Lenore i don't think it is fair to make such judgmental comments.
In 90% of issues they step up to the plate which is more than any other car maker.
There is always 3 sides to a story and who are we to assume we are getting the full picture in this thread? Such as what the mileage is ,did i miss it? Is the car frequently started and turned off such as moving it on a driveway or idled for long period of times such as in NYC traffic. Another issue could be it is never pushed hard enough to break any carbon down but make it build up.
Always 3 sides ,you can't assume you know them all.
