On 6/7 while driving 65 mph I hit a deer on the driver front. My car detected the crash and deployed every airbag inside the car. I received an injury to my legs from the driver's airbag under my steering wheel. If this airbag were not there, I would have had no injuries from this accident. I have missed work and was seen at the local ED for treatment.
I was driving my 2024 Toyota Corolla SE gas model (with the convenience package) on the interstate in [XXX] during stop-and-go traffic. Traffic had been moving slowly for about 15 minutes, and I had Brake Hold turned on, cruise control was off, Proactive Driving Assist was on. I was behind a semi truck and was moving very slowly, getting ready to stop. I had maybe 3 or 4 car lengths between me and the semi so they could see me in their mirrors. As I was about to stop, the brake pedal suddenly went all the way to the floor, the car jerked to a stop, and the electronic/emergency parking brake applied on its own. I put the car into Park and then back into Drive, and the problem did not happen again during that drive. There were no warning lights, dash lights, or warning messages before this happened, and there were also no warning lights or dash lights afterward. The issue happened suddenly with no prior symptoms that I noticed. I believe the brake system, Brake Hold system, electronic parking brake system, or a related brake/vehicle control system malfunctioned. This put my safety and the safety of others at risk because the car unexpectedly stopped abruptly in interstate traffic. Since I was in heavy stop-and-go traffic and other vehicles, there was a risk of being rear-ended, causing a crash, or becoming disabled in traffic. I took the vehicle to a Toyota dealership after the incident. They were not able to reproduce the problem, but they did find stored code C14FE14. They told me they checked the brake system, cleared the code, tested the steering angle sensor connector, and said everything tested within specification. They also performed a multipoint inspection and said the battery, brake pads, and other inspected items tested well. To my knowledge, the vehicle has only been inspected by the Toyota dealership/service center. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
"I am reporting a fatal crash involving a 2024 Toyota Corolla (VIN [XXX] I do not know the exact mechanical cause, but the following symptoms occurred: 1) The driver reported dashboard lights (red and blue) flickering on and off, windows and locks going on or off. 2) There was hesitation in acceleration after taking off, 3) The vehicle failed to stop and went airborne causing a FATAL accident. Insurance Co. failed to investigate porperly and sold the car To Co-part without waiting for Probate forms to be complete for this vehicle and the Estate. We have discovered this car was an Avis fleet vehicle sold as 'new' at Beaver Toyota. I am requesting a federal investigation to determine if a mechanical or electronic defect caused this loss of control."

The contact owned a 2024 Toyota Corolla. The contact stated that while the vehicle was stopped on a curb with another vehicle approximately 8 -10 feet ahead, the brake pedal was depressed to shift into park; however, the vehicle independently accelerated. The contact stated that because of the failure, the contact's vehicle rear-ended the Honda CR-V vehicle that was parked in front of the contact's vehicle. The contact stated that the vehicle's speed was only 3–4 MPH. No air bags deployed. The other vehicle sustained damage to the rear bumper. The contact's vehicle was towed to a local tow yard. The contact's vehicle was condemned as a total loss by the insurance adjuster. No police report was filed. No injuries were sustained. The manufacturer was made aware of the failure. The failure mileage was approximately 10,000.
My vehicle will jerk into the left lane of the road when lane keeping assistance is activated. It appears isolated only to situations when I am travelling on roads that were recently repaved and lines haven't been painted yet. However, these roads are equipped with consistent reflective indicators marking the center of the road because these roads remain unpainted for months. There are many of these roads where I live so it is a frequent issue that I experience multiple times everyday. I have never allowed the vehicle to fully execute it's correction in fear it would drive off of the road or into oncoming traffic but it is a very scary event when my car tried to kill me.
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.
When the sun is overhead (this happens daily in South Florida) the reflection of the ambient light on the instrument panel cover makes it impossible to look at the information on the instrument panel. This essentially makes one drive while being blind. Not a safe concept. It is pathetic that no action has been taken against the company.
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.
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.
Rear camera stayed on while I was in drive. I parked, turn off the engine, restarted, and the camera stayed on while driving. I changed gears to reverse and then to drive, but no change.
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)
[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)
Ever since my vehicle was new, the driver side blind spot monitor will periodically not work. This issue occurs primarily when starting the vehicle using the Toyota app, but also will have the issue when starting the vehicle normally. When all conditions are met, the driver side blind spot monitor will fail to illuminate during an entire trip unless the driver either: turns the vehicle off and back on, or: goes into the vehicle settings while driving and turns the blind spot monitor off and then on again. Upon doing either of these things, the driver side blind spot will resume normal operation. The issue has been confirmed by a Toyota dealership and is on file for my vehicle, and I also have video footage of the issue. While the dealership was able to witness the issue, the vehicle produces no codes and so the Toyota engineer advised it was a condition issue and not a vehicle issue. But this issue has been happening to me randomly since I got the car, and all of the facts point to this NOT being a condition issue. There are also SEVERAL other complaints on Toyota and Lexus forums for this exact same issue for varying models such as the Corolla Cross. This is a safety risk and can increase the possibility of a crash. While blind spot monitoring is intended to be an aid and should not be solely relied upon, inevitably there are drivers who will rely on that blind spot monitoring, not know it's broken, and potentially get into a collision due to the system leading them to believe the coast is clear, when it indeed is not. The first time I noticed it, which was within one week of owning the car back in January 2024, I was trying to get over to the left, saw that the blind spot was not illuminated, and almost made the turn except I checked manually first and saw there was a vehicle in my blind spot that the car did not pick up on. The fact that all it takes it turning the car off and on again leads me to believe this is a safety defect that needs addressed.
Brand new car with 300 miles jerks and jolts leaving from a stop and hesitates going up hill. Feels like car has no power behind it. Forward collision also breaks randomly. Currently at dealership.

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)
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
