The Power steering had started to feel hard and squeaking some time ago. I was driving day before yesterday and I noticed a few times that the steering was very difficult to turn which could have been dangerous. While doing some research I found that this has happened to some RX models. I went to the dealer and they told me that there is no recall for this issue and any fix would be out of pocket.

Steering column rattle noise on vibration while driving on uneven surfaces (like patched up or repaired roads, roads with gravel on it) or turning. This issue was listed in the L-sb-0026-11 but it is expired now. The stability may be affected as you drive over bump even on low speed. This issue affected a lot of cars and Lexus was replacing this part as mentioned in the bulletin. I acquired this car recently and it has the problematic steering wheel that the previous owner cared less to replace. I feel this part should be recalled as Lexus refused to take responsibility for this manufacturing defect (bulletin issued) when I recently contacted corporate office about it leaving me with $4000 repair on this low miles car for its age with that serious problem that is a part of suspension and vibrates and makes noises.

Steering wheel in 79,000 miles no accidents vehicle makes knocking noises as it jumps up and down (bumpy) or vibrates when driving over uneven roads (gravel). You can feel it in your hands. Also it rattles and makes noises when turning. It feels like there is no lubrication. The drive feels not only unstable but also is very distractive while driving. Took car to Lexus and was told it is steering column or shaft or both; quote around $4000 with labor. Seems like a lot of people had same problems and the steering is manufacturing defect that should be recalled. There was bulletin issued but my car is out of warranty now when the problem became prominent. There should be no time limit for that.

The steering lock actuator failed in the locked position while the vehicle was stationary. Although in this instance there was no safety hazard, it seems possible that this failure could have occurred while the vehicle was in motion, which would have caused the steering to lock and consequent loss of control of the vehicle. I informed Lexus us about this failure.

We bought a Lexus 450H 3 month ago. On last Saturday, when the car hit curb at starting speed, the steer wheel turns 90 degree. The left front tire has only very small impact, some dust mark can be easily wiped off. The car is still drivable, but we are afraid that this car may loss control very easily, especially when it is off road on bumpy road. Dealer is still talking with the factory to check whether the factory warranty will cover the damage.

Lexus hybrid SUV 2010 rx450H. Car was in snow setting and when I tried to brake on a light snow surface, there was no response from the brakes and I also was unable to steer. I continued forward until I reached clear pavement and was then able to brake. This happened 3 times today under the same conditions. Luckily no cars were coming or I would have been hit broadside on a busy street.
