Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Dec 18, 2019
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

RAM recall #C4B, affecting ABS and Electronic Braking. Recall in effect, but no parts available for fix. This recall has been in effect for a few years. This vehicle is a 20000 lb motorhome, and my family's safety is being compromised by RAM dragging their feet and delaying the supply of replacement parts. I've contacted two RAM dealers and RAM Customer Service to no avail.

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.

Fire reported

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.

Manufacturer communications

A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.

SERVICE BRAKES

According to FCA Recall 24V896: "The brake hydraulic control unit could fail. Over time, this could cause the antilock braking system (ABS), electronic stability control (ESC) system and/or traction control not to work. An antilock braking system, electronic stability control system and/or traction control system that doesn't work could increase the risk of a crash."

PARKING BRAKE; SERVICE BRAKES, HYDRAULIC

According to the Interim Recall Notice Received by Mercedes-Benz concerning 22V796: "Mercedes-Benz AG has determined that on certain Sprinter vehicles, a component of the park lock system might wear extraordinarily due to specific driver parking practices and impair safe parking of the vehicle. If the vehicle is not properly secured in accordance with parking instructions in the operator's manual (including usage of the parking brake), it cannot be ruled out that the vehicle might roll away from its parked position under certain circumstances. Thus, the risk of an accident could increase. The driver will not receive a warning due to the nature of the failure mechanism. It is important that the driver ensures that the manual parking brake is engaged to adequately secure the vehicle against rolling away. Additionally, the parking level "P" is only to be inserted when the vehicle is completely stationary. The customer can find precise information on the parking process and on correct vehicle securing in their operator manual. Owners who notice any issues with the automatic transmission park lock function may contact their nearest Mercedes-Benz service partner immediately and have an appointment arranged for the vehicle to be inspected."

WHEELS

As per Mercedes Interim Recall Notice 21V042, one or more of the rear-wheel speed sensors may experience an electrical failure, which potentially could lead to a disablement of the Electronic Stability Control control unit functions. If ESP control unit functions are disabled, vehicle driving stability may be impacted under certain driving conditions, increasing the risk of a crash.

EQUIPMENT

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:GAS RECIRCULATION VALVE (EGR VALVE)

Daimler AG (DAG), the manufacturer of Mercedes-Benz vehicles, has determined that a defect related to a motor vehicle emissions control system may exist on certain Model Year 2016-2018 Sprinter models. Mercedes-Benz Canada Inc. (MBC) therefore has initiated a voluntary warranty extension related to the Exhaust Gas Recirculation (EGR) valve on these vehicles.

STRUCTURE

As Per Lippert Components; Specific 8800 Series windows installed in your recreational vehicle may potentially leak. The windows will be remedied by a Forest River Dealer.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
