When shifting into park and attempting to turn off the car, 80% of the time the vehicle would not register that the car was in park and allow the vehicle to turn off. It would alarm & charm with a message to "shift to park". this is a known manufacturing issues with the Chevrolet Traverse, GMC acadias, and possibly other models of Chevy/GMC. This is a major safety concern as there is no way to know if the vehicle is truly in park and can leave you in scary situations when you cannot turn off the car. We have also been stranded with a dead battery because the "shift to park" chime and message drained the battery. Chevrolet has provided their dealerships with bulletins in how to add a jumper harness and add/replace a switch in the gear shift assembly to correct the issue, but refuse to take accountability. I have had multiple service advisors admit they have had to fix numerous gear shifters and that this is a known issue. A recall needs to be issued on this problem as it is a safety concern for anyone affected. Please address! I am including my receipt on the service I had to pay for to fix this problem. Also an example of one of the technical bulletins Chevrolet has sent their service department.

Shortly after purchase, my car would not acknowledge being put in park. I would shift the control to park but would get warnings park was not engaged. I took it in for repair. Now I am getting a message to service parking brake. This seems to be a problem with this vehicle. I do not use the parking brake, so I can't understand why service is needed. Both problems were when car was in park. The 'service parking brake' warning stays on while driving.

Bought 2018 new. Two days after driving off lot passenger seat melted electrical connection causing seat failure. GM fixed four days later driver seat same thing. Week later headlight connection melted and had to be fixed spent a week in shop. Started claim at GM to take car back after a month of run around and stalling they offered me $250 in accessories and dropped the problem as it is all fixed under warranty. The diagnostic block under the dash melted so they couldn't use it and had to be replaced. Most recent the left brake light failed and it was because the connection melted and the light had to be replaced. A week after that I was driving on I75 and heard an explosion and the right brake light was blown out of the car. I took it to the dealer and he connection was melted and the car has been in the shop since 29 Sept 20 and today is 7 oct20 the car has only 21700 miles on it. I have again called GM and started again that this electrical problem is dangerous as those lights are led low voltage so what is causing this surge of high voltage and no answer. All repair records are at the dealer and this is not normal to have 6 electrical issues in two years but GM has decided to look the other way. It's been a week since calling GM and I have not gotten this resolved as yet.

Auto will not shut off when put in park. Message indicates 'put in park'. tried several times. Engine will go off, electronics stay on. Would drain battery if left on. Also, bluetooth continues to disconnect. Brakes squeak constantly, from the time it was driven off the lot. Car stutters when you attempt to accelerate. Car has been to dealer many times, supposedly 'fixed'. I was told to try higher octane gas. This should not be necessary. Electrical problems are increasing. We have purchased several Chevrolet, this is the absolute worst vehicle as far as problems which, after 2-1/2 years, have not been repaired. Why is there not a recall"?" car is currently at the dealer, again.

I had purchase a 2018 Chevy Traverse from curry Chevrolet in the same year, I notice a little slipping with a little jerking sometimes a few months later and the shift to park was acting up. I called curry and asked them is there any problems or recalls with this model, service dept said no, then I had called a deferent dealership they said the same, and I had call curry about three times regarding my this problem, so I kept checking my VIN# on Chevy.com nothing comes up. So I went on line to find out I wasn't alone regarding these problems even with later models. Then I called customer care twice to make sure the info I was giving was the same, I had explained my problems with them, she said there are no recalls under my VIN# at this time, I went over my warranty with both customer reps, both were accurate that my vehicle is still covered. I also received info there is a bulletin out #18-na-121. I am hoping there wont be any problems correcting these issues, I am prepared for a fight getting a lawyer and going to many news stations, I don't understand why would you put a defective part not only in my model but others with out solving the problems first according to other owners that had posted the same problems with the powertrain. I am truly disappointed with Chevrolet, and to think I left Ford & Dodge.

Power steering failed on vehicle while in motion. Electric power steering module failed causing extreme difficulty getting the vehicle parked. Steering rack had to be replaced and computer re-programmed. Vehicle is back at the dealer with a similar trouble code for a follow up to the original repair. It took GM over 4 months to get the replacement part making us drive our vehicle with a faulty steering rack never once providing a loaner vehicle or buyback opportunity.

When you put the car in park and go to shift it off the car doesn't senses that it's parked. Will not shut off completely and can't lock or arm car. Restarted car several times and still signals the car is not in park.

- Hyattsville, MD, USA

Shift to park error message while the vehicle is in park. This prevents turning the vechicle off, locking the doors, etc. This problem has been well documented on several thousand vehicles. However, GM has only quietly fixed problem case by case and will not cover under power train warranty. A national recall should be issued asap to fix and replace the shifter. Poses a safety issue as well since it involves a faulty gear shifter.

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.

For the past several months we have been having difficulty turning off the engine, with an error warning us to 'shift to park', when it is already in park position. This renders the driver unable to turn off the vehicle and will lead to battery drain. We brought the vehicle once again to lucas Chevrolet service department on December 31st to fix this and were made aware that this is a known problem, not yet at the recall level. It has now been a month since the service department ordered the part needed to make the repair, assuming they even know what that is. This is absolutely unacceptable considering we were told the part would be delivered in just a few days.

First issue is, when you stop driving the Traverse, place it in park and hit the button to turn off the engine, it will shut off the engine but not the electronics. The car displays "action required shift to park" even though it is already in park with the red P lit up. You cannot turn off the vehicle until you repeatedly start the vehicle, place it in drive then back to park. Eventually it will work correctly. Vehicle will not lock when this happens. This now happens every time I try to turn off the vehicle. I am just out of warranty and dealership says I need to replace the entire steering column as the recommended fix from manufacturer did not work. All of which are out of pocket expenses despite this being a well known issue. Also, vehicle will randomly have a long delay before the vehicle shifts in gear. You shift to D and hit the gas and the engine revs like it is in neutral and eventually it will finally start to go. This delay with engine revving also happens randomly when at a stop and accelerating through intersections and I have had a few near misses of almost being hit because of this! this second issue only seems to happen when going from a stop.

I was stopped at an intersection and the transmission did not allow the vehicle to move forward, it appeared to disengage even though the shifter and dash icon were set in "drive" mode. There is also an alarm sounding when I shut the vehicle motor off and the dash screen reads "shift to park". I found that I need to restart the vehicle and shift out and back in to "park" in order for this alarm to shut off. It appears there is a bad connection between the computer and the transmission or visa versa. GM has already issued several tsbs related to this vehicle as you might be aware.

On October 1, 2018 I purchased a new Traverse from kelley Chevrolet of fort wayne Indiana. My question is can the auto stop on my new 2018 Chevrolet Traverse be disabled. I just had a close call involving the auto stop. I was in branson mo on vacation and this place is built on hills and more hills. I had come to a stop on a hillside and the car went to auto stop. When I lifted my foot on the brake so auto stop would not be engaged the engine stopped. I had no brakes or steering of the vehicle and it started rolling backward ' thank goodness there were no cars behind me. The vehicle was rolling toward a very steep hill on the side of the road and with no brakes I could not stop. Instead I pulled hard on the steering wheel and got it crosswise stopped in the middle of the road. It took me several times before I could get the engine started. Auto stop is a pain in the butt and this scared the dickens out of me. Can it be reprogrammed to not work?

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.

When I attempt to turn my vehicle off, I get a message on the screen that says to put the car in park. I verified that the car is in park and the screen reads that it is. The message continues, and the vehicle will not allow me to shut anything off or lock the vehicle. The vehicle just continues to chime. The only recourse is to disconnect the battery. But then, I cannot lock the vehicle. I have included a picture of the screen to show what I am seeing. I have seen several issues online regarding GM vehicles with this issue. I was told by the dealership, who has left me stranded without a car, that they have seen this but there are not enough issues out there to warrant a recall. It would seem to me that this is a safety issue that should require immediate attention.

- Cortlandt Manor, NY, USA

Multiple instances have occurred where entertainment system and other areas of dash randomly shutdown while driving. Music can not be played, turn signal sounds are no longer heard, and voice operations do not work. Turning car on and off does not solve problem, however after sitting over night seems to work normal. Most recent two instances happened September 14th, 2019 and September 8th, 2019 so just a week apart.

- Aurora, IL, USA

Began 6/19, with progressive worsening. When the vehicle is placed into park and shut-off, a warning appears on the info display stating" shift to park". at which point the vehicle keeps all lights on the inside and outside of the vehicle illuminated, the ac stays on, the radio/entertainment display stays on, in addition to a warning beep/chime that is typical when the vehicle is left "on" and you open the door. In other words, our vehicle still thinks it is "on" and "in" gear. In the beginning it would take 2-5 times of turning the vehicle back on and off in order for the warning to go away and the vehicle to shut-off properly. Now, it will no longer shut-off regardless of how many times the engine is restarted and the stick-shift is moved out of park & back. Have resorted to unplugging the battery every time we exit the vehicle to keep it from being drained. The vehicle has also not re-started at all(taking 15 minutes of re-engaging the starter button at its worst). Leaving my wife & toddlers stuck in 100plus degree heat. When it does not re-start, the dash display reads the vehicle at "0 mph" and allows the gears to be shifted. There are numerous other people online stating similar issues. Some have resolved with a change of the shifter mechanism, & others still with continued issues after that. The dealership stated there is only 1 part left in town, and that it is on back-order and they can't get it from the manufacturer(they tried their two nationwide warehouse locations). Not only that, the dealership said we needed to leave the vehicle with them and they would not even "look at it" for up to 1.5 weeks, and that they were out of loaner vehicles. The vehicle is still under warranty, and was purchased certified-used. Nothing has occurred while driving the vehicle or when stopped at a light/stop-sign, but we certainly don't want to find out what "could" happen.

Vehicle starts intermittently and once started it will run for a while, then engine will turn off, all power steering, brakes etc will not work. Tried jumping the vehicle and would not power cycle.

When I stop driving and put in park warning comes up on display "shift to park" it takes a little bit to get it to turn off, but if you dont see it you could have dead battery when get back in car.. this should be a recall, getting tired of always reshifting it every time I turn car off,
