2022 Toyota Redundant Sienna

The contact owns a 2022 Toyota Sienna. The contact stated that while driving approximately 35 MPH, the sunroof fractured without impact. The contact called the local dealer and was informed that the sunroof glass needed to be replaced. The vehicle was being repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 10,000.

When breaking at a stop sign or light, the vehicle occasionally feels like it surges forward and I'm accelerating instead of breaking. This causes me to push harder on the brakes, which then seem to mechanically engage and then stop the van. I've had the van for a year now and it happens a few times a month, especially if I breaking on an uphill incline.

While driving approximately 25 mph my dash lit up with the cross traffic sensor is unavailable and my blind spot monitor is unavailable. I got out and cleaned off my sensors on the outside of my vehicle all around the vehicle front and back and the warning has stayed on. It was not raining or snowing and I was on dry pavement at the time. My vehicle was not hit nor did I hit anything. There is no damage what so ever to the sensors or anywhere on my vehicle.

My issue is not with my Sienna but an appeal to the DOT to do some regulation or oversight of all the bright head lights on vehicles that are now so bright and many colors that is is dangerous at night for some people with eyesight problems to judge distances of oncoming vehicles. In a mix of vehicles some will have awesomely bright lights and some dim lights that make it just impossible to gauge what is what and some of these vehicles have huge light bars too, some of the large pick up trucks with these lights when behind me are so bright I can't see behind me, some vehicles have red and blue lights facing forward that first responder vehicles normally use. The DOT has to get on top of this wild west on our highways of headlights that are harming other drivers. Even the headlights on my Sienna HV with the adaptive feature are blinding to other oncoming drivers.

Question 1 Auto Headlight continues to malfunction and it has been inspected 3 times by Randy Wise Toyota (Grand Blanc, MI). Yes, it is available for inspection (video & list of incidents provided to Randy Wise Toyota - as requested by Tech/[XXX] but no action taken). Question 2 High Beams have come on when oncoming vehicle is between 300 to 500 feet - potentially temporarily blinding the person in the oncoming car and causing an accident. The High Beams also have come on when following vehicles within 300 to 500 feet, also in the City (with city lighting) the high beams were on with a City Bus approaching 1 block away. We have had numerous cars flashing their bright lights at us as our high beams do not dim to low beams appropriately potentially temporarily blinding us and creating an accident. We also are concerned about a potential road rage incident due to others thinking we are intentionally turning on our high beams. Question 3 No the dealership Service Director [XXX] took our vehicle home (23 miles each direction - during the day time) but only test drove the vehicle for 6 miles to try to duplicate the issue. When asked how many vehicles he passed, was told he was not available (out of town) we asked for a phone call to discuss this - but never received a call. Tech/[XXX] stated that we needed to provide video documentation and to keep a list of when the issue happens and details - which was provided but since there was no "CODE" they determined there was no problem. Question 4 Vehicle has been inspected by Randy Wise Toyota 3 times. Question 5 No warnings prior to failure. First appears immediately after purchase. Add'l Info: Video provided to dealership shows us following a vehicle (never loosing site of their tail lights) when an oncoming vehicle approached and when the oncoming vehicle was approx. 500 Ft. in front of us our bright lights turned on and remained on until that oncoming vehicle was approx. 300 Ft. from us.

I have had this issue ever since i got the hybrid sienna minivan. When at speed 45-65mph and slowing down (for example approaching an intersection), when the driver presses the brake the vehicle initially slows down using the hybrid regen system and at some point switches to using the mechanical brake. I hold down the brake at the same firm pressure but when the vehicle switches from regen to mechanical brake, the vehicle jerks forward as it starts accelerating briefly before the mechanical brake engages. this causes a panic in the driver because vehicle is not behaving how the driver wants. in my experience i have had to slam the brakes even harder. There is a bulletin by Toyota to fix this but my dealer said that did not apply to my vehicle. I have had issues hydroplaning / skidding when making a turn on wet pavement which i think might be due to the acceleration / jerk forward while braking during a turn. this happened to me again on 9/11, i crashed into a concrete base of a light post in a parking light at 5-10mph. the forward collision warning did not trigger and airbags deployed.

It happens more often when the interior of the car is super Hot and AC is in Max output and city driving speed around 35mph. When slightly braking for a longer time in Regenerative brakes mode, the brakes will let up. Not completely but it's as if my foot let up on the brake pedal when it didn't. It caused the vehicle to suddenly speeding up, even though my foot hadn't changed pressure on the brakes. increase the risk of not being able to stop the vehicle at low speed and cause rear-end accidents. I am thinking that it may be caused by a software problem when the battery can't take all the charge of Regenerative braking while the AC is in Max output and the computer lowers the power of Regenerative braking which causes the "speeding up" effect. It has been happened more than 10 times in summer time.  it will not happen when the car is cooler and AC is not in Max output.   100% sure that is related to the "Regenerative braking " . no problem for the hydraulic brake.

A tire and wheel came off of my 2022 Toyota Sienna while driving over a mountain pass. I was going downhill and around a curve, heard and felt some clunking, then watched my tire bounce across the two lane highway and over the steep dropoff. This was a potentially fatal occurrence, for so many reasons. This malfunction put the oncoming traffic and the drivers behind me at risk for collision, or worse. There was no warning lamp on, my tire pressure sensors read steady, and no other system lit up before or during this occurrence. The dealer can not find a reason as to why this happened within a year of owning it.
