Example complaints

“This was not an accident, it is, in my opinion, a possible safety problem with the vehicle - turbo lag; throttle lag; transmission lag. I almost had two accidents due to the lag problems, and have attached a more detailed analysis for your review. Turbo lag: this is the time it takes for the car to go from its naturally aspirated power to the full power of the car at full boost/ peak boost is reached relatively low in the reverse range, but it is not instantaneous power like a naturally aspirated engine. Throttle lag: the drive by wire system has a bit of lag. …”
