The contact owns a 2002 Nissan Frontier. While driving approximately 30 mph, the engine warning indicator continuously illuminated until the engine was turned off. On a separate occasion the vehicle jerked violently with a reduction in the engine power. The vehicle was taken to an independent mechanic where the knock sensor, mass air flow sensor and four oxygen sensors were replaced. The failure continued to occur after the repair was performed. The vehicle was taken back to the independent mechanic for the second time and the wiring harness was replaced. The manufacturer was notified of the problem and they informed the contact that the wiring harness connectors exhibited corrosion as a result of not being weatherproof during production. The approximate failure mileage was 70,000. Updated 04/10/12 the consumer stated he spent close to $2000 repairing the vehicle. The check engine light continued to illuminate, after replacing the O2 sensors four times. Also, the wiring harness had to be replaced because when the vehicle was manufactured it was not weather proof which caused corrosion in the wires, which sent incorrect signals to the vehicle's computer. The consumer no longer owns the vehicle. Updated 05/31/12
