Why does my ix35 engine vibrate at 40 mph in fifhh gear when you accelerate
Hi John,
You've not told us the year or engine so we can't look into it in too much depth, I'm afraid. That could be as simple as a worn engine mount, but it could be something more serious within the engine as well. Best to get it along to a good mechanic to look at as soon as you can.

Ask us anything motoring related and please provide as much information as possible so we can give you the most accurate advice.
