Have Subaru Questions? Ask a Subaru Mechanic and Get Answers ASAP
Hello. My name is ***** ***** I will be assisting you today. What condition are your tires? Do you have tire chains on your vehicle? Sounds like the transition from surface to surface is causing this. Have you had the ball joints checked? I know its a new vehicle, but I also know that things happen.
I would also have them run diagnostic for traction control, vehicle stability control, and wheel sensors. These may be causing slight issues also. Do you have any warning lights on?
I wouldn't suspect that turning off the traction would change anything, because I already suspect it not to be working and the srs is air bag and restraint control
Is the shifting coming from the front or back? Can you tell?
I understand. I'm leaning more towards the wheel sensors compensating for the momentary loss of ground/control of a spinning tire, if its not because of the tires. The quick pulsation of the brake would cause this jerk/skid.
The only thing the you can really check on your own is the fuses. You can look for shifted belts in the tire, you can jack up the vehicle, and inspect the ball joints tie rod arms, look for anything shifted or able to be shifted by manual force. Remember to use jack stands.
If your brakes are grabbing then that could be a very real possibility. The wheels should rotate easily, but not freely. The bumps that you are feeling, could be excessive run out of a rotor, or it could be a bad tire. Both will have you feeling a pulsation in the pedal. If the bad tire is in the front, then you may notice the steering wheel rocking from side to side.
If you have found this information helpful, a positive rating would be greatly appreciated. Thank you.
