My 2022 Honda Pilot developed an intermittent failure of the multipurpose forward camera used by the Honda Sensing system. Multiple dashboard warnings appeared simultaneously, including Adaptive Cruise Control (ACC), Lane Keeping Assist (LKAS), Collision Mitigation Braking System, Road Departure Mitigation, Auto High Beam, Blind Spot Information, and a Brake System warning. The vehicle’s normal brakes continued to function, but the affected driver-assistance and collision-avoidance features became unavailable. A Honda dealership diagnosed DTC U3000-49, documented as an internal failure of the multipurpose camera, and recommended replacement and aiming/calibration of the camera. The quoted repair cost was $2,356.95 plus tax. The failure is intermittent. On one occasion, all warning lights disappeared after starting the vehicle and the Honda Sensing safety features operated normally. After the vehicle was shut off and restarted, the warnings returned and the safety features were again unavailable. Honda declined my request for goodwill assistance and advised that this is not considered a known camera problem. I am reporting this because failure of a single camera disables multiple collision-avoidance and driver-assistance safety systems. I am concerned that other 2022 Honda Pilot owners may experience the same U3000-49 multipurpose-camera failure.

My 2022 Honda Pilot Black Edition (VIN [XXX], 62,900 miles) has multiple intermittent safety‑critical failures involving the transmission, acceleration, adaptive cruise control, and HVAC blower. These issues occur without warning and without diagnostic trouble codes. Transmission/Acceleration Failure: Most recent incident was XXX on Highway 71 during heavy traffic. The vehicle twice experienced rapid deceleration with no ability to reach a safety stop. RPM dropped below 1000, then spiked to 6,000–8,000 while the vehicle continued to lose speed. Acceleration returned only after several seconds. This also occurs during highway merging and uphill acceleration. Additionally, when disengaging cruise control and immediately pressing the accelerator, the vehicle loses speed, RPM drops abnormally low, then spikes before power returns. Adaptive Cruise Control/Honda Sensing Failure: On XXX the vehicle rapidly decelerated when a semi‑truck was beside me, despite no vehicle ahead. The week prior, while driving several states away, setting cruise at 70 mph caused sudden deceleration and cruise resetting itself to ~54 mph. These events resemble phantom braking and radar mis‑targeting. HVAC Blower Failure: During a long multi‑state trip the week prior, the AC blower (speed 3–4) intermittently stopped blowing for several seconds, then resumed at the same speed with no change to the display. These failures affect powertrain, forward collision avoidance, vehicle speed control, electrical systems, and cabin equipment. The dealership (Roush Honda, Westerville OH) cannot replicate the issues and reports no stored codes. These defects pose significant safety risks.

Windshield cracked majorly after being hit by a small rock on the highway. Even after having it replaced and the camera recalibrated, 7 safety warnings of the ADAS come on. Reportedly, the frontcamera has failed, which is concerning in a car that has less than 50k and is just about 4yrs old. I believe this is a larger issue, the windshield truly should not have broken that easily and the camera failing so soon is problematic. It is also a very expensive fix.

“The vehicle experiences phantom braking while driving, where the Collision Mitigation Braking System (CMBS) activates without warning even when there are no vehicles or objects in front of me. The vehicle suddenly brakes on its own, creating a major safety hazard and risk of rear-end collisions. The issue has happened multiple times during normal driving at different speeds. Warning lights related to the collision mitigation system and passenger airbag system have appeared intermittently. The blind spot monitoring system has also failed to properly detect nearby vehicles at times. The vehicle was previously taken to the dealership/service department and remained there for an extended period for inspection and attempted repairs, but the problem was not fully corrected. After getting the vehicle back, the same symptoms and braking issues continued. This issue puts myself, my passengers, and other drivers at risk because the vehicle may suddenly brake unexpectedly in traffic.

My 2022 Honda Pilot failed to engage Drive after reversing, despite the Drive button being pressed. This resulted in an unintended backward motion & a collision with another vehicle. 1.What component or system failed or malfunctioned…? The Electronic Transmission Shift-by-Wire system (push-button shifter) failed to respond to a gear change request. Additionally, related electrical systems including the dashboard infotainment system & the integrated USB charging ports have malfunctioned. The vehicle & its components are available for inspection upon request. 2.How was your safety or the safety of others put at risk? The vehicle experienced unintended motion. While attempting to move forward in a parking lot, the vehicle remained in Reverse despite selecting Drive. This failure led to a low-speed collision with a truck’s tow hitch. This defect creates a high risk of crashes, injuries to pedestrians, or property damage because the vehicle does not move in the direction the driver has selected. 3.Has the problem been reproduced or confirmed by a dealer or independent service center? The vehicle was previously serviced at a Honda dealership for a radio/infotainment recall. Since that service, the transmission has failed to engage Drive multiple times at random. 4.Has the vehicle or component been inspected by the manufacturer…? The vehicle was inspected during the initial recall fix. And brought back because after the fix because the charging port stopped working/continued screen glitches. Following the recent collision, it is awaiting further inspection by a Honda dealership to determine the extent of the mechanical failure. 5.Were there any warning lamps, messages prior…? Symptoms began after the recall fix & included intermittent electronic failures of the charging ports/screen. There were no specific transmission warning lights prior to the gear selection failure; however, the persistent electrical issues in the dash area suggested a systemic electronic malfunction.

I turned my car on one day and warning lights for all of my safety sensing features came up. Intermittently they work for a little bit. I brought it to the dealer, and they said that there was damage to the sensor, but there has been no damage to the front end of the car. Their reply was perhaps a pebble came up from the road while I was driving. It seems to me that that is a fault in the manufacturing if it is that easy for all of the sensing features to stop working. I attempted to sort this out with the dealer and with Honda corporate offices with no luck.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy.
