IN AUGUST 2011, VEHICLE WAS TAKEN TO DEALER IN RESPONSE TO RECALL 10355 WITH APPROXIMATELY 31,600 MILES. PART 19124390 PASSENGER SIDE SEAT CUSHION/AIRBAG MODULE WAS REPLACED. IN FEBRUARY 2019, SERVICE AIRBAG LIGHT BECAME ILLUMINATED AND TAKEN TO DEALERSHIP FOR DIAGNOSIS. MILEAGE WAS APPROXIMATELY 66,000. THE DIAGNOSIS WAS TO REPLACE THE PASSENGER SIDE SEAT CUSHION/ AIR BAG MODULE, WHICH IS THE SAME ITEM REPLACED IN AUGUST 2011. EVEN THOUGH IT HAS BEEN 7/8 YEARS SINCE REPAIR, THE VEHICLE HAS BEEN DRIVEN LESS THAN 35,000. OF THOSE 35,0000, A FRONT PASSENGER WAS PROBABLY IN THE PASSENGER SEAT FOR ONLY 15,000 MILES. I BELIEVE THIS SECOND SENSOR PART IS DEFECTIVE AND SHOULD BE REPLACED AT CADILLAC'S EXPENSE. DOCUMENTATION INCLUDING INVOICES AND ESTIMATES AVAILABLE UPON REQUEST.

TAKATA RECALL. WE HEARD FROM GM RECALL CENTER THAT OUR LOCAL GM DEALER, RALLY AUTO, DID THIS RECALL NOV 15, 2013. THE AIRBAG LIGHT IS ON AGAIN NOT EVEN 5 YEARS LATER. WE ARE SENIORS AND DO NOT DRIVE THIS CAR THAT FAR. WE TOOK IT IN TO RALLY AND THEY PUT IT ON A MACHINE AND CHARGED US $143 TO TELL US IT WOULD BE ALMOST $1000 TO FIX THE AIRBAG MODULE IN THE PASSENGER SEAT. IN RESEARCHING, IT SAYS THAT THE RECALLS NEVER EXPIRE IF THE MANUFACTURER AND PARTS AVAILABILITY ARE STILL THERE. WE ARE SENIORS ON LIMITED INCOME AND THIS IS EXHORBITANT FEES. THEY DID NOT CHECK UNDER THE SEAT TO SEE IF IT MIGHT BE A SIMPLE BREAKAGE OR BENDING OF WIRES I DON'T BELIEVE. CAN YOU HELP US GET THIS FIXED? IT SEEMS IT SHOULD NOT BE MESSED UP SO SOON. THANK YOU.
THE CAR IS RUNNING LIKE IT IS STUCK IN SOME KIND OF SAFETY MODE. IT DOES NOT WANT TO ACCELERATE UNLESS IT STARTS ACCELERATING IN THIRD GEAR. IT DOES NOT COME OUT OF 3RD GEAR AT ALL.

THE CAR IS RUNNING LIKE IT IS STUCK IN SOME KIND OF SAFETY MODE. IT DOES NOT WANT TO ACCELERATE UNLESS IT STARTS ACCELERATING IN THIRD GEAR. IT DOES NOT COME OUT OF 3RD GEAR AT ALL. THE ENGINE LIGHT AND AIRBAG LIGHTS ARE LIT UP ON THE DASH. THERE IS A COUPLE OF RECALLS LISTED FOR THE SAME EXACT YEAR MAKE AND MODEL BUT IT SAYS THAT THIS VIN NUMBER IS NOT UNDER RECALL. I THINK THAT THIS VEHICLE NEEDS TO BE INSPECTED TO SEE IF IT ACTUALLY DOES NEED TO BE LISTED UNDER THOSE RECALLS. IT IS NOT JUST THIS ONE SPECIFIC VIN NUMBER HAVING THESE ISSUES EITHER. I HAVE TALKED TO QUITE A FEW CADILLAC OWNERS THAT ARE HAVING THE SAME PROBLEMS AND THEIR VEHICLES ARE NOT LISTED UNDER THOSE RECALLS EITHER. IF YOU TURN ON THE CAR YOU PUT IT INTO DRIVE THE CAR REMAINS STUCK IN 3RD GEAR AND WILL NOT SHIFT THROUGH THE GEARS PROPERLY.
TAKATA RECALL. WE HAVE AN AIR BAG LIGHT ON THE PASSENGER SIDE. TOOK IN TO DEALER. SAYS THE CODE B092 NEEDS PASS. PRESENCE. QUOTED US ALMOST $1000 FOR REPAIR. NOTE THAT THIS RECALL WAS TAKEN IN AND DONE NOV 2013. WHY IS IT MESSING UP AGAIN? HOW LONG IS THE REPAIR SUPPOSED TO LAST? SHOULDN'T IT BE FIXED AT NO COST TO US?

THE CHECK ENGINE LITE NEVER WENT ON SO I STOP DRIVING IT TILL IT WENT TO THE DEALERSHIP BECAUSE I WAS GOING TO HAVE IT TOWED AND WHEN I STARTED UP THE CAR THE ENGINE BLEW. I BOUGHT THIS CAR WITH A LIFETIME LIMITED POWERTRAIN WARRANTY AND IT COVERS THE ENGINE. THE WARRANTY IS GOOD FOR LIFE AS LONG AS I OWN THE CAR AND KEEP UP ON ALL MAINTANCE AT A GM DEALERSHIP WHICH I DID FOR 8 YRS. THE WARRANTY COMPANY WILL NOT COVER THE COST OF THE REPAIR BECAUSE THE DEALERSHIP THAT I BOUGHT IT FROM CLOSED. I CALLED GM AND THEY WILL NOT DO ANYTHING BECAUSE THEY STATED I NEED TO GO TO THE WARRANTY COMPANY. NOTHING STATES IN MY WARRANTY IF THE DEALERSHIP CLOSES THAT MY WARRANTY IS INVALUED. THAT IS NOT RIGHT I FEEL THAT GM SHOULD PAY THE COST OF THIS ENGINE BECAUSE I BELIEVE MY CHECK ENGINE LITE WAS FAULTY.

Official recalls
614V542000 · 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.
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.

2EQ11001 · 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
