The engine coolant can leak into the exhaust because air a known design flaw. When the the engine turns on after being in electric mode the coolant pump starts and pushes it out the exhaust causing a sudden over heating of the engine. This causes the car to stall and can be very dangerous at freeway speeds.
Installing a car seat and the belt buckle failed. The plastic part split and no longer holds the belt together. This was under regular pressure with standard leverage that the car seat design calls for. Nothing was ever on top of the buckle and it is not damaged in any other way at all other than the failure. They refused to replace it via warranty.

The vehicle was returned with the hold-down bracket unsecu…

Source: NHTSA Office of Defects Investigation public data (complaints, manufacturer communications, investigations), model years 2010 and later. Had a safety problem? Report it to NHTSA.
In complaints filed with NHTSA for model years 2017–2022, owners most often name: electrical system, power train, forward collision avoidance. 27 complaints are on record.
No. A complaint is an unverified report from an owner. A technical service bulletin (TSB) is the manufacturer telling dealers how to fix a known issue; it is not a safety recall and is usually covered only under warranty. A recall is a formal safety action, and its repair is free.
File a vehicle safety complaint at NHTSA.gov. NHTSA reads every report, and patterns of complaints are what open defect investigations and, eventually, recalls.
