When I am driving my car it gives a slight vibration only at 20 - 23 mph, Afterwards, the driving conditions are normal. I've had it at Toyota dealership three times now. They fixed a caliper and rotors 1st time. 2nd time they fixed axles. 3rd time, they said it's normal. Is this normal? Can it be fixed?
My car has 34890 miles.
My car has an automatic transmission.
The vibration is not normal and probably reflects an imbalance in a rotating engine or transmission component. Once engine speed and gear, at the time of the vibration, is known, that might help to narrow the diagnostic and in a really tough case it might be possible to apply a frequency domain (electronic) analyzer that can match the vibration frequency with what are referred to as "most likely components". In any event, to answer your question, of course the vibration is not normal but it will require a diagnostic to figure out the source and once figured out the required repair will be self-evident. The bottom line is you should request a vehicle vibration diagnostic. If you have additional concerns or a follow-up on this, don’t hesitate to re-contact YourMechanic.
