2023 Toyota RAV4 driver assistance problems

SAFETY RISK!!!! Component: Forward Collision Avoidance / Lane Departure / Electrical System / Exterior Lighting Description: While driving my 2023 Toyota RAV4 XSE, the dashboard suddenly displayed simultaneous critical safety errors: "Front Camera Unavailable," "RSA Malfunction" (Road Sign Assist), and "Pre-Collision System (PCS) Malfunction." Recently, the "Headlight System Malfunction" warning also triggered because the Automatic High Beam (AHB) system relies on the same sensor. An official diagnosis by a certified Toyota dealership confirmed Diagnostic Trouble Code (DTC) C1A9447: Image processing microcomputer in front recognition camera watchdog/safety MCU failure. The dealership confirmed this is an internal component hardware failure requiring a full camera replacement and ADAS calibration. Safety Risk: This manufacturing defect completely disables the vehicle’s Pre-Collision System, entirely removing automated emergency braking, lane-keep safety features, and automatic high-beam headlight safety controls without warning. Driving without automated emergency braking puts the driver, passengers, and surrounding traffic at an immediate risk of an unmitigated collision. Toyota is aware of these microcomputer watchdog failures via internal Technical Service Bulletins but is forcing consumers to pay over $2,100 out-of-pocket to repair a failed factory safety module. A formal safety investigation and recall are urgently required to address this widespread component defect.

Was pulling up to park in a space inside a parking garage. To properly be within the parking space, one had to park a little bit on a slanted slope so as I was turning the car to the right side, to park, I went to tap the gas pedal to ensure I had enough momentum to properly be parked within the parking space. When I tapped the gas pedal, the car accelerated with a lot more speed and momentum than I anticipated. The car slammed into the wire wall and the inside wall of the parking garage. The anti-collision features did not activate and the acceleration achieved was disproportionate to the amount of pressure on the gas pedal. Luckily no one was harmed and no other vehicles were damaged. I don't recall seeing any type of warning or alert during this event. I believe the car was going from EV mode to Non-EV mode and that caused the sudden unexpected acceleration. The vehicle is currently at a collision center for repairs but I wanted to report this incident as I do not believe it was driver error, I do believe that this vehicle had a few components fail.

1. System Failure & Availability: Vehicle's automated driver-assist (Lane Tracing/Keeping Assist) and steering modules failed. The vehicle is intact and available for inspection under a strict spoliation hold at an independent facility. 2. Safety Risk & Injuries: On a curve at ~50 mph, the automated steering suffered a violent uncommanded intervention, overrode human control, and jerked the wheel out of the driver's hands, causing a head-on collision with a tree. Injuries required immediate ambulance transport. Diagnoses include a concussion, a severe large left leg hematoma with extreme swelling, open wounds, and deep tissue trauma causing foot numbness. This required a secondary ER return and an active orthopedic referral from a specialized Wound Care Center. 3. Problem Reproduction: The vehicle was rendered a total loss and is non-operational, preventing physical test-driving. The defect is expected to be confirmed forensically via electronic diagnostics. Onboard modules contain recorded Pre-Crash Steering Torque Discrepancies and Vehicle Control History (VCH) metrics showing the automation overrode manual input. 4. Inspections Conducted: The manufacturer's corporate liability division opened an accident investigation. A signed Imaging Authorization form is executed; corporate technicians have contacted the driver to finalize the date to download Event Data Recorder (EDR) logs at the yard. The auto insurer explicitly refused to inspect the vehicle or download data, citing a 4-month policy lapse. 5. Prior Warning Symptoms: No dashboard warning indicators occurred immediately preceding the crash. Intermittently, vehicle logs from April 2025 show an electronic control malfunction alert and master warning directing a dealership visit for safety module failure. Manufacturing data confirms a known defect loop where lane-assist features toggle back on automatically, overriding active driver deactivation.

While making a left turn in my 2026 Toyota RAV4, the vehicle's Automatic Emergency Braking / Pre-Collision System suddenly activated without cause. The system sounded an audible warning beep and forced the vehicle to brake and come to a hard stop mid-turn. There was nothing in front of me that should have triggered the system. This put my safety and the safety of other drivers at risk. The forced stop occurred suddenly and unexpectedly while turning, which nearly caused an accident, as vehicles behind me had no warning that I would suddenly brake mid-turn. There were no warning lamps or dashboard messages prior to the incident — the false activation occurred suddenly with no prior symptoms. I have dashcam footage of the incident attached below.

When I put the vehicle in reverse the backup camera is displaying a black screen. I looked up recalls and see there is a recall on RAV4’s for this very issue, but my VIN shows no recalls. I called service at Hubler Toyota in Greenwood IN and they confirmed my VIN is not included in the recall. I want to know why it is not included. I am taking it to Hubler tomorrow for diagnostic and repair. I called Toyota manufacturing to report the incident and was advised to contact the federal safety agency.
