2008 Chevrolet Tahoe

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

The statistical data regarding problem experience in the table above are net counts for unique vehicles.Review of information in this PE discloses that while accounting for approximately two-thirds of the total population, MY 2007 subject vehicles are cited in more than 90 percent of the consumer complaints, injury reports, and warranty claims, respectively.In addition, improvements in the door handle manufacturing process during the MY 2007 production resulted in a decline in the occurrence of peeling/flaking of the thin chrome plating.Other environmental factors were also identified that may have influenced the occurrence of the condition which poses the alleged safety risk.Additional analysis is required to identify the specific vehicles most susceptible to peeling or separation of the chrome plating from the handle, and to assess the significance of its occurrence.This PE has been upgraded to an Engineering Analysis to facilitate further study.

GM'S RECALL RESOLVES THE SAFETY DEFECT CONCERNS PURSUED BY THIS INVESTIGATION.THIS ENGINEERING ANALYSIS IS CLOSED.

IN RESPONSE TO AN INFORMATION REQUEST LETTER SENT BY THE OFFICE OF DEFECTS INVESTIGATION(ODI) DURING PRELIMINARY EVALUATION PE08-010, GM PROVIDED ODI WITH 41 ALLEGATIONS OF NON-CRASH ENGINE COMPARTMENT FIRES INCLUDING 16 ALLEGATIONS OF FIRES ORIGINATING WITH THE IGNITION IN THE OFF POSITION.ONE OF THE FIRES WAS DETERMINED TO BE CAUSED BY AN ARSON EVENT.ODI HAS ALSO RECEIVED 5 REPORTS, 4 OF WHICH ARE OF DUPLICATIVE OF REPORTS PROVIDED BY GM, ALLEGING NON-CRASH ENGINE COMPARTMENT FIRES IN THE SUBJECT VEHICLES.IN TOTAL, ODI IS AWARE OF 41 NON-CRASHENGINE COMPARTMENT FIRES IN THE SUBJECT VEHICLES THAT ARE UNRELATED TO ARSON.EIGHT OF THE 41 FIRE ALLEGATIONS ALSO ALLEGE PROPERTY DAMAGE AS A RESULT OF THE FIRES.THIS PRELIMINARY EVALUATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS (EA08-010) TO FURTHER ASSESS THE SCOPE, FREQUENCY, ORIGIN AND CAUSE OF THE ALLEGED NON-CRASH RELATED ENGINE COMPARTMENT FIRES IN THE SUBJECT VEHICLES.

The battery energy control module GM Part # 84442220 located inside the HV battery assembly caught fire. The harness that was most affected was the battery cell voltage sense wires. The way the battery voltage sense circuit is manufactured seems dangerous as there is no fusible link between the battery cell and the module. If a short circuit occurs the full current of the cell will be induced on a very thin gauge wire going to the module which will result in a fire.

The contact owned a 2008 Chevrolet Tahoe. The contact stated that while stopped by the school to pick up one of his children, the vehicle was parked. The contact then noticed smoke emanating from the driver's front seat. The contact safely removed his occupant, who was his autistic child, seated in the front passenger seat. The vehicle was engulfed in flames.  The fire department was called, and the fire was extinguished. The contact and his children did not sustain any injuries. The vehicle was towed to a local towing yard. The insurance company was notified and towed the vehicle to a facility used by the insurance company. The insurance company declared the vehicle a total loss. The contact believes the fire to be related to an electrical failure due to the hood of the vehicle not being damaged. The manufacturer was not made aware of the failure. The failure mileage was approximately 134,000.

Was Delivered. Took for a test drive. Stalled at stop sign. Restarted went down the road stalled and slammed into park. Contacted company was told to take to local GMC/Chevy, (said they did a bunch of research and this part should work) basically guessing had my vehicle for 9 months replaced some sensor. Had my boyfriend Drove to red light, not even half a block, stall (stable track sensor) but lost all electric but v8 still ran took to another ( had towed) to another local shop they had for 4+ months couldn't figure out said it was running 18+ codes and would cost too much to go through. Contacted company the gentleman politely laughed and said ur kidding me right it's been years I tried to explain how long it was taking due to both repairs company had it over a year n half. No sympathy he knew exactly what he sold.

I had bought the 08 Tahoe hybrid. The day it was delivered, it stalled I called the dealership out of Minnesota and was told oh it could be this it could be that went to two local shops and a private shop all had different specifications as to what was wrong with the car due to so many codes being thrown out. You would try to take off from a stop sign or a red light car would completely lose all power, almost had multiple people slam into me because it always happened, caused so much anxiety because my only wheels to get my children around. Once again was told to take it in GM had it for over a year and could not figure the issue out. I was told by the dealer multiple times it was not their issue and they knew the position I was in an said it was inspected but refused to send me the paperwork.

Cooper Discoverer All-Terrain LT265/70R17 123S All-Terrain Tire. Just purchased from Walmart Oct 31, 2024. This is the email I sent to Walmart Claims Service, Inc. First of all, the tires were installed in the wrong manner. The Tire Pressure Sensor Monitor (TPMS) was installed on all four tires. I was fraudulently told that the car battery was bad and that the TPMS were unable to be reset. My auto battery was only purchased 3 months ago and the best battery that can be purchased from NAPA for my vehicle. When I returned to the indicated store, I was given the same BS story about my car battery being bad without proof of defect. This was an obvious attempt to get me to purchase a replacement battery. Fortunately, I have my own device to reprogram the TPMS devises. I was able to reprogram the TPMS devices on all 4 tires without problem on the first try. This is clear evidence of bad faith dealing on the part of Walmart. The tire pressure is 80psi. at the maximum load rating of the tire. At the recommended pressure of 44psi the tires are too soft. The tire squishes and rolls when driving around moderate curves at the posted speed limit of the roadway. This causes an unsafe condition and very dangerous to trailer a pull along vehicle. These tires are UNSAFE!!!! And that is a fact that cannot be disproven. Walmart is totally responsible for any product liability as a result of any death or damage sustained. I am not interested in entertaining any comments about, "if you feel they are unsafe, then don't drive the vehicle". I didn't purchase new tires for my vehicle to sit in the driveway. These tires need to be replaced ASAP with an alternate viable option. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ At the recommended operating tire pressure of 44psi the sidewalls are not supportive enough to prevent the rear end from pulling to the side, slipping, and sliding. This is more prominent when going around moderate curves.
