The contact owns a 2014 Honda Odyssey. The contact stated that the vehicle decelerated while driving and the engine warning indicator illuminated, which meant that the fcw and ldw systems failed. The vehicle was taken to an independent mechanic and who diagnosed that the spark plug needed to be replaced and the cylinder was leaking oil, which caused the spark plug failure. The vehicle was repaired, but the failure recurred on three different occasions. The vehicle was not taken to a dealer. The contact stated that the mechanic called the dealer and was informed that the 2013 models were experiencing the same failure. The manufacturer was made aware of the failures and informed the contact that there was no recall and that the vehicle was out of warranty. No further assistance was provided. The failure mileage was approximately 216,000.

2014 Honda Odyssey which is experience the same issue as the 2013 Honda Odyssey where piston ring 1 -4 with leak oil and foul the spark plugs. When this occurs the engine misfires and vibrates significantly and reduces drivability. Due to the warranty extension on prior years this appears to be a known design defect for this model and engine but not for this model year. When the issue has manifested it has been when driving both times has been on a city street. Estimates for repair are $4,200.

P0303 misfire burning oil causing oil loss and misfire on cylinder 1-3

- Blaine, MN, USA

Driving on the highway, check engine light started flashing and car begin misfiring. Had to drive very slow because of the safety issues related to misfire for a few miles to get the car off the highway. Got car to repair ship and they replaced all spark plugs because they were in bad shape and one no longer worked. The car ran fine after that. 4 months later while on highway same misfire happened. I took car to Honda dealership and said the O-rings need replaced. They tried to get Honda to pay for repairs because they said it's the same issue that led to a class action lawsuit for 2011-2013 Honda Odyssey. In that case the "piston rings in certain cylinders may rotate and align, leading to engine oil consumption and spark plug fouling." Honda of America said they would not pay to fix my vehicle even though its the same issue.

Check emission message on dashboard with the check engine light on. On checking the codes via obd - it shows P3400 bank 1 valve stuck error code pointing to a faulty oil pressure switch. I check the engine oil level using the dipstick which shows the oil levels are within the limits on the stick. The dashboard message (check engine light + check emissions msg) suddenly appeared while driving on a warm afternoon at 45mph (about 15 minutes into the ride).

ECM is running roughly

- Dacula, GA, USA

The engine light comes up and engine is buring oil. Dealership checked after 500 miles and said it is burning oil. Told me to keep checking oil level and if low top it off till the next light comes up so that they can get diagnostoc code. Does not make sense. This is a new van and purchased new and 2 years back and now has only 31000 miles.

I stopped the vehicle on an inclined street to talk with a neighbor. He asked me to look at something so, I turned the ignition off not thinking the gearshift was still in the drive position. After the engine stopped I started to exit the car when it began to roll. I applied the brakes then restarted the car and shifted into park. This is a safety issue requiring a recall before somebody gets injured or killed.

I was slowing down to perform three-point turn to park in garage. Slowly (<5mph) approaching end of first arc, I pressed the brakes to stop. It was snowing and slippery, and there was a slight skid of vehicle. I pressed harder on brakes to stop, which resulted in revving of the engine and crash of vehicle into wall/garage support. I looked down to confirm my foot was only contacting the brake pedal. I placed the vehicle in park to comprehend what had just occurred. I placed the vehicle in reverse to complete 2nd arc of three-point turn, and completed parking in the garage.

I was in traffic and driving a steady 50 mph when the engine suddenly shutdown. After I realized what the situation was I placed the transmission into neutral, steered the car off the road as soon as it was safe to do and stopped. I just had the engine oil and filter replaced when this event happened 3.7 miles from the repair shop. I suspected a problem with the oil change. After stopping I checked for oil under engine (none) and then checked the dipstick (full). I had the van towed to the shop where their personnel checked under the engine for an oil leak and then checked the dipstick as I had done. They told me to take the van to Honda. It"S been a week and Honda said I need new heads for the engine because the timing ?jumped?. the oil change had no effect on this failure. So far, nobody at Honda can tell me what actually caused the timing to ?jump". the total repair is being done by Honda and is covered by the Honda's new car warranty. I've never had any kind of problems with this van prior to this unexpected and sudden failure.

This is the second incident I have had where the engine began racing as I was applying the brake. As I was slowing to park the car at work when I felt the car surge as I was applying the brake. I pushed hard on the brake and found the car racing at 2000 RPM. I was able to fumble for my cell phone and get a short video of the racing engine. As I was filming I moved my foot slightly on the brake and car came out of the racing condition and settled to a normal idle. I took the vehicle into the dealer the next day and again they said they could not find any issues. They implied that they wanted their regional person to evaluate the car but I have not been contacted since taking the vehicle in.

As I was coming to a stop light I took my foot off the accelerator and began applying the brake. As I was applying the brake the car felt like it was surging so I pressed harder on the brake. At this point the engine was racing at full speed erratically. I put the car in park and shut off the engine. I restarted the car and everything was normal. I took the car in the next day to the dealer. While I was there another customer overheard me talking to the dealer and he stated his mother's 2013 Honda Odyssey had a similar experience where the engine started racing while stopping. The dealer could not find any issues with the car and performed all dtcs checks. I told the dealer that on two or three previous occasions I felt the car surge while braking but in these instances the engine did not stay racing. This incident was very upsetting as the car could have taken off on its own if I took my foot off the brake.

I went to dinner with my husband on a Friday night, and when we returned to our van, the doors unlocked we got into the van and the keyless start would not work. We tried for 3-5 minutes, no luck, this happened a few months ago, we again did everything to ensure it was not user error (in which the dealership blamed when they said nothing was wrong with the van the previous time). Brake was pressed, key was out, gear in park.... I had to get in and out of the van a few times before the keyless start finally allowed us to start the van... I took it to the dealership repair shop again, and was insistent they fix the keyless start, but they were sooo rude and inappropriate, there was no "error code" and therefore "Honda would not allow them just to replace parts", and the Honda customer service was just as rude!!!! I am no longer a fan of Honda... this is my first and last Honda!

Bought van and only had it a few months before the keyless start, would not start. Attempted for a whole minute, then finally the keyless start worked. I took it to the shop and they could not find any problems with it, basically they told me perhaps it was user error, but I am not an idiot, I made sure the brake was pressed, the gear was in park correctly, and the key was out and close enough for the car to recognize the key was in the car, however, the car doors unlocked fine with the key. Then a few weeks later, while driving there was a "no key" light on, however the key was in the car, and then a few weeks after that the dash board and radio screens were black for approx. 2 hrs, I took it to the dealership repair shop again only to be told there wasn't anything they could find wrong with my van... unfortunately I bought the van used with only 3000miles, and I think now I know why the original owner traded it in with such low mileage.... it is a lemon!

While driving in the bar harbor, me area, our Odyssey was bucking violently at lower speeds/gears. It happened several times and each time it was when we were speeding up from a stop at a light/signal. It happened in lower gears (1st and 2nd) all on the same date. I called a dealer in the local area and was going to take it in the next day but could not replicate the problem. I brought up the issue with our dealer in Virginia and they stated that they hadn't heard of any such issues. Well, after finding this forum, I am glad to know I didn't imagine all of this!
