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...

When using built in carplay navigation the gps will start drifting 10-20 feet from the highway into field or other highways causing it to reroute constantly. When phone is disconnected from CarPlay during the gps drifting current location will go back to right location on the phone. We tried connecting different phone to Corolla all had the same issues. My other two cars Don’t have this issue using the phones. Dealers won’t address the issue

Volume of media from certain apps can't be adjusted. The vehicle says that if media is not playing, the volume can't be adjusted. This can cause distraction while driving and increase risk of a crash. Specific application where this is the case: Youtube audio through an Android Auto connection. Yes it is available for inspection. My safety and the safety of others is at risk, because all Toyota models with this infotainment system function the same way. Drivers may choose to become distracted by their mobile device while trying to adjust the media volume, risking a crash. The problem has not been reproduced or confirmed by dealer, however it would be very easy for me to do so. The vehicle has not been inspected by any party outside of the Toyota dealership. When attempting to adjust the volume, the volume level will appear as a numerical value in the infotainment...

Brake booster failure and lost power due to malfunctioned battery . Car could not start and had to be transported by road assistance to dealer for repair. Dealer had to replace Brake Booster as well as replace battery with a new one. Car was purchased brand new in March 2023. Only 10700 miles on it.

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,...

Engine stopped at a red light and I had an indicator saying that the power steering was low and to press the brake to reset. Try to once it happened yesterday two 222/2023

At a stop, the engine shuts off. This is normal. In two instances, the vehicle threw up multiple warning lights (Press Brake Firmly to Restart) and would not start on the release of the brake. The second incident happened on a hill and the vehicle began to roll backwards. The vehicle then needs to be put in park, shut off and restarted. On the restart it moves again. The dealer was called about this, but said they didn't know it was a problem. They cannot replicate. The safety issue is that the car needs to restart to drive again. At a green light, the car is at risk of being hit since it won't be moving, as expected. It is also a problem that when the brake is released and the issue happens the car can roll backward.

I was at a stoplight and the car cut off. Not the normal auto power down feature, there was no power. A message saying press the brake down to restart appeared. Then a message saying steering power low appeared. The check engine light came on. I pressed the break down, and the vehicle did not restart. I put the car in park then restarted it and was able to drive again. But at the very next light, the same thing happened.
