2019 Toyota Corolla fuel/propulsion system problems

“Error message that said 'drive start control malfunction. Took 6 mos and numerous attempts to resolve. Replaced numerous parts including the fuel pump because the plastic it's made out of was just disintegrating and and cracking. This has cost thousands of dollars in parts and labor. Also getting a msg on info screen 'connected device not supported' now. Apparently toyota did an update and there was a bug in the program yet I have to pay to fix their error to the dcm.”

“I had recalls “repaired”, but my airbags do not work and Bob Howard Toyota told me that they work and that they only check the sensor to make sure the sensor works. My fuel pump was was supposedly replaced but I still experience issues such as stuttering, slight stalling, engine is working harder to produce normal speeds, fuel economy has depleted and I’m loosing 194 mpg after each fuel up. There are no lights on, but I have a code reader that pulls in two issues. I reported to Toyota’s customer service and because they put in the system everything is okay they were unable to do anything.”

“I have a 2019 Toyota Corolla Hatchback. The problems started on July 21st, 2025. While driving my 2019 Toyota Corolla Hatchback, I noted white exhaust smoke, even after the engine was warm. One week prior, I had filled the coolant reservoir, but when I checked it, the coolant was almost gone again. There were no visible leaks or puddles under the car. I refilled the coolant, but within days the car began shaking severely upon startup and emitted a coolant-burning smell. 5 minutes after, multiple warning lights illuminated on the dashboard simultaneously. I replaced the car battery, and the warnings disappeared. However, while merging onto the freeway, the same warning lights came back, the car lost power, and I could not accelerate above ~25 mph. If this occurred in heavy traffic, it could lead to a serious collision. I exited the freeway and had the car towed. DTCs from the independent mechanic and the Toyota dealer included: P11ED00 P030085 P030027 P030200 (Cylinder 2 misfire) C142571 (Stop light relay actuator stuck) U1117 B2284 B15AD The Toyota dealer identified a “Port Injector #2 malfunction” and recommended replacing all four injectors (~$2,000) but…”

“While driving my 2019 Toyota Corolla Hatchback XSE, I lost almost all power to my accelerator and a check engine light appeared on my dash. I came to a stop and stalled the vehicle, once it stalled I turned the engine back on and shifted into reverse a felt and heard a loud clunk noise coming from right under my car and its not only shifting into reverse is the loud noise active but its also shifting into drive from reverse. I scanned my vehicle with a aftermarket scan tool and got 2 exact same codes for "Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance/Stuck Off" and then two more codes for "Torque Converter Clutch Pressure Control Solenoid Control Actuator Stuck On". My torque converter in my CTV transmission failed. I was not at a risk of putting other people or myself in danger but if would have if i was moving faster at the time this happened. I have done my research on the recalls that are active on this vehicle and on the Toyota OEM TIS website there is only 1 recall that was taken care of in 2021 for the fuel pump and then there is a Warranty Enhancement Program for the Flow Shut-off Valve Coolant Leak. I did not find…”

“My vehicle has a production date that falls within an existing safety recall J07 but Toyota is denying coverage. The cvt is making a grinding noise consistent with the torque converter issue described in the recall and my door has a stamp with being produced in 10/2018 when this recall was in effect. However they are denying coverage.”

“2 years ago, I took my vehicle to the dealership that I bought it from, because I was given notice that there was a recall to the fuel injector system, and my scheduled maintenance was due. The dealership performed the maintenance and fixed the recall, and I drove the car home. The very next day I started the car and noticed that it took 2 key turns to start and didn't think too much about it. Since then, I've put 5000 more miles on the car so the odometer now says 23000 miles. Today I take my vehicle in for maintenance because I want to resolve the 2 key turn issue, and now the dealership says that my fuel injector is broken and I need to pay for the part and labor to replace. I don't understand how the fuel injector being physically damaged is something that I as the customer could have done in 5000 miles, unless the dealer made a mistake when fixing the recall.”
