User Complaints and Problems
Mechanical Problems
- Fuel and propulsion system - User complaints report a dropped down fuel efficiency with the sedan. This violates the official manufacturer’s claims of the on-paper fuel efficiency figures.
- Brakes - The car comes across a few complaints regarding the braking system. Users report instances wherein the car speeds up on depressing the brake pedal. This results in the crashing of the vehicle. Braking defects compromise the safety of the car and its occupants. This increases the risk of crashing or injury.
- Engine - Engine issues are common with the sedan. Multiple cases report shredding of the drive/serpentine belt. This results in a squealing noise while driving and idling. Few cases also report instances of snapping of the serpentine belt. This can result in engine stalling. The fix to these issues needs the users to replace the serpentine belt frequently. Engine issues increase the chances of a crash.
- Vehicle Fire - The records report a one-off case of engine fire with the car. The user reports the car abruptly slowing down followed by the emission of white smoke from the hood. This progresses to an engine compartment fire. This eventually gutted the vehicle and results in a total loss of the vehicle.
Electrical Problems
- Connectivity - User complaints report that devices connected to the car’s BlueTooth intermittently disconnect. A repeated disconnection of devices may distract the driver.
Safety Problems
- Airbags - A few users report cases of intermittent airbag malfunction warnings on the dash. A loss of drive power and engine stalling follows this. The warning can distract the driver while driving. A sudden loss of drive under driving conditions increases the chances of a crash.
- Backup Camera - User complaints report instances of the backup camera failures. This leads to a loss of rearview backup camera display graphics. A lack of a rear-view image increases the chances of a crash.
Structural Problems
- Taillights - Users report that the tail lights do not illuminate brightly while driving in dark. This leads to dimmed brake lights. This can make it difficult for the tailing motorists to acknowledge braking. This increases the chances of rear-ended collisions.
- Wheels/tires - Despite factory stock-fitted run-flat tires, the sedan is prone to frequent tire blowouts. Users report multiple cases of tire blowouts under driving conditions. This increases the risk of crashing for the occupant as well as fellow motorists.
