2009 Toyota Corolla Electrical System

I purchased my car in March 2023. From the first week, it wouldn't start sometimes. Id wait 5 minutes, then it would start fine. I thought it was when it got wet, at first. I also had a certain part replaced air flow compressor, possibly was called?, thinking this would fix it. It did not. In fact, the problem seemed to be happening more and more but, always, if I waited 5 to 10 minutes, sometimes messed around under the hood, it would start. This was not very comforting however, when it would stall at a light and not start right back up. I took it to AutoZone and was run on the diagnostics machine. Was told it needed new spark plugs and ignition coil packs. Which I got and replaced. Still happening. I took back to AutoZone, had it run again on diagnostic. This time it said battery. So I had a new battery put in. Still happening. All along, might I add, my fuses will blow randomly, my headlights And taillights will blow for no reason. One taillightooks like it melted through the plastic before it decided to blow. I e replaced some fuses, only to have blown again. I also have replaced the light bulb in taillight, only to have blown twice more. This is very dangerous, especially at a traffic light or, late at night if I need to go somewhere or leave somewhere And it won't start. I've been stuck in the middle of the road, on the wring sidevif the riad, in the midfle if a snowstorm, with it not starting for me. Also, it was gett5really cold without heat and, I was nearly hit several times as i was also at the bottom of a steep hill when my car decided to stop sliding backwards and stall on me and would not restart. That was the most fearful I have been with this issue and with good reason! I now see several others having similar issues with their same exact car. Why isn't Toyota addressing this?

I have had my 2009 Toyota Corolla since day 1. I seen another post in here that is having the same issue as myself. I have had to replace my battery 3 times all because the “wiring harness” on this vehicle is faulty. Toyota knew about this beforehand. As customers we put our trust and faith in these big corporations to do the right thing when making these vehicles. We, as customers, shouldn’t have to purchase and pay for labor when all while Toyota was aware of the faulty wiring harness. This causes more issues than 1 because it controls everything inside and outside of your car.

My Toyota power door lock actuators continue to fail, even after multiple replacements. The failure mode starts as intermittent operation, often leaving doors unlocked when using the electronic locking system. Eventually the door lock actuator fails to respond at all. The intermittent nature of the failure onset puts consumers at risk for not realizing the system left their car unlocked, providing an opportunity for someone to enter the vehicle and wait in the car for vehicle owner to return or to have things stolen from the vehicle. Based on the repeated failures, the actuator design or manufacturing process is clearly defective. The repeated actuator failures requires the customer to be vigilant for failures and the pay for replacement, several hundreds of dollars each time, out of their own pocket since Toyota refuses to acknowledge an egregious failure rate on their power door lock mechanisms. Cynical observers may note that the failures generate a regular revenue stream for Toyota service departments. Thank you for your time.

FIRE ON DRIVERS SIDE DOOR, SWITCHES PERTAINING TO WINDOWS, CAR WAS MOTION

ALL DASHBOARDS CAME ON AND THE VEHICLE STALLED. ALSO WHEN PRESSING THE BRAKE OR PUTTING ANY LOAD ON THE ELECTRICAL SYSTEM THE VEHICLE STARTS STALLING. IT IS NOT CONSISTENT AND CAN'T BE REPEATED CONSISTENTLY.

SUSPECT FAULTY ECM (ENGINE CONTROL MODULE) AS EVIDENCED BY RECALL ON VEHICLES UP TO 2008. VEHICLE RANDOMLY LOSES POWER, BOTH IN MOTION AT VARIOUS SPEEDS AND AT REST. ALL LIGHTS AND INDICATIONS GO DARK. DASH LIGHTS MAY COME BACK ON MOMENTARILY INCLUDING ALL WARNING INDICATIONS IN DASH, AND ENGINE MAY RESUME RUNNING. ALSO STALLS RANDOMLY UPON STARTING, AS WELL AS RANDOMLY WHEN SWITCHING HEADLIGHTS FROM LOW BEAMS TO HIGH BEAMS. RANDOMLY WILL NOT START EITHER, WITH ONLY ONE VERY DIM DASH INDICATION. BATTERY IS 3 MONTHS OLD AND HAS BEEN LOAD TESTED: IN PERFECT CONDITION. TERMINALS ARE CLEAN WITH SOLID CONNECTIONS. HAS OCCURRED SEVERAL TIMES OVER THE PAST FEW WEEKS.

IN MOTION WITH LIGHTS ON, AND WHEN SWITCHING TO HIGH BEAM LIGHTS SHUT OFF AND VEHICLE WARNING ICONS ON DASH LIGHT UP; LIGHTS COME BACK ON MOMENTARILY.

MY POWER DOORS ARE NOT WORKING AND THE MECHANISM WILL NOT EVEN LOCK OR UNLOCK THE DOORS. SOMETIMES I CAN'T EVEN OPEN THE DOOR TO GET OUT AND IT IS SEVERE HAZARD. I CAN'T EVEN MANUALLY OPEN THEM TO GET IN OR OUT. THE MAIN ACTUATOR IS COMPLETELY BROKEN.

TL* THE CONTACT OWNS A 2009 TOYOTA COROLLA. WHILE ATTEMPTING TO START THE VEHICLE, SEVERAL WARNING INDICATORS ILLUMINATED. THE CONTACT STATED THAT THE VEHICLE IDLED AND DROVE POORLY. UPON FURTHER INVESTIGATION, THE CONTACT NOTICED THAT THE WIRE INSULATION MATERIAL WAS MADE OUT OF A SOY-BASED MATERIAL. THE CONTACT WAS CONCERNED THAT CRITICAL FUNCTIONS COULD HAVE BEEN COMPROMISED. THE VEHICLE WAS TAKEN TO DEL TOYOTA (2945 E LINCOLN HWY, THORNDALE, PA 19372, (610) 383-6200) WHERE IT WAS DIAGNOSED THAT RODENTS CHEWED THROUGH THE TRANSMISSION WIRING HARNESS.

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!

7.5Y OLD COROLLA LE WITH 61,000 MILES OF GENTLE DRIVING/EXCELLENT MAINTENANCE, ALL OF A SUDDEN, THE ALTERNATOR FAILED AND THE CAR STEERING WHEEL IS LOCKED, THROWING ME INTO PANIC. I MANAGED TO PULL INTO A BANK PARKING LOT AT CHASE BANK ON 161 W SPRING CREEK PKWY, PLANO. MY PREVIOUS CAR WAS 1995 COROLLA, HAD SAME EXPERIENCE. I WOULD NEVER FEEL SAFE IN THESE VEHICLES. I FEEL THESE DENSO ALTERNATORS MAY BE DEFECTIVE AT SUCH LOW MILEAGE AND GENTLE USE. ANYONE ELSE HAVE SIMILAR ISSUE WITH DENSO ALTERNATOR [MODEL 104210-5480]?

TL* THE CONTACT OWNS A 2009 TOYOTA COROLLA. THE CONTACT STATED THAT WHILE TRAVELING ON A HILL, THE ALTERNATOR ASSEMBLY WARNING LIGHT ILLUMINATED AND THE VEHICLE STALLED.

I AM THE ORIGINAL OWNER OF A 2009 TOYOTA COROLLA WHICH I PURCHASED NEW FROM A LOCAL TOYOTA DEALERSHIP. I HAVE ALWAYS HAD THEM DO RECOMMENDED SERVICE, ETC. AND HAVE TAKEN GREAT CARE OF THIS VEHICLE. IN JULY 2014 MY CAR WAS MAKING A RATTLING SOUND AND I TOOK IT IN FOR SERVICE. AT THAT TIME IT BARELY TURNED OVER AND STARTED, ALTHOUGH I HAD REPLACED THE BATTERY IN 2013. THE CAR HAD A FAULTY ALTERNATOR AND WHEN THEY WERE DOING SERVICE THEY ALSO DISCOVERED A BROKEN WATER PUMP. THE CAR ONLY HAD APPRX. 27,000 MILES AT THAT TIME. ON 8-9-15 THE CAR BARELY STARTED AND AS I BACKED OUT THE BATTERY LIGHT CAME ON AND I LOST MY POWER STEERING. I HAD TO HAVE THE CAR TOWED TO THE DEALERSHIP AND THE PROBLEM WAS ANOTHER DEFECTIVE ALTERNATOR! THE CAR ONLY HAS LESS THAN 32,000 MILES AND ANOTHER ALTERNATOR. ALTHOUGH THE PART WAS JUST OUT OF WARRANTY, THE DEALERSHIP COVERED THE PART, BUT I HAD TO PAY 132.00 LABOR AND GO WITHOUT A VEHICLE FOR 2 DAYS. MY FAMILY AND I ALWAYS OWN TOYOTAS AND HAVE EXCELLENT SERVICE FROM THE CARS. THIS ONE, NOT SO MUCH! NOW I'M WONDERING WHAT WILL GO NEXT. I THINK THIS WILL BE MY LAST TOYOTA.

MY 2009 TOYOTA COROLLA, WHICH I BOUGHT NEW IN 2009, POWER WINDOW PANEL, CAUGHT FIRE ON DECEMBER 30 WHILE I WAS DRIVING IT AND WHEN I BROUGHT IT TO THE FRANCHISE I PURCHASED IT FROM ON DECEMBER 31, THEY TOLD ME, IT WAS REGULAR WEAR AND TEAR AND THAT MY CAR WAS OLD AND I WOULD HAVE TO PAY FOR IT MYSELF. *TR

AT 89,000 MILES, THE BATTERY LIGHT CAME ON EARLY IN THE DAY BUT I CONTINUED TO DRIVE IT AFTER STOPPING AT TOYOTA WHO CONFIRMED IT WAS A "BATTERY LIGHT." LATER IN THE DAY, WHILE TRAVELING CLOSE TO HOME AT ABOUT 25MPH, ALL THE LIGHTS CAME ON IN THE DASHBOARD AND THE CAR STARTED TO SEIZE UP: STEERING WHEEL BECAME DIFFICULT TO MANEUVER AND I COULD BARELY GET THE CAR OVER TO THE CURB (IT HAPPENED WITHIN MINUTES). THE CAR COMPLETELY SHUT DOWN. IT TURNED OUT TO BE AN ALTERNATOR GONE BAD. FRIGHTENING EXPERIENCE BUT I AM GLAD IT HAPPENED AT 25 MPH AND NOT ON THE FREEWAY EARLIER IN THE DAY, OR IT COULD HAVE CAUSED AN ACCIDENT. IN THE FUTURE, I WILL GET ALL WARNING LIGHTS CHECKED OUT PROMPTLY AND NOT ASSUME THAT A BATTERY SYMBOL MEANS ONLY THE BATTERY IS DYING. PERHAPS TOYOTA NEEDS AN "ALTERNATOR LIGHT" AS WELL, AS THIS IS A SERIOUS SITUATION. *TR
