2010 Honda Accord Crosstour: misfire or rough idle

Filed Jul 3, 2025 · Engine, Transmission · LA

Hope this email finds you well. I am writing to address a serious matter regarding my 2010 Honda Accord Crosstour, which has been facing recurrent misfires due to what appears to be a manufacturer-induced oil consumption defect in the engine design. Over the past 18 months, I have experienced extensive repairs on my Honda, surpassing any issues I have encountered with previous vehicles. Despite my diligent efforts In maintaining the car with regular tune-ups and oil changes , it is disheartening to witness fluids seeping into the engine, causing damage to multiple components. I have invested a significant amount of money into resolving these issues, expenses that should not have arisen with a Honda vehicle, given my positive experiences with the brand in the past. Upon contacting customer service and receiving a case number, I have found the assistance provided to be inadequate in addressing these issues severity of the situation. The recent revelation of a 2014 lawsuit further compounds my concerns, as it appears that Honda seeks to evade accountability for widespread engine malfunctions, leaving loyal customers like myself in a distressing predicament. Despite the substantial financial outlay exceeding $1200, my vehicle remains inoperable due to the unintended consequences of the oil leakage onto pistons, a situation exacerbated by the lack of proactive measures from Honda in rectifying this critical issue. I have meticulously preserved all documentation, including receipts detailing the damages incurred as a result of the oil consumption defect. While I acknowledge the complexities surrounding warranty coverage and ownership transfer, it is evident that the fundamental flaw lies in the initial design of the engine, which has compromised the vehicles performance and safety. Honda’s reluctance to acknowledge and address this inherent defect reflects poorly on their commitment to customer satisfaction and product This what I emailed to Honda.

I purchased this car in June 2021 for my grandson as high school graduation gift and entrance in college. Driving at a speed of 55 the car tremble uncontrollably and cuts off. I was told that oil leak into the catalytic converters. I had to replace catalytic converters, clean piston, constantly changing spark plugs car misfires, had to replace air conditioner and most of the electrical. What is next. Honda settled a lawsuit March 2014 which this car was apart of it. I wish I would’ve know before I purchased this car. That class action lawsuit needs to be reopened.

Oil consumption is more than it should be. I have to add oil between changes and I always get a misfire because my engine is trash

My car jerks from the vcm module on the car usually when going around 40 MPH especially when entering a turn( I drive mostly on a 2 lane highway) which makes me feel unsafe because it happens when it shuts down cylinders and jerks the car hard sometimes and gives a significant loss of torque. I recently purchased a honda accord crosstour 2010 with 72k miles on their 3.5l v6 engine and was not informed about honda being sued for their vcm module that shuts down cylinders. It ruins piston rings, breaks engine mounts, misfiring, burning oil, and last but not least bent piston rods all so you can get 1 more mile per gallon. I would like for honda to do a recall to fix engines that are damaged and to finally give their buyers an option to turn the vcm off which is known to prevent those problems and make the car not jerk.I got 75k miles now and jerking has gotten worse to where I'm trying to find ways to turn it off. Thank you for your time!

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.

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.

Floorboard/vibration shake at 22mph and 72mph. Brake pulsation - dealer turned rotors, replaced rotors, and still have brake pulsation. We have had numerous problems with our honda crosstour - normal acceleration at 22mph gas pedal, brake, floorboards shake. When cruising at 72mph or going down slight decline entire car shakes. Brakes were pulsating at 4896 miles, 10k miles, 18k miles, and still are not correct at 20k miles. What dealer has done so far - jul 2011 - turned rotors, road force balanced tires/wheels - no improvements with vibration at 22 and 72 MPH - dealer wanted to wait for donor parts to replace drive shaft assembly (we waited 4 months) - honda tsb drive shaft assembly 29 oct 2011 - complained about vibration at 22 and 72mph again, and brake pulsation, dealer replace front axles - no improvements - and replaced front rotors. 18 jul 2012 - complained about vibration at 22 and 72 MPH, and brake pulsation again - dealer replaced rotors - dealer balanced tires and wheels again. August/september 2012 - honda regional rep came in - road force balance tires again -swapped out front tires and rims, shutdown vcm, swapped out computer no improvements - vibration/shudder still present at 22mph and 72mph- brakes still pulsating 24 sept 2012 - national honda rep came in checked valve tolerances - cylinder 5 valves tight causing misfires - didn't improve vibration/shudder replaced axles again, replaced torque converter engine vibration is better at 22mph but worse at 72 MPH - cruising and much worse going down declines. Brakes are still not correct. Our car / engine has been shaking severely for a long time and we are worried about our safety - that something may come loose and cause us to lose control of the vehicle getting hurt or hurting someone else. Honda has not been posting these tsb's publicly.
