ELECTRICAL SYSTEM, SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Own a 2020 GMC Sierra AT4 with 13K miles and I owned the truck for 1 year. All of a sudden my vehicle started receiving multiple warning messages. Electronic Stability Control, Antilock Braking System, ECM, reduced Engine Power, etc. I see there was a recall for 2019 GMC Sierra's for the same issues. Why isn't 2020 GMC Sierra's not also part of that recall ? It is ridiculous that a brand new truck has these types of serious issues affecting so many vehicles. Why is GMC allowed to continue to sell later model trucks after the 2019 recall with the exact same ESC and Anti-lock Braking system problems ?

SUSPENSION
The leaf springs appear to have failed. The vehicle is available for inspection. If the leaf spring brakes, control of the vehicle could quickly become an issue. On 9/24/21 I brought my truck into the local GMC dealer for inspection. The service technician indicated the leaf springs show “possible overloading” and recommended air bags to level the truck. The heaviest load for this truck has been a 4,000 lb. fiberglass fishing boat. At this time, no one else has inspected the truck. The truck, when empty, sits lower in the rear than in the front. If a small trailer is attached, it becomes even worse. Oncoming cars flash their headlights thinking mine are on high beam, which they are not.

SERVICE BRAKES, UNKNOWN OR OTHER
ABS Brakes cut out leaving you with little to no brakes. No warning light appears. This continues on and off over time. Then that ABS warning light came on. When the warning light was on, brakes worked just not ABS. Light would go out and back to the original issue. Took it in to dealership when the light remained on. They reset the light and told me every thing was fine. And charged me $$$. ABS Brake warning light can right back on. Had the manager drive it. Told me it was fine, brakes worked well. The ABS warning would go in and out. Removed the ABS fuse, so I could depend on being able to stop, without having to worry about the ABS cutting in and out for a few years. Watched for recalls, nothing appeared. Noticed on blogs, others were having the same issue. Took it to a great mechanic! Who verified there were no leaks in the brake lines, replaced one line that had been known to have issues on this type of truck and verified there were no air bubbles on the lines. Still same issue, then replaced the computer system for the ABS. No codes ever came up on the computer system that I can recall. Had more issues with the ABS. Would go to stop, (generally on a hill) then when it came to the final stopping, I had NO BRAKES, had to slam on the brakes to stop. ABS Brake warning lights never came on. My mechanic looked and looked and relooked into this. Found from others that blogged that they had similar issues, that one or both of the ABS Brake sensors were not responding evenly causing an issue. Changed out the sensor. All is good now. This issues could have put and my family in danger a number of times. I was blessed to avoid a few accidents by driving far enough behind people and or had an emergency line to pull into when unable to stop. Hope a recall comes soon for these issues to prevent someone from being killed. These took place from about 2015-fixed 2020. Email me with a report number and where I can upload info at a later date, I will do so.

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."
