I have had mine for only three days and it is irritating the life out of me. I noticed it straight away as I drove away from the dealers. It's as if something was loose in the transmission or maybe the exhaust system. Did you ever get a solution?fergie said:Has anyone noticed a vibration noise when accelerating through the gears on their Cactus. I have had mine for 5 months and I love it but this noise is starting to get to me, any comments or suggestions welcome.
