Honda Accord lane assist problems

Filed Oct 29, 2026 · Driver assistance · CA

I was driving steadily on the freeway in slow moving traffic at 20-30 miles and had a lot of distance between me and the car in front. There was a sudden jolt and it appeared the vehicle was attempting to brake unexpectedly. If my foot had not been on the accelerator, I believe the vehicle could have come to a sudden, complete stop, potentially causing the vehicle behind me to rear end my car. Several months, before this incident, the Collision Mitigation Braking System and Lane Assist warning alerts would sound while I was driving on the freeway. This happened at two separate times. The sudden alarms are startling, and I cannot safely read the dashboard messages while driving. I am forced to slow down or pull over to check what is wrong, creating additional safety risks. I have a scheduled appointment with the Dealer this weekend due to the sudden braking however, I've brought this issue up with the service department in the past with the warning lights and they don't seem to have a definitive answer as to what is causing it. I have less than 20,000 miles on this vehicle.

Unknown cause - Heavy Traffic I get all warning lights (idiot) come on. No performance loss but every advisory and caution is illuminated. Tested battery 550amps and regulator was putting out 14 volts so all seemed fine. Check battery terminals and connections, all good. After two days lights go away and everything works fine. When lights and advisory are on, no cruise control, TMPS, lane departure, assisted steering, and anything else in the caution light display doesn't work. Good thing all other aspects of the car work fine. Unable to determine the issue with Why this happens. Seen on line others have had this same issue.

In XXX, the driver assistance and safety systems on my 2025 Honda Accord SE began failing repeatedly. While driving, warning messages would appear for the collision mitigation braking system, lane keeping assistance, adaptive cruise control, and automatic high beams, and these systems would become unavailable. This happened multiple times over XXX and XXX . I took the vehicle to Hugh White Honda in [XXX], four to five times for this problem. The dealer replaced the forward-facing camera twice under warranty, but the warnings and system failures continued after each repair. The dealer was never able to identify or fix the underlying cause. I filed a complaint with American Honda on XXX (case XXX). Because the safety systems on a nearly new vehicle could not be repaired, I traded the vehicle in on XXX, with approximately 17,000 miles. No crash or injuries occurred, but the vehicle repeatedly lost the use of its collision avoidance and lane keeping safety systems in normal driving, and the manufacturer could not repair the defect.

While driving my Honda on a highway at approximately 65 mph after rainfall, I experienced a serious and potentially life-threatening safety failure. Without warning, the steering wheel suddenly became locked/restricted, making it extremely difficult to control the vehicle. At the same time, numerous warning lights and safety-system warnings appeared, including: - Brake system warning - Electric Power Steering (EPS) warning - Vehicle Stability Assist warning - Hill Start Assist warning - Adaptive Cruise Control warning - Lane Keeping Assist warning - Collision Mitigation Braking System warning - Road Departure Mitigation warning This incident occurred while I was traveling approximately 65 mph on the highway and nearly caused me to lose control and crash. The sudden loss/restriction of steering control combined with the simultaneous failure or disabling of multiple driver-assistance and safety systems created an extremely dangerous situation. The fact that this occurred after driving in rainy/wet conditions is also concerning. I have researched this issue online and found numerous reports from other Honda owners describing similar warning lights, steering/electric power steering problems, and multiple safety-system failures, particularly involving Honda Accord vehicles. I am extremely concerned that this may represent a recurring safety-related defect rather than an isolated incident. A steering system that can suddenly become locked or severely restricted while a vehicle is traveling at highway speed presents a serious risk of a crash, injury, or loss of life. I respectfully request that the federal safety agency investigate this issue, review complaints involving similar Honda vehicles, and determine whether there is a common defect involving the electric power steering system, electrical system, water intrusion, or communication between the vehicle's safety-control modules. This problem needs to be investigated before someone is seriously injured or killed.Best regards.

My 2016 Honda Accord Touring has an intermittent failure of multiple Honda Sensing safety systems. The vehicle displays warnings for Collision Mitigation Braking System, Road Departure Mitigation System, Adaptive Cruise Control, and Lane Keeping Assist System. When this occurs, these driver-assistance and collision-avoidance features become unavailable. This is a recurring problem. In August 2023, an authorized Honda dealer diagnosed substantially similar symptoms. The technician documented DTC P2583-87, described on the repair order as “lost comm with the wave radar.” The dealer removed the bumper, tested wiring between the radar and camera, checked radar power and ground, and diagnosed a faulty millimeter-wave radar unit. The Honda dealer replaced the radar assembly with part 36802-T2A-A05 and performed radar aiming/calibration. The repair order states that normal operation was restored. I paid $1,422.08 for the repair and related charges. The problem has now returned and is intermittent. At times all systems work normally; at other times the multiple Honda Sensing warnings appear together and the safety systems become unavailable. I am concerned that a previously replaced and calibrated Honda millimeter-wave radar/safety system has experienced a recurring failure. I am requesting that the federal safety agency review this issue and similar complaints to determine whether a safety-related defect exists.

Subject of Complaint: Sudden, simultaneous failure of critical safety and driver assist systems originating from an electronic sensor/control module failure inside the electronic power steering (EPS) gearbox. Description of Safety Hazard and Dashboard Indicators: While operating the vehicle, the Driver Information Interface (DII) suddenly illuminated with multiple critical safety faults simultaneously. The primary indicator was the amber Electric Power Steering (EPS) System Problem warning light (steering wheel icon with an exclamation point). Due to the electronic architecture of the vehicle, the loss of reliable data from the steering gearbox caused a cascading failure across the Honda Sensing safety suite. The dashboard displayed a sequence of distinct system errors, explicitly disabling: Lane Keeping Assist System (LKAS) Problem Road Departure Mitigation System Problem Adaptive Cruise Control (ACC) Problem Safety Risk to Occupants: The unexpected failure of the EPS system immediately compromised the vehicle's handling characteristics, significantly increasing the steering effort required to control the vehicle. Furthermore, the simultaneous and total disabling of the Lane Keeping Assist, Road Departure Mitigation, and Adaptive Cruise Control systems unexpectedly stripped away active crash-avoidance features. This sudden degradation of vehicle control and driver-assist capabilities creates an immediate, severe collision hazard on public roadways.

In my 2015 Honda Accord. The ABS, adaptive cruise control, vehicle stability assist, power steering, lane departure warning, forward collision warning, traction control, hill start assist, and brake system dash lights have all been intermittently coming on and off starting right around 150k miles. Now all of the lights have been on for some time now. I spoke to AutoNation Honda and Chapman Honda here in Tucson and both dealerships said it was a known VSA module issue with Honda. One quoted a $3,700 fix while the other estimated the job to be about $3,800. Technicians at AutoNation Honda confirmed that my Accord has the 32-11 ABS Solenoid Valve Malfunction, and the 85-01 VSA Module Malfunction codes that are directly related to the weak solder used by Honda on these modules. It’s unbelievable that this has been a known issue with Honda’s VSA/ABS modules, and nothing can be done because the cars regular brakes can still be used. This issue directly affects almost every safety function this car came with. Everything is disabled. It’s really unfortunate that this known issue can be labeled as normal wear.

I own a 2023 Honda Accord Touring Hybrid. At approximately 42,000 miles, all of the warning lights illuminated while driving. The warnings included Adaptive Cruise Control, Forward Collision Warning, Lane Departure Warning, Blind Spot Warning, Parking Collision Warning, and multiple other system alerts. At the same time, I experienced a loss of electric power steering assist, increased steering resistance, and clicking/popping noises coming from the steering rack. The Honda dealer diagnosed the vehicle with a failed Electric Power Steering (EPS) steering rack and quoted nearly $5,000 for the repair. A critical steering component should not fail at such low mileage. This is a serious safety concern because the failure affects the driver's ability to safely control the vehicle. Similar steering components have been recalled on other Honda models, but the 2023 Honda Accord has not been included. I believe this defect should be investigated before it results in crashes or injuries.

This event occurred after a history of ABS system issues as well as Infotainment system issues since 10k miles. During morning commute at approximately 60 mph, all dash warnings began to chime associated with the Touring features of the sedan. TPMS, Collision Avoidance, Braking System, Lane Departure, etc. AND Electric Power Steering. The steering wheel clicked and immediately became difficult to steer. I found a safe pullover point and managed to return the car safely the short distance home.
