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.

Toyota refuses to issue a recall for a well known issue with the UA80 transmission that fails around 5 years on many Highlanders. I follow [XXX] and there are countless posts about this issue. Mine failed at one month before my warranty was up and replacement was covered but it was replaced with the same transmission which I assume will also fail after 5 years or another 50,000 miles. There is a service bulletin for repair from Toyota so they're half admitting the issue but there needs to be a recall and a revision to the UA80 transmission to make them safer.
