general problems of the 2016 Honda Pilot - part 1

Following all repair/recall/warranty work recommended by Honda, the auto stop/start feature is again failing. This results in the vehicle not restarting after the auto idle engine stop is engaged while in traffic, stop lights, stop signs etc. This is a random occurrence, but results in a significant safety hazard as a stopped vehicle in a lane of travel. This is a recurring issue, no specific date of incident.

When the vehicle idle is on and I break at a red light or stop sign it has not started back up. This has happened a few times. Today at a red light it cut it did it and I needed a jump start to get it back working.

Honda issued service bulletin 20-117 regarding a warranty extension for the 2016–2017 Pilot and 2017 ridgeline addressing a keyless start system error with dtc b12c5. Following an NHTSA investigation, Honda extended warranty coverage to 9 years or 125,000 miles under this bulletin. My 2016 Honda Pilot currently has 107,000 miles and is only six months past the nine-year time limit. Earlier this year, the keyless start system warning indicator began appearing intermittently—illuminating for a few seconds before disappearing for days or weeks. Recently, the warning began to stay on continuously. Per Honda’s initial guidance, I replaced the key fob battery and even swapped fobs with my wife, but the issue persisted. On October 16th, I brought the vehicle to Honda of chantilly, where technicians diagnosed a faulty start/stop button requiring replacement. I then opened case #15920037 with Honda, but they declined to cover or reimburse the repair, despite it being a known defect covered under the extended warranty for others. I respectfully request that the NHTSA assist in having Honda honor the warranty extension for this documented issue, given the close proximity to the coverage limit and the long-standing nature of the defect.

Engine developed noises while driving and seized up. Prior to engine seizure, auto start/stop was having issues where it would not restart after stopping at a light or stop sign. Rear unibody rusting really badly due to cheap quality metal?.

The engine shuts off while driving and the car shifts the transmission to park or neutral.

My 2016 Honda Pilot has continued to have engine restart issues with the automatic engine stop feature after taking it in for the initial recall. Upon telling this to the dealer, they said the recall work was already done and won’t address it further. They only did the software upgrade and did not tell me about the 2nd stage of repairs available. The issue is random but happens commonly, and seems to be worse on hot days. It also can sometimes struggle to restart after putting it in park after the auto restart fails.

The fuel injection system routinely fails or misfires. Not only does this cause an issue with said system but it also triggers a host of other dashboard alerts. The alerts display all wheel drive problem, emission system problem, power steering problem, hill start problem, vehicle stability assist problem. This is a safety issue because the amount of alerts especially unrelated alerts is obfuscating any actual problems and making it difficult to diagnose the real issue. Investigation shows many other drivers having the same issues with this model only going away when the fuel injection system is replaced. It's also safety issue because if the fuel injection is failing then the car may shut off at a danger to the driver and the public. Given that it is known and chronic it should be a recall.

My battery was being drained until dead by a faulty keyless control module. I paid to have the battery replaced after my son and I got stranded 1. 5 hours from home. All the lights on the dash went off and nearly every error code displayed as well. Currently at Honda dealership getting the module replaced at a mere $840 after I paid $370 for battery installation when my car "broke down". Now to see I am not the only Honda customer with this issue in this model of vehicle. The car started displaying all the error codes about a week before it began just completely draining the battery that was on 6/23. Battery replaced that day and by Saturday 6/28 was unable to start my car due to battery being completely dead. Had to jump my car and take to dealership on Sunday 6/29. So was late to work and have been without my vehicle for over a week while they were trouble shooting the issue.

In my 2016 Honda Pilot a lot of buttons are popping up on the screen with no information about how to fix it. My car is having trouble accelerating and is hesitating when needing to accelerate. I was unable to speed up while driving to get to 45 mph because it would not speed up. All the buttons that are coming up on my car or not correct it’s showing trailer issues and I’ve never once trailed anything with my car. It seems like it’s having extra trouble when the air condition is on as well. I’m unable to figure out what is wrong with my car because all the buttons are not coming up correct when they plug it in for a diagnostic. I have had the alternator replaced and that did not change anything.

Car sound system distort and no sound after 10 minutes of driving. No bluetooth audio, radio, music working. Changing volume, sound setting, factory reset the info system but the problem still exist. Increase the a/c fan speed and driving through pumps seems make the problem start earlier. Sometimes, turn off the car and restart the car after 30 minutes, the sound system is back on, but after the 10-15 minutes the sound went off again. This problem could cause safety issue as I relied on navigation sound while driving. There seems to be the same problem that being recalled in newer model.

Check engine light on emissions system problem and transmission system problem, there is loss power of engine light, after 2 gear transmission feel like it jerks I don't have save to drive my car, I would like to request a recall to be inspected and repair by warranty of Honda because my car is defective by manufacturer code are: p0420 (rear bank catalyst system efficiency below threshold [bank 1]) p0430 (front bank catalyst system efficiency below threshold [bank 2]) p0300-p0306 (misfire) p219a (air-fuel ratio variation of cylinder [bank 1, rear bank]) p219b (air-fuel ratio variation of cylinder [bank 2, front bank]).

The contact owns a 2016 Honda Pilot. The contact stated while driving approximately 40 mph, the lane departure, adaptive cruise control, and two additional warning lights were illuminated. The contact stated that the blind spot system and cross-traffic warning lights illuminated. The contact stated that the start/stop button failed to start the vehicle. The vehicle was taken to the dealer who diagnosed the vehicle and determined that the multi-purpose camera and all safety system features, and the start/stop system had failed. The vehicle was not repaired. The manufacturer was made aware of the failure. The manufacturer confirmed that the repair was not covered under recall or warranty. The failure mileage was approximately 60,000.

Auto start/stop not working at stop. Vehicle fails to restart when engine has turned off at intersection. On occasion, vehicle fails to start and loses total power. Often, it takes several minutes to regain power. This has occurred in intersections, almost causing accidents. The car was repaired per a TSB, but the issue continues, and has for the last 4 years since purchase.

Ecm failure with fuel rail/system pressure code. Safety issue due to no prior issue and all of a sudden engine stalling in the middle of a busy intersection and taking 10 mins to get started and shift gears to get out of the way of oncoming traffic with all dashboard lights illuminated to include check engine light, trailer stability assist problem light, hill assist problem light, lkas light, and acc light.

Vehicle was fixed for auto start stop under recall. They changed all the parts including capacitors. Within 5000 miles it started happening again. I’ve informed Honda about this from 20k miles. The vehicle now has 165k. I’ve told them on multiple occasions that this is a serious safety issue. They said they have this fixed and they do not. They closed my case even though I asked them to keep it open as they have not proved to me that it is fixed. The only way to fix this is to have Honda program the care to not allow start stop as someone is going to get killed. It’s just a matter of time.

The car has trouble starting. It has been occurring for years. (1) it cycles like it has a bad battery. (2) it cycles like the starter is not getting power or is bad. (3) sometimes this causes the engine starting cycle to completely fail and restart is not immediately possible. (4) the auto stop/restart feature cannot be used because it requires frequent stopping and starting of engine which is not possible. I’ve had many Honda dealers and Honda mechanics looking at the issue and none have been able to determine the problem.

Pilot has auto start/stop problems. When it stops, if the exact pedal procedure isn't followed the car will lurch forward and stall engine. After that is it difficult to restart. This situation creates a dangerous situation as the vehicle fails to pull out in traffic under power. Very poor design by Honda and should be permanently disabled for driver/occupant safety.

I have to drive with my idle off because when I drive with it on, there were 4 instances where my car idled & it idled so much that the whole car just turned completely off when I was waiting at an intersection or at a red light or getting off an exit & there were numerous cars behind me waiting. I would have to keep pressing different buttons or drive to park then try to turn the car back on & it would take awhile to turn back on. So to avoid this, I would just drive with my idle off. I did bring it up the the service department at the dealership but they said they didn’t see anything wrong, because it doesn’t happen all the time or maybe because they were just driving around one block, I don’t know. But it happened with me and when my husband drove my car. It’s very dangerous. I finance my car with the dealership and it happened ever since I bought the car. But I bought it as is, so they said they can’t do anything about it.

Auto idle restart and transmission is unexpectedly put in park upon restart. On occasion then car goes into limp mode and powers off.

Our stop/start feature consistently causes the car to stall instead of restarting the engine. This leaves us stranded in or at intersections while waiting for the car to respond to pressing the park and restart buttons. This regularly takes enough time we have narrowly avoided being hit multiple times from suddenly not being able to move. Because it can turn off at any time you are fully stoped we have been caught after having to make a complete stop in the middle of an intersection and then still being stalled when the light changed. Honda has experienced the problem and has only been willing to change the battery. A fully charged and new battery does temporarily reduce the number of occurrences. This has only been inspected by Honda because we have not had an actual accident yet. There are no other warning lights on the car at any point. This is a regular and known issue that they have failed to fix.

When I was paring my phone to bluetooth I noticed my car started to pop up alerts in accessory mode (low power state engine off) that my Honda was hiding critical safety alerts with the brake system and charging system problem and a anti-lock brake system problem when fully powering the car most of theses alerts are fully hidden from driver view the only thing I was able to see consistently was the u3006 control module input power fault with my scan tool this is very concerning that a driver would have to do all of this work to find essential hidden driver major safety alerts.

Engine needs to be replaced vehicle only has 123,000 miles. Diagnostic states sounds like rod bearing has come apart in cylinder 2 Honda recall #23v-751 involves certain 2016 and 2018-2019 Pilot vehicles. This recall is due to a manufacturing error that may cause the connecting rod bearing in the engine to wear and seize, potentially damaging the engine. But yet Honda states my vehicle is not eligible for said recall.

The contact owns a 2016 Honda Pilot. The contact stated that the stability control, head start, tsa, and other warning lights were illuminated. The contact took the vehicle to the dealer who diagnosed that the fuel injectors had failed. The fuel injectors were replaced. Approximately one month after having the vehicle repaired, while driving approximately 60-65 mph, there was a rumbling noise coming from underneath the vehicle and the vehicle started shaking abnormally. Several unknown warning lights were illuminated. The contact decelerated the vehicle, turned on the hazards, and continued to drive home at speeds of approximately 40 mph. The vehicle was taken to the dealer who diagnosed that the engine failed due to a driveshaft failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact learned of NHTSA campaign number: 23v751000 (engine and engine cooling) and was linked to the failure. The manufacturer was informed of the failure. The manufacturer confirmed that the VIN was not included in NHTSA campaign number: 23v751000 (engine and engine cooling). The manufacturer opened a case. The manufacturer referred the contact to the NHTSA hotline to report the failure. The failure mileage was approximately 85,000.

The engine shuts off while driving and attempting to accelerate, happens frequently.

What component or system failed or malfunctioned, and is it available for inspection upon request? "keyless start system" message has been haunting me for close to a year now. Yes, available for inspection and has been by a local Honda service center. How was your safety or the safety of others put at risk? I was left stranded when my vehicle would not start. Battery jumped and I was able to get on but the issue is not my battery, it is the start/stop electrical malfunction that so many others have cited experiencing. Has the problem been reproduced or confirmed by a dealer or independent service center? yes and I've scheduled an appt. With local service center (again). Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? yes, keyless start system problem which originated in 2023. The warnings fluctuated for a while intially but have been on since my car would not start as reported above. This incident took place a few weeks ago.

This vehicle was recently recalled for the start / stop in 2023 after complaining about it since 2017. The vehicle was repaired which resulted in starter and all related components associated with the recall. I questioned the repair as if you can't duplicate the failure (turn it on and turn it off) how do you know you have it fixed. They assured me they replaced all the associated components. Guess what the same problem is happening again. Start/stop system is not working properly again post recall and software update. The us government should go after Honda on this as it is truly a safety issue when your car dies at a stop and go light and then you have cares approaching you from behind at 55mph.

Car keeps hesitating to accelerate, stalled a few times & is burning through gas extremely quickly. Error code "engine emissions problem" came up, believe this is part of the recall.

In 2021, while driving on a highway all vehicle warning lights came on. Engine ran at high rpm and low speed. Honda said is was a software update. Charged for update. This seemed to resolve issues. Car is regularly maintained and transmission fluid changed 2/1/2024. In 2024, the vehicle warning lights (in multiple & varying groups) began coming on and off at various intervals. The car stalled while at a red light on at least two occasions. When I was not near home I would stop at autozone for computer readings; misfiring of cylinder 2, random multiple misfire detected, system too rich bank 2. Car was at Honda for 2nd software update and lights were off at pickup. Lights started again. The mechanic found the vehicle was sending upwards of 100 codes. Repairs were made (and paid for) at local shop 2 separate times. Car is now at Honda diagnosed with engine failure due to bent rod. Honda will not offer goodwill on vehicle. However, the car has a "soft" recall for fuel injectors which seems to be the likely culprit. Kbb in early '24 was $16k. Honda wants $18 k for repair and nearly $1k for diagnostic fee.

The contact owns a 2016 Honda Pilot. The contact stated that while driving at 70 mph, all the warning lights were illuminated. The contact was able to veer to the side of the highway where the vehicle stalled and restarted. The contact stated that the failure was related to NHTSA campaign number: 23v858000 (fuel system, gasoline). The vehicle was taken to an independent mechanic, who determined the failure was due to the fuel pump. The vehicle was taken to the local dealer, where it was diagnosed that the fuel pump needed to be replaced. The vehicle was not repaired. The dealer informed the contact there was no recall coverage. The manufacturer was not contacted. The failure mileage was approximately 135,000.

The engine fails to restart on its own from a complete stop at a traffic light or road intersection with the auto start/stop function engaged. Vehicle struggles to restart on various occasions. Honda America has an extended warranty to replace the starter.

Rolled into a parking lot and the car suddenly stalled right before I could get into the spot - electriconics were still working and what not. Turned the car off and on and pulled in and then proceeded to charge my portable jumper just in case. Came back a few hours later and drove it home - all sorts of sensors were going off but the car was still fine. Once I got home, I swapped the battery with one that I was charging. At this point there was light flickering and more sensors failing. I went to replace with a new battery and it drove fine for a day or two. On the last day, my girlfriend said it started happening again, and she turned around and came back home where it stalled out again. We are terrified to drive this vehicle and purchased a different one out of fear. Please fix this issue, Honda, as it is pretty rampant from the other reports here.

- the idle engine function does not work. I turn it off in general because if it is on, when I stop the car dies and the dashboard and electric functions, malfunction. They turn on and off and I cannot automatically start the car; it takes several times for the car to restart. - today, I went to a pharmacy and when I tried to restart my car to leave, it would not begin. The dashboard went on and off and it took 1 minute for it to restart properly. - my teenage son is now a driver but I will not let him drive the car because it will stall. We drive to school everyday 45-60 minutes there and back; we are in the car a lot. - when I went to the dealer 1 year ago, they were going to charge me $200 for a diagnostic and then $2000 to fix the problem. I told them if I turn the function off, I have no problem. They suggested I do this. They offered no other solution. - now, however even when the function if off, the engine is now stalling. - a few years ago, it stalled at a light on an incredibly hot day so I attributed it to the heat.

After coming to a stop at a red light, the engine auto stop engaged as normal. About a minute passed, and when I took my foot off the brake and tried to start driving, the engine did not start again. The screen on dashboard the said to switch to park and turn the car off. This car has already received the pgm-fi roughly a month ago, after this happened previously.
