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 “new” 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 “Tampa Bay Battery” 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 manufacturer’s warranty with MBUSA for nearly one year, preventing factory coverage during that time. I later obtained confirmation from the RV manufacturer (Thor Motor Coach) that the vehicle was missing several required OEM components (bike rack, ladder, seat and door covers), and they were forced to replace these at their own cost — not Lazydays’. The dealership also collected $1,600 in SC registration/title fees, then failed to perform the service or refund the charge. This case reflects a pattern of deceptive delivery, false documentation, and equipment tampering, all of which directly impact vehicle safety, warranty integrity, and federal compliance. Lazydays’ behavior is consistent with violations described in their 2022 NHTSA Consent Order. I am formally requesting NHTSA investigate this matter as a repeat offense under active probation and compliance oversight. Please initiate a formal compliance review of Lazydays RV under its existing NHTSA oversight. This is no longer a single instance — it is a persistent pattern of regulatory violations that impact consumer safety and vehicle compliance.

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. Transmission and all other systems worked fine and continued to work normally for several hundred miles since then. There was no CEL, or other warning. There was no indication that it entered "Limp Mode." I suspected that something went wrong with the logic in the electronic transmission. Mercedes Benz dealership could NOT find any codes logged in the OBDC. The service manager told me, "It might have been some kind of computer glitch." This was a 2-lane, country road. The semi was behind me, and several cars were behind the semi. For about a mile there was no place to pull over. One impatient driver passed both the semi and my Sprinter in a "no passing" zone. We were all fortunate that there was no collision.

The vehicle was not repaired. The contact independently had samples of the diesel fuel tested and no water or contamination was found. The contact stated that the Insurance provider also tested the diesel fuel and found no contaminants or water. The contact researched online and related the failure to a diesel filter design for the year, make, and model. The manufacturer was informed of the failure.

I noticed there was a reall of the front hub assemblies, however my truck must not be on the list of vins affected. I’m 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 shouldn’t show these sort of symptoms yet. I’m 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 reading a few articles I do not feel the truck is safe on the road until probably inspected.

I was driving my van and out of nowhere it locked up and power steering malfunctioned. I was in NY at the time. Tried to get MB to help explain what was happening. Said they would send a Tech out. Found out they were going to send a tow truck and that was it. I had several pups on board and had to get them safe. So I figured out how to drive it with no power steering all the way back to Houston. While driving we got into some rain. Which for whatever reason the rain kicked the power steering on for just 5 or less seconds. This kept happening on and off while in wet road conditions. I was freaked out as the change made the steering go from impossible to beyond sensitive. We could have so easily flipped had I not been paying attention and driving at a slow speed. This also made all the safety features not accessible. No blind spot, cruise control, lane change or any of the important functions this van is equipped with. I would like to note that MB had to replace the engine due to a defect. Took 4 plus months. I have had issues ever since. Engine light came on all 4 of my trips. I know one that was the reason is VOX sensor. Fixed it and then happened next trip. Plus other sensors replaced. This van has been horrible! Bought it and was told they run up to 500k and these new engines they expect to see a million miles. I can’t even get it to 100k I called MB USA and started a complaint. They acted concerned and would contact me within 48 hours. Never to hear back from anyone. This was the same response when the engine malfunctioned. I was going to be given a loaner van and never heard or could connect with anyone.

Emergency brake assist, distance sensing and adaptive cruise control randomly and intermittently deactivate while driving. In a recent 8-hour highway trip this deactivation occurred 7 times, sometimes correcting itself with no driver intervention, and other times remaining disabled for hours and hundreds of driving miles. Durning motor off and restarting occasionally reset the issue, but many times it did not. When these systems disable, the van’s speed rapidly decreases and may cause other vehicles to hit the rear of the van, or cause van drivers to panic and/or lose control of the vehicle. Random and unpredictable electronic failures such as this are a definite hazard and need to be addressed by the manufacturer.

2018 Cx-9 GT that has experienced spider cracking in the upper right corner of the infotainment screen (the cracks are inside the screen). This started after the car sat at the dealers lot in cold temps while waiting for repairs to the engine Feb 2022 (mileage on car at that time as about 36K). Mazda had issues a Service Alert on 2/20/18 in regards to this issue for 2016 - 2018 CX-9's (along with other model of similar years). No mention to me by dealer (who i have taken car to for all service matters from 1st day of purchase). Mazda then issued a Warranty Extension Program letter dated 5/06/20 to Dealers, Service & Parts Manager that they would extend warranty coverage to fix this issue, but only for 2016 & 2017 CX-9 vehicles. Over time the cracking has gotten worse & is slowly growing in size. (some other owners have it cracking in different parts of screen, which renders the touch screen useless). Mazda should include 2018 in the Warranty Extension Program, so this issue can be resolved for all years affected.

This vehicle is extremely unsafe to drive. Vehicle is currently being rented. All four adjustable coil-overs’ springs have been heated in efforts to lower the vehicle. The person who performed this may not have understood that the car height could have been adjusted without heat. I have supporting documentation in form of photos and video informing the current renter who still drives the vehicle as of today. It is imperative that my information is not forwarded to the current owner or driver as there are criminal charges being brought against the renter for multiple counts of 3rd degree felony which include defrauding victims out of millions of dollars. My name along with this statement should be protected from the vehicle owner and current driver. The manufacturer may have my information but should also be informed to keep my information private for the sake of my safety. Thank you.
