Cadillac DTS Problems

Oil Leaks From Lower Engine Area

The engine may develop an oil leak 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.

Vacuum Leak From Intake Manifold

The Check Engine Light may illuminate due to an engine vacuum leak from the intake manifold area.

Engine Overheating May Cause Cylinder Head to Expand

Overheating of the engine may cause the cylinder head to expand, severely straining the head bolts and damaging the threads in the engine block. This commonly results in a blown head gasket. Our technicians tell us the engine block threads must be repaired before the cylinder head is reinstalled.

Cadillac DTS Recalls

Ignition Lock Cylinder Concern

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 2010–2011 Vehicles Due to Contact Between Starter Cable and Power Steering Line

General Motors is recalling 2010–2011 DTS and Buick Lucerne models with V8 engines due to contact between the starter/alternator cable and the power steering return line. This can result in a worn power steering return line, which can cause a power steering leak, possibly resulting in a loss of power steering. This can lead to an increase in the risk of a crash and/or an engine compartment fire. Dealers will secure or reroute the necessary lines, free of charge.

Possible Under Hood Electrical Fire

The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.

Cadillac DTS Reviews

I like this car a lot but a few things are a pain.The dash set up is not the best, the vents for the A/C only move in 2 directions not 4 so you cannot direct the cold air how you like. . Also, the clock on the dash is very shiny, and creates a lot of glare when the sun hits it, which happens a lot more than you would think. It makes it hard to see sometimes. ALso the radio is only average soun...
Fuse box under rear seat particularly the fuel pump relay gone bad dealer charges 285 for the box How is this not a recall issue when it is apparent a known problem to all dealers
the seat motor burned out, only had car 6 months. took auto to repair shop. put the new motor in, but still not working because there is a computer that controls the motor to make the seats move back and forth. Having to take car to the Cadillac dealership because they are the only ones that can repair it
