2018 Chevrolet Express Problems

While travelling down the road the "service Stabilitrak" and "service traction control" messages come on in the Driver Information Center and the lights for each component are lit in the dashboard. On occasion, the emergency brake light comes when I know the emergency brake is off. My safety is at risk because I'm not sure if the lights are indicating a problem or if the lights are malfunctioning as they come on every time I take a trip in this vehicle. The vehicle has been inspected by three different Chevrolet dealers, one of them three times and no fix has solved the problem. The dealers confirm the problem, but cannot find the solution. Chevrolet headquarters is well aware of the issue and have paid toward some of the dealer charges. The issue has been going since I purchased the vehicle in 2019.

The contact owns a 2018 Chevrolet Express. The contact stated that the defroster would intermittently fail to operate as needed. The contact mentioned that the defroster might start working when driving over a pothole or an obstruction in the road. Upon investigation, the contact linked the failure to NHTSA Campaign Number: 18V655000 (Electrical System). The contact also discovered that the rear window was made out of tempered glass which failed to comply with FMVSS standards; she was also able to link that failure to NHTSA Campaign Number: 19V387000 (Visibility). The manufacturer was notified of both failures and informed her that the recall repair for NHTSA Campaign Number: 18V655000 (Electrical System) was already performed on the vehicle. The manufacturer also informed her that the VIN was no longer included in NHTSA Campaign Number: 18V655000 (Electrical System). The contact was also referred to the dealer, but they offered no assistance. The vehicle had yet to be repaired. The failure mileage was approximately 60,000.

The transmission started to fail at around 65k miles. There were no warning signs, it just began shifting hard and then began slipping. It was taken to a transmission shop and the fluids were replaced, but this did not change anything. It was at this time we were told the transmission would need to be replaced, but they had no means to obtain a replacement. It has been over two years since the problems started and the transmission is still in the vehicle and we drive it daily. It continues to slip going up through the gears and progressively gets worse during the day. By the end of the day you cannot pull out in front of anyone for fear of it slipping and not grabbing the next gear. This is an obvious danger to us and other drivers around us. The problem has been evaluated by the Chevrolet dealer and two other independent shops. The fluids have been changed but this did not help. Only the dealer has been able to provide a solution which is to replace the transmission. This was quoted to cost $11,000. Due to this high price and no alternative options, we've continued to drive the vehicle as safely as possible.

when the vehicle approaches 45-50 mph on the highway, the car begins to shake violently, where it feels like the body/frame of the vehicle is going to separate from the car. the only way to resolve/reset this is to bring the vehicle to an almost complete stop and then re-accelerate. when this happens on the highway everyone violently shakes in the vehicle, and it is difficult to quickly bring the car to a halt as other cars are traveling at highway speeds behind the vehicle. this has been taken to the dealership multiple times over the years with no resolution.

ALSO, WHILE DRIVING, THE REAR BRAKE LIGHTS REMAINED ILLUMINATED WHEN THE BRAKE PEDAL WAS NOT BEING DEPRESSED.

THE FAILURE MILEAGE WAS 7,200.

TL* THE CONTACT OWNS A 2018 CHEVROLET EXPRESS. WHILE DRIVING APPROXIMATELY 35 MPH, THE BRAKES APPLIED AUTOMATICALLY. TO KEEP THE VEHICLE FROM STOPPING ABRUPTLY, THE CONTACT DEPRESSED THE ACCELERATOR PEDAL TO CONTINUE DRIVING. IN ADDITION, THE BRAKE INDICATOR ILLUMINATED DURING THE FAILURE. THE FAILURE RECURRED AND THE VEHICLE WAS TAKEN TO THREE DIFFERENT DEALERS, INCLUDING EMICH CHEVROLET (303-647-5376, LOCATED AT 2033 S WADSWORTH BLVD, LAKEWOOD, CO 80227) TO BE DIAGNOSED, BUT THE FAILURE COULD NOT BE DUPLICATED. THE CONTACT WAS INFORMED BY THE TECHNICIAN THAT THE VEHICLE PERFORMED AS DESIGNED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 7,283. *BF

The contact owns a 2018 Chevrolet Express. The contact stated that the gear shifter would shake when shifting gears. Over time, the shifter cable fractured without warning. Due to the failure, the contact had the vehicle towed to a dealer where he was informed that the steering column needed to be replaced. The contact disputed the diagnosis and notified the manufacturer of the failure. The manufacturer initially agreed to repair the gear shifter under warranty; however, they later informed him that they would only cover 10% of the cost for the repair. The contact was provided with a case number. The contact then had the vehicle towed to Ourisman Chevrolet Buick GMC of Alexandria (1800 Old Richmond Hwy, Alexandria, VA 22303) where he was charged for the repair to the shifter cable. The vehicle was repaired. The failure mileage was approximately 70,000.

Since purchasing this vehicle in 2018 we have had an ongoing issue of the car randomly going into a violent shaking when exceeding speeds of about 60mph, it happens without warning, and other than coming to an almost standstill, it is impossible to recover the vehicle. This is extremely dangerous on the freeway. Have taken the vehicle to Chevrolet dealership multiple times without any resolution. They would charge us for an alignment and this never fixed the problem. This continues to be an ongoing issue, and now having researched it on the internet, I am reading this is not a unique experience by Chevrolet/GM truck owners.
