2021 Toyota Corolla

Notification spontaneously received as Engine Maintenance Required; Visit Your Dealer. Service appointment immediately scheduled for Toyota of Plano for the following day. My service advisor recommended replacing the coolant bypass valve, which amounted to a total bill of $745. My agent informed me of CSP 24TE04, however my service advisor didn’t acknowledge any eligibility of VIN pertaining to it. Toyota Brand Engagement Center also did not report any eligibility of my VIN number for secondary coverage reimbursement despite it meeting the criteria exactly.

This Toyota Corolla hatchback is experiencing an issue where it is constantly giving an “ENGINE MAINTENANCE REQUIRED” light and when scanned, it says “coolant bypass valve malfunction”. There is already a recall for many Toyota Corolla Sedans experiencing this issue of this bypass valve being defective, but because this is a hatchback, it is not part of the recall when it should be. There is already a recall for vehicles affected with this issue: T-SB-0112-24

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.

Within a week of buying my vehicle in May of 2021 I went to Clearwater Toyota where I bought the vehicle from and complaining about the three seat belts in the back malfunctioning. When nobody is sitting in the backseat they sound off as if somebody is sitting there. I know that there is a recall on the front seat belt sensor doing this same issue for the Toyota Corollas but everyone I have spoken to that owns a 2021 Toyota Corolla complains about the back seats doing it as well the sensors misfire or sound off every hour as I'm driving at least once an hour. As an Uber Lyft driver I am concerned about my passengers in the backseat wearing the seat belts and the seat belt malfunctioning due to the sensors malfunctioning since I bought the vehicle in May of 2021. Any of the above questions I would have to stay unknown.
