I have recently purchased a new MQ Mitsubishi Triton utility from Agostino Mitsubishi dealer in Elizabeth SA. During the initial test drive, I asked the salesman about a vibration on acceleration from stationary and I was told it was due to the demo car having high tyre pressure and that we were on a rough surface. I completed the test drive and ordered the new car, however, the vibration in the new car was evident immediately with standard tyre pressure and on smooth surfaces. Advise from the service manager was that this is a known fault and Mitsubishi was working on a "fix". I contacted Mitsubishi Motors Australia Limited and I have received the following email on 22 Apr 16: Dear Mr T Subject: Mitsubishi Triton Receipt of your complaint regarding the above-mentioned vehicle is acknowledged. Naturally, we regret to read of your dissatisfaction and your comments have been noted and are respected. Please be advised customer's concerns regarding this particular characteristic of the MQ Triton have been escalated to Mitsubishi Motors Corporation (MMC) in Japan and after their investigation, have advised that this is normal operation of this model vehicle. The cause of the vibration in the MQ Triton is the result of suspension production improvements over the previous MN model Triton. The intended design of the suspension was to be stiffer to give better load carrying capability while towing and carrying heavy loads . This vibration is not detrimental to the vehicle. I am annoyed that this information was not provided to me prior to purchase. I drive this vehicle to work and not for towing etc. I have since been to another Agostino dealership at Nailsworth SA to test another vehicle and was advised by that salesman that there are no known problems with this model. When I demonstrated this fault during the test drive, he asked would that problem stop me from buying the car- I answered Yes. What are my options to get a refund on this vehicle under Australian Consumer Law?
