A/C was cutting in and out, took car to the dealer. During the checkout they also found, in addition to the compressor bad, a leak in water pump and right catalytic converter plugged. All items, beyond normal oil change, etc, was covered by the extended warranty (that my wife said I should not have taken) that resulted in (repair less warranty cost) a savings of over $500.00!

I have a 2011 Buick Lacrosse with a problem that the local dealership can't seem to diagnose and fix. I have left the car at the dealership several times without a remedy for the following problem. Intermittently, when trying to start the car the dash will indicate "no remote detected" and the car will not start. Sometime after 10 or 15 seconds the car will start, and if not, I depress the open and lock buttons on the remote and the car will start. If this fails, I place the remote in the pocket beneath the cup holders and the car starts. This problem is starting to occur with more frequency, roughly 5 or 6 times a week. I am afraid that at some point, I will not be able to start the car.
