2017 Honda Pilot electrical problems

ELECTRICAL SYSTEM

Component/system that failed: The audio/infotainment system (radio), rear DVD entertainment system, and backup camera all fail together while driving. The vehicle is available for inspection upon request. Description of the problem: While driving, the radio works normally for approximately 10-30 minutes, then begins developing static that gradually worsens until the audio cuts out completely. At the same time, the rear-seat DVD entertainment system stops functioning, and the backup camera also fails. This appears consistent with a known defect in the MOST (Media Oriented Systems Transport) bus and FAKRA connectors that Honda has already acknowledged and recalled on 2019-2022 Pilot, 2019-2023 Passport, and 2018-2023 Odyssey models (NHTSA Campaign 23V431), but my 2017 Pilot Elite with the same Navigation/rear entertainment head unit is not covered by that recall despite the identical failure pattern. How safety was put at risk: Loss of the backup camera while driving/reversing removes a safety feature I rely on to see behind the vehicle, increasing risk of a collision when backing up, especially around pedestrians or in tight parking situations. This mirrors exactly the safety concern Honda cited in its own recall notice for later model years — that loss of MOST communication causes rearview camera failure.

The back up camera every so often will be blank. Other times the dashboard warning lights will go on effecting the cruise control, lane assistance, and break assistance. According to the Honda dealership it is the back up camera that is causing all of these problems because there are some parts that are defective because of heat and weather. There are thousands of complaints by Honda owners claiming to have the same issue. The solution is a part that costs over $2000 with a high chance of the part needing repair in a few years. Honda knows about this issue for cars 2015-current. There is a current class action lawsuit as well. We just want it fixed without further issues.

Digital speedometer stop working. It won’t display. It has happened before, and it’s happening again. This is dangerous to my driving as I have no idea how fast I’m driving when there is no display of my speed. I read from Honda Pilot community there are many others Honda Pilot owners have this same issue. This should be safety recall as it’s driving safety issue. Thank you for looking into my concerns.

ELECTRICAL SYSTEM

Since purchasing this vehicle new, the Auto Idle Stop (AIS) system on my 2017 Honda Pilot has intermittently failed during the engine restart sequence after the vehicle comes to a complete stop. When the AIS system shuts the engine off and I release the brake to resume driving, the vehicle intermittently fails to restart properly or does not restart at all, preventing the vehicle from moving as expected. In some instances, warning messages, including a collision mitigation message, has appeared on the dashboard before the car restarts. This condition has occurred repeatedly over several years and has happened at intersections, while stopped in traffic, and while stopped on highways. The inability of the vehicle to restart and move creates a safety risk because the vehicle may remain disabled in active traffic when acceleration is needed. The issue was reported to the selling and servicing Honda dealership (Cambridge, Honda in Cambridge MA) multiple times over several years. In August 2025, the vehicle received Honda's prescribed repair under Service Bulletins 23-008 and 23-009, including replacement of the starter assembly, starter relay, and battery. Despite these repairs, the same condition returned less than one year later and has occurred at least seven additional times. The vehicle stalls and sometimes displays the collision mitigation/crash warning message before restarting. In June 2026, the vehicle was inspected again by the dealership. Technicians were unable to reproduce the condition during testing and declined to perform additional repairs. The defect remains unresolved. The vehicle has already received Honda's recommended AIS repair, yet the same stalling and crash mitigation message continues to occur. The intermittent nature of the defect makes it difficult to reproduce during short dealership evaluations, but it continues to occur during normal operation and presents an ongoing safety concern.

My 2017 Honda Pilot Touring has experienced ongoing electrical and battery-related issues for several years and has been in and out of authorized Honda dealerships numerous times. The vehicle has been serviced repeatedly at both Fowler Honda in [XXX], and Pensacola Honda in [XXX]. Due to the inability to diagnose the problem, the issue was escalated by Pensacola Honda to American Honda’s technical line. After extensive diagnostics over two days, the technicians informed me that Honda engineers are aware of an issue but currently do not have a solution, although they are working on one. On XXX, while turning left from [XXX] onto [XXX], I had sufficient time to complete the turn and pressed the accelerator to proceed. However, the accelerator became completely unresponsive and the vehicle would not accelerate. My vehicle was left partially in the intersection while an oncoming vehicle approached. The other driver could have easily struck the driver’s side of my vehicle, creating the risk of a serious or fatal accident. Fortunately, a collision was avoided, but this incident demonstrated a significant safety hazard. In addition to this loss of acceleration, the vehicle has experienced recurring starting problems and electrical malfunctions. Pensacola Honda found that the battery tests normally when removed from the vehicle, but does not function properly when installed. Despite numerous repair attempts and escalation to American Honda, the problem remains unresolved. I believe this defect poses a serious safety risk to myself, my passengers, and others on the road due to the potential for sudden loss of acceleration while driving.

On May 23, 2026 I was driving family and friends around San Francisco, CA in my 2017 Honda Pilot (48K miles). We were driving up multiple steep hills, up to a 20% grade in some places with a full car of 7 people. The car handled it well. However, as we neared my home 25 miles away, the car started shaking and the check engine light started flashing. We searched online and the advice was to pull over immediately to prevent the car from overheating and causing permanent, expensive damage. We eventually made it home, shaken, and didn't touch the car for a couple days to let it rest. I learned that there is a warranty extension "Warranty Extension TSB 20-100" for what seems like this exact problem concerning the fuel injectors. The spark plugs have been replaced in the last year, which eliminates that as a potential issue. The next week, I took the car to Honda San Carlos where it's been maintained most of its life. I informed them of the symptoms and that the car is eligible for this warranty extension. They tested it and found nothing. I told them that testing it in the shop or driving it around a few minutes on flat ground with one person is not going to replicate the driving conditions we encountered but they didn't seem to care and I had to pay $250 anyway. I took this to another dealership and the guy said it sounded exactly like an Warranty Extension TSB 20-100 issue. They tested it and also could not find anything. I called Honda Corporate and they will also do nothing. This is clearly a safety issue as this problem will happen again at some point. I have a family and young children and do not want to be stuck on the freeway as a road hazard to ourselves and other drivers. Honda has clearly identified this as a problem yet they won't authorize the repair. They are waiting for this to happen again before they'll fix it, and who knows if this ticking time bomb will occur in a safe place or a dangerous one.

Engine Idle at Stop light or Start & Stop at Traffic Stop Light doesn't work. It does stop completely; however, it didn't start after releasing the brake. You have to put the vehicle back in the parking gear, put the brake to restart the engine. This has happened three times in the last week.

This is a follow up to my previous complaint. 11729106. I brought my Honda Pilot to my local dealer. They confirmed there is a problem with the keyless start system on my Honda. I ended up paying around $1000 to have it repaired. I have great concern that this could have caused a fatality. I park my car in the garage at home, and the car started by itself. I have pets and children.

ELECTRICAL SYSTEM

The issue appears to involve the vehicle’s electrical control system responsible for power management and system activation while the vehicle is off, possibly including the Smart Power Control Module and related components. It may be arranged for the vehicle to be inspected. The vehicle behaved as though it had been remote started, initiating engine cranking without any user input while turned off. If this occurs while parked in a garage or enclosed space, it could lead to dangerous carbon monoxide buildup and pose a serious risk to occupants. Unintended engine activation also presents a risk to nearby people or property. The unintended engine cranking event occurred once and was directly witnessed while I was seated inside the vehicle observing other electrical oddities. The issue has not been reproducible on demand. However, related symptoms including the alarm activating on its own and unexplained electrical activity while the vehicle is off have occurred multiple times. The vehicle has not yet been inspected for this issue by a dealership, manufacturer, or third party. No police or insurance reports have been filed. I plan to take it to the dealership tomorrow (4/4/2026). There were no warning lights or messages before or during the event. Prior symptoms include intermittent alarm activation, display flashing, clicking fuses, and electrical activity while off, beginning before the engine cranking incident.

I was stopped at a traffic light, and my vehicle would not re-start when the traffic light turned green. It stalled because the Auto Idle Stop/Start (AIS) function did not work as intended. The dashboard cluster lights were all on (or many of them, at least). I had to collect myself, put the car in park, and wait a couple of minutes to try to restart the vehicle, all while I had a line of vehicles behind me honking. This isn't the first instance. It has happened several times before, and I am familiar with what the Honda service reps say when I have taken the vehicle in for repair, so I'll cut through the nonsense they have told me. I recently replaced my battery with a quality name brand battery, so it's not an issue with the battery. I have had the PGM-FI Idle Stop Software Update recall service performed twice, one in response to a March 2023 recall notice, and again from a May 2024 recall notice. There is something seriously and obviously wrong with this AIS feature. I have looked on many forums and this is a frequently recurring problem. This shouldn't happen simply because I (or my family member) forget to hit the AIS-disengage button. There should be a permanent fix for this feature if it frequently fails.

ELECTRICAL SYSTEM

While driving my 2017 Honda Pilot Elite, the vehicle has experienced four separate incidents of sudden and complete loss of power, including while traveling at highway speeds and during rush-hour traffic. The engine shuts off without warning, causing the vehicle to stop in traffic. In multiple incidents, the vehicle would not restart for several minutes. These incidents occurred on U.S. 19 and Interstate 275 in heavy traffic, creating an immediate risk of collision. In one incident, the vehicle died while traveling at highway speeds. In another, it shut off at a red light and blocked traffic during rush hour. The vehicle has been taken to an authorized Honda dealership multiple times. Diagnostic testing initially found no issues. Later visits attributed the problem to the battery, despite the battery being recently replaced and the condition recurring after replacement. The symptoms exactly match Honda Pilot start/stop engine failure recalls affecting nearby model years. However, because my model year is not included, the dealership refused to repair the vehicle in accordance with the recall, even when I offered to pay for the repair. I believe this represents a safety-related defect involving sudden engine shutdown while driving. The vehicle is unreliable and unsafe to operate. Furthermore, given the repeated failure of this vehicle, the dealership’s inability to permanently repair the condition after multiple attempts, and the ongoing safety risk, I am concerned this matter may meet the criteria for a nonconformity under Florida’s Motor Vehicle Warranty Enforcement Act. I am hopeful Honda will resolve this matter cooperatively and without the need for further regulatory or legal action.

Transmission locked up and had to be replaced April 8 of 2025. I was blessed it did not lock up while I was driving, but did as soon as I pulled in my driveway. While driving that evening I had some issue with it not downshifting. When stopped in driveway could not restart the car. Had to have a special tow truck take it to the repair shop. I never got a warning light regarding the transmission needing to be checked. I had issues prior to the lock up, engine revving, gearshifting too late. Obvious transmissions issue. As I never got a warning light no code would show to have it repaired. I took it to the honda dealer for repair. After the replacement with another 9 cyclinder transmission the autoshut off is problematics causing me to stall out when stopping at lights and intersections. I had a previous experience with the 1999 honda odyessy and had 3 transmissions replaced. I am concerned about my safety as I could only replace it with another Honda 9 cylinder transmission.

I am reporting a recurring “Keyless Start System Problem” warning on my 2017 Honda Pilot. This is a known and widespread issue affecting 2016–2017 Honda Pilot models, as acknowledged by Honda in Service Bulletin 20-117, which identifies a defect in the push-button start/stop switch assembly. In my vehicle, the warning appears intermittently, and the engine sometimes fails to start or requires multiple attempts to engage the ignition. This is a serious reliability and safety concern, as the vehicle may not start when needed, potentially leaving drivers stranded or unable to respond in emergencies. Although Honda recognizes the defect in their service bulletin, they have not issued an official recall and refuse to repair or replace the part outside of warranty coverage. Many owners are being forced to pay out-of-pocket for a clearly documented manufacturer fault. I respectfully request that the NHTSA investigate this issue and consider requiring Honda to issue a recall or provide a no-cost remedy for all affected 2016–2017 Honda Pilot vehicles. Additional details: •Model: Honda Pilot •Year: 2017 •Issue: “Keyless Start System Problem” warning, intermittent failure to start

so i have a Honda pilot and have been seeing a light saying that my collision mitigation system is broke so i took it in for a diagnostic which i was charged for which is fine and normal i guess but they told me that the system was broken possibly from just driving through construction zones and this causes phantom braking so i have to get it fixed but they want to charge me for the repairs which from my perspective the customer i shouldn't have to pay for a defect like that that can cause injurie or much worse

Electrical System – Body Control Module The BCM in my 2017 Honda Pilot fails intermittently, causing the alarm to activate randomly, warning lights to flicker, and battery drain. The issue occurs without warning, even while parked or driving, creating distraction and reducing confidence in the vehicle’s safety. Numerous other owners have reported identical issues online and with NHTSA, indicating a systemic defect. Honda should issue a recall to address this problem.

Failure occurred at highway speed. A host is warning light came on and the car lost power. Lights that came on included emissions, traction control, power steering, all wheel drive and towing (I wasn’t towing anything). No lights were on before the incident. The vehicle lost power and could not maintain any speed. I was able to roll into the breakdown lane. The vehicle was brought to a local Honda dealer who preformed the diagnosis and determined the issue to be a failure of the high pressure fuel pump. Seems this has been the source of several recalls including the 2017 pilot but not my vin. It seems like the recall my need to be expanded

After fixing a few of the recalls, the alarm on my 2017 Honda Pilot would start going off at random times. After several attempted fixes - replacing the key fob batteries, replacing the car battery - the issue has persisted and we noticed a clicking noise coming from the dash. Essentially the car would attempt to turn on without anyone near it. There are no warning messages present. Thus far, it has not replicated while driving. We have just taken the issue to the Honda dealer and they have come back with a $1400 charge to replace the Smart Power Control Module. In researching the issue, I've seen a number of owners have this issue with 2016-2018 Pilots and even seen some complaints in your database.
