Toyota Sienna

"Van stopped working after backing out of a of a parking space at Walmart. Van blocked parking lot traffic for 1 hour while waiting for AAA. AAA jump started the van, and Toyota replaced the battery the same day. This is the second time within 2 years the battery died and prevented thr van from starting. The 12v starter battery is too small. I learned from forums that you cannot leave van on ACC mode, as the battery drains too fast and doesnt get back to full charge. Some on the forums have gone for larger batteries; I will be looking for a larger battery that fits in that small space (or different chemical composition ) when this battery dies again. For $50K van, I wish Toyota put in more robust 12v starter batteries."

"The problem began shortly after taking delivery and has continued the entire life of the vehicle. Multiple toyota dealer service departments have failed to offer any resolution. Car would not start on multiple attempts and finally would start or require a boost. Vehicle was even towed to dealership and they could not find anything wrong."

"After replacing the battery we bought on Amazon, we often had to re-seat it have it work. The problem fixed itself after we bought a much more expensive battery from Toyota."

"The drivers seat has started tearing at the seam . It started about 32 months. I mistakenly did not take it to the dealer til 38 months. Then I was told the seat covers for it are on back order. Sounds like a systemic issue."

"The seats back tilt kept breaking for both middle row seats. The issue was the lever would stop working. After 4-5 attempts by the dealer to fix it, an escalation to Toyota helped to fix it."

"Twice over the past three years the middle row seat wouldn't move backwards and forward and/or flip to fold for rear passenger exit."

"The toe sensor that opens the sliding door doesn't work consistently. So, we don't use that feature."

"Rear hydraulic arms for tail gate went bad, costing $2000 to fix. Climate system is still problematic, in that the ducts are too small and it cannot circulate enough air through the vehicle. Too hot in the summer and too cold in the winter."

"The liftgate is a nightmare. Im unsure whether this is a mechanical problem or a sensor problem. The liftgate will neither open nor close without having to manually force it. It opens or closes partially the stops. You can push any of the three buttons (key fob, console, or tailgate) with the same results."
