SERVICE BRAKES
When I am rolling to a stop, or lightly pressing in the brakes, the car will occasionally jolt forward and I have to slam on the brakes. It is not every time but has happened many times since buying the car new. I brought it into the dealership and they could not replicate it, but it makes me so scared to drive. This could result in an accident or the hitting of a pedestrian. No warning lights.

LATCHES/LOCKS/LINKAGES:DOORS:LATCH
The slide door latch stopped working. The sliding door doesn't latch properly and I have to manually close the door and lock it to know it's secure. If it's not locked a slight push will cause it to pop open. My mechanic said there is a recall associated with the replacement part. I can't find the recall. However, I did find a related TSB (TSB-0244-17).

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
The (PCS) Precollision System has been already set to LOW sensitivity, but every once in awhile when pulling in to oncoming traffic the vehicle would think there's still a car and just stalls for a few seconds (nonresponsive to acceleration pedal) leading to a dangerous occurrence where I could be hit by a vehicle because I've basically stopped in an active intersection. My vehicle is clean, so no dirt blocking the sensors, and I also own a 5th gen RAV4 without this issue.

UNKNOWN OR OTHER
The sunroof spontaneously exploded while in a closed position, not in use in any way, while driving in the rain on the highway. While driving at highway speed, a sudden “shotgun blast sound” occurred. The interior cover was closed. Wind noise became immediately apparent. Upon stopping to inspect, the exterior sunroof glass had shattered with the appearance it blew out from the inside, as the middle section was protruding upward. The sunroof has been used very minimally since purchasing the vehicle right at a year ago. There have been no issues with the sunroof. The vehicle is going to the dealership body shop in the next few days.

The is no positive lock to ensure the third-row seat is secured in the stowed position. In the event of a head on collision the seat may fly out and forward either killing or injuring the passengers.

SERVICE BRAKES
The brakes on my '23' Hybrid Toyota Sienna seem to have a sudden acceleration when braking at times. Typically, it happens when braking going down a hill or around a curve (at slower speeds) and sometimes when trying to come to a full stop. This has caused me to almost rear-end other vehicles on several occasions and has also caused me to go slightly beyond the stop sign, putting the nose of my car in the street. It is not reproducible at the dealership. It has happened since I drove it off the lot in July of 2023 and happens randomly and without warning. This is scary when you seem to be braking in plenty of time to keep safe distances and then you suddenly get propelled forward! It happens weekly and has happened weekly since purchase. In speaking with other owners, this sounds like a common issue.

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I have had this car for 7 years. Started having issues a year ago and despite bringing it to Toyota 2x, they cannot tell me what the issue is. I will be driving on a regular flat paved road when the car will suddenly brake and pull me towards the side of the road. I get the ABS code sometimes and also the slip indicator light. I've explained this each x I've brought it in and they have told me it's due to me "driving too fast" or "accidentally having my foot on the brake." LOL I am a typical soccer mom and drive conservatively and don't brake when I don't have to. It will do it on curving roads as well as straight roads. When this happens, it is terrifying! I have gone to different mechanics as well and no one can determine this issue. I've replaced the ABS sensors on this and am still having this issue. I don't know what else to do, as this is unsafe and unsafe to the extent that I no longer allow my 17 year old to drive it. Please help!!!!!!!!

SEATS, VISIBILITY:REARVIEW MIRRORS/DEVICES:EXTERIOR
The drivers mirror shakes every bump you hit so everything looks blury going above 30mph. This is a huge safety concern as you can't see cars clearly in the mirror. One of the second row seats also shakes considerably. I have brought it to the dealer multiple times and they will not fix it.

SEAT BELTS, UNKNOWN OR OTHER, AIR BAGS
Water intrusion from front sunroof when vehicle is parked at a 5% grade with the nose downward. Multiple vehicles exhibit this issue. Toyota is not creating any TSB and will mot even remedy it even if we have an extended warranty. Here is a link to the discussion thread: [XXX] I have not posted on this thread but I have the exact same issue for years. Toyota dealerships want me to first pay $1000 in labor to pull down the headliner and test. Then ask the warranty to cover the assembly, if they don't cover it... then I am on the hook for the work. The missing seam sealer is a common issue that will not manifest inside the 3yr / 36k mile warranty. My issue started around 2020 that I noticed and every dealership would not help me other than place a large burden on me. This can impact the electrical and the airbag curtains. The issue needs to have a seal sealer added to the sunroof assembly as the fix. As a family vehicle, this is a dangerous issue for multiple occupants in a single 7 or 8 person hauler minivan. Please ask Toyota remedy this issue that has been going on for over a decade. Please ask them to stop forcing customers to have sunroofs and panoroofs... when they can't build it correctly.
