Hi. My 2012 idtec with 160k miles noticeably shakes under hard braking or acceleration. Not a problem with speed, wheels and brakes are fine. Had mechanic look short while ago with no problems identified. Years ago I took my 1999 Accord to local garage with similar problem and mileage, they knew straight away that it was an engine mount. Has anyone had similar, or can you suggest what to start replacing first? Thankyou.
