Over the last 4 years I have been able to trust this car again. It had the typical transmission failure these cars have. Just as I was getting over that and realizing every car has its problems. I have this problem...On the way down to California from salt lake, in Las Vegas i stopped to get gas. Started the car no problem, power steering felt very viscous, figured it was from the warm weather in Vegas. I get on the freeway going 65mph and about a mile out of Vegas the car stops. I pull off to the side and call a very car savvy friend he says sounds like a fuel problem or a timing problem. I check under the hood, a belt has fallen from the engine. Under further inspection its the timing belt, which was replace at 100,000 miles. It isn't broken, just fell off and sawed its way through the camshaft cover. Now I'm waiting for the diagnosis as to whether i was lucky and have just a problem of getting a new timing belt or overhauling the engine if i bent any valves. I had complete faith in this car finally it gained my trust. I feel so betrayed by this I don't know if I can drive it back. When i do, it will be for sale. I'm willing to possibly give Honda another chance by buying an Acura, but i don't know. I'm leaning towards Ford or Mazda now. I don't understand how a belt falls off though. By the way nothing was amiss with the belt everything intact covered. New tensioner along with water pump when belt was replaced. Something in the engine failed and now waiting to find out what. Will update when i get a call tomorrow.

Update from Mar 22, 2011: Got a call from the mechanic. Tensioner pulley bolt broke. Cost is 900 dollars. Better than an engine, but I am done with my baby. Just can't trust her anymore.

The car wouldn't start after being parked at work all day. I couldn't replicate the problem anywhere but there. It happened about twice a week. Finally, we determined that it was on hot or humid days that it was happening, and since it was parked in the middle of a lot, the heat was worse. The mechanic at the dealership said the relay switch on the fuel pumps were known to be affected by the heat. We changed it and it hasn't happened again since. It is a very easy fix since the fuel pump is accessible under a plate in the trunk. The part was only about $100. Better than the $300 to $400 for a new pump.

Update from Nov 10, 2009: Here we are in the middle of November 2009 and the car has not had the problem since we changed the fuel pump relay. I received a couple of e-mails from people asking if the problem was fixed, but for some reason, the system would not allow me to answer them, so I figured this should do it. It seems the problem was definitely that relay and when this problem occurs during extreme temps or temp changes, I would say try this first. It is an easy fix for anyone who knows what they're doing and a relatively cheap one to have a shop do for you. Hope this helps everyone.

Engine of 2000 Honda Accord EX V6 will crank several times but will not start. Tends to occur when temperatures dramatically change, specifically in cold weather. Upon being towed to repair shop, problem could not be diagnosed because it magically started when there. Had main ignition relay replaced and car ran for a couple of weeks. Problem has occurred again, for the 3rd time now. Very unreliable and inconvenient. The following is work that has been done

Always on time for oil change, scheduled maint., etc...

Battery replaced only 4 months ago)

Have had all cables, plugs, and wires, connections inspected

Full transmission replaced at 80,000
