I am submitting a claim pertaining to NHTSA Recall Number 25V636000 which pertains to a engine starter issue that can result in fire. This recall was reported first on September 23, 2025 and has been gone without a remedy. Since as of today, it has been 212 days without a solution that I am driving a car that may catch fire. This is too long and I am seeking remediation in the form of a replacement vehicle.
