Automatic Emergency Braking Problems of Toyota Corolla

There was a recall on my vehicle for the skid and emergency braking and was told it was taken care of Feb 2025 at my service appointment. I was involved in a car accident on Aug 11, 2025, everything that was supposed to be fixed in the recall did not operate during my crash. I reconfirmed with the dealership that they did the recall repair and they again said yes but if they did then the repair completely failed. There was no emergency braking available, the car skid a long distance, no airbags deployed even though all sensors in the front were engaged and collision center confirmed they should have gone off. Vehicle is currently at collision center and is available to be inspected.

I was driving down the road, slowed down and moved over to the left side of the lane as I was passing a bicyclist. The car interpreted the bicyclist as a car and applied aeb. The aeb was not fully applied, thankfully. The car did not come to a complete stop. If it did, I may have been rear ended by the person behind me.

The emblem on my car contains a sensor/radar for adaptive cruise control and foward collision warning that is also connected to automatic emergency brakes. The safety of me and my [xxx] old are at risk because if I needed assisted braking/collision warning, my car no longer provides that. The braking on my car feels as if I am needing to apply a lot of pressure on the brake to stop completely or even to come to slower speeds to adjust to traffic. The problem was reproduced prior to me officially picking up my car on [xxx]. The estimator told me that he isn't quite sure what is causing the sensor issue but according to the calibration system it is working fine and he doesn't know how to fix the issue. As for the brakes he said that they feel fine to him. My car was inspected by crash champions and I have been told that my vehicle feels fine and the sensor is working fine according to the calibration system. My car did not originally have this issue until after an accident on [xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was leaving out of the parking lot of the shops santa anita. I was parked underneath by [xxx] and proceeded to to leave and turn out right towards the wide open parking lot. At the time I was leaving, it was completely empty. This parking lot is wide open as I was leaving and I’m going no more than 15 mph when suddenly a beeping sound goes off and the car slams on its brakes on its own! I didn’t even have enough time to stop on my own and look to see what the alert sound was. The car stop and jerked me so hard and slammed forward so hard. Thankfully I was in an empty open parking lot. That would have cause a very bad car accident and I would have been badly hurt and the car that would have slammed into me from behind! this has left me with so much anxiety and I am now very scared to drive this car at all even. I haven’t even had this car for a year and this is the second time I’ve had an issue with it. And I tried explaining to the dealership that for the past couple weeks to month that when I drive the car, it has this pulling feeling when I’m coasting. It has never felt that way before. This is supposed to be a new car. It doesn’t even have 15,000 miles on it yet! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Dear better business bureau, I am filing a formal complaint against Toyota motor north America regarding a serious and unresolved safety defect in my 2024 Toyota Corolla le (VIN [xxx]). The vehicle experienced two incidents of sudden unintended acceleration—the second, on [xxx], resulted in a collision. Despite my repeated efforts to resolve the issue, Toyota has failed to respond adequately or provide critical diagnostic data. In both incidents ([xxx] and [xxx]), while stopped at a red light, the vehicle suddenly surged forward despite my foot being on the brake. On [xxx] this caused a collision. My vehicle has remained undrivable since. Toyota conducted a diagnostic inspection on may 29 under case #[xxx]. I’ve repeatedly requested access to the raw data from this inspection to understand the defect, but Toyota has not responded. Emails to the assigned case manager, ms. Cynthia ware, have gone unanswered. When I was directed to reply to a support email, it bounced back as a “do-not-reply” address, redirecting me to a login page which falsely claimed I had no active cases. This created an endless communication loop. Toyota’s lack of transparency and support is unacceptable—especially given the severity of the issue and the fact that the vehicle is still under warranty. I am requesting: immediate release of the raw diagnostic data from the may 29 inspection a prompt resolution, including full repair, replacement, or buyback clear, responsive communication from an authorized representative this is not only a financial burden, but a serious safety risk. I respectfully request bbb’s assistance in securing a resolution and holding Toyota accountable. Thank you for your time.

The automatic emergency breaking and forward collision warning failed to alert and turn on and I wrecked into an object. My life was put at risk and I wrecked my car. The problem has not been reproduced or confirmed by the independent service center. The vehicle is currently being inspected by insurance estimator. There was no other alerts or messages to alert prior to collision.

Brakes are hard when pressed. Check engine light is on and when I had it checked I was told that it was an issue with the abs.

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.

On [xxx], around 7:45 pm, my husband and I were driving on [xxx] from atlanta to visit family at john’s creek. We were driving at a steady speed of approximately 70mph on the second lane from the left when all of a sudden, the vehicle displayed a 'malfunction' alert and began swerving uncontrollably. Despite our attempts to regain control, the car swerved right, striking another vehicle three lanes away. We had no control over the steering or bringing the car to a safe stop. After colliding with the other vehicle, it then returned to its original lane and came to a sudden stop with a message displayed stating 'shifting to p'. During this incident, an sos call was automatically placed to Toyota, and we were subsequently connected to 911 through them. Our vehicle got damaged due to this and so did the other vehicle that got hit. The vehicle not only endangered our lives but was also a potential harm to others on the road. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

We were driving on [xxx] near norcross, GA about 200 ft from exit [xxx] at a constant speed of around 70 mph, when suddenly the vehicle displayed 'system malfunction' and started veering on its own and the brakes wouldn't work. It kept veering to the right and crashed into a vehicle 2 lanes away and rebounded back to the original lane and came to a halt with a message displayed 'shifting to p'. The malfunction and loss of control, along with the brakes not functioning those few seconds/minutes put our lives and others' on the road at risk. The vehicle is available for inspection. The vehicle was towed on the day of the accident and then taken into a Toyota dealership and is currently there. The vehicle has not yet been repaired. Toyota sent a third-party inspector to gather data from the vehicle but that turned out to be merely the crash data up to 5 seconds prior by which time the malfunction had already occurred and the vehicle speed was down from 70mph to 31mph. The incident occurred on Thursday, [xxx]. We do not feel safe driving that vehicle again. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was sitting idle in my car. The two cars crashing icon came on even though I was in the parking lot doing nothing. There was also issues with the other indications where I would use the back arrow on my steering wheel to clear the issue and it would not clear. Seems unsafe and scary.

[xxx] in reading the above article, Toyota recalled Corolla cross hybrid vehicles with many complaints and situations mirroring our accident. Before the accident, the vehicle displayed no warning signs. Despite the driver pressing the brakes and the assisted braking feature seemingly turning on (e. G. , signal lights on the computer system), neither seemed to work in this situation. The damage was far too severe for the assisted braking feature to have activated, along with the driver pressing the brakes. After viewing the matter with those involved in the accident, many of us concurred that we believe either the braking system or the computer system failed. In the aftermath of the accident, the police, manufacturer, or third party hadn't reviewed the vehicle's status. On top of that, our insurance refused to investigate, urging us to discuss the matter with Toyota. Thus, we'd propose that the Corolla se may experience an issue similar to the vehicles in the article. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

The anti-lock brake system (abs) malfunctioned when the vehicle was still very new, with only 25,000 miles. Diagnostics from two independent service centers confirmed that the abs electronic control unit is failing due to an external failure. Both specialists stated that such a failure is highly uncommon and is a clear quality issue related to the electronic components. A critical system like abs should not fail this early, raising serious concerns about the durability and reliability of the vehicle’s braking system.

I was going to work on 12/15/2022. There was a stop sign and I needed to take a right turn in order to join the freeway-10 east highway to head on to work. It was about 6: 40 am approximate time. There were too many cars ahead of me at the stop sign. My brakes failed to hold on while I waited for my turn. There were at least 3-4 cars ahead of me. Therefore I did not want to hurt anyone or any other car ahead of me. Therefore I veered off to my right-hand side where there was some space and tried to stop the car but it did not do so. Therefore, my car had to hit the high-way pole to come to a stop. The airbags deployed and hit me more to my right side. The car got totaled as per California casualty insurance information. I am glad to be alive. I went later to the hospital as there were no direct visible injuries.

Hit an embankment and car went 60ft then hit fire hydrant and other objects but drivers side airbag didn’t deploy.

I purchased my Toyota Corolla se 2021 in may 2021 with 11 miles on it. I received safety connect trial for one year. It was so unsafe. I believe there was an invasion of privacy because after requesting my data held at Toyota corp. , I read of times of install/deactivation that were not proper in accordance of my purchase and my understanding of the set up at time of purchase. It appears this safety connect was already connected before my purchase, which is a safety issue and is a violation of privacy and lead to data breach. With my connected device, iphone, acting crazy and miss reading my locations and redirecting, etc. , I was on my way to apple in December 2021 with 2016 miles on my car. I believe the remote connect was being controlled by others as up to five devices are allowed on the module. Gps worked accordingly obviously, because when I exited the interstate, immediately my engine stalled out at 50 miles an hour in the rain. I was scared to death and found the closest gas station to pull over and stop my engine. About 30 minutes later, I continued to apple, 1 mile away. After restarting my car, I was alerted to be safe and contact my provider. I found out that that meant that my control module was blown. This has affected me in a few ways. Maps have read I am in china, south florida, north, florida, georgia, California. I also went to the local Toyota for an oil change and tire rotation in October 2022 and learned that I needed a tire replacement and the pressure was down to 15 pounds. No light appeared. If the communication module is destroyed, then all of the safety features are, as well. No lights alert, no blindspot warning days, automatic emergency, braking has failed as well, as I recall when it worked and it is not even sensing a vehicle or anything in front of it. Also the red signs that display, stop, certain miles per hour, etc. Are reading incorrectly. Furthermore, Toyota wants to disclaim all warranties associated.

Around 1900-2000 miles of ownership, 6 months after purchase, I was driving on i95 in the rain, 65 mph, traffic in west palm beach, FL, on my way to apple(mall). Upon exit, my engine completely stalled out. I pulled off road, not smoothly at all, turned off the car and it restarted 30 minutes later so I resumed my travels. The next day, my vehicle alerted me that the communication module had blown, not in those words. I had called Toyota and told the representative of the spoken alert and she informed me to go to dealership. They were clueless how to fix and reset battery. This communication is vital for all modules to perform safety features. Today I had a large screw in tire and no alerts of low pressure. Tire read 12 lbs pressure. My lane departure/correction doesnt work half of the time. My attorney has informed me that he hears there are concerning issues involved and noncompliance has led to him filing suit today. Software source code leaked and left open on github for 5 years has compromised the safety of all connected customers and their devices.

Transmission went out at 28k miles. New transmission put in by service department lags or gets stuck at 5000 rpm’s and won’t shift. Forward collision warning light comes on with nothing in front of vehicle at random 2 times it’s trigger automatic braking.

I had a car accident on January 15, 2021. My car was totaled and none of my air bags deployed. My emergency brake sensor didn't go off as well which usually always goes of for any minimal close object. Because of my air bag not deploying I cut my lip outside and inside going to the hospital and getting a stitch in the inside of my lip. I had a hole the width of a dime from hitting the steering wheel and bled non stop from my nose and lip/mouth. The hospital has in my chart the picture of the hole.

I have a 2019 Corolla hatchback xse the main problem is that at least in 30 occasions the car doesn't respond when I push the accelerator has almost caused a accident at least 3 times. I have taken it 2 times to the dealer. The first they told me they knew of the problem but there was nothing they could do since they didin't have a fix. Last time I took it about 2 months ago they told me my car wasn't in the recall list. I checked the part and it is in fact the model that has the issue. What are they waiting for me to crash.

Drive assist occasionally swerves out of lanes at parked vehicles, pedestrians, and even cars in on coming lanes. Happens inconsistently and is unpredictable. When the car is perfectly centered with drive assist on, you begin to let your gaurd down. Which is when you least expect your car to forcibly turn the steering wheel at an unsuspected bicyclist.
