I have a 2007 RTL with 103K miles. It has never overheated, oil changes were always done when the truck says it's time. Only ever towed a small tent trailer, or a small utility trailer to the dump.

I was a little late with my 90k service. Before I could get it in, it started with the blue/white smoke on start, then eventually started running rough. I took it in while I was out of town on business. I get back to a $1600 bill since the timing belt was due and the brake pads were cracked. But within a week, it was still smoking and started running rough again.

I took it in to the dealership to investigate and they replaced 2 burnt valves and found 100% leakage on #4 cylinder. New seals, gaskets, plugs, coolant, oil and another $1800. When I picked it up, they said the technician noticed a small amount of smoke, so it could either be burning a bit, or it could could be residual from the work. After a week, the smoke is getting worse again, so I guess I'm looking at a full rebuild or replacement engine. What really ticks me off is I bought it as a certified used (with only 6k miles in Feb '07) but had a 100K mile warranty. This happened at 103K! But there has to be a flaw that under the right conditions the same valves and cylinders are having issues. I have always sworn by Honda, and absolutely love my Ridgeline, but I'm very disappointed!
