There was an SRS Error message. The SRS system is non-functional on a vehicle with 400 miles. The dealership has attempted to fix the problem by replacing the fuse and control unit, but it appears to be a coding - programming issue. An engineering case has been opened for 2 weeks, but they have given me no notice of what or when the next step takes place.

I am filing a formal complaint against Lazydays RV (Tampa, FL) for repeat violations of NHTSA safety standards and probable violation of their 2022 Consent Agreement and Compliance Monitoring Order. In May 2024, I purchased a 2023 Mercedes-Benz Sprinter RV from Lazydays. The vehicle was sold as ânewâ and delivered to South Carolina. Upon delivery, I discovered it had been stripped of OEM parts and tampered with prior to shipment, including a non-OEM âTampa Bay Batteryâ substituted for the factory-installed Mercedes-Benz battery. That non-compliant battery failed in May 2025, leaving us stranded and requiring an emergency replacement. Lazydays also failed to register the…

Vehicle suddenly lost ability to accelerate. After driving narrow mountain roads with a lot of downshifting and upshifting, vehicle was on a long, gradual downgrade, then approached a long, slight (4%?) upgrade. Vehicle would not maintain speed and began to decelerate. Pushing the accelerator to the floor did nothing. Attempted to manually shift gears, but transmission would not downshift, or upshift. This almost resulted in being rear-ended by a semi. The speed limit was 55 and vehicle had decelerated to ~25 mph by the time I found a place to pull over. I stopped and was able to shift into Park. Revved engine and it behaved normally. I shut off engine for 1 minute and then restarted.…

I noticed there was a reall of the front hub assemblies, however my truck must not be on the list of vins affected. Iâm not sure where the problem originated, but I just passed over 20k miles and im experiencing signs and symptoms of what that recall would affect, this started a few weeks ago, not getting any better. It just stars vibrating and shaking pretty violently. like a wheels coming off. My father is also experiencing similar issues in is 2022 king ranch with 40k miles. Both trucks, very low mileage shouldnât show these sort of symptoms yet. Iâm not sure if they go hand and hand but it also disengages advanced track and all the front sensors and what not when it happens. After…
