Toyota Corolla electrical problems

THE DISPLAY SCREEN FOR THE RADIO, NAVIGATION, MAINTENANCE REMINDERS, HANDS FREE PHONE USE, BACK-UP CAMERA, ETC. SUDDENLY STOPPED WORKING WHEN STARTED MY CAR. THE SCREEN ONLY SHOWS AN ICON WITH A STATUS BAR THAT MAKES IT APPEAR THAT THE COMPUTER THAT OPERATES THIS SYSTEM IS TRYING TO RESTART. THE SCREEN ITS SELF WORKS, BUT THE COMPUTER WON'T BOOT-UP. THIS IS DISTRACTING WHILE DRIVING, AND PREVENTS THE USE OF ALL THE SAFETY FEATURES THAT RELY ON IT'S FUNCTION. I HAVE DONE EXTENSIVE READING ON THE INTERNET AND HAVE FOUND THAT THIS IS A COMMON PROBLEM IN 2014-2016 TOYOTA VEHICLES THAT HAVE THE PREMIUM ENTUNE SYSTEM WITH NAVIGATION. THEY ADMITTEDLY STATE THAT THE FUGITSU COMPONENT IS FAULTY AND THEY HAVE SENSE STARTED USING A PANASONIC UNIT TO AVOID FUTURE PROBLEMS. TOYOTA PRICES THE REPLACEMENT PART AT $3450. THIS IS UNACCEPTABLE, WHEN THEY KNOW THAT THE PROBLEM IS NOT THE FAULT OF THE CAR OWNER, BUT RATHER A FAULTY PART THAT WAS USED DURING THE MANUFACTURE OF THE VEHICLE. ACCORDING TO THE POST OF ONE TOYOTA TECHNICIAN, TOYOTA HAS REPLACED 1 MILLION OF THESE UNITS, BUT UNLESS THE VEHICLE IS STILL UNDER WARRANTY THEY REFUSE TO COVER THE REPAIR COST BECAUSE TOYOTA DOES NOT THINK THIS MALFUNCTION IS A SAFETY ISSUE A RECALL OR WARRANTY EXTENSION HAS NOT BEEN ISSUED. I THINK IT IS A SAFETY ISSUE WHEN THE HANDS-FREE FUNCTION DOES NOT WORK AND THE REVERSE CAMERA DOES NOT WORK. ALSO AN INOPERABLE NAVIGATION SYSTEM COULD BE A SAFETY ISSUE TOO. I HAVE TRIED TO RESET THE RADIO, DO A HARD RESET BY HOLDING THE POWER BUTTON AND DISCONNECTING THE BATTERY. NOTHING WORKS. I CALLED TOYOTA AND THEY QUOTED ME MORE THAN $3600 FOR THE REPAIR. THIS IS UNACCEPTABLE.

WHEN I AM DRIVING MY 2010 TOYOTA COROLLA S ON THE HIGHWAY AT SPEEDS OF OVER 50 MPH IT DOES NOT STAY STRAIGHT. IT REQUIRES ALOT OF STRENGTH TO KEEP IT STRAIGHT. IT FEELS LIKE THE CAR IS BEING MOVED TO THE RIGHT OR LEFT BY WINDS. FEELS VERY UNSAFE TO DRIVE. THE STEERING WHEEL IS SO STIFF TO TURN SOMETIMES. I HAVE DONE THE WHEEL ALIGNMENT SEVERAL TIMES AND PUT ON NEW TIRES RECENTLY BUT THE PROBLEM STILL REMAINS. VERY UNSAFE TO DRIVE AND I GET VERY TIRED AFTER DRIVING AT HIGHWAY SPEEDS JUST MAINTAINING IN MY OWN LANE. THE DEALER'S ARE NOT MUCH HELPFUL AT ALL WITH THIS. I'VE READ ONLINE ALOT OF PEOPLE HAVING PROBLEMS WITH THIS MAKE AND MODEL WITH THE STEERING. THERE NEEDS TO BE AN INVESTIGATION ON THIS SOON BECAUSE IT'S VERY DANGEROUS TO DRIVE.

AUDIO/NAVIGATIONAL UNIT IS NOT FUNCTIONAL, RENDERING ALL FEATURES (OTHER THAN ACTUAL MOBILITY) NON-FUNCTIONAL - I TRAVEL/LIVE IN A HANDS FREE CITY/STATE, AND SPECIFICALLY PURCHASE THIS VEHICLE FOR AUDIO/NAVIGATIONAL UNIT AND THE BLUE TOOTH TECHNOLOGY. ALSO, FLASHES LIGHT UNCONTROLLABLY WHILE IT CONSTANTLY REBOOTS (DISTRACTION - ESPECIALLY AT NIGHT AND DURING INCLEMENT WEATHER). CANNOT ACCESS DIAGNOSTIC INFORMATION ON VEHICLE (TIRES, ENGINE, ETC.) AS PROMOTED/PROMISED FROM ENTUNE SOFTWARE. TOYOTA HAS A KNOWN ISSUE BUT WILL NOT REPLACE THE UNIT (T-SB 0172.16) AND STATES IT WAS DUE TO WARRANTY EXPIRATION, BUT NEVER NOTIFIED CUSTOMER (I.E. ME) ABOUT ISSUE EVEN WHEN I REACHED OUT TO TOYOTA TO RESOLVE. EVEN WHEN I NOTIFIED A LOCAL SERVICE/DEALERSHIP, THEY IGNORED MY SAFETY CONCERNS. ORIGINALLY TOYOTA SAID THEY WOULD HELP (SEPTEMBER), NOW (DECEMBER) THEY ARE STATING THEY WILL NOT.

I OWN A 2009 COROLLA THAT HAS 108,000 MILES. I TOOK IT TO THE DEALER FOR THE AIRBAG RECALL FIX, AND IT ALSO HAD THE ENGINE CHECK LIGHT ON. THE DEALER SAID THAT THE OBD-II CODE P0354 CAME UP IN THE DIAGNOSTICS AND THE VEHICLE NEEDED A NEW ENGINE WIRE HARNESS AT A COST OF $2,000 DOLLARS. I DID MY OWN RESEARCH AND FOUND THIS TOYOTA TECHNICAL SERVICE BULLETIN LINK THAT DESCRIBES EXACTLY THE PROBLEM AND ALSO INCLUDES MY CAR'S VIN. HTTP://ALFLASH.COM.UA/REFER/T-SB-0379-08.PDF APPARENTLY,TOYOTA KNEW OF THE WIRING HARNESS PROBLEM, BUT THEY CHOSE TO CONCEAL IT AND FIX ONLY IF THE CUSTOMER COMPLAINED. THEY EXPECTED THE CUSTOMER TO PLAY DETECTIVE AND FIND THEIR LATENT DESIGN FAULT! I HAVE OWNED FIVE OTHER CARS SINCE 1973, ONE FOR 23 YEARS, AND I NEVER HAD TO REPLACE THE ENGINE WIRE HARNESS!

I WANT TO REPORT THAT I FOUND A LOOSE BOLT POKING OUT OF THE DRAIN HOLE ON THE REAR PASSENGER DOOR OF OUR 2015 TOYTOTA COROLLA. IT WAS ORIENTED IN SUCH A WAY THAT ONLY THE THREADED END WAS POKING OUT THE HOLE AND HELD INSIDE THE DOOR BY THE BOLT HEAD. I TOOK IT TO THE DEALER AND AS A COURTESY THEY REMOVED THE DOOR PANEL AND DETERMINED IT HAD COME FROM ONE OF THE WINDOW PARTS (REGULATOR OR MOTOR). THEY REINSTALLED AND TIGHTENED THE BOLT. I READ ON THE INTERNET THIS WAS A SERIOUS PROBLEM WITH PREVIOUS TOYOTAS AND CREATED SAFETY CONCERNS. THIS MAY BE A CONTINUED PROBLEM WITH TOYOTAS. IT WAS OBVIOUSLY A VERY SMALL CHANCE THAT THE BOLT ACTUALLY LANDED IN A FASHION TO PARTIALLY STICK OUT OF THE DRAIN HOLE SO I WAS ABLE TO SPOT THIS, SO I CAN'T HELP BUT WONDER IF OTHER WINDOW BOLTS IN THE CAR HAVE, OR WILL, COME LOOSE AND FALL INTO THE INTERIOR OF THE DOORS WITHOUT DETECTION. THIS MAY ALSO BE THE CASE WITH MANY OTHER COROLLAS SOLD. BOLTS THAT BECOME LOOSE AND FALL OFF OF WINDOW PARTS COULD LEAD TO INADVERTENT AND DANGEROUS FAILURE OF WINDOWS ON THE ROAD. I SUGGEST YOU INVESTIGATE THIS POTENTIAL SAFETY ISSUE.

MY CAR WHEN LEFT ON IN PARK WILL SHUT OFF BY ITSELF AFTER A SHORT TIME (THIS HAS HAPPENED TWICE), TODAY WHEN I WAS IN DRIVE AND ABOUT TO PULL OUT OF WORK IT SHUT OFF. I RESTARTED IT AND EVERYTHING WORKED FINE. THE CAR WAS NOT MOVING WHEN IT SHUT OFF, BUT BOTH TIMES THE ENGINE AND OIL LIGHT CAME (THERE MIGHT HAVE BEEN ANOTHER LIGHT) ON BUT WHEN RESTARTED THEY WENT OFF.
