problem #3

Impala SD V6

  • Automatic transmission
  • 73,000 miles

Service stabilitator traction control is the message that I am getting on the dash. Then it flashes to Engine Power Reduced. This has just happened this week and I am trying to figure out what to do about it. The first time the message appeared on the dashboard, I was driving around in town. I thought that the car might die and I had someone check it out. I found out later that if I just wait awhile and restart it that it seems to be OK. The second time that the message came on was in the pouring down rain on the interstate. I put on my emergency flashing yellow lights and continued to drive until I made it home. I took the closer exit than I would normally take to get home so that I would not be on the interstate. I am still trying to figure out what to do about this situation.

Impala SS 5.3L

  • Automatic transmission
  • 100,000 miles

A year before this issue we replaced the computer at a cost of $700. A year later same problem. Stabilitrack and traction control lights come on. Engine light flashes. Car misses and transmission shifts rough. This is random. Motor still has a lot of power. We have spent over $700 on this in the last 2 years trying to find the problem. Chevrolet wants $100 to diagnose. Then you have to repair right then or they will charge you $100 if you have to come back. We have replaced all kinds of things thinking it was fixed. Only to drive it a few miles and the same problems start again. Gas mileage is awful when this is going on. We love our car but this is getting truly ridiculous!

Chevrolet replaced computer at a cost of $700! Not a very old car to need a computer!
