Hello everyone. I have a 2012 is350c with 41,000 miles on it. The car is hardly driven. But recently i have noticed a steering wheel jerking at low speed which goes from center to right, and then back, and keeps repeating. I also notice road noise under the car at speed greater than 55. The car had no issues, and not been in an accident. So I have no idea what the cause might be. Seems to actually get better after driving for over 20 minutes. Tires look good, not uneven wear on the tires. So lost as to cause. I read treads from other sites. But the steering on my car is electric, and not fluid run.

Any and all suggestions would be greatly appreciated. Our local dealer in my town, has not had very good reputation as far as service department goes, and a lot of cases on under handed dealings.

 

Have you ever had a wheel alignment?
