 This Sentra has been towed to the shop 7 times, starting at 5000 miles.  The throttle sensor went bad 3 times, finally requiring a complete ECM, throttle body, and wiring harness.  Then at 35000 miles it started blowing the ECM fuse.  It has been very intermittent, now it is getting another ECM and a complete wiring harness and dash electronics.  I'm not sure what the instrument panel has to do with the problem, but just today Nissan agreed to cover it under warranty even tho the car has 40000 miles on it.  The initial repair was around $2000, this estimate is $2700.  Very expensive for a $15k car.  Needless to say, this will be my last Nissan.
