What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The backup camera system malfunctioned, resulting in a blank or distorted display screen when the vehicle is placed in reverse. This system failure deprives the driver of rear visibility and disables the rear parking collision warning, creating a safety hazard when backing up.
The contact stated while parked and occupied in the vehicle or driving the contact noticed the headlights have failed to work as intended. A dealer was contacted. The vehicle was taken to the dealer where it was diagnosed that the headlight assembly needed to be replaced.
The car presented with several issues including, difficulty starting, engine misfires, stalling, and decreased fuel efficiency. The low fuel warning light on my car's dashboard would not come on when gas was low at all, until it left me stranded in the freeway far away from home and a dealership.
Chrysler 300 2021 Vehicle keeps stalling, turning off while driving or if stopped at light or stop sign to loan just shuts random times and not Al way but enough to be dangerous when it stalls on freeway or in traffic Seat belt Driver seat belt just broke, split in half- safety issue.

Thye just keep saying they dont have a fix for it. Well, thats unacceptable I have myself and small kids that have to ride in amunsafe vehicle.
My car turns off periodically while I’m driving and when I’m stopped at a light. This is random, so I didn’t even go on freeways from fear the car will stop suddenly in heavy traffic and I be killed or injured badly I have taken it to the dealer and they keep saying nothing is wrong, last time they kept car for 3 days…
About 2 months ago the passenger seatbelt in my vehicle just tore out of nowhere. The seam seemed to unravel and it completely broke. Took it to get repaired had some issue but my complaint today is to help save someone from this or maybe others may have had same issue. The seatbelt was poorly made or defective.
