I lost power steering while driving 70 mph on a two-lane highway in Wyoming. There were no warnings before the incident, but a Service Power Steering light came on at the same time it quit working. One mechanic shop did a diagnosis on the car. I was told that the Electric Gear Power Steering Motor needs to be replaced along the whole Rack and Pinion that it's attached to has to be replaced because of the way it's designed. I found out that 2,000 of these same model and year of cars had a recall on them for this exact problem, but my car's VIN wasn't included in that recall. After doing thorough research on the internet, I have found that this is a common issue with these cars, and it's obvious that the manufacturer should have included more cars in the recall. I have just turned 77,000 miles on my car, and I have been given a $4,000 estimate to get it repaired. It is completely undrivable at this time.

While driving at highway speeds (65+ MPH) the information center will display 'reduced engine power' and car will down shift and only reach 45 MPH. Causing close to rear-end crash. You have to leave the highway traffic immediately and turn off engine. Re-start engine and continue driving. It has happened twice now. Seems like a software problem.
