2017 GMC YUKON Complaints

2017 Yukon Denali manufactured in 2016. It requires the exact same repairs as the 2016 service bulletin N192291660. My Transmission wiring Harness must be replaced including the gasket and filter. The Global Safety Feild Investigation DCS5461 only included 2016 and not car manufactured in 2016 and labeled as 2017. I have the exact same error codes p0711. The Global Safety Field Investigation was issued in July 29, 2020.

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.

First problem started back in May.. it’s went downhill ever since. Hard shifting was happening. GM dealer said I needed a new transmission. Found out from local repair shop that I needed a torque converter ($600) multiple transmission fluid changes (apparently many issues for A Lot of people) changed that. Then had to change Valve Body & TCM. ($540) everything started working but not 100% did a full tune up having multiple misfires constantly then shuttering when idle. Also replaced ECM ($200+)After changing all spark plugs, wires, oil, etc. the AC was having issues had been having issues for months. Kept adding Freon had to replace AC Condenser (works great now, was told by repair shop that’s also very common in these year models. Condensers are all weak in the same spot) just recently October 2022, my instrument cluster started going haywire. Gauges going off and on screens going blank. Had Alternator and battery tested both test fine. No loss of power but when hitting the start/stop vehicle would continue to run and lock and unlock when it wanted. Husband took the alternator out to have it tested again. They tested 3x 1st. Good, 2nd Error, 3rd Bad ( it was overcharging at 16.5V) replaced Alternator ($290) gauges still going haywire, like before it is only sometimes, when they do it’s bad bad.. but I can also drive to town and back 20-30 miles and not the first issue. Just left GM with a new Battery Distribution Fuse Block ($153) because of course it can’t just be a regular ($8-10) mega fuse, hopefully this will fix my issue. We pay too much money for this vehicle to have all of these issues & none be under warranty. I’ve been having the TAILLIGHT ISSUES as well ever since I purchased the car in 2018. When I received the recall on the taillight it was 6 years up to 72,000 & of course my vehicle had 79k miles on it at that time so that’s wasn’t covered.

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.

We took the car into the dealership and complained about the AC and the vehicle being new and they said it was a common problem with this vehicle and offered 10% discount.

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.
