NHTSA complaint #10145043, filed 2005-12, 74,500 miles“2/25/05 I purchased a used Nissan froniter sc '01. One week later the service engine light appeared. A Nissan technician diagnosed the problem as the oxygen sensors not providing feedback due to condensation in the wire harnesses. The tech. Told me that there was a bulletin he found stating that the wire harnesses in that year Frontier were found to be faulty and replaced with updated harnesses, which I would have to buy along with four sensors, to fix my problem. The cost in parts was $965 and labor is estimated at $880. …”
NHTSA complaint #10114244, filed 2005-03, 52,500 miles“I bought the 2001 Frontier brand new with only 10 or 20 miles on it. Since then I've had it in the shop 8 times for the A/C (thats right 8 times). Each time the service people assure me it's fixed this time. The A/C blows hotter than the heater does and thats ridiculous. When I go there the service manager ( pat burke ) treats me like a criminal instead of a customer. As of today the truck was fixed once and for all, according to them, but I've heard that 7 times before. Very concerned and tired!!! Nv.”
