4 recalls.

14V542000

Date: 2014-09-09. Systems: FUEL SYSTEM, GASOLINE.

Defect: General Motors LLC (GM) is recalling certain model year 2004-2007 Cadillac CTS-V vehicles manufactured October 6, 2003, to March 15, 2007, and 2006-2007 Cadillac STS-V vehicles manufactured June 23, 2005, to March 15, 2007. In the affected vehicles, the electrical terminals of the fuel pump module may overheat resulting in the melting of the flange material.

Consequence: If the flange melts, a hole may be created allowing the fuel pump to leak fuel, causing the vehicle to stall, increasing the risk of a vehicle crash. Additionally, leaking fuel in the presence of an ignition source increases the risk of a fire.

Remedy: GM will notify owners, and dealers will replace the fuel module and fuel tank jumper harness, free of charge. GM sent out interim notices in late October. The recall began on March 12, 2015. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 14405.

Do not drive: No. Park outside: No.

07V589000

Date: 2007-12-20. Systems: POWER TRAIN.

Defect: ON CERTAIN PASSENGER VEHICLES, THE REAR AXLE PINION SEAL DOES NOT MEET ALL OF THE SPECIFICATIONS AND MAY EXPERIENCE A FLUID LEAK.

Consequence: A REAR DIFFERENTIAL FAILURE MAY CAUSE LOSS OF MOTIVE POWER AND POSSIBLY LOSS OF CONTROL INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REPLACE THE PINION SEAL FREE OF CHARGE. THE RECALL BEGAN ON FEBRUARY 1, 2008. OWNERS MAY CONTACT CADILLAC AT 1-800-458-8006 OR HTTP://WWW.CADILLAC.COM; PONTIAC AT 1-800-620-7668 OR HTTP://WWW.PONTIAC.COM; AND SATURN AT 1-800-972-8876 OR HTTP://WWW.SATURN.COM.

Do not drive: No. Park outside: No.

06V020000

Date: 2006-01-25. Systems: FUEL SYSTEM, GASOLINE.

Defect: CERTAIN VEHICLES EQUIPPED WITH V6 ENGINES MAY HAVE A CONDITION WHERE FUEL IS NO LONGER SUPPLIED TO THE ENGINE. THIS CONDITION OCCURS WITHOUT THE ILLUMINATION OF THE FUEL LEVEL LOW INDICATOR LIGHT OR THE WARNING CHIME.

Consequence: IF THE ENGINE STOPS RUNNING, THE OPERATOR WILL NOT BE ABLE TO RESTART THE VEHICLE WHICH COULD INCREASE THE RISK OF A CRASH.

Remedy: DEALERS WILL REPROGRAM THE ELECTRONIC CONTROL MODULE (ECM) WITH NEW SOFTWARE FREE OF CHARGE. OWNERS WERE NOTIFIED IN DECEMBER 2005 AND ASKED TO MAINTAIN AT LEAST 1/4 OF A TANK FUEL LEVEL TO AVOID THIS CONDITION UNTIL THE PARTS ARE AVAILABLE. THE PARTS ARE NOW AVAILABLE, OWNER RENOTIFICATION BEGAN ON MARCH 23, 2006. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339.

Do not drive: No. Park outside: No.

06V007000

Date: 2006-01-13. Systems: VEHICLE SPEED CONTROL.

Defect: ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH ALL WHEEL DRIVE AND A 3.6L V6 ENGINE, THE TORQUE MONITORING FUNCTIONS OF THE ELECTRONIC THROTTLE CONTROL (ETC) ARE NOT ENABLED. THESE FUNCTIONS CAN LIMIT ENGINE SPEED AND TORQUE IF UNUSUAL ENGINE CONTROL MODULE (ECM) HARDWARE OR SOFTWARE FAILURES OCCUR.

Consequence: WITHOUT THESE FUNCTIONS ENABLED, A PERSISTENT ECM FAILURE COULD RESULT IN A THROTTLE OPENING GREATER THAN COMMANDED BY THE DRIVER AND A CRASH COULD OCCUR.

Remedy: DEALERS WILL REPROGRAM THE ECM ON THESE VEHICLES FREE OF CHARGE. THE RECALL BEGAN ON JANUARY 24, 2006. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339.

Do not drive: No. Park outside: No.

Notes on this record

  • Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
  • System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
  • Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
  • A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
