2020 Toyota Corolla Complaint Log

I purchased my vehicle new in 2020. I am currently at 74,000 miles and noticed my engine maintenance required light come on although I received an oil change service two days prior. It’s a different message from the routine maintenance. I got it checked out at Toyota today and the “engine coolant bypass valve” needed to be replaced. When I looked into it I noticed the 2020 Camry and 2020 rav 4 were recalled for the issue and repaired for free. However my model Toyota Corolla was not recalled and I had to pay $700.82 to get it replaced at Toyota today.

Engine Coolant Bypass Valve replacement , Toyota is charging me 888 dollars for repair.

I own 2020 corolla le. It has 50k miles. There is a message that keeps coming up in the infotainment screen and hinders the navigation information especially when i am looking for directions and evey second counts and not being able to act when the exit appearscan cause an accident. The message is caused by a dcm failure. Toyota should never allow a message like that pop up every time on the navigation screen. It keeps saying “ device connected not supported “ every few seconds.

Had my car (Toyota Corolla 2020 SE) give a “engine maintenance required, take to a dealer” error message on my digital dashboard. No error codes from any maintenance device but apparently only the Toyota dealership can find this in the software using their computers to find it somewhere deep in there… The problem is the upper engine coolant bypass valve. This is costing me almost $1000 including the $80+ in diagnostics that ONLY the Toyota dealership can see and find out. Apparently this is a very common occurrence with the 4 cylinder corollas and RAV4s.

After bringing my vehicle in for its oil change and tire rotation, a warning message showed up from my car saying "Engine Maintenance Required".

After I had brought a my car to the dealer for its oil change and tire rotation, a warning message came from my car saying "Engine Maintenance Required".

Wipers randomly stall mid-cycle when in use, speed settings are inconsistent and sometimes fail to function at all.

Coolant bypass valve leaks through wiring and damages itself.

The fuel gauge suddenly malfunctioned giving a false reading of the amount of fuel remaining in the tank. A technician said that the problem seems to be with the sending unit in the tank. I use top tier gas and the car has only about 29,800 miles. The fuel gauge continues to malfunction and could be a generic design flaw. Safety could be put at risk if the vehicle ran out of fuel while driving in traffic. There were no warning lights, messages or other symptoms of the problem prior to the failure.

Electrical issue on vehicle says that vehicles safety features are unavailable and all the light indications on the dash are lit up. It was taken to the dealership several times but the issue still hasn’t been resolved.

“Engine Maintenance Required Visit Dealer” keeps popping up despite engine being fine. Another scan by my mechanic determined that the cooling bypass valve is having an issue/keeps getting stuck and triggering the maintenance alert to keep going off.

I discovered that my 2020 Toyota Corolla SE has a Coolant Valve Bypass malfunction coded "p2688115". I have also discovered this a prevalent issue after you hit 70,000 miles. There are forums all over the internet with complaints about the same issue as mine. I did some research and found no recalls. With this being such a common issue for no reason, faulty equipment. The car has been inspected by a Toyota dealer in Bradenton, FL because we had thought the service vehicle message was for a tire rotation. They scanned the vehicle and discovered the fault code "p2688115" after trying to reset it numerous times. The senior tech was the one who scanned it. He knew the exact reason why it was not clearing before scanning the vehicle. He only scanned it to solidify his hypothesis. I then spoke to the service team, they wanted me to bring it in for a diagnosis that would cost $85.00 if my warranty did not cover it. The cost of the part was estimated at around $150.00 plus labor and taxes. It was over a $400.00 repair. For a repair as such, this needs to be recalled. The warning message never went away, if you tried to clear it to view the screen you had about three seconds before it came back on. It is a major safety risk for those who wear glasses and drive at night. I use the screen to keep myself safe and maintain my driving speed. This warning message came on around 70,000. Some so many other individuals have experienced and complained about the same problem. This needs to be escalated. I am not allowed to utilize the safety features my car has to offer. Please take action and commence an investigation.

The engine Coolant Valve is leaking coolant, in ordering a new part to replace so yes it’ll be available for inspection. My car Could overheat leaving me or my riders stranded wherever it is that the car stops.

The coolant bypass valve in some Toyota models has been malfunctioning recently and has become a common issue. Dealer confirmed that this was the issue per attached diagnostic report/invoice copy. Costs were >$800 to repair the issue for a <$100 part and 30 minutes of labor. The "Engine Maintenance Required" warning was visible in the display. Unsure as to the short or long-term effects of this malfunctioning part, but as it's related to the cooling system of the vehicle, it may trigger other more serious issues.

There is a thing that’s happening to a lot of Corollas and I think RAV4 and some cram it’s called engine maintenance required and a lot of mechanics don’t know what that means so you have to take it to the dealership to get it fixed and it’s like a $900 fix and it’s been happening to a lot of vehicles around 35,000 miles. It’s called the coolant bypass valve. There is hundreds of YouTube videos about it and people complaining about it on forums.

In the past week at 30,700 miles, my 2020 Toyota Corolla "Engine Maintenance light; see dealer" service light appeared on the dash. Through talking with a Toyota dealer, they are aware of this issue with Corollas, Camrys, and Rav4's. It is an engine coolant bypass valve, and appears to be faulty in many vehicles according to youtube videos, google, and Toyota service. Perhaps this needs to be a recall? Also, the dealer wants almost $800 to repair even though many people do it on youtube in under an hour. Parts are less than $200, and 1.5 hours of labor do not add up to $800.

My car, a 2020 Toyota Corolla Hybrid, impacted an abandoned motorcycle on the dark road at full speed; however, none of the airbags deployed.

Around 40k miles I received an Engine Maintenance Required warning. After some research Engine Maintenance and Engine Service Required are two very different indicators. I received and P2681 code meaning the electrical coolant bypass valve had failed unfortunately one can’t tell if it’s stuck shut or open this could lead to one’s care over heating and or damaging one’s engine. After some research I’ve come to find out most 2020-2024 corollas have been having this issue tends to happen about 30-50k miles

Engine maintenance light came on and found out I had replace coolant bypass valve. Apparently this is an issue many 2020 corollas and RAV4 have issues with and need replacement. There’s no reason or rhyme as to why it becomes faulty but should be recalled as many people have the same issue and dealership are aware of this issue.

I had to replace all four tires before reaching 40k miles. Brakes needed to be fully replaced with only two years of driving it. AND Engine Maintenance Light on for an issue with the coolant bypass valve, not covered under warranty. This is causing issues with the engine, when driving even at 25 miles per hour or at 65 the car sounds like its dragging or forcing itself, the wheel shake & car feels unbalanced even with a tire alignment. Overall i give the car a 2.5 out 5 star in performance. The body of the car is so fragile and made by very cheap materials. Spending a fortune on this vehicle and it hasnt even reached 60k miles yet.

Just bought a used 20 Corolla SE and put less then 500 miles on it and got a "maintenance required return to dealer" notification on the dash and a warning message in my information screen via infotainment system. Dealer said they got nothing via a scan. The issue is the Coolant Bypass Valve. I reset the light on the dash and restarted my car with air off and it did not come back on. The second you turn on the air (the A/C in particular) the light immediately popped back on along with a new warning message. I've looked around and there's literally THOUSANDS of people reporting the same issue all on vehicles between 15k and 100k miles. The dealers also charge at least $600-$1100 to remedy this all too common issue as they will tell you it is not covered under warranty. I'm unsure of what promised damage to the vehicle could be but I know for a fact it's not nothing. Everyone is dumbstruck with how many people have this issue and there is still no Recall on this clearly terribly made Coolant Bypass Valve. It seems to apply of us that this is just a cash grab for Toyota

As a driver I was involved in frontal collision with my Toyota Corolla LE 2020 properly serviced. ([XXX]) . Air bags were deployed followed by smoky air that made me difficult to breathe. I opened the windows, but I could not open the door to get out; it was locked. A passer -by could not open the door from the outside either. He told me to move gear shift to P; I did that and he was able to open the door and I got out. There was on loud automatic message informing about collision…. Certain safety steps must be automatically activated after collision. I am very surprise to experience that the driver’s door could not be opened after collision from inside or outside. I had to move gear shift from D to P myself for the door to be opened. I could not breathe properly inside the car even with open windows with air bags deployed. The door should be automatically unlocked after the collision. Driver may be unconscious, the car is in the fire or may be nobody to help the driver.

Issue with unlocked driver's door after the collision reported on 6/25/23 # 11528724 Additional concern: After the accident, my car engine was not turned off automatically; even after automatic speaker announced collision and that 911 was informed. After I got out of the car ( # 1152874) I was standing by the car, drivers door I left opened and at one point I realized that my car was still running ( Gear shift was left in P). I manually switched off the car and I removed the key from ignition.

On three occasions this car was parked in an attached garage and remained running when parked resulting in potential CO exposure. This is a known hazard which NHTSA is aware of in cars with keyless start system in hybrid vehicles. Toyota is well aware of this issue (first acknowledged death in 2016 was in a Toyota Avalon) and was supposed to equip 2020 models with auto shutoff [XXX] I thought my 2020 Hybrid Corolla had this feature when purchased, but it does not. Toyota has not responded to multiple requests to retrofit my vehicle. This is a serious safety issue with many CO deaths reported. Its my understanding this will be required soon of new vehicles but its important that all existing hybrid vehicles be required to be retrofitted with auto shutoff to prevent continuing deaths.

I have a manufacturer defect on my car. The piece of the car's body which goes around the tire and connects to the bumper does not connect right because there is not connector on the bottom of this piece, like there is on the rest of this piece. It often comes lose and it separates, which is very scary when I get out of my car and see that I have a piece of my cars' body separated from the body of the car. I'm scared when I take the freeway or bit a bump on the road. Please help me with this problem.
