Powertrain malfunction, 2022 GT

[wilbur5k]

I was driving my 2022 Corsair GT (18k miles) to the Atlanta airport on the freeway with my adult daughter to pick up family yesterday afternoon when I suddenly lost power. The car was still driving, but slowing down. Pushing on the accelerator did nothing. The ICE had been running mostly using my normal "conserve" mode, having used up up full battery charge on the first leg of my trip to a distant appointment. Fortunately I was able to get over to the right lane and get off at exit, then was able pull off the road.

 

The dash error message said something like "Get service soon" with a wrench icon. The phone app showed "Powertrain malfunction/reduced speed." It also showed a second fault was "service engine soon." After shutting off and restarting, I switched to Excite mode and it seemed to run the engine and drive, so I headed back home on surface streets, having the relative at the airport rent a car.

 

After driving a few minutes of the now-90-minute trip home, the failure happened again, slowing me to maybe 15-20mph. I managed to get to a small park parking lot and tried to get a Lincoln concierge tow. The app indicated they would arrive at 1030pm (5 hours!). Fortunately my daughter has AAA and got a tow truck in 40 minutes, and we got an uber quickly for the 40 minute freeway trip home. AAA dropped my Corsair at my Lincoln dealer which happenef to be pretty close by.

 

So what the heck happened with my car? A loaner isn't available for a month! The failure wsrning detail is "powertrain or AWD/4WD drive fault. Contact dealer asap." The service engine warning detail was "...issue with engine will cause reduced power. If not repaired soon may damage engine." This sounds like a catastrophic failure. Could have been even worse if I hadnt been able to get off the freeway safely.

The lincoln dealer's service agent says they diagnosed and solved the problem. That's great if it is true, since my appointment wasn't until Monday. But it doesn't make a lot of sense. They say the problem was that 2 extra quarts of oil had been added, presumably at the last oil change (in January!). So they removed the excess oil and now problem is supposedly solved. I'll pick it up in the morning.  It is a little hard to believe it will be fixed, but I hope they are right!
