2024 Toyota Corolla

The system that is problematic for this vehicle is the Pre Collision System (PCS). This system is way too sensitive even on the lowest sensitivity setting, and I have experienced the car braking in error on multiple occasions when driving up or down a windy road. When I approach a bend in the road and there is a car parked on the side of the street, my Corolla will think that I am about to collide with the parked vehicle and make a loud beeping noise and automatically hit the brakes. This has frightened me on a number of occasions, and I am concerned that one day the car will brake in error while there is another vehicle behind me, resulting in a read-end collision. The only consistent method of avoiding this is to drive past the median in the road when approaching bends, which I very much dislike doing, as driving in the middle of the road has its own obvious risks. I have tried contacting the dealership about this, and was told to contact the service department. The service department was no help, saying that they aren't able to do anything about it and that I could try lowering the sensitivity of the PCS, which I had already done. This wouldn't be such a huge issue if there was a way to permanently turn it off. The process for turning it off takes about a minute, as it requires navigating a menu and finding the PCS option to turn off. Unfortunately, the PCS automatically reactivates every time the car is turned off and on again, and even if I use the shortcut method of holding the lane assist button for several seconds to disable the PCS, the car's screen will constantly flash, telling me that the PCS is turned off and annoying the driver to turn it back on. I know that Toyota does not have this issue with their PCS systems on their other vehicles, as I have driven a 2019 Camry before and the PCS system never went off when I drove on the same road, which led me to believe that the system on this 2024 Corolla is somehow defective.

Adaptive Cruise Control (ACC) is unstable in detecting the front car, not only in light rainy conditions but also in heavy rainy conditions. The ACC fails to detect sedans and small SUVs but can detect larger vehicles such as pickup trucks and full-size SUVs. The car does not provide any warning sound or signal to the driver when failing to detect. This poses a significant safety risk as the driver may not be aware that the system selectively detects the front car in both light and heavy rainy conditions. The driver had barely avoided the accident.

On 11/29/23 after 11:30pm, I was in the process of clearing an exit and at the tail end of the exit it felt like the car was "correcting" itself and I was unable to stay turning right. The steering wheel felt locked and I was unable to control the car. The car impacted the guardrail and I was able to regain control after the initial impact. -This is a BRAND NEW car with less than 100 miles at the time of the accident. - Prior to the collision, there were no warning signals from the dashboard. - I was not injured from the accident as I was only able to go around 27-33mph due to a tractor trailor clearing the exit in front of me. No others were involved. - The manufacturer sent an inspector to look at the vehicle and test drive it. However, they did not test drive in the same conditions I was in or at. - The issue was not reproduced by another party. (Photos were taken the next day)
