There are 5 owner-reported driver assist & adas complaints for the 2023 Toyota Corollain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Since purchasing this vehicle new, I've had several occasions (not on just the most recent date noted in this case) where the car will issue a false Pre-collision Alert and apply the brakes for about 1 second while using the Adaptive Cruise Control. However, this happens while me and the drivers around me are driving "normally" and there are no vehicles in front of me nor attempting to merge into my lane. There does not seem to be a particular set of conditions that cause this false alert and they happen randomly, but it is startling when they happen since there is no observable reason for it. Fortunately, there has not been anyone tail-gating me when this happens because this could easily cause a rear-end collision if someone were following too close. I've notified my local dealer about this issue more than once, but they cannot find anything wrong.
There's an electrical problem going on with all Toyota vehicles coming out with the new navigation system where goes out and keeps rebooting. Multiple times on cars a year have reported this issue. Causes a distraction as screen goes on and off randomly as you drive and backing up. Also without it you can't see your GPS and find routes. Just simple search and there's many complaints about this issue from consumers being affected as fast as 10 miles into owning car to month or six. Not worth repairing as goes out every other month and don't even last a year before goes out.
The Lane Departure System works poorly on county 2 lane roads. It is constantly obtaining and losing track of the left/right hand sides of a lane. (For reference, my 2017 Toyota RAV4 has no issues tracking the edges of these same roads.) The issue is that when it obtains tracking just before entering a curve, the system jerks the steering wheel in the direction that it thinks the vehicle needs to go. This happens suddenly and forcefully with no warning and I have had several instances where the system has steered the vehicle into the opposite lane or almost sent me into the ditch. System works fine on well lined interstate roads.
The Adaptive Cruise Control and Forward Collision Warning DO NOT work in the rain. I have had 2 instances when using ACC where the vehicle would continue the set speed even though vehicles in front of me have slowed down. I have had to manually brake to avoid rear ending the vehicle in front of me. I have had 1 instance where a vehicle merged into my lane and barely missed the front of my vehicle although my vehicle continued at the set speed and I came within what appeared to be inches of that vehicle and had to manually brake to avoid a collision. This always happens when cruising on the interstate in the rain...system works fine when dry. This is apparently an issue with all Corollas or Toyota Safety Sense 3 because the dealer told me they have had several complaints about this.
Just today, I was driving my 2023 corolla when I accidentally rear ended someone. We were getting off the highway and they were taking a right turn and second guessed themselves while I was focusing on the oncoming traffic. Usually my car would notify me of there being an obstacle in front of me as it is equipped with a pre-collision system. This time however, it did not brake or notify me resulting in me rear ending the car in front of me and causing damage to my car.
