Porsche 944 Problems
RepairPal has identified the most common problems with the Porsche 944 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Due to a failed resistor pack, the HVAC fan may only operate on the high speed setting.
Suspension components (including control arms, boots, and ball joints) are critical and require regular inspection.
Aged brake fluid can cause numerous problems and should be replaced regularly.
Corrosion/moisture at the throttle position sensor can cause performance issues relating to low boost.
Engine shut down or a "No Start" may be caused by cracks at the DME (fuel pump) relay solder joints. Repairing or replacing the failed relay should correct this concern.
Air leaks at the manifold gaskets can cause engine misfire (especially at idle) or black smoke under load.
Due to a broken plastic link at the servo motor for the heater control flap, the interior temperature can become wildly erratic.
In automatic transmissions, the flexible hub at the engine flywheel may deteriorate and fail, causing a large amount of play in the driveline. This failure may be caused by prolonged engine oil leaks.
The driveshaft bearings on higher mileage vehicles may become noisy.
The front hood and rear deck lid support struts may fail; replacement is required.
