Owners report that the automatic emergency braking and lane-keeping systems can behave unpredictably, sometimes requiring repeated service visits. Complaints mention software updates that disable or degrade these features, which matters because they are marketed as safety aids.
Drivers describe the main control unit going blank, causing the speedometer and adaptive cruise control to stop working without warning. This can leave you without critical driving information while moving at highway speeds.
Some complaints involve braking issues in low-speed maneuvers, such as descending a steep garage ramp, where the car may not slow as expected. Brake problems are always a serious safety concern.
The electrical system is a frequent complaint area, with reports of software failures that disable legally required functions for extended periods. These glitches can affect everything from displays to charging.

Owners report sudden engine failure warnings, jerking, and popping noises, sometimes within hours of leasing. These issues can leave the car undrivable and require major repairs.
Complaints include persistent battery drain that makes the car inoperable, sometimes stranding owners far from home. Electrical gremlins can be hard to diagnose and costly to fix.
Reports include door seals detaching and water entering the cabin, as well as panoramic sunroof glass shattering while driving. These defects can cause leaks, electrical damage, or injury from flying glass.
While fewer details are given, this area appears in the top complaints, suggesting fuel delivery or propulsion issues that can affect performance and reliability.
