Default Vibration during acceleration (mavis mistake)

I have a 2015 wrx. Recently brought my car to mavis to have new tires and brakes done. During acceleration on the highway between 4th-6th gears I feel a slight vibration throughout and the exhaust sounds like I have the back window open, almost like a slight helicopter noise. Kinda reminds me of the sti rumble sound. I had them do my alignment as well.
So letís start off. They redlined my car. I had reset my boost gauge and when I picked up my car it was at 22 psi. I wanted to kill them. Anyway, I originally had bf Goodrich GForce a/s put on. They thought the vibration issue could have been that so they changed them for continental dws 06ís. I forgot to mention they damaged every rim so they had to go out for a powder coating. My tpms light still goes on and off as well. I checked my rims to see if they didnít have the hub rings which they did not of course. I got new rings which helped a bit but I still feel vibration under throttle on the highway. My concern is if itís a drivetrain thing. Iím beyond frustrated with mavis. Iíve gone back five times already and it seems nothing helps. They told me if they damaged anything they will have it fixed. I donít know how to proceed.

Between getting new tires put on, rims powder coated, then reprogrammed tpms(which didnít work). Yup The manager admits they completely ****ed up. Fired the guy who drove my car. Paid for my rims of course. Iím just concerned somethings still wrong due to the vibration and noise

Go to a competent tire shop and tell them exactly what you've told us. If they tell you something's wrong then have it fixed on Mavis dime. If there's nothing wrong and it's just the tires then you have a new problem.

Default Vibration during acceleration (mavis mistake)

Thatís the route Iíve been thinking of taking. At this point I rather pay someone else to have my alignment, etc done. My worries are more with drivetrain or engine troubles. I donít know if it was redlined like that with the engine cold. The motor sounds fine when I popped the hood and listened to it at idle and gave it a few light revs. There were no weird sounds that I could hear. Only issues are the ones Iím having while driving and were wondering if anybody would know what/where it could be related to.

If you are concerned about the douche that drove your car, get the car checked out by a trusted Subaru mechanic (including leak down test), or if your car is bone-stock, you can have Subaru do it. If there is a single thing wrong with the car, get a repair estimate and go after those SOBs.

My car is not stock otherwise I would have brought it to Subaru. I donít know any mechanics by me either. Iím absolutely frustrated. Could being out of alignment cause a noise that could be amplified by my exhaust? It sounds normal at low speeds but when Iím on the highway is when I hear it. Itís like the exhaust goes from a flat sound to a choppy wha wha wha wha sound. Lol. If that gives you any idea. But if I press the clutch in or pull it out of gear the noise stops. Thereís no loss of power or anything. Itís strange

Could be the differential or driveshaft? Also which mavis did you go to, guessing you are from NYC?

I understand how frustrated you are and how much this situation sucks, but I really think at this point you are making it worse than it is.

Redlining the car by itself isn't bad, your car has rev-limiter for a reason. It's not ideal to do it cold, but chances are they pulled the car in, put the tires on, and immediately took it out for a spin. I doubt this was a situation where the car was sitting for hours, then just started and abused like crazy. The oil and oil pressure probably wasn't ideal, but your engine isn't going to lunch itself from a few cold pulls.

We have no idea what he did to the car drive-wise, but if your tuner is even close to competent it really shouldn't matter. The point of getting a good tune is for situations like this, if your car breaks down from 3 min of abuse then there was probably a larger problem. If you want to go ahead and get a compression and leakdown test done as a precaution that's an option. But $$$$

You need to have someone get under the car and look at your suspension and differentials and what not. It's really obvious if something is puking out fluid or broken.


How many miles and have you done all your maintenance?

Does the sound change when you turn? If so it's a hub.

If its a vibration(car physically shakes) only under acceleration the. It is either a cv axle or driveshaft(unlikely)issue. To diagnose put it on a lift turn of traction control. Get a 36 inch pry bar rest it on the center of each cv axle while someone else accelerate i. The car. You will feel the vibration in the pry bar to determone which axle. My bet is the kid that drove it turned off traction and rev it up and dumped it. This is the only way to damage a cv axle. Balance of tires will vibrate all the time a certain speeds(not just under accel). Check control arm bushing and rear diff bushings if axles seem to be ok. Im an Ase master tech and have seen this before with younger techs "hot rodding" vehicles

I live in Putnam county which is an hour north of the city. I work in the Bronx where I see a million shops but not sure which is competent

Default Vibration during acceleration (mavis mistake)

Iím at work today and wonít be home til dark. Tomorrow morning Iím going to take a good look underneath to see if anything is leaking. I maintain the car pretty well. I have 45k on the odometer. Iíve changed plugs, diff fluid, trans fluid, oil change every 4K, etc. Come to think about it I have my winter tire set up on the stock rims. Iím going to swap them out tomorrow and take it for a ride just to rule out the tires and see if noise is still there. Thank you guys for the input

So I just got home. I definitely feel the vibration under acceleration/load. The noise seems to speed up or slow down with speed though

My vote is wheel weight fell off after the balance, or they were not balanced correctly to begin with when you got new tires.

I hope that is the case. First thing tomorrow morning Iím swapping my rims for the winters. If thatís the issue Iíll be super happy and never go back there even if I had a gun to my head. I was going to install my group n trans mount and bushings but that will have to wait

So just an update I swapped my rims and took the car for a ride. The vibration stopped but the whirling noise was still there. I noticed the noise stops when I turn the wheel to the right a bit.

Man, I know it looks ugly, but lead tape over wheel weights is the way to go in the case that they're not adhered to the wheel properly.

Think it's possible that the noise was always there but since you're pissed and worried about the car that you're listening far more closely now?

^^^Itís funny you said that. ^^^^ I was thinking the same thing for a second. But no, I have a thing with noise. My wife says Iím a little crazy when it comes to noises and I think sheís right. It drives me crazy. Anyway, the noise is new and definitely wasnít there before I originally went it. And like I said, I hear the differences when I slightly turn the wheel. Turn right, it stops, turn left, still noisy. My winter tires are quieter then the continentals I had on too. I donít get it

sounds now like a wheel bearing. as someone has said, while on the highway and upon hearing the hum, slightly turn the wheel to shift the weight of the car from side to side. If the noise comes and goes it could be a wheel bearing.
Mavis tried to screw me once but I called them on it and got reimbursed. That s another story.

there are other ways to check wheel bearing too (google it). Common and not a super big issue.
Sometimes when you put new tires you will hear things you didn t before because of the different (or less) tire noise.
