From owner reports, verbatim
I was driving down the highway at 70 mph and it was windy at the same time. Out of no where my sunroof window exploded shattering the glass. Luckily I usually keep the cover close. It sounded a gun shot that went off. There was nothing around me that would come down and break the window of the sunroof. It just happened out of no where.
DRIVING ON 285 EAST IN ATLANTA GA 11/29/2018 WHEN MY LEXUS IS 300 SUNROOF EXPLODED. ALL WINDOWS WERE CLOSED TEMPERATURE WAS 37 DEGREES. IT SOUND LIKE A GUN WENT OFF. GLASS FELL FROM THE ROOF AND PIECE OF THE GLASS WENT IN MY LEFT EYE. I MADE APPOINTMENT FOR THE EYE DOCTOR FOR 11/30/2018

Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
WHEN I ACCELERATE FROM A STOP OR WHILE MOVING ON A ROADWAY, THE ENGINE SEEMS TO STALL. I'M NOT TALKING ABOUT THE NORMAL TURBO SPOOLING STALL. IT LASTS FOR ABOUT 3 TO 5 FULL SECONDS. WHEN YOU NEED POWER TO PREVENT AN ACCIDENT, YOU CAN'T AFFORD THAT TIME LAG, AS IT COULD CAUSE YOUR DEATH. THE DEALER TOLD ME THAT LEXUS SAYS IT'S NORMAL, THEY ALL DO IT. I DON'T FEEL ANY MANUFACTURER WOULD DELIBERATELY BUILD AND SELL A VEHICLE THAT WOULD PUT THE OCCUPANTS IN DANGER OF POSSIBLE DEATH. THE DEALER PICKED UP THE CAR AND AFTER FIVE DAYS CALLED ME TO SAY NOTHING IS WRONG AND THEY CAN'T FIX THE PROBLEM BECAUSE LEXUS COMPANY SAYS IT'S NORMAL. AT THIS POINT I'M REFUSING TO DRIVE THE CAR, IT'S EXTREMELY DANGEROUS. I HAVE ONLY DRIVEN IT ABOUT 188 MILES SINCE BUYING IT ALMOST 1 MONTH AGO. I CALLED THE DEALER ABOUT MY CONCERN AFTER HAVING THE CAR ONLY 20 DAYS.
