At my 120,000 service, the toyota dealer technician reported a leaking front differential. He said it would take 16 hours to repair. The technician also mentioned that he had 3 toyota cars currently in the shop for the same thing. This seems beyond coincidental. Clearly, toyota has a problem with leaking seals. The difficulty to fix this problem translated into a bill of $1,404.60 plus $31.79 for a rental car. The…

Four year old child shifted vehicle out of park into neutral causing it to roll down a hill and impact several trees (no injuries). After the incident, we have found that the vehicle can occasionally be easily shifted out of park with no key in the ignition and without…

I was driving my husband to work, when we pulled into his work, all of a sudden i had smoke coming from under my hood. We shut the vehicle off, i had oil everywhere. We couldn't tell where the leak was. I had the vehicle towed home and then to elk grove toyota. Well it turns out that the oil cooler line broke. This is a design flaw in 2007 to 2010 toyota sienna's. There are technicial service bulletins but no…

Transmission had been hesitating at times, but mechanic couldn't find any problems. At 60,400 miles, the transmission died completely and we were stranded far from home. This occurred on a well-maintained vehicle. Because it was over the 60 months/60,000 miles warranty, toyota offered no assistance. Between towing and replacing transmission, it cost us $5900. Even the mechanic was surprised by the failure at such…

On 11/12/15, the radiator body around the lower transmission oil line fitting on the radiator cracked, allowing the fitting to break away from the radiator. This caused almost all of the transmission oil to be pumped into the right side of the engine compartment. The vehicle was being driven in heavy rain on rain soaked roads at 55mph on secondary roads when smoke was observed. When the vehicle was stopped heavy…

Our sienna is a well maintained, low mileage (just over 66,000 miles) vehicle. As of august 30 of this year, the transmission planetary gears have totally failed, leaving the vehicle and us stranded over 100 miles from home. The estimate for a complete transmission rebuild from a reputable transmission specialty shop is $4500, which is much lower than the estimate of $6500 that our toyota dealer gave us to install a…

I was northbound on interstate 15 in utah and noticed smoke coming out from underneath my car. I pulled into a firestone service center where they diagnosed the issue to be a faulty oil cooler hose assembly on my 2007 toyota sienna mini-van. I contacted toyota dealer who said that the part had been upgraded from a rubber hose to a metal hose that would not burst like mine had. I was not informed of the option to…

Upon slowing down to turn a street corner the transmission slipped before it would go again. It seemed that it was between the slowing down and re-accelerating after the turn. This problem is well documented on google by many drivers. The dealers reprogram some computer and then declare it to be fixed when the same problem occurs again. Toyota refuses to fix the problem which costs one about $3,000 to actually fix…

The transmission problem first reared its ugly head when i was backing out of a parking spot one early morning in november 2011. It sounded as though i had run over something. After getting out of the van and looking around it appeared as though everything…

Engine/powertrain hesitates for 1-3 seconds when accelerating slowly, or accelerating quickly after slowing down such as when slowing down in an intersection, making a turn, or in slow traffic. Engine has piston slap for 3-5 minutes after a cold start in weather below 40 f. The slap becomes louder with colder temps. Shifting into gear with a cold engine can cause the vehicle to lurch due to high idle. Driver must…
