Exterior Lighting problem #1

The wiring harness connector for both lights has had water accumulate in the connector which causes the rear tail lights to fail. Both of my tail lights have failed, and the cause was corrosion inside the wiring harness connector. I had to replace the wiring harness and connectors on both sides, driver, and passenger and I had to pay out-of-pocket. The dealer said that this problem is common on 22 Sienna's and I have seen other 22 Sienna's with out their driver and passenger rear running lights burnt out.

Exterior Lighting problem #2

Our 2022 Toyota Sienna would not start after arriving at a doctor’s appointment. Contacted active Toyotacare for towing - no one showed up. Called a friend to jump start van; consulted the owners’ manual and performed jump. Van started but could only be driven about 100 yds in parking lot. Van stopped; multiple error codes showed up when trying to jump start again. Toyotacare didn’t call again or show up so we ended up paying for tow service to the dealership - haley Toyota of richmond. Dealership checked vehicle; concluded the battery had an internal weld problem but that the jump start was not performed properly even though the manual was followed. There are no jump start instructions in the engine compartment. We were given a tech bulletin instruction sheet with more accurate information. We were advised the engine control unit was burned out, causing all the error codes and would not be covered under warranty because “we” did not perform the jump start correctly. The cost of repair is almost $1100. 00 but the battery, which started all the issues, is covered under warranty. The tech instruction sheet indicates to me that Toyota was aware of the inadequate jump start instructions and failed to inform customers of the possible issues. The tech instruction sheet we were given is dated April 6, 2022 - one month before we purchased the vehicle. The sheet lists all Toyota hybrid models as affected.

Exterior Lighting problem #3

Problems with the seals in the headlight lamp, water entered it and it was damaged.

Exterior Lighting problem #4

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/mychal urssing 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 (brent edwards) 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/mychal urssing 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.
