2021 Honda Pilot driver assist problems

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

My 2021 Honda Pilot displayed a U3000 diagnostic trouble code, indicating an internal electronic failure of the front-facing multipurpose camera that operates the vehicle's Honda Sensing safety systems (Collision Mitigation Braking System, Lane Keeping Assist System, Road Departure Mitigation, and Adaptive Cruise Control). As a result, these safety systems became inoperative. I took the vehicle to an authorized Honda dealer, who confirmed the U3000 code and quoted approximately $2,000 to replace the camera unit. I have since learned this is a widely reported failure across multiple Honda and Acura models (Pilot, Odyssey, CR-V, Accord, Civic, HR-V, Clarity, RDX, MDX) and is the subject of a proposed class action lawsuit alleging Honda knew of the defect and failed to disclose it or issue a recall. I am filing this report to document the failure and its safety impact.

LANE DEPARTURE: WARNING

The vehicle’s driver‑assist and collision‑avoidance systems began failing simultaneously. Multiple warnings appear on the dashboard every time the vehicle is started, and the cruise control system has stopped functioning entirely. Adaptive Cruise Control cannot be disabled, preventing the use of standard cruise control. Collision Mitigation System Problem Adaptive Cruise Control Problem (ACC) Lane Keeping Assist Problem (LKAS) Road Departure Mitigation System Problem Auto High-Beam Problem The failure of one component impacts multiple vehicle features, the ability to maintain safe following distance, avoid collisions, stay within lane boundaries, and properly manage headlights. The loss of cruise control functionality also affects long‑distance driving safety and consistency. These systems are designed to prevent accidents; their simultaneous failure represents a significant safety hazard. Dealer inspection indicates repairs costing thousands of dollars, often involving replacement of sensors, radar units, or wiring harnesses. No recall or service bulletin has been provided to address this widespread issue. Many Honda owners have reported identical failures on online forums and owner groups. The pattern suggests a systemic defect affecting Honda’s driver‑assist safety systems across multiple models and years. I am requesting that NHTSA investigate this issue as a potential safety defect affecting Honda vehicles. The failure of multiple collision‑avoidance and lane‑keeping systems at once poses a serious risk to drivers, passengers, and others on the road.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

My Honda has recently began displaying ADAS Failure where none of the features work including cruise control. I took to a mechanic and they displayed code U3000. This seems to be a common issue that Honda is not addressing. The fee to repair is over $1500 and the car is less than 5 years old. This is a safety issue.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

While driving down the road the emergency braking turned on many times when I wasn’t even near a vehicle. It turned on about a total of 10 times without a car being unsafely in front of me. I just got this vehicle today and I’m worried about whether I should keep it or not because of this.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

About a month ago, I started my Pilot and the dash lit up. The adaptive cruise control, emergency braking, lane keeping assist, Lane departure, forward collision warnings all flashed on the dash- no previous warnings. Subsequently, the cruise control will not work at all. I had the system scanned by a Honda certified mechanic and it showed and internal cameral failure. This is a known issue across many Hondas and is a very costly repair at close to $2000.

LANE DEPARTURE: WARNING

I purchased my Honda Pilot 2021 5 years ago. Currently still making payments on it. The Collison Mitigation system warning sign came up on my dashboard about 1 year ago. After that warning sign came on 4 others popped up. Road Departure Mitigation system, Auto high-Beam problem, Adaptive cruise control problem, and lane keeping assist problem. Having all these warning signs come pop up on dashboard is very distracting while driving. Non of these controls are working and I have taken it to Honda to do an inspection. Since, its out of warranty I have to pay out of pocket $2,137.63 to get multipurpose camera unit replaced. Let alone this vehicle is still not paid off. I've also had issues with the starter shutting off while driving. It had a recall and I did get it replaced but I'm still having issues. This is a serious safety problem due to it shutting off while on the street. I been in life threating situations due to this problem. Honda needs to make sure there vehicles are safe for customers.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING

Infotainment system doesn't work, including maps, and backup camera. I have read this is a common problem, but Honda isn't doing anything about it.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

Braking system and cameras defective. Vehicle will flash BRAKE when nothing is in roadway. This will also cause vehicle to hard brake. When on interstate, cruise control no longer functions properly due to camera sensors reading a vehicle is in front of my vehicle when there is no other vehicle near. This causes braking system to activate and/or slow the cruise control down. This is a major safety risk for everyone involved, especially my children in the vehicle. This is a known Honda issue. This needs remedied before someone gets hurt and a lawsuit ensues. Fix the braking system and cameras!
