Hi people, just joined the forum as I've bought a 57 plate c max and have a technical issue. Basically it seems to drive fine up to around 70 but sometimes a bit slower then it starts to judder. It's not horrendous but quite annoying. It only really happens when accelerating and if I back off and maintain a constant speed it goes away. I can cruise at 80 no probs and nothing when braking. Seems a bit beyond my mechanical knowledge which is why I'm asking you guys for help. I hope you can as I already wasted £1000 on a bmw I bought a couple of months ago which is now dead, and can't afford any more problems! I thought maybe bushes but I'd expect some judder when braking so maybe not. I will take it to my mechanic later in the week but would be nice to know if there are any common problems to look for. Thanks, Dan. (I think I can rule out tracking as that was done along with 2 front tyres yesterday, as one had a puncture and the steering wheel was turned to the left when going straight). They did say they'd like to see it again in about a week incase it goes out again which I thought was a bit weird and made me wonder if they found any kind of problem.
