2020 Toyota Camry Electrical System

On multiple occasions the doors have Locked or Unlocked automatically while driving. This puts my children at risk not knowing if doors will stay locked while driving. The problem has not been looked at a dealer. I doubt they could reproduce it being so random and infrequent. There were not any warning lamps or messages.

Only the driver side door unlocks. Started with rear driver side door. Now only driver side door unlocks with key fob. Replaced battery and had fob program still same issue.

The 12-volt battery has gone totally dead twice. Replaced the battery 2 times. Both batteries were fairly new. I believe there is some sort of drain on the battery that the test doesn't show. at a Toyota dealership, they said I didn't drive the car enough. When the battery failed the last time, I had driven the car over 1000 miles in the previous days before letting the car sit for 2 days. No way should the battery die this quickly.

Battery was replaced 6 months ago due to being old, however, on Sept 19,2024 the car was completely dead after 4 days of no driving. Jumped by AAA and taken to dealer. Dealer reported on Sept 20 no issue with battery and no idea what could be draining th battery. Told me I don’t drive it enough even though I just came back from a high mileage vacation and drove it for over 1 hour each way four days prior and two days before that. Told me I need to run for 30 min every other day even if it is just keep it idle in garage. Prior to this battery change I had no such issue letting it sit for days and not start. There seems to be an issue with this year of Camry that is going unaddressed by Toyota and needs a remedy other than drive your car more often as well as being told to buy a maintainer/charger to keep battery charged as told by the tech. This is a widespread problem that needs to be fixed or made right by the company especially when car is under warranty.

Consistent issues regarding battery draining when car sits over 24 hours. Dealer can not find or resolve the problem.

Car battery is dead . Battery is drained without cause, especially if car is park for 3 days or more. I have battery replaced before but still dies if not driven.

Coolant bypass valve not functioning and needs to be repaired. Car can overheat or cause other electrical issues. Dealer stated this is a frequent issue for a lot of models. Not covered under warranty.

After not driving for a couple days I was unable to start my Toyota Camry. The battery had drained for the 3rd time since buying this car in 2020. Safety - N/A Dealer confirmed issue. Yes the dealership No warning lamps.

The vehicle has a parasitic electrical drain that has lead to my wife being stranded twice.

The contact owns a 2020 Toyota Camry. The contact stated that while starting the vehicle, the front end of the vehicle made abnormal exploding sounds and there was smoke coming from under the hood. The vehicle was towed to the dealer, where it was diagnosed that the battery had exploded, and the battery was replaced. The contact stated that while driving at an undisclosed speed, the message "Pre-collision Warning Malfunction” was intermittently displayed. Additionally, the contact stated that while driving on another occasion, the message "Maintenance Required" and messages indicating the Pre-collision, Anti-Lock and ABS malfunction, and to contact the nearest dealer were displayed. The contact also stated that an alarm persistently sounded. The vehicle was taken to the dealer, where it was determined that the failure was due to rodents damaging electrical wires. The vehicle was taken to an independent mechanic for a second opinion, and the mechanic determined that the failure was caused by the acidic residues that remained in the hood after the battery explosion. The vehicle was taken back to the dealer to be repaired. The vehicle was not yet repaired. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 74,480.

The contact owns a 2020 Toyota Camry. The contact stated while driving approximately 35 MPH, unknown warning lights started flashing on the instrument panel.

The contact stated that moments later the failures ceased, and the vehicle started to operate as intended. The vehicle was later towed to the local dealer who was unable to duplicate the failure. The vehicle was not repaired. Recently the failure reoccurred, and the dealer determined that the failure was caused by a faulty battery. The manufacturer was notified of the failure. The VIN was not available. The failure mileage was 32,000.

I purchased my Toyota Camry 2020 in 2021. I am at 56k miles and my car hasn’t started up without a jump for three weeks now. Car battery and alternator checked in excellent condition but somehow battery always drained. Found out that there was a bulletin back in 2020 on this issue that I was never made aware of so now I’m past 36 and Toyota states I have to pay for the update needed to keep my car running which is ridiculous because had I received this update upon purchase in 2021 this wouldnt have happened. This car is brand new and for them to say I have to pay for this Issue they have neglected to take care of is unfair. There should be a class action suit against Toyota for this.

Battery runs down if vehicle is not driven every few days. I did not drive the car for three days and battery was totally dead when i tried to start car. Some unknown current draw runs the battery down. Depending where a person is this could be a safety matter.

Two instances of parking the 2020 Toyota Camry and electrical system going "dead" within 24-36 hours. Battery drained/unable to enter via FOB/unable to start vehicle. Car maintenance and inspection occurred in November 2, 2022. Testing of battery by Toyota Service Center confirmed battery was not issue and worked as normal. Battery less than two years old. Overall safety was not at risk, as car was parked in garage during both instances (March 2022/November 2022). Problem was not able to be reproduced. No warnings were given prior to either event by warning lamps/messages.

Battery keeps draining with no warning. Has left me stranded multiple times. I have had the battery checked & it is fine. Nothing was left on in the vehicle.

PROBLEMS WITH THE DEAD BATTERY ' DRAINING. I BOUGHT THE CAR IN JULY 2020. IT HAS BEEN 2 TIMES I'VE HAD TO CALL ROADSIDE ASSISTANCE BECAUSE MY CAR WAS COMPLETELY DEAD. FIRST TIME, THEY SAID IT WAS BECAUSE THE CAR WAS PARKED AT THE DEALERSHIP WITH NO USE. SECOND TIME, THEY SAID IT WAS BECAUSE MY CAR HAS LOW MILES SINCE I'VE BOUGHT IT. I WANTED TO BUY A NEW CAR TO NOT GO THROUGH "ISSUES" AND I SHOULD NOT BE FORCED TO DRIVE MY CAR MORE THAN WHAT I NEED TO, NOR I SHOULD HAVE TO BUY A TRICKLE CHARGER THE TECH SERVICE GUY RECOMMENDED ME TO BUY AND FOLLOW HIS INSTRUCTIONS ON HAVING TO DRIVE AT LEAST 30 MINUTES TWICE A WEEK, WHEN I ALREADY DRIVE IT TO WORK EVERYDAY. NOW I AM AFFRAID TO DRIVE MY CAR, WORRIED THAT IT WON'T WORK AT ANY GIVEN MOMENT. WHAT SHOULD YOU EXPECT WHEN THEY TELL YOU "I CANNOT GARANTEE THIS WON'T HAPPEND AGAIN IN 6 OR 7 MONTHS"?. VERY DISAPPOINTED. I THEN, STARTED DOING RESAERCH ON MY OWN ONLINE AND FOUND OUT THAT THERE ARE A LOT OF PEOPLE EXPERIENCING THE SAME PROBLEM.

I HAD PARKED MY CAR IN MY APARTMENT PARKING LOT AND HADN'T DRIVEN FOR TWO DAYS DUE TO INCLEMENT WEATHER (SNOW STORM). ON THE THIRD DAY, UPON APPROACHING MY VEHICLE I OBSERVED THE FOLLOWING: 1. THE CAR WOULDN'T UNLOCK THROUGH MY KEY FOB. HAD TO MANUALLY UNLOCK IT. 2. UPON ENTERING AND PRESSING THE START BUTTON, THE MID WAS FLICKERING WITH ERROR MESSAGES SUCH AS (A) KEY FOB NOT DETECTED (B) EPB DISENGAGED. 3. THE BATTERY SEEMED DEAD, NONE OF THE ELECTRICALS AND ELECTRONIC RESPONDED. I UNDERSTOOD THE BATTERY WAS DEAD (STRANGE FOR A NEW CAR BOUGHT 5 MONTHS AGO). 4. I JUMP STARTED SUCCESSFULLY USING MY OLDER CAR WHICH DOESN'T RUN TOO OFTEN, YET COLD STARTS PRETTY GOOD. NO ACCESSORIES/LIGHTS WERE LEFT ON DURING THE TWO DAYS THE CAR WAS STATIONARY.

CAR BATTERY WON'T HOLD A CHARGE KEEPS GOING DEAD. DEALER CLAIM THEY CAN'T FIND NOTHING WRONG. CAR SIT PARKED, LIKE SOMETHING IS DRAWN POWER WHILE CAR IS OFF.

I PURCHASE A BRAND NEW 2020 TOYOTA CAMRY MARCH 2020. ON JUNE 15, 2020 MY VEHICLE WAS PARKED IN MY DRIVEWAY AND WOULDN'T START AND HAD TO BE TOWED TO THE DEALERSHIP. THE DOORS WOULD NOT LOCK AND MY DASHBOARD DISPLAYED A MALFUNCTIONING SYSTEM PARKING BRAKE DISABLED. MY CAR REMAIN AT THE DEALERSHIP FOR 4 DAYS. ON JUNE 19 I PICKED UP MY VEHICLE. THE TOYOTA TECHNICIAN STATED THE BATTERY WAS GOOD AFTER PERFORMING A BATTERY TEST USING TOYOTA DCA8000 TEST. THE TECHNICIAN PERFORMED AN UPDATE TELEMATICS MODULE I9I-13 DCM TO LATEST FIRMWARE TO SOFTWARE VERSION HIGH AT LG-N010FFB AND SOFTWARE VERSION LOW AT CBC-98 OR CBC-34 AS APPLICABLE DEALER TECHSTREAM DIAGNOSTIC TOOL. OK THIS WAS SUPPOSE TO BE THE FIX TO MY PROBLEM. ON AUG 19 THE SAME ISSUE HAPPENED AGAIN. AGAIN I HAD MY CAR TOWED TO THE SAME DEALERSHIP. AFTER A SERIES OF TEST THEY STATED IT WAS THE BATTERY, SO THEY REPLACED THE BATTERY WITH A NEW BATTERY. I DIDN'T UNDERSTAND HOW IT COULD BE THE BATTERY WHEN THIS IS A BRAND NEW CAR WITH LESS THAN 12,000 MILES ON THE VEHICLE. . ON JAN 25, 2021 MY VEHICLE WAS PARKED IN MY DRIVEWAY AND MY CAR WOULD START. THE RADIO CAME ON , THE LIGHTS WERE WORKING BUT THE CAR WOULDN'T START, THE STEERING WHEEL WOULDN'T MOVE AND THE CAR WOULDN'T GO INTO NEUTRAL. I HAD MY CAR TOWED TO MY DEALERSHIP AGAIN. TECHNICIAN ADVISE THE NEXT DAY HAD PERFORM A DCM RESET AND FIRMWARE UPDATE FOR DRAINING BATTERIES TO THE 2020 CAMRY. THIS VEHICLE HAS NOT PERFORM TO THE STANDARDS I EXPECTED SINCE DAY OF PURCHASE MARCH 2020. STATE OF GEORGIA WILL NOT ALLOW YOU TO SUBMIT A LEMON LAW CLAIM BECAUSE VEHICLE WAS NOT OUT OF COMMISSION FOR 30 DAYS TOTAL. I AM A VERY UPSET CUSTOMER AND WILL CONTINUE TO FILE COMPLAINTS WITH TOYOTA HEADQUARTERS AND POSSIBLY SEEK ME A A CONSUMER ATTORNEY. AS MUCH AS I AM PAYING FOR MY VEHICLE I SHOULDN'T HAVE TO CONTINUE TO WAIT AROUND FOR TOYOTA TO GET THIS PROBLEM CORRECT.

BATTERY DISCHARGES EVERY 7 TO 10 DAYS ITSELF. DEALERSHIP CHECKED SAID EVERYTHING OK. BUT CAN'T TELL WHY BATTERY GOES DEAD AL THE TIME.

PURCHASED MY 2020 TOYOTA CAMRY IN OCTOBER 2020. IN NOVEMBER 23, 2020, I LEFT MY CAR IN THE DRIVEWAY. ON NOVEMBER 25, 2020, I ATTEMPTED TO TURN ON MY CAR, BUT ONLY RECEIVED THE FLICKERING OF LIGHTS INSIDE THE CAR. THE CAR WOULD NEVER START. UPON GETTING OUT OF THE CAR, THE CAR BEEPED 6 TIMES. WHEN I WENT BACK TO CHECK THE CAR FOR ANY CHANGES, NOTHING WOULD COME ON AT ALL. WILL BE CALLING DEALERSHIP AND ROAD SHIP ASSISTANCE AFTER THANKSGIVING.
