Porsche 911 Problems
RepairPal has identified the most common problems with the Porsche 911 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The ignition distributor's internal drive belt can fail and cause misfires and performance problems. After being updated, the distributor belt requires regular inspection.
Pay close attention to warning lights and have the brakes inspected regularly—immediately address any brake problems. Hard driving habits will cause excessive brake pad and rotor wear. Aged brake fluid can cause numerous problems, including "waxy" buildup visible in the reservoir, so replace the brake fluid regularly. Special procedures are required to bleed/flush ABS pump.
The hydraulic pump relay can fail, causing the pump to run continuously, which leads to hydraulic pump failure due to overheating. Incorrect pressures will cause a low brake pedal or a high pedal effort with the possibility of other strange symptoms.
An external fluid leak may develop at the pressure switch; fluid will be evident in the trunk and the reservoir level will drop.
The brake warning display and warning gong can activate, typically after the first start of the day. The warning light/gong might stop after idling for a short time. This fault is usually caused by low stored hydraulic pressure due to a failed high pressure accumulator.
