Turbocharger is defective. Reduced engine power. Engine Power reduced shows up on my dashboard. I bought the car brand new at Lindsey Buick in Ohio. This car is too young for this problem. Lindsey Buick and GM need to stand up to accountability and transparency when it comes to delivering top quality products. My vehicle almost caused a horrific accident by not accelerating fast enough. I am [XXX] , a widow, and in need of my car being fixed.

I was definitely put in danger as I was driving at rush hour in a 6 lane busy US 1 Federal Highway. The vehicle was stalled, without any power, in the middle lane with cars and trucks swerving around me at the last minute. I called 911 immediately and they dispatched cruisers to help push my vehicle across 4 lanes of traffic. This meant having to block 4 lanes of moving traffic. It was a long 10 minutes of waiting as angry drivers were leaning on their horns in frustration. AAA flatbed towed my vehicle to a near mechanic's shop, but it was after hours and had to be left there until morning. The mechanic inspected the problem and confirmed the issue was a fuel module and fuel pump failure. How does this happen without any alerts to the driver? How can you prepare a driver of such a serious engine failure putting that drive...
