I have a 2019 Blazer. A beautiful car but it began to malfunction at 9000 miles. Reduced engine power causing the car to stall - very dangerous. After a total of 48 days in the shop I have my car back. The dealer replaced the ECM (engine control module) the gas pedal assembly and some faulty wiring. I’m honestly nervous to drive it. Anyone had their ECM replaced and if so how’s the car doing now?
