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!!!!.

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.

Manual driving shaft slips out of 6th gear while driving affecting the driving speed and increasing rpms.

Front is very low. Right side is tilted without anyone inside. Very unusual tire wear on inside edges of both front tires. Immediately after starting the engine the front ricked side took side and made loud noises.

When idling my car makes a rattling sound and vibrates and oil smells like fuel only got 12k on it when I bought it which I just bought it not even a month ago used.

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?.

2017 Toyota Corolla se was bought new. Original blizzard pearl paint under recall program. Paint has peeled in "spots" all over car. Toyota fixed "spots" in August 2021, then again in June 2024. Since then, more spots have appeared. Toyota in mt. Vernon, IL refuses to fix "spots" anymore since Nov 2024. Toyota has paint peeling recall program for 2009-2018 Toyota Corolla which was extended up to 14 years to address the peeling issue which was attributed to a manufacturing defect. The car should have been repainted from the beginning. Why would they think the paint would stop peeling after fixing spots? I have contacted Toyota customer experience center many times. They said they go by what NHTSA tells them. They gave me your number and I was instructed to fill this form out. Any help would be greatly appreciated. I have attached a pic of peeling above license plate. There are more pics of peeling which I can provide if need be. Also, there is a pic of the Toyota paint peeling recall program. Mileage is 67,000. Thank you for your time.

Engine maintenance required notification came on. Car is only 3 years old. Dealership stated that the coolant bypass valve needs to be replaced and it could potentially cause a fire. Service professional at the dealership stated that this is a common issue and most of the time Toyota warranty doesn’t want to repair it, also said that it should be recalled. I have also seen hundreds of people complain about this on rav4 forums.

We were driving on [xxx] near norcross, GA about 200 ft from exit [xxx] at a constant speed of around 70 mph, when suddenly the vehicle displayed 'system malfunction' and started veering on its own and the brakes wouldn't work. It kept veering to the right and crashed into a vehicle 2 lanes away and rebounded back to the original lane and came to a halt with a message displayed 'shifting to p'. The malfunction and loss of control, along with the brakes not functioning those few seconds/minutes put our lives and others' on the road at risk. The vehicle is available for inspection. The vehicle was towed on the day of the accident and then taken into a Toyota dealership and is currently there. The vehicle has not yet been repaired. Toyota sent a third-party inspector to gather data from the vehicle but that turned out to be merely the crash data up to 5 seconds prior by which time the malfunction had already occurred and the vehicle speed was down from 70mph to 31mph. The incident occurred on Thursday, [xxx]. We do not feel safe driving that vehicle again. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I have a 2020 Toyota Corolla. "engine maintenance required; visit your dealer" came on the display after I brought my car to the dealership. I returned to the dealership and was told it was $250 to diagnose the problem. I waited a month later and brought my car back for an 80,000 inspection at the longo Toyota in prosper texas. They diagnosed the problem this time and said they would have to replace the coolant bypass valve and hose for ~$800 plus labor costs. The risk of not repairing these parts is possible engine failure or fire. I've seen many other discussion forums where people are experiencing the same problem with rav4, Corolla, and camry models 2020-2023. These parts are not covered under warranty and would have to pay out of pocket for the repairs. Toyota should issue a recall since many people are reporting these same issues, creating out-of-pocket costs for the repairs for >$800.

White paint peeling off, it looks like Toyota haven’t painted this car with primer before the base coat.

Toyota Corolla 2020 engine coolant flow control valve.

On10/19/2024, the driver was driving down a road that was coming down from a slope and the road curves to the left. As the driver was braking to decrease the speed down to 30mph or below (she was going around 35mph from what she remembers) and turning the steering wheel left, all the curtain air bags deployed, the seatbelt locked and she was unable to turn the steering wheel. She couldn't see due to the airbags and the seatbelt locking her back so when she felt/heard scraping on the right she feared she was going to crash into trees so she yanked as hard as possible to the left and the car then stopped. She remembers that the screen flashed something like an sos but then it faded. Bystanders helped her out of the car as she was still in the car (she was very shaken) and they tried to put the car in neutral as it was blocking the road to push it but they were unsuccessful as the wheels had locked. The police and a tow truck was called by a bystander. Other than a small scrape on the right fender of the bumper, there was no damage to the car. Nothing was in the road. The bystanders asked her if she had a stroke or some medical issue since there was no collision, no damage notable on the car and the car just stopped on the road. Inside all the curtain bags are deployed. The police officer and the tow truck driver thought that the sensor for rolling might have gotten triggered but there was nothing that they could see that would have triggered it. Toyota was contacted and the insurance company was unsure if this was considered a collision. Toyota wanted to investigate the car themselves and we signed a letter giving them permission to download data and information from the car. We were told they would be sending someone to physically look at the car.

-coolant bypass valve -it risked my safety by possibly destroying my perfectly good car -yes my Toyota dealership confirmed the faulty coolant bypass (which many people have had this exact issue with these Toyota models) -no -yes about a week before it was serviced.

When using built in carplay navigation the gps will start drifting 10-20 feet from the highway into field or other highways causing it to reroute constantly. When phone is disconnected from carplay during the gps drifting current location will go back to right location on the phone. We tried connecting different phone to Corolla all had the same issues. My other two cars don’t have this issue using the phones. Dealers won’t address the issue.

The check engine light came so I took it to Toyota dealership. I paid 300$ to get a diagnostic and they said it was my coolant bypass valve and it was 900$ to fix. Warranty doesn’t cover this even tho my car qualifies for the coverages. It’s super frustrating since I bought this car brand new and im having multiple expensive problems. I need to replace the transmission, brake actuator, oil replacement pan and I had to replace a brand new battery because it exploded after only using for less than a year.

I was sitting idle in my car. The two cars crashing icon came on even though I was in the parking lot doing nothing. There was also issues with the other indications where I would use the back arrow on my steering wheel to clear the issue and it would not clear. Seems unsafe and scary.

My car has warning light of the engine maintenance required and I had to change my electrical water pump when I first got the car and the dealership doesn’t cover the issues.

Coolant bypass valve. Becoming persistent in several models of Toyota 2019-2021. Dealerships claim it’s not covered under powertrain warranty because it’s part of the coolant system. Should be covered and customer should be compensated or reimbursed.

Engine coolant bypass valve malfunctioned at 34xxx miles, causing “engine maintenance required” this could cause the engine to get too hot or not hot enough and affect the internal components of the engine. After speaking to others with the same model and even other models, it seems to be a ongoing issue for many people.

At 61,000 miles I got an engine maintenance required light. After doing research on the internet, I see that many people with the Corolla similar years have had this issue. It is an engine coolant bypass valve.
