what JD power doesnt tell you is that some people, when they buy a certain brand, are able to tolerate more and find less reason to complain. it doesnt have a psychological column...for example buyer X buys a toyota, thinking super reliable brand. any tiny problem and its back to the dealership or complain. buyer Z buys an infiniti, reliable yes but not following the same long developed reputation as toyota, a problem very small may be overlooked. its rather difficult to explain.
i agree that infiniti has developed a stronger reputation along with nissan, but i pretty much despise JD power ratings.. i filled it out myself on my 2002 Si, but only for the money they gave me. its somewhat, not entirely, impossible to judge the future by past performances in the auto industry. how a 2002 civic performed, could be entirely different following 3 years of development and evolution
