There are 13 owner-reported visibility & wipers complaints for the 2020 Toyota Corollain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The wipers are turning on randomly by themselves, even when the control switch is set to the “off” position. This has occurred multiple times and happens without any input or activation from me. The issue appears to be intermittent but persistent, and it raises concerns about a potential electrical or control system malfunction.
Windshield wipers stop mid wipe. This seems to be a common issue with this car. It poses a serious hazard when driving in inclement weather.
The windshield wipers stop in the middle of the windshield at times when set to intermittent. Sometimes they will not shut off when they are turned off. This can be a hazard while you are driving and you never know when it will happen.
While driving with the windshield wipers on during a rain storm , the wipers would stop working suddenly. The Car was taken to dealer and windshield motor was replaced. Without working wipers, it was dangerous to drive.
The windshield wipers seize up. On the intermittent setting, instead of wiping every few seconds they sometimes wipe 3 times in a row and then stop in the middle of the windshield sometimes obstructing my view. They sometimes start back up on their own and sometimes are stuck there until I switch to a higher speed and lower speed for the windshield wipers. It becomes a game of trying to restart them while driving while it's raining. It's dangerous.
Wipers randomly stall mid-cycle when in use, speed settings are inconsistent and sometimes fail to function at all.
The wipers keep stopping during use. I have to switch speeds to get it running again. Very dangerous when raining.
The windshield wiper switch assembly (column stalk/switch) malfunctions intermittently, sending unintended signals that activate the wipers despite the stalk being firmly in the OFF position. The component is still installed in the vehicle and is available for inspection upon request. Suspected part numbers include 84652-06400 or similar variants. How was your safety or the safety of others put at risk? Sudden, unexpected wiper activation (typically 1-2 wipes, occasionally more) while driving creates a serious distraction and safety hazard. It can startle the driver, cause momentary loss of vehicle control or focus (especially at highway speeds or in traffic), and briefly obstruct vision. This risk is heightened during rain, when wipers are needed but behave erratically, or during acceleration/turns where vibration triggers it—potentially leading to accidents. Has the problem been reproduced or confirmed by a dealer or independent service center? No, the Toyota dealership has not reproduced or confirmed it during short test drives, as the issue is highly intermittent and occurs mainly after warmup from extended driving (20+ minutes), on hot days or after parking off for ~1 hour in heat/vibration. Similar cases reported by other 2020 Corolla owners on Reddit (r/COROLLA) and Toyota Nation forums were eventually diagnosed and fixed by replacing the wiper switch due to worn internal contacts/PCB from heat/vibration. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle was brought to a Toyota dealership, but no detailed inspection or repair occurred due to lack of replication. No inspections by police, insurance, Toyota corporate (manufacturer), or others have taken place. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning lamps, messages, dashboard indicators, or prior symptoms
THE WINDSHIELD WASHER FLUID SPRAYS OVER THE CAR ONTO CARS/ROAD BEHIND THE CAR. THE WASHER FLUID ALSO SPRAYS INTO THE CAR OF THE SUNROOF IS OPEN. TOYOTA DEALERSHIP REPORTS THAT IT'S 'OPERATING AS DESIGNED' AND DID NOT FIX THE PROBLEM. THIS IS CONCERNING BECAUSE IT COULD DISTRACT THE DRIVER BEHIND ME WHEN I TRY TO CLEAN THE WINDSHIELD AND THEY COULD RUN INTO MY VEHICLE, POSSIBLE CAUSING A MULTI-CAR CRASH.

WAVY WINDSHIELD.DISORIENTING WHEN IN MOTION. DEALER SAID ALL VEHICLES HAVE THIS. I HAVE CHECK AND ALL DO NOT. THEY SAID IT IS KNOWN BUT NOT A DEFECT. I BELIEVE IT IS POOR LAMINATION AND ALONG WITH A BAD VIEW MAY NOT PROTECT IN AN ACCIDENT. I DON'T BELIEVE IT IS 'NORMAL"
