Cadillac DeVille engine cuts off when attempting to park, suspected not related to battery on Cadillac DeVille

Some Cadillac DeVille owners report experiencing engine shutdowns while attempting to park, which may not be related to the battery. These issues could stem from various causes, including problems with the fuel system, air intake system, or ignition system. A malfunctioning MAF sensor has been noted to trigger the check engine light and lead to engine stalling. Additionally, a defective ignition switch or crankshaft position sensor may also contribute to unexpected engine shutdowns. In some cases, more recent models feature an automatic engine shut-off at stop lights, which is normal but requires the driver to deactivate the feature each time the vehicle is started. Owners are advised to have their vehicles inspected by a qualified mechanic to diagnose and resolve the specific issue causing the engine to cut off.
