“The power transistor on this car is prone to failure. This results in the engine shutting off completely, leaving the driver with no power, greatly reduced steering and braking, making the car hard to control. A real hazard during merging into high speed traffic and in cornering. The company had a voluntary program to replace these, but the redesigned part also fails. In my case it only lasted 15,000 miles!”
