 There was a pin hole puncture in the flexible material the oil cooler is made of. the result of this is that all the oil is forced out of the engine very quickly under high pressure. there was no warning until i heard engine noise. i had the van towed in and had the part replaced. the current factory authorized part is now made out of metal. the dealership then informed me that because of the failure of the part i would need a new engine.it will cost $10,000. i asked if there was anything i could have done differently to prevent this i was told no. my engine is still under warranty but the part that caused it is not. i realize parts break but this part is not a maintenance part and the expected outcome of its failure is engine replacement. this i have found from experienced auto people is common knowledge. i believe this is a defect that toyota knows about and is willing to ignore by invoking their warranty as a reason to allow this to happen to unsuspecting owners. oh, when i contacted toyota for help with my $10,000 problem, they offered me dinner. at this point i own a $30,000 piece of junk ( i owe $20,000) none of this would have occurred if the part had been made out of metal originally or if there was some kind of safeguard built in to warn you of the potential problem. unfortunately that is not the case. please help. *tr

 We have owned the sienna for 4 years and 53,000 miles without incidence. we have had it serviced by the toyota dealer and have had all scheduled maintenance. one afternoon, after driving the sienna all day, we pulled it into our driveway (which is on a slight incline) and placed it into park. after doing this, instead of the brakes being applied, the sienna rolled back as though it were in neutral. we brought the sienna to the toyota dealer who inspected it. they told us the pin that enables the brakes upon placing the sienna in park was completely shot and the entire transmission would need to be replaced. the service manager said he has never seen something like this before and that these pins don't wear out over time. the service manager also told us that you would only see damage to the pin if you were driving the car and then suddenly put it into park while moving at a high speed. the service manager contacted the offices of toyota corporate and had the case reviewed. it was determined by toyota corporate to be related to the warranty and they are replacing the entire transmission. *tr

 Tl- the contact owns a 2008 toyota sienna. while driving approximately 65 mph, the engine stalled with the illumination of the entire instrument panel. the vehicle failed to restart and was towed to an authorized dealer for diagnostic testing. the technician was unable to detect a trouble code. the malfunction occurred six times on the same day. the engine restarted each time the failure occurred and the vehicle was taken to a different dealer who could not locate a problem. the contact planned to take the vehicle for a third opinion to possibly locate the consistent failure. the manufacturer was notified of the problem. the approximate failure mileage was 34,680. rvk

 Piston slap on toyota 3.5 l v6 since new. very loud when cold in cooler temperatures..ca arbitrator agrees with toyota that this is normal for this engine. i cannot sell this car with this noise but toyota doesn't care. toyota has had a few complaints but no failures yet. piston slap wears the piston prematurely and could in my opinion lead to failure. this is my 2nd complaint to you people for the same issue. *tr

 2008 toyota sienna with approx. 45k miles. driving down highway after wedding. traction control light comes on. a minute later, check engine light comes on. half mile from exit, decide to take exit to see what's going on. as reach gas station right off exit, oil light comes on. check oil and see no oil in engine. oil splashed on tailgate. determine oil flowing from engine. toyota acknowledged problem with rubber oil hose and sent tow truck. loss of all oil without indication until engine failure. same v6 engine as recalled in camry and avalon. this is a serious problem requiring complete engine replacement. this is unsafe--sudden engine failure without indication at highway speeds and oil spill to exhaust components of engine could have caused accident or fire!

 In the summer of 2009 my toyota 2008 sienna xle awd engine speed slowly started to climb without my foot on the gas pedal. i don't remember the exact sequence of events that followed but i believe i placed it into neutral, stopped, placed it into park (automatic transmission) and turned the engine off then on again. after that the engine responded only to my actions on the gas pedal. it did occur to me that the pedal could have been caught under the floor mat so i checked its position and it was some distance from the pedal and could not have been the cause. i have owned this vehicle from new in may 2008 and this undirected acceleration has only occured once. the car has just completed 20,000 miles. i reported this to the dealer who serviced my car for the 20,000 mile interval and via toyota's web site but i want to make sure you are aware that sienna vans can also have this problem.

 Driving my 2008 toyota sienna and it felt funny and i heard some rattling from under the hood. no idea what the problem was but i knew that something was definitely wrong. i checked the oil and the dip stick was completely dry! i put in a few quarts of oil and it came out all over underneath the car as i was driving. had it towed to the dealer- they told me it was a faulty rubber oil line. i looked it up online and see that toyota had not yet issued a recall but is replacing it in some vehicles. the 2008 toyota sienna is not mentioned - but clearly should be. this is a van that i drive my 2 children around - very clearly a safety issue if i did not recognize soon enough that the engine had no oil!
