Assist problems of the 2021 Honda Pilot

Problems started showing on car a week ago. Tested battery and it was not holding a charge. Replaced battery and problem still persisted. Car is now at dealership and they are quoting close to $2000 due to failure for internal windshield camera. Car has right over 78k miles. This is a safety issue.

On multiple occasions the hazard mitigation system has picked up on hazards that aren't there causing rapid braking and steering over correction. Currently the button on my vehicle that has an image representing the ability to turn the system off doesn't appear to be connected or working. I have always left the system on as it felt "safer" when I bought the vehicle new. I haven't even tried to turn it off until recently when the system seemed to start malfunctioning. Today (11/19/2025) while traveling the interstate for a routine doctor appointment the adaptive cruise control randomly shut off as I was driving multiple times. If I changed lanes and a vehicle was in front of me the adaptive cruise control would just shut off with no warning or alert rather than adjust the speed as the system is designed to do. Once I exited from the interstate at a traffic light (green, turning left) the lane assist overcorrected, the steering wheel got stiff and it was jerked into the other lane almost causing a collision. This is very concerning as I was very fortunate not to have been involved in a collision today thankfully the other driver was paying attention and evaded. Each incident there has been zero warning. There have been a couple times recently where the system randomly fails and says there is a problem, but within minutes come right back on and operates properly until it randomly malfunctions again. This has occurred very sporadically over the past 6 months with incidents rapidly increasing over the past 3 days to the point I am very nervous to carry my children in this vehicle any longer. This vehicle was purchased as the primary vehicle for our family and our purchase was strongly influenced by Honda's "safety", but now that's very much in question as I understand many other Honda owners are experiencing the same Honda system issues. We are in the process now of having it scheduled with Honda, but this should not be acceptable from any manufacturer.

Vehicle is setting multiple faults for adas system. Lkas, acc, collision mitigation system, auto high beam lights inoperable. Forward facing camera in the top of the windshield has failed.

Dash warning lights come on for lane keeping assist, collision mitigation, acc, brake system, auto high beam.

The following warning lights: adaptive cruise control problem, lane keeping assist, collision mitigation system, road departure mitigation problem, auto high beam problem. Honda estimates over $2000 to repair? from what I understand there are many other Honda's with these issues! with these items not functioning, it defeats many of the safety features we bought the car for. Exact date of when it began was last summer.

The car's steering wheel got locked out and air bags came out suddenly while car is still moving on the road and driver blocked and not able to do anything and hit the parked car on the street due to car's system malfunction. Since incident happened in the housing community area with speed 20-25 miles and not majorly hit anyone but reported to and inspected by city police inspected. This was the first time this situation happed and however, had other incidents with the car auto feature malfunction, when stop on the red signal and suddenly the card shutdown with lot of beeps. This mentioned to the service center where normally go for servicing activities like oil change etc.

The following warning lights: adaptive cruise control problem, lane keeping assist, collision mitigation system, road departure mitigation problem, auto high beam problem.

All safety/collision prevention systems related to camera have become inoperative. Vehicle will not lane keep assist, emergency brake, or notify of possible collisions. Problem occurs every time vehicle is turned on.

Upon startup, lkas, acc, fcw and brake lights are illuminated and the corresponding systems are non-functional. This failed with less than 50k miles and the car was ~3 years old. This is making the car less safe to drive because some of the safety systems are non functional. The basic cruise control also does not work.

Multiple safety features are failing on this 2021 Honda Pilot. At startup, I get the following errors: collision mitigation system problem, road departure mitigation system problem, adaptive cruise control problem, lane keeping assist problem. Dealership says the camera inside the vehicle needs to be replaced and it will cost $1,800. It looks like many people with similar models are encountering this problem with very young vehicles.

Upon turning on my vehicle all of the emergency warnings came on. I did a diagnostic and was shown that nothing was wrong with the vehicle but the warnings will not reset.

I was traveling with my daughters [xxx] , and [xxx] , in the back seat. It started raining heavy just as I passed a vehicle and returned to the right lane. I reduced my speed, then felt the vehicle hydroplane slightly and felt the traction control system engaged. As soon as the traction control icon displayed, I began to feel the traction slipping and noticed a slight unresponsiveness in the steering. My speed suddenly dropped 15-20 mph, without braking, or any change in pressure on the accelerator. I then tried to accelerate, but was unable to possibly because of loss of traction I noticed the traction light was flashing. The vehicle I had just passed moments before was quickly approaching at roughly 65 mph (speed limit was 70 mph) and had no warning of the issue with my vehicle decelerating, luckily they were paying attention and able to pass safely. When they passed, I pulled off the road and had these warnings on the screen: - collision mitigation braking system. Cmbs problem. - lane keeping assist problem. - road departure mitigation system problem. I placed the vehicle in park, shut it off, then restarted it. The error messages went away, then came back on as soon as I started driving. The traction control light remained off and the rain subsided, but the warnings remained. Dealership is supposed to inspect Wednesday 07/31/24. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Acc, lkas, collision mitigation system problem, road departure mitigation system, and auto high beam problem warnings all appear on instrument panel. None of these systems work. Have replaced battery and problem not fixed. Warnings continue to appear each time car is turned on. Vehicle has 47783 miles on it. Codes indicate there’s a problem with the camera in the front of the car. The car is only 3 years old. Shouldn’t be having these issues. Have researched online and found many other complaints from others from various Honda models. Major safety problem that warrants a recall.

This is new Honda Pilot 2021 trim ex-l purchase in Dec,2020. Miles 3300. It seems Honda is having software issues. Without on of lane keeping assist system (lkas) feature is activating automatically and taking over driving or steering of the vehicle and attempt to steer the vehicle back into the center of the lane. Basically it's giving false indicator without on of lkas feature and due to this issue driver is becoming panic situation this will be safety issue and this will cause problems for others safety as well(putting other at risk while driving). This is appearing from past one week onwards. Called Honda customer care about this issue and informed. They have taken a notes to inform r&d/technical team and suggested to take to service to determine system failed or malfunctioned.
