It seems that, during very cold weather, some CRVs with the 1.5T engine are experiencing fuel dilution to the point they stop running or trigger a CEL. One owner says the dealership said he had 2liters of fuel in his car’s sump, others say plugs saturated with fuel stopped working and their cars had to be towed.
Honda seems to have no fix for this yet and none of the owners reporting problems seem to have had their car returned to them. One says 17 similar CRVs are similarly afflicted at their dealership alone awaiting a solution from Honda.
It has admittedly been a really cold winter and the vast, vast majority of 1.5T owners will not experience problems to this degree. But a world of damage could be done before the car gets to the point where it surrenders. Just goes to show that, if these forum posts are correct, Honda TGDI technology isn’t perfected quite yet. Or maybe they’re just not suited to North American locations north of the 45th parallel...
There seems to be a theme with Turbo DI engines... and DI engines in general.
I believe that high octane fuel is going to provide that 'cheap insurance' that is mention in this thread. Manufacturers should never have recommended regular fuel for these engines IMO.
Nice report btw ;P
