The steering system on my Lexus IS 350 F Sport malfunctioned while driving at high speeds on the highway. Specifically, the steering wheel locked up and would not allow me to turn, which made it extremely difficult and dangerous to control the vehicle. The car is available for inspection upon request. My safety and the safety of others on the highway were seriously endangered. When the steering locked up, I was unable to make necessary lane changes or navigate slight curves. I had to reduce my speed significantly...

and move into the shoulder lane as safely as possible. If I had needed to avoid an obstacle or make a quick turn, I would not have been able to. At this time, the issue has not yet been reproduced or officially confirmed by a dealer or mechanic, but I plan to bring it in for a diagnostic inspection. The problem occurred unexpectedly and without warning at high speeds, making it difficult to replicate in controlled conditions. I am currently arranging for the vehicle to be inspected by a Lexus-certified service center and will allow access to the vehicle for further investigation by the manufacturer or any other relevant party. There were no warning lights, error messages, or unusual noises prior to the steering failure. My friend owns an ES 250 and had the same issue a few years ago but was able to get it fixed via recall on his vehicle. My problem happened suddenly while driving at high speeds and was not preceded by any noticeable signs.
It was regular morning on memorial day and I had not used the car all weekend since I really dont drive unless it to and back from work. I started the engine like would any other day and the car began to shake out of nowhere. The check engine went off, the yield sign went off and the traction control went off. I thought maybe it was time to change my brakes because the dealership had recommended it. I changed my brakes and got new tires but the car still shook. I continued to drive like that to work because I had...

no choice it shaked mostly on idle and I drove like that for a few days on Friday as I was coming back from work on the freeway the car shook in the freeway as I exit out the freeway the car felt almost if I couldn't pick up an speed and I got extremely scared with the cars flying by. I decided not to drive and take it to a nearby mechanic I thought maybe the spark plugs or coils might be the issue but after 3 days in the shop and replacing spark plugs he confirmed it was the direct fuel pump and possibly the fuel injector....my car is only used to drive to and back from work and only has 58k miles. I believe this is a default manufacturer part and I need help recalling this particular part on my vehicle.
When driving on the highway for about 45 mins the steering will feel sticky or "lock up" and make changing lanes very hard. The steering wheel will be hard to move, and you have to "break free" which causes a very sharp lane change that you have to recorrect. This is not safe, others have reported the same issues on forums.
When driving at high speeds on the highway (75-85mph) after about 20 mins or so, the steering wheel feels like it locks up or gets stuck. The only way to get it back to normal is to jerk the wheel a bit resulting in swerving. This happens almost everytime I travel across the state. The car has passed all inspections at the Lexus Dealer. This past visit to the dealership, the tie rod was found to be corroded, however the technician does not believe that is the issue. We believe it is the steering rack. This car has...

not been in any major accidents and was having this safety issue prior to a slight fender bender. The issue is a huge safety concern because the steering wheel "stops respondings" and needs to be jerked or swerved to go back to normal.
