2007 TOYOTA SIENNA Engine And Engine Coolingengine Problems

2007 TOYOTA SIENNA ENGINE STOPPED, AND FAILED TO START WITHIN ABOUT 15 MINUTES AFTERWARDS AT HOT WEATHER ABOVE 95F WITH AIR CONDITIONING ON. *KB

PURCHASE A 2007 TOYOTA SIENNA MINIVAN IN DECEMBER 2007 WITH ALMOST 20,000 MILE IN IT. AFTER PURCHASE NOTICE THAT WHEN ENGINE IS COLD IT SOUNDS LIKE A DIESEL ENGINE UNTIL IT WARMS UP. ALSO NOTICE WHAT FEELS LIKE A SLIP IN THE TRANSMISSION IN LOWER GEAR. THIS HAPPENS IF FOLLOWING BEHIND SOMEONE AND THEY TURN U NEED TO SLOW DOWN. WHEN U ACCELERATE TO GET BACK UP TO SPEED THERE IS A DELAY OR A SLIP BEFORE TRANSMISSION ENGAGES, COMPLAINED WITH THE LOCAL DEALER (ANDY MOHR TOYOTA) WHERE PURCHASE FROM. WE HAVE COMPLAINED SINCE DAY ONE OF OWNERSHIP. TOYOTA DEALERSHIP STATES THAT THE VEHICLE HAS A MEMORY TRANSMISSION AND LEARNS YOUR DRIVING HABITS. WELL ME AND MY WIFE DON'T DRIVE THE SAME AND NEITHER DOES ANYONE ELSE. NO PEOPLE DRIVE THE SAME AND WHY WOULD SOMEONE MAKE A VEHICLE LIKE THIS. THEY ALSO STATED THAT THERE IS NO FIX AT...

I BOUGHT A SECOND HAND 2007 TOYOTA SIENNA LE IN JUNE 2009. THE VEHICLE HAD ABOUT 49,000 KM. I NOTICED THAT VEHICLE HAD PRODUCED UNUSUAL NOISE WHEN STARTED AT COLD. IT SOUNDED LIKE DIESEL ENGINE. I TOOK A VEHICLE IN TO A TOYOTA DEALER AND THEY ATTEMPTED TO CORRECT THE PROBLEM. APPARENTLY, THERE IS A TSB ISSUED ON THIS PROBLEM. ALTHOUGH I APPRECIATE THE DEALER'S HONEST EFFORT IN CORRECTING THE PROBLEM, THE NOISE IS STILL THERE WHEN ENGINE IS STARTED AT COLD. *TR

I HAVE A 2007 TOYOTA SIENNA. WHEN THE ENGINE IS COLD AND STARTED I GET A NOISE THAT SOUNDS LIKE A LIFTER PROBLEM. ALTHOUGH THE WEATHER WILL EFFECT THE INTENSITY AND DURATION OF THIS NOISE IT IS ALWAYS THERE. THE TOYOTA DEALERSHIP I TOOK IT TO HAD A FACTORY ENGINEER COME OUT AND HE HEARD THE NOISE AND SAID IT WAS NORMAL AND ATTRIBUTED IT TO "PISTON-SLAP". AT THIS TIME THEY ARE TELLING ME THERE IS NO REPAIR FOR THIS CONDITION. THEY ACKNOWLEDGE THERE IS A NOISE BUT THEY SAY THEY CAN DO NOTHING ABOUT IT. THIS NOISE DEVELOPED APPROXIMATELY AROUND 20,000 MILES ON THE VEHICLE. OTHER SIENNA'S THAT ACQUAINTANCES OWN DO NOT HAVE THIS PROBLEM. SOME MORNINGS WHEN IT IS COLD OUT THE NOISE IS SO LOUD IT TURNS HEADS AS I DRIVE DOWN THE STREET. EVIDENTLY THIS IS A PROBLEM THAT TOYOTA KNOWS ABOUT BUT REFUSES TO FIX....

2007 TOYOTA SIENNA MADE A PINGING SOUND WHEN FIRST STARTING THE VEHICLE. CONSUMER STATES THAT THE DEALER STATED THAT THIS IS NORMAL WHEN THE ENGINE WAS COLD. DEALER CALLED IT A PISTON SLAP. FINALLY DEALER STATED THE VEHICLE HAD A PROBLEM. *KB
