On the 2004-2009 Cadillac SRX 3.6L LY7 V6, the longitudinal 5L40-E five-speed behind the first-generation SRX 3.6L wears the bushing behind the pump seal that keeps the torque converter running true. Once the bushing wears the converter wobbles, producing a judder or shudder felt at light throttle around lockup, then destroying the pump seal and letting the front of the unit leak. Separately, gen-1 SRX owners report the transmission running hot under sustained load or in mountain driving, traced to the cooler-line thermal bypass valve restricting flow through the cooler - modifying it with the 2005-and-later cooler line is a common owner fix. Heat plus converter wobble is what kills these units. Note this is the rear-drive gen-1 unit; V8 cars use the heavier-duty 5L50 variant and the 2010+ SRX uses the transverse 6T70 instead.

This issue also affects: Chevrolet Malibu, Saturn Aura

Common Symptoms

  • Shudder or judder at light throttle around lockup speeds
  • Red fluid leak at the front of the transmission
  • Harsh or flaring shifts once hot
  • Transmission temperature climbing on grades or when towing
  • Delayed engagement when cold

How to Fix

Address the shudder early: fluid and filter with the correct spec fluid first, and if the judder persists have the front pump bushing and converter checked before the leak starts. Once the pump seal has failed the unit must come out for a pump bushing and seal, and the torque converter should be replaced rather than reused. For heat, fit the later cooler line and delete or bypass the restrictive thermal bypass valve, and consider an auxiliary cooler if the vehicle tows or lives in hills. No recall exists.

Typical repair cost:$1,500 - $4,000

On the 2004-2009 Cadillac SRX, first-generation SRX ordered with the rear self-leveling air suspension uses air-over shock units at the rear fed by a small electric compressor with an integral dryer and vent/supply solenoid head. The rubber air sleeves dry-rot and leak with age; the compressor then runs continuously trying to hold ride height, overheats, and dies. Moisture that the failed dryer no longer captures corrodes the solenoid control head, so a car can end up with leaking shocks, a burned compressor and a corroded valve block all at once. Owners report the rear sitting on the bumpstops, service-suspension messages, and a compressor that will not run at all once its fuse or relay has been taken out by the overworked motor. This is gen-1 only - the 2010+ SRX does not use rear air leveling.

Common Symptoms

  • Rear end sags or sits low, especially overnight
  • Rear will not raise when loaded
  • Compressor runs constantly or not at all
  • Service suspension system message
  • Harsh or bouncy rear ride, hissing from the rear shocks

How to Fix

Replace the rear air shocks in pairs and the compressor/dryer assembly together; replacing only the leaking shock leaves a compressor that has already been run to death, and replacing only the compressor lets the next leak kill it again. Check the compressor fuse and relay before condemning the motor. A common owner alternative is a conversion kit of conventional passive rear shocks with the compressor and level sensor disabled, which is far cheaper but permanently gives up self-leveling and load capability.

Typical repair cost:$600 - $1,600

On the 2004-2009 Cadillac SRX, the first-generation SRX roof module has a drain trough around the sliding glass with four drain hoses - two down the windshield pillars and two down the rear sail/quarter panels. Debris packs the trough and hoses, and the rear hoses split where they route down the quarter panel, so water that should exit at the wheel houses instead dumps inside the body. Owners find soaked front carpet, stained headliners, water standing in the spare tire well and rear cargo area, and secondary electrical faults where modules and connectors sit low in the car. First-generation cars are now old enough that the hoses are brittle; the same drain architecture leaks on the gen-2 body as well, but the gen-1 rear routing is the one that splits.

Common Symptoms

  • Wet front carpet or floor pan
  • Water in the spare tire well or rear cargo area
  • Stained or sagging headliner
  • Musty smell and fogging windows
  • Dripping from the A-pillar or dome light area after rain or a car wash

How to Fix

Diagnose properly before replacing seals: open the roof and pour water into the drain trough, then confirm flow out of each drain at the wheel house. Clear restricted hoses with LOW-pressure compressed air only - high pressure blows the hose off its nipple inside the headliner. Replace any split or disconnected hose section rather than just clearing it, and clean the trough of leaf debris. Dry and treat the carpet and padding, since a car that has flooded once will smell and corrode even after the leak is fixed. No recall covers this.

Typical repair cost:$150 - $900

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.

WHEELS:RIM

CERTAIN SPORT UTILITY VEHICLES AND TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 110, "TIRE SELECTION AND RIMS." THESE VEHICLES HAVE AN INCOMPLETE TIRE RIM DESIGNATION ON THE CERTIFICATION/TIRE LABEL LOCATED ON THE DRIVER'S DOOR EDGE. IN ADDITION, THE LABEL MAY ALSO BE MISSING THE TIRE LOAD RATING ON THE LABEL. ALTHOUGH THIS INFORMATION IS NOT REQUIRED BY THE STANDARD, IF A TIRE OF A LESSER LOAD RATING IS INSTALLED, THE TIRE MAY NOT BE ABLE TO SUSTAIN THE LOADS ENCOUNTERED DURING USE.
