In july of 2017 my car started showing that there was a instability in the engine. Turns out that honda knew about this possible problem and had a procedure to deal with it without fixing the underlying cause. It seems that they made the pistons incorrectly at the factory and they could leak oil into the spark plugs causing misfiring in the cylinders. I went to honda dealership to have this corrected and they said they needed to replace the spark plugs, clean up the oil and top it off. Then they would do oil consumption tests for a few months to see if the problem was gone. And it was gone for a while. Just long enough for the warranty to expire so when the problem occurred again, I would be left holding the bag to pay the $2700 for the repair that should have been done when I first went in 2017. I called honda to review my case and they denied me twice stating the age of the car negated any assistance from them. My honda case number is 09490208.

Excessive oil consumption with early replacement of spark plugs in 2010 honda accord v6. All spark plugs were replaced around 65k miles due to an "computer issue" according to my local honda dealership. I was informed at the time that the warranty had been extended to cover the computer issue not an oil consumption issue. Was also informed the issue was fixed. The oil is now changed every 3k miles (which differs from recommendations from honda to change the oil according to the maintenance minder varying between 4k and 5k miles) and having to add .5 to a full quart of oil every thousand miles. There have been no oil stains where I park on a regular basis, leading to believe it is not leaking but burning or being consumed. The check engine light has come on multiple times and usually pulls the code that a cylinder is misfiring. The oil light never comes on even when the oil barley reads on the dip stick. This has been an issue for over 2 years.

I took my car into the dealership, honda cars of columbia, for the air bag recall which was repaired. I informed them of excessive oil consumption and of error codes that appeared. They informed me that there was nothing they could do without engine light on. I called honda cars of america and after getting the run around, they told me that my vehicle was not covered under their campaign for excessive oil consumption and under engine misfire if the light came on again to take car to dealership and they would replace spark plugs 1-4 and update software. I have a v6. The car uses 2-4 qts between oil changes. All I'm asking for is to replace all spark plugs and update software. Your help in this matter is greatly appreciated.

When driving on the freeway on my way to work the check engine light came on. After exiting I checked for error codes (as I always carry the p-code reader with me). The code stated that cylinder 3 was misfiring. I double checked all spark plugs to make sure the connections were okay. The engine light continued to come on, with a rough idle, and engine codes started to be more spontaneous as it stated random misfires/multiple cylinder misfires. I took my car to honda and was told that I likely need to replace the ignition coil, so I did that and still experienced the same problem. I then took it to a shop where they also suspected bad ignition coils. They then did a valve adjustment and was positive that would fix the problem. After performing that job, the car continued with the same rough idle but only populated the error code stating cylinder 3 is misfiring. They took out the spark plug and ignition coil on cylinder 3 and discovered a cracked intake valve. I've spoken to at least 10 shops, 2 honda service dealerships, and 2 personal mechanic friends that all state that a broken intake valve at 107k is very unusual and likely a result of poor design. I have read about the class action lawsuit for all v6 honda accords between 2008-2012. Unfortunately the 2010 v6 6 mt is one of the few models left out of that law suit. I have already had a shop start on the repairs as I have no choice but to have them done asap. I figure an unlikely event like this is due to poor engine design since I have thoroughly kept up with all scheduled maintenance (spark plugs, timing belt, water pump, oil change, etc..). I feel that honda should be responsible for this 2000$ dollar repair.

In late may 2014 I had the brakes (pads/rotors) replaced on my 2010 honda accord, 2 months later in august, I had brake problems again, - rotors were warped again, managed to get them covered under warranty, - 2 months later 10/31 more brake issues so took them to the dealer (so no after market parts), rotors warped, recommended replacement of rotors and pads, - done, 2 months later in december 2014 back to the dealer (now I've pad for them 2x in 6 months)- replaced the front rotors because they were warped, now, 2 months later in february - back to the dealer again for the 3rd time (1s 2 were not a dealer). This time they were warped, but not as bad - so they machined the rotors because this time I went early, when I first stated noticing it. No one figures out why... So, in total, my brakes have been worked on 5 times in 8 months. The dealer said they had a honda corporate rep take the car for a ride, they were advised there was not a brake problem. But that ride was not till after they machined the rotors, of course there would be no problem - this totally has no logic to even have that done! How many times do I have to have them replaced - under warranty or not, and how much time and money do I have to waste, and before someone tries to figure out why the car is going thru brakes- maybe getting in an accident? In addition to these ongoing brake issue, I've already had to have the 3 pistons rebuilt (under a recall , but I had to fight with the misfire problem for 4 months before they would do anything) and the steering rack replaced (thank god I had 100 miles left on my extended warranty).

While attempting to pass a semi-truck on a two lane highway, my 2010 honda accord v6 lost power a few minutes after acceleration. The truck driver probably felt that I was being rude and slamming on my breaks, but I was trying to move to the shoulder of the road because my car was losing power. The car was towed to an independent shop that specializes in honda makes/models. Upon review of the vehicle, the shop found oil in all three catalytic converters. My 2010 honda accord is part of the class action lawsuit for misfire and oil consumption (leakage). I called honda america and notified the company about the issue while attempting to pass. I have been told by the dealer's service department and the independent shop that they have never seen this type of issue. I asked if it was related to the issues identified in the class action lawsuit, both stated they couldn't understand "why oil would be in the converters". I have used the dealerships service department for all work minus the alternator (2 weeks ago). A new shortblock was installed 20k miles ago (part of the misfire/oil issue). My main concern is the situation of losing power in the middle of acceleration. I was extremely lucky today (and I did not have a solid yellow line when I was passing - pretty much a straight away). I told honda america they needed to look into the possibility that the issues with the 2010 honda accord v6 goes beyond misfire and oil consumption. I attempted to google accidents and issues with 2010 honda accords. This is a major safety concern and the federal safety agency should look into this issue (potential causes for accidents involving 2010 honda accord v6 models).
