We were driving on Rt. 32 north of Canaan Valley State Park in West Virginia. Suddenly the dashboard display began flickering on and off, displaying numerous multiple warning errors and alarms, and the windshield wipers began working and would not shut off. Turn signals would not function. Warning messages included instructions not to shift gears, lane keeping assist and automatic braking disabled, "Steering Malfunction", and many other errors. We have a partial video showing part on the incident. Dealer found evidence of corrosion on the Electronic Ignition System module, and sticking ignition on/off switch, which was indicated as the cause of the problem.

Mercedes Benz 3500 XL Sprinter motorhome, 2020 chassis. May 2023 MB did several recalls & software updates which MB USA headquarters said those changes could've affected the Cruise Control & Adaptive Cruise Control because these systems worked excellently until May '23, in my local MB Sprinter service. These systems have not worked more than 2% of the time. MB keeps changing items with no improvement. I told them to test on I-95 or The turnpike, as that's when we use it safely. Service tech said they're not allowed to test it there; we told them that's when it won't work, when we need it. Dozens of trips keep proving MB needs a permanent fix for the safety features we paid & need. I KEEP TRYING TO ADD MY 10 SECOND VIDEO CLIP BELOW BUT YOUR SITE WON'T TAKE IT. IT SHOWS the Cruise Control 3 blinking BLANK cursors on dash monitor where the mph Cruise miles #s setting should display. I showed this to my local MB service who sent video to MB USA HEADQUARTERS. Under my active Warranty they need to CHANGE the WHOLE CRUISE CONTROL SYSTEM. THESE bandaids are exhausting time & resources for all of us. Now their engineers say it could be the seat sensor. I've hamstring pain & need a seat cushion while driving. This EXCUSE is FAULTY like their FAULT CODES, as randomly I don't use my seat cushion & Cruise Control & thus Adaptive Cruise Control won't work. Thank you for your help!

The above are wouldn't allow me to place a check mark in the appropriate boxes. In the Standard Vehicle Components and ADAS sections, I was unable to check the boxes, but our vehicle contains ALL of the items in the first and second sections. The vehicle was dropped off at Lazy Days, Tampa on October 21, 2022 and so far they have been unable to provide an estimate or advise when we may receive our repaired motorhome. This dealer has a reputation for very poor follow-up. If you provide an email, I can send you the items to be checked. Despite going through two highway barriers at about 40 to 50 mph, the air bag system failed to deploy. The vehicle stopped as we ran into a fence at an angle of ten to fifteen percent. We luckily dodged five opportunities to be killed. My wife jumped out of the vehicle when it stopped and screamed so loud I could not believe it was her. I've been married 28 years and was shocked at her condition. I had to hold her to quiet her. The first hint of a problem was the brakes failed and the cruise control seemed to increase speed, but I'm not absolutely sure of this, but it felt like it. There are two Tiffin reps at Lazy Days, which I wrote about this, twice, and called leaving a message and they have not sought to get in touch with me. The supervisor, [XXX], of the intake service advisor, [XXX] said she would be in touch. I told her there was so much wrong, we understand if it took longer than her usual case. When it was about a month in, I called and discovered he no longer works there. They failed to assign someone to let us know of any progress. I called and left messages for [XXX] (Lazy Days employee) and wrote two emails and he also failed to get in touch, but he assigned [XXX] who called us asking what was wrong with our coach. I was beside myself. [XXX] failed to even read the invoice! I told her to read the invoice and call us back. Ran out of room.
