CHEVROLET Complaints

Summary of Incident: On March 28, 2026, while traveling at 70 MPH on the Florida Turnpike, the vehicle suffered an instantaneous loss of motive power. The engine died abruptly with no warning. Upon reaching the shoulder, the electronic transmission locked, refusing to shift into Neutral or Park. The engine cranks but will not start. 1. Component Failure & Availability: The exact component is currently unknown, but the failure involves the Powertrain, Fuel System, and Electronic Transmission Control. The vehicle is currently at an authorized dealership and is available for inspection by the manufacturer or NHTSA upon request. 2. Safety Risk: The sudden loss of power at highway speeds created an immediate risk of a rear-end collision. Because the electronic transmission locked and would not allow the vehicle to be shifted into Neutral, it became a fixed object on a high-speed shoulder. It could not be pushed to a safer location, increasing the risk of a secondary accident. 3. Problem Reproduction: The vehicle was towed directly to an authorized Chevrolet dealership. As of this filing, the dealership is in possession of the vehicle, but the failure has not yet been reproduced or confirmed by a technician as they are awaiting formal diagnostic commencement. 4. Inspections: The vehicle was inspected by a roadside towing professional for transport. It is currently at the manufacturer’s authorized service center awaiting a formal diagnostic inspection. No police or insurance inspections have occurred. 5. Warning Symptoms: There were no warning lamps, "Check Engine" lights, or messages prior to the failure. No symptoms like rough idling or unusual noises occurred. The vehicle performed normally until the moment of total power loss.

Steering wheel does not return to center, requiring driver input to do so. Force needed to turn the steering wheel continued to increase throughout the past year, getting abnormally difficult and unlike any other vehicle. Had the steering rack replaced, which corrected the problem.

On February 23, 2026, while driving my 2026 Chevrolet Equinox EV home from Folsom Chevrolet following a prior repair visit, the “Service Park Assist System” warning illuminated, first intermittently, then after a few miles, continuously for the remainder of the 11-mile drive home. During the same drive, while reversing with no objects present behind or around the vehicle, the automatic emergency braking system activated and applied the brakes with significant force without cause. The vehicle was returned to Folsom Chevrolet (Repair Order #559378, opened February 23, 2026). Diagnostic code U1126 was found — indicating the left rear short range radar sensor had lost communication on CAN Bus 8. The sensor module was on national backorder, keeping the vehicle out of service for approximately two weeks. The module was replaced and programmed on March 7, 2026. Safety concern: Unexpected activation of automatic emergency braking with no objects present creates a serious collision risk from following traffic. This failure occurred on public roads during normal driving. Additionally, the U1126 CAN bus communication fault is the same vehicle communication architecture implicated in the battery/electrical failure documented in Repair Orders #558923 and #559167, suggesting these failures share a common root cause in the vehicle’s electrical communication network rather than representing isolated component failures.

Incident Date: February 10, 2026 Mileage: 1,260 On the morning of February 10, 2026, my 2026 Chevrolet Equinox EV (1,260 miles) would not start. The instrument cluster simultaneously displayed three warning messages: 1)“Service Battery Fault — Vehicle Won’t Restart,” 2)“Charging is unavailable,” and 3)“Charge Vehicle Soon.” The vehicle could not be placed in neutral and required dolly tow from my garage, as the front wheels were locked and could not roll freely. AAA and I measured the 12V battery at 11.8 volts. AAA technician made attempt to jump 12 volt battery with no success. He made the observation that it was very rare for an EV not to start once the 12 volt battery was jumped. The vehicle was towed to Folsom Chevrolet (Repair Order #558923, opened February 10, 2026). The technician performed a global reset, BECM reprogramming, standalone radio programming, and a manual reset procedure. The repair order was closed with “confirmed no further concerns,” however the root cause — identified in the repair notes as a possible HV module communication fault — was never confirmed diagnosed or repaired. Seven days later (February 17, 2026, RO #559167), the vehicle returned to the dealer with overnight 12V voltage loss, starting at 12.12V and continuing to drop. A parasitic draw test found an 11mA draw. After a second overnight test the dealer closed the repair order as “no concerns found” without identifying or repairing a root cause. Safety concern: A vehicle that cannot be started, cannot be charged, and cannot be placed in neutral poses a serious safety risk — particularly if such a failure occurs on a roadway rather than in a driveway. The inability to shift to neutral prevents the driver from clearing the vehicle from traffic. The root cause of this dual electrical failure has never been confirmed repaired despite two repair attempts.

The Transmission on my truck down shifted and made it so I lost all power while driving. If I would have been on the freeway it probably would have killed me or caused a serious accident. It is at a shop waiting to be inspected but they said it was the valve body in the transmission. No warning lights came on at all, and the shop had to plug a computer into my transmission to get the codes. GM needs to make this right because it is going to kill someone or cause harm if a bad accident happens due to failure at freeway speeds.

Recall/Loss of Power I am filing a safety complaint regarding a 2023 Chevy Equinox. The vehicle began losing engine power and will not go over 40 mph. This creates a dangerous driving situation because the vehicle cannot maintain highway speed. The vehicle has a fuel system recall, and the issue appears to be related to the fuel system. The vehicle is currently at a Chevrolet dealership and has been there for almost a month. The vehicle is currently inoperable. This is a safety concern because loss of engine power while driving could cause an accident. I am requesting that this issue be investigated as a safety defect. Sincerely, [XXX]   VIN [XXX] Mileage: 63,000 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1) The engine failed and lost propulsion while driving. It is currently at the dealership where I purchased the vehicle new, so it may be available for inspection upon request. 2) My safety was put at risk because the vehicle lost propulsion while driving. This is a dangerous situation in general. In my case I was able to pull over safely and have it towed to the dealership. 3) The problem is that the engine failed. This can be confirmed by the dealership. 4) This 6.2L engine was part of the N252494001 recall for specifically the issue of engine failure and loss of propulsion, so it had been inspected by the dealership recently. I brought the vehicle into the dealership for this recall several months ago. Per the recall, they told me that the engine would need to be replaced if it didn't pass the inspection. They performed a Pico test, informed me that it passed the test, and changed the oil to 0W-40. It has not been inspected by GM, the police, insurance representatives or others at this time. 5) There were no warning lamps, messages or other symptoms of the problem prior to the failure.

The Powersteering is failing in my 2011 Chevrolet Malibu with 93K miles on it. The warning light on the dashboard appears randomly then it becomes difficult to steer. This has become a safety issue because when driving on the highway or trying to navigate turns requires a lot of strength and can be a hazard while driving in traffic or alone. I have taken the vehicle to an auto repair shop for a diagnostic and they were unable to fix it due to the Chevrolet dealership who no longer makes the part. I have researched and found that GM had a special coverage 15356 for this problem but no recall. The special coverage is now expired. I am not sure if it has been inspected by the manufacturer as I am the 2nd owner. The message that appears on the dashboard when there is a loss of power steering says ESC Power steering then it becomes difficult to steer. The problem started about 1 month ago.
