| Wiper problems |
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.
When I use blinker windshield wipers turn on and sometimes when I call or somebody calls my cell phone I can hear them, but they cannot hear me. Does not happen all the time, but I was concerned since there was a recall on certain Toyota Corolla that says a short circuit may develop in the OCS sensor, preventing front passenger air bag from deploying and my son who is a mechanic said both of these could be a problem with the wiring in the column and I thought it may be connected to the same recall as the air bags? the wipers coming on is happening more often these days and that is why I mentioned it to my son who is a mechanic. He will not touch it since it is still under my extended protection but he is concerned about it getting worse since the blinker is attached to the column. As far as using not being heard by callers or when I call I am concerned if I need to call in an emergency the ones I call cannot hear me. As far as when this started I do not remember but I know it's been at least 6 months if not longer, it just seems to be doing it more often lately.
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.
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.
Dealer stated that there was a chemical buildup on the inside of the windshield that could affect the safety camera sensor (they claimed it was probably windex). Dealership claimed that the camera enclosure is not sealed and particulate may enter the enclosure. Said the problem is not covered under warranty. What happens is someone is a smoker or lives on a dirt road? does Toyota expect particulate in the enclosure to be acceptable? this may impact the performance of the safety systems, especially if there is sun glare. I bought the car in October 2019.
I was driving down the road and my driver window blew up. Yes, it blew up into a million pieces all over me and hit my face. Nothing had hit my windshield. None of my windows were down. I thought I was getting shot at, the noise of it blowing terrified me! I took my car to Toyota and said there was nothing they could do!! my warranty won't even cover it! it's 700 dollars to fix it. I know this was not my fault and nothing hit my window it would have not exploded if that was the case.
2020 model/4-months old: a stress fracture of the windshield occurred suddenly for no apparent reason. Upon inspection the fracture started at the point of installation under the hood with no other obvious signs of damage or impact. The fracture starts at the edge of the glass and runs up to eye-level, then runs across the windshield.
The drivers side head light has a v shape "void" in its pattern and makes the car unsafe to drive at night. The passenger side does not exhibit this same pattern, so when negotiating a left hand curve, the void is very noticeable and makes seeing up ahead in the distance very difficult (not possible). This happens to fall in the area of what I would call my "look ahead distance" and as such makes the car unsafe to drive at night. This "void" is not present when the head lights are put on "high", so I feel it is a led light bulb issue more than anything else. . . But the servicing dealer refuses to fix this problem citing a similar 2020 Corolla displays the same pattern. They pulled another car into the shop and displayed it along with mine against a wall. While I agree the patterns on the wall looked similar, this was not a good test because you need to see what pattern of light is cast down range at night. Please see attached picture. If all newer model Corolla se exhibit this light pattern, than the vehicles need to be recalled and fixed along with mine.
Tl-the contact owns a 2020 Toyota Corolla. While driving 60 mph the windshield cracked without warning or impact. Additionally while vehicle was parked the windshield cracked, the vehicle was taken to an independent mechanic where informed the windshield needed to be replaced. The contact called nalley Toyota union city 4115 jonesboro rd, union city, GA 30291 (770) 284-8361 but was not diagnosed or repaired. The manufacturer was contacted but did not assist. The failure mileage was 20, and 10,000. The VIN was not available . Ap.
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".
