Numerous electrical problems with this car from the beginning. Within the first year of ownership, had to replace the window motor for the passenger side window. At less than 4 years of ownership, have replaced the battery twice, due to interior and dashboard lights that stay on and drain the battery. At about 60,000 miles, the left blinker came on continuously and stayed on, draining the car's battery. I had to disable the turn signals entirely, and now have to signal with my arm out the window. It will be over $1,000 to replace the body control module to fix the problem with the turn signal. The motor for the passenger side window is also broken again. If the motor for the driver side window goes, I will be unable to signal turns.
Since we purchased this vehicle new we have replaced the battery twice, the clutch, fly wheel, slave cylinder,three times, a coolant leak fixed, the window motor and it is currently at the repair shop. We also have had to replace all four tires and have the vehicle aligned. The air bag light is also on at this time. The thing that makes me angry is that a service technician has seen or vehicle twice and said our vehicle was fine. So, why did the clutch go out 10 days later?.
