This is pretty bad. My new car, with 2,000 miles on it and which I've "owned" for 30 days, has been at the dealer for the past 10 days straight. They still don't know for sure what the problem is, or why it's happening. I've been told multiple "causes", only to be told later that was not the reason. They've changed the computer component which controls the engine, "reset" the engine and warning lights, adjusted the valves, tightened the valves, and are now trying to see if the head cover need to be replaced. I've called Acura "Customer Relations", to no avail. Seems awfully funny that you pay this much for a new car, only to find that they have to overhaul the engine. I expected more from Acura than this.
