The 2012 CTS-V with its LSA supercharged 6.2L is a high-performance monster that can punish itself when driven hard. Heat management issues and transmission cooling are the Achilles heels, and catastrophic engine failure from detonation is a real risk if you ignore knock or run cheap fuel.
Transmission Oil Cooler Failure (TR6060 Manual)
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: transmission fluid mixing with coolant (strawberry milkshake in overflow), transmission overheating during spirited driving, hard shifts or grinding, coolant level dropping without visible leaks
Fix: The internal transmission oil cooler in the radiator corrodes and fails, cross-contaminating fluids. Requires radiator replacement, full transmission flush, and often new clutch packs if contamination went unnoticed. 6-8 hours labor for thorough job including fluid system purge.
Estimated cost: $1,800-3,200
LSA Engine Knock / Piston Ring Land Failure
Occasional · high severity
Typical onset: 80,000-120,000 mi
Symptoms: spark knock under boost (often dismissed as normal), oil consumption increasing beyond 1 qt per 1,000 mi, loss of power, metallic rattling on cold start, catastrophic failure with rod knock
Fix: High heat and detonation crack piston ring lands, especially if tuned or run on 87 octane. Once it starts, it snowballs. Full shortblock or engine rebuild required—pistons, rings, bearings, honing, sometimes crank if it spun a bearing. Competent LS shop needs 25-35 hours, supercharger removal adds complexity.
Estimated cost: $8,000-14,000
Rear Differential Bushing Failure
Common · medium severity
Typical onset: 50,000-80,000 mi
Symptoms: clunking from rear on launch or deceleration, wheel hop during hard acceleration, vibration at highway speeds, differential visibly sagging or off-center
Fix: The OEM rubber diff bushings can't handle the torque and deteriorate quickly with spirited driving. Requires subframe drop to access. 4-5 hours labor. Most shops recommend upgraded polyurethane bushings at this point.
Estimated cost: $800-1,400
Transmission Mount Collapse (Manual)
Common · low severity
Typical onset: 40,000-70,000 mi
Symptoms: excessive driveline clunk on throttle lift, vibration in cabin at idle, hard to find gears smoothly, visible sag if you inspect under the car
Fix: The rubber transmission mount fatigues from the violent torque reversals. Simple replacement but while you're under there, check the diff bushings too. 1.5-2 hours.
Estimated cost: $250-450
Supercharger Heat-Soak / Intercooler Pump Failure
Occasional · medium severity
Symptoms: power loss after several hard pulls, intake air temps skyrocketing (120°F+), intercooler pump making noise or not circulating, heat-related timing retard
Fix: The Eaton intercooler cooling system struggles in hot climates or track use. Pump failures and clogged heat exchangers are common. Pump replacement is 2-3 hours, but system efficiency upgrades (larger heat exchanger, better coolant) prevent repeat issues.
Estimated cost: $600-1,200
CUE Infotainment System Failure
Common · low severity
Typical onset: 60,000-90,000 mi
Symptoms: touchscreen unresponsive or phantom touches, system reboots randomly, backup camera black screen, climate controls inaccessible
Fix: The capacitive touch CUE system is notoriously failure-prone. Requires CUE module replacement. 2 hours labor but parts are expensive from GM. Aftermarket options exist.
Estimated cost: $1,200-2,000
Owner tips
Run 93 octane minimum—these engines are knock-sensitive and piston failure is expensive
Change transmission fluid (manual) every 30,000 mi with Tremec-approved oil to extend TR6060 life
Install a catch can to reduce carbon buildup on the direct-injection valves
Inspect diff bushings and transmission mounts annually if you launch hard regularly
Monitor oil consumption obsessively—any sudden increase is an early warning of ring land issues
Buy one if you can afford the $10k engine-rebuild fund and want 556 HP of drama—but skip it if you need appliance reliability or can't wrench.

This defect can 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.
General Motors LLC (GM) notified the agency on July 2, 2014 that they are recalling 554,328 model year 2003-2014 Cadillac CTS vehicles manufactured August 16, 2001, to April 28, 2014, and 2004-2006 Cadillac SRX vehicles manufactured March 20, 2003, to August 11, 2006. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
Consequence: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 15, 2014. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 14172.
