What component or system failed or malfunctioned, and is it available for inspection upon request? the wireless charging unit/electrical system failed. The unit is still in the vehicle and available for inspection upon request. How was your safety or the safety of others put at risk? while driving with all doors securely closed, the system displays false “door open” error messages and disables the wireless charging function. These false alerts distract the driver and could cause confusion or unsafe reactions. The issue undermines confidence in the reliability of the vehicle’s electrical and safety systems. Has the problem been reproduced or confirmed by a dealer or independent service center? yes. The Toyota dealership confirmed the problem and reported replacing the wireless charging unit, but the defect persists. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? yes. The vehicle has been inspected by the Toyota dealership and reviewed by Toyota customer care. Toyota denied further assistance (case #250811002888, letter dated August 21, 2025). Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? yes. Shortly after purchase, the vehicle displayed false “door open” messages when attempting to use the wireless charger. These warnings cause the system to stop charging and continue to appear despite the dealer’s attempted repair.

2025 Toyota Corolla se just wanted to bring attention to the gauge cluster (when the sun is streaming into the car) you cannot read the gauge cluster. The first picture is when the sun is streaming into the car - very hard to read. 2nd picture is upper left side with partial sun glare. 3rd pic is what it should look like all the time. The glass over the gauge cluster should be made out of some kind of anti glare glass so that the gauges are clearly visible all the time or gauge hood needs to be larger.

I was at a red light and when it turned green, I had the clutch in and was in first gear, but as soon as I barely lifted my foot, the car started moving forward on its own. I almost rolled into the car in front of me. At first, I thought maybe it was just me or the shoes but then I noticed the clutch felt like it was getting stuck while pressed. When I tried changing gears, it made a metal-on-metal scratching noise. When I was coming to a stop, the car wouldn’t slow down properly because the clutch wasn’t responding. I couldn’t press it in, and since there were pedestrians nearby, I had to slow the car down by shifting gears without using the clutch and pedestrians got anxious and mad around me because they had to speed up to the safe side, pulled to the side and checked the pedal, thinking maybe something was in the way, but when I pumped it a few times, it started working again. For a moment. Then at another red light, the clutch pedal went soft and wouldn’t engage again. I couldn’t move the car. Eventually, it turned off, and I managed to get it into first gear and restart it, but the car jumped forward as soon as it started. I kept pressing gas and going, but I couldn’t shift into second gear anymore. Traffic was building up and I barely made it to a safe spot near a crosswalk. It felt unsafe to drive. And had to be tow then I did some bleedings and changed fluids no response. After finally being seing by Toyota and researching; all Toyota Corolla from 2020 and up have this problem the so called clutch master cylinder it breaks so premature my car barely has 41k miles on it. Unacceptable and warranty wont cover it.

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.

Toyota defectively designed and/or manufactured coolant bypass valves ("the defect") that prematurely fail. When the defect manifests, coolant leaks out of the closed-loop coolant system. This adversely impacts the ability of the coolant system to properly regulate the temperature of the engine, and can lead to engine overheating, stalling, increased emissions and catastrophic engine failure. In addition, the leaking coolant can leak into the surrounding engine components, including the electrical system, and damage those components. The leaking coolant can also corrode the sensor on the coolant bypass valve, which causes it to remain stuck in the "open" or "closed" position and thus impedes its ability to properly direct coolant throughout the engine, thereby impeding the ability of the engine to operate within the appropriate parameters. When the defect manifests, it also causes a message to appear on the dashboard over the speedometer, which states: "engine maintenance required" and "visit your dealer. " the message cannot be dismissed or otherwise removed from the dash of the class vehicle by the operator of the class vehicle, and instead must be brought to a dealership or to a mechanic. The message is distracting and obscures a significant portion of the speedometer. Blocks other important, safety-related messages that are intended to display in the same area of the dash occupied by the message. Cars system reads “engine maintenance required” due to coolant bypass valve, car is only at 42,000 (6,000 miles past warranty) was told it’s not covered under powertrain warranty and was charged almost $1000 to get it fixed.

There is a persistent high-pitched noise coming from my vehicle, which has now led to significant physical symptoms including migraines, nausea, dizziness, and increased sensitivity to sound, has made driving a painful and unsafe experience. The problem occurs nonstop if the a/c or heat is on. The noise is high-frequency, sharp, and continuous, and appears to originate from within the dashboard area or hvac components. I went to the dealership multiple times with this complaint and they claim it is normal operation. I did not hear the same issue in the cars they compared mine to, but after Toyota's refusal to address the issue I looked it up and there are other reports [xxx] ). When at the dealership, I am continually faced with dismissive responses from the service departments and technicians, who have failed to address the underlying cause of the sound. This sound creates a serious distraction while driving and has caused physical symptoms including headaches, nausea, ear discomfort, and dizziness. These symptoms impair my ability to concentrate and safely operate the vehicle. On longer drives, the effects intensify, increasing the risk of driver fatigue, disorientation, or even potential loss of control. I believe this presents a significant safety hazard, not only due to the physical impact on the driver, but also because it undermines focus and reaction time, especially in high-traffic or high-speed conditions. This issue should be investigated for potential defects in the hvac design, acoustic insulation, or related components. Please investigate whether this condition is present in other vehicles of the same make/model and consider whether it warrants a safety recall or manufacturer intervention.

I was at an intersection, and the engine suddenly stopped for no apparent reason. This message shows up on dashboard: steering power low. It asked me to put it on park and turn the engine back on. Very dangerous.

I am experiencing persistent and unresolved issues with the infotainment and display system in my Toyota Corolla, primarily involving apple carplay overriding the driver display. Even when I manually disable the setting that allows carplay/navigation to take over the display behind the steering wheel, the system does not retain this setting. After turning the car off and restarting it, the navigation/map interface reappears and overrides the driver display again. This behavior is extremely distracting while driving and interferes with my ability to safely view normal vehicle information. It has created multiple situations where I felt at risk of a collision due to unexpected display changes and distraction. In addition, there are ongoing system malfunctions including: •volume controls becoming unresponsive (the slider does not adjust sound), requiring the system to be restarted to function again. •intermittent failure of the phone connection/charging port, where the device does not connect properly to the system. A prior software update temporarily addressed one issue, but the core problems persist. I have been attempting to resolve this through ardmore Toyota dealership in PA for approximately one year without a meaningful fix or access to a qualified technician. This appears to be a recurring software or system defect that affects driver attention and vehicle operation. I am concerned this creates a significant safety risk for myself and others on the road. No one has taken me seriously even after I’ve gone to several Toyota dealerships over and over and I explained my concerns and they promise that I’ll be on a list of waitlist to be seen by a field tech technician however that has never happened and they are refusing to provide assistance.

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.

Dear better business bureau, I am filing a formal complaint against Toyota motor north America regarding a serious and unresolved safety defect in my 2024 Toyota Corolla le (VIN [xxx]). The vehicle experienced two incidents of sudden unintended acceleration—the second, on [xxx], resulted in a collision. Despite my repeated efforts to resolve the issue, Toyota has failed to respond adequately or provide critical diagnostic data. In both incidents ([xxx] and [xxx]), while stopped at a red light, the vehicle suddenly surged forward despite my foot being on the brake. On [xxx] this caused a collision. My vehicle has remained undrivable since. Toyota conducted a diagnostic inspection on may 29 under case #[xxx]. I’ve repeatedly requested access to the raw data from this inspection to understand the defect, but Toyota has not responded. Emails to the assigned case manager, ms. Cynthia ware, have gone unanswered. When I was directed to reply to a support email, it bounced back as a “do-not-reply” address, redirecting me to a login page which falsely claimed I had no active cases. This created an endless communication loop. Toyota’s lack of transparency and support is unacceptable—especially given the severity of the issue and the fact that the vehicle is still under warranty. I am requesting: immediate release of the raw diagnostic data from the may 29 inspection a prompt resolution, including full repair, replacement, or buyback clear, responsive communication from an authorized representative this is not only a financial burden, but a serious safety risk. I respectfully request bbb’s assistance in securing a resolution and holding Toyota accountable. Thank you for your time.

Dashboard warning: engine maintenance, visit dealer Toyota service center diagnostic found code p268115 - engine coolant bypass hose valve circuit short (recommend replacement of coolant bypass hose) an identical error is addressed with Toyota's customer support program 24te04 covering certain 2020-2021 Corollas (up to mid-January 2021). Reported vehicle's manufacture date is not covered under this program notice.

An engine maintenance required warning popped up. The pop up wasn't going away. My engine sounds louder than usual when turning my a/c on.

Engine coolant bypass valve.

My vehicle was backed into while ì was inside of it in a parking lot. Due to my horn failing. , I was unable to alert the other driver to see me. The clock spring is what failed the first time at 95k they replaced it. I'm now at 147k and it failed again . Now I'm discovering that if it does not work, there's an electrical circuit failure and that the airbag will not deploy if I get in an accident. This is a serious safety issue and I feel Toyota should be responsible for it for the life of the vehicle . A horn should never go out. Especially if it not working will keep my air bag from functioning properly . 850 out of my pocket is way steep. The replacement part lasted half as long as the original part did when I bought the car that to me seems like a faulty part this should be obvious and they should just fix the problem cuz I might have to just consult an attorney should they choose not to. The attached photo shows what happens when you can't beep your horn at somebody who's about to back into your car !!! my car still has not turned on any kind of warning lamp for the airbag or any kind of malfunction light, no warnings on my radio. I have noticed that my lane departure warning seems to work intermittently along with the automatic high beams that like to flash my high beams in people's face for some unapparent reason which also seems like a safety issue. If I had to take my car to an inspection station it would not pass an inspection due to the horn not working ! you cannot take your child to the department of motor vehicles and let them take their drive test if your horn does not work ! which happened to be my case !! very disappointing to say the least especially when you've paid $30,000 for a car.

My 2021 Corolla showed an engine maintenance required message. This message pertains to replacing the engine coolant bypass valve - a common occurrence for the 2019-2023 Corolla/rav4 models. I have seen multiple instances online of complaints of this same issue around the 50k-60k mark of the vehicle. This should be a recall due to how common the problem is. I’m here to add on to that tally of complaints that have already been submitted.

Once I parked my car and turned on the a/c a couple mins later I received a warning message on my car screen saying “ engine maintenance required visit your dealer”. After having my car for 4 years I’ve never received this message till now (04/22/25). I thought it was because I needed an oil change but I was wrong because my oil is good. I checked my car and saw that the issue is the “coolant bypass valve”. I don’t even use my car that much for this to happen. I saw this is a common issue with a Toyota Corolla 2020 but the dealership does not want to fix this issue for free.

I was coming to a stop and the clutch slave master cylinder just sank to the floor and wouldn’t activate the clutch. There were no symptoms of the clutch failing or having trouble changing gears prior to its failure. It was inspected by the Toyota tech and he couldn’t give me a reason for its premature failure.

Subject: vehicle safety complaint — dashboard/windshield reflection severely impairing visibility on 2014 Toyota Corolla (VIN: [xxx] ) to whom it may concern, I am writing to report a serious safety issue with my 2014 Toyota Corolla, VIN [xxx] . Under certain daylight conditions, the dashboard (or a component of it) reflects sharply on the windshield, producing a glare so intense that it significantly impairs my ability to see the road ahead. Vehicle details: make: Toyota model: Corolla year: 2014 VIN: [xxx] approx. Current mileage: [insert mileage] problem description: - at specific times of day — when sun angle, interior lighting, and windshield geometry combine — the dashboard reflection becomes very pronounced. - the reflected dashboard elements (vents, panels, interior contours) appear on the windshield glass and overlap the driver’s forward view. - this glare regularly blocks or obscures pedestrians, other vehicles, road signs, or hazards ahead. - the issue is not cosmetic; it directly reduces visibility and increases risk while driving. - the vehicle remains stock — no aftermarket modifications have been made to dashboard or windshield that could cause this reflection. Impact on safety: - I frequently struggle to see clearly under these lighting conditions, compromising my ability to react properly to traffic, obstacles, or sudden changes — especially when approaching intersections or dealing with glare. - this defect endangers not only me and my passengers, but also other road users: drivers, cyclists, and pedestrians. Request: I request that national highway traffic safety administration (NHTSA) review this issue for the 2014 Toyota Corolla (and possibly other model years) to assess whether dashboard materials, interior design, or windshield geometry create a widespread visibility defect. I am willing to provide additional documentation — such as photographs or videos showing the reflection information redacted pursuant to the freedom of information act (foia), 5 u. S. C.

The horn has failed to work now for the second time. I first had this problem at approximately 97000 right before my warranty was up, and Toyota had to replace the entire horn assembly they said that the wiring got wrapped up behind steering wheel and they weren't sure how . Now it started intermittently working the day I was going to let my daughter take her dmv drive test so she was not able to use my car it was sounding sick when I pressed it. Now it will not work at all . My car currently has 140k on it . Complete safety hazard when someone pulls out of a parking space and you can't alert them to not hit your car! you panic!!!! . This is a safety issue!!!! and I have had no warning lights that came on, nor any messages on my system warning screen on my radio. I've checked all my fuses they are fine. Nobody should have to worry about replacing an 800$ horn assembly every 40k that's ridiculous I have never had a horn failure. I feel this needs to be investigated I may not be the only one with this problem. I think they should be required to fix something of this nature just as they should all air bag and seat belt issues . It should never fail!!!!.

Coolant bypass valve. Code is p2681, part will fail and vehicle will consistently display a engine maintenance required visit your dealer on the mid.

While driving my vehicle southbound on [xxx] in the simpsonville/fountain inn area of south carolina, my vehicle suffered some sort of catastrophic failure while driving and became completely engulfed in flames. The vehicle was a total loss. The vehicle had been serviced a little over a month prior to this incident happening. The fire department took a report for the fire. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was able to distinguish today the car noises my vehicle is making happens when I break. Like a “eeeeek” sound. My mileage is under 8,000, had the car almost a year. Also I notice my wheel stiffens. I’m able to verify it happens when I merge - specifically when the lane dashes end. The wheel somehow gets tight even when driving with both hands. As if the vehicle gets confused. This has happened about 5 times this year but every time it happens- I brace myself for the vehicle to crash since I can’t control the wheel, no matter how strong I try to gain control. The wheel gets too tight to steer. These episodes lasts about 3-4 seconds. I am going to take it to the dealership on April 1, 2025. Also there were no messages on my dashboard when these episodes occurred.

The Toyota Corolla le screen goes blank and does not show any information. When the screen does work, the map malfunctions and shows the vehicle and directions in various bodies of water and displays unsafe routes. The car is available for inspection upon request. You are unable to drive hands free which increases the risk of distracted driving. Map routes to unsafe areas which can make a driver drive into areas that are unsafe to themselves and endanger other motorists and pedestrians. By the Toyota dealership, yes. They stated there was no recall for it and that they could not recreate the issues. No.

My 2019 hatchback clutch failed clutch release bearing and slave cylinder assembly is leaking. Toyota part # 31400-19027.

Odometer on 2005 Corolla s stopped working at 299,999 miles. Will not roll over to 300,000. This has been a topic of discussion on many Toyota vehicle online forums and has been an ongoing issue for many similar makes/years/models. There were no prior warnings/messages related to the odometer not working any longer when it reaches any certain number. Several mechanics I have spoken to, including Toyota service advisors, have told me they are aware of this issue. No inspections have been done. Why would Toyota place an odometer in any of their vehicles that will stop working after reaching any specific number? they have prided themselves as cars that will go many miles. Why would they not disclose this to any Toyota owner? why should the owner be liable for repairs on this issue when we did not install the part? why has no recall been issued over this matter?.
