CAR SHAKES VIBRANTLY AND MAKES A RATTLING NOISE WHEN STARTING. DOES IT AT TIMES WHEN COMING TO A STOP ALSO. ENGINE LIGHT COMES ON. HAVE HAD EXHAUST MANIFOLD CHANGED AND TUNE UP BECAUSE SCANNER SHOW A MISFIRE ON A SPARK PLUG BUT NONE OF THOSE SEEMED TO FIX THE PROBLEM. IS THERE A RECALL ON THIS VEHICLE COMING SOON.

I WAS DRIVING MY 2011 LEXUS CT200H ON THE NJ TURNPIKE JUST OUTSIDE NYC. IT WAS A CLEAR DAY. THE TEMPERATURE WAS 85. SUDDENLY, I HEARD A LOUD "POP"--LIKE AN EXPLOSION.

I WAS DRIVING MY 2011 LEXUS CT200H ON THE NJ TURNPIKE JUST OUTSIDE NYC. IT WAS A CLEAR DAY. THE TEMPERATURE WAS 85. SUDDENLY, I HEARD A LOUD "POP"--LIKE AN EXPLOSION. I HAD JUST PASSED A TRACTOR-TRAILER AND THOUGHT IT HAD BLOWN A TIRE. THEN I STARTED TO HEAR WIND NOISE IN MY CAR. I PULLED OFF AT THE NEXT REST STOP AND DISCOVERED THAT MY SUNROOF HAD EXPLODED. THERE WAS A PIECE OF GLASS MISSING ABOUT THE SIZE OF TWO SOFTBALLS AND THE REMAINING GLASS WAS ALL SHATTERED. THE EDGES OF THE REMAINING GLASS WERE POINTED UPWARD. THERE WAS VERY LITTLE GLASS DEBRIS RESTING ON THE INSIDE COVER OF THE SUNROOF. THERE WAS NO EVIDENCE THAT ANYTHING HIT THE CAR. THE LEXUS DEALER HAS TOLD ME HE HAS NOT HEARD OF THIS PHENOMENON, ALTHOUGH IT HAS BEEN DOCUMENTED ONLINE. THE WASHINGTON DC LOCAL ABC TV AFFILIATE DID A STORY ON THIS TOPIC LAST SUMMER. ALSO, MY MECHANIC HAS TOLD ME THAT HE SPOKE WITH A LOCAL LEXUS MECHANIC WHO SAID HE HAS SEEN THIS A FEW TIMES BUT THAT LEXUS DENIES IT IS A PROBLEM. HAD THE INSIDE COVER OF MY SUNROOF BEEN OPEN, THIS COULD HAVE CAUSED A VERY SERIOUS ACCIDENT...UPDATED 03/15/16 *BF UPDATED 10/26/2017*CN
