2008 Chevrolet Impala Problems

Transmission Pressure Control Solenoid Failure May Cause Erratic Shifting

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

oil pressure sensor

The engine light was on and the car seemed to be running fine. That is when i went in to hook it up to the diagnostic machine. We found out it was the oil pressure sensor. You do have to order the part through GM, but it is only $10.00. my husband fixed it in about 10 min.

Plugged Catalytic Converter May Cause Loss of Engine Power

The catalytic converter may become plugged resulting in loss of engine power. General Motors has extended the catalytic convertor warranty on some models to 10 years or 120,000 miles. Please contact your local GM dealer to see if your vehicle is included.

2008 Chevrolet Impala Recalls

Ignition Lock Cylinder Concern

Excess weight on the key ring can cause the ignition switch to move out of the run position without warning, turning off the engine. This defect can also affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. Dealers will install two 13mm key rings and key insert into the vehicle's ignition keys to correct this concern.

The Front Control Arms May Break on Impala Police Vehicles

On vehicles equipped with the "police" option package, one or both of the front lower control arms may fracture. A broken control arm can result in the loss of control of the vehicle, increasing the risk of a crash. Dealers will replace both front lower control arms to correct this concern. The General Motors recall number is 12104.

2008 Chevrolet Impala Reviews

I bought this car new. Now has 60k miles on it, & it has been FLAWLESS ! I wouldn't even think about getting a Toyota again, after the crappy one I had before this car.
It's a good car but minor problems with heating system that does not work properly during automatic starting mode.
Bought 2 2008 Impala LT's this past November. Both were used........23k miles. Excellent Condition. Both wife and I have only one complaint and that is for a car with a cabin so spacious........very few storage areas. No drink holders in the rear. Interior cabin lights seem to be lacking. Other than that...we love both cars. I installed a K&N Airfilter on both are we are now averaging 34m...
