Seems my car has developed some unusual vibrations that I can feel in both the steering wheel and in the seat. The vibrations occur while aggressively accelerating between 50 and 70 MPH, and while cruising at 85 MPH. I started noticing the issue with my previous tires and it has persisted to my completely new set of tires and across at least one annual alignment. I mentioned the problem to service about a year ago, they said they could not reproduce the issue. It was pretty subtle back then. Now it has worsened to the point where my passengers are commenting on the vibration while cruising at 85 MPH.
The feeling in the steering wheel is very subtle and vibrates at a rather high frequency, like a phone set to vibrate. I have a pre-AP car so no lane departure warning that could be the cause. Since it existed on a previous set of tires, I'll presume that it is not a balancing problem. When I had the newest set of tires put on about 15,000 miles ago, they were road force balanced to perfection. Still there was an issue, but I ignored it, thinking it was more or less in my head.
I'm taking her into service tomorrow, but was wondering if anyone might have some suggestions to help me point service in the right direction? Cracked motor mount? Cracked rim(s)? Half shafts? Axles? Bearings? Suspension components? Drive unit?
Tires were rotated two months ago at the same time an alignment was performed.
The fact that it happens in specific speed ranges points to a potential resonance issue, but again, it existed on a previous set of tires and I doubt it's balancing or the tire being out of round. It would be an incredible coincidence if it were either of those issues that happened to replicate itself on a new set of tires.
I'm currently at 68,000 miles and covered by the ESA. Thanks in advance for any guidance. I want to help service as much as I can in diagnosing the problem. I'll make sure I take a service technician with me on a drive so he/she understands and feels exactly what I'm talking about.
