1. First problem I had with my 2020 Toyota Corolla hatchback safety recall 20ta07 (backup lampsmay become inoperative) - 10. 29. 2020 2. Second problem was with the software draining the battery way too rapidly, which made me unable to start my car. I had to have a tow truck come by and he was able to recharge the battery (he knew to do that with my car instead of towing it away, because he was seeing this type of issue with this type of car a lot). I took it to my local Toyota dealership and had them inspect it. They told me that they need to update the software of the vehicle and that I should not be having this problem again after. *el1934 firmware update (5. 21. 2021)* 3. Third problem I had was with the temperature gauge. The needle pointer in the dash did not go up and stay in the middle between c & h. It stayed closer to c (cold). It took longer than it should have to heat up the interior of the car when I turn the heat on in the morning. I took it to my local Toyota dealership and after they inspected this issue, they told me that they needed to replace the thermostat unit. *ma001 thermostat assembly* (3. 19. 22) 4. Fourth problem is with the transmission. I felt jerking motions from the car when accelerating and when braking-coming to a stop. **26312 car jerking upon acceleration /found trnsmission code /need new trans assy upon inspection and heatlh chfck found code p07457f and po7757f solenoid a b both stuck off /rest memory /no changed /found need new trans mission assy /remove and replace tranmission assy and perform reset and initialization/perform hydrulic and electrical test /no problem found /problem at the transmission itself car jecking upon acceleration** transmission, automatic - replace* (12. 10. 2022) I found out online that the transmission problem was known for 2018-2020 Corolla hatchbacks, but Toyota did not replace it immediately. There should be a general recall for the transmissions for these vehicles ASAP!.
