2020 Chevrolet Silverado 1500 wheel problems

WHEELS

While driving at highway speed, my vehicle developed a serious transmission problem. At approximately 75 mph, it suddenly lost the ability to maintain speed and dropped to about 55 mph despite throttle input. Engine RPM increased significantly and the vehicle had greatly reduced propulsion. Normal operation temporarily returned after the vehicle was shut off and restarted. The vehicle has also experienced harsh shifting, vibration, limp-mode behavior, a check-engine light, and I reported a momentary wheel-lock event. These symptoms create a safety concern because an unexpected loss of propulsion or abnormal transmission behavior at freeway speeds can increase the risk of a collision. The vehicle was inspected by an authorized Chevrolet dealer. The dealer documented transmission-related diagnostic codes including P0700, P0970, P0968, and P0711. The dealer's repair order specifically referenced GM program N242454441-03, described transmission control-valve wear and pressure loss, and recommended replacement of the valve body. A separate repair estimate included the valve-body assembly and related transmission service parts. Despite the dealer recommending valve-body replacement, GM/dealer coverage was denied primarily because P0747 was not present at the time of diagnosis. I am reporting this because I am concerned that transmission control-valve/valve-body deterioration may cause harsh shifting, reduced propulsion, limp mode, or other safety-related symptoms before or without P0747 being stored. I am asking NHTSA to review whether vehicles with the same underlying valve-body failure may remain on the road because the specific qualifying diagnostic code is not present during a dealer scan. The vehicle and transmission are available for further inspection if requested.

With only 70,000 miles on the truck it started to have a hard shudder and wheels locking up. During the wheel shudder it would shift hard as well. We took it to a shop and they said it was our Transmission control module and that the transmission had metal shavings and would fail soon. They also said doing any service to these transmissions can cause failure.We were informed that the dealership is aware these transmissions are all failing. The cost to replace is over $6,500. The dealership should have to do an official recall for this. After some research i found that the dealership has acknowledged the issue by replacing the TCM and uploading new software to put the transmission into a fail safe instead of putting in a new transmission. The issues that the failure causes has made thousands of people have to get new transmissions before the service is even due. A quick search on Google states that 461,000 vehicles were effected and that a recall has been issued, but it has not been officially issued. We need a new transmission and should not have to pay for it on a truck that is so new and serviced timely.

On August 17,2025 I was driving on the freeway when I heard a loud bang and I thought my tire blew but it also felt like I hit something, however I pulled over and tires were ok. I proceeded to go again and this time if can feel my rear tire lock up and then let go. I pulled into a parking lot and my tires had some strips on them as if they where dragged.

Dealership attempting to sell a vehicle with an open recall was more than prepared to let me drive and potentially sell a vehicle with a recall open causing the rear tires to randomly lock up. Made problem known to salesman and said they'd take it off the market. Now, they lowered the price by $2600 as it was previously listed at $25,571, now listed at $22,971. Listing still not down.

While driving down the interstate hi-way, I heard a pop and my truck started to swerve into the adjoining lane. I turned the steering wheel in the opposite direction and the truck started making a rubbing sound and very hard to steer. I finally got it to the side of the hi-way and seen my passenger side front wheel leaning in. The upper balljoint/control arm broke. Luckily no-one was in the lane next to me or it would have caused a serious crash.

VEHICLE BOUGHT NEW FROM DEALER DEC 2020. I DECIDED TO REPLACE SOME LIGHTS SO, I LOWERED THE SPARE TIRE FOR BETTER ACCESS WHILE REPLACING A LIGHT BULB. I NOTICED EVERYWHERE THE SPARE TIRE AND THE FRAME CROSS MEMBERS COME INTO CONTACT THE PAINT HAS RUBBED AWAY AND RUST HAS BEGUN TO FORM. ALSO, THE SIDEWALL OF THE SPARE TIRE HAS CORRESPONDING SPOTS WHERE THE RUBBER HAS WORN AWAY. THIS LEADS ME TO HAVE CONCERNS AS TO THE SPARE TIRE'S AVAILABILITY IN THE EVENT OF A FLAT.
