As I was driving the van, I noticed a smell like burning rubber, although all gauges were normal and no check engine light was on. Since I was close to home, I pulled into the garage and noticed smoke coming from under the hood and a trail of oil on the drive way. Within a few minutes, there was a large puddle of oil under the vehicle as well. I had it towed to the mechanic and was told the oil cooler hose had broken. The mechanic said if I had driven it to the shop, I likely would have ruined the engine because the oil loss was so significant (out of 5 quarts, only .25 was remaining). The mechanic also said that toyota was aware of this issue but did not issue a recall, even though the replacement hoses are now steel and not rubber. This is a safety issue as the engine could have seized up while running (due to the quick loss of oil) causing potentially serious accident and injury.

Driving car in town for about 10 minutes. Stopped at friends house and noticed when I backed out a large oil puddle. Got out and looked under car to see undercarriage covered in oil from front of car to midway down car. Could not tell where it was coming from so I called tow truck to take to toyota dealership. They found small hole in oil cooler line was spraying oil out. It was half empty of all its oil in that short amount of time. The dealership told me it was going to cost me $360.00 to replace oil cooler lines. I was very lucky I had not driven very far or probably would have been catastrophic engine failure. After quick check on internet, this appears to be a common issue with oil supply lines in this and other model years. Also looks like there is a new all metal oil supply line and a warranty extension (ze2), neither of which I was made aware of by my dealership and was very difficult for me to find.

The front lower oil cooler pressure hose (toyota part no. 15767 31010) started spraying oil out while the van was being driven under normal operating conditions in a residential neighborhood with young children in the car. Had this occurred at a higher speed (on a highway), all the oil would have sprayed out and the engine would have seized. This could have caused an accident or the van could have caught on fire. This is a well known problem with this part that toyota has done almost nothing to fix or prevent. We were extremely fortunate to have discovered this problem immediately.

I am the second owner of the vehicle. I was driving on interstate 5 at 65 miles per hours from sacramento to los angeles. The time was 1600 on 13 april 2014. I did not notice any crack or noise from road debris damage while I am diving. The red low oil warning light on the dashboard did not turn on at the time when the incident happened. I was pulled over a rest stop to use restroom; I also walk around the vehicle to conduct a visual check and fluid check at the same time. I was discovered engine oil was all over the engine bay, undercarriage and the back lift door during the visual check. When I checked the engine oil, the dip stick showed no engine oil. Again, the red low oil warning light did not turn on which indicate low engine oil at that time even the engine had no engine oil. Vehicle was towed to toyota dealership and discovered an oil cooler hose which make out of rubber was ruptured. Even the oil cooler hose was replaced with a metal oil hose; the engine was damaged by operated without engine oil for a significant period. Prior to the trip, I purchased the all metal vvt-I hose from a local dealership, again no warning from the dealership. I used a local repair shop to replace the vvt-I hose locate at the passage side of the engine to an all metal pipe since I have knowledge on the rubber vvt-I hose have the same rupture issue. However, I have no knowledge on the t-sb-0201-11 which is the toyota technical service bulletin title oil cooler pipe seep. There is recall regarding shift lock solenoid and severe corrosion of the spare tire carrier cable on the 2007 sienna, however, there is no recall on possible rupture on vvt-I hose or oil cooler hose. If the recall was issued or at least warned by dealership, I will fix the oil cooler hose at the dealer or a local repair shop and avoid the engine damage which leaded to engine replacement.

June 12, 2012, odometer 45,000 miles, 2 hours from home, drivers side manual door would not close and latch shut. Called nashua, nh toyota dealership, told lots of problems with doors, need to make appointment, average repair over $1,000. Took to my regular mechanic and problem temporarily fixed for $244.80(latch assy seized up. Remove, lube, reinstall. If repair doesn't last, new part needed. Cost for part only, $570.23, plus labor). July 2013, odometer 65,000 miles, same door not latching again, door slides open during acceleration. Called toyota dealership in nashua, nh, told door not covered under "latch assembly extended warranty" because door is manual. Have made appointment with my regular mechanic again to see what can be done to fix problem. My vehicle has 2 sliding doors, drivers side is manual, passenger side is automatic. However, the manual door has a motor and latch assembly to pull the door in and latch it after it's been slid closed. This function is not working properly. The extended warranty I received from toyota in july 2012 states " this warranty extension is for your rear sliding door latch assemblies for a period of 9 years from the vehicles date of first use or 120,000 miles whichever comes first". There is no mention the door must be an automatic door. I believe toyota is trying to limit how many warranty fixes they do by giving customers incorrect information. I'm also beginning to have problems with the passenger side automatic door not closing. However I can only afford the time and money for one fix at a time. There are huge safety issues here and toyota should be held responsible.

Noticed a vibration starting on a 2007 toyota sienna xle. Initially thought it to be tire related. Upon investigation noticed the left rear wheel was too hot to touch. Revealed that the brake assembly had seized and was causing the brakes to overheat (blue dick and cylinder). Toyota claims they have seen this on many sienna's and they regularly lube the slides that mount the wheel cylinder. Mine had not seen lube. Brake pads on the remainder of the car were ~ 50%. I believe had I not found this, there would have been a fire (it was that hot). Now I'm stuck on my $ to pay almost $1000 for new brakes (opted to overhaul the other three to eliminate the same problem elsewhere).
