2001 Chevrolet Tahoe

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

ODI'S REVIEW OF COMPLAINT DATA RECEIVED SINCE THE CLOSE OF EA04-011 REVEALED NO INDICATION THAT THE INVESTIGATION SHOULD BE RE-OPENED.MORE DETAILS CAN BE FOUND IN THE FEDERAL REGISTER NOTICE ENCLOSED IN THE DP05-009 PUBLIC FILE.ODI RESERVES THE RIGHT TO REOPEN THE INVESTIGATION IN THE FUTURE SHOULD CONDITIONS WARRANT.

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.

THERE HAVE BEEN LESS THAN 2 COMPLAINTS PER 100,000 SUBJECT VEHICLES RELATED TO THE ALLEGED DEFECT.THE OLDEST VEHICLES (MY 1999) HAVE ONLY 2 COMPLAINTS IN OVER 140 THOUSAND VEHICLES AFTER OVER 4 YEARS IN SERVICE.THE RATE OF WARRANTY CLAIMS POTENTIALLY RELATED TO THE ALLEGED DEFECT IS LESS THAN 0.1%.THERE ARE NO KNOWN INCIDENTS INVOLVING RAPID LOSS OF TIRE PRESSURE OR LOSS OF VEHICLE CONTROL. A DEFECT TREND 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 NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY WILL TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.

Passenger side rear air conditioning blower motor caught on fire and burned vehicle out completely. Fire trucks called to put out fire but is completely burned out. My safety was at risk flames in back by the time I got stopped on highway. Thankful no one was riding in back seat. First issue I had with it and it torched the vehicle. No warnings on dash. Vehicle is waiting to be inspected by insurance adjuster.

The contact owns a 2001 Chevrolet Tahoe. The contact stated that while driving 35 MPH, the brake pedal was depressed, and the vehicle pulled to the left very hard, almost causing the contact to lose control of the vehicle. The ABS and brake warning lights were illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the EBCM motor relay circuit needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 91,632.

I bought Achilles desert hawk uhp 285/50/R20 tires in late 2019 from Walmart . and had them mounted in 2020 from discount tire. Within 10 months of tires being mounted I had a vibration and it was getting worse every day so I started looking at it and found I had a separated tire on the driver's side front. I put my spare on and contacted Walmart which told me sorry for your luck and there is nothing they can or will do.so I contacted discount and they said to contact Achilles tire. I did and never heard back from them. I then forgot about it until roughly 5 months ago when passenger tire was separated. Then 3 days ago the passanger rear separated and now today the driver's rear has separated. I understand 1 tire possibly 2, but to have all 4 tires separate in less than 2 years and in under 10,000 miles is mind blowing to me..I have all the tires and I filed a complaint with Walmart and Achilles after the 2nd one. I honestly don't think it's discount tires responsibly. I only had them install tires because walmart would make excuse after excuse and I got fed up with it. There should be some sort of liability to the manufacturer and to Walmart. I am asking you if it's possible to look into this. 4 tires separate in 2 years you ée⁷⁷e77⁷e⁷

In the past I have sent several emails to Chevrolet corporate office re the ABS brake system on my Tahoe which first failed with only 130 miles on the vehicle. Vehicle almost tipped over but I recovered the braking system and stopped vehicle only inches from going off a cliff and into the ravine below. I love my Tahoe which now has 109000+ miles on it but the ABS brake system has never worked and on several occasions almost wiped out myself and a passenger because brakes failed to engage. I filed several complaints with the Chevrolet dealer in Austin, TX where I bought my Tahoe and also here in Taos, NM where I currently live. Recently I had the Chevrolet dealer here in Taos run a diagnostic on my ABS brakes. Result was that the brake system was defective and would cost $2000 to repair! I feel Chevrolet should pay for the repair since my Tahoe was delivered from the factory with defective ABS brakes. As it is, my Tahoe cannot be resold since the system as is could kill anyone in this vehicle if they did not know how to recover when pedal is all the way to the floor and vehicle is picking up speed rather than slowing down. Certainly even I could hit an elk standing in middle of highway because I would not be able to recover brake system in time.

THE FRONT PASSENGER SEAT BELT LOCKS UP AND CAN'T BE ADJUSTED. IT CONTINUES TO GET TIGHTER AFTER FASTENING AND ALLOWS FOR NO MOVEMENT. IT IS VERY UNCOMFORTABLE AND DOES NOT ALLOW FOR ANY MOVEMENT. IT HAS BEEN THAT WAY SINCE ORIGINAL PURCHASE IN 2001. I HAVE BROUGHT TO ATTENTION OF CHEVY DEALERSHIP. ANSWER ALWAYS BEING THAT THERE IS NO RECALL FOR THIS ISSUE.

Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.
