Toyota RAV4 adaptive cruise problems

Filed Nov 5, 2026 · Acceleration, Brakes · CA · crash

On August 28, 2026 at about 8:00 AM, while maneuvering into a parking space at under 5 mph, my vehicle suddenly accelerated and I was unable to stop it before it struck a tree. Adaptive cruise control was off; lane keeping assistance was on, as it normally is. I attempted to brake, but the vehicle did not stop, and automatic emergency braking did not engage before impact. I do not recall any warning lamps or symptoms beforehand. A neighbor witnessed the incident. The vehicle is available for inspection. Toyota inspected the vehicle on September 5, 2026. Its letter states that the EDR readout showed accelerator pedal pressure and no brake pedal application before impact, and that it found no defect. These findings do not match my recollection, and I have asked Toyota in writing to verify them. Toyota’s letter also lists the wrong incident date (August 5, 2026), so I have requested the complete EDR report and confirmation of which stored event was read. I will update this report when I receive it. My spouse experienced a similar sudden acceleration symptom in the same vehicle on May 19, 2026, with no collision. It was not reported at the time.

What component or system failed or malfunctioned, and is it available for inspection upon request? The concern involves the vehicle's Toyota Safety Sense (TSS) active safety systems, specifically Lane Tracing Assist (LTA), Steering wheel assistance and the Pre-Collision System (PCS) with Dynamic Radar Cruise Control (DRCC).The suspected systems/components involved include the forward-facing camera, front radar sensor, steering assistance/LTA system, and related ADAS software calibration. The vehicle is available for inspection upon request. The issue is with system performance during operation, not a visible physical component failure. How was your safety or the safety of others put at risk? While driving on highways or non-highways with clear lane markings and LTA/DRCC activated, the vehicle has shown inconsistent lane-centering behavior. The vehicle can weave within the lane and has drifted toward an adjacent lane without intentional steering input from me. This creates concern about unintended lane departure and reduced driver confidence in a safety assistance feature.I also have concerns regarding the Pre-Collision System's ability to detect stopped vehicles ahead early enough to provide appropriate warning or automatic braking intervention. A delayed response from an active safety system could increase the risk of a collision. Has the problem been reproduced or confirmed by a dealer or independent service center? I have reported the concern to the Longo Toyota dealership multiple times in Prosper, Texas. The dealership inspection identified. However, to my knowledge, the dealer has not successfully reproduced or documented the specific driving conditions required to observe the issue (highway or non-highway driving with LTA/DRCC active) with me present. The issue continues after the service visit. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Only Toyota Dealership inspected No warnings displayed .

Within the 1st year I purchased it new, I would get a warning that the RSA is malfunctioning. It seems to happen when I park in the sun and the windshield is very hot. The warning in my dash prevents me from seeing my other readings; mph, fuel, and I can't use my other safety features; LDA, PCS or cruise control. I've taken it in but then it does a reset and the technicians say there's nothing wrong. The warnings happen every month, weekly. I just got tired of taking it in to hear they don't see anything wrong!

Before o had taken my RAV4 into Toyota for the recall a AAA tech. had replaced the battery after jump starting it. There was nothing wrong with the sensors or anything else but after the battery was replaced all the electric sensors that are for lane change warnings and cruise control etc. stopped working. I took vehicle into Toyota of Santa Maria and was told that I needed to pay for the sensors that had failed. They told me that I was responsible and I do not believe I am when AAA had just replaced my battery and only after that did the sensors have an issue. I do not feel safe driving my car now because all the sensors aren’t working anymore.

I purchased a 2024 Toyota RAV4 in March 2024 with the expectation that its advertised safety and driver-assistance systems would function as designed. The vehicle has experienced a failure of the forward camera/ADAS system, resulting in the loss of multiple Toyota Safety Sense features. The following systems are currently unavailable or malfunctioning: • Dynamic Radar Cruise Control / Adaptive Cruise Control • Pre-Collision System • Lane Tracing Assist / Lane Keeping Functions • Road Sign Assist (speed limit recognition) • Related driver-assistance and safety warning functions When cruise control is activated, the vehicle displays a warning that cruise control is unavailable. The dashboard reports multiple safety-system malfunctions. As a result, I have lost essentially all advanced driver-assistance features that were included with the vehicle. Toyota’s dealer diagnosed the failure and Toyota approved the repair under a goodwill case. However, I was informed that the required replacement component is on national backorder with an estimated wait of approximately two months and no guaranteed delivery date. Despite acknowledging the defect and approving repair, Toyota has not provided a comparable loaner vehicle or alternative transportation. I am being asked to continue operating the vehicle for an extended period without the safety technologies that were a significant factor in my purchase decision. I am concerned about the loss of collision-avoidance, lane-assistance, and adaptive-cruise functions, the indefinite repair delay, and the lack of transportation assistance while awaiting parts. I am requesting investigation, assistance, and consideration of repurchase or other appropriate remedies.

2 incidents of Sudden Unintended Acceleration. No warning lights etc in either. Car damaged but available for inspection. Now encountering difficulties initating Toyota investigation. 1st incident (4/18/25; mileage 967) occurred after a hard left turn. After turn onto uphill street, I took my foot from accelerator to slow and maintain distance from a car backing down hill ahead. Instead, car self-accelerated and shot uphill, over speed bump with increasing speed. Did not respond to braking until it was close to hitting a parked car. Stopped with a slam; probably brake assistance engaged. No damage or injury, but I was shaken. Took car immediately to Toyota dealer to inspect. Was told RoB confirmed an event but not its nature or cause; identified nothing wrong. They hypothesized cruise control might have been triggered accidentally (no evidence, not plausible). Claimed they submitted report to Toyota national center. After 2nd incident, Toyota national said they had no record of 1st event. Their standard safety inspection protocols were not followed. Returned car to me without repair or follow up. 2nd incident ensued. 2nd self-acceleration event (2026) also occurred after hard left turn to make U turn at low speed, braking while completing turn. When I took my foot off brake, before I could press it on accelerator, car shot diagonally across street. Jumped curb and traveled at considerable speed 100' up landscaped slope. Destroyed 6 large shrubs and 3 trees 9' tall. Did not stop despite constant driver braking. Forward collision prevention system did not engage to prevent uprooting trees. Car stopped only after I turned steering wheel sharply to left to avoid hitting a full-size tree trunk. Then car responded to braking, acceleration ended, car stopped next to tree without impact. Terrifying life-threatening event but only damaged landscape and car. Police came, assessed incident, determined not a police matter, did not file police report.

My Toyota hybrid AWD vehicle experienced corrosion of the rear traction motor cable, which Toyota has acknowledged in Service Campaign 25TD01. This corrosion affects the electrical connection to the rear drive motor and can result in loss of AWD propulsion capability. Loss of rear-wheel propulsion significantly reduces traction and stability, particularly in snow, ice, and wet conditions. Drivers may believe the vehicle still has AWD capability when in fact the rear drive system is compromised. In addition, the vehicle’s adaptive cruise control system repeatedly turned off unexpectedly while driving and displayed “unavailable” warnings. These malfunctions occurred alongside the electrical issues related to the rear traction motor cable corrosion, suggesting the defect may affect multiple vehicle systems. Toyota has acknowledged this defect through Service Campaign 25TD01 but has not issued a safety recall. Given the potential for loss of propulsion and malfunction of driver-assistance systems, this issue should be investigated as a safety defect.
