2018 Toyota Camry: false forward collision warnings

Filed Oct 26, 2026 · Brakes, Driver assistance · TX

Vehicle Safety Complaint – 2018 Toyota Camry On October 26, 2026, the driver was operating a 2018 Toyota Camry on a public roadway at approximately 45 mph when the vehicle unexpectedly activated its automatic emergency braking system. The dashboard displayed a “BRAKE!” warning, immediately followed by extremely forceful braking, comparable to someone suddenly slamming their foot on the brake pedal. The vehicle rapidly decelerated from approximately 45 mph to a complete stop, despite there being no vehicles, pedestrians, or visible obstacles in front of or near the vehicle. The sudden braking caused the driver’s body to lurch forward. According to the driver, the seat belt did not noticeably tighten during the incident. After the vehicle came to a complete stop, the brakes released, and the car slowly began rolling forward without the driver pressing the accelerator. The driver did not intentionally initiate the emergency braking. This unexpected activation created a serious safety hazard and could have resulted in a rear-end collision, loss of vehicle control, or serious injury. The incident raises concerns about a possible malfunction of the vehicle’s Pre-Collision System (PCS), including its radar sensor, forward-facing camera, calibration, or associated software. A VIN search through the federal safety agency database indicated zero outstanding safety recalls for this vehicle. I am requesting that the federal safety agency document and investigate this incident as a potential safety defect involving unintended automatic emergency braking in the 2018 Toyota Camry.

I was driving my daughter to work then all of a sudden 6 different vehicle alerts came on my dashboard. Vehicle Alerts: advanced ultrasonic detecting and ranging system, lane departure alert, pre-collision system, parking brake system, vehicle stability control system, and secondary collision brake system. I was at a stop light then the car would not drive it was like it started stalling. I had to put on my hazard lights then turn the car off and back on. That's when I was able to accelerate to 20 mph to get out of traffic. I could not give to car any gas to move. I pulled over to a doctor's office parking lot. The car would not go into reverse. Once again, I had to turn it off and on. I had to eventually put it into neutral and cruise all the way home. Once home the last alert came on which was the check engine light. I had the car towed to my nearest Toyota dealership. Toyota kept my car for over 24 hours. I had to go back up there to inquire about my car. That was when I was told it was my transmission and they quoted me $9,338.96 ($2,479.87 labor for 12.4 hours, $ 6,808.92 part, $50 for shop supplies) to get my car repaired.

Pre-Collision system malfunction, secondary collision system malfunction along with check engine. It appears to be a trend with 2018 Toyota Camry XSE and higher model. I found that many people that own this model vehicle is experiencing the same issue even after going to a Toyota dealer and the issue still persist.

Only when it rains the forward collision warning light comes on. The last time it came on the engine light also came on with code P01280. Diagnostic at Toyota said the Thermostat needs to be replaced. I decided to look into this as the thermostat should not be bad at 54500 miles. Weeks later and the neither light has come on again.

Shifted the operating car from park to drive when the car suddenly and unexpectedly took off even though I was not touching the accelerator. The car accelerated across the street and slammed into a parked car. The airbags did not deploy which would indicate a low-speed but the pre-collision system did not stop the car which would indicate higher- speed. My car was written off as a complete loss by my insurance carrier and the damage to the parked car that was hit was extensive.

There are multiple warning lights on my dash at this time. The following malfunctions are showing on my dash at this time: Pre-Collision System Malfunction, LDA Malfunction, Headlamp malfunction, SRS Malfunction, Low Braking Power, Secondary Collision Brake System Malfunction, Power Steering Malfunction, Antilock Brake System Malfunction. These started coming on around two weeks ago. I have no blinkers available and my steering stiffens to where the car is almost undriveable. I contacted Toyota corporate office and the representative said she has not heard of these warnings, but they are on many Toyota forums on the internet. I took the vehicle to Toyota North in Goodlettsville, TN on 10/12/2022 and they can not tell me what is wrong with my car. I feel it is a safety hazard to drive this car at this point since this car has automatic braking power. I also have videos available, if needed. This is going to cause someone to get seriously hurt.
