“Toyota has known of this problem for years and has worked on the car last year to give a temporary fix, now a few months ago Toyota sends yet another recall for same parts, but yet the dealers nor Toyota has any idea of when this will be available, meanwhile we drive around in fear of unnecessary deployment of airbag.

NHTSA complaint #10721395, filed 2015-05, 75,000 miles“On this date the car was recalled for a steering column upper bracket replacement. Today march 19th, we took the vehicle to our regular mechanic for front brakes and to check because the key will come out of the ignition when the car is turned off and in drive or reverse rather than park.

By the time I signed all of the paperwork and took possession of the car, it had become dark outside. The display of gear positions (p, r, n, d, 2, l) which was obvious in daylight, was now impossible for me to distinguish. By the time I arrived home, my eyes were strained from trying to read the letters, thus creating a hazardous driving experience.
