I ve got a Toyota yaris 2015 1.33 hatchback model. There is a rattling noise when I just start to move my car in 1st or reverse gear. There is no rattling noise when the car is idle, but only when I start to pull away. It stops after I attain a certain speed like above 10 or 15 mph. Any Ideas? . And it happens only after calm acceleration
According to my observations,
Rapid vehicle acceleration in just after start or any other time, no noise
Idling just after start or any other time, no noise
Idling and throttling in neutral or parking position, no noise
higher speeds and rpm, no noise
noise comes only after calm acceleration just after start and for few seconds and after a few hundred yards, it goes away.
I would highly appreciate any help. This has been going on for quite some time now. I did a full service but the mechanics were unable to find a solution.
