I have only one gripe about my Speed6:
It's stuck at the dealership for at least 2.5 weeks! and I'm stuck with a tiny Hyundai as a loaner. (I'm thinking it's actually going to be longer than that too, since I don't believe their diagnosis)
Here's the background, sorry for the length:
I took my 2 month old, 4k mile, '07 Speed6 GT into the dealership last Monday (9 days ago) to have them figure out why it's been difficult to start in the morning and has a severe, although intermittent, hesitation before it warms up. I started noticing it about three days before and it had eventually declined to the point that it would start, but barely idle, then die about 10 seconds later. After three or four restarts it would finally idle right, but any throttle input would cause it to bog and die, and I'm not talking about drag launches here, I was just trying to back out of my driveway, and it's not a lack of manual transmission skills. It felt just like it had an old carburetor and was trying to flood every time I hit the gas pedal, but as soon as it warmed up it drove just like the day I bought it.
They first told me there were some computer updates, and all would be well the next day.
(When I heard that, I thought to myself "that's funny, I've been reading quite a bit about this car since I started looking at them, and I wasn't aware of an ECU reflash for the 2007's, but whatever, they're the experts, right?")
The next day they had "reflashed the computer" but they still couldn't keep it running. (Yeah, big surprise...)
Eventually towards the end of last week they decided that it was the high pressure fuel pump. However, there isn't a single one available in the U.S. so it has to come from Japan. Apparently Japan is on vacation all this week, so it's going to take until the middle of next week before they even get the fuel pump! (If they're right on their estimate, that will make my car stuck at the dealership for a total of 17 consecutive days, before they can even get the part that might fix it.
To add to the confusion, it hasn't thrown a single check engine light this whole time.
So here are my questions, but I'm not sure if this is the best place to ask it:
Is there any history of this, or do I get to be the first?
AND
Isn't the high pressure fuel pump in these engines mechanically driven by one of the camshafts? How does that fail, only sometimes, when cold, but then work great when warm?
AND
Does it sound like the dealership has any clue what they're talking about?
I'm hardly a master mechanic, but I'm also not your average consumer. Automotive related stuff is my hobby and for three years in college I was pursuing a degree in automotive engineering. (I switched to Computer Science in my last year for a number of reasons, but that's an entirely different topic)
Thanks in advance for your thoughts.
