We've got a 2016 LS 460 with 35K miles. We have been experiencing an intermittent engine power issue. Upon normal acceleration from a stopped position, the engine will suddenly 'bog' down and barely have enough power to move the car forward. This is highly concerning when pulling into traffic because you never know when the problem will arise. We had the car into Lexus for an extensive look into the issue and they could not find anything (nothing reported on the computer, nothing noted by the technician). Any ideas? Thank you.
