What actually goes wrong
The problems owners report
The most-complained-about systems on each vehicle — what fails, and what owners say in their own words.

- 02UNKNOWN OR OTHER699
- 03VEHICLE SPEED CONTROL633
- 04SERVICE BRAKES568
- 05ELECTRICAL SYSTEM556
Owners report issues with the lane departure warning and automatic emergency braking, often after software updates. Some say the system requires multiple service visits to repair, and a few mention hacking attempts, though these are rare. This matters because these safety features may not work reliably, potentially increasing crash risk.
Complaints include the main control unit going blank, causing loss of speedometer and adaptive cruise control. Others report software update failures that disable legally required functions for extended periods. This can leave drivers without critical speed information or assistance, making driving less predictable.
Some owners describe brake issues in low-speed maneuvers, like descending a steep garage ramp, where the car may not respond as expected. There are also reports of hacking that could affect braking. These problems are concerning because brakes are fundamental to safety, and any malfunction could lead to collisions.
The electrical system is a frequent complaint area, with issues ranging from software glitches to wiring problems in the rear compartment. Recalls include autonomous self-driving software and camera sensing system failures. These electrical faults can disable multiple vehicle functions and require dealer visits.

Owners frequently report warning lights for auto hold and electronic parking brake (EPB) shortly after purchase. Some experience high-voltage isolation faults (DTC P0AA6) that dealers may try to bypass. These electrical issues can lead to unexpected repairs and safety concerns if not addressed.
Complaints include unintended acceleration in reverse and loss of power while driving, sometimes with a bucking motion. One owner reported losing reverse and experiencing power fluctuations. These power train problems can cause loss of control and increase crash risk.
Reports include sudden deceleration and active high-voltage isolation faults. Some owners describe deceptive dealer practices to conceal these issues. Such faults can strand drivers or lead to expensive repairs, especially in electric models.
The auto hold feature may malfunction, displaying warnings and deactivating the electronic parking brake. Some owners report the car continuing to move after depressing the brake pedal. This is a serious safety concern as it affects the ability to stop the vehicle reliably.
