There have been multiple accidents due to the electric p/s failing, including a near miss when my frail wife lost the assist. In my search for the cause, I have found that Lexus is replacing the entire steering rack as the "fix". Lexus is simply installing a replacement steering rack that has the same manufacturing defect as the original steering rack, costing some owners $1000 plus. After a few years, the replacement power steering rack will fail, just as the original did. When I purchased my Lexus, it was already 10 years old. That caused me to decide to find the cause of the p/s failure and repair it myself, if at all possible. Each time there was a failure of the p/s assist, I found that if I shut the power off and restarted the engine the problem would be gone. However,it was just a temporary fix. The more often the problem recurred, the interval between failures was less. I found that one particular electrical connector on the p/s rack has 4 very small pins in it. In fact, they are too small for the female part of the fitting. The mating of the 2 parts of the connector should have a snug fit. They don't! without a snug connection, oxidation occurs. That prevents the current from going through the connector as well as it should. Cleaning the connection will temporarily allow the p/s rack to function properly, but only until the oxidation recurs. De-mating and re-mating the connector will have the same effect. That will only work for a short period of time, eventually causing multiple failures in a single day. My repair was to snug up the 4 fittings by inserting a small strand of copper wire in each of the four female connections. It has now been 3. 5 months without a failure. Lexus should modify the faulty parts and initiate a recall before someone is killed!.

The electrical power steering failed. It's hard to make turn. Diagnositics indicate failure due to faulty electrical components. Asked Lexus dealer fix but refused.
