This Variable Cylinder Management system in Honda's V6 engines appears to be a colossal engineering failure. This car (2010 Accord Crosstour EX-L) has actually been burning oil from about 19,000 miles on, but within the last 6 months at a prodigious rate - about a quart every 1,000 miles. I've had the the computer adjusted at least 3 times by the dealership with promises that the oil consumption would cease. Now, I am calling Honda directly to vent my frustration and need to remedy this asap.

I have been a loyal Honda driver starting in 1993 with the purchase of an Acura Integra, then an '02 CR-V, then an '03 Accord, and an '06 Odyssey (which has the same VCM system - doesn't burn oil but spent over $1000 replacing every motor mount due to excessive vibration by 90,000 miles). I take care of my cars impeccably and each of these vehicles were driven to well over 150,000 miles (Odyssey - 157,000miles and Crosstour - 89,500miles are currently under my ownership); the 4 cylinder engines ran flawlessly, the V6's are a JOKE! The engineers who think 1 - that's right you heard me - 1 extra mile per gallon justifies a variable cylinder management system vs. an extra gear in the transmission (like overdrive you numbnuts) are complete idiots.

Honda seems more interested in dazzling motorists with high tech innovation when common sense should prevail. I am done with Honda!!!!! (I've already leased a new Toyota Camry for my college bound son and couldn't be happier!) I need reliability and a company willing to take responsibility for their mistakes - this issue took a CLASS ACTION LAWSUIT for them to finally acknowledge this problem. Thank you for letting me vent!!!

I NOTICED THAT BETWEEN OIL CHANGES THE ENGINE LIGHT WOULD COME ON. I WOULD ADD OIL ON A REGULAR BASIC. A FEW MONTHS AGO THE WRENCH LIGHT CAME ON WITH THE ENGINE LIGHT. I ADDED OIL AND HAD THE LIGHT RESET. YESTERDAY MY WIFE CALLED AND SAID THE ENGINE WAS RUNNING REALLY ROUGH. WHEN SHE GOT HOME I ADDED OIL BUT A FEW SECONDS AFTER RUNNING IT BEGAN TO RAISE AND LOWER THE IDLE. IT STAYED HIGH. I PULLED THE CODES ON AN OBD AND IT SAID MISFIRE OF SPARK PLUGS. I CHANGED THE SPARK PLUGS WITH NO CHANGE. MY NEIGHBOR PULLED THE CODES AGAIN AND FOUND P3400, P3497 AND P303. THERE IS A SERVICE BULLETIN THAT SAYS THIS ISSUE IS A COMPUTER ISSUE AND A OIL PRESSURE MONITOR PROBLEM COVERED BY HONDA. THIS ISSUE WAS STATIONARY AND WHILE MOVING AT ALL SPEEDS.

I was driving down the highway and my car starting running really bad and the check engine light came on. It felt like I had a fouled plug. When idling I had to put the car in neutral and give it gas to keep it running. It would eventually get up to speed but it took a while and ran really rough.

I took it to a shop close to home and after several hours of diagnosis they said I was low of oil. Kind of crazy no oil light came on but I was over 2 quarts low. They gave me a Honda Service Bulletin 13-031 which stated if the oil is low, this bulletin does not apply. I had them do a full synthetic oil change and then I immediately drove to my Honda Dealer. The bulletin says that if the car is not low on oil you need to replace the rocker arm oil pressure switch. At this time the car is running fine but the check engine light is still on. The dealer runs the code and says I need to have the rocker arm oil pressure switch replaced.

They also showed me the 13-031 bulletin. I said the car was low on oil so you are not supposed to go by that. He stated it was not low on oil. I let them know first thing that the oil change was done less than an hour before I got there. The dealer said we have to go by what it says at the time I you are here. They were aware of this issue and if I replaced the part I would receive a software update and would no longer have issues. By the way, they also told me like everyone else with the issue that Honda says it is normal to loose a quart of oil every 1000 miles and I should change my oil every 3000 miles. With full synthetic I should get at least 7500 IMO.

My choices were to get the part replaced or get another $80 oil change right then so they could do an oil consumption test. They assured my the rocker arm option would fix my issue. I did what they said and at about 4000 miles I had the same problem. Luckily I knew it just needed oil so I added a quart. When my indicator was at 5% I took it back to Honda for an oil change. I explained the issue again. They started an oil consumption test. At 500 miles no oil loss and at 1000 miles no oil loss. Right now I am at 25% oil life remaining on the indicator. I was advised to get the oil changed at 15% life and that is what I plan to do. So far it is still running ok.

We bought a 2010 Honda Accord Crosstour for our daughter. Six months after buying it. We took it for an oil change and was told the car had no oil. The mechanic told me to keep an eye on this problem. I keep the oil changed on time typically before 3,000 miles. About four more months go by and my daughter calls saying she's aside the road broke down. Her car was smoking and shaking. Her car was shaking. The mechanic that works on our vehicles was close by and ran to check on her. He checked and said it had no oil. He added oil got car to shop. He told us that it was bone dry and pistons were back firing. He said a car with this low mileage shouldn't back fire pistons and that oil doesn't disappear from the vehicle. Knowing this wasn't the first time the car ran out of oil. He looked online to see if this was a problem with Honda cars. He found that this was a problem and there were lawsuits against Honda for the same make and model of my car. He suggested we take it to the Honda dealership so they could help with any recalls. That was such a waste of time. Three trips taking off work school dance running back and fourth 20mins both ways to Bryan Honda Fayetteville. First time was told no problem. They changed oil and told me to come back in 1000 miles. Second time was told to much oil was in that may be problem. Hmm didn't they change the oil? Third time changed spark plugs misfire. Fourth time my favorite, oil consumption test was fine, car was a quart low on oil, added oil..

I was told by dealership and Honda Corp that it was normal for oil to be low. It's normal to add oil in between oil changes😂 Wow good one Honda.

I bought a Honda on quite a few referrals because they were supposed to be solid cars that last. I had actually been having issues with the engine, in one form or another, a couple years after I bought it. I would take it in and it would be fixed (?). Until a few months ago when the engine and traction lights would go on for a few days then off, then back on, then of again. The final time they went on they were blinking and my car was acting very sluggish, it was not getting a lot of power so I took it in to a Honda dealer for a diagnostic. After picking my self up off of the floor from the estimate that they gave me, I took their print out to another repair center, that rhymes with, Hirestone, because they had taken care of a few things in the past and had great customer service and comparable pricing. One week later, my engine and traction light came back on and I flipped out! I took it back to 'Hirestone" and they took it in and a few hours later, here I am reading about the lawsuit with Honda over the excessive oil usage deal.

Now I will be super inconvenienced to find a way to take my car in to a dealer for a couple hours for my 3rd oil change in about 3-4 weeks so they can monitor the usage and determine if I qualify to have the piston rings replaced, a 1-2 day job. Also come to find out that if it is the lawsuit issue, American Honda does not offer a rental car for me while they are fixing "their" faulty issue. I didn't ask for this headache, they knew about it a few years ago. They should pay for everything!!

Urggggggg!!!!
