2008 Lexus LS460L

WE HAD LACK OF POWER ENGINE AND STEERING PROBLEMS IN THE PAST WITH THIS VEHICLE. WE FILED A LEMON LAW AND SUPPOSEDLY THEY FIXED IT. NOW THE PCS, VSC, ANTI SKID, AIR BAGS, BRAKES, ANTI-LOCK BRAKES AND OTHER ALARMS CAME ON AGAIN. THIS TIME THE BEEPING SOUND IS NOT ON CONTINUOUSLY BUT THE ALARMS ARE ON ALL THE TIME. THE POWER ASSIST ON THE BREAKS AND THE ANTI-LOCK BRAKE STOPPED WORKING ALL OF A SUDDEN. WE NOTED THE REAR DRIVER SIDE WINDOW WORKS OK, THE FRONT DRIVER SIDE WINDOW DOES NOT GO UP OR DOWN AUTOMATICALLY YOU HAVE TO KEEP THE BUTTON PRESSED, THE FRONT AND REAR PASSENGER WINDOWS DO NOT GO DOWN ALL THE WAY AND WHEN THEY GO UP THEY BOUNCE BACK HALF THE WAY. WE CHANGED THE BATTERY THINKING THAT WAS THE PROBLEM BUT THE PROBLEM CONTINUED. WE INSPECTED THE FLUID LEVELS AND ALL BREAKS AND ALL OTHER FLUIDS LEVELS ARE OK. AT THIS TIME WE ARE VERY SCARED OF THIS VEHICLE SINCE THE BREAKS CAN STOP WORKING ANYTIME. IF YOU KNOW IT IS DOING IT YOU CAN DRIVE EXTREMELY CAREFUL AND VERY SLOWLY, BUT THE PROBLEM CAN APPEAR ANYTIME. IF THE BREAKS STOP WORKING WHEN YOU REALLY NEED THEM IT COULD BE FATAL. WE SENT THE VEHICLE FOR INSPECTION THE FIRST TIME, BUT THE ALARMS WENT AWAY AND EVERYTHING WENT NORMAL AGAIN. THIS SECOND TIME THE ALARMS AND ALL MALFUNCTIONS STAYED UNTIL WE BROUGHT THE VEHICLE TO THE DEALER. THE BRAKES' ASSIST STOPPED WORKING ALL OF A SUDDEN, THE ANTI LOCK BREAKS AND STABILITY CONTROL STOPPED WORKING THIS SECOND TIME WITHOUT NOTICE. I HAVE NEVER SEEN SOMETHING AS DANGEROUS AS THIS ISSUE IN ANY CAR WE HAVE OWNED OR DRIVEN IN MY LIFE. THERE IS A MAIN DESIGN ISSUE. THE BREAKS AND ALL SYSTEMS SHOULD NOT SIMPLY STOP WORKING WHILE YOU ARE DRIVING. I SEARCH THE INTERNET AND THERE ARE MANY OTHER PEOPLE WITH THE SAME INTRINSIC PROBLEM. WE VIDEO TAPED THE PROBLEM AND TOOK PICTURES IF YOU NEED THEM, PLEASE EMAIL ME OR CONTACT ME. *TR
