My engine light is on and this is the 15th time I have bought my car in for various engine problems like engine power reduced and other problems with this car. The car would just stop in the middle of the ride or jerking as I drive it. I have been on the highway when it has stalled before as I drive. I have had these problems since I purchased the car in 2018

What 2018 Cadillac Ct6 Plug-In Hybrid owners say
Most recent owner complaints, unedited.
Loss of all vehicle power while traveling on the freeway at highway speeds. Vehicle check engine, power limited, and electric motor overheat warning lights come on. The combustion engine will not start, and battery power availability goes to zero. This is very dangerous to public health and safety due to instantaneous loss of combustion engine and electric battery power while in fast-moving highway traffic. There are several instances of this same problem occurring in many cadillac owners forums, so general motors knows there is a problem with their ct6 phev transmissions. The fix seems to be replacing the transmission due to a bad clutch pack, but people could get hurt if this issue is allowed to continue without a permanent solution.
Right after purchase, the nav screen kept flickering, causing a distracted driver situation and a hazard. The dealer did everything they could per gm guidelines, but even after the 1st service visit, the car would shut down in drive mode, as the vehicle was in motion. Then the vehicle would not shut off using the power off button. Gm is telling the dealer, the nav flickering screen is not a safety hazard, however I beg to differ if every 2 mins, a driver is fixated, focused on the screen more so than on the road, which has caused me to run off the road a few times. This is a serious safety hazard and electrical concern that gm does not seem to care about even after 60+ days at the dealership.
