Forward Collision Avoidance
It is constantly breaking when cars are coming the other way. It almost caused a vehicle to almost hit me. Also the auto shut off has almost caused accidents because it causes my car to stall and I wish I could keep it off and not have to push the button off every time.

While driving on I-26 at 60 MPH at approximately 2PM on 01/08/2026 the sunroof exploded. It was not struck by anything, no other vehicle was within a half mile of us at the time. Fortunately the cover was closed because we do not use the sunroof. It has only been opened one time a the delership the day the car was delivered new. This sunroof explosion was loud and frankly scared the heck out of us. Had the cover not been kept closed we would have been showered by broken glass. This could have easley resulted in a driver panic and a crash. I feel this is a manufacturing defect and based on numbers of events through various Honda models and years should covered by Honda recall/warranty coverage.

Engine fails to restart on its own from a complete stop at a traffic light or road intersection with the Auto Idle Stop (AIS) function engaged. When I release the brake pedal, the vehicle automatically goes into neutral, and when I try to put into Drive, nothing happens, then it takes multiple attempts to turn the vehicle off. Once it turns off, it does turn back on, and I can continue driving. This behavior is hard to reproduce consistently, it's happening from time to time.

As I was traveling from Houma, La on a major highway to an out of state meeting. I started to hear a slight tapping sound and pulled over to inspect the sound. Upon inspection it seemed as though it was coming from the lower engine, or exhaust near the engine area. I located the nearest Honda dealership which was Community Honda of Lafayette with intentions of dealership inspection. It was approximately a 20 minute drive from the current location. As I was approaching the exit to the dealership the warning system lit up an check engine light. The Manager at the dealership took the vehicle to the back and ran a scan and responded that it sounds like an exhaust leak. I got back on the road for my destination. Approximately an hour later while I was on [XXX] all of the warning lights lit up at once, the engine jerked and shut off. I pulled over to inspect the vehicle again. I restarted the vehicle to work myself to a safe exit. The vehicle would not drive over 20mph. Once at a safe location I made concessions to have the vehicle carried back to my local Honda dealership, Barker Honda in Houma, La Upon inspection by the Honda technicians it was found to have irreparable damage to the engine internals. Technician states this could occur to low oil and/ or lack of maintenance; however, the technician was perplexed by the failure because all maintenance and records in their system showed that the vehicle was properly maintained by their staff.

The ADAS camera has failed. It is extremely common. When it fails, all the lights for EVERY system of ADAS comes on. None of them work. And it is not possible to turn off. Furthermore it sets codes for the brakes and turns on the brake warning lights. So none of the brake assist systems work either. Honda refuses to warranty any of these systems when the camera fails. It is across their entire line of vehicles with ADAS. If they can’t build a functional system, it should not have the system. Also, the system functions extremely poorly, when it was operating. It will drive the vehicle, unassisted, down to 20 mph, then just shuts off and lets the vehicle coast, unguided. Also, if the cruise is set and lane keeping on, and it can’t find lane lines, particularly where lanes merge, it will often veer left, into oncoming traffic. I have tested both of these, when the system was functioning “correctly”. The cruise and lane keeping just shuts off, at any speed, and lets the car go where ever it would without input. It is extremely dangerous.

Every since I purchased my 2022 Honda Pilot, I have had soo many issues with the windshield chipping. I bought the car brand new. Within the first 6 months, I had a chip at the top right corner (passenger side) the ended up cracking all the way to the edge. I had to replace the windshield. Fast forward to within a year of the new windshield being in place, and I know have FOUR chips. All on the passenger side. Two near the bottom and two near the top right. I have asked Honda several times if there are issues with the windshields, and they claim there is not. I have asked about having my frame checked to make sure it wasn't a manufacturing issue, but have not, since they need the windshield off to look. I have been driving for over 20 years. I have NEVER had a chip in my windshield. I even had a 2018 Pilot - 0 issues.

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. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.
