ago, because I felt they were soft. They said they were fine. They and myself checked the reservoir for brake fluid low. Was in normal range. Starter was replaced in March time frame. I feel this is related to the factory trailering system wiring harness or something.

The contact owns a 2017 GMC Yukon XL. The contact stated that while reversing, the brake pedal became hard and unresponsive. As a result, the contact crashed into a guardrail. There were no reported injuries. There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed that the brake assist pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified and a ticket was submitted. The contact stated the failure was related to NHTSA Campaign Number: 19V645000 ( Service Brakes, Hydraulic). The failure mileage was approximately 59,000.

My brake lights work intermittently. If you tap the actual brake light they will flicker on and off. This puts others and my self at risk as the indicator for by braking system is not functioning properly. My vehicle has been to my local GMC dealer with a replacement cost of $950.00. I also received a written warning from my local police department. There are no warning notices.

The contact owns a 2017 GMC Yukon XL. The contact stated that the check engine warning light illuminated on the instrument panel. The contact stated that the vehicle was running rough. The vehicle was taken to the dealer for diagnostic testing. The dealer stated that the fuel injector had failed and the vehicle was experiencing the failure stated in TSB: N182198000 (Engine). The manufacturer was contacted and stated that the vehicle was not included in TSB: N182198000. The manufacturer offered no additional assistance. The approximate failure mileage was 32,000.

I was driving and all my sensors came on stating they needed service including front camera, blind spot notification, lane departure, emergency braking etc. upon parking I exited my vehicle and walked around the rear of my car to find multiple wires hanging down burned from my exhaust. I took my vehicle to an automotive repair shop and not the dealer since it was no longer under warranty. They said they had never seen anything like it. It appeared the harness that holds the sensor module/wires disconnected from the car. It appears to be held in place with some sort of industrial glue. When it failed it was hanging in front of the exhaust and melted all of them. This disabled all of these sensors. I now have to pay for a new harness and to replace all of these sensors. In researching online it appears water intrusion has caused issues in some models and caused these harnesses to fail. I’m wondering if this is the cause even though this model isn’t part of the recall.

The rear break lights malfunctioned and will quite working periodically there has been no inspection from a dealership at this moment and driving at night time puts me and my family at risk due to the fact that I could be rear ended and cause a major accident and my vehicle has no warning light or service light for this problem.

Just driving along yesterday in my Yukon, and when I stopped another driver pulled up to me and informed me my right rear brake light is not working. Upon further investigation, it comes in and out (sometimes it works sometimes it does not). I had this same issue with my 2015 Yukon, I would have thought GM would have this fixed by now, very expensive fix on my 2015, assuming it’s the same cost or close. Very dangerous to have a brake light out and reduce another drivers reaction time to stop and prevent a rear end collision. Furthermore the vehicle has no indication that a light or bulb is out, a lot of vehicles have that programming, surprisingly this does not.
