2020 Toyota Sienna Engine Problems

Your engine stalled while idling at a red light in traffic with no warning lights, but restarted normally. Later that same day, the engine stumbled and hesitated for a few minutes after starting. The problem happened again on a different occasion when accelerating from a stop—the engine briefly died, the master warning light came on, all power cut out, but it recovered when you gave it more throttle. The dealer found no issues when they checked it after the first incident.
