When driving the power steering will fail and lock up with out warning. You can turn the vehicle off. The computer resets and everything is normal only to fail immediately. This has happened at under 60,000 miles. Previous model years this was a recall. I believe I have a faulty part from the previous recall years. Not safe to drive.
Was driving towards a on ramp to a highway when the power steering failed. Service light came (service power steeling). Could still steer, but very difficult. Drove home and had it towed to dealer. They examined it the next day and found nothing wrong. Steering was now fine! two weeks later the same incidence happened while driving at 40 mph on a 4 lane city road. Vehicle is to be taken in this week for more testing of electronic ecm board. Even though vehicle is still drivable, it startles the driver and is very unsafe. Do not feel safe letting other family members drive vehicle or safe for trips.
