My exhaust system warning light just came on. :anger: Seems to be driving OK. I guess I'll take it in tomorrow to see if they can figure out what the problem is. Anyone else have this happen??

You mean the 'engine' lamp for which the manual says check exhaust etc? This lights when the exhaust gases are not normal. Cause: anything that may affect the combustion procedure. Mine turned on once, after dealer washed the engine with pressurized water and shorted the ignition plugs. At idle, do you see unburned fuel dripping off the exhaust pipe?

Did you have oil changed or added oil recently? Overfilling may cause this. Bad quality fuel might also foul the sensors.

My opinion? Verify that your car is hasn't lost water or oil and drive the shortest distance possible directly towards dealership. Do not increase rpm beyond 2,500-3000 I would say.

Keep us posted.
