Cadillac XTS rear shock absorbers not rising when starting the vehicle on Cadillac XTS

Some Cadillac XTS owners report experiencing issues with the rear shock absorbers not rising when starting the vehicle, which may indicate that the rear air suspension has failed. Symptoms of this problem include the car "crouching" forward when stopping, the rear end lifting while the front nose dives, or sagging on one corner or an entire side. Common issues reported include the air suspension failing to raise, low ride height, air compressor failure, and receiving a Service Leveling System warning message. Additionally, some owners notice the vehicle leaning to one side, sagging in the rear, a noisy compressor under the hood, or a slight "nose dive" when stopping. It is advisable for owners experiencing these symptoms to have the air suspension system inspected by a qualified mechanic for proper diagnosis and resolution.
