Category: Recall Reimbursement Problem NHTSA Complaint Description I am filing a complaint regarding General Motors’ refusal to reimburse an out-of-pocket repair related to Safety Recall N150042 on my 2009 Hummer H3 (VIN: [XXX] ). On December 31, 2025, I paid $946.06 out-of-pocket to correct the defect covered by Recall N150042 (blower motor connector module). The repair was performed at Coleman Buick GMC Cadillac in Lawrenceville, New Jersey. A complete reimbursement package was submitted to GM. GM has denied reimbursement, claiming that this recall was previously repaired in 2016. However: • No documentation has been provided to support that claim.
• No repair order number has been provided.
• No servicing dealer or repair location has been identified.
• No proof of recall closure documentation has been produced.
• No warranty claim record has been provided. Despite repeated requests, GM has refused to provide any evidence that Recall N150042 was completed in 2016. The defect was present in 2025 and was corrected by a GM-authorized dealership. If the recall had truly been completed in 2016, documentation should exist and be readily producible. GM is refusing reimbursement of $946.06 without providing supporting documentation of prior recall completion. This appears to involve either improper recall recordkeeping, improper VIN recall closure, or failure to comply with federal recall reimbursement requirements under 49 U.S.C. § 30120. I respectfully request NHTSA review of GM’s recall documentation and reimbursement practices related to Recall N150042. After submission, download or screenshot your confirmation number for your escalation packet. If you would like, I can now prepare: * A shortened version (if the online form has character limits) * A legally intensified version * Or a version framed specifically to trigger recordkeeping review rather than just reimbursement review INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Was doing a frame inspection on my hummer h3. Turns out the rear left frame rail is completely rusted through. And there are parts hanging on by a thread. I have found many complaints online about rust in this exact spot( rear left frame). I believe this issue should be dealt with immediately. Someone could be killed. The car is not that old and no other car of this age and mileage has this amount of rust penetration through the frame. GM needs to be held accountable. THIS IS A MANUFACTURING DEFECT.

The contact owns a 2009 Hummer H3. The contact stated that the vehicle failed to immediately start, and the security warning light illuminated. After several attempts, the vehicle was started. The contact stated that the failure was intermittent but had become more frequent. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was provided. The failure mileage was 97,000.

The contact owns a 2009 Hummer H3. The contact stated that while attempting to start the vehicle, the vehicle failed to start. The contact waited for a while before the vehicle started. The contact stated that the vehicle was slow to start. The contact stated that while her husband was at the store, he waited for 15 minutes before the vehicle started. There were no warning lights illuminated. The vehicle was taken to an independent mechanic who replaced the battery and starter, but the failure recurred. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was unknown.

I was having the truck inspected per state yearly requirements and when the shop lifted the truck, the bed bent backward. The frame was rusted out on both sides.

Traveling at approximately 35mph on inner city road in my 2009 Hummer H3T, both driver and passenger side curtain airbags deployed without any warning, no collision or accident, system went into crash mode and fired seat belt tensioners. Pictures taken of the exterior conditions and terrain/road conditions. Luckily just driver was in vehicle no other passengers. Vehicle taken to GMC dealer and inspected by service tech and insurance company. Multiple other Hummer H3(T) owners have experienced similar incidents. Lack of parts OEM or after market make repairs unlikely will be contacting GM.

RECENTLY MY 2009 HUMMER H3, HAS BEEN ACTING STRANGE. WHILE DRIVING DOWN THE ROAD, WARNING LIGHTS WILL FLASH, WILL BEEP, (TRACTION CONTROL, ABS, SERVICE 4WD, CHANGE OIL, SERVICE TPM), ALL THE WHILE ALL THINGS ELECTRICAL STOPS WORKING SUCH AS HEADLIGHTS, BRAKE LIGHTS, BLOWER FAN, HEATED SEAT, TURN SIGNALS, AND ALL THIS WHILE DRIVING DOWN THE ROAD AT NORMAL SPEED. IT STARTED DOING THIS AS THE WEATHER GOT COLDER BUT THIS H3 IS WELL MAINTAINED AND IS GARAGE KEPT AND I ONLY USE IT TO DRIVE TO AND FROM WORK. IT IS NOW A SAFETY HAZARD AND WITH THESE ISSUES WILL NOT BE ABLE TO TRADE IT IN. I HAVE NO IDEA WHERE TO START IN ORDER TO FIX IT. AFTER FINALLY DRIVING FOR 30 MIN OR SO SOMETIMES IT WILL FINALLY QUIT MESSING UP AND ACT NORMAL.

AIR BAG MODULE NOT RESPONDING AND IS DANGEROUS DUE TO THE FACT IT COULD DEPLOY AT A RANDOM TIME WHILE DRIVING. THE AIR BAG LIGHT STAYS ON AFTER THE VEHICLE IS IN MOTION CAUSING A POTENTIALLY DANGEROUS INCIDENT. ALSO HAIRLINE CRACKING IN THE RADIATOR DUE TO THE PLASTIC TOP OF THE RADIATOR TANK RUBBING ON THE VEHICLES FRAME.

PERIODICALLY 2-3 TIMES A YEAR FOR PAST 6 YEARS WHEN DRIVING DOWN THE HIGH CAR WILL DIE, WHEN PULL OVER TO THE SIDE OF THE ROAD, CAR WILL NOT RESTART, MAY RESTART AFTER 10 MINUTES OR AFTER TOWED TO REPAIR SHOP,TAKEN TO THE DEALER SEVERAL TIMES AND SEVERAL TIMES TO HIGH END INDEPENDENT AUTO SHOPS, NO ERROR CODE EVER FOUND. READ ON HUMMER FORUMS ISSUE WITH IGNITION SWITCH, REPLACED IGNITION SWITCH AND FAULT HAS NOT RECURRED. *TR
