The Toyota Cross XR problems

I bought new Toyota Cross 1.8 XR. The milage currently stands on 13 800+. I had numerous problems with the vehicle. At first the battery ran flat a couple of times. AA had to come out to assist. It happens quite a lot. Toyota East Rand informed me that it is because I don't drive a lot. A drive many vehicles from luxury to standard vehicles an it is the first time that I experienced this. I had to fit a bigger battery in my vehicle. So beware this vehicle is not for drivers who do not drive a lot!! The latest problem is that there is a vibrations around 2000 refs. After nearly a week the problem could not be detected. The vehicle is still in the workshop and await a Master mechanic which will return to work on Monday! I have many obligations which could not be attended to. I requested a courtesy vehicle from the branch which was not approved. At this stage I am desperate. It is not my fault that a fairly new Toyota Cross is not up to expectations. I had loss by holiday booking to KZN twice. So I had to pay penalties.
