Official summary
Some vehicles may exhibit windshield glass distortion or a double-image from the active driving display. These may be due to a) distortion in the windshield glass not properly removed during the manufacturing process or b) glass with incorrect specifications used in the manufacturing process. To eliminate these concerns, the windshield glass manufacturing process has been modified.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
