The same day that I found out my transmission was ruined due to the defective radiator, I was also told that my timing chain needed to be replaced. The symptom of this was a high pitched whining sound when accelerating. It started about 5 months before taking it in to the dealership. This would cost $1300 on top of the the $3000 to replace the radiator and transmission. I was screwed with having to pay the $3000 to fix a defective radiator/transmission, and now I find out that Nissan is being sued, yet again, for a defective timing chain! Here's hoping that Nissan notifies me this time about a class action lawsuit, and that I will be compensated for having to pay for ANOTHER defective part. Nissan has yet to do right by their customers. Let's see what comes of this lawsuit.

I don't actually remember when the timing chain problem happened or at what miles. I was very glad that I had the extended warranty because the problem happened after my manufacturers warranty expired! Wasn't too upset, things happen but after getting this message about the major problems with the Xterra I am very pissed that the dealer....who did the timing repair never mentioned that or that there was a problem with the transmission.....both I had but the final was the transmission which killed my Xterra....why put $7000 into a car that is probably only worth a little more than that! I think when a manufacturer finds a flaw they should be required by law to report it to ALL owners....I took good care of my baby and then to have this happen was the final. We had been loyal Nissan owners....I now drive a VW Jetta! If the class action suit goes to California ADD MY NAME! I had both of the issues.....

Attention Xterra owners!!! I have serviced my car religiously, followed all Nissan recommendation. At about 100,000 miles I started hearing a slight waning noise coming from my engine compartment. I took it into Nissan dealer and they told me it's your timing chain guides and tensioners. They told me there is a retrofit kit to fix this issue and that it's very common. The cost was about $2,300. I was also advised that if I didn't get it fixed soon that the chain could drop and ruin my engine. At this time in my 7 years of ownership of my Xterra I really haven't spent any money on repairs other then preventive maintenance. So I agreed to go forward with the repairs. It was until then that the cross contamination of my coolant and transmission issue was discovered. My mechanic told me he thinks we may have cough is just in time. The oil and coolant hadn't mixed and was still able to separate when the transmission oil was drained from the transmission. On his recommendations I went ahead and did now both repairs.The recently discovered radiator issue and timing belt work.

Had I know then what I know now. I would have told him to fix the radiator and put new transmission fluid in and SELL SELL SELL. In less then 1 year later I'm now faced with the costly repair of rebuilding my transmission due to water getting into the transmission. In the last 15 months or since my car turned 107,000 miles I have dumped $3200 for the timing and radiator repair, $1800 for the check engine light (Catalytic converters and sensors) repair and now a rebuilt transmission of $3000 totaling $8000 dollars in the last year on this car. Where does it stop Nissan?

My car is making a whistling noice when I accelerate. It just started last month and I took my car into a trusted mechanic that specializes in Nissan's in Tucson. He found that I needed two pully's replaced, I paid $300 and had them replaced and now the noise it worse. Upon doing my own research I have found that there is a Nissan bulletin about this problem and MANY others complaining about the same problem. Nissan has issued service bulletin (NTB09-128) regardng this issue. Replacement of both secondary timing chains and the tensioner shoes will be necessary to repair this. This costs approx $2000 and Nissan will not take responsibility for any of the cost.
