- What component or system failed or malfunctioned, and is it available for inspection upon request? NHTSA Recall ID: 23V445, Fuel Pump Delivery Module How was your safety or the safety of others put at risk? Vehicle at risk to lose drive power, increasing the chance of crashing while operating. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Mercedes dealership states they will not repair recalls on the weekends only M-F. I work at the hospital M-F 0800-1700. The dealership will not make any accommodations in assisting me with my schedule to get car fixed. They refuse to let me make apt on Sat/Sundays and they will not have car towed to and from Mercedes dealership to my work. They have suggested for me to leave work around 1400 to drop car off and pick up a loaner for repairs M-F. This is not feasible.

Upon starting my vehicle today the center screen did not power on. The vehicle displayed several messages indicating various safety features were unavailable, including blind spot assist, lane keeping assist, parking assist, etc. Additionally, the exterior cameras (e.g., reverse camera) were inoperable as well. Since the center screen controls the sound system and climate control system, those systems were also unavailable. I restarted the car several times but the screen remained off. I purchased this car in August 2022 and have driven it approx. 3,600 miles - this is the second time this issue has occurred. The first time happened in Sept 2022 and it resolved by itself the following day. However, I believe this problem presents a safety concern since most, if not all, of the vehicle's various safety systems are disabled when it occurs.
