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 Sep 20, 2023
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.

Manufacturer communications

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

CSA-045

FUEL/PROPULSION SYSTEM

Tiffin sent out an addendum to be added to Owner's Manuals that states, "Tiffin Motorhomes recommends that all diesel units be refueled using standard automotive-grade diesel fuel pumps, rather than high-flow commercial truck stop pumps. The fuel delivery rate from commercial truck stop pumps is often too aggressive for motorhome fuel systems, which are not designed to handle rapid fuel intake. Using high-flow commercial truck stop pumps can result in overflow, spillage, premature shutoff, or even damage to the fuel fill components."

MCD-009

EXTERIOR LIGHTING

Stopped using the lights we had been using due to expense. Replaced with these, but these new lights have to be wired in instead of just clicking in. These are the instructions to wire in.

CSA-036

ENGINE AND ENGINE COOLING

Faulty DEF sensors that due to shortage were not replaced. Instead engine software was temporarily modified to account for continued operation with a faulty sensor until replacement sensors were available. This campaign will install an engine control module calibration as well as confirm and/or install a new DEF header.

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.
