Engine check light came on and we were told that nothing was wrong and it was reset. the second time the check engine light came on, the co2 sensor was replaced. the third time was the same day it was repaired for the 2nd time and the check engine light came on 20 miles later. the oxygen sensor was replaced again. in addition, the ignition & fuel injection fault tracing was found faulty. they also found that the mass air flow meter was faulty & had to be replaced, we've had problems with the air conditioner which has a constant ticking sound that they claim is normal for this model. the convertible top had to adjusted and the dashboard also has had to be remounted 3 times. this car has been tied up at the dealer for 40 days because of the check engine light that keeps coming on and we've been told not to worry about this. *ak
