Notes: Radiators are still cracking, leaking coolant and destroying transmissions. Which is a shame when you consider that otherwise, this would be a great small pickup truck.

A transmission line from the cooler runs through the radiator. The line failed allowing fluid from the radiator to enter the transmission. This caused massive vibrations and vehicle stalling when attempting to accelerate onto the freeway or to pass, creating a hazardous situation in traffic.

I purchased the vehicle in 2007 with 40,000 miles on it. It has been shimmying on the highway since I hit 60,000 miles and in spite of having my tires re-aligned and balanced, it still continues to rock back and forth at speeds over 50 miles an hour. I just hit my 100,000 mile mark on the first of October. On October 18th, I was at my son's daycare and the truck started idling strangely. The truck was puttering and exhausting black smoke. It died in the parking lot and I tried numerous times to get it started. It took about 20 minutes of trying but I got it running again, only to have it die on me in traffic. Once again, I got it started and managed to get it home where it completely died. When I was able to get it to the dealership (after a local mechanic looked at it and couldn't get it started) the dealership told me I had an engine idle air control sensor that was recalled by Nissan. I never received the recall notice but was relieved that my bill was covered. Less than a week after the sensor had been replaced, the check engine light came on. I brought it back to the dealership and they told me my catalytic converters had burned out. From what I have been able to research online, the failure of my catalytic converters is directly related to an out of tune engine (too much air or fuel) which was caused by the sensor being defective. Nissan doesn't see it that way and now I'm stuck with a $3500 repair bill on a truck I still owe money on and have owned for less than four years.

My truck suffers from 2 known problems that has been widely reported and are involved in two Nissan tsbs. I have the faulty fuel sending unit and the whining timing belt tensioner. I am not getting any help from Nissan and just get a flat 'your warranty has expired' statement from them. I feel that they should fix these problems or at least offer a very reduced rate for the repair.

2006 Nissan Frontier fuel system. After fueling up my pickup, the check engine light comes on and gas gauge show empty and dte computer goes out. Being a component of the fuel system this can be dangerous. Any malfunction in a gas tank should warrant investigation and resolution.

I own a 2006 Nissan Frontier, it was delivered with only half the keys programmed for the vehicle, a strange rattling of plastic shrouding in the engine compartment and as I found out a fast set of tires later, the front end out of alignment [ too much toe in ]. when I read the manual I found out that my 4WD vehicle was "not intended to be used off of the road", this was not in any of the presales literature and the reason I buy 4WD is so I can use it off road. At 100 miles after warranty I had to take it in because the fuel sending unit had failed, about a $600 repair on a part that should last 200,000 miles. The mechanic told me their dealership is replacing about one of these a week on a couple of models. When I picked it up I got the trouble light on the way home, I scanned it to see what the problem was [code PO448 ]. I took it back. The first canister they ordered showed up broken [ kind of fragile for something mounted on the bottom of a 4WD ]. parts replaced under the emissions warranty were 14953zp50C filter-canister, 14950-ea20A canister assy. E, and 14935-am60B valve assy.-co. The service order says "...inspected/found no flow very rusty....". as the vehicle only has 36,000 miles on it this does not bode well for the future.
