The car went into limp mode while I was on the highway. The car said reducing engine power and then I couldn't go the speed limit I had to drive well under the speed limit and pull off the road as soon as possible.

While driving my 2022 1.5L Turbo GMC Terrain at 65 mph with the air temperature at -2 degrees below zero Fahrenheit the check engine light came on with the error message "Engine Power is reduced." I coasted to the side of the road and put the car into park. I was 200 miles from home and after working with my insurance roadside assistance, I wasn't able to get a tow truck after 3 hours of waiting in sub zero temperatures. I called the local GM dealership in my home town to ask if I could drive the SUV and they said I could at less than 35mph. I drove 100 miles to a town where a tow truck was available. I brought the SUV to the GM dealership and they said the issue is ice and condensation in the inner cooler CAC system. They said my SUV wasn't updated for the cold weather package. I was told my engine needed a cold weather package in order to drive it in sub zero temperatures. After reviewing this issue online, I found there was a recall for 2018-2022 1.5L Turbo GMC Terrain vehicles that experience these issues but my VIN number wasn't included in the recall. I called GMC to report the issue with my SUV and after speaking with multiple people was told that it wouldn't be covered under the recall due to the "numerous factors" that determine what VIN numbers fall into a recall. My SUV has the same engine, is the correct year, and has the same engine problem as the GMC Terrains that were included in the recall. I now have to pay out of pocket for repairs and the engine fix of installing a cold weather package that is covered under the recall. I believe the recall needs to be expanded to additional VIN numbers.
On Aug 3rd 2023 I was driving east on a Michigan Highway when the service transmission warning came across the dash then the car shut off while driving 60mph. When trying to steer the car to the side of the road I noticed the car was in park(this car is equipped with push button shift). The car shutting off made it very hard to steer. If the traffic was heavy this could have caused an accident. I do have a video of this happening
Leased a 2002 GMC Terrain/Denali on 12/30/2022. 34 miles on car. Loved driving it. I have put on additional 210 miles. On 01/20/2023 after dropping a 'CT' disc at my Oncologist I got back in car and was driving home. Still love my car. In doctor's parking lot the 'Parking' light would not go out when put in reverse. Same issue two times until I went into drive and car moved a bit. Then reverse, all ok. At stop light just beyond MD office I turned left. Initially I crossed intersection (yellow engine light went on) and gave gas pedal a push to go 45 MPH (legal speed on a 2 lane West bound). Two lanes on opposite side head East. All of the sudden foot still on gas speed drops to 25 MPH but Tachometer now reads 4000! Scared looking rear view mirror and 3-4 cars behind close to my bumper now and before slowing down hit their bakes. I being panicked took foot of gas and tried to go slowly forward again to get out of way. Same issue with 25 MPH only and now tachometer reading between 3500-4000. Really panicked as those 45 MPH (or more) cars slammed on their brakes. Were not so nice, but of course! Now went to side of road and stopped. Waited a couple of minutes started again but went no more than 25 MPH with a burning smell. Got to a parking lot and hit 'SOS'. 2 sets of 2 hours each no tow arrived. Talked to 'SOS' a number of times. Finally called wife she behind me with flashers and me with flashers drove home. No more than 20-25 MPH. Tow arrived and driver could not get car in reverse so pushed into street in our complex. Finally pushed enough to use winch to get car aboard. Took to dealer in FT Lauderdale (Sheehan) been there one week today and thy called at 5:00PM car finished. Admits transmission problem. Me what could I do? Dealer says to pick car up. One week for repair of this brand new car? My wife is petrified as to what happened. Doesn't want to take a chance to ride in it. Scary ride that day for certain. This all seems so one sided to me. That hurts.
