2021 Toyota Corolla: check engine light

Filed Jun 15, 2026 · Tires · CA

Over the past year and a half I’ve had to deal with unknown reasons for at least 13 tire problems. And one of those problems was a complete blow out on the highway. When I went to get my spare tire and change it there wasn’t anything in the trunks spare compartment. I called the dealership and they said they don’t do that (meaning they don’t provide the car with a spare). I was very confused and stressed. I felt played and wasn’t made to feel confident in this purchase. That not the only thing. The electric system does pretty much whatever it wants. Changes my music, gives advice for things we didn’t ask and the volume is always highering itself and lowering just whenever it chooses. The airbag light has been on most of the time letting me know the passenger airbag isn’t on or working properly. The engine light has been on for at least four months now. I understand Warranty for regular checkups and maintenance but this feels a bit more serious than me making sure I’ve secured my warranty. I have called and taken the vehicle into both Toyota of Visalia and Toyota of Selma where I got financing for the vehicle. Toyota of Visalia wasn’t very much help at all and preceded to talk down to me. Toyota of Selma keeps giving me the run around and telling me different things about my warranty. This car isn’t worth the trouble my credit score goes through to secure it each month just to have something else fail me in it. At this point I’m trying to figure out how I’m going to replace the DC to DC because the car died a week ago and hasn’t turned back on since. And yes I’ve tried jumping the battery already. I’ve only had this car a year and a half. I wasn’t made aware of any issues with it when I drove it home that day. It was a nice ride home but less than a couple months I was already having questions about its performance. I really wish this complaint would even help but I’m just writing to probably waste my own time.

I just had to replace my transmission. 2 days later I have my check engine light, secondary collision, pre collision and parking brake malfunction lights came on. There is a osc recall that could cause these issues, but they’re saying stated my specific vehicle isn’t under a recall

I recently purchased a 2021 Toyota Corolla SE. After a few days the "Engine Maintenance Required - See Dealer" notification appeared. See as it was purchased very recently, I assumed this was the oil maintenance light, and reset it. Later that day, it came back, and I reset it a different method under the assumption I did it wrong. The next day it was back, and that is when I realized it must be something else. So I started doing some research and found lots of other people have had this same issue: 2020-21 Corolla, greater than 30k miles, usually less than 60k, and while the Check Engine Light *DOES NOT TURN ON* the car is throwing an error code: P268115 - Engine Coolant Bypass Valve. Sure enough, I have the codes pulled and I have that code showing up. So I took it to the local Toyota Dealership. They stated that the issue was not a warrantable, so I would likely have to pay out of pocket. After a slight fuss, they agreed to fix it as a "one-time goodwill gesture, performed in the interest of customer satisfaction..." So in the end, they did fix it; I did still have to pay for a diagnostic of the issue which is frustrating, especially since I was dead on in my analysis of the issue. To answer the guideline questions: Engine Coolant Bypass Valve Leaking engine coolant could cause the engine to overheat, which can lead to fires, not exactly ideal. It can also cause electrical shorts, leading to more issues. Yes. Lancaster Toyota confirmed the issue. Yes, Lancaster Toyota confirmed that the part was faulty. They appeared shortly after buying the car. There were no error lights like I'd expect, but there was the constantly appearing "Engine Maintenance Required - See Dealer" message which the Owner's Manual states is simply the 5000 mile Oil Change warning. Hidden behind this message is the error code P268115.

Apparently my car's Engine Coolant Bypass Valve is broken and it's a common case with my car's model that's made after 2020. Seems like it there's a need a recall for such a thing since it's a defective part they knew about since my car was screaming at me for an engine maintenance. However, the check engine wasn't on. I went to Toyota at Elk Grove, CA and knew what the issue was pretty quick and charging me $700 to get it replaced. I feel like it's intentionally being handled poorly so they keep charging me 700 every few years to replace a $80 part. As well my story is very common with other customers of Toyota Cars made after 2020. I wanted to report this since that's potentially harmful to put out a car that could have engine problems easily. Especially it's a fairly newer car. Also, they have yet to replace the part for the known recall on this vehicle.

After hitting 45k miles my engine light turned on and required a coolant bypass valve replacement. This issue has occurred for all Toyota Corolla drivers and rav4 drivers I have came in contact with. This issue should be resolved my car is only 3 years old and should not require pricey engine repairs.

The contact owns a 2021 Toyota Corolla. The contact stated while his granddaughter was driving approximately 20 MPH, the check engine warning light illuminated. Additionally, the Parking Brake and Lane Tracing Assist malfunction indicators were illuminated before the vehicle stalled. The vehicle failed to restart and was later towed to the local dealer who diagnosed the vehicle and determined that the engine control unit software needed to be updated. The vehicle was repaired. The manufacturer was not contacted. The failure mileage was 30,000.

I went in after my vehicle displayed a check engine code after my recent visit to the dealer which included a regular oil change plus multi point inspection. At 51k miles the check engine went on and said immediately to go to the dealer. After paying for the dealer inspection, which was extra money, the issue was the engine coolant bypass valve for my vehicle that failed and leaked. I asked if this was common and the dealer said yes since they've been replacing them. I checked online forums and hundreds of people have had this issue at random miles. This costed me over $900 dollars to repair and could of damaged my cars engine leaving me without a vehicle or cause a safety accident. I paid a hefty bill for a faulty item that should have been recalled since it's quite "common" according to the toyota dealership. I regularly maintain my vehicle with the recommended maintenance and this should have not occurred.

I was driving home from school, and while trying to change lanes on fairly busy road on a hill and my car with a CVT transmission stalled out and a check engine light appeared on my dash with a message reading “drive-start control malfunction”. While trying to limp the car home, the engine killed power three or four times within like a five minute drive up some hilly roads and I constantly had to pull to the side and turn the car off and on just to make it up the next hill. I took it in the same day the issue were happening and they didn’t diagnose the issue until two three week after I had originally brought it in and said it was a CVT issue. A week or two prior to this happening, I was coming down a hill towards a stop light and when I get hit the stop light my car jerked and the “drive-start control malfunction” messages appeared then immediately went away, so I paid it no mind.

My 2021 Toyota Corolla, with 3000 miles and less than a year on it, is repeatedly exhibiting a "check gas cap" warning message followed a day or two later by a "check engine, visit your dealer" warning. This has happened twice. I have returned to the dealer once to have the system reset, after which the same sequence of warning messages recurred. This message wipes out my dashboard display and keeps me from using my cruise control and radar distancing feature. I have not yet determined what other safety features are neutralized by this recurring malfunction. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Got in the car this morning and the check engine light came on. Needed to get to work so started driving. About 5 minutes later car started shuttering and reduced engine power displayed. Had to do 20 MPH all the way to work. Did not make for a good morning. The lane keep assist and other safety features were turned off as well. Not very safe when driving.
