Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
511628B
According to DTNA Recall FL969/23V237: "On the affected vehicles, the spline teeth in the windshield wiper arms may wear and break. This can cause the wipers to fail, reducing the driverâÂÂs visibility, and increasing the risk of crash."
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
