I have a Lexus GS300. Couple weeks ago I sent it to a Toyota dealer for maintenance. In addition to regular maintenance, they said the brake needs change and so I agreed.
This week I found something strange, after I park the car at garage, I hear some air squeezing sound, the sound is like air leaking from a balloon, but maybe a little bit lighter. I am not 100% positive, but I think the sound is from the tires. The sound lasts maybe half minute. The thing is I can hear it almost every day when I come home and park it at my garage at night. In the morning, I park the car at the parking lot, not sure if it is because the environment noise is loud, I do not hear it. I never notice this problem before on this car.
Do you think this is something worth a mechanic to check out? I do not notice any problem yet, but I am pretty dumb at car mechanics.
