On Wed., Dec. 6 around 3:15 pm during heavy traffic on FWY [XXX], cars slowed down to a brief complete stop. When I went to start slowly as traffic began to move, engine completely shut down. I could not open windows or my door to get out of vehicle. Immediately called 911 and was transferred to DPS. It took approximately 65 minutes before I had help and was finally towed from the dangerous freeway lane where I was stuck and with vehicle completely stalled and locked down, I couldn't even get car in N to be able to have help moving to a non dangerous place outside of the FWY lanes. This is the fifth time this car locks down. I've learned to open a panel by the foot brake area, pull a lever in that area and be able to move the car to a safe location until I got towed into the dealer. It is the second time that this has happened in a potentially dangerous street and now Freeway. Danger to myself and many others that had to maneuver around me. The first time (around 2020) the car totally shut down, it was reported that a computer harness had to be replaced. This last time I was faced with such a dangerous situation on a FWY it was determined that the ECM (Engine Control Module) had caused the shutdown and locked the vehicle to where I could not even get out for close to an hour. The ECM was replaced by GM and the car is running again, but my shock and trauma still haunt me as to the self and others danger that was present. . GMC Dealer finally determined after several attempts that ECM was the problem. Unsure if available to inspect it. Delivered car back 12/8. . Heavy freeway traffic at peak hour put me and many others in serious danger. . My dealer report reads it was difficult to diagnose and finally find ECM was the problem. .Vehicle has not been inspected by Manufacturer, police, or insurance. .A few minutes before this lock-down an engine icon appeared while on the FWY. Previous shutdown incidents had no warnings or messages before locking up. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFO

Driving 2,5 hrs from Binghamton, NY towards Long Island on Saturday. We took a short break and after that I got onto the highway and not even hit the 50 miles/hour speed I received “engine power reduce” alert on the dashboard and car stalled. I was able to pull the car off the road. I was provided a tow truck by the state police and moved to closest GMC service, GRAND PRİZE GMC Nanuet, NY. This car has only 30,309 miles and it’s 2018. The car has been fixed by replacing 5 parts, oxygen sensor, pcv tube, air inlet tube etc. We ended up paying $1,460 just before the Holidays. Rightfully, we are very upset with this unexpected event driving a basically brand new car, in 30000 miles. This car has been mostly driven by my wife who is in 60s in local streets not exposed to harsh enviroments. There is a recall I noticed online for 2019 models and almost from the same area of throttle body, but nothing for 2018. Now, my wife and I hesitating to drive the car. Are we going to get stuck on the road again?

I have a 2018 GMC TERRAIN which I bought brand new from General Motors. In May 2022, the vehicle started jerking/hoping and trying to stall when the speed gets to 55 miles per hour or higher. I have taken it to the dealership on three different occasions for repair and I still have this issue. General Motors engineers were involved in every step of the repairs. They just do not know what is going on with the car or fix it and they are too stubborn. The dealership told me today that they cannot do anything else to the car. They also said they had a code from the engine last week and General Motors said they do not know what that code means. They are forcing me to accept/drive the car in this unsafe condition. I have contacted them multiple times and they do not care.
