Nissan Consumer Affairs Oil Cooler Response

khtso

There is very little legal ground here for any case against Nissan. This car is designed for street use. The car performs as such. If there's a heating issue while street driving, Nissan installed the limp mode to protect the engine. If you somehow destroy the engine prematurely during the warranty period during street use, Nissan will replace the engine. If you decide to add an aftermarket product to your car, if that screws up the car, Nissan won't honor the warranty.

The way to proceed here would be to make it a purely PR issue. Raise a fuss. Make a stink. Call up all the car magazines and television shows. If it gets published in all magazines that the 370Z sucks on the track because it goes into limp mode after 1 lap around a track, people will stop buying it and Nissan will have to address the issue.

This is the scary gray area. I totally understand that if I install an aftermarket cooler, and it blows an oil line, loses pressure, and destroys the engine before I notice and shut it down, that's not a warranty repair for Nissan. What I'm afraid of is when I install an oil cooler, and something goes wrong with my VVEL 10K miles later due to a factory defect that has nothing to do with oil temps, and they deny the claim because an oil cooler was attached to the engine.

Like we've said I think nissan will have a hard time denying a factory defect that has nothing to do with the oil, oil temp, or oil cooler just because an oil cooler is installed.
Either way if that does happen just take an hour and remove it before you take it in. I know the computer can be checked to tell if some mods have been done or if the car has been driven hard but I don't think they can prove you had an oil cooler on if you remove everything.

CPU can not be checked on the Z. The tell tale black box is only on the R35 GTR, and not on the Z. As far as the cpu being checked, there is nothing to check, unless you get it tuned to change you fuel and air mixture. But thats not really necessary unless you add larger injectors and a turbo or two.

Now that could be a potential legal claim. It would, however, be an uphill battle. If you install oil cooler and engine fails and they won't honor your warranty, you can then make a claim against them to get them to fix it. You would, however, have to prove that the oil cooler did not cause the problem. Nissan obviously has a billion lawyers and engineers and experts that they would put up there to state that yes, of course it was the oil cooler that caused all your problems. Then again, with a company that size they'll offer a settlement by fixing your car, but have some sort of non-disclosure agreement in place. Either way, unless and until there is some measurable harm to you, there's no point in threatening to sue.

Let's all sign petitions and mail them to Nissan. In addition, get everyone on the messageboard who have had issues both on the track and off, along with any definitive statements (in writing) made my Nissan, and mail them off to every Auto reviewer in the country.

I agree and lets boycott the service departments for maint. I do my own maint. anyway but we shouldn't give them anymore of our money until they learn a little more about customer relations.

I think you are 100% correct here. Some well written letters to the car magazines that tested the oil-cooler equipped cars would probabaly be published, and the magazines would probably go to Nissan for a comment on why they equipped press cars with oil coolers but will not allow them on customers cars.
