NHTSA Complaint #11707183 — 2024 ALFA ROMEO TONALE

The car engine and hybrid system shuts down randomly and without warning when I am driving, and the car has no power. The first time it happened was on Wednesday, Dec. 11th 2025. I had just picked up the car a few days prior, when they replaced the high voltage generator under warranty. I was on the highway and the car shut down, with a red turtle on the right side of the instrument display. I rolled to a stop on the shoulder and managed to get it running again. I drove it in E-SAVE mode for about 40 miles and it shut down again, and I rolled to a stop on the side of the road. I got it restarted and in E-SAVE mode I managed to get it to the dealer. It was returned to me on Wednesday, Dec. 17. The dealer, Ron Lewis Alfa Romeo, said it was not programmed properly after installing the part on the prior repair job. They claimed to have driven it 50 miles without issue after the reprogramming, and said it was fixed to good working order. Today (Dec. 26th, 2025) I was going up a hill and it shut down again, with a red turtle on the dash, and the car stopped. I got it started and drove it home in E-Save mode. I then had Alfa Romeo roadside assistance have the car towed back to Ron Lewis Alfa Romeo. The car is unsafe and I cannot drive it without fear of it shutting down while underway. Having a car engine and hybrid system completely shut down in live traffic, either on the highway or in a suburban or business district, suddenly and without warning is incredibly dangerous to the driver, passengers and those in other vehicles. They have been unable to find and fix the problem, and keep giving me back an unsafe car to drive.
