Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Your Lexus is doing the automotive version of a mood swing—hesitating, then taking off like it just remembered it’s late for work. This could be a dirty throttle body, a failing mass airflow (MAF) sensor, or even a fuel delivery issue. Since it happens more when driven a lot, heat could be affecting a sensor or fuel pump. Start with the basics: check for stored trouble codes, clean the throttle body, and inspect the MAF sensor. If it still acts up, a mechanic might need to check fuel pressure and scan live data to see what’s throwing a tantrum. If you need any further advice or want help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554.
