Dear NHTSA, I am filing a formal complaint regarding Tesla’s refusal to properly address a critical safety recall on my vehicle (Recall Number 24V554). This recall involves a significant safety issue that Tesla is legally obligated to remedy free of charge under the National Traffic and Motor Vehicle Safety Act. The required over-the-air software update associated with this recall repeatedly fails to install, getting stuck at 50% completion. I scheduled a service appointment and took the vehicle to Tesla for assistance. However, Tesla informed me that they will not diagnose the issue or investigate why their software update fails to install unless I agree to pay $255.00 for a general diagnosis. Additionally, they require me to pre-approve a total of $2,658.28, including the diagnostic fee, in case the computer needs to be replaced. This approach leaves me unable to proceed with a mandatory safety recall and directly contradicts Teslas legal obligation to repair safety-related defects at no cost to the consumer. I urge the NHTSA to investigate Tesla’s practices concerning this recall and their apparent refusal to adhere to their obligations under the law. This situation raises concerns about Teslas commitment to addressing safety-critical issues in a manner that ensures public safety and compliance with federal regulations. Thank you for your attention to this matter.
