Yay, Yet Another Vehicle Hijacking By Maker Lazyness
This situation sucks. Now, when buying a car, one is going to have to go through a number of checks to ensure that the car cannot be easily broken into via passersby smartphone, in addition to all the other stuff to evaluate.
And the problem is not that Mitsubishi did not think of implementing security - they established a procedure and implemented it - probably after testing it. The problem is, nobody made a quality check - or even a sanity check - with either security engineers or a simple street thug (the latter may be a bit difficult to locate for a car maker, I agree). So what they designed is trivial to crack and nobody is safe.
I do not want to have to become an engineer to have a secure car. In any case, Mitsubishi is off my buy list until they get this sorted out.
