I was driving on the freeway then my car suddenly started slowing down. I tried changing lane so i can pull over on the side of the freeway but unfortunately i couldn't get to pull over before the car completely stopped on the freeway. I called AAA. They sent a tow truck which came to the freeway to tow my car. My husband came and took me to work. The car was towed to a GMC dealership. I went to the dealership after work. I was told my car has timing chain problem and if not fixed will damage the engine. I went online to read reviews of this car only to see it was a very common problem for this year and model of GMC which if i have ever read those reviews i would not have bought a GMC. This vehicle should be recalled for this issue.

Accordingly, the said vehicle first manifested a dangerous defect issue on July 14, 2021, while traveling out of town. A significant and abrupt reduction of power completely disabled the vehicle while parking in a parking space .Despite several attempts, the vehicle still fail to start. Only to notice the engine light illuminating and flashing repeatedly. At the same time the dashboard indicated a faulty reading of fuel and oil. This is a very serious and frightened situation because I received absolutely no warning before the vehicle shut down. Without reason of doubt, I do believe it is unsafe, extremely dangerous and is potentially a hazardous situation that should be investigated. Fortunately, I was in a parking lot went the problem occurred. Whereas, if the vehicle engine stopped abruptly in the mist of traffic it could have resulted with a different outcome. On July 16th the vehicle was towed to a certified GMC dealership for further inspection. Hours later, I received the service contract and a follow up call from the dealership given that the diagnostic is the Engine Control Module (ECM) and needs to be replaced. Surprisingly, to my dismay I was advised that General Motors no longer make the part and the Service Center is not sure when and if the part will be available. As of today, July 26th, no one has taken the necessary steps to remediate my situation. I have already attempted to resolve this problem by contacting the Manufacturer directly. Yet, no information on when a resolution will be made. I have been a loyal customer for several years and currently seeking answers.

The car shutters intermediately when driven at higher posted speed limits. From about 40/45 miles per hour up to about 60 miles an hour. The vibration shakes the entire vehicle. Letting off the gas or acceleration will stop it, but go back to a steady speed, and it returns. Have kept up with service and the vehicle is in tremendous condition, but this condition is present in all weather and temperatures and seems to not have a cure. Have replaced all possible causes, including torque converter and possible sensors. Has not gone away. Noted that other owners have posted similar/same complaints on the same year and make. Same complaint with sister car 2011 saturn outlook. There is a problem with the drive train and needs to be fixed. Understand some people have found a damaged "d plate" in the transmission-but replacing the part has resulted in the part failing again and the problem returns.
