2012 Porsche 911 Problems

Pay close attention to warning lights and have the brakes inspected regularly—immediately address any brake problems.

The accumulation of moisture at major connectors and control units can cause various ABS/PDAS faults due to corrosion.

The brake warning display and warning gong can activate, typically after the first start of the day.

An internal transmission problem can cause difficulty engaging or downshifting from second gear.

Ring and pinion failure can occur on 4WD versions.

The release mechanism for the clutch (including the release arm bearings and shaft) can fail and cause stiff, binding, and possibly noisy pedal operation.

A normal operating clock may cause the airbag warning lamp to illuminate or a chronic dead battery.

Using the wrong battery or the failure of a climate control module may cause a chronic dead battery after the vehicle has not been used for a while.

The vehicle central warning display can be sensitive to interference from vehicle ignition faults such as high voltage arcing anywhere in system.

Smoke, oil consumption, and fuel trim issues with various fault codes can be traced to an internal leak at the oil separator.

A small leak in the coolant reservoir can cause persistent coolant loss.

Engine oil leaks can occur at the rear main seal and/or intermediate support cover o-ring; a revised seal is available.

Due to air leaks at various locations, the Check Engine Light may illuminate.

Check Engine Light illumination and performance issues can be caused by oxygen sensor faults.

Various fuel trim and oxygen sensor limit fault codes can be traced to an internal vacuum leak at the oil separator.

The front hood and rear deck lid support struts may fail; replacement is required.

Wind noise at the front of the car and water leaks at the vent wing are typical problems on Targa models.

Creaking noises while driving over bumps and when cornering may be difficult to diagnose, but are usually caused by the windshield at the body/seal area.

Fluid leaks at the right rear corner can often be traced to the radial seal at the power steering pump.

In order to avoid ABS, Tiptronic, or intermediate differential faults/warning lights, correct tire profile and wear must be maintained.

The front control arms should be regularly inspected for wear at the ball joints and bushings.
