2010 LEXUS HS Complaints

WHEN AT A MID-SPEEDS (TYPICALLY 35 TO 50 MPH) AND ONE TRIES TO BRAKE ON A ROUGH, UNEVEN OR LOOSE GRAVEL SURFACE, THE CAR ACCELERATES AGAINST THE DRIVER'S BRAKING. THIS IS PARTICULARLY PROBLEMATIC WHEN MAKING A TURN FROM A BUMPY OR UNEVEN ROAD. THE ACCELERATION FORCE OVERPOWERS THE DRIVER'S BRAKING AND MAKES THE TURN DIFFICULT CAUSING THE DRIVER POTENTIALLY TO OVERSHOOT THE TURN. THIS ACCELERATION AGAINST BRAKING HAS ALSO OCCURRED ON STRAIGHT ROAD DRIVING WHEN ONE BRAKES FROM MID-SPEEDS ON UNEVEN, BUMPY OR LOOSE GRAVEL ROADS. THIS EVENT HAS OCCURRED REPEATEDLY IN SIMILAR CIRCUMSTANCES. *TR

NOT SURE WHAT HAPPENED BUT THE CAR RAN INTO A BARRIER POLE WHILE TURNING INTO THE PARKING GARAGE. THE FRONT BUMPER WAS DAMAGED. I CANNOT TELL IF IT WAS A PROBLEM WITH BRAKE OR NOT. *TR

BRAKES MOMENTARILY DON'T FUNCTION AS I DRIVE OVER UNEVEN ROAD. IT FEELS LIKE YOU ARE HYDRO-PLANNING(SKIDDING) EVEN THOUGH ROAD IS NOT WET. *JB

I PURCHASED A LEXUS HS250 IN OCTOBER 2009. SINCE THEN, I HAVE EXPERIENCED AT LEAST 6 OCCASIONS FROM THE END OF OCTOBER 2009 TO EARLY FEBRUARY 2010 IN WHICH I BRAKED WITH THE INTENTION OF COMING TO A STOP. THE VEHICLE BEGAN TO SLOW DOWN IN THE BRAKING PROCESS, THEN THE BRAKES STALLED FOR A FEW SECONDS BEFORE RESUMING THE BRAKING ACTION. IT IS UNEXPECTED AND DANGEROUS BECAUSE YOU DON'T KNOW IF YOUR BRAKES ARE COMPLETELY STALLING OR NOT. FOR A COUPLE OF SECONDS, EVERYTHING JUST GIVES WAY BEFORE THE BRAKES SEEM TO BEGIN WORKING AGAIN. IN THAT SITUATION, YOU DON'T KNOW WHETHER TO PRESS DOWN A SECOND TIME ON THE BRAKE OR TO PUMP THE BRAKE PEDAL OR NOT DO ANYTHING. WHEN THIS EVENT HAPPENS, YOU FEEL AS IF YOU HAVE ABSOLUTELY NO CONTROL OVER THE OPERATION OF THE VEHICLE, SIMILAR TO DRIVING ON A SHEET OF ICE, EXCEPT NONE OF THOSE SAFETY RULES SEEM TO APPLY HERE. THIS HAS HAPPENED ABOUT EVERY FEW WEEKS. I HAVE NOTICED THAT IT SOMETIMES HAPPENS WHEN I AM DRIVING OVER AN UNEVEN SURFACE, BUMP, OR A POTHOLE IN THE STREET WHILE BRAKING. WHILE I HAVE NOT BEEN INVOLVED IN A CRASH, IT HAS WORRIED ME THAT THIS COULD LEAD TO ONE. *JB
