The 2004 Volvo XC90 has 3 recalls, the most serious being a potential fire risk from an overheating battery in vehicles equipped with a Garmin 760 portable GPS unit, and a brake and cruise control issue where a faulty front wheel speed sensor can trigger sudden unintended acceleration from a stop or low speed.
The wheel speed sensor concern appears across two related recalls. A defective front wheel speed sensor can send incorrect signals that disrupt anti-lock braking, engine management, transmission behavior, and the system that distributes torque between axles, reducing the driver's ability to control the vehicle during braking or cornering. In the more acute version of this defect, the bad sensor signal can cause the cruise control system to activate unexpectedly while the vehicle is stationary or moving slowly, causing the vehicle to accelerate without driver input.

What can fail
A faulty front wheel speed sensor sends wrong signals to the ABS and speed control systems, causing them to malfunction. This can trigger cruise control unexpectedly at low speeds, making the vehicle accelerate suddenly, or cause rough ride, transmission problems, loss of engine power, and unwanted spin control activation.

The dealer will replace the front wheel speed sensors with new ones.
