2023 Toyota Sienna Hybrid

2 month after buying the car, in Jan i turned the car on and the windshield wipers didn't work. It was a snowy day and the salt and snow made it dangerous to drive. Before i had a chance to bring it to the dealer, after about 2 hours, the wipers started working. This happened again in April, i was driving on the highway and it was raining intermittently. . I was using the wipers, and suddenly they wouldn't turn on. I pulled into the first rest stop and forced the wipers up by hand and than it started working.

We had a "hybrid system malfunction" warning on the dashboard and the van slowed down to 20 mph on a climb. With the flow of traffic at 50mph on a two lane road and no shoulder to pull off, this cause a serious risk to us and other drivers. Stopping and starting the car several times did not cause the warning to go away and the owner's manual says to stop driving. There were no warning lights prior to this happening. The warning and the MIL came on at the same time as the van started slowing. The local dealer now has the van and are not able to exactly diagnose the problem. They are contacting the manufacturer. They said the warning is no longer on.

There is a problem with the lighting in the information dial. The handbook even says the gauges may be hard to read in daylight if any lights are on. The daylight driving lights are always on. This is even worst when headlights are on. Many states like Texas, New Mexico, Colorado, Utah, Nevada and California have roads where headlights are required at all hours. There is also much sunlight. The gauge is virtually impossible to read. This includes the tachometer, fuel gauges, engine alerts, low tire pressure, etc. I feel this can cause unsafe conditions by not being able to access the data or drivers having to lower their head trying to read the info. With todays LED technology why would they not put a usable lighting system on the gauges. It makes no sense at all. This was a design and manufacturing defect and should be corrected. It does have a brightness control switch but the above is while on maximum brightness setting.

The entertainment screen is completely blocking the rear view when in use which is very dangerous when backing out. Also, I can’t see ambulances, fire trucks, police, etc. are coming behind me to pull over. This is a very serious safety issues for driver. Toyota said that I need to close the screen when this happens but it’s more dangerous for the driver to turn around to close the screen while driving.

No system is failed in our sienna. Only safety problem we have is the rear view mirror completely block off when kid use the entertainment system. When I talk to the deanship, they told me they can't add any rear view camera due to the electrical harness problem. Not sure if anything can be done, please let me know what you guys think.
