| Nov 2021 | SERVICE BRAKES | My 2018 chevy silverado started making weird squeaky/popping sounds it almost sounds like something is rubbing against something else when stepping on the break pedal. When driving at any rate of speed the pedal seems to not make the squeaking noise but when I make a complete stop for example at a traffic light and let go of the break pedal and press again I can hear that noise loud and clear even passengers can hear it, Another example would be going in a drive thru of a restaurant that pretty much break pedal is used every 3 seconds as you pulling forward there the noise becomes constant every time stepping and letting go of the break pedal. My silverado has about 80,000 miles on it | Crash: No Fire: No | Unknown |
| Nov 2021 | STEERING,VEHICLE SPEED CONTROL,UNKNOWN OR OTHER | Started vehicle and engine diagnostic displayed that the anti-lock braking system needs to be service, the power steering system needs to be serviced, parking assist needs to be serviced.

| Nov 2021 | ELECTRICAL SYSTEM,ENGINE | Twice now GM has recalled the block heater for my truck. The first remedy did not fix the issue and had to be recalled again. This was back in July 2021. It is now the end of November 2021 and nothing more has been done. My truck requires a block heater in order to start in the upcoming cold months. This will make two years in a row I cannot use my truck when the temperatures fall below freezing. It directly affects my livelihood because I need a truck for work. What more can I do to speed this process up? How is it GM can still sell new diesel pickups with working block heaters, but are not required to fix the older diesel pickups? | Crash: No Fire: No | Unknown |
| Nov 2021 | ELECTRICAL SYSTEM,SERVICE BRAKES | Trailer brake system failure we noticed the sudden drainage of power resulting in death of battery multiple times alert was present after we notice the loss in voltage in battery to battery drainage after research I found that it is usually a short or a bad wiring harness which causes this and could pose a danger considering how I at one point in time have trilled things this could be an issue and a danger to others on the road | Crash: No Fire: No | Unknown |

| Nov 2021 | POWER TRAIN,ENGINE | The engine gave out at 60k miles. Only covered buy the extended warranty I bought. the transmission thunks on downshifts. The exhaust adaptive valve started making a terrible noise at 40k miles. I took it to the dealership for them to tell me my extended warranty doesn't cover it and to buy an aftermarket exhaust because it would be too expensive to replace it. I think they quoted me at $1200 | Crash: No Fire: No | Unknown |
| Nov 2021 | SERVICE BRAKES | It started 400 miles after I bought the truck new and was on vacation with my family, the trailer break system lights started coming on so I detached my travel trailer and took it into a Chevrolet dealership in flagstaff Arizona they couldn’t find out why it was doing it and told me it must be the plug in the trailer it self . So on our trip we were driving threw Zion National Park when my trailer break did not engage down a steep grade and my truck break barley held enough to stop us down the grade , lucky for us the exhaust break gave us just that little bit to help us stop the truck. And now I see people on you tube showing the problem and wonder why GM has not done anything about it , I have paid many time for my truck to be fully serviced and I’m still dealing with this broken piece . | Crash: No Fire: No | Unknown |

| Oct 2021 | TIRES | The contact owns a 2018 Chevrolet Silverado 1500 equipped with Continental Tires, Tire Line: Cross Contact LX20, Tire Size: 275/55/R20, DOT Number: A32AWD402917. The contact stated that while the vehicle was parked, the contact inspected the front driver’s and passenger’s side tires and noticed the threads were coming off in chunks. The dealer was made aware of the failure and informed the contact that there was a recall, but the tires were outside the date of manufacturing for the recall.

| Oct 2021 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | On 10/03/21 at approximately 1251 hours, I was driving my 2018 Chevrolet Silverado which is the vehicle with the above mentioned VIN. As I was traveling towards a heavily traveled intersection in my current city, I approached a steady red signal on the traffic light. It should be noted that this particular part of the roadway is a slight decline towards the intersection and traffic control signal. It should also be noted that on this particular day, there were no inclement weather or roadway conditions that would affect the vehicle to deviate from normal maneuvering. As I applied the brakes at a reasonable distance from the stop light, almost all pressure and power towards braking was lost. As a result, I was forced to apply extensive pressure to the brake pedal as the vehicle failed to slow and stop in a timely fashion. After gaining some braking power, the vehicle and brakes began to shake and produce a clunking sound. This was troublesome because had I failed to stop in a timely manner, I or other motorists could have suffered serious injury or death as a result of a crash at a heavily traveled intersection. Prior to this incident, there were no warnings or alerts provided by the vehicle, dealer, or manufacturer about this issue. As the event occurred, an alert flashed on my dashboard that read “Service Brake Assist.” Following the incident, my vehicle was inspected by a certified mechanic. Said mechanic deemed that the problem with the braking was a result of a failure of the brake booster vacuum system. After doing some research, it is apparent that other years, makes, and models of GMC products suffered the same issue with the braking system. Said issues were remediated with a recall by the manufacturer. This defect also caused numerous vehicle crashes with reported injuries. | Crash: No Fire: No | Unknown |
