Power Steering Light On problems of the 2012 Toyota Camry

First, the transmission is really jerk when accelerate at stop light. It also jerk really hard when down shift. It feels like the transmission is delay. Second, the electric steering wheel. The radio just shut off by itself and the steering wheel light came on at the same time, and then the light came off and the radio restarted by itself again. I feel like the electric has some problem.

While driving on a city street and turning, the steering suddenly "froze" (power assist failed) and a steering wheel warning light came on. Car was driven home and then towed to Toyota dealership for investigation. After investigating, it was found that the pig voltage was low (11 volts) and fluctuated while turning. Upon removal of lower dash and steering column, found no bolt in ground wire from emps ecu. Installed a bolt and resecured ground wire to instrument panel safety bar, and then voltage was normal and steering was normal during road test. Could not locate original ground bolt.

I was driving along at 30 mph when I herd a pop and the steering light came on the dash. The power steering quit I was in a lot of traffic with only arm strong steering. I got off the road as soon as I could and called the Toyota dealer I was able to drive carefully to get there. The dealer told me this was the first time they had seen this problem this could have caused a serious accident I would been going 65 or 70 and had this happen.

The contact owns a 2012 Toyota Camry. The contact stated that the steering warning light illuminated and the power steering failed. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure and current mileage was 45,000.

As I was driving 30 mph, my power steering warning light went on and my power steering failed. Thankfully there was no one behind me so I stopped my car and restarted it again. I was able to turn right onto a side street and then immediately it happened again. I pulled over to the side and parked my car. After a couple of minutes, I stopped the car and started it again and was able to drive it back home (less than a mile) without further incident. I immediately called my local Toyota dealership and they were very responsive to my concern especially since this could have caused a crash with my 4-year old child in the car. After I dropped off my car at the dealership, they ran an inspection and found a code c1554 power supply relay failure and replaced my power steering ecu assy. Although I'm glad this fix was covered under warranty, I will always have anxiety about it failing again especially since I've read other reports of steering failures in 2012 Toyota Camrys. Toyota says that this is the first line of Camrys with their eps (electrical power steering) system. With it being a new system for Toyota and based on the complaints I've read on 2012 Toyota Camry's eps, I urge a more in-depth investigation on this.
