Pathfinder 6-cyl

  • 110,000 miles


My 2005 Nissan Pathfinder bucks as I accelerate. I took my car to lithia Nissan and they informed me that there was a defect with the transmission and radiator, and that they saw milky fluid in my car which indicated transmission and radiator fluid mixing together. The cost would be $5000 to fix both. The next day I took it to my personal mechanic, and he checked the fluid which was clear. The bucking problem still exists in my car, what else would cause this problem. The dealer said I was out of the warranty stage so I would have to pay for the repair, I don't trust them now because they told me false information regarding the color of the fluid. What should I do ?

My 2005 Nissan/Pathfinder was leased from ray brandt Nissan in July 2005. In April 2009 I purchased the lease. In January 2011 I began to have problems with the vehicle. It was determined that the issues were related to the transmission and radiator. The technician [xxx]at [xxx] referred me to the national consumers dept. Of Nissan because this was an issue they were aware of but, had not notified the consumer. The representative [xxx] ( 800-647-7261 ext 47116) at the national division / Nissan usa., acknowledged the default and therefore they replaced the transmission and radiator. This they considered was a "good will' measure because the vehicle was out of warranty by 200 miles. I drove the vehicle for 5 days and the same issues arose again. I brought the vehicle back to ray brandt.this time they informed me that the issues were related to the catalytic converter. Apparently it had come apart and damaged the engine. The dealership, ray brandt again informed me that this was also a defect by Nissan and referred me back to the national consumers' division, Nissan usa. I contacted [xxx] again. This time she informed me that it was Nissan' policy to extended only 1 good will measure. They refused any assistance. While awaiting for her response and the vehicle still in the shop at ray brandt, a re-call was issued on the engine. [xxx] and Nissan still contend that they only extend 1 "good-will" measure. Both Nissan usa and ray brandt Nissan acknowledge the defaults and faulty parts however, neither are willing to assist. In addition I have considered purchasing another vehicle from ray brandt but they have refused to offer a appraisal value for a trade-in. Prior to these issues I had never experienced any problems with my Pathfinder until Nissan' defective parts malfunctioned.I am appealing to you for your assistance in rectifying these issues.

There is an exhaust system noise when a person sits in the rear seat. The Nissan dealership refuses to replace the faulty exhaust system. The exhaust system has shifted towards the front of the car causing the noise.
