The Kunes GM dealership in Lake Geneva used their best certified mechanic and he screwed up tightening the seal cover, so I had to come back in September to get the stupid mechanic to tighten the seal cover on drive train shaft correctly. Next, I tell him the power steering fluid is making a noise when turning. Probably low fluid. The car runs great except for these minor things.

Had car in for alternator light/low power mode.. Had accelerator pedal sensor replaced, then mechanic noted leaking with differential pinion seal. It's expensive, under warranty, but dealerships in metro Detroit will not provide loaners so I had a private mechanic fix it ... apparently a 4 hour job.

Possibly dangerous if fluid leaks out.. possibly problems with awd? Good luck...
