i'll blame the service center. i recommend go find a better one.

i've found one in JB. the mechanic (or engineer rather) would do everything to solve even my slightest issue with the car. my exora's steering had a slight but noticeable "whrrr" while turning. he checked it, agreed there's the sound, and start diagnosing the problem.

finally he decided the steering mechanism (cant remember which part) was wearing out, and ordered a replacement. he then told me to come back 5 days later. i came back, got it replaced, and came back happy customer.

but the center's queue is really long. everybody already know their tiptop service. now everybody wanna go there.

moral of the story is, it boils down to the person who meets the customer that reflects on the performance of the company.
