Known issues on the 2006 CTS. Six recalls are on federal record for this model year. Overheating electrical terminals in the fuel pump module can melt the mounting flange, letting fuel leak out and creating a stall or fire risk. If the ignition key moves out of the run position, the air bags may not deploy in a crash. Repeated flexing of the passenger seat's occupant-sensing mat can break its internal connections and disable the front passenger air bag. Corrosion at the front brake hose-to-caliper fitting can let the hose rupture without warning and lengthen stopping distance. A rear axle pinion seal that doesn't meet specification can leak fluid and lead to a rear differential failure, with a possible loss of motive power. And on V6-equipped cars, fuel delivery can cut out with no warning light or chime, stalling the engine with no way to restart it. Owners have filed 272 complaints for the year, and the factory diagnostic and repair procedures behind each of these systems are here.
Whether you're chasing a stall, inspecting the rear differential, or servicing the brake lines, it keeps you on the OEM procedure and the correct specification for your specific 2006 CTS.
