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.

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.

Reports submitted to NHTSA, shown in the owner's own words

Incident

Fuel system
Filed Aug 26, 2021

Issue 1. RV plumbing system poorly designed and installed allowing Grey-water tank damage and unsafe and unsanitary sewage leak. The Grey-water tank was not engineered with close enough tolerance in the mounting structure to prevent shifting during normal driving conditions allowing the tank to uncouple from the mounting rails, breaking the plumbing fixtures and allowing sewage to spill in the plumbing compartment. The tank was also engineered without a support structure under the tank as a supplemental support. The authorized dealer diagnostic inspection and estimate of repair supports the lack of engineering standards. Issue 2. The on-board generator system fuel lines are routed over the top of the chassis lead-acid batteries. This is not logical, safe or prudent. In a collision, a battery short could cause a catastrophic fuel-fed fire.

SUSPENSION

Freightliner Chassis - Detroit Diesel Corp Field Service Campaign D19M4 - Different I-Beam design was introduced on the axles that does no have a flat mating surface on the bottom side of the I-beam where the optional stabilizer brackets are mounted. This may result in damage to the stabilizer bracket due to bending stress during assembly of the U-bolts. Inspection of the stabilizer brackets and I-beams for damage may require installation of spacers and replacement of the stabilizer brackets and mounting hardware. A Detroit Diesel Authorized Repair Facility will perform this service at no charge prior to September 26, 2020.

EQUIPMENT

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.
