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.

I am filing an urgent safety complaint regarding a defective Bridgestone tire on my 2021 Lexus UX250h, purchased new in 2021. At 32,000 miles, the [front left] tire shows abnormal tread tearing and separation, while the other tires show normal wear. This is not consistent with standard aging and indicates a potential defect and not normal wear. My attempts to Resolve it was following Bridgestone’s warranty process through Lexus and a Bridgestone dealer. Bridgestone dealer inspected the tire and blamed alignment, despite recent alignment and proper rotations done at Discount Tire Center on October 8,2025 and regularly. The wheel alignment did not show any tear. According to Lexus, Bridgestone denied the claim based solely on mileage without addressing abnormal tread separation (pls request Bridgestone response from Lexus). The tire poses serious and immediate safety risk of sudden failure, especially in rain, creating danger of a blowout, loss of control, or vehicle damage. I need to replace the tire immediately for safety. If your office requires inspection, please notify me as soon as possible so I can retain it. Tire info: Bridgestone Turanza EL450 BL 225/50R18 95V

225/50/18 Tires have less that 2000 miles on them and they are pealing at the treads. Literally whole chunks are falling off the tires…looks like someone has been picking and pulling off pieces of my tires.

ELECTRICAL SYSTEM

Some customers may experience operational difficulties with some telematics features which they cannot resolve on their own. These resources, in conjunction with the Repair Manual, are for dealership personnel to assist those customers with user issues, user errors, and compatibility issues with other vehicle systems and external applications encountered while operating telematics features.

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.
