I have deep concerns over ongoing issues that are being seen with the NHTSA recall campaign number 4V623000. Specifically, the loss of braking when driving over a rough or bumpy surface. The vehicle will leap forward causing me to slam on the brakes avoiding many close calls. There is a OTA update that is suppose to address this issue but I have not been able to receive these updates. As a responsible driver, I value the safety of not only myself but also those around me, and this situation and others we constantly hear about make me question the process of the recall. Every week, a number of vehicles are reported as undrivable post-OTA updates, with statistics indicating that approximately 2%-5% of owners experience this issue. With 48-hour update windows, my vehicle becomes unusable for an extended period, which is highly inconvenient and concerning. Moreover, I’ve noted that partial updates are expected, potentially extending this downtime by another 48 hours. I have had a partial update that has left my vehicle in worse shape than before, what could happen if the process is tried again? This inconsistent performance is not only frustrating, but also poses a serious inconvenience to scheduling and executing such a process. Furthermore, the fact that there are only approximately 20 service personnel available nationwide, with a mere five traveling to assist customers whose cars are rendered undrivable, is simply unacceptable. This lack of support exacerbates an already troubling situation. Given these circumstances, I urge you to address these
