2016 Honda Odyssey: multiple warning lights

Filed Apr 10, 2025 · Engine · WI

Vehicle had a dead misfire on cylinder number one. Initially occurred in May 2024 - all of my dashboard lights went on and car was very shaky - made me nervous because manual said car could overheat or catch fire, so had towed to shop - Girard's Automotive in Franklin, WI. They diagnosed as spark plug needed replacement. Van was at about 98K miles at the time so recommended changing all spark plugs, which I did. Three months later - in August 2025 the same thing occurred - all warning lights on. This time I brought it to my regular mechanic - Import Minded in Greenfield, WI - insisting it was a faulty spark plug replacement. He removed the spark plug and found it to be oil fouled which typically indicates the vehicle was experiencing high levels of oil consumption caused by a known piston ring issue. He changed the spark plugs at the time at recommended checking with Honda as this was a known issue in which they had put out a service bulletin in Oct 2020 and extended warranties for year 2011 to 2013. I went to the Honda dealership. They were familiar with the problem but stated they needed to diagnose the problem and could not do that until the engine lights came on again. So, I could not reliably drive my car any distances for fear all my engine lights would come and the shakiness would come back. This went on until this last month, March 2024 in which the engine lights came on again and I was able to get it back to the dealership where they did diagnose the issue as the piston ring problem. They would not guarantee me any assistance with the repairs but required I have them done there for any chance at getting goodwill assist to pay for the repair- to the tune of $6000. After the work was complete, they let me know they would not be able to help me out - not because they do not acknowledge this to be a known issue, but because I do not spend enough money at Honda dealerships. Safety concern - overheat/fire and shakiness causing difficulty driving.

The engine failed while driving on the highway. All lights flashed on dashboard and loss of power to the vehicle. There were no prior check engine lights on before it activated and started flashing. Piston 3 failure that had to be replaced (pistons 1-3). Engine had been burning oil but no low oil indication had been illuminated nor was car due for an oil change. Spark plugs and ignition coil had been replaced approx. a year prior due to similar but less severe incident of check engine light coming on and misfiring engine. Six months after the pistons were replaced, the oil pressure switches were diagnosed as faulty and needed replacement due to a false low oil pressure reading.

The contact owns a 2016 Honda Odyssey. The contact stated that while driving at various speeds, the vehicle would hesitate upon depression of the accelerator pedal as several warning lights would appear on the instrument panel. The contact had taken the vehicle to an independent mechanic on numerous occasions where the spark plug have been replaced each time. The mechanic informed her that the vehicle's variable cylinders were the cause of the failure which had resulted in the spark plugs wearing out at a rapid pace. The dealer nor the manufacturer had been notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 80,000. The VIN was not available.

- 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.

We purchased this 2016 Odyssey November 7, 2016. On July 16, 2020 I had to take the car into the Honda dealer. The vehicle jerked violently when I drive from a stop position to first, second and third gears. The dealer informed that it was due to defective brakes. I paid them $1,500 for the repair but it continued to happen. They informed that they could not duplicate the problems therefore can't fix it. On April 17, 2021 I have been getting multiple warning lights (fcw, ldw, check engine) which occur with sluggish engine performance. The engine will misfire and not accelerate as it typically does or shudders/jitters trying to accelerate. Diagnostic tool shows P0301 for misfire in cylinder 1 and P0848 for trans fluid pressure switch faulty. The dealer informed that we have defective piston rings which cause spark plugs misfire and foul. This will cost 5K and they will not guaranteed that it will fix it! My engine problems seems to be similar to the class action suit as per case no. 3:12-cv-1377-si. Unfortunately, it would appear that the defective piston rings issue was not resolved. I'm concerned that any replacement will result in the same issue again with continued driving. Honda dealerships are aware of the issue and Honda offers us very minimal assistance on the repair. However, they should be fully liable for selling cars with defective design, especially after the prior case. When this issue occurred, it put my family in an unsafe condition because vehicle suddenly lost power and the engine began to stutter. At this point my vehicle is undrivable and this has contributed to financial burden in an already difficult year due to the pandemic. Honda should own this issue for the 2016 model year through full compensation on repairs.

We have been getting multiple warning lights (fcw, ldw, check engine) which occur with sluggish engine performance. The engine will misfire and not accelerate as it typically does or shudders/jitters trying to accelerate. Diagnostic tool shows p0303 for misfire in cylinder 3. I changed out the spark plug which was very fouled (saved it) and this fixed it for a few weeks and then it returned. Changed out all spark plugs but issues and code are back again after a few weeks.
