2001 Buick Regal Problems
RepairPal has identified the most common problems with the 2001 Buick Regal based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.
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 display on the heater and AC control panel may become dim or go completely blank. Our technicians tell us the control panel must be replaced to correct this fault.
One or more of the power windows may stop working due to a failed window switch. Failed switches will require replacement.
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 intake manifold gasket may develop external engine oil leak. The manifold gasket will need to be replaced to correct this issue.
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 high pressure power steering hose will commonly leak fluid; it should be replaced.
