This Problem Across All Years
I am reporting an ongoing safety issue involving the Skid Control ECU and loss of power break recall on my 2024 Toyota corolla hybrid. The first time, my vehicle experienced loss of power brake assist and displayed a “Hybrid System Malfunction” message on screen. I towed my car to Toyota, confirmed it was related to the Skid Control ECU recall and repaired it under the recall at no cost, they did a software update. The second time, the exact same problem reoccurred. I had the vehicle towed again to a Toyota dealership, but this time, they refused to perform diagnostics unless I paid out of pocket for a 12-volt battery replacement. The dealership stated they cannot confirm if the issue is recall-related until diagnostics are complete, but they also refuse to complete diagnostics without me paying first. My vehicle is currently undrivable and unsafe, and I rely on it for daily transportation and work. So they made my pay for this 12v battery to do the diagnostics and now they tell me it is not recall related but one of the relays not working, the repair will be cover under warrant but i had to pay for battery and rental cars . I believe Toyota is in violation of its obligations under 49 U.S.C. §30120, which requires manufacturers to correct recall-related safety defects free of charge. This issue leaves me without a vehicle and unable to verify that the recall has been properly resolved. I have opened a case with toyota brand engagement. I am requesting that NHTSA review this case and ensure that Toyota complies with recall repair requirements so my vehicle can be safely diagnosed and repaired without charge.

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.

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.

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)

I was able to distinguish today the car noises my vehicle is making happens when I break. Like a “eeeeek” sound. My mileage is under 8,000, had the car almost a year. Also I notice my wheel stiffens. I’m able to verify it happens when I merge - specifically when the lane dashes end. The wheel somehow gets tight even when driving with both hands. As if the vehicle gets confused. This has happened about 5 times this year but every time it happens- I brace myself for the vehicle to crash since I can’t control the wheel, no matter how strong I try to gain control. The wheel gets too tight to steer. These episodes lasts about 3-4 seconds. I am going to take it to the dealership on April 1, 2025. Also there were no messages on my dashboard when these episodes occurred.

[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.
