2020 Toyota Sienna

My car was not shifting gears, and it would go into brief periods of erratic acceleration. I took it to the dealer service dept. The transmission went bad. It had metal pieces broken off inside it. The car is 3 years old and only has approximately 70,900 miles on it. It was dangerous to drive. It put me, my kids, and other drivers at risk due to the erratic shifting it would do while driving. The issues started slowly on 6/23/23. The check engine light was on by 6/24/23.

For a month prior, there were intermittent incidents of the van shuddering and the RPM needle jumping upon ignition. Sometimes the van would have a hard time accelerating before jerking and driving normally. No issues before this started in late July and no indication when/where would occur. •September 15: drove the van all day running errands. It drove normally. Filled up the gas tank (Gulf gas station), then continued errands. About a half hour later, while at a stop sign, a notification appeared that the “Traction Control System has been turned off” and the check engine light came on. Tried to move through the stop sign, but the van would barely go. Applied the gas, but no results. Able to turn onto a side street and had to have it towed to Toyota of Irving. The Service Advisor stated the issue was due due to bad gas and indicated the van needed to be flushed and the fuel injection system cleaned. Paid $725 for these repairs. •September 17: Started van in driveway. Shuddering and RPM needle jumping again. Drove normally. •September 21: Same as above. •September 25: Drove the van all day with no issues. Filled up with Valero Plus gas. As we pulled out of the gas station and sitting at the light, the Traction Control message and check engine light again appeared. The van would barely go to get us through the traffic light and into a nearby parking lot. Once we parked, the screen displayed the following message:"A malfunction in the electronic control of the engine, throttle, or automatic transmission has been detected." Had the vehicle towed to Toyota of Irving. The service advisor called 2 days later to say they cannot detect any issues.

The van has been periodically hesitating, rough idles, and when parked the rpm revs. On 9/13/22, the van was shaking, hesitating, and would not accelerate. It was undrivable and had to be towed. We took it to Toyota of Irving where they charged us $725 to flush the gas and clean the fuel injection system. Despite this, it is still hard idling and hesitating.
