2007 LEXUS RX350 Electrical Systemignition Problems

LOST POWER ON HIGHWAY MY RX350 (2007) LOST POWER GOING 65 MPH ON A HIGHWAY, AND BEGAN TO SLOW DOWN QUICKLY. WITH A TRUCK ON ONE SIDE AND ANOTHER BARRELING DOWN MY BEHIND, I TRIED TO ACCELERATE BUT THE VEHICLE BEGAN TO SHUDDER AND SHAKE VIOLENTLY! BY SOME MIRACLE, I MANAGED TO SWERVE TO THE SHOULDER ACROSS 2 LANES, AND AVOIDED GETTING HIT BY INCHES! GOT THE VEHICLE TO THE LEXUS DEALER AND THEY FOUND OUT THAT IT WAS A PREMATURE IGNITION COIL FAILURE - THE VEHICLE HAS ONLY ABOUT 42000 MI ON IT. ASKED LEXUS CORPORATE TO: 1) DO A FULL INVESTIGATION SO AS TO PREVENT SIMILAR LIFE THREATENING SAFETY FAILURES, AND 2) REIMBURSE THE COST OF REPAIR AT A MINIMUM LEXUS CUSTOMER SERVICE RESPONDED WITH A VERBAL OFFER TO BEAR 10% OF THE COST OF REPAIR - AND NO PROMISE OF ANY INVESTIGATION! TALK ABOUT ADDING INSULT TO...

I HAVE NOW HAD TO REPLACE 3 IGNITION COILS. I ONLY HAVE THE PAPERWORK FOR 2 TIMES, BUT EACH TIME THE CAR BEGAN TO RUN ROUGH AND THE ENGINE WENT OFF AT STOPS, AND THE ELECTRICAL SYSTEM LIGHT WENT ON. THE FIRST TIME THIS HAPPENED, WHICH I THINK WAS IN 2010, THE LEXUS TECHNICIAN SAID IT WAS A FLUKE. THE SECOND TIME (ABOVE DATE), THE LEXUS TECHNICIAN SAID HE WAS BEGINNING TO SEE A LOT OF IGNITION COIL FAILURES. THIS LAST TIME (TODAY), THE TECHNICIAN SAID REPLACING FAULTY IGNITION COILS IS NOW COMMON, AND JUST A PART OF MAINTENANCE. HE ALSO SAID SOME PEOPLE WERE CHOOSING TO REPLACE ALL 6 OF THEM AT ONCE SO THAT THEY WOULDN'T BE STRANDED AT NIGHT OR ON THE ROAD, AND TO SAVE MONEY. OBVIOUSLY, THERE'S A MAJOR PROBLEM WITH LEXUS RX350 IGNITION COILS. *TT
