- 03VEHICLE SPEED CONTROL182
- 04ENGINE164
- 05FUEL/PROPULSION SYSTEM109
Owners report the steering wheel becoming difficult to maneuver, often at highway speeds, leading to diagnosis of a faulty steering column. This can be dangerous and expensive to fix.
Transmission failures are common, with reports of the vehicle no longer shifting gears or shaking violently. These failures often occur around 42,000 miles and can leave the driver stranded.
Complaints include sudden loss of power, blinking overdrive lights, and gas pedal issues. These problems can cause the vehicle to slow unexpectedly, increasing crash risk.
Some owners experience a 'Stop Safely Now' warning, especially in hybrid models, where the engine and electric motor shut down, causing immediate power loss. This is a serious safety concern.

Owners report sudden power loss, warning lights for brake and ABS systems, and rattling noises during acceleration. These issues can lead to dangerous situations on the road.
Complaints include simultaneous failure of power steering and braking systems, as well as TPMS warnings and tire failures. These electrical glitches can compromise critical safety functions.
Owners describe instances where adaptive cruise control and collision avoidance systems malfunction, sometimes failing to detect obstacles. This undermines driver confidence in the technology.
Reports include persistent sulfur odors and footwell obstructions that can trap the driver's foot. These seemingly minor issues can distract or endanger the driver.
