Hello everyone:) always a pleasure to come visit. Thank you all in advance for helping me out with yet another problem with my 2006 LT. So now this is what my HHR is doing. When I start it, there is no traction control light. If I either let it sit idling, or if I am stopped in traffic for too long, the traction control light comes on. When this happens, the transmission hard shifts. I have to shut the car off and restart. When I restart the car, the traction control light goes out. Then the car runs and drives fine. But man if I let it idle in my driveway for more than 5 minutes that pesky traction control light comes back on. Any ideas? In order for me to keep the traction control light out, I need to keep the car in motion. Very strange phenomena and I have no idea why on Earth this would be going on. Any help would be greatly appreciated :-)
