Parking brake wouldn't release. Service parking brake light on. I had parked on a slight hill. After about two hours, I started my vehicle, pressed the button, shifted to reverse, and the vehicle wouldn't move. Odd! I looked at the cluster and noticed the 'park' flashing and the service parking break light on. I tried shifting in and out of park to drive or reverse multiple times and each time pushing the button. No luck. I left my vehicle at the location since it was late and safe. The next morning before having it towed, I tried once more to push the parking brake button and it successfully disengaged the parking brake and the service light cleared itself. I noticed on a forum that 2018 Traverses have this issue and disconnecting the battery or letting it sit for a few hours sometimes resolves this recurring issue but never fixes it.

Export version only. Country: Colombia. 1. shitf to park. When you park the vehicle ask you to put it in park and it is already. Dealer is working on that as I write this thread. Tech found a recall or bulletin from manufacturer to repair or possible replacement of some parts 2. service stabilitrack. In many and ramdom ocacions this service light comes on and 20 seconds later goes off. When stopping at a light. Dealer unable to duplicate and no fix yet 3. fuel economy system, it does not work right now, and it happened twice before. Does not turn off when you stop at a traffic light. Delaer has updated software in order to remedy this issue. 4. locking audio confirmation. When you manually lock the doors it gives you an audio or lights confirmation. It does not work any more. Dealer looking into this issue. 5. electric parking brake. The electric parking brake activated it self while driving in traffic. Heavy traffic situation 5 mph and the E. brake came on and stayed on. The vehicle did not move forward or backwards. Turn the engine off several times, put in parking, neutral etc etc. After 5 minutes of blocking traffic had to force the vehicle to the shoulder. Almost did not make it. Turn vehicle off and called the flat bed. While waiting 15-20 minutes later turn vehicle on and surprise!!! it was fixed. Magic. The E brake was off and the vehicle was free. While this was going on the E brake light (red) was on, and service parking brake light (amber) was flasing all the time. Dealer did an update to the system and not sure if it will happened again. But this is the third time this happened. Once at my house about six months ago but it took about 1 minute and it fix it self so I did not pay attention to it. The second time it happened to my wife at a shopping center but she left it in the lot and went back shopping and when it came out it was fixed.

Vehicle was stopped on a steep city street behind another vehicle turning left. Vehicle went to move forward and turn left and it shut off and rolled backwards down the steep hill. Wheel could not be turned, brakes could not be pressed, when gas was pressed it did not go forward, it rolled backwards it was like it shut off after being in auto stop mode. Parking brake assist came on automatically and vehicle rolled into a cement pole. Vehicle was able to be restarted. Parking brake would not release. Had to shut off vehicle, restart and tried to release parking brake 5 more times before it released. This vehicle often rolls backwards after being in auto stop mode and the gas needs to be pushed hard in order for it to go forward. This vehicle feels like it slows down when pressing the gas at times and you need to push the gas pedal harder. The brakes squeak often when wet and cold and sometimes when starting the vehicle the brake will not allow you to push it down, you have to push it several times, let up and push it again before the vehicle will start.

Car had about 10000 miles and in two separate occasions has stalled, steering wheel had stop working, couldn't steer, car turns off when stopped at traffic lights, alrms go off and dealer just says they can only reprogram the computer, no repairs available. On a third time braking system alarms went off and dealer had to replace the braking system. Vehicle has always failed while in motion. Dealer and manufacturer will be responsible if someone gets hurt because this car does not function as it should.

Drove it and within 2 days while restarting the vehicle, the engine light was back on again. Drove it over the weekend and returned to the dealer at 438 miles and the power brake booster was replaced. Have had no issues after this was done regarding the brakes.

After about 1000 miles the brakes started grinding, and alert would pop up to service them and they would be a heavy vibration as the antilock brakes would be kicking in even at very low speed's. I brought the vehicle back to the dealership where they replaced all of the brake sensors, after another two weeks it started happening again they replaced the wiring harness because they said it had a short in it. Both times I was told the parts on national backorder which led me to believe this is a large problem. It has now happened the third and fourth time but I have not had time to bring it back to the dealership. I lost almost 2 weeks of having the car in the first two months that I've owned it. It now has 3500 miles on it. The problem is happening at 5 mph and even on the highway every time the brakes were touched
