Took a friend for a ride yesterday and after a couple of WOT pulls in 2nd gear I noticed that the yellow wrench light was on. The car did not run any different. It did NOT go into limp mode. Got home, turned car off, went back out about an hour later and no light. Tried a few more pulls and car ran perfect. No wrench light. Car is a 2014 GT 6MT. Car came from Steeda dealer with Boss 302 Manifold, Steeda CAI, and Steeda 93 tune. Also came with the boss side pipes. Only thing I have added is a bobs oil separator and roush axlebacks. I hate to take the car to the dealer for anything. Car has full warranty even with the tune so if I have to bring it in I will. Can't remove tune as the car did not come with the stock Mani or intake.

I have searched for something on this but most people its happened to have the Auto Trans.

 

Not exactly the same as I have a 13 GT M6 and Ford Procal tune
however I also got the wrench one morning and it went away. I took it in and they did a Crank Sensor Tsb. Neve had the problem again 6k miles so far.

 

Can't you pull the code and analyze?

 

Will try but from what have read unless you plug in scanner while wrench is on it won't pull a code. It was not the check engine light. Drove car again today all over. Zero issues. Ran perfect no wrench light.

 

Are you sure it doesnt save the codes that cause issues?
I had a vette that saved them all the way back from new. Yes there were many.
Would be nice to know if its been thrown before.

 

Hooked up the SCT. No error codes were recorded.

 

Wrench light comes on when car is in need of service, such as low oil etc. Check your oil level, make sure its not eating oil. Keep in mind the wrench light and check engine light are two different things. Since the check engine light didnt come on the tuner wasnt able to pick up any codes since wrench lights dont throw codes.

 

Checked the oil and its spot on.

 

I wouldnt worry about then, unless the car begins acting out or the light comes back on. Worse case scenario you take it to a dealer and have it looked at.

 

Yeah. I don't want to get mental about it. Going to forget about it for now. Will investigate further if it happens again. I know from my motorcycle that the canbus can be very sensitive.

 

Two points... the Mustang does not have CAN Bus and Ford will not warranty anything related to those mods (tune, manifold, etc.).

The Mustang has two Controller Area Networks (CAN) - one high speed and one medium speed - but they are not CAN Bus in the sense that is usually referred to for vehicle electronics. CAN Bus is used mostly in European imports.

Ford will only warrant the parts that came on the car from the factory (makes sense... why should they cover something they didn't manufacture?) but will cover most other warranty repairs as long as the aftermarket items didn't cause the problem. So if you go to the dealer with an engine problem and they determine that the tune or manifold caused the problem (e.g. lean mixture or ignition timing) then you would be out of pocket for the repair.

Some aftermarket manufacturers provide their own warranty to cover those situations. For example, Ford Racing Products adds its own engine warranty for the balance of the factory 3/36 warranty when you have their tune install at an authorized FRPP dealer. Steeda doesn't appear to offer that kind of warranty.

 

We stand behind our products 100% ... OP ... if you would like ... you can contact our tuning dept. to discuss what may have happened.

Thank you TJ. Will do if it happens again. The car runs absolutely flawless and the light has not come on again. The tune is perfect. From idle to redline the car runs phenomenal. I have been dealing with Steeda parts since I had my 1991 LX 5.0. I have never had one single problem with any part I have ever used from them and if I am looking for a part and they make it I wont use anything else. Was the main reason for selecting the car from a Steeda dealer.


Thanks again TJ for offering to look into it. Will definitely call if light comes up again.

I have no doubt that Steeda stands behind their product - you have a sterling reputation. What I don't know (and couldn't find on the website) is whether consequential damages are covered (i.e. engine damage should it occur).

 

Yes, that says exactly what I was saying... an aftermarket part does not automatically cause warranty repairs to be denied. But the aftermarket part itself is certainly not covered by Ford under the factory warranty and if the aftermarket part causes a problem with a factory part, that too could be denied warranty coverage.

And yes, technically, the dealer would have to prove (to a non-mechanic judge or jury) that the aftermarket part actually caused the problem but if they say it did then you would be the one forced to take it to court to get coverage - and they have lots of high-paid lawyers.

My point was that your statement "Car has full warranty even with the tune" is not accurate. Unless Steeda would cover engine damage caused by (or alleged to have been caused by) the tune, Ford could deny warranty on certain engine repairs.

 

There are many factors that go into engine damage for example.

A failure from a tune, particularly our tunes is extremely rare. The tunes we send out are the same tunes used in our Steeda serialized vehicles sold through Ford dealers.

Vehicles that are backed by a warranty, hence need to have a tune that is not going to cause us warranty issues.

Should an engine failure occur, we would work with the Ford dealer for proper diagnostics, this would include not only traditional diagnostics but things such as fuel octane testing and other techniques to fully determine the cause of failure.

Should it be determined that indeed the tuning was the cause of the engine failure and not abuse, over revving, improper fuel octane, etc, then we would work with the customer on resolving the failure.

Best Regards,

Well then I have a serious problem. This car was bought brand new with modifications done by dealer. Made sure car was covered for the full warranty period before I bought it. If that is not the case than I should have my lawyer contact them. I did not modify the car after buying it. It was sold new with full warranty.

 

That dealer may be handling any warranty issues internally. They will get reimbursed by Ford for anything that is normal warranty and will absorb any that may arise from the aftermarket tune. That's a pretty safe bet for them since there is seldom any problem with a quality tune like Steeda. The only thing you might have to be cautious about is taking the car in to a different dealer for a warranty issue that could be attributed to the tune. Also, you want to make sure that some other dealer doesn't decide to flash an update to the ECM without knowing you have a tune.

 

Also met the guy who owns this car at a show. Car also has full warranty. I can understand modifying afterward but buying it new directly from dealer there should be no issue. (Hopefully).
