Car seems to 'fish tail' / unstable after alignment?

[srahmed87]

Hi all,

Last week I took my car (3.3 G70 2019) for servicing. They said the alignment was off through their machine and afterwards, when driving, I could feel the car "kicking out" or some slight instability when accelerating.

Its mostly after accelerating (even at low speeds) and then letting off on the gas it kinda 're-aligns'.

I went back to the dealer and dropped the car off. The service tech said everything was fine with driving. I came back and took the service manager in the car and pointed out what I felt. He agreed that he felt that. The service tech went in as well and felt it also and said 'normal variant... RWD car etc".

My car has 18k on it and I never felt anything like this before in the car. Any ideas on what to do? I asked them to test drive another G70 and see if they feel that too, I dont know if I'm being weird.

Thanks

What kind of accelerating? Youve done the same exact type of accelerating before and after the alignment and it feels different?

It would be normal for our RWD cars to lose a bit of traction during initial hard acceleration feeling like the ass end of the car moves around a bit before the LSD figures things out, you hook up and go.

As my tires have aged, it happens more and more easily which is another note to consider.

What you are describing is one of the reasons I bought this car with the 3.3. The 2.0t will make this go away.

How hard do you accelerate and what tires are on the car?

Very light accelerating. Just basic, comfort mode accelerating. Low speeds even, like 0-30 accelerate and let go. I figured it could be a tire thing and asked them if I should get new tires and they said "tires are fine"

This does not sound normal

Oil/grease on tires?

First question I would ask is how far is the alignment off and why? Did something get bent or installed incorrect from the factory?

My question too. Unless really high mileage or you hit something, would not expect a 2019 car to need alignment. Did they only adjust front end, or a 4 wheel alignment? Did they provide a printout of the settings after aligning? Alignments have a tolerance so would be interesting if the settings are nominal or more toward one end of the other of allowances?

Depending on km a 2019 is overdue for an alignment after 2 plus years imo. I would expect it to be out.

any update?

I wonder if the issue has something to do with one of the steel belt in the tyre went...unusual but that had happened to my friend some time ago.

I have read about some suggested alignment settings for our cars. See attached.

Sounds like the Steering Angle Sensor wasn't recalibrated properly after the alignment.
