So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
The info system starts to change screens and jump around. We had it on navigate it locked the screen. You couldn't touch anything then. It started messing with the controls on the -Changing it from the speedometer to music and again would not allow you to touch anything calibrated or anything along those lines. After googling it, several vehicles are having the same problem. All around 50000 miles, our vehicle has about 80000 miles.
This complaint is about General Motors not allowing their Dealer Marty's Chevrolet of Bourne Ma. to recalibrate the odometer and speedometer and other parameters in the computer to match new 18"wheels and tires. The truck was built and set up for 20" wheels from the Factory. The previous owner installed 22" wheels immediately after leasing the vehicle. They never adjusted the computer for this change and as a result the odometer reading read 28700 when I purchased it in August 2023. As a result the engine hours do not correlate to the low miles and the speedometer reading is incorrect. This truck has about 75 to 80 thousand actual miles. When Marty's installed the new wheels that I bought, GM refused to authorize the computer adjustments for the new wheels. GM previously required this adjustment, but no longer does it. This is a safety risk and actual fraud because of the inaccurate miles recorded. I hope you can require them to authorize this adjustment.Attached is an old instruction from GM to dealers for this wheel size change work order.
A/c just immediately went hot while driving. There is a crack in the condenser weld on the upper right front drivers side. Will be at the dealer next Monday.
I purchased my vehicle in January 2022. On 11/18/22 I captured a photo across my dash stating that the trailer brake system needed to be serviced (photo attached). This was the second time this message appeared within days. The vehicle continued to beep and flash for a long period of time clearing out my dash screen making it UNSAFE TO DRIVE. The beeping noise startled me, almost causing an accident on the freeway. I did not know what the warning meant as I wasn't towing a trailer. I wasn't towing anything and could not turn off the beeping sound or the flashing screen, in spite of hitting the dismiss button. I don't know why the message continued to go on and assuming there is an electrical shortage somewhere with the wiring. This needs to be recalled and fixed as it is a manufacturer issue. I do not have any aftermarket parts installed in this vehicle. This same alert message appeared again yesterday 12/5/22 as I was driving back from the airport. It continued for almost 2 hours while on the freeway and again I was not pulling or towing anything. I pulled over, checked my tailgate, turned off the vehicle and turned it back on and the message continued until I got home. It is very alarming and annoying and scared me. This is a big safety hazard and almost caused an accident again as the alert is very loud and flashes across, clearing out your screen, causing you to take your eyes off traffic looking ahead. This time, I was traveling in heavy traffic. Please investigate this further. Thank you
My air conditioning condenser has a leak and leaked all my refrigerant out of the system. From my research and talking to the dealership mechanic, it is a problem GM refuses to do anything about unless your vehicle is under warranty, and they are aware this is a big problem, numerous complaints.
I live in Corona CA where the temperatures easily exceed 100f in the summer months. I was picking my kids up from school yesterday and the AC started blowing warm air. We had to open the windows which brought in even warmer air into the cab. After a little research online, I found there are numerous Sierra owners experiencing the same issue. 99% of the failed AC is due to a "weak weld on the condenser."(see attached photo) Unfortunately, I could not find any recalls or TSBs related to this problem. With the exorbitant amount of Sierra owners experiencing the same-exact-issue, GM MUST be aware of this issue. This should be determined a safety recall, since this is a passenger vehicle, manufactured to provide safe in-cab temperatures for human beings.
Cold start after vehicle sits for a while vehicle shark bites and stutters. When you try and drive vehicle before it-€™s been warmed up significantly. It-€™s a safety concern because it feels very danger and could cause an accident. Alamo At caused my truck to stall out the other day with my children in it and a large accident. Dealership is dismissed my concern and says it-€™s normal gmc defects that I have to deal with. I will sue GMC if I have to.
The trailer brake system on my vehicle suddenly stopped working. I was alerted by a continuous chime and message saying "Service Trailer Brake System." My brakes stopped working and made it difficult for me to stop my vehicle and loaded trailer. It was very frightening because I had lost all trailer braking function and feared I would not be able to stop my vehicle. In addition, the chime and message are non stop and very distracting and cause some components of my dashboard to be inaccessible making things more dangerous. Unfortunately, the distracting and frustrating chime and message continue even without a trailer attached.
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
Back up camera stopped working, appears to be dependent on the weather with temp and humidity. Back up camera will get all static then go blue and call for need of service.
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.
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 another dealership which was GMC, Modesto. The appointment was scheduled on 9/14 and the vehicle was returned to me on 9/15 after they could not diagnose or repair the vehicle. The service adviser explained that I would have to return to the dealership in Fremont. On 9/17, the vehicle was towed to that dealership. On 9/23 at 4:55 pm, service manager Dave called stating "two fuel injectors they put in previously were replaced again and wanted permission for the shop foreman to drive it home."
Driving at approx 55 to 60 MPH with rear defrost on. Began to smell a burning/electrical smell, and within 90 seconds heard a loud bang. Rear window (stationary piece on drivers side) had shattered. Smell presumably coming from the rear window defrost component. No warning lights or messages on the truck. My son was sitting in the rear seat at the time so this is a huge safety risk. This has not yet been repaired. Window replacement is scheduled with Safelite on 6/8, consult with dealer on rear defrost set for 6/10. Photos are available.
Taka recall wireless charger on console does not work with smart phones only on a very select few that are out of date my phone being the galaxy note 9, and my fiancee's phone iphone xr do not charge and frankly the money you pay for this truck to have an accessory option not work is ridiculous
