Austin - have you had tires swapped? I had 2 defective sets of the Michelin MXM4s. I finally had them swapped with Conti DWS 06, and it's smooth as silk now.
If your dealer has a car on the lot with NO vibration, ask them to do a temporary swap of wheels and tires to your car, and see if the problem goes away. That is how my tech approached the issue. Drive a stock unit ---> verify no vibration ----- > swap tires to your car -----> Check for results.
Just a thought. Don't take.. "we balanced them and they are in spec" for an answer.
Hello jsmit86,
Thank you for your thoughts and suggestions. I agree that
"we balanced them and they are in spec" certainly doesn't cut it, as that was done three times before. I just got my car back this afternoon. The dealer claims they swapped wheels/tires from another vehicle weeks ago, after which my car still exhibited the same issues according to them. They then proceeded to try two other things based on the Hyundai service hotline suggestion (not sure what that was, as it was weeks ago and I didn't take notes) - no change. Not sure what they did, as I don't have the paperwork yet (they'll mail it).
Apparently Hyundai finally sent someone out on Wednesday, they replaced all tires on my existing wheels, did a road force balance (or road load balance, not sure I remember correctly) and the Hyundai engineer was satisfied that my car is OK now. I drove it home and it's a lot better than what it was before. I do have a new set of Michelin tires (the service advisor said same type as the old tires) on my car now, and they washed and detailed my car and had it ready for pickup this afternoon.
I only put about 20 miles on the car so far - after almost five weeks I had to reacquaint myself with some of the features (makes me feel like I'm getting old). After all the time in various rental cars, I appreciate the engine power (I "only" have the V6, still miles better than the 1.8l non-turbo in the Chevy Cruze and whatever is the base engine in the Sonata - maybe a 2.4l?), the quiet ride, the seat and the stereo system in my Genesis. I missed the ACC, LKA, BSM and various other goodies in my car, the HUD is the thing I probably missed the most.
What remains is a terrible vibration at idle (in the seat and steering
wheel), and some annoyances that would require Hyundai to reprogram the car from the factory (like default sport mode, default auto hold on, default ACC on, default seat cooler on - it was 78 today, and after the car was parked in the sun the seat cooler was really nice).
Five weeks to fix a known issue (plenty of posts here on the forum about vibration issues) is not acceptable, especially when they pay for a base model Chevy Cruze rental car for the duration. I'll see what Hyundai corporate is willing to do to compensate my for the time without my car ...
Thanks again for your advice, it turned out to be 100% on point!
