DYNAMAX Complaints

Exterior RV retractable awning (model = Latitude) manufactured by Carefree of Colorado and installed by Dynamax Corporation on the Isata 3 models. Several RV owners are reporting that the awning pitch adjustment locking screws are missing on their Isata 3 vehicles. These pitch adjustment screws are "pitch locking" screws, yet neither Dynamax Corporation (responsible production and installation of Carefree Awning installation) nor Carefree https://www.carefreeofcolorado.com/ have addressed this HIGHWAY SAFETY issue! It is not rocket science that an RV manufacturer should consider this EXTERNAL RV component missing part a HIGHWAY SAFETY concern! This was discovered by checking our Isata 3 after reading other owner's posts on a Facebook Owners Group for Dynamax Isata 3.

I purchased the brand new 2023 Dynamax Europa 31SS on May 20 for the dealership. When driving it home on the highway I experienced loose steering controls, pulling to the right and the steering rod clunking inside the steering column. It was difficult to maintain my lane of travel especially when going over small bumps or negotiating bends in the road. The highway was a flat, paved two-lane divided road and it was dry, clear and there was no wind. I experienced a sudden strong pull to the right and the motorhome veered sharply towards the ditch while on a straight roadway. When I tried to correct the steering it was loose and unresponsive, then suddenly oversteered to the left. This caused the motorhome to rock from side to side and nearly roll over. Thankfully due to 16 years of law enforcement highway patrol experience and driver training I managed to gain control and slow the motorhome. This would have been a serious injury or fatality roll over. The vehicle cannot be safely driven in excess of 50 - 60 mph. A journeyman heavy duty mechanic did a brief inspection and immediately found a rear axle and frame issue. A test drive identified loose steering, inexplainable clunks within the steering mechanism and a strong pull to the right at low and highway speeds.

The ABS (anti lock braking system) module failed resulting in ongoing beeping with display warning to service the system, and intermittent failure of other electrical features. A local mechanic diagnosed the problem and recommended replacement of the module. The Dynamax RV is a coach built on a Ram 5500 chassis. I was able to obtain a new replacement ABS module, but then learned that it had to be installed and "flashed" (programmed) by a dealer. I contacted Dynamax (now owned by Forest River), but have not received a reply. I then contacted the five nearest Ram dealers in my area. All of them told me that they could not help me because my vehicle is too big for their shop. I don't know if this problem affects my braking , but it appears that I am stuck with no solution. I hope you can help me. Any help would be appreciated.

Tire Pressure Monitoring System is very unreliable. Right rear wheel rarely reads. TPM readings are typically off by over 10psi verified with calibrated gauges when cold.

Valve stem on inner rear Dually tire was delivered with a loose nut causing it to loose air.

Constant Electronic Stability Control failed not allowing use of adaptive cruise control

Traveling on a busy interstate, traffic limited to one lane because of construction. Traffic stopped, instructed by law enforcement to turn off vehicle to wait. Shortly after, traffic started moving but our vehicle would not start. After stopping traffic for about 15 minutes the vehicle finally started. Incident repeated at a gas station, stopped for gas, filled up, when complete would not start, once again after 15 minute wait it started. Dealer unable to get the problem to repeat. Onboard diagnostic computers didn't record the fault. Mercedes Benz corporate will not do anything to assist getting the issue fixed until repeated by the dealer. Researched online and found video of someone else with exact problem and solution. Many comments of others with same issue. We have owned this vehicle for about 500 of its 10000 miles.

I HAVE HAD 2 FRONT WHEEL SIMULATORS SEPARATE FROM THE WHEELS WHILE OPERATING SAID VEHICLE AT HIGHWAY SPEEDS. PRIOR TO EACH TRIP I PERSONALLY INSPECTED THE WHEEL SIMULATORS FOR PROPER ATTACHMENT AND SECURITY. MY CONCERN IS THE HAZARD THESE FAILURES TO OTHER MOTORISTS ON THE HIGHWAY AS WELL AS THE EXPENSE OF REPLACEMENT. DEALER SHIP PARTS CLERK STATES ( OFF THE RECORD) THAT THEY SELL APPROXIMATELY 50 OF THESE WHEEL SIMULATORS PER YEAR.

THE POSITIVE BATTERY CABLE FOR COACH BATTERIES FELL ON TO THE DRIVE LINE AND STARTED A FIRE WHICH MELTED THE ANTI-LOCK BRAKING SYSTEM AND CAUSED FURTHER DAMAGE UNDER THE COACH. THE FIRE WAS PUT OUT VERY QUICKLY AT THE SHOP WHERE THEY WERE GOING TO HOOK UP A TOW BAR ON THIS NEW RV. (THEY HAD FULLY PREPARED THE TOW VEHICLE AND THIS WAS TO BE THE FINAL STEP) IT IS UNKNOWN WHEN THE INCIDENT BEGAN TO OCCUR BUT THE FIRE MOST LIKELY STARTED AS THE RV WAS BEING DRIVEN FROM OUR HOME IN MEADOW VISTA CA TO ONE STOP TRUCK SHOP IN SACRAMENTO CA. THE FIRE STARTED A FEW MINUTES AFTER THE RV WAS PARKED IN THE PARKING LOT AND MY SON HAD LEFT THE SCENE. A POTENTIALLY DEADLY PROPANE AND DIESEL FUEL EXPLOSION WAS AVOIDED BY THE QUICK AND DECISIVE ACTIONS OF THE OWNERS OF ONE STOP TRUCK SHOP. THE FOLKS WHO SOLD US THE RV MENTIONED WE'D PROBABLY LEFT THE PARKING BRAKE ENGAGED WHILE DRIVING ... WHICH WAS UNTRUE AND COULD LEAD TO FURTHER DENIAL OF A MAJOR ISSUE THAT COULD HAVE BEEN DEADLY TO THE OCCUPANTS AND ANYONE WITHIN THE DISTANCE OF WHAT COULD HAVE BEEN A PROPANE AND DIESEL FUEL EXPLOSION. TO THIS POINT, EVEN THOUGH CLEARLY A WARRANTY ISSUE, BOTH FOREST RIVER AND DIMARTINI RV THEY HAVE MADE NO ATTEMPT TO RESOLVE THE ISSUE EVEN THOUGH THEY HAD THE COACH AT THEIR SHOP FOR SEVERAL DAYS. THEY DEMANDED WE TURN OVER TO INSURANCE EVEN THOUGH THE COACH IS UNDER WARRANTY. EVENTUALLY THE INSURANCE COMPANY TOWED THE COACH TO MERCEDES BENZ OF ROCKLIN CA WHERE THE TECHNICIAN CONFIRMED THE DANGEROUS AND POSSIBLY DEADLY ISSUE.
