vehicle will randomly lose all throttle power when driving and at the same time following a warning beep will flash a large red lightning bolt with the following messages: service electronic throttle control,stop/start unavailable service stop/start system, service electronic stability control and check engine light. Engine continues to run but car will not move. Once vehicle is able to be pulled over to the side of the road and turned off then cranked back up the vehicle will drive normally. Check engine light will stay on for several key cycles then it will eventually go away. This has happened at intersections and at speed on the interstate. Repair of this issue with the vehicle has been attempted 4 times and is currently at the dealership now for the 5th time and the diagnosis is that they can replace the throttle module but there are not codes pointing to that as the issue and it was stated that is is just a guess and I can then drive it and hope that it is repaired. The vehicle has been to two different dealerships for the issue as the 4th occurrence was too far away from home to get it back and it was only 319 miles between failures. The issue has not been taken seriously by the dealerships nor the customer care agents that have been contacted through the last 3 occurrences. The agent has been helpful in getting a rental or loaner to drive and delivering my vehicle back but the gravity of the problem has not been fully grasped by those examining the vehicle. The only reason this has not resulted in a crash is that each time it has occurred a space to get off the road was accessible. This will not be the case if the vehicle is continued to be driven. I did continue to drive the vehicle with the hope that the repairs would have been adequate to prevent the issue from reoccurring. This issue began in september 2024 at 30k with most recent 5th time noted below.
