Toyota RAV4 Prime abs comes on

Filed Dec 4, 2025 · Airbags, Brakes · NJ · crash

During snowy but manageable conditions, the brake system on my 2021 RAV4 Prime SE failed to respond, and the vehicle did not decelerate when I pressed the brake pedal. A “Pre-Collision System Malfunction” warning appeared shortly before impact. I was unable to steer away despite attempting an evasive turn. The vehicle collided with the car in front of me, and the airbags did not deploy. I was driving at a reduced speed due to snow. The vehicle ahead (a BMW SUV) began slowing. When I applied the brakes, my RAV4 Prime did not slow down at all—there was no deceleration, no ABS pulsing, and no traction control intervention. The vehicle continued moving forward as if the brakes were not engaging. At the same time, I saw a dashboard warning indicating a Pre-Collision System (PCS) malfunction. I attempted to turn the wheel to avoid the collision, but the vehicle did not respond to steering input quickly enough to prevent impact. Despite the collision, no airbags deployed. The vehicle has been regularly maintained (oil changes every 5,000 miles, new tires last year, all service intervals followed), and there were no warning lights or issues beforehand. Safety Concerns: •Complete or partial brake failure •Electronic braking or stability control malfunction •Pre-Collision System malfunction •Airbag non-deployment in a front impact •Potential systemic issue affecting Toyota hybrid/Prime models This incident caused significant fear and distress for both me and my child who was in the vehicle, and raises serious concerns about whether similar failures could occur for other owners.

The car has a grinding sound and a brake slipping feeling that occurs while traveling and braking over rough pavement. It does not happen consistently, but it does happen fairly regularly (every 2-4 weeks). Note, the grinding sound can range from subtle to quite loud, depending on bump/timing of braking. This has been happening since I purchased the car and continues to happen, which is why I put today's date as the incident date, and I have been bringing it up with the Toyota maintenance department at most maintenance appointments. Their shop manager has driven it and thought I was mistaking it for the ABS activating. I have driven it with him, ABS has activated, and when he pointed it out to me, I have let him know that what is happening is definitely something different than the ABS activating. I have tried to find a location to show them to replicate it with the service center, but it happens randomly on rough patches. For example, it happened on a spot near the dealership that I thought I could use to show them, but when I drove over the same area again and braked, nothing happened. So, I have not been able to replicate this with the service center, but it is most certainly happening. I have notified Toyota through their consumer contact system that this issue is going on and they said Toyota tracks issues like this. However, no resolution has been offered. Other Toyota Rav4 Prime owners of the same year have experienced this (see [XXX] and [XXX] ). Although the maintenance manager was stumped, he said at a recent visit that another Prime owner voiced the same type of thing happening. Toyota needs to investigate to determine what the issue is and remedy the issue. I am concerned this could lead to a larger issue and is a safety recall issue that warrants immediate attention. It does not seem that Toyota is taking this seriously. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On the night of [XXX] at approximately [XXX] PM, I was driving from Tracy, California to Lancaster, California via the [XXX]. The freeway had no traffic at the time, and I set my cruise control to maintain a speed of 75 mph for a safer ride. While driving in the left lane near Santa Nella, my car suddenly deployed the ABS brakes. The steering wheel locked, and the car began to slip—its tires locked as if on a roller coaster going downhill. The driver’s side then rolled over and crashed. Fortunately, the road was empty, and I did not hit anyone during the accident. I thought I was going to die, but I am lucky to be alive. suddenly Abs brakes deployed steering wheel lock right side this reason I have very accident. I believe the car has manufacturer defects. First, the door handle on the driver’s side is positioned too close to the driver’s left arm. Second, the center console on the right side—intended for resting the driver’s arm or storing extra items—repeatedly hit my ribs during the accident. During the crash, the driver-side door handle struck my left arm multiple times. Orthopedic surgeons reviewed my X-ray and found that my forearm was fractured in three places. They recommended surgery. The center console also struck my right ribs repeatedly, causing swelling and pain. Fortunately, my ribs were not broken. My chest & ribs swelling and pain right side shoulder I have pain my head & neck pain My car was declared a total loss. I respectfully request that these issues be investigated, as I believe another driver could sustain similar injuries in a future accident involving this vehicle model.

Upon entering a light controlled intersection at a relatively slow speed (probably less than 20 mph} on wet pavement, an oncoming car suddenly made a left turn directly in front of me. I applied the applied the breaks hard and slid into the passenger side of the turning vehicle. The ABS system did not function. The air bag did not deploy. At the moment of the collision my speed was reduced and I do not know the threshold for airbags to deploy, but this was a direct front end collision. I was able to brace myself and was not injured. I am not claiming the airbag malfunctioned as the speed at the moment of impact was not high. However, I have complained to the Toyota dealer service department almost since the car was new, that the ABS does not function. They have repeatedly told me that it is fully operational based only on the fact that the system registers as "on." Being "on" does not mean it is functioning. Questions: What component failed? ABS and possibly airbag How was my safety at risk? Non functioning ABS resulting in a potentially preventable accident Has the problem been confirmed? Yes, byt the dealer though they claim the sliding of the car is due to old tires. However, the tires are withing the legal limist for tread depth and I have complained about the problem since the car and the tires were nearly new. Has the vehicle been inspected? yes, byt the Toyota dealer and an independent Toyota crash inspector Were there any warning lights etc? No

I have owned vehicle for 3 months. Noticed loud banging sound whenever brakes are applied at low speeds, on rough bumps/rough road. At times banging is loud enough to sound like vehicle hit something. No issues with braking currently. Not sure if noise is from ABS but sound is coming from front and back. Toyota inspected vehicle and said sound is the ABS activating..."totally normal for newer hybrids and no fix at this time...test drove other 2024 Rav4 Primes and all had same noise". TAS#242180433. No accident/incident to report at this time, however noise is loud enough to cause uneasiness while driving.

Driver was parking the car in a parking lot at a very slow speed. The car suddenly shot forward at a very high rate of speed, requiring evasive steering from trees and a fence, until the car crashed head-on into another vehicle. The driver is very certain the brakes only were applied during the entire time the car shot forward. Airbags were not deployed. Bystanders were within six feet of the car at one point during the acceleration, prior to the crash. There were no injuries. Earlier, on the day of the crash, the car had a sudden, strong, yet brief acceleration of the vehicle during normal braking while approaching a rotary, unlike normal ABS. ABS itself seemed unneeded (the approach to the rotary was well within the speed limit, on dry condition roads). This issue occurred twice in the two months prior to the accident. There were no known warning messages in the car or the phone app for the car in any of these cases or at the time of the crash. The manufacturer has been notified of the crash, a product liability case has been opened, and an engineer was sent to look at the car. A data download from the airbag event data recorder (Bosch CDR) was done, a report was generated, and the report was provided to the car owner. No data in the formatted report is provided regarding Vehicle Speed, Accelerator Pedal, Cruise Control Status, Brake Torque, etc. Unformatted hexadecimal data is included in the report, without a data schema to decipher the data. It is not known if any other analysis or information about the car was reported by the engineer, beyond the Bosch CDR report. The owner is not aware that the problem has been reproduced or confirmed by anyone involved, or of any other inspections than the one described here. Manufacturer has not yet provided the owner with a report response. The car is currently at an auto repair shop and no repairs have begun. The shop is awaiting an appraisal by the insurance company before doing the repairs.

We have COMPLETELY lost brakes on MULTIPLE occasions for a few seconds per occasion. Brake loss has occurred upon slow, even braking and on flat, dry, even pavement with no pot poles or loose gravel around. When this happens, an orange light appears on the dash, we lose brakes for a few seconds, the car regains brakes, and jolts forward with no change in foot position on the brake pedal. We have taken the car to the dealer multiple times and every single time this incident has occurred the rear right wheel speed shows about a 10% variation in speed compared to all the other wheels per the vehicle diagnostic report/record of behavior. The orange light we are seeing on the dash is the ABS light. There is no feedback in the brake pedal on any occasion. This incident has occurred about 20 times so far. Our car is available for inspection. The dealer believes this is being caused by a software issue and not a faulty sensor. This car is a danger to us and anyone around us as we have needed to swerve into the shoulder multiple times to avoid hitting someone ahead of us. This NEEDS to be fixed before it injures or kills someone. This issue has still been persistent even after taking care of the VSC recall and a reset/recalibration to the braking system. We have taken the car to the dealer for this issue on: 4/4/22, 4/15/22, 4/25/22, 5/11/22, 6/4/22. *We have been limiting our driving in this car due to the issue happening multiple times a week, that is why there hasn't been many trips to the dealer much between May and June. I want to reiterate, this doesn't sound like a defect per the dealer, it sounds like a software issue!

My RAV4 PRIME was in stop and go traffic. Brakes did not switch from regen braking to physical brakes. Slammed on the brakes several times, they did not slow the car enough. Eventually the brakes locked up as the RAV4 rear ended the car in front. Pushing that car into the one in front of it, and that one in front of that, and that one in front of that. Causing damage to three other cars. Two other people are claiming medical, the driver went to the ER. Air bags did not deploy. Taking to the repair shop. They were shocked that the air bags didn't go off given the the condition of the frame. Toyota Motor North America (TMNA) did an inspection to read the event data recorder (EDR). Brake were applied at -1.5 seconds before impact. And here is the weird part, saying that the ABS activated then too. There was no notification, and the brakes locked up. Speed went from 46 to 21.1 mph. This occurred at 3,573 miles on only a few month old RAV4. I'm well aware of what ABS feels like when it goes off.

While exiting an interstate and applying the brakes, the vehicle struck a small bump (pot-hole) in the roadway with the front passenger wheel. The car lurched forward and stopped slowing down. The brakes had disengaged on all wheels. After approximately 2 seconds, the car started braking again and I was able to regain control and stop. This momentary loss of braking ability could have caused me to rear end the vehicle in front had I not left excess room. The loss of brakes increased the braking distance required and could lead to the loss of control if the roadway is slick. I have been able to reproduce this issue. No ABS or TCS lights illuminated. No beeps or other warning messages materialized. The car is available for inspection upon request. It appears to be an issue with the regenerative brakes switching over to the mechanical brakes when the car believes there is wheel slip.

I am experiencing inconsistent brake feel after ABS actuation during slow and steady application of the brakes on rough or slick road surfaces. Stopping distances are increased compared with my expectation for a given pedal force. Please note that the 2010 toyota prius had a similar issue, and a recall was issued under the federal safety agency campaign 10v039000.
