clarification 6/3/2021, 9 p.m.: this story has been updated to add further details from nhtsa's report as to the nature of the potential problem.
tesla is recalling just under 6000 model 3 sedans and model y crossovers for loose brake caliper bolts that might disassemble and cause low tire pressures. the recall affects model year 2019–2021 model 3 and 2020–2021 model y vehicles.
a recall report submitted by the national highway traffic safety administration (nhtsa) states that the brake calipers are secured using two fasteners and that they might come loose over time if not secured properly. according to nhtsa, if a caliper were to "[make] contact with the inner surface of the wheel rim, the wheel may be prevented from freely rotating, which may cause loss of tire pressure," meaning the tire is likely to drag along the road until it pops and loses air pressure. nhtsa's report says that owners might be able to hear the caliper making contact with the wheel. the agency is not aware of any accidents or injuries related to this issue.
late last year, tesla was notified of a 2021 model y that had a missing bolt on the driver's-side rear brake caliper and reviewed its production torque specifications. the automaker adjusted its production process to deal with the issue, according to nhtsa documents.
tesla has not yet said when or how it will notify owners of affected vehicles, but it will tighten or replace the bolts for free. meanwhile, owners can contact tesla customer service here or check the nhtsa recalls site to find out if their vehicle is involved and to stay informed.
