In August 2025, AutoNation Toyota on Sahara, checked the VIN of my Toyota Sienna and contacted Toyota while I was present. Toyota confirmed a broken fuel-door hinge was covered under a Customer Support Program. Instead, AutoNation attempted to repair, rather than replace, the hinge. This caused the metal fuel cap door to end up bent, paint to be gouged out from the bottom of the fuel door area, misalignment of the fuel door, and therefore issues with the door’s sensor reading correctly. I took the van back until they received shipment of a new fuel cap door. After the attempted repair, since the fuel door no longer aligned, the safety sensors repeatedly activated which strained the sliding-door ECU. The passenger sliding door began freezing intermittently, forcing my children to exit through the trunk several times. Finally, the door opened on its own as I was driving down the street. These issues did not exist prior to dealership service and presented a clear safety concern. Between October and December, I received conflicting explanations from Gerald, James, Ivan, and Rudy at AutoNation Toyota regarding whether the issue involved the fuel door, ECU, motor, or general wear and tear. AutoNation repeatedly failed to return my calls or respond to the emails I sent them. Toyota Corporate also informed me the dealership was also not responding to their outreach attempts after I contacted them due to not being able to get ahold of AutoNation Toyota. I emailed four managers on October 15 with detailed documentation and received no response. My vehicle remains unsafe, unrepaired, and in the possession of AutoNation Toyota. I approve allowing it to be inspected. While at AutoNation, the vehicle driver could not open the passenger sliding door after AutoNation's attempted repair. They have had my van for 4 months now so no one else has looked at or inspected it. There were no warning lamps, messages or other symptoms of the problem prior to the failure.

PASSENGER SIDE POWER SLIDING DOOR CONSTANTLY MALFUNCTIONING. IT OPENED AFTER A BUMP WHILE TRAVELING 65 MPH ON THE INTERSTATE. WE HAD TO PULL OVER TO CLOSE THE DOOR. IT ALSO DEPLOYED THE WHEELCHAIR RAMP WHILE MOVING BECAUSE THE POWER DOOR IS THE SAME SIDE AS THE RAMP.. MAKE THE MANUFACTURER FIX IT OR MAKE THE WHEELCHAIR CONVERSION COMPANY FIX IT. SOMEBODY NEEDS TO FIX THIS BEFORE SOMEBODY DIES! ALL THIS RED TAPE AND ZERO ACTION IS INSANE. PEOPLE ARE GETTING INJURED WHILE THE FINGER POINTING IS HAPPENING. WHEN WILL SOMETHING BE DONE? HOW MANY INJURIES HAVE TO OCCUR BEFORE AN ACTION STEP OCCURS?

THEIR IS A RECALL ON THE AUTOMATIC SLIDING DOORS BUT TOYOTA HAS FAILED TO CORRECT THE ISSUE. THE BACK DOORS UNLATCH AUTOMATICALLY AND HAVE PROPELLED OPEN TWICE WHILE I WAS DRIVING MY CHILDREN!! I BROUGHT IT INTO SERVICE AND THEY TOLD ME THEY DISABLED THE ELECTRONIC OPENING FUNCTION AND I WOULD HAVE TO OPEN AND CLOSE THE DOORS MANUALLY UNTIL TOYOTA HAS PERMANENT SOLUTION. IT TURNS OUT THEY ONLY PRESSED THE POWER SWITCH ON MY DASH BOARD AND THE DOORS CONTINUE TO UNLATCH AUTOMATICALLY. I WILL MANUALLY CLOSE THE DOOR AND ONCE DRIVING I HEAR THEM TRYING TO OPEN. I'VE HAD TO PULL OVER AND MANUALLY SHUT THEM TIGHT BUT LAST NIGHT IT FLEW OPEN WHILE I WAS DRIVING WITHOUT ANY WARNING THAT IT HAD UNLATCHED!! I'M PAYING $420.00 A MONTH IN A LEASE CONTRACT FOR A CAR THAT IS UNSAFE. TOYOTA HAS FAILED TO REMEDY THE PROBLEM AND DEALERS REFUSE TO HELP ME GET OUT OF THIS VEHICLE DESPITE THE FACT THAT IT IS DANGEROUS!

2015 TOYOTA SIENNA MINI VAN BOUGHT NEW. STILL COVERED BY 36 MONTH WARRANTY WITH 30,000 MILES. POWER SLIDING DOORS UNDER RECALL. OBSERVED SIGNIFICANT RUST ON METAL PLATE BOLTED ON DOOR HINGE COVERING ELECTRICAL WIRES. IF METAL COVER RUSTS THRU, COULD LEAD TO SHORT AND ELECTRICAL DOOR MOTOR FAILURE. TOYOTA REFUSES TO REPLACE METAL COVER PLATE. I FEEL TOYOTA SHOULD HONOR WARRANTY AND REPLACED RUSTED PARTS.

MY 11-YEAR OLD SON GOT OUT OF THE FRONT PASSENGER SIDE OF OUR STAITIONARY MINIVAN (IN PARK BUT RUNNING), FOR ME TO DROP HIM OFF FOR A CELLO LESSON. HE OPENED THE REAR PASSENGER SIDE SLIDING DOOR TO GET HIS CELLO OUT. IT WASNT OPENING EASILY, SO I ALMOST SIMULTANEOUSLY PUSHED THE BUTTON ABOVE ME ON THE CONSOLE. AT THAT POINT THE DOOR STARTED TO CLOSE ON HIM. IT DID NOT STOP CLOSING AND WAS PRESSING HIM INTO THE DOOR FRAME. I DIDN'T REALIZE WHAT WAS HAPPENING, AND HE WAS TOO SHOCKED TO SCREAM. HE WAS TRYING TO STOP IT FROM CLOSING ON HIM, BUT IT KEPT CLOSING. I EXPECTED THAT THE DOOR WOULD AUTOMATICALLY SENSE A BLOCKAGE, STOP AND OPEN BACK. HE WAS ONLY OK BECAUSE HE WAS STRONG ENOUGH TO PRESS BACK, BUT HIS HIP WAS VERY BRUISED. I FINALLY REALIZED THAT THE DOOR WASN'T OPENING, AND PRESSED THE BUTTON AGAIN ABOVE ME AND THE DOOR STOPPED. IT STRIPPED THE WIRES IN THE DOOR, AND THE AUTOMATIC DOOR IS NOW BROKEN. THE ELECTRICAL OR SENSING SYSTEM IN THIS DOOR IS FAULTY.
