Fouled Spark Plug
2008 Honda Accord (Page 1 of 2)
This problem may be covered under warranty. Ask your Honda dealer.
CarComplaints.com Notes: The 2008 Honda Accord has several serious defects: poor brakes, excessive oil consumption, & uncomfortable seats.
BRAKES: There was a class action lawsuit against Honda in 2010 for premature & excessive brake wear. See our page on Honda's brake problems for more info.
OIL CONSUMPTION: Honda issued a TSB about this in late 2011, claiming it could be fixed through a software update to the VCM (variable cylinder management). There are class action lawsuits pending. See our page about the Accord oil consumption.
UNCOMFORTABLE SEATS: Owners have consistently reported uncomfortable seats with the entire 8th generation (2008-2012) of Honda Accords. Complaints range from back pain to leg circulation problems due to bad lumbar support, cushioning, & seat angle. Complaints aren't limited to only a certain body type -- the seat comfort problems are from a wide spectrum of owner height & weight. The common theme we hear is "we never noticed this during the test drive." Unfortunately for unwary buyers, the seat pain is noticeable after 15-20 minutes.

Had horrible engine misfire and work spark plugs at 50k miles and then again at 90k miles. Cars should NOT go through plugs that fast. Did research and found it was attributed to the worn seals from the VCM on the V6 engine. Bought a cheap VCM disabling device from AST on Ebay called the "AST Smart ECO VCM Module" and it works like wonders. I have full V6 power all the time now and I rarely, if ever, go into ECO mode. Found out later I could have bought it direct from their website cheaper, but oh well. At least my car is happy now and I feel confident I'm not riding around with crappy, worn plugs from a horrible engine design.
