I was traveling towing a 33 ft camper. Usually tow at about 62 mph. All of a sudden the truck cuts out then turns back on and "bucks". my lights on my dash light up like a color blinking christmas tree. My speedometer goes all the way to 140 mph, my rpms max out, my fuel gauge goes up and down along with the temp gauge. Furthermore all the gauges and warning lights flash or move in no form or fashion. Steering gets stiff along with the brakes because the truck shuts off. I controlled the truck to avoid crashing in between the on and off periods. This happened several times. Thought it was wiring from camper or brake controller. However, over the last few weeks from about mid Sept it has progressively gotten worse. Now I can't go out of the driveway before the truck starts acting up. There is a bad accident waiting to happen. In my past experience with Nissan is they are reluctant to say anything is wrong and to fix things. I have had enough go wrong with my truck from brakes, electrical, and rear end unit. Just last weekend 20 Oct 12 I took the truck on about a 15 mile round trip and it acted up again. Between July and Sept 2012 the truck would start the shut completely off in parked position. It still does that now too. The truck is now parked until I figure what is the problem. I don't have mega bucks to fix it! someone said Nissan has a computer recall but I have not been notified and I contacted a dealer but they have not called back. Its been 3 days now. They said the description I gave them matches the recall"????????"

Don't know if it's been reported, but alot of people are having issues with the Nissan Titans (many years) with the exhaust manifolds cracking. I have a 2004 and both of them have been cracked for almost 4 years now. I contacted Nissan, they suggested to contact Nissan corporate, and pretty much told me I was out of luck. The manifolds are over $850 each, and both of mine are severely cracked, causing engine, emission, and safety/health problems. I have had to replace many O2 sensors, cat's, and mufflers, due to burning up, and have to drive with all my windows down and short trips due to the exhaust filling the cab of the truck. Something needs to be done, as this is not only an issue, but a major flaw in the design of the truck. I have had checked out at a local shop, and their exact words were "there is absolutely no flex in the exhaust, so when the engine shifts from driving and revving, the manifolds are the weakest point and therefore crack". something seriously needs to be done or looked into. Many Nissan Titan forums hundreds of people are complaining about the same issue. Usually only one is cracked, but I have both cracked. If you need a vehicle to inspect, you can look at mine. I even had the exhaust upgraded to bigger exhaust in hopes of relieving some of the pressure, so it doesn't leak all out under the hood, and that has helped some, but this is seriously an issue with the design and usability of these Nissan Titan trucks. And, I don't know about alot of people, but I can't afford to spend over $1600 in just 2 parts, plus all the other required parts, when I can barely afford to pay the bank on the truck.
