Buick Regal Problems
RepairPal has identified the most common problems with the 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 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.
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 power window motors and switches are prone to failure.
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.
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 external engine oil leak. The manifold gasket will need to be replaced to correct this issue.
The 2011-2013 Buick Regal is known to have issues with the EVAP system, a part of your emission control system.
To correct the issue, the EVAP canister vent valve, solenoid, and wiring must be inspected. The most common fix is replacement of the wiring connector or replacement of the vent valve 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.
