2002 Cadillac Escalade

On January 11, 2011, ODI opened EA11-001 to investigate allegations of premature brake line corrosion failure in model year (MY) 1999 through 2003 General Motors (GM) full-size pickup trucks and sport utility vehicles sold or registered in the following region of the United States that NHTSA has viewed as salt states for investigations of corrosion related issues:Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin.The subject vehicles represent the first five MY's of GM's GMT800 platform production, of which approximately 2,038,504 vehicles were sold in salt states (the subject vehicles).The GMT800 platform includes the following vehicles:1999-2007 Chevrolet Silverado and GMC Sierra 1500, 2500 and 3500 series pick-up trucks; 2000-2006 Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon sport utility vehicles; and 2002-2006 Cadillac Escalade and Chevrolet Avalanche sport-utility vehicles.General Motors produced a total of approximately 10,427,062 GMT800 vehicles for sales in the United States, including almost 5 million that were sold in salt states.Although there are over 60 different brake pipe routing configuration used in GMT800 vehicles, with the exception of the rear crossover pipes in MY 200x-2007 vehicles that changed from rear disc to drum brakes, all of the vehicles use brake pipes from the same supplier with a common double-wall, brazed steel pipe design with a combination of hot dip Zinc-Aluminum corrosion protection coating and Aluminum paint outer layer known in the industry as AlGal (ASTM-B750). ODI analysis of field data regarding GMT800 vehicles identified a total of 3,645 complaints of brake pipe corrosion failures, including 107 alleging crashes, and 40 injuries.Though only 20% of total GMT800 production, due to age and region the subject vehicles account for a disproportionate share of the failure experience; with 2,702 of the complaints (75%), 88 of the crashes (82%) and 20 of the injuries (50%) reported in those vehicles.Analysis of the complaints showed strong correlations to vehicle age and region.For vehicles with less than 8 years of service, the complaint rates were minimal for all regions.In the salt states the failure rates begin to climb as the vehicles advance in age, particularly in the Northeast corner of the United States.The complaint rates in the salt states go from less than 0.1 incident per thousand vehicles (IPTV) at 7 years in service to over 1.0 IPTV after the 12th year of service for the subject pickup trucks and utility vehicles.Most of the failures reported to ODI occurred in vehicles with more than 10 years in service.ODI?s investigation did not identify any specific defect conditions that were causing or contributing to the brake pipe failures.Nor did the analysis isolate the problem to any subject vehicle sub-populations when analyzed by vehicle type or production range.The investigation found that vehicles experiencing brake pipe corrosion failures were likely to have general patterns of excessive corrosion on the majority of the brake pipe assembly and appear to be occurring due to expected wear out for the brake pipe coating material used in the subject vehicles and the environmental conditions in severe corrosion states.A safety-related defect has not been identified at this time.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor t

IN A LETTER DATED AUGUST 29, 2005, GM NOTIFIED ODI THAT IT WAS RECALLING CERTAIN MODEL YEAR 1999 THROUGH 2002 C/K PICKUP TRUCKS AND SPORT UTILITY VEHICLES TO CORRECT A PROBLEM WITH ANTI-LOCK BRAKE SYSTEM (ABS) WHEEL SPEED SENSOR CORROSION THAT MAY RESULT IN UNWANTED ABS ACTIVATION AND EXTENDED STOPPING DISTANCES DURING LOW-SPEED BRAKING (RECALL 05V-379).GM'S RECALL COVERS APPROXIMATELY 804,000 VEHICLES CURRENTLY REGISTERED IN THE FOLLOWING 14 SALT-BELT STATES:CONNECTICUT, ILLINOIS, INDIANA, MASSACHUSETTS, MAINE, MICHIGAN, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, AND WEST VIRGINIA.THE RECALL PROCEDURE WILL INVOLVE REMOVING THE SENSOR, CLEANING THE MOUNTING SURFACE, APPLYING A RUST INHIBITOR (ZINC-X) TO THE SURFACE, AND REINSTALLING THE SENSOR.IF NECESSARY, THE SENSOR WILL BE REPLACED. THE POPULATION AND FAILURE REPORT DATA GIVEN IN THIS RESUME ARE FOR THE FULL REGION THAT HAS BEEN CONSIDERED BY ODI AS THE SALT-BELT.THAT INCLUDES DELAWARE, IOWA, MARYLAND, MINNESOTA, MISSOURI, WISCONSIN AND THE DISTRICT OF COLUMBIA IN ADDITION TO THE 14 STATES INCLUDED IN 05V-379.THE STATES COVERED BY GM'S RECALL HAVE THE HIGHEST INCIDENT RATES FOR THE SUBJECT CONDITION, ACCOUNTING FOR 91% OF THE INCIDENTS, BUT ONLY 24% OF SUBJECT VEHICLE SALES IN THE UNITED STATES.ODI'S ANALYSIS DETERMINED THAT 840 OF THE COMPLAINTS, 244 OF THE CRASHES, AND 16 OF THE INJURIES IDENTIFIED IN THIS INVESTIGATION OCCURRED IN THOSE STATES.THE RESULTING INCIDENT AND CRASH RATES ARE 96.2 AND 28.0 PER 100,000 VEHICLES RESPECTIVELY (NOTE:RATES ARE BASED ON VEHICLE SALES, NOT REGISTERED VEHICLES). THE CORRESPONDING NUMBERS IN THE EXCLUDED PORTIONS OF THE SALT-BELT ARE 399,000 VEHICLES, 81 INCIDENTS (20.3 PER 100,000 VEHICLES), 3 CRASHES, AND NO INJURIES.THE STATISTICS IN THE REMAINING 30 STATES ARE 2,406,000 VEHICLES, 168 INCIDENTS (7.0 PER 100,000 VEHICLES), 31 CRASHES, AND ONE INJURY.GM AND ODI ARE CONTINUING TO MONITOR THE PROBLEM EXPERIENCE IN STATES THAT ARE NOT INCLUDED IN THE RECALL.GM WILL PROVIDE ODI WITH UPDATED COMPLAINT, FIELD REPORT, AND WARRANTY DATA IN NOVEMBER 2005.ODI AND GM WILL REVIEW THAT DATA AND ASSESS THE APPROPRIATENESS OF THE CURRENT SCOPE OF THE RECALL AT THAT TIME.

THIS INVESTIGATION INVOLVES THE GENERAL MOTORS CORPORATION (GM)THROTTLE BODY (TB) UTILIZED IN MODEL YEAR (MY) 1999-2002 SILVERADO, SIERRA, TAHOE, SUBURBAN, AVALANCHE AND YUKON (SUBJECT VEHICLE(S)) WITH 4.8L, 5.3L, AND 6.0L ENGINES. THE TB VALVE MAY INTERMITTENTLY STICK IN A CLOSED POSITION.IN SUCH A SITUATION, AN OPERATOR MAY APPLY ADDITIONAL ACCELERATOR PEDAL FORCE TO INCREASE ENGINE SPEED.THE APPLICATION OF ADDITIONAL ACCELERATOR PEDAL FORCE, TO OPEN A STUCK THROTTLE VALVE, MAY OPEN THE THROTTLE VALVE MORE THAN INTENDED AND, IN TURN, ACCELERATE THE ENGINE AND VEHICLE MORE THAN INTENDED AND REASONABLY EXPECTED BY THE DRIVER.ON AUGUST 1, 2002, THE OFFICE OF DEFECTS INVESTIGATION (ODI), OF THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA), OPENED THIS ENGINEERING ANALYSIS.THE INVESTIGATION REVEALED THAT TWO FACTORS MAY CAUSE THE DEFECT: 1) TB MANUFACTURING PROCESS PROBLEMS; AND 2) ACCUMULATION OF DEPOSITS (A PCV SYSTEM BY-PRODUCT) ON OR AROUND THE TB THROTTLE VALVE AND BORE.ODI CONCLUDES THAT THE TB PERFORMS IN A DEFECTIVE MANNER AFTER ANALYZING GM?S DATA SUBMISSIONS, AND TEST DATA COLLECTED BY THE VEHICLE RESEARCH AND TEST CENTER (VRTC).FIFTY-NINE CRASHES ARE ALLEGED TO HAVE OCCURRED AS A RESULT OF GM?S TB DEFECT.THE MAJORITY OF THE CRASHES INVOLVE A SINGLE VEHICLE, ENGAGING IN A CLOSE QUARTER VEHICLE MANEUVER (OR LOW SPEED), AND CAUSING ONLY MINOR PROPERTY DAMAGE.FOUR OUT OF THE FIFTY-NINE CRASHES INVOLVE INJURY, AND THOSE INJURIES WERE MINOR.ALTHOUGH GM?S TB IS DEFECTIVE, BASED ON THE EVIDENCE GATHERED, ODI HAS FOUND THAT THE ACCELERATOR PEDAL FORCE REQUIRED TO OPEN A STUCK THROTTLE VALVE IS NEGLIGIBLE, AND THE THROTTLE VALVE DOES NOT STICK IN THE OPEN POSITION.THEREFORE THIS ENGINEERING ANALYSIS (EA02-015) WILL BE CLOSED AT THIS TIME.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.FOR A DETAILED DISCUSSION OF THE TB COMPONENT AND TESTING, PLEASE SEE THE ATTACHED REPORT.

Purchased this vehicle from a friend who was inherited from his father’s estate. He hadn’t driven the vehicle for sometime. When meeting up at the DMV to transfer ownership he noticed that the brakes were spongy. And purchased some brake fluid in case the fluid was low. Neither my friend or myself are mechanically impaired so We made the exchange of ownership and went on our way home. When we arrived my step father felt the need to investigate the issue. He discovered that every brake line under the drivers seat back approximately 24” were so rusted and soaked with brake fluid that fluid was dripping and making a puddle and was unable to pinpoint where the hole was at that time. We decided that the vehicle was too dangerous to drive, and returned to [XXX] to retrieve his trailer to bring the Escalade to his shop for safety reasons. We tried researching and did find where GM’s SUV’s did have a recall on this matter. The Cadillac is in excellent condition inside and out. The leather seats other than the drivers show no wear at all. Carpets show no wear. The exterior is in excellent shape without chips or dings. Basically a like new with 104,000. Miles which is considered low miles for its age. For our assessment of this issue that no matter the age of the vehicle, the Manufacturer should in fact take responsibility, and there for replace the brake lines, and the necessary bleeding of the system. In a timely manner as so I am able to drive it in a safe condition. Thank you Sincerely [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The problem is in the anti-lock braking system. When the vehicle slows to under 15 mph. and you apply the brakes the brake pedal" kick back" occurs with loss of braking . Making the vehicle a hazard to drive. Now with repeated depression of the brake pedal the vehicle does stop. But, if you are approaching a stopped car or some other stationary object a collision could occur. Thankfully this has not happened to me or my wife, as we are aware of this condition and prepare for it while stopping the car. The reason why this happens is because GM no longer produces the part that would alleviate this condition. The part is known as a Brake Pressure Warning Switch, part # 88983914. It is part of the ABS system. I have spent countless hours on the internet trying to obtain this part, but to no avail. When you look up the part web sights will show you a picture of the part, but when you click on it you always get the same message, "part not available." I believe that this is a safety issue that GM could alleviate by producing it again. Last week I had my Escalade in for an oil change at Anschuetz Chevrolet, (where I bought this vehicle), while there I spoke with the service manager who told me "this is not an isolated problem." We can't get some parts for vehicles that are only 10 years old. This is terrible that a corporation manufactures a product then does not continue to make replacement parts for that product making it obsolete. Or in my case causing an issue with SAFETY! Please, would you look into this growing problem to help make my vehicle whole and safe. In essence what GM is doing is telling all of us: "Well if you can't get the part you want to fix your car simply buy a new one. I await your answer, please help.

Driving carefully out of [XXX] here in Walker Minnesota using the newly opened east side of the parking lot exit and 50 feet later as I accelerated the Heavy Full size spare tire fell from under the rear of the truck and my 2002 Cadillac EXT left the ground as the tire bounced back up against the truck!!! If we had been going faster and in a Different area we may have been Killed! It's a terrible design to store a full size and very heavy spare tire.
