2010 Cadillac DTS ProblemsOil 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.
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.
The fuel pump may fail causing the engine to stall and not restart.

2010 Cadillac DTS RecallsIgnition 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.
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.
Three vehicle information labels are missing from some vehicles. These labels share tire size and pressure information, vehicle certification standards, and components used in manufacturing the vehicle. Not having these labels installed could lead to a lack of proper education and information about the vehicle, and cause abnormal tire wear and vehicle handling. General Motors has sent the three stickers to all affected vehicle owners. The owners may install the labels on their own, or they may visit a dealership for free installation. This recall began on December 22, 2009. The General Motors campaign number is 09322.
