I've had my LGT for 3 weeks now with about 1100 miles on it and have noticed a buck/studder/bog at low RPMs in 1st and 2nd. This is most prevalent in stop and go traffic and when coming to stopsigns/lights/yields, and starting up after the appropriate actions. It does not happen all the time, but enough to make me aware of it.
I travel in the car at about 3.5 RPMS and shift in the high 3s to keep it out of the range. I have not experienced any problems in high gears.
I run Shell 93 V-Power fuel and thought it was my driving, but after talking at the dealer today, I am convinced my driving is not the problem.
I will go back tomorrow to the service rep, and document the problem.
This is the first turboed car that I have owned, first Subie, and I can tell you it won't be my last, but this problem is getting annoying. Hope its a simple fix.
