Hi, What was the issue with the car shutting itself down while driving? I have a CTS and having the same issue.Report it
So, it's been more than two months since the last repair on this car, and it's safe to say that repairs have been sufficient. There has been no 'limp mode' shutdown of the engine while driving since the ECM, throttle body and wiring harness were replaced and wired correctly. I have also replaced the pressure cap on the coolant recovery tank. So far, this car is running as I expected when I first bought it, and I'm starting to really like it. For those who may be looking into this year model as a purchase, please be aware that there is a chance you will have to repair the throttle body as well as the ECM--you can't just do one or the other because it's best to replace both at the same time, because they have to be programmed for your car. This car entails some expensive repairs so do your research on it before you buy it. The '03 model will allow you to check for fault codes, but all other models require a scanner that you attach to the vehicle.Report it
emcculland...well, after numerous trips to the dealership--8 since my purchase in January--it was determined that the ECM and the throttle body both needed to be replaced. The dealership replaced both and reprogrammed, at a cost of nearly $1800. Now, the last time it caused problems after the parts were replaced, the same problems had returned. It showed symptoms of hard shifting, so I drove slower to avoid the car going into 'limp mode'. When the car was sent back to the dealership, they checked the wiring harness--which they had replaced when they replaced the throttle body. They determined that the wiring was not getting a significant connection through the crimp connectors, so they removed those and hard-wired everything. So far, so good. But now I'm trying to determine another issue with the coolant recovery tank.Report it
