2021 CHEVROLET SUBURBAN Complaints

Vehicle stalled while driving in center lane on I-4 in Orlando in traffic. There were no warnings prior to the vehicle stalling. When trying to restart it, the low fuel warning appeared along with the check engine light. I was unable to restart the vehicle leaving us stranded in the middle lane of I-4 in heavy traffic. FL Road Rangers arrived to offer aid and had to manually place the vehicle in Neutral under the vehicle at the transmission. Vehicle was then pushed off the highway onto the shoulder. Vehicle was towed to Starling Chevrolet which was the closest Chevrolet dealer from the incident. Starling's Service Department had to replace the battery in order to run a diagnostic. Once the battery was replace, the diagnostic indicated that the issue is with the Fuel Pump Power Control Module Part No. 13544060 / 13554821. This part is on back order with no known availability time provided. Vehicle is still sitting at Starling Chevrolet. Although my vehicle does not show any open recalls, I found that the fuel pump power control module for the 2021 Chevrolet Suburban is part of a known Product Safety Recall N212332040 Stall While Driving.

The fuel pump power control module caused the fuel pump to fail and resulted in unexpected engine stall. The issue cause me and my 4 children to be stuck in the middle of the road waiting for a tow truck for over 3 hours. The vehicle could only be put in neutral while the car was on. Since I couldn’t start my car I could not put it in neutral to move the vehicle out of 2 way traffic. We want the issue confirmed by the dealership but the police who aided me and my children inspected the vehicle and recommend getting the fuel pump look at. No warnings were displayed.

Fuel pump incident identified in recall N212332040. NHTSA says our 2021 Suburban was not involved in the recall. But the incident happened 3 separate times. Our dealer made the repair under warranty.

While night driving driver noticed the driver side headlight completly pointing down providing no visibility. Vehicle was brought into GM dealership where is was discovered the Driver LED headlight adjuster screw broken causing a safety issue, where the light beam pointed down. Vehicle light assembly is currently being inspected for replacement under manufacture warranty under 36,000 miles.

The contact owns a 2021 Chevrolet Suburban. The contact stated while driving approximately 35 MPH, the engine started to misfire, and the vehicle lost motive power. The contact stated that the check engine and other unknown warning lights were illuminated. The contact was able to drive the vehicle to a dealer who diagnosed the vehicle and determined that the lifters had collapsed. The lifters were replaced on only one side of the engine. The vehicle was repaired. The contact stated that the failure recurred one week after the repair. The manufacturer had been informed of the failure. The failure mileage was 36,126.

The computer component surged, and the vehicle is available for inspection. The vehicle brake function is lost. Stepping on the brake paddle did not apply brake. Brake function was disabled by the computer. I took the vehicle to dealer, they said it was a component that has high resistance that cause it. But not sure why it has high resistance at that time and the resistance is gone after driver restarted the vehicle. No one else inspected the component beside the dealership. There was no warning at all and this is the first time it happens. Driver was just driving normally and suddenly all the light in the instructment panel started blinking and driver tried to apply brake but nothing happen. Luckly it wasn't rush hour, and driver was able to let the vehicle roll to the freeway exit on ram and use the up ram to slow the vehicle until it almost stop and changed gear to Park to stop the vehicle. Driver then restarted the vehicle and the problem is gone.

Second row drivers side seat headrest latching mechanism failed. The head rest will not stay in the upright position and is a safety hazard if someone is sitting in the seat as it hits the passenger in the back of the neck.

The contact owns a 2021 Chevrolet Suburban. The contact stated that while driving at 25 MPH, the brake pedal seized while depressed, and the vehicle failed to stop immediately. The check engine warning light was illuminated, and "Brake System Failure" and another unknown message were displayed. The contact coasted to the shoulder of the road and parked the vehicle before shutting off. The contact's husband then restarted the vehicle and drove to the residence while the vehicle made an abnormal grinding sound when the brake pedal was depressed. The vehicle was taken to the dealer, where it was diagnosed that the master brake cylinder needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 30,000.

While driving on the I-4 interstate on Saturday August 5, 2023 - my 2021 Cheverolet Surburban stalled as if it had no fuel (had 3/4 of a tank). I was barely able to get over to the shoulder across three lanes of traffic on an overpass before it completely shut off! The Surburban would not start - when pressing the start button the ignition clicked for an extended period of time. We used On Star to contact GM/Chevy roadside support. They ran a remote diagnostic stating an issue with the Fuel Management System. I was told that this is a common problem with the fuel pump failure. I see there are open recalls for many other GM vehicles but not for my VIN currently. My Surburban has 40,669 miles. We waited over 3 hours for the tow truck that was dispatched by GM/Chevy. We were not in a safe location. Turns out my Surburban cannot be placed in neutral without the vehicle being started, which means it had to be dragged on and off the tow bed. I had to pay $450 to have it towed to my my home town dealer as we were 90 miles from home. We were originally going to tow it to a local dealer when the Surburban stalled but they told me not to as they are backed up and could even look at it for 9 days. I am now waiting on word from my dealer. Clearly the recall needs to be expanded based upon what we are finding online and from what everyone is telling us locally.

Engine stalled while driving on middle of the highway, lucky i was able to pull over to the breakdown lane by putting vehicle in neutral. I had reported the issue to the Chevrolet Onstar roadside assistance but while trying to get tow truck I had tried to start the engine multiple times and finally it started and left the engine light on dashboard. It was really scary with my kids in vehicle. Chevrolet should really look into this issue. My vehicle less than couple of year old and has only 16k miles.
