Structure

51 reports2 crashes1 fire1 related recall
“WITHIN A TWO MINUTE PERIOD, BOTH SLIDING DOORS THAT WERE PREVIOUSLY FUNCTIONING, SUDDENLY FAILED IN A CLOSED POSITION. THEY COULD NOT BE OPENED MANUALLY USING THE DOOR HANDLES FROM BOTH INSIDE AND OUTSIDE THE VEHICLE, OR BY ATTEMPTING TO ACTUATE THE RIGHT SIDE POWER DOOR. THE POWER DOOR LOCKS HAD NO EFFECT. THERE WAS NO DAMAGE TO THE VEHICLE THAT COULD HAVE CAUSED MECHANICAL DOOR FAILURE, OR OTHERWISE. NON FUNCTIONING OR JAMMED DOORS SHOULD CONSTITUTE A SAFETY ISSUE AND SHOULD BE RECALLED. IF THE VEHICLES FRONT DOORS WERE COMPROMISED IN A COLLISION, PASSENGERS SHOULD BE ABLE TO EXIT THROUGH THE REAR DOORS, BUT WOULD NOT BE ABLE TO WITH THIS MECHANICAL DEFECT. THE FACT THAT THE DOORS CANNOT ALSO BE OPENED USING EXTERIOR HANDLES INCREASES THE RISK OF ENTRAPPING PASSENGERS. TOYOTA SHOULD CONSIDER THIS A SAFETY RECALL AND REPAIR ALL FAULTY DOORS, OF WHICH THERE ARE MANY COMPLAINTS FILED HERE AND ON ONLINE FORUMS. I AM CURRENTLY HAVING TO PAY FOR THIS REPAIR MYSELF, AS TOYOTA HAS INFORMED ME THAT THERE ARE NO CURRENT RECALLS. THANK YOU FOR YOUR CONSIDERATION. *TR”

“I HAVE 4 BRIDGESTONE INSIGNIA TIRES. NOT SURE OF MILEAGE BUT I WILL GO BACK TO THE DEALER ON MONDAY TO CONFIRM, HOWEVER I WILL GUESS ABOUT 25K TO 35K. THE TREAD LOOKS VERY GOOD. I HAVE STEEL WIRES COMING OUT OF THE SIDEWALL. THERE ARE ABOUT A DOZENS WIRES BETWEEN 2" AND 8" HANGING OUT. I NOTICED IT BECAUSE YOU CAN HEAR THE WIRES SLAPPING THE FENDER AND TIRE WELL AS ROTATION OCCURS. I HOPE THE FACTORY RESPONDS IN A POSITIVE WAY, WE WILL SEE. [XXX] *TR”
