| The vehicle engine stalls. this occurs intermittently especially when making turns. i had to press the gas pedal all the way down to accelerate. the vehicle brake lights do not come off for about 10 minutes when the engine and lights have been switched off. it is possible to start the car with the push button without pressing down on the gas pedal sometimes. | |||

| 5 month old toyota sienna 2011 stalled after the lights inside the dashboard (control panel) started blinking and then would not start again. it was towed to the dealer on 12/22/2010. dealer initially (on 12/27/2010) said it is due to water damage and engine has to be replaced. dealer was not able to find any evidence of sienna being submerged in water (as it did not go into any big puddle or deep waters). i opened a case with toyota on 12/28/2010. i was in touch with toyota dealer but case manager at toyota informed that they were unable to reach/speak to the dealer for 2 days even though they are both in california. she informed me that their policy is to concur with dealer without even looking at the report or talking to them and they would neither investigate nor inspect. my insurance company (aaa) performed visual inspection and found too many metal pieces inside the engine. insurance company also followed up with dealer and informed there are other cases where they had seen similar issue with toyota sienna 2011 and this does not seem to be a water damage. there has been neither an explanation nor a follow-up from toyota as to what the cause was. dealer reported back on 01/04/2011 and informed me that it might be a mechanical failure and toyota will fix it. i am now concerned about the safety of my family and anyone who drives sienna. what if stalls in the middle of freeway ? what if this happens again ? worried and tensed owner of toyota sienna 2011. | |||
