Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I drove somewhere, parked the truck and I smelled something burning and saw smoke coming from under the hood. I asked someone if they had a fire extinguisher and they did. I opened the hood and the guy used the fire extinguisher to put the fire out. It started in the wiring harness under the hood. More specifically, there is a resistor and a capacitor coming out of the wiring harness (near the driver-side headlight / distributor coil area) that was on fire. I don't know how many Nissan trucks have this defect, but that's for Nissan and the government to keep track of. …”
