Hi all, hopefully someone has experienced this problem and got a solution.The Speedo on a 2015 model is very inaccurate. Once the car has warmed up with the car doing approx. 40 mph the speedo will be showing 100mph. Then when the car is stopped and stationary the speedo will still be showing 40mph.On other occasions the speedo will under read with the car say doing approx 40mph or more the speedo will be hovering around the 20mph mark.So obviously something to sort out. Thought maybe the speed sensor or instrument cluster.Be interested to hear from anyone who has experienced a similar issue. Thanks in advance for any advice/help .Regards Gabriel.
