2018 Chevrolet Traverse service brakes problems

“I was driving along the Jackie Robinson Parkway when, on a curve, the car braked on its own and crashed into a wall, resulting in the total destruction of the vehicle. My son had to be hospitalized. This car had braked on its own before—at speeds of 10 or 15 mph—but I didn’t think much of it at the time; however, this time we were traveling at 45 mph when the”

“On 08/15/26, I was at a traffic light waiting to make a left turn on a major roadway. Because the wait was on a hill, the park brake automatically engaged. When the traffic light turned green and as I attempted to accelerate, the electronic parking brake failed to release as it should and normally does. Since the vehicle would not move normally, I was unable to safely make my intended left turn so I had to continue straight in order to get out of the way of moving traffic. As I was driving to a parking lot of a business in the vicinity, my back tires were screeching and smoking as the park brake appeared to remain engaged. I was extremely concerned because I was in active traffic and could not operate the vehicle normally. I attempted to resolve the problem by turning the vehicle off, allowing it to sit for a few minutes and restarting it. After at least 20 tries, I could feel the pressure of the brakes release and I was finally able to move the vehicle normally. This was frightening and placed me and other motorists at risk. I was stopped at a major intersection on a hill when the vehicle failed to operate normally as traffic began moving. Had the parking…”

“The vacuum pump had a catastrophic failure. This led to failure of assisted breaking, and caused brake pedal to go rock hard while driving on the roadway. Metal shards from the vacuum pump broke off, and has now entered the engine. Chevy knows this vacuum pump is flawed, but did not include my model of vehicle in the recall. Even though it uses the same part. I received a “brake assist” message on the dash about 15 seconds prior to the loss of brakes. I had my wife and two kids with me, and this jeopardized their safety. Further research on the matter states this is a known issue at GM, but for some reason my year and model were not included.”

“The contact owns a 2018 Chevrolet Traverse. The contact stated that the driveway was on a slope, and his wife was attempting to reenter the vehicle while it was in parked and the engine was running, and in the process the vehicle began to roll forward down the contacts driveway, the contacts wife was injured in the process receiving bruises to her left leg and right hip, medical attention was required for the contacts injuries. The vehicle was brought to a stop upon crashing into a lawn mower trailer and the contact's garage with the vehicle's front passenger side quarter panel. Property damage was reported. The vehicle was going 5 MPH at the time of the crash. The contact confirmed that after the incident, the vehicle was still in the parked position after the crash. The vehicle was not towed. No warning lights were illuminated. A police report was not filed. The vehicle was not destroyed. The local dealer was contacted, however the vehicle was not diagnosed. The manufacturer was not notified of the failure. The approximate failure mileage was 107,000.”

“The E Brake engaged while driving our car, by the time we could safely stop our vehicle, less than a mile, the transmission fluid reached 175 degrees and our vehicle was smoking. We took the traverse to a local service center, they stated this has been a known issue with the make and model of our car. There is a service bulletin about this issue. The brake actuator is faulty, and allows water to seep into the actuator creating a short to ground the electric park brake actuator.”

“For the past 3 years my 2018 Traverse will randomly say shift to park and won't let me turn my vehicle off even though I am in park. In the last week it has gotten worse happening almost every time I drive it and not recognizing that I am in park for anywhere from 2-10 minutes.”
