STEERING
On Sunday Nov. 16th, my steering wheel felt like it was "slipping", akin to how it feels when your serpentine belt tensioner is failing. I checked it out while wife turned the wheel, didn't see any problem, and we went on our way. Later in the day as we were leaving a parking lot, the problem occurred again but worse. And we got a warning about trailer brake controller needs repair. After reviewing similar problems on Reddit, I found it was still safe to drive, so we drove home without further incident. Monday I decided to take it to O'Reilly auto parts and have a code scan done. Except, as soon as I turned out of the driveway, my wheel completely froze up solid. I could NOT move the wheel (q2)! Since the wheel was still turned, I backed it into the driveway and we took our car to buy our own code scanner. It showed more than just one fault code for the brakes, there were 5. I called Fox Chevrolet to schedule al appointment for the next day. Fortunately, the failure occurred as the Advisor attempted to turn the wheel (q3). Long story short: problem was a rusted/rotted out ground wire (q1)! Behind the front driver side tire, encased in a boot. Tech told the Advisor he'd never seen that one before. $40 part, and $400 to install it (q4). I was happy it wasn't a power steering rack failure (electric) but the more I thought about it, felt I needed to report this. You needed a dealer scanner to catch this and trace it to a ground fault. Probably better for you to contact dealer Advisor and Tech to get a better breakdown on this (q1). Dealer was great, they could have sold me an $1800 steering rack and I'd have never known. Could this failure have happened to someone driving on the street and this pop up all of a sudden (q2)? I believe so. Glad I didn't find out firsthand. The problem went away overnight twice, and then all of a sudden your wheel is LOCKED. I'm curious as to if others are or have faced this, thus my submittal. Thanks for your time.

THIS IS A RECALL REMEDY FAILURE REPORT UNDER 49 U.S.C. §30120. My 2020 Chevrolet Silverado 1500 (VIN: [XXX] ) received Recall 24V797000 on June 9, 2025. The ECM update is intended to detect incipient clutch-pressure or gear-ratio deviations—early signs of a developing slip—and automatically force limp mode to prevent rear-wheel lockup. On August 23, 2025, after the recall was performed, the truck experienced rear-wheel lockup at highway speed. Limp mode did not activate, which shows the recall remedy failed to operate as required. Mangino Chevrolet documented symptoms matching the recall defect, including abnormal ratio behavior. No metal debris was found in the pan, indicating the failure was not caused by wear. GM TAC also noted behavior consistent with a developing slip. GM first recommended full transmission replacement at my expense before acknowledging the recall. GM later authorized a valve-body replacement, which also failed. The dealership owner provided a written statement confirming that: (1) the recall remedy did not correct the defect, and (2) the valve-body repair did not correct it. On December 3, 2025, GM Customer Assistance attempted to close my case as “not recall-related,” despite the post-remedy lockup, limp-mode failure, dealer findings, and the written admission that the recall remedy was ineffective. The safety defect persists after recall completion, and GM has not provided a remedy that corrects it, as required under federal law. I am reporting this as a failed recall remedy and an ongoing safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

During driving at low speed 15-30mph with 4 wheel drive set to auto. 4 wheel drive engaged and rear wheels locked up. Turned off 4wd no issue. Upon arrival at the dealer a bad sensor was determined to have caused the rear wheels to not perform as designed. After resolving the issue now I hear rubbing metal noise from the drive shaft. Spoke to Chevy about the issue haven’t heard back.

SERVICE BRAKES, VEHICLE SPEED CONTROL
My truck started acting sluggish like the parking brake was applied while driving. At a traffic light I put the vehicle in park applied and released the parking brake. I put the vehicle back in gear an let off the brake. The vehicle did not move so slightly pressed the accelerator. The vehicle still acted as if the brakes were applied. I could feel the slight movement and torque being applied but only slightly lurching. The traffic light turned green so I proceeded up to 45mph. A vehicle in front of me slowed to make a turn. Applied the brakes and nothing happened. I pressed the brake so hard that I lifted myself off the seat. I swerved to miss the vehicle avoiding a collision. Then warnings started popping up; "brake system failure max speed 62mph", "brake system failure max speed 42mph", Brake system failure", service traction control", "service trailer baking system". among others I was too busy to see all of them. I coasted to a stop in a nearby parking lot with visual and audible warnings still going. I shut the vehicle off then restarted it. Some warnings remained like traction control and the engine light. The vehicle appeared to be operating correctly so I drove it to a local dealer. they said there was a code for low voltage in the brake control module but couldn't get me an appointment for over two weeks. I took the vehicle to a regular mechanic who said what I described was impossible. That mechanic kept my truck for the balance of the day but could find nothing wrong. I no longer trust this vehicles brake system. In many scenarios the failure, were it to happen again could be catastrophic.

ENGINE
What component or system failed or malfunctioned, and is it available for inspection upon request? Based on information from ODI Resume EA25007 & Safety Recall N252494002, it is more than likely engine connecting rod bearing failure. How was your safety or the safety of others put at risk? I was traveling at freeway speed, 70mph when it occurred. Has the problem been reproduced or confirmed by a dealer or independent service center? 11/25/25 at 12:33 (pacific), I am currently stranded 190 miles from home and waiting for the truck to be towed to the dealer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It has not. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Prior to Failure: Since I’ve owned the vehicle, I’ve notice slight ticking and slight knocking during cold start within the engine bay. At the time the noises seemed normal and not cause-for-concern. At Time of Failure: I was traveling on level grade on the highway when I heard a deep knock from the front, bottom left side of the engine bay. Within about a minute from the initial noise, I received a “check engine” warning light and a message of “ESC Warning” displayed on my instrument cluster. At that moment, I noticed the engine noise become more prevalent and constant. I immediately slowed and coasted to my next exit off the freeway.

The transmission quite working while I was driving down the road. Took my foot off of the gas pedal and my truck bogged down completely and had no power to it. It is at an auto repair shop so I am unaware if it could be inspected under request. Took time but was able to safely get off the roadway and out of traffic. It did the out of no where. Started having some issues this summer but no warnings lights ever came on, so I didn’t think much about it. Completely stopped in the middle of the road and had little to no power from the transmission to the truck to move off of the road. My truck is currently in an auto repair shop waiting on a new transmission to be installed. I had it towed to an independent auto shop from where it stalled. There were not warning lamps or anything at the time of my transmission quitting. Truck started to run rough and shifting hard this summer but without warning lamps I didn’t take it anywhere. When running on the interstate it was shuttering which I thought was due to possible tire out of balance. It would also hesitate to take off when put into drive. It had several of the same issues that Chevy had on other transmissions that were recalled within this same time frame.

Ever since I bought the truck I have had a issue with the transmission after it heats up an around 57mph the transmission is stuttering like crazy fluids an filters has been changed an no change on the transmission operation. After talking to many shops states that my year model a style of truck has terrible transmissions this is a safety issue that needs to be looked in to.
