While driving between 60 and 80mph I go to accelerate and car feels like is shaking only while in that speed. Any advice what could be an issue? I recently had a problem with spark plugs and funny thing is it only happens in the C and S mode. Please advice, thanks!!!!!!!

Ok so I am experiencing the same thing with speeds around 75+. It's more a vibration like a bent wheel. I know it's not my wheels cause I felt it on my last three sets

I have heard others having the same issue also. Search on the forums and some have fixed it with an alignment and some with something in the steering column.

My car is lowered with rims and I am sure my dealer is going to blame the two. Need to return to stock before going in. Keep us posted


How many miles on your car

I only have 10k on the car

sounds like an alignment issue.

@drop - did you have an alignment done after lowering the car?

sebc63

It might be a tune. Went back to stock tune and theres no more shaking but i still wanna go back to a dealer to see if any transmission codes came up. Car is so much slower now without the tune.

Yes I did have the car aligned

This is interesting, do you mind telling us your tuner

Don't wanna put the tuner on the spot. Want to take the car to a dealer first and see if there s anything besides the tune that might be causing this. I heard some people with CLS had these problems which were caused by bad gas or some has some transmission codes pop up but it didnt trigger cel on. I ll post any info after taking car to a dealer next week.
