Just wanted to post this in case anyone else is having similar issues: Just bought my PT 06' last week, noticed a shudder when accelerating between 40 - 50 kph - turns out the right hand engine mount (underneath at the front of the engine) is completely stuffed , the other engine mounts need replacing as well though are fortunately still in one piece. Needless to say I'm not too happy with the car dealer and am pushing to have them replaced at their cost as it's unsafe. So, any shudders?? Check your engine mounts! No shudder? Check then anyway - apparently they're rubbish.
