2002 Cadillac DeVille Problems

One or more of the power window regulators (one in each door) may fail causing the window to fall into the door and not roll up.

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

The engine may develop oil leaks from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.

2002 Cadillac DeVille Recalls

Excess weight on the key ring can cause the ignition switch to move out of the run position without warning, turning off the engine. This defect can also affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. Dealers will install two 13mm key rings and key insert into the vehicle's ignition keys to correct this concern.

GM recalls certain 2002-2003 Cadillac Devillle, Seville, Oldsmobile Aurora, and Pontiac Bonneville vehicles because the fuel tank pressure sensor may fail and cause a fuel leak. In the presence of an ignition source, a fuel leak may result in a fire. Dealers will replace the fuel tank pressure sensor.

Cadillac has recalled 2000-2002 DeVille vehicles because the seat belt retractors may not lock as required when in an accident. This increases the risk of injury to vehicle occupants. Dealers will install a retainer kit to the safety belt pretensioners.

the worst purchase i made in my lifetime will never buy one again HEADACHESSSSSSSSSSSSSSS

This car is a mess with repairs and not worth the many thousands for repair work. Not to mention, most of the mechanics where I...

I bought my 02 Deville DTS for $5,800 earlier this year and it has been a complete nightmare. The alluminum engine heads and block (and alluminum head-bolts as well) are unreliable and prone to cracking, etc. The maintenance so far has cost me approx. $7/8,000.00 just to keep the car registered and running. The car itself is beautiful (Sable Black w/ factory Chrome Rims), but good looks won'...
