2000 Pontiac Grand Prix GTP Problems
RepairPal has identified the most common problems with the 2000 Pontiac Grand Prix GTP based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The high pressure power steering hose will commonly leak fluid; it should be replaced.
One or more of the power windows may stop working due to a failed window switch. Failed switches will require replacement.
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.
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 crankshaft position sensor, ignition module, and/or powertrain control module (PCM) may fail resulting in illumination of the Check Engine Light with ignition system related fault codes stored in the PCM. Patience is necessary when dealing with this specific situation as normal diagnostic procedures are not effective. In many cases, the best option is to replace parts, one at a time until the fault is corrected.
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 intake manifold gasket may develop external engine oil leak. The manifold gasket will need to be replaced to correct this issue. RepairPal cannot confirm a recall for this concern on these models.
