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 constant velocity (CV) boots and CV joints should be inspected at each service. Servicing the torn CV boots early can prevent the need to replace the CV half shaft or CV joint.
A normal operating clock may cause the airbag warning lamp to illuminate or a chronic dead battery.
The front hood and rear deck lid support struts may fail; replacement is required.
Engine issues related to valve guide wear are common. Oil consumption, smoking at first startup, and valve train noise are all symptomatic of loose guides and worn valve stems. The valve train is complex and should be thoroughly inspected if a problem arises.
An accumulation of small air leaks at various locations around the intake manifold/intercooler area can cause performance problems.
Abnormal noises from the intermediate shaft area may be signs of impending engine failure, don't wait to get this issue checked out!
Various repairs and adjustments to the drive mechanism (including cables) are commonly needed on the Cabriolet tops.
Ports and passages for secondary air flow can clog at the cylinder head/cam housing area. Partial engine disassembly may be required to fix the problem.
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.
If engine misfiring, rough running, or fuel consumption issues are not resolved quickly, the catalytic converter can overheat and fail.
Climate control modules can be problematic. Symptoms vary but include failure or persistent dead battery after not using the vehicle for a while.
