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…
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.

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.

Needed recall for hummer H3. "Reduced power/service stab system/traction" notification that appears without warning, and immediately drops the engine to almost no ability to accelerate. This began happening in local traffic, then on the interstate at high rates of speed. Gm has been notified of this issue, even after numerous attempts to repair this very dangerous malfunction without success, they are unwilling to address it with a recall. The most dangerous of the numerous times this happened was on 4/27/17. I had just left moses gm of charleston, wv after they had repaired the vehicle for this issue. I drove approximately 5 miles on interstate 64 before losing power, and almost being struck by a vehicle on the south charleston bridge. The dealership towed me back to the service center where the vehicle was once again unsuccessfully repaired. It seems that this IS an issue with gm vehicles around the same time period, and not just the hummer line. Any help would be greatly appreciated.
