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.
0
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.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

Filed Jul 2, 2026

The contact owns a 2020 Forest River Dynamax Isata 3 built on a 2018 Mercedes-Benz Sprinter 3500 chassis. The contact stated that the TPMS was malfunctioning and failed to provide accurate readings for all tires, with the alarm sounding. The vehicle was taken to the dealer, but the cause of the failure could not be determined. The contact became aware of Forest River Technical Service Bulletin: 55-1097. The contact stated that the manufacturer had previously failed to disclose that there was a TSB related to the failure. The vehicle was taken to the dealer, who advised the contact that the VIN was not included in a recall associated with the failure. Additionally, the dealer informed the contact that the manufacturer had advised that the vehicle was not eligible for the TSB repair. The contact was advised that the repair was previously performed by the Mercedes-Benz manufacturer. The contact called a Mercedes-Benz dealer, who advised that the TSB repair was not completed by Mercedes-Benz because it was Forest River's responsibility. The contact returned to the Forest River dealer, who informed the contact that the manufacturer had approved the repair, but the wheel band sensors provided by the manufacturer were incompatible with the Mercedes-Benz Chassis. The dealer then took the RV to a tire repair shop, which had the same Forest River parts and confirmed that the parts were incompatible. The vehicle was taken to Laird Noller RV Supercenter (5332 NW 24th St, Topeka, KS 66618), who advised the contact that the compatible parts were available, but Forest River had denied coverage for the TPMS and new wheel band sensor installation. The manufacturer was not contacted. The failure mileage was approximately 1.

SERVICE BRAKES, HYDRAULIC

FCA US has decided that certain vehicles fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) No. 106 - Brake hoses. Constriction requirement states, "Except for that part of an end fitting which does not contain hose, every inside diameter of any section of a hydraulic brake hose assembly shall be not less than 64 percent of the nominal inside diameter of the brake hose." Brake hoses that have an out of specification orifice diameter have an inside diameter that is less than the 64 percent requirement.

WHEELS

The flanged wheel lug nuts on your vehicle may have been over-torqued during service to an incorrect torque specification in the Service & Owner's manuals. A yielded wheel stud may eventually break, which could lead to a wheel separating from the vehicle during operation. A wheel separating from the vehicle could cause a vehicle crash without prior warning and/or the wheel/tire could pose a risk to other vehicles or pedestrians.

ELECTRICAL SYSTEM; ENGINE; POWER TRAIN:AUTOMATIC TRANSMISSION

Per FCA’s Recall 21V439, the engine calibration software may not warn of low oil volume.

511368

POWER TRAIN

The transmission control module software in your vehicle may cause the transmission to slip or will not go into gear at all. In addition, the Malfunction Indicator Lamp (MIL) may illuminate on the cluster.

511362

SERVICE BRAKES

The retaining washer and bolt that connect the brake pedal to the bearing block may come loose and detach. This could cause the brake lights to stay illuminated, even when the brake pedal is not pressed.

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.
