2022 Toyota Redundant Sienna Fuel System Problems

Your 2022 Toyota Sienna Hybrid developed two serious issues shortly after purchase. First, the fuel line was rubbing against the rear passenger tire, causing a burning smell in the cabin—this was repaired by the dealer. Second, a "check battery" warning light illuminated and completely blacked out your instrument cluster, and the dealer diagnosed that the hybrid batteries were overheating, which they could not fix. The dealer could not reset the warning light, and Toyota was not informed of the battery overheating issue. Fixing this will likely require replacing or servicing the hybrid battery pack and repairing the instrument cluster warning system.

Your cruise control may continue accelerating after you release the button, which happened twice during a single trip. This behavior feels unsafe and differs from other vehicles you've driven. The issue may involve the cruise control system or its interaction with the forward collision avoidance system needing diagnostic review and potential recalibration or software update.
