My complaint is of the intelilink system in this vehicle. While driving the system would change screens, when turned off would turn itself back on. It would hang up on phone calls, would make all these beeping sounds and change stations on radio. It was very distracting and I feel dangerous in that especially at night as I said would not stay turned off so the beeping and changing of the screen that would make the large(8”) screen go from night mode to day mode and shine into your eyes. When navigating to somewhere system would show that you were in one place, when you were possibly 20 miles from where it would show you to be. Bad because it maybe showing and telling you turn by turn directions and all of a sudden it’s gone. This problem has been diagnosed by a dealer and repaired at a cost of $887.85. Was told that it is a very common repair that they do. Have contacted gm customer service and let them know that I thought a 2017 vehicle with 35000 miles should not have this problem and would like some kind of compensation for the problem and repair

Service trailer brakes light pops up and chimes over and over again. I've never pulled a trailer. It's distracting and will randomly go off. Seems to go off when gas is below 1/4 tank. Sometimes it goes months without happening. Sometimes it happens a few days in a row. The dealership says they can't do anything unless they see it go off.

When I'm coming to a stop and the vehicle starts downshifting, the last shift feels like the tranny is going to fall out. Forceful jerk and clunking noise. It's sporadic. One week it's almost every day, one week it seems fine. The dealership said they have heard this a lot and laughed when they told me the manufacturer has told them it's normal. It's definitely not normal.

The front driver side window won’t roll down or engage; the a/c blows warm/hot on the drivers side vents; the stereo system continues to, “Glitch” changing stations, displaying other information without the screen being touched.

The rear window defrost hasn't been working since I've owned the truck. Doing some research on it.....there's lots of complaints online with issues involving this problem. Some fires also. I did find that there were 160,000 or so recalled in Canada. Same issues. Mostly involving being remote started. Which is what happened to mine. I remote started mine....walked about 50 yards to the truck...heard a loud pop.....the rear window exploded ! Glass went everywhere !! It's definitely a safety issue....especially if someone had been in the rear seat !! I've ran the Vin # and checked with the closest dealer but they weren't any help. It's hard to figure there were so many issues in Canada....but none here. The replacement glasses are made in Canada, about every complaint I read involved remote start during cold weather.....which the rear window defrost come on if the temps below a certain level. Lots of owners were disabling the defrost on the rear window by removing the fuse and or relay.

The contact owns a 2017 GMC Sierra 1500. The contact stated that while driving at various speeds, the vehicle would hesitate and jerk upon acceleration without warning. The contact also stated that while driving at an unknown speed, the vehicle stalled with the check engine warning light illuminated on the instrument panel. The contact had taken the vehicle to a dealer and was informed that there was a service bulletin that was linked to the failure. Moisture could enter the vehicle through the headlights and cause the electrical and transmission failures the contact was experiencing. The contact was given an estimate for the repair. The contact then called Tameron Buick GMC (27161 US-98, Daphne, AL 36526) and it was stated that they were unaware of such a failure. The manufacturer had yet to be notified of the failure.

While in a parking lot, I tried to slowly move forward and then come to a pause. My brakes didn't work quite right and the vehicle didn't stop for an additional 15-20 feet from where I would have liked to stop. Luckily I was just moving forward to get out of the way of another vehicle trying to drive behind me and I didn't have anything directly in front of me that I needed to stop before. If I was trying to stop for a pedestrian I would have certainly hit them. If I was trying to stop behind a vehicle who suddenly stopped I would have ran into the back of their vehicle. There has been a recall on similar vehicles; same make, model and year as mine for what appears to be the same issue. Recall # 19V645000 This has also happened in my garage while pulling in, and in another parking situation. The Service Brake Assist warning comes on the Information screen.

I'm having issues with my transmission/torque converter on my 2017 GMC Sierra SLT 6.2L which cause a heavy shutter and/or shake while driving. I have scheduled a follow up appointment for 11/22/21 after my vehicle was just in on 11/15/21. I currently have less than 57,000 miles on this vehicle. These issues create abnormal vibrations and shuttering under normal driving conditions which can adversely affect control of the vehicle. Furthermore, these issues affect acceleration and deceleration.

Randomly all electronics shut down engine stalls and lane assists wont let me turn wheel while driving in road. Normally at slow speeds. Get random warning lights that go away after seconds. When I activate a window switch all the electronics turn off and on. This happens randomly. No codes have been left to pull up when trying to solve issue. Twice with children in the car in traffic that we have almost got in a wreck due to these random issues.

My brake pedal randomly gets extremely hard, causing my truck to not be able to stop as it should. This almost caused me to read end the vehicle in front putting everyone in danger. There are no warning lights on. There is a recall for this issue that my model year falls under however my vin says no open recalls. It’s a booster vacuum seal problem with the breaks. Very frustrating that my truck is experiencing this recall issue but is not included. This causes a huge safety issue.

I was backing my boat into the water at a boat ramp and my brakes got very hard to push when I was backing into the water. I had to stand on the brakes to get it to stop, if my wife had been backing the truck in, it would have been in the lake. I see that there are no recalls on this vehicle. I bought it about four months ago and don't know the history of any recalls that have been done. I also had the transmission problem with the shimmy, and per the GM dealer flushed the fluid and the shimmy has all but disappeared. I am glad, because when I ask if it didn't repair it would the transmission be covered under warranty, he said no because of the mileage. These reasons are probably why the guy traded it in in the first place.

I have had ongoing issues with my 2017 GMC Sierra Denali Truck's performance since it was purchased in May of 2017 of which I have all the service records to show. In mid-June 2021, the check engine light appeared on the dashboard and I immediately contacted the service department at the GMC dealership in Fremont to schedule an appointment. On 6/18, I dropped the vehicle off for the scheduled appointment. After picking the vehicle up, I immediately noticed that it was shuddering and vibrating upon acceleration of 30-40, 40-50, 50-60 & 75-85 miles per hour. The issue persisted and I returned the vehicle to the dealership on 7/1. After several attempts during the month of July 2021 by the dealership to fix the issue and it not being resolved, I finally contacted GMC Corporate to discuss the problems and options. I was assigned a case number and to customer service assistant Farris. Unfortunately, GMC customer assistance was not very helpful with my claim and was not responsive. At one point, I asked to be referred to a supervisor but was never given that opportunity. Finally, on 8/26, I was advised that based on GMC's evaluation and review of my case, the vehicle would not be replaced or repurchased based on the history of the vehicle repairs. He did not explain to me in detail the basis of this decision. He stated that my options were to take the vehicle back to the Fremont dealership or take it to another a dealership (where I may be charged). I decided to take the vehicle to

Within a couple of days after purchasing the vehicle new I noticed a vibration or shudder when the transmission shifted. Also, the truck would slam into gear almost like being hit in the back end, and on a few occasions while driving on the highway the truck would just downshift by itself thereby causing the engine RPM's to rev above 5,000. It has been to the dealer four times, transmission has been re-calibrated, the new and improved fluid flush and these problems still exist. The truck has just under 60K miles and has started downshifting on a regular basis causing the engine to rev. How long is that going to last before the engine blows or causes permanent damage?

GM has known issues, which I'm sure the NHTSA is aware of. This involves transmission in 2015-2019 model trucks, both GMC and Chevrolet, among other GM vehicles. In my research there have been no less than 13 TSB's issues by GM trying to rectify these issues. The latest TSB states that a new blend of transmission fluid is the fix. In my instance the transmission started shifting hard with less than 30K miles. Took to dealership and they reprogrammed the transmission control module. Fixed the issue for a while but then started back after about 10K miles. In Feb. 2020 with 60K miles a transmission temperature sensor failed on the transmission. I took it in to replace sensor and as a result they had to change the fluid at which time they told me they replaced it with the new recommended fluid. Now at 94K miles it has started producing the hard shuddering at certain speeds. This is the main problem the fluid change is supposed to fix. Well guess what. It does fix it. I'm now scheduled to take it back in on Monday 8-9-21 to have the torque converter replaced. The company I work for has about 12 of these model GMC trucks and 7 of them have had to go back in to fix this same issue. Some of them multiple times. I'm out of warranty and these repairs are not cheap. The biggest safety issue is the tranny could fail at any point going down the road and leave me with no drivetrain and potentially get hit. In my 40 years of driving and owning 20 vehicles between me, my wife and 3 kids I ha
