Rattling noise on passenger front side for a few months when going over bumps. Then one day, I cold started the car and heard some rumbling, and it continued so I turned off the engine, and the noise came to slow stop. Started up again the next day, heard the rumbling during start, and drove directly to the shop. I was told the front mount has collapsed onto the bracket, and the side mount needs to be replaced too. Came close to $600 for both front and side mounts.
Acura TL's are nice cars. I have a front motor mount brak. How i found out that it was broke, one day just looking for a new car to replace the Acura. My sales guy test drove it and it ran excellent, but he went to open the engine he showed me. The engine actually lifted up when he put it in gear. Taken to mechanics diagnosis and price quotes. $150.00 dollars for the part. But the labor is gonna get me. Havent gotten it fixed yet.
I had the front engine mount replaced (when putting car into reverse I was getting heavy thump as transmission engaged).
About a year and a half I was told it was shot again, along with the passenger side mount. Mechanic said the side mounts should have been replaced earlier, that's why the front mount went out so early.
Now I'm getting same symptoms again when engaging reverse.
