On two separate occasions the engine shut off at low speeds and the emergency brake engaged. On both occasions there was no warning of any kind. The car restarted and ran fine until shortly after the first two instances a ‘low voltage’ light illuminated prompting me to research and learn that the shut off problem is well known. I took it to the dealer who confirmed the issue and assured me it was fixed with a software update. Two weeks after the ‘repair’ I was driving at highway speeds and the ‘low voltage’ light illuminated and the car shut off and the emergency brake engaged. After I managed to get off the road it would not restart. It was towed to the dealership who kept it for 2 1/2 months. This time they replaced the MGU. I picked it up and less than a week later the ‘check engine’ light illuminated. I returned it to the dealership who confirmed it’s the same issue. To date the manufacturer is unwilling to acknowledge the problem or help. I was informed today that it was ‘fixed’ (this time ‘battery pack’) but I’m afraid to drive it after my life was placed in danger after two ‘fixes’. It has been in their possession for over 3 months and it would be illogical to believe they understand the root cause and that the issue is truly fixed. I will not drive it until I’m assured it is safe as I don’t want to put myself or other lives in danger. They appear to be guessing at the cause and at best replacing parts with the same flawed parts into the same flawed design and are unwilling to accept responsibility. This vehicle is dangerous.
