“The car is giving problems in the engine, it's consuming way too mucho oil. I found out that there was a recall this Monday oct 18, 2021, and they told me that I can not participate because my car exceeds the miles limit by 6k miles, which I know, but if I knew that, I would've taken the car to a Toyota Dealer earlier. Is it possible to have it repair by some empathy and understanding of not receiving anything on mail or alert whatsoever. Please I beg for help, it's my only vehicle, the one I go to work to. I will loose my job if this don't get fixed because I can't afford to pay an engine repair on my own at this moment! Thank you for understanding!”

“LAST NIGHT WE WENT OUT. THE CAR WAS PARKED AT AN EVENT FOR A COUPLE HOURS, THEN WE WERE HEADED FOR DINNER WHEN THE DASHBOARD LIT UP, THE POWER STEERING WENT OUT AND THE CAR SUDDENLY LOST POWER. FORTUNATELY WE WERE ON A LOW TRAVELED CITY STREET AND WERE ABLE TO PULL OFF FOR SAFETY. IF WE HAD BEEN ON THE FREEWAY, I HAVE NO DOUBT THAT, IN THE DARK, ON A SATURDAY NIGHT, THIS INCIDENT WOULD HAVE RESULTED IN INJURY OR WORSE. THE PICTURES OF THE WIRING ARE ATTACHED. SOMETHING HAD EATEN THEM - THESE WIRES, DUE TO ANOTHER INCIDENT, HAVE BEEN CONFIRMED AS BEING THE EDIBLE ONES THAT ARE CAUSING SO MANY PROBLEMS IN MANY CARS. THE CAR HAD BEEN DRIVEN REGULARLY, INCLUDING DURING THE DAY OF THE LATEST INCIDENT, WITHOUT PROBLEMS. IT APPEARS, BASED ON THE TOTAL SEPARATION OF THE WIRES FROM THE ALTERNATOR THAT SOMETHING GOT IN WHEN THE CAR WAS PARKED AT THE EVENT. ALSO, WE WERE ONLY A COUPLE MILES AWAY WHEN ALL HELL BROKE LOOSE. LAST TIME, SOMETHING ATE THE AC WIRES, SO THERE WERE NO SAFETY ISSUES. THIS TIME, THE CAR BECAME SUDDENLY UNSAFE WHILE DRIVING. AT THIS POINT, I'M AFRAID TO DRIVE IT UNLESS I DO A THOROUGH INSPECTION OF THE WIRING SYSTEM BEFORE EVERY USE, WHETHER I AM…”

“TWICE MY CAR UNEXPECTEDLY ACCELERATED. THE FIRST TIME, MY CAR WAS IN REVERSE, AND MY FOOT WAS ON THE BRAKE. THE ENGINE SUDDENLY REVVED. I PUT THE CAR IN PARK AND TURNED IT OFF. THE SECOND TIME, I WAS IN DRIVE WITH MY FOOT ON THE BRAKE. THE ENGINE SUDDENLY REVVED. I PUT THE CAR IN PARK AND TURNED IT OFF. NEITHER TIME DID MY CAR MOVE. I TOOK THE CAR TO THE DEALERSHIP. THEY FOUND NOTHING WRONG. BECAUSE I NO LONGER FELT SAFE, I SOLD THE CAR BACK TO THE DEALERSHIP. THE CAR HAD APPROXIMATELY 2,200 MILES ON IT. THE CAR COST ABOUT $18,000. THE DEALER BOUGHT IT BACK FOR $12,000.”
