| Ignition Coils Failure problems |
Engine ignition coils fail due to cracks and corrosion. The car will not exceed @ 20 mph, thus putting the occupants at risk. This is a problem other Porsche owners have also experienced. Porsche replaced 6 coils on my vehicle all identical to the original units which failed. Thus the vehicle will again fail in traffic.
