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.

My vehicle problems started on February 6, 2024 while my daughter was driving back to her house. My 2016 Honda Odyssey EXL started shaking violently at 55 - 60 mph. Upon towing my vehicle to have my certified mechanic to check it out, check engine light was on with codes and misfires. He determined that the variable timing valve solenoid was bad. He replaced faulty part as well as both oil pressure switches and it then came up with check engine light, as well as FCW, LDW, & anti-skid warning lights!? It also had a couple different codes. He then replace other variable timing valve solenoid on front of the engine. After taking vehicle to dealership, to get diagnosed, they suggested several repairs totaling over $3800, which none could insure that it would fix problem (2 of their suggestions were already done by my mechanic). Taking dealership suggestions, my mechanic replaced spark plugs and coil boots, adjusted valves which were fairly close, along with new valve cover gaskets. Now my vehicle runs better but has this engine knock when engine switches from ECO mode to regular full cylinders. Asked dealership about checking/reprogramming control module, but they won't do it!" Any suggestions??" Considering purchasing bypass kit even though I will lose gas mileage

May 2, 2022 - While driving home one evening, my check engine light came on, flashing. I was able to get into my neighborhood and once I got on my street, the front of the car started shaking violently. I made it into my driveway. This was very distressing and frightening. Scheduled a tow through USAA mobile app for next morning to be taken to Honda. There is way more detail - can't paste all here. July 9, 2022 - At approx 10AM, we left our vacation rental and started the drive home to MS. My check engine light came on and started flashing again. I made it to the middle of the island and met my husband. I was visibly shaken because I knew this was a serious issue. I had three kids and a 175lb dog in my van, along with half of our belongings. If I had gone a few miles or two more, I would have been stranded on a four-mile bridge. I had driven my car frequently while we were on the island (2 weeks) and there were no issues - until this day. - Again, I have WAY more information on this - cannot paste it all here.

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.

Failure of computer module in my 2016 Odyssey caused the key safety systems to all fault. ABS, traction control, LDW, and other systems all went into fault after a light tap on the breaks at parking lot speeds (less than 10 mph). This van has under 30,000 miles on it and was purchased by me brand new.

I lease a 2016 Honda Odyssey. Upon arriving home, I pulled into my driveway extremely slow. I was putting the brake on. The car was not in motion. When I moved the car from drive to park the car accelerated on its own. It hit the side of my house dislodging fourteen bricks. The airbag was deployed. I have black and blues and the residue from the airbag burned my finger. The vehicle is being evaluated by the Honda dealership I leased it from.

At the time of the accident (06/22/2016), I had only owned this 2016 Honda Odyssey for a month (didn't even have plates on it yet). I dropped off a passenger at the front of the diner and drove slowly East through the parking lot. The lot is narrow, crowded, and busy, which is why I did not have my foot on the accelerator at any time. Instead, my foot was on the brake regulating a very slow, creeping speed. I decided to park in a stall that faced West which meant I needed to make a moderately wide, hard, right U-turn. There are short security poles at the head of these stalls to protect diners inside. The vehicle was about 150 into the turn, about five feet away from the pole when it suddenly surged and accelerated on its own. I was confused because I was very aware that my foot was on the brake pedal. I stepped down on it, but it was too late. The van surged into the rest of the turn and slammed into the parking pole leaving a deep dent in the front bumper. Because I felt unsafe driving it, it was towed to the dealership's service center. The next day, after checking the car's computer, Honda found no fault codes so could offer no reassurances that this would not happen again. I submitted the repair of the bumper to my insurance company so that there is record of this event.
