AIR BAGS
I was hit broad side, by driver running red light. He was doing over 50 MPH I was hit left side forward of left door. My steering wheel airbag did not deploy fully. The crash caused only the steering wheel bag to deploy but it only came out maybe half way, it smoldered so bad I panicked seeing all the smoke and had to crawl out of my truck after kicking open the passenger door because the nose of the truck is racked to the right the passenger door would not open. Other car had full airbag deployed, all curtains and steering wheel

I auto started my truck. We jumped in and I put the key in to start and turned down the heater and pushed the rear defroster off and the passenger side rear window blows up like a shot gun blast. It shaders into a million pieces. Our 2 year old in a car seat right in front of it rear facing. If I was driving with the amount of noise it produced I could of crashed. I see there is a bandage recall but not for the hundred of thousand of the 2014/2020 for back windows just blow out.

Ok my issues is the same recall on many other 2017 gmc 2500HD but not my VIN. Recall number N172120230 (rear wheel hub but loose). In my situation I was driving at low speed went to stop and abs light came on from oil on my rotator, I also heard a knock from the rear wheel. I pulled over and looked under the truck to find my axel seal leaking fluid all over my tire and breaks. I looked into the Facebook form on this problem and found many people with the same issue. Had the truck towed to the dealer where the are refusing to repair and not coving under warranty for 1” bigger tires. My truck only has 39,000 miles and a axel seal should not be going out, and if so should be covered

SERVICE BRAKES
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.

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.

SERVICE BRAKES
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.

SERVICE BRAKES
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.

UNKNOWN OR OTHER
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."

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 have never had a tranny fail. This is the first and GM has know about this issue for years. They need to be made to fix these issues and replace all transmission that are having issues and repay me the money I've already paid and the money I'll have to pay next week. This is ridiculous that NHTSA has not gotten involved enough to force GM to correct this. You need to force the hand of GM to make this right. You know of the problems, now get it fixed!!!!!!!!!!!!!!!!!!!!!!!!!
