Electrical system, Aug 30, 2026
I am reporting a serious electrical shock/electrocution hazard involving the factory-installed 115V AC power inverter outlet in my 2016 Honda Odyssey. While the vehicle was in motion, my [XXX] son was able, without tools, to pull the AC outlet assembly completely out of the interior panel. He was then able to detach the molded electrical connector/plug from the back of the outlet, exposing the electrical terminals/conductors. The inverter/outlet was powered at the time, meaning my [XXX] had direct physical access to energized electrical components. He was about to touch the exposed terminals when his sibling saw what he was doing and stopped him. This prevented potential electrical contact and injury. I immediately stopped the vehicle, turned off the power, moved my child away from the area, and removed the applicable fuse to ensure the circuit was de-energized before securing/reassembling the connector and outlet. No injury occurred, but this was a serious near-miss. A [XXX] passenger was able to remove a factory AC electrical outlet and expose energized electrical terminals without tools or adult-level disassembly. The outlet's mounting/retention and connector design did not prevent a young child from accessing energized conductors within the passenger compartment. This creates a potential electrical shock, burn, electrocution, and electrical-short hazard, including the possibility of a child inserting a finger or conductive object into the exposed area. I request that NHTSA investigate the outlet assembly, retention method, connector, and protection from access to energized components in the 2016 Honda Odyssey, and determine whether other vehicles using the same components are affected. This design should not permit a young child to gain tool-free access to energized electrical terminals. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After the vehicle is off, and after the smart key fob is removed from the vehicle, the dashboard will flicker, the alarm sometimes goes off and the headlights turn on draining the battery and leading to me having to jump the car to get it started. This makes the car undependable as it could happen after driving somewhere and leave myself or my wife stranded. I have taken this in to the Honda dealership but they noted that it did not occur when they were servicing the vehicle and they weren't sure what the issue could be. Many times the check engine light, FCW and LDW lights will come on and then reset after the car has been driven.

The contact owns a 2016 Honda Odyssey. The contact stated that the driver's side and passenger's side sliding doors were difficult to open and close. The vehicle was taken to the dealer on several occasions, and the dealer replaced the passenger's side sliding door motors and cables twice however, the failure recurred. The vehicle was taken back to the dealer, where the cause of the failure could not be determined. The dealer applied lubricant to the cables; however, the failure persisted. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.

One day my car just turned on. Lights come on will not turn off. Dashboard lights up with every symbol blinking, relays under the hood turning off turning on non-stop. Took it to the Honda dealer, who said I needed a VSA module. Only catch here is the part will not be available until October 2024. 4 months from now. Was told they put me at the bottom of the list as my car is 7 years old. Newer vehicles get priority. Rich people first poor people last. When it would run car would randomly just turn off while driving. Car unsafe to operate.
Electrical system, Vehicle speed control, Engine, Apr 11, 2024
The spool valve had a complete seal failure leaking oil onto the alternator causing the alternator to fail. As result the entire electrical system failed, shutting off all propulsion of the van. This occurred while the vehicle was in the high speed left lane on [XXX] @ the [XXX] exit. I had to coast the vehicle across two lanes of 75 mph traffic, cars and large tracker trailers. I was passed by several cars and tracker trailer while coasting across the two lanes of traffic as there was no shoulder on the left side of [XXX]. There were no warning lights prior to the event. American Honda Motor Co. issued Service Bulletin [XXX] on [XXX] to Honda Dealers/Service about the potential for the spool valve casket to leak and fail so that Honda could check for this failure and replace the defective spool valve. The service bulletin covers five (5) different Models and for some Models six (6) model years. The part number identified is 15810-R70-A04, Front Rocker Arm Oil Control Valve (Spool Valve). The correction action is to inspect the front rocker arm oil control valve for leaks and, if needed replace it. The possible causes are the gasket on the front rocker arm oil control valve has deteriorated or the gasket groove is out of SPECIFICATION. Service personnel at Jeff Wyler Honda, 949 Burlington Pike Florence KY 41042, admitted to replacing this spool valve on my Honda Odyssey model several times a month. They admitted that the failure of the spool valve seal can leak oil on to the alternator causing the alternator to fail causing a complete loss of the electrical system and propulsion, seen reports of complete engine fires due to the spool valve gasket failure, noted that the the service bulletin was not attached to my vehicle VIN as did Honda of Jackson 1408 U.S. Highway 45 ByPass Jackson TN 38305. Because America Honda Motor Co. failed to attached the service bulletin to my VIN, my vehicle was not inspected properly for this safety defect.

Consumer complaint: Repeated failed batteries (3), alternators (3), Start button (1) and left stranded multiple times due to no start. Problem: Honda Odyssey keyless entry computer board not fully sealed. This allows dendridic growth of corrosion on the board. This causes a short that endlessly sets the vehicle ignition into "Run" position. Eventually this shorts the alternator and drains battery. Solution: Cleaned and seal affected area.

I am not sure what is going on but my key phob no longer will unlock my van or lock it. My car seems to loose power sometimes but more than normal it almost as if it is going to die as I an driving it. This has been ongoing since June 2023.
Electrical system, Engine, Aug 10, 2023
While driving in October 2022, my car suddenly had the check engine light begin flashing. My car immediately began to lose power and would barely accelerate. Multiple other dash lights then started flashing. I called the Honda dealership who told me to drive it there. I barely made it to the dealership (having to drive slowly, not being able to accelerate, and not knowing if the car was suddenly going to die). The Honda dealership diagnosed it as a failure of the piston rings leading to a catastrophic engine failure. These piston rings needed to be replaced, which could only be done with an entire engine rebuild. This cost approximately $5000. I got the car back and then the next day was driving on a major interstate traveling 70mph. All of the sudden the car completely shut down. It was so extremely dangerous. I had to pull over to the side of the road and wait for a tow truck. The town truck took the car back to the Honda dealer, which diagnosed a timing belt failure. The timing belt and water pump had to be replaced, costing an additional $1-2k. Then in August 2023 the alternator has now failed. This caused the car to again suddenly die while driving it.

Control Module system failure escalated to an extent where the vehicle will not turn off after pushing the off button and cause flickering while the vehicle is in motion. Part #38329-TK8-A01 is currently in the shop due to part replacement on critical backorder. The vehicle has and can shut off during transit making it a hazard on the road. The vehicle had to be disconnected from the battery to be able to shut off the vehicle, but the on-road transit shut-off was not reproduced. Honda Dealership has inspected the part, and they're unable to correct or resolve the part without a complete replacement. Issues before the incident: Lights would flicker, a clicking noise would be heard from under the hood, car alarm would go off with nothing attempting or touching the vehicle.

UNKNOWN I was urged by a Honda World representative to give my account. My vehicle has intermittently flashed forward collision warning failure/lane departure warning and the check engine light. The issue has been reported to the dealership and they've acknowledged that it seems to be a well-known issue with this particular make/model/year vehicle, due to a faulty part. In order to issue a recall there need to be reports. So here you go.

The contact owns a 2016 Honda Odyssey. The contact parked the vehicle, turned the engine off, and removed the ignition key from the ignition but failed to switch the shifter from the drive position. While attempting to exit, the vehicle rolled backward down the driveway and crashed into the mailbox. During the incident, the contact attempted to reenter the vehicle to prevent the rollaway and was pushed to the ground and dragged down the driveway causing multiple injuries which included a back injury, leg contusions, ankle injuries, and a lacerated left leg which required medical treatment. The cause of the failure was not yet determined. The manufacturer was notified of the incident. The local dealer was not yet contacted. The contact was also concerned that the ignition key was able to be removed from the ignition switch although the shifter was still in the drive position. The failure mileage was 101,000.

- dashboard warning lights (engine light, LDW, FCW, Emissions, and VSA) come on every couple of weeks; the warning lights stay on for anywhere from a few hours to a few days, then go off again. - car alarm goes off randomly, very frequently. - when the car is turned off and parked, sometimes randomly I would hear rapid clicking from the dash. Sometimes that clicking would be accompanied by all the dashboard lights flickering on and off for about 30 seconds, repeating that sequence for a few minutes. -won’t start at times. Engine won’t turn off when start/stop switch depressed.

While driving my odyssey it began having the air conditioner blink off and on, radio was blinking off and on and multiple lights were lit up on the dash. There were no lights on my dash and no warning prior to this happening. My car then lost all power as if it was in neutral. I was pushing the gas pedal but the car would only rev like it was in neutral. Then the car began revving itself and the RPM's were getting dangerously high all while I was frantically trying to get to the side of the highway through traffic. I was in the left lane in a 70 MPH area. My blinkers were not working. After I finally got to the side of the road and stopped, the car was able to accelerate again. Then the whole thing happened again. When I shut the car off, the car then began clicking and dash lights were flashing all over the place, but the car would not start, Then I was able to finally start it, but I didn't dare to take it onto the highway again. Please help - this is a life-threatening issue and Honda should reimburse this immediately. I have read this same issue on multiple other chat boards.

When driving, the electric systems in the car completely turn off. You lose all dashboard functions, including blinkers, speedometer, radio and information panel. Car starts to slow and gas pedal does not seem to work. Power steering also seems to stop working. Car gradually slows. Hazard lights do continue to work. When you come to a full stop, car starts again and works fine. The problem is extremely dangerous if driving of a freeway or other multi lane, higher speed road. We experienced the problem almost immediately after purchasing the car (used, with 28K miles, from Paragon Honda in NY). We bought the car back to the dealer and they replaced an electrical harness. THe problem did not reoccur again for around 4 months (we only drive around 10K miles per year), when it happened again on a local road. Recently, in April and May the problem occurred two more times, with the last occurrence nearly causing a serious accident as we were driving in the left lane on the LIE at around 60mph. Getting the car to the shoulder with limited brake, steering and acceleration functions, and not having use of the blinker was extremely dangerous. This is a very serious issue. Bringing the car back to the dealer, but given the short duration of the initial fix, I fear there is a fundamental defect in the electric system. Went online to a Honda Odyssey discussion board, and was surprised that there were a number of other similar complaints. If this is a systemic problem, it is a big one.

IN COLDER WEATHER THE BACK LIFT HATCH WILL NOT OPEN OR YOU HAVE TO TRY AND WARM IT UP SOMEHOW. DURING WARM WEATHER IT WILL OPEN RIGHT AWAY BUT WHEN IT COLD YOU HAVE TO STAND THERE WITH YOUR HAND ON THE BUTTON FOR 5 MINS OR IT MAY NOT OPEN UP AT ALL. PRIOR YEAR MODELS HAD THIS SAME PROBLEM AND THERE IS A RECALL BUT NOT THIS YEAR. I TOOK IT IN AT THE START OF SPRING AND BEFORE MY EXTENDED WARRANTY WENT OUT AND TOLD THEM THE PROBLEM, THEY SAID THEY FIXED IT BUT REPLACED A LATCH. IT WORKED FINE BECAUSE IT WAS WARM WEATHER AND SUMMER CAME BUT THE FIRST COLD NIGHT IN SEPTEMBER IT WOULDN'T WORK. I WENT BACK IN AND BECAUSE IT HAD BEEN MONTHS AND SO MANY MILES THEY WOULDN'T FIX IT WHICH IS CRAZY CONSIDERING PREVIOUS MODELS HAD A RECALL AND THEY SHOULD HAVE REPLACED THAT PART AND NOT SOMETHING IT WASN'T.

I NOTICED A CLICKING SOUND LIKE THE STARTER WAS ENGAGING SEVERAL TIMES AND ALL THE CABIN LIGHTS WERE ON, ALL ON ITS OWN. I HAVE NOTICED THE CABIN LIGHT WAS ON BEFORE WHEN I FIRST CAME TO THE CAR AND I SIMPLY THOUGHT THAT KIDS OPENED THE DOOR BEFORE ME. NOW I AM SUSPICIOUS THAT THE CAR IS RUNNING THE STARTER AND TURNING ON THE CABIN LIGHT IS DRAINING THE BATTERY. THIS ISSUE MIGHT OCCURRED EARLIER AS I HAD TO CHANGE THE BATTERY AFTER ABOUT 2 YRS.

ONE DAY AFTER CHANGING ENGINE OIL AT HONDA DEALERSHOP LAST WEEK MONDAY, THERE WAS FLICKERING ON DASH BOARD AFTER TURNING THE POWER OFF. THE SYMPTOM WAS GETTING WORSE AND ON SUNDAY AND MONDAY (YESTERDAY), THE CAR HORN HONKING ITSELF. AND YESTERDAY, THE DASH BOARD POWER COULDN'T BE TURNED OFF WHEN I TURNED THE POWER SWITCH OFF (ENGINE OFF LUCKILY) AND THE FLICKERING GOT WORSE LAST NIGHT. SO, I DID UNPLUG THE BATTERY WITH A WORRY OF FULLY DRAINED BATTERY OVERNIGHT. TODAY MORNING, I PLUG THE BATTERY BACK AND GET THE SAME ISSUE, AND LUCKILY IGNITE THE ENGINE AND WENT TO DEALER SHOP AGAIN. THEY DID DIAGNOSIS AND SAID KEYLESS ACCESS CONTROL UNIT NEEDS TO BE REPLACED. HERE IS THE SUMMARY OF THE SYMPTOMS: LAST WEEK FLICKERING DASH BOARD WITH FCW SYSTEM FAILED. AND HONKING ITSELF WITH KEEPING FLICKERING. YESTERDAY, I SAW ERROR MESSAGE OF "KEYLESS SYSTEM ERROR". AND I WENT TO DEALERSHOP IN THIS MORNING. HERE IS MY SPECULATION: DURING OIL CHANGE, THERE WAS OIL SPILLING, WHICH CAUSES SHORTING OF CIRCUITRY (OR TECHNICIAN ACCIDENTLY HIT SOME PARTS INSIDE). IT CAUSES FREQUENT ON/OFF OF ELECTRONIC SYSTEM, ENDING UP BREAKING THE KEYLESS ACCESS CONTROL UNIT. THE DEALER DIDN'T SAY ANYTHING, BUT CHARGED ME TO REPLACE THE PARTS SINCE MY CAR IS OUT OF WARRANTY.
