Theses templates dosent recognize the key and kicks on the security system which stops the motor from turning on. So you are stuck for 10 minutes then you can try again all so sometimes the motor tries to turn on by just sticking the key in the ignition before you even turn it. By looking at youtube alot of the H3s and the Colorados do this

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: [[redacted]] ).

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)
