The 2004 Volvo V70 has 3 recalls, the most serious being a driver's airbag inflator that can explode during deployment, sending metal fragments into the cabin and risking serious injury or death.
The front suspension also has a structural concern: the lower control arms may not meet manufacturing specifications, causing the stud and nut that attach the control arm to the wheel spindle to lose tension over time. If that connection works loose far enough, the control arm can separate from the spindle entirely, leaving the driver with little ability to steer or control the vehicle. On the engine side, a faulty fuel pressure sensor can send incorrect readings to the engine's computer, triggering misfires and a sudden loss of power. In the worst case, the engine can stall without warning while the vehicle is moving, leaving the driver with no throttle response until the engine restarts.
