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. The manufacturer was made aware of the failure but informed the contact that the tires were beyond the three-year warranty and did not provide any assistance. The failure mileage was unknown.

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.

When driving the brake pedal goes soft. In parking lots, areas of low speeds, making u-turns the brake pedal goes all the way to the floor and doesn’t stop. The brakes completely stop working until you release and pump the brakes again quickly before hitting something or someone.

Service Brake Assist warning on message center. Brakes go from power to manual

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

Truck loses power driving down the road. The service trailer brake system warning comes on the dash. The battery dies because of this also.

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

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?

I was on highway 65 coming out of Rocklin Ca going back to Yuba City Ca. The Chvey Silverado with out any warning it just lost power and I had to pull over. I am glad I was on the slow lane. If I was on fast lane with a big rig behind me. It would have been bad. After pulling over the Eng Light when on for the first time since I have owned the truck. Not any time before. I thought if a family with children was in the fast lane and this happened it would not be a good out come. I had it towed to my home the chevy dealer was close. On July 18 I had it towed to the dealer I had the truck towed to Wheeler Chevrolet In Yuba City They replace the engine computer and the tranny computer . And to day Aug 1 , 2021 they said they would fix the tranny. I am wondering if they know what they are doing ? This is very disturbing I am very apprehensive about the safety of the truck if this were to happen again !!

The drivers seat moves while turning. It feels like the seat is sliding when turning then there is a "catch" and a sudden stop in movement. While driving and making a turn the feeling the seat will come unbolted from the floor is a unnerving feeling to say the least

Radiator developed a leak as described in General Motor's Service Bulletin PI1513F dated January, 2019. Safety was put at risk due to having a vehicle which could have a sudden radiator failure and permanently damage the vehicle. The Dealership I had my radiator replaced at would not state if they have had this issue occur often. No warning lamps or messages prior to the radiator losing 1.5 gallons of coolant. My first symptom was the engine overheating.

Consistent failure with AC condensor for 2014 thru 2019 Chevrolet trucks. So common, should have been fixed or replaced.

The trailer brake control module stopped working on the interstate while pulling a 37' fifth wheel camper. This defective part caused the truck to not have any electric brakes on the camper. A warning message appeared on the dash. A new trailer brake control module fixed the problem. Since the vehicle was out of warranty (37,878 miles) the part was not covered by the dealer. The dealership where the part was purchased informed me that it was a common problem. This problem occurred while traveling at 65 miles per hour. There was only the truck brakes to stop the camper without the trailer brakes working. This is a serious problem and should be addressed.

For months now, my 2018 Chevy Silverado 1500 has a “service trailer brake system”notification on the the dash that repeatedly pops up every 5-15 seconds while the vehicle is on, including while driving. This, along with the pinging sound that comes with the notification, makes the vehicle difficult to drive due to the constant distraction the notification makes. I have tried taking issue with the dealership but they are not helping whatsoever. From my own research online, I have seen hundreds of other people experiencing the same issue. Please help us eliminate this distraction by forcing a recall and thus making the roads safer for everyone. Thank you.

The rear seat belts do not retract once extended. The emergency locking mechanism locks the belt, but the belt does not retract. Installation of car seats that require seat belts to be locked and retracted until tight is not possible.

AT SLOW SPEEDS, SUCH AS WHEN PARKING, THE TRUCK’S ELECTRICAL SYSTEM SHUTS DOWN, I LOSE POWER STEERING, DASH LIGHTS, RADIO, AND THEN THE TRUCK RESTARTS ITSELF AND CONTINUES. THIS HAS HAPPENED MULTIPLE TIMES AND CHEVROLET DEALERS DON’T W WHAT THE PROBLEM IS. IF NEARLY COLLIDED TWICE DUE TO LACK OF POWER STEERING.

While driving highway speed on cruise control the RPM levels start jumping up and down and it feels like your driving over the rumble strips. It only last for a second or two at a time, but it does do it a good amount of times while driving.

NEXT DAY TURNED INTO A DRIVE THRU AND IT FLICKERED AND CAME UP WITH SERVICE STABLI TRAK. I TALKED WITH A PLACE THAT COULD HOOK UP MY TRUCK TO SEE IF ANYTHING WAS WRONG. THEY COULDNT FIND ANYTHING. THEY SAID THEY DROVE THE TRUCK AROUND AND NOTHING HAPPENED. I LEFT AND IT SHUT COMPLETELY DOWN ONCE AND FLICKERED TWICE. IM HOPING THIS IS COVERED UNDER WARRANTY. IM AT 43000 MILES. HELP!

The DIC and infotainment both change settings on their own. It will change radio stations or call people on the infotainment and the DIC will change information displayed. The safety issue is it will also flash that the trailer has been disconnected/connected and when it thinks the trailer has been disconnected the trailer brakes will fail to function. It is a known problem with the display issue but I am unaware of any reports on trailer brake function. I have had a few serious conditions on two trailers when the truck does not recognize the trailer being connected and fails to apply the brakes.

RADIATOR LEAKING FOR NO APPARENT REASON. TRUCK HAS ONLY 54K MILES AND IS IN EXCELLENT CONDITION SERVICED ACCORDING TO SCHEDULE BY CHEVROLET DEALERSHIPS.

FAILED TO SHIFT GEARS. JERKING AND SHAKING. BUNNING SMELL. FAILED TO MOVE IN DRIVE OR REVERSE. CHECK ENGINE LIGHT EVENTUALLY CAME ON. STILL HAS TRANSMISSION FLUID.

WHEN COMING TO A FULL STOP, THE TRANSMISSION DOWN SHIFT REALLY HARD. IT MAKES THE VEHICLE JERK FORWARD. IT DOESN'T MATTER IF YOU ARE GOING UP HILL/DOWNHILL OR ON A FLAT ROAD. I TOOK IT TO THE DEALER AT 4K MILES FOR THIS REASON AND WAS TOLD IT WAS A KNOWN CHEVY ISSUE BUT THAT THEY HAD NO WAY OF FIXING IT.I TOOK IT BACK A SECOND TIME AT 5K AND WAS TOLD THE JERKINESS AND POOP THE TRANSMISSION DOES IS A GM DEFECT DESIGN BUT THAT THEY HAD NO WAY OF FIXING. DEALER SAID OTHER OWNERS HAVE INSTALLED A 3RD PARTY SINGLE PIECE DRIVE SHAFT WITH ANGLE SPACERS BUT THAT WAS NOT COVERED BY GM WARRANTY. DEALER ESSENTIALLY WANTED ME TO FIX THE HARSH SHIFTING AND CLUNKINESS BY GOING WITH AN AFTER MARKET PARTS PROVIDER. A WORK AROUND THAT HAS SEEM TO MAKE THE ISSUE MORE BEARABLE IS PUTTING THE TRUCK IN 'TOW MODE' IT SMOOTHS THE RIDE OUT BUT IT TENDS TO MAKE THE TRANSMISSION RUN ABOUT 20'40 DEGREES HOTTER
