2000 Chevrolet Impala Problems
RepairPal has identified the most common problems with the 2000 Chevrolet Impala based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The intake manifold gasket can develop external engine oil or coolant leaks. In some cases the failed gasket will leak coolant internally. The manifold gasket will need to be replaced to correct this issue.
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.
The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault.
The high pressure power steering hose will commonly leak fluid; it should be replaced.
The serpentine belt tensioner pulley may wear out. Our technicians tell us that in order to get a new pulley from General Motors you must purchase a complete belt tensioner assembly.
The engine may start and stall with the security light flashing. This is commonly caused by a failed passlock sensor which is part of the ignition lock cylinder. A secondary cause could be the ignition switch itself. Worn contacts inside the ignition switch can cause voltage drop issues which can affect the passlock system. Proper diagnoses should be performed before replacing any parts.
