The failure pattern owners describe
Owners of the 2021 RDX cite a clear pattern of rear windshield spontaneous shattering. Reports come in across a range of mileages—from under 6,000 miles to 75,000—with glass breaking while the vehicle sat parked in driveways, during door closure, or during startup. No external impact precedes the failures. Glass shards scatter into the cargo area and trunk. Multiple owners note the dealer acknowledges this happens frequently and that neighbors and acquaintances have had identical failures. A manufacturer TSB (22-014) exists for rear windshield glass shattering, but one owner was told the 2021 model year is not covered; warranty denial and extended repair wait times (3–4 days quoted) are common complaints.
Visibility problems extend beyond the rear glass. One owner's windshield washer pump failed and was replaced, but nozzles remain clogged and are on critical backorder—leaving the owner unable to clean the windshield while driving. Another owner reports wipers stopping completely for hours or days at a time, happening multiple times over ownership.
One complaint also involves the adaptive cruise control system braking hard on its own while the vehicle is in the passing lane at highway speed, with no vehicle ahead detected. The owner reports this has occurred roughly once every three weeks.
