The records describe a problem worth checking before purchase.

“The contact owns a 2020 Toyota Sienna. The contact stated that while his wife was driving at an undisclosed speed, the pre collision, lane assist, and air bag warning lights illuminated on the instrument panel. The vehicle was taken to a dealer and a fuse in the ECU (Electronic Control Unit) was replaced; however, the contact stated that approximately 10 days later, the failure recurred. The vehicle was taken back to the dealer where the vehicle remained for almost two weeks. The contact was informed that the wiring harness needed to be replaced; however, the wiring harness was on backorder. The manufacturer was notified of the failure, but no additional assistance was provided. The contact was provided a case number. The vehicle was not repaired. The failure mileage was approximately 60,000.”

“Spontaneous and random: Blinkers come on, radio volume goes up or down when turning the other way, CarPlay USB shuts off and on, hiccups when accelerating (when ECO kicks on/in)…everything points to an electrical/computer issue. Purchased used from a dealership and noticed these issues after the 3-day return window.”

“Speakers make an ear piercing loud noise that lasts about a second. If this sound were to occur during travel, could cause distraction leading to harm, or with young kids in the car, possibly damage their ears. This problem has been random and not experienced by a dealership. No warning messages or symptoms to the problem. Problem first appeared 6 months ago.”
