The bolt that secures the Serpentine Belt tensioner broke off at the engine block. This disables the power steering and the alternator. This is the third time this has happened. Fortunately for me it has happened when I could stop the car without wrecking it. Without power steering it is all most impossible to steer. I have learned that this is a problem with several Honda models. The tensioner is hydraulic and is secured with one bolt. Honda has issued service bulletins about the problem, but they still break. If mine had gone out at road speed or in traffic I may have been seriously hurt or killed. Some other Honda models come with a spring tensioner, and apparently work OK. I have found a lot of information about this problem on Honda forums. Arlington Car Care, in Upper Arlington, Ohio has been great to me in researching the problem and fixing mine 3 times at their expense. …
Component/System: Engine - piston ring failure; oil control issue related to VCM system. Available for inspection: Yes. My 2009 Honda Accord EX-L V6 (J35Z2 engine with VCM) has developed repeated misfires due to oil entering the combustion chamber, consistent with Honda TSB 13-078. It began around 96,000 miles with cylinder #3 fouling. At 121,000 miles, cylinder #2 also misfired. A Honda dealer confirmed the issue as piston ring failure, and oil loss was measured at ~1.5 quarts per 1,000 miles. The issue causes sudden power loss, rough running, and hesitation, especially during highway driving or acceleration. This creates a serious risk of rear-end collisions or inability to safely merge. The misfire occurs without warning; no warning lamps were active beforehand. Brandfon Honda confirmed the diagnosis in May 2025. …
1st the check engine light continues to come on, when it does it makes loud noise and seems to either speed up like idling to fast or loss of power, continues the normal maintained, already replaced the head gaskets and belts it burns through so much oil when we do test on car they say catalytic convertor and then it will stop and work and some thing over and over again, I have 157000 on my car the leather in the car it is forming hard spots on seats front and back I don't have other passengers its like the seats are superglued . I have heard Honda is aware of these problems and with this amt of complaints why is not Honda heard accountable, in park city a fire started due to faulty catalytic convertor I don't want that to happen to me
The engine is burning oil, about 2 quarts a month. The oil level consistently runs low when checked and I have to top it off with 1 qt every 2 weeks. There is no leaking under the car so the mechanic said the engine is burning the oil and I would need to replace the whole engine!. The cost of replacing the engine is more than the car is worth. I just bought it a year ago and thought Hondas were more reliable than this. The mechanic said Honda had some issues with the "rings" and tp check this website for a recall. I do not see a recall but if many other similar cars have the same problem there should be a recall that Honda should fix.
My Honda vehicle's engine grinds or rattles at cold start-up. Honda dealerships or manufacturer (Honda) are not cooperating and not able to fix it with the reason that my vehicle is out of warranty. I have complained several times since several years however Honda / Honda dealerships have been under playing and rejecting my complaints. This is clearly a manufacturing defect. Please do something about it.
I took my Honda in regarding a rattling noise coming from the engine while driving. It has become more noticeable in the cold and during acceleration. After taking it to the dealer I was told the engine is burning oil. Keep in mind my 2009 Honda Accord has 42k miles on it and is regularly maintained. I was told there is a large amount of carbon build up and it would require a number of this needing repair. Piston Rings, Actuator, Timing Chain, gaskets, seals and the list goes on. The alternative was bring the car in every 3k miles for oil changes because of this issue and monitor the oil consumption. Baffled by how this is possible with carbon build up and using premium fuel. Now I come home and search the internet and find out Honda has an issue with the 2.4 liter Engines in 2009 Honda accords. Apparently a service bulletin was issued but I was never made aware of this issue. …
