The electronic level ride system may not work properly; this may result in the rear of the vehicle riding too high or too low. Our technicians tell us that a height sensor or exhaust valve failure are common issues with this system. Proper diagnoses will be necessary to confirm the exact fault.Google+

my 1990 Cadillac Deville Coupe's rear end drops down after about 10 minutes of driving. I have 20 inch rims on it so that is a problem because the tires rub. i put on new shocks thinking that was the problem, for the most part its fixed but say when i drive up a steep hill and the back end drops below a certian point the back end wont level back up to where it should be

Vehicle seldom used to transport passengers. First noticed when two persons, with baggage, was being transported to Airport, noticed vehicle ride was exceptionally rough and very low in the rear, barely clearing the ground.
It continued to sit low but ride improved when passengers were dropped. A check with the Cadillac Dealer quoted an outrageous price to diagnose the problem, therefore, no repair or diagnosis were ever done to date. Vehicle has only 72,000 miles.
