Can anyone tell me if an Osiris tune would void my powertrain warranty? I know the ECU can/will show the date of the last adjustment made to it. So flashing it back to stock to get work done at the dealership seems to be detectable. I thought I remembered the owner's manual saying something about modifications to the computer would void the warranty.

I know a lot of you guys have a tune and would appreciate your feedback.

UpRev, any ideas?

 

Good question.. I'm sure many of us would like to know the answer.

I'm pretty sure that there is a "stock" map. Not to sure if Infiniti can detect it and void your warranty.

 

This has been asked a billion times: A modification will not void the warranty unless it's the source of the problem. And obviously don't expect to, for example, get the ECU repaired if the ECU has a malfunction and you just happened to have a reflash. Or, if your engine fails prematurely and you were forced induction. You know, some of the common sense issues.

Also, even though by law, they can't deny you warranty unless that modification caused the problem, don't expect it to be a walk in the park when it comes to getting warranty work on a modified vehicle. Dealers will pull things out of their a$$ to avoid warranty; you just have to make sure you aren't passive about it.

 

Thanks for the insight. You'd think with over 300 posts in 2 months I'd have seen this question asked and/or answered but I haven't. I guess it's time for a self-flame. Burning........................

 

A dealer has only 2 sources of revenue, your wallet and their largest customer Nissan Warranty Corporation. When the dealer asks Nissan to pay and they refuse they tell you it's not covered and you need to pay.

Up to you to persuade Nissan to pay and tell the dealer they agree to pay.
If you purchase a new vehicle from the same dealer a special situation occurs in that for the first 12 months or 12,000 miles the dealer may share in cost during so called adjustment period [based on the profit they made in selling you the car].

 

I understand how that works, there are a few laws that help us in that field. I was just curious if anyone has experienced this type of situation where a dealer denied warranty work because they found the ECU had been played with.

Basically, how easy is it for the dealer to detect that you were running a piggy-back or had a re-flash?

 

The laws only help you if you have the cash to retain a lawyer and pay expert witnesses and the time to wait years for justice to wind its way thru various courts.

Most warranties have an arbitration clause where you both pay someone to decide.

People still don't UNDERSTAND A DEALER CANNOT DENY WARRANTY. A dealer has zero to do with warranty other than they ask Nissan and if Nissan agrees to pay the dealer the dealer does the work.
Nissan may ask dealer what they think, whether owner has followed warranty requirements and has been a good customer. But Nissan is the ultimate decider!

If you are a good profitable customer to the dealership [oil changes, services, sold you the car etc] they may bend the rules a little but they usually won't lie to Nissan.

REMEMBER dealers are independently owned businesses and as such they can flat out refuse to deal with you or your car. Up to Nissan to find a dealer who will if you **** dealer off.
As those who study the current US auto crisis understand only a bankruptcy court can remove a dealer's franchise once given! State laws protect dealers from Nissan and abusive customers.

 

I am having issues right now with Nissan I have an uprev reflash, and Had a check engine light come on or gas cap and something else they saw my timing had been played with and they said have a nice day... The car went in for a window motor to be replaced, and a throw out bearing....

 

average nissan technician is not going to know that the stock ECU is capable of 5 different maps which can be controlled by using two switches on the steering wheel. So no, nissan will not void the warranty unless they call the person who developed the nissan ECU and find out that there is more than 1 map used on the ECU.

 

Thats not true... An Average Nissan tech will not look at the Ecu unless its for a check engine light, or a problem along those lines. They will see timing is changed.... So your right they won't need to called the person who developed the ecu.....

 

Doesn't timing change depending on weather anyway?
