Bought car brand new less than a year ago. It still has less than 2K miles! Car is driven very little /on weekends. I stumbled upon this unexpected throttle response / TPS / driveability issue suddenly when it surfaced just after the initial 1K break in period during a moderate 0-60 run. The engine briefly cut out completely and bucked violently. Likely an electronic/ drive by wire issue - Acceleration and turbo response feels vague and unpredictable - similar to a lean fuel symptom or clogged air filter. Very unsettling for a brand new car! Oil dipstick shows at halfway mark after 1800 miles. Still using break-in oil. Initial oil service due in 1 week per dash notice. There is a noticeable smell of coolant on occasion. Going back to the dealer for its first service, a full checkup and for a damn good explanation...
