An internal failure on the front windshield camera assembly part #36160-TG7-A63 had caused the Advanced Driver Assistance Systems to fail. Which in turn has caused the following systems to fail: Adaptive Cruise Control, Automatic Emergency Braking, Blind Spot Warning, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance, Parking Collision Warning, and Rear Cross Traffic Warning. Leaving these systems unrepaired due to a known and common hardware failure issue leads to this specific vehicle and the ones similar unsafe for the driver and occupants due to the safety systems being inoperable. The problem has been confirmed on two separate occasions by my local Honda dealer. The known issue with this specific camera assembly leads to a multitude of warning lights being displayed including: adaptive cruise control warning, lane keep assist, collision mitigation system problem, and auto high beam mitigation.

On or about January 7, 2026, we were driving through town and the dash cluster lit up with five separate warnings for safety features no longer operational. These are adaptive cruise control, lane keeping assist, collision mitigation, road departure mitigation, and automatic high beams. We cleaned the windshield and radar housing. Then the battery was replaced. None corrected the problem. An appointment was then scheduled at the dealership for 1/9/2026. It was determined the multi-purpose camera had an internal short. The only fix is a new camera ($1284) and re-aim process. The total repair cost, not including the $165 diagnostic fee, is $1727. In the meantime, the driver safety features are mostly unavailable, including the traditional cruise control. I say mostly because the system randomly works for a few minutes before overheating/shorting. I worry about fire and sudden emergency braking due to the short. I must note this system has never functioned well. In particular, the camera and/or radar “sees” problems that don’t exist and unnecessarily and repeatedly activates the warning notifications, especially on two-lane highways. I may still have video of a trip where there were dozens of warning notifications within just a few miles for cars in their own lane. The collision mitigation system has been off for nearly all our ownership as it nearly caused a major accident on our second day. As I was accelerating up to highway speed to merge onto the highway I activated my turn signal. A truck in the driving lane was slowing to let me in, however, the system saw traffic in the vicinity and activated numerous warnings on the dash while simultaneously activating the brakes and steering me towards the ditch. The car behind me had to panic brake to avoid hitting me. I had limited driver input during this period but was able to get stopped on the shoulder of the highway. I liken the Honda Sensing system to a 16 year old driver who is prone to panic.

I am reporting a safety defect in my 2020 Honda Pilot EX-L ~86,300 miles. The rearview camera and electrical/infotainment system intermittently fail, showing static, disconnecting Bluetooth, and sometimes leaving the camera blank. This creates a serious safety risk when reversing, driving in tight spaces, or transporting my children. These issues began within the first year of ownership (2020–2021) and continued after Recall 23-047, during which cables were replaced and the system later rewired in August 2023. Despite these repairs, the defects persist. The dealership Pohanka Honda Fredericksburg confirmed the faults multiple times but now refuses to repair, quoting over $3,000. The vehicle has also experienced three dead batteries since 2020, leaving me stranded multiple times, including once during out-of-state travel. There were no warning lights for the battery failures, but infotainment and camera issues were noticeable immediately. The vehicle has been out of service for approximately three cumulative months, impairing reliability and my ability to perform daily work and family responsibilities. These defects have significantly impaired the use, value, and safety of the vehicle, especially given my responsibilities as a single mother, caregiver to a blind parent, and emergency department practitioner. The vehicle has been inspected by the dealer and reviewed by Honda corporate. I am seeking a proper remedy for a federally mandated safety feature (rear camera, FMVSS 111). The vehicle and affected components are available for inspection upon request. This complaint documents ongoing safety risks, repeated battery failures, and unresolved recall-related defects that began under warranty. Honda’s failure to properly repair these defects continues to create unsafe driving conditions and a serious risk of injury to myself, my passengers, and the public.

From what dealer said these are common problems with this vehicle, should definitely be part of a recall. Wanted 3000. to correct issues.

Lane Assist Camera Failure (Part #36160-TG7-A63) Vehicle Information: Make/Model/Year: 2020 Honda Pilot EX-L Failed Component: Lane Assist Camera, Part #36160-TG7-A63 Safety Issue Description: The lane assist camera has failed, disabling multiple critical safety systems, including: Adaptive Cruise Control Lane Keeping Assist Collision Mitigation Braking System Road Departure Mitigation Auto High-Beam System Concern: This camera component is not subject to normal wear and tear, being housed within the vehicle's protected interior near the rearview mirror. The failure of this part represents a potential manufacturing defect that compromises essential safety features designed to prevent accidents and save lives. The simultaneous loss of multiple Honda Sensing safety systems creates a significant safety hazard, particularly given that drivers rely on these systems for collision avoidance and lane departure prevention. This premature failure suggests a systemic defect that may affect other 2020 Honda Pilot vehicles. Request: I request that NHTSA investigate this matter for potential safety defects and consider whether a recall is warranted for affected Honda Pilot vehicles with this camera component.

I own a 2020 Honda Pilot EX with approximately 58,000 miles. Every time I drive on two-lane roads, I receive a bright orange “Brake” warning from the Automatic Emergency Braking system when vehicles in the opposite lane are passing by. The system falsely detects an imminent collision, even though the oncoming vehicles are safely in their lane. The system then applies the brakes unnecessarily. Most of the time it brakes mildly, but on at least two occasions it has braked very hard, causing the vehicle behind me to nearly rear-end my car. This creates a significant and dangerous situation, as it could easily cause an accident. I now have to disable the automatic braking system every time I drive. During my last drive, after disabling the system, I received a warning message stating: “ABS Failure — Take to Dealer.” I have also experienced dangerous behavior from the Lane Departure Warning/Assist system. When exiting the freeway, if the lane lines disappear or become unclear, the vehicle has slammed on the brakes suddenly. On one occasion, this caused me severe whiplash. Thankfully, I was alone in the car — if my young children had been passengers, they could have suffered serious neck injuries. I have taken the vehicle to the Honda dealer and independent mechanics. Each time, they have only cleared the codes and told me it was due to “dirty sensors.” The warnings and braking issues, however, keep coming back. This issue is persistent, reproducible, and unsafe. The Automatic Emergency Braking, Lane Departure, and ABS systems are not functioning properly and create a real danger to myself, my passengers, and other drivers on the road.

PE25008 · Engine Failure

Opened Aug 20, 2025 · No close date supplied

Status: open (inferred from source dates) · Engine

The Office of Defects Investigation (ODI) has received 414 reports of connecting rod bearing failures in the 3.5L V6 engine used in the following vehicles: Model Years (MY) 2018-2020 Acura TLX, MY2016-2020 Acura MDX, MY2016-2020 Honda Pilot, MY2018-2020 Honda Odyssey, and MY2017-2019 Honda Ridgeline.  The subject engine failures were analyzed as part of a Recall Query (RQ24013).  It was determined that these engine failures are outside the scope of Honda Recall 23V-751. Further, evidence gathered in conjunction with RQ24013 does not suggest this failure is caused by the same crankshaft manufacturing defect that is addressed by Honda in Recall 23V-751.  Based on analysis of data from RQ24013, NHTSA has closed that investigation. The significant number of reports of engine failure in vehicles outside the scope of RQ24013 presents a potential safety risk that warrants further investigation.  ODI is opening this Preliminary Evaluation (PE) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues.  To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

RQ24013 · Engine Failure

Opened Nov 8, 2024 · Closed Aug 20, 2025

Status: closed (inferred from source dates) · Engine

On November 8, 2024, the Office of Defects Investigation (ODI) opened Recall Query RQ24013 to assess the scope of Honda recall 23V-751 after receiving complaints that alleged connecting rod bearing failures in vehicles that were not within the scope of recall 23V-751. In November 2023, Honda recalled 248,999 various Model Year (MY)2016–2020 Honda and Acura vehicles equipped with the 3.5L V6 engine. Honda recalled these vehicles due to a crankshaft manufacturing defect that caused premature connecting rod bearing wear and engine seizure. While the out-of-scope failures involved in these complaints appear to have a very similar failure mechanism as the recalled engines, a thorough analysis of all available data from Honda has not indicated that the same manufacturing defect exists in the out-of-scope engines as the engines recalled by 23V-751. Based on this analysis ODI has determined that Honda has properly defined the scope of recall 23V-751. Consequently, ODI will close this RQ investigation.  NHTSA will continue to investigate these complaints of engine failure as part of a new Preliminary Evaluation Investigation (PE25008). The Agency reserves the right to take additional action if warranted by new circumstances.
