I got a message that the engine needs maintenance and I should go to the dealership and have the coolant bypass valve repaired. I see there's a lawsuit against Toyota for a manufacturing defect in that component on 2019-2023 Corollas. I'd like to know if I'll get a refund.

Multiple malfunctions causing the engine to misfire and eventually seize completely. Toyota never found out the issue but the engine failed. The suspect poor build quality. The engine, brake collision system, fuel pump all went out. Car was rough idling for about two weeks before the engine completely failed. Toyota has lemoned it.

To start, on [XXX], I was going through an intersection on a country road and my automatic emergency braking engaged for no reason. My car stopped despite no other vehicle or object being in my way or anywhere close to me. I found it really weird but did not think much about after the fact. I have also heard a rattling noise under my hood since [XXX] and have reported this to Toyota and tried to have it fixed multiple times (and showed them videos) but they were never able to duplicate the noise so it has not been remedied. On [XXX] I was traveling on a highway during rush hour and the traffic in front of me came to a sudden stop. I braked as hard as I could; my automatic emergency braking did not engage and I rear ended the car in front of me (minimal damage to that car). We both immediately pulled partway onto the narrow left berm (we had both been in the left lane to get onto another highway). My car then turned off by itself and gave me an engine warning (I believe low engine oil- I had just had it serviced 3 days prior). The other car owner and I exchanged information quickly and decided to drive away because we were blocking rush hour traffic and it was dangerous. However, my car would not start back up. I called 911 and they came to use their vehicle to push me to the right side of the highway onto an exit where I was no longer blocking traffic. During the wait, I felt like I was going to die with traffic honking and swerving to avoid me. When the police officer was moving my car, the parking brake engaged when I put the car in neutral and would not turn off, so the smell of burning rubber was strong since the tires would not roll. Once the tow truck driver arrived he was able to use jumper cables to disengage the parking brake but the car still would not start. There were no prior warning lights. The car not starting was confirmed by the dealer- they are holding off doing maintenance to have an engineer check out the car and figure out what happened.

Fuel Injector failed, causing the engine to run extremely rich, misfire, and cause severe drivability issues. Issue occurred just outside vehicle base warranty. Problem was verified and confirmed by vehicle dealership. MIL was illuminated when drivability issue and malfunction started.

Intermittently and without warning for the past few months the vehicle will at times fail to accelerate properly when pulling out in heavy traffic. The RPMs go past 5000 RPMs and the vehicle barely moves. When I let off the gas and reapply gas the vehicle will go. Vehicle also jerks and hesitates at speeds between 0 -. 30 mph. Disengaging the vehicles traction control helps to alleviate issue. Vehicle and issue will be presented to my Toyota dealer.

Two weeks and three days after picking up my 2023 Corolla Cross from the dealership, I was in stop and go traffic on a busy road. I came to a stop at a red light and my car started making a continuous beeping noise. The display alternated between "Engine Stopped Steering Power Low" and "Engine Stopped Press Brake Firmly to Restart." I pressed the brake VERY firmly multiple times, with no effect. When the light turned green, I tried to move my car to the side of the road, but it did not move. The cars behind me -- including the semi truck directly behind me -- started cutting into traffic in an attempt to get around. I finally put it in park and tried to turn it off, which finally turned the engine back on. (I only had to press the start/stop button once.) Once the engine came on, the car worked normally. The dealership has not been able to reproduce the problem, but an internet search shows that this is not an isolated incident.
