The engine shuts off for a second while driving
My car powers off while driving and then cuts back home within a second. It also has electrical issues the lights so flash during the night when you’re driving and then the front and shakes so bad that it shakes you just about off the road when you hit the brakes
THE CFEI (CERTIFIED FIRE & EXPLOSION INVESTIGATOR) FIRE LIEUTENANT/INVESTIGATOR WITH THE CITY OF FT. LAUDERDALE'S FIRE DEPT, WHO ALSO RESPONDED TO MY 911 CALL, HAD POINTED OUT AND EXPLAINED TO ME THE INTENSITY OF FLAME, HEAT AND BURN PATTERN IN THE ENGINE AND STATED THAT THIS WAS CAUSED BY A MECHANICAL ENGINE MALFUNCTION. WHAT HAPPENED: I HAD JUST DRIVEN MY 2012 LEXUS RX350 A SHORT DISTANCE ON THE HIGHWAY WHEN I PULLED INTO A 7-11 PARKING LOT NOT FAR FROM THE GAS PUMPS AND PUT THE CAR IN PARK. WITH THE ENGINE STILL RUNNING, I OPENED MY DRIVERS SIDE WINDOW TO TALK TO A FRIEND WHEN I IMMEDIATELY SMELLED SOMETHING BURNING. I FILED A REPORT WITH LEXUS THE VERY NEXT DAY AND RECEIVED A LETTER 3 WEEKS LATER. THEIR LAST PARAGRAPH SAYS "WE UNDERSTAND THAT YOU REPORTED THIS TO GEICO AS WELL. IF THEIR INVESTIGATION HAS REVEALED ANY EVIDENCE OF PRODUCT LIABILITY, WE WILL GLADLY REVIEW THAT INFORMATION." I CALLED OUT TO HIM AS HE WAS WALKING FROM HIS VEHICLE TOWARDS MY CAR AND YELLED OUT TO HIM THAT SOMETHING SMELLED LIKE IT WAS BURNING. HE THEN TOLD ME TO RELEASE THE HOOD BECAUSE HE NOTICED SMOKE COMING FROM THE ENGINE. HE SLIGHTLY RAISED THE HOOD, SAW A FLAME, SLAMMED THE HOOD SHUT, THEN HE YELLED OUT TO ME "GET OUT OF THE CAR NOW YOUR ENGINE IS ON FIRE". I JUMPED OUT, CALLED 911, THEN STARTED TAKING PHOTOS WITH MY PHONE WHILE WATCHING AS MY VEHICLE BECAME ENGULFED IN FLAMES AND SMOKE. FIRST I HEARD THE TIRES BLOW OUT THEN I HEARD THE WINDSHIELD BLOW OUT. MY FRIEND SAW THE FLAMES WHEN HE LIFTED THE HOOD AND SAID HE OBSERVED THAT THE FIRE WAS BURNING IN THE CENTER OF THE MOTOR AT THE FUEL MANIFOLD. THE FIRE DEPT ARRIVED ABOUT 5-7 MINUTES LATER AND PROCEEDED TO TRY TO PUT OUT THE FIRE. THE CAR IS A TOTAL LOSS!
HI, I WOULD LIKE TO INFORM YOU ABOUT A SERIOUS SAFETY ISSUE I DISCOVERED IN THE LEXUS RX350, THE CAR IS KEYLESS AND YOU JUST NEED TO PUSH A BUTTON TO START AND SHUT OFF THE ENGINE. THE SAFETY PROBLEM IS THAT THE CAR WILL SHUT OFF WHEN PUSHING THE BUTTON EVEN IF THE CAR IS STILL IN D=DRIVE AND THE CAR WILL ROLL BACK IF PARKED ON A SLOPE LIKE A DRIVEWAY ETC. IT IS EXTREMELY DANGEROUS AS KIDS CAN BE BEHIND THE CAR. PLEASE CHECK THIS SAFETY ISSUE. THANK YOU *TR
I WAS TOLD THAT A CIRCUT BREAKER FAILED UNDER THE DASH ,AS TO THE CAUSE. I BOUGHT THIS CAR NEW AND HAD SOME STRANGE ELECTRIAL ISSUES. THE CAR WAS A TOTAL LOSS. *TR
