Broken Head Bolts

The Carrera 911’s exhaust studs are located in the cylinder heads and have a habit of breaking and must be replaced. This is caused by the head bolts being impaired repeatedly by heat coming from the engine’s exhaust system.

Coolant Leaks

This is a well-known problem caused by corrosion. Many owners have reported coolant leaks in the lower half of the expansion tank on older models.

Engine Defects

Engine defects are a significant problem in models produced between 1990 and 2004. One Carrera owner said they experienced a catastrophic engine failure caused by the timing chain coming off and destroying the entire engine which had to be replaced. In 2005, the Carrera 911 was overhauled in order to correct this problem.

Porsche Boxster

Between 1997 and 2005, the Porsche Boxster had many reports of failure to the intermediate shaft bearing or IMS bearing. When the IMS bearing fails, it leaves metal debris throughout the engine which would need to be completely rebuilt or replaced entirely.

Unusual Tyre Wear

Some drivers have reported early or uneven tyre wear on Boxsters caused by misalignment. The tyres seem to appear worn on the inside and outside edges instead of straight across. This is an important sign that the car needs a wheel alignment.

Electric Roof Issues

There have been reports of intermittent faults with the electric roof. The roof seems to jam halfway up. The problem could be due to bad or degraded connections at a number of different points.

Porsche Cayenne

Owners have reported that Cayenne’s cooling system overheats and the plastic tubes melt and burst. This issue can be prevented by upgrading the pipes from plastic to aluminum.

The sounds come from under the dash of your car. The best option is to have this issue checked and repaired by a qualified mechanic.

Porsche Panamera

Porsche reported 14,571 recalls in China caused by defective camshaft adjusters. The recalled cars included several imported Panamera models produced from April 2009 to Sept 2011. On some models, the bolt on the camshaft adjusters became loose or broke. The only remedy is replacing the part.

Defective Radiator Pump

On several forums, many drivers reported a defective radiator pump. One driver said his 2012 Panamera’s radiator pump just quit after only driving 28,000 miles.
