During normal driving, my service stibilatrak light comes on. While the message is on, the TCS kicks in and it grabs the wheel and stops the car. I've been reared ended once and two barely missed collisions. When the TCS activates, it stops the car completely and the only way to drive the car is to turn it off for a few second and then restart it. That resets the computer and turn the message light off. The TCS or ABS does not come on in the dash, just the stilibatrak message in the message center. Once it's turned off, it does not come on until the next time the TCS activates. I've had several diagnostic tests to check the problem or get a code but there is no code. I've been told that the car is clear of codes. The dealer cannot find a code or the problem. I've spent several hundred dollars on trying to locate the problem. The car, as is, is a death trap. I can't drive it because I don't know when the traction will kick on. I've taken good care of my car, nice bodywork and low milage but it's not safe to drive and no one knows how to fix it, including the dealer. At $200 an hour to try to find the problem is unforeseeable financially on my pension. One option is to junk the car for $200. I can't donate or sale it because it will not pass MD inspection. I can't trade it; I can't afford another car note. I've had this issue for almost a year. This happens every time I drive it, so I had to buy another car which I was not ready to buy. No major damage to report.

Transmission cooler line fittings have dissimilar metals causing the threads inside the radiator transcooler to strip and dump coolant into Transmission lines and on road along with what was the transmission fluid as well as steam rolling out blocking vision through my windshield going uphill on a dangerously busy road crossing.This is a well known manufacturing defect that has yet to be handled. This could have gotten me and my 3 year old son seriously hurt by sudden loss of power and slick roadways not being able to avoid or brake properly or even steer away from on coming collision. The dissimilar metals are aluminum nut with a mild steel washer backed by a stainless steel washer before it contacts the radiator. This car has 101k miles and has been babied it's entire life. And when I see the 4 brake lines are about to rust out after all the repairs that have already been done. This is just poor quality material and craftsmanship. Easily could have been avoided by simply using a different metal than mild steel between dissimilar metals.

14V542000 · Fuel System, Gasoline:delivery:fuel Pump

Sep 9, 2014

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 & remedy

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.

14V394000 · Electrical System:ignition

Jul 2, 2014

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 & remedy

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.

EQ11001 · Iee Passenger Sensing System Mats

Opened Feb 7, 2011 · Closed Jul 19, 2011

Status: closed (inferred from source dates) · Air Bags:frontal:sensor/control MODULE-INACTIVE

On December 17, 2010, General Motors (GM) notified the NHTSA that it had decided certain 2005 - 2007 model year Cadillac CTS vehicles contain a safety related defect.GM stated that certain CTS vehicles contain a passenger sensing system mat, manufactured by IEE, in the front passenger seat that may flex causing the mat to kink, bend or fold.If this flexing causes the connections in the mat to break, the passenger airbag could become disabled.Non-deployment of the front passenger air bag in the event of a crash necessitating that air bag's deployment may reduce protection of the passenger and increase the risk or severity of injury to them.This issue was assigned recall number 10V-644.On February 8, 2011, RMD mailed an information request (IR) letter to IEE requesting a list of purchasers for any company that was sold the same or similar defective mats.RMD also requested IEE supply the year, make and models of compatible vehicles for each of the mats it listed in its response.IEE responded on February 15, 2011, reporting that the mats recalled in GM recall 10V-644 were developed specifically for the 2005-2007 Cadillac CTS.IEE noted that, ...the CTS Sensor Mat is not the same or similar to any other sensor mat manufactured by IEE.IEE further explained that the sensor mats were sold to Lear Corp. (Lear), for incorporation into seat assemblies, with the seat assemblies finally being sold to GM.Also, some sensor mats were sold to Integrated Manufacturing and Assembly, LLC (IMA) who would then re-sell the mats to GM to use as service parts.Ultimately, these parts were all sold to GM for use in the 2005-2007 Cadillac CTS vehicles.According to its 10V-644 Defect Report, GM reported that some vehicles outside the recall population have ...significantly lower incident rates and will be provided a special coverage.This special coverage includes a free repair should the same issue occur to non-recalled 2005-2007 Cadillac CTS vehicles up to 10 years or 120,000 miles.On April 7, 2011, RMD mailed an IR letter to GM to gather more information on GM's decision to only recall a portion of the vehicles that contained the subject IEE mats.RMD also requested that GM provide updated to current warranty claims, field reports, and other field information for CTS vehicles both recalled and those under the special coverage.On May 19, 2011, GM responded with a letter and several CD attachments that were submitted to NHTSA's Office of the Chief Counsel along with a request for confidentiality.GM confirmed that the IEE mats recalled in 10V-644 were only used in the 2005-2007 Cadillac CTS.GM also explained its reasoning in only recalling a portion of the CTS vehicles containing IEE mats.Due to various production phases, error detections, and false corrections, certain vehicles were more prone to mat failures than other vehicles.GM identified 4 distinct seat assembly production periods and chose to recall CTS vehicles depending on which seat assembly each vehicle received.Examining the data submitted in regards to warranty claims, field reports, and incidents, the CTS vehicles that were included in the safety recall were responsible for about 80% of the overall claims.CTS vehicles included in the special coverage (essentially an extended warranty), those with seat assemblies from other identified production phases, were responsible for about 20% of the overall claims.As GM has provided clear data to support its recall decision and since no other manufacturer has installed these same or similar passenger sensing system mats / seat assemblies in their vehicles, this Equipment Query is satisfied.This EQ is cl

IN JULY OF 2007 THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED PE07-037 TO INVESTIGATE ALLEGATIONS THAT THE REAR DIFFERENTIAL MAY FAIL CAUSING A LOSS OF MOTIVE POWER, AND IN SOME INSTANCES A LOSS OF CONTROL, IN MODEL YEAR (MY) 2004 THROUGH 2006 CADILLAC CTS, CTS-V, AND STS VEHICLES.AS A RESULT OF THAT INVESTIGATION GM ISSUED RECALL 07V-589 TO CORRECT A LEAKING PINION SEAL PROBLEM.EA07-017 WAS OPENED TO INVESTIGATE COMPLAINTS OF FRACTURED REAR DIFFERENTIAL HOUSINGS OR REAR HALF SHAFTS IN HIGH PERFORMANCE CADILLAC CTS-V VEHICLES.ACCORDING TO GM, THESE FAILURES RESULTED FROM THE CUMULATIVE DAMAGE FROM MULTIPLE POWER HOP EVENTS THAT CAN OCCUR DURING VERY AGGRESSIVE DRIVING. IN FEBRUARY 2008 INVESTIGATORS FROM ODI MET WITH GM REPRESENTATIVES TO CONDUCT TESTING OF THE SUBJECT CTS-V VEHICLES.DURING THE TESTING THE SUBJECT VEHICLES WERE SUBJECTED TO CONSIDERABLE TORSIONAL FORCES FROM STANDING STARTS AND WHILE DRIVING.POWER HOP OCCURRED DURING SOME OF THE MOST AGGRESSIVE DRIVING MANEUVERS.THE TESTING DID NOT RESULT IN FAILURE OF ANY REAR DRIVETRAIN COMPONENTS.THE ENGINEERING DESIGN AND TESTING DATA SUPPLIED TO ODI BY GM AND THE RESULTS OF THE TESTING CONDUCTED BY ODI TEND TO SUPPORT GM'S POSITION THAT THE DIFFERENTIAL DESIGN IS NOT DEFECTIVE. COMPLAINTS LISTED IN THE FAILURE REPORT DO NOT INCLUDE THOSE INDICATIVE OF FAILURE OF THE REAR PINION SEAL IN CTS-V VEHICLES COVERED BY RECALL 07V-589. FURTHER INVESTIGATION IN THIS MATTER WOULD NOT BE AN EFFICIENT ALLOCATION OF AGENCY RESOURCES.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.SEE ATTACHED CLOSING REPORT FOR FURTHER DETAILS.
