I would like to make formal complaint in regards to a manufacture defect. I purchased my Toyota Sienna XSE brand new in August of 2021 at Cerritos Toyota in California. On December 24th at approximately 1:30 p.m. on Christmas eve, after filling up gas at Sam's club in Fountain Valley, CA. I pull out on to the street heading northbound on Warner approaching intersection as I come to complete stop on red. All of a sudden, my Sienna completely shut itself off and the engine light came on. I put it back on park and restart the car. As I attempt to accelerate forward. The car jerk and the brake didn't work and the engine light came on. Fortunately, I was able to make a U turn and pull into a gas station near by ( Shell) and I thank the lord almighty there was no car right behind me. I could of gotten rear ended. It was the most terrifying moment of my life. My wife and I was in the car at the time of the incident. We waited patiently over an hour for Triple AAA to have it tow the nearest dealership next to my house in Long Beach, CA. My 2021 Toyota Sienna currently has 52,023 miles and sitting at the dealership to be repair at Long Beach West Coast Toyota. I have contacted Toyota of this incident and they refused to fully covered repair instead they offered me 700 payment assistant the rest would come out of my pockets. I believed the car should be part of the campaign recall and nothing should come out my expense. I would like you you guys to investigate the incident and look into this matter as soon as possible because there thousands like my mind that could there have the same issue but was not part the campaign recall. A bulletin was published on April 13, 2022 affecting 2021 -2022 Toyota Sienna. Production Period March 3rd, 2020 through April 7th 2022. Manufacture's Campaign Number: Toyota: 22TB03

The rear climate control unit has fallen out of the headliner several times. The climate control unit then dangles from the headliner, obscuring the vision through the rear view mirror and poses a potential safety risk as it could hit a passenger in the event of an accident or abrupt stop.

I currently have 35,000 miles on my 2021 Toyota Sienna. Ever since I passed 30,000 miles I’ve noticed a difference in the braking. When I start to brake it feels normal and then all of a sudden it feels as if there’s no braking and the van surges forward for a fraction of a second before the brakes engage again. I’ve experienced this on highway exit ramps, braking before turning into parking lots and while coming to a stop at traffic lights. It usually happens around 40 mph & 20 mph. It does not happen every time I brake but it happens multiple times every day. I took it to my Toyota dealer but they told me they could not replicate the brake malfunction. There are a number of other Sienna owners who have documented their same experiences with surging brakes on an online Toyota Sienna owners forum. I have not had an accident yet but I find this brake surge very concerning.
