FRONT BRAKE LINE BROKE AT JUNCTION BETWEEN RUBBER PORTION OF THE LINE AND THE METAL PORTION OF THE LINE, AT A FITTING THAT WAS COVERED BY A RUBBER BOOT THAT ALLOWED WATER TO REMAIN TRAPPED, CORRODING THE FITTING. THIS OCCURRED SHORTLY AFTER STARTING UP, WHILE TRAVELLING AT 25MPH TOWARDS A RED LIGHT WITH A STOPPED CAR. THE BRAKE PEDAL FELL TO THE FLOOR RAPIDLY, AND A FURTHER PUMP OF THE BRAKE DID NOTHING TO APPRECIABLY STOP THE CAR. THERE IS A RECALL FOR THIS VERY ISSUE THAT COVERS THIS MAKE/MODEL (2007 CTS-V), BUT GM STATES THAT MY CAR WAS NOT AFFECTED. FURTHERMORE, CAR WAS AT THE DEALERSHIP THREE MONTHS PRIOR FOR BRAKE WORK.

I NOTICED THAT OCCASIONALLY MY CAR BRAKES WOULD STOP WORKING A PUSH BACK AT ME WITH A PULSING FEELING WHEN I WAS TRYING TO STOP. THIS HAPPENED TO ME 6-7 TIMES INTERMITTENTLY WHEN DRIVING VERY SLOWLY AND TURNING, IT WASN'T SOMETHING THAT I COULD RE-CREATE EACH TIME. NEXT I RECEIVED AN INTERMITTENT IN-DASH MESSAGE THAT STATED "SERVICE BRAKE ASSIST" THAT WOULD COME ON FOR A FEW SECONDS THEN DISAPPEAR. IT DIDN'T ALWAYS APPEAR WHEN THE BRAKES WERE NOT WORKING. THIS WOULD TYPICALLY HAPPEN WHEN PARKING IN A PARKING SPACE, SLOWLY MAKING A SHARP TURN. I ACTUALLY HIT CONCRETE PARKING BUFFER ONE DAY BECAUSE I COULDN'T STOP. IN TAKING MY CAR TO THE DEALER I WAS TOLD THE ELECTRONIC BRAKE CONTROL MODULE NEEDED TO BE REPLACED. AND THAT THE RIGHT FRONT WHEEL AND HUB BEARING NEEDED TO BE REPLACED DUE TO THE EBCM. THE COST WAS ABOUT $2000.00. I'VE RESEARCHED THIS ISSUES AND AM SEEING MANY CTS OWNERS WITH THE SAME ISSUE. I FEEL THIS NEEDS TO BE ADDRESSED. THE PUBLIC NEEDS TO BE NOTIFIED THAT THIS IS AN ISSUE WITH THE VEHICLE. IT IS EXTREMELY SCARY TO FIND OUT THAT YOUR BRAKES ARE NOT WORKING. I HAVE TWO SMALL CHILDREN THAT TRAVEL WITH ME OFTEN. VEHICLE OWNERS NEED TO BE AWARE OF THE BRAKE ISSUE WITH THIS VEHICLE AND CADILLAC NEEDS TO BE RESPONSIBLE IN FIXING THE PROBLEM AND NOT WAITING FOR PEOPLE TO BRING IN THEIR CARS UNTIL THEIR BRAKES ARE NOT WORKING. BRAKES ARE A MUST HAVE ON A CAR AND THIS IS A PUBLIC SAFETY ISSUE. *TR

Official recalls
6Sep 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.
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

ODI EVALUATED TWO DIFFERENT ALLEGED DEFECTS INVOLVING REAR DRIVETRAIN COMPONENTS DURING THIS PRELIMINARY EVALUATION.GM IS CONDUCTING A RECALL TO ADDRESS ONE OF THE DEFECT CONDITIONS AND ODI HAS OPENED AN ENGINEERING ANALYSIS TO CONTINUE ITS INVESTIGATION OF THE OTHER ALLEGED DEFECT. ON DECEMBER 19, 2007, GM SUBMITTED A DEFECT INFORMATION REPORT TO NHTSA CONCERNING DEFECTIVE REAR AXLE PINION SEALS IN APPROXIMATELY 275,936 MODEL YEAR (MY) 2005-07 CADILLAC CTS, STS AND SRX VEHICLES AS WELL AS MY 2006-07 PONTIAC SOLSTICE AND MY 2007 SATURN SKY VEHICLES (RECALL 07V-589).ON STS AND SRX VEHICLES WITH ALL WHEEL DRIVE, THE FRONT AXLE PINION SEAL ALSO DOES NOT MEET ALL OF GM'S SPECIFICATIONS AND MAY EXPERIENCE A FLUID LEAK.GM INDICATED THAT THE SEAL SUPPLIER MADE AN UNAUTHORIZED CHANGE TO THE PINION SEAL MATERIAL.LEAKING PINION SEALS COULD RESULT IN LOSS OF REAR DIFFERENTIAL LUBRICATION WHICH COULD RESULT IN REAR WHEEL LOCK-UP AND LOSS OF VEHICLE CONTROL. ON DECEMBER 7, 2007, ODI OPENED AN ENGINEERING ANALYSIS (EA07-017) TO INVESTIGATE COMPLAINTS OF REAR DRIVETRAIN COMPONENT FAILURE (E.G., FRACTURED REAR DIFFERENTIAL CARRIER HOUSING OR REAR AXLE HALF SHAFTS) WHILE DRIVING IN APPROXIMATELY 7,600 MY 2004 THROUGH 2006 CADILLAC CTS-V VEHICLES.THIS CONDITION MAY RESULT IN A LOSS OF MOTIVE POWER AND VEHICLE DISABLEMENT AND IS NOT ADDRESSED BY RECALL 07V-589.ODI IDENTIFIED 35 COMPLAINTS (16 TO ODI AND 19 TO GM) AND 128 WARRANTY CLAIMS POTENTIALLY RELATED TO THIS CONDITION (SEE EA07-017 OPENING RESUME).THESE COMPLAINTS ARE NOT INCLUDED IN THE FAILURE REPORT SUMMARY OF THIS CLOSING RESUME. THE COMPLAINTS AND WARRANTY FIGURES GIVEN IN THIS RESUME ARE LIMITED TO THOSE THAT (A) ARE MOST LIKELY CAUSED BY A LEAKING REAR PINION SEAL; AND (B) RESULTED IN AN ALLEGATION OF A REAR DIFFERENTIAL FAILURE WHILE DRIVING.THE DATA DO NOT INCLUDE ALL REPORTS OF SEAL LEAKAGE.
