Car stalls when accelerating from a stop. happens on highway stop and go and when entering a junction after a stop sign. after the stall the car jerks as it suddenly lacks torque and goes to a lower gear. toyota technician said that traction control shuts off fuel. this is dangerous since it leaves you stalled after going into a junction. they issued a tsb 0197-17 that didn't solve the problem and they claim that there is no problem and that it is a driving style issue.
Car smelled of gas from the time i bought it (new) after it was started and it was driven for a few miles. sitting overnight, the smell would dissipate, but the same thing happened each day -- strong gas smell after a few miles of driving . colder weather, the smell was more pronounced. dealer didn't see any dripping gas, so sent me home twice without repairs being done. after they kept it overnight, they smelled the smell in the morning and only then decided to call toyota who said there has been a few problems with injector seals. it was repaired and is fine now. my daughter's friend had the same 2017 sienna and it caught fire on the highway and exploded --- my guess is that there is a very serious issue here that needs to be addressed.
