Hi Scotty,
we purchased a new 2024 ford Mustang GT with V8 engine. The car has only 250 miles so far. The new Mustang has a feature remote Rev using the key fob as shown in the following link. I was cruise try to see this feature. When I tried it the engine was so loud for few 2-4 seconds, spark (fire) came out of the engine and smoke. I am so worry that this rev could cause any damage to the engine?

no sparks and fire are not normal.
I think Ford have lost their minds. 🙄

This has to be the most asinine, useless "feature" I've heard of on a car.
I agree and will not do it again, but I want to let you know that in the 2024 Ford Mustang owner manual, there is one complete page just talking about the REMOTE REV feature. Ford provided an instruction on how to use it and stated this new feature allows the owner to remotely command engine speed using the remote control to enjoy the engine sound from outside the vehicle. I hope I did not damage the engine by doing that for one time assuming Ford engineers already considered the engine safety in the programming to avoid any potential damage.
As I said, an asinine "feature". It would not surprise me a bit if there were a clause in the car's paperwork stating that using it voids the warranty.

If the 'remote rev' feature caused fire or sparks to come out of the exhaust tailpipes, then do not use it. The car's still under warranty, so call the dealership. Explain your concerns, tell them you want the car inspected. You might also ask if it's safe to drive! I believe fire coming out the tailpipes or anywhere on a brand new car would be highly unusual.
I just checked the car using BlurDrive code reader and no code there? It run normal. Btw it spits only one small spark not a lot. Do I still need to worry about it?
Even if the BlueDriver didn't report any codes, the car should not be 'sparking'. Does the car spark/smoke when you rev the engine using the gas pedal? (It shouldn't, 250 miles is very few miles..) adding @chucktobias or @mmj to this conversation for other opinions
No I did not use the gas pedal but I used the key fob. The 2024 mustang has a feature in the key fob for revving the engine. It has two clicks, the fist one will Rev the engine up to 2k rpm, second click will Rev the engine up to 5k rpm. This feature was on the new mustang commercial and the manual. Therefore I did not select the rpm or the revving time, the car does that automatically.
I understand the feature and how it works. My question is does this happen anytime the car is revved up. (Perhaps you only noticed the sparking because you were outside the car, checking out the remote rev 'feature')
I do not know I did it only one time while I am standing outside the car just wanted to see how this feature work. I just drive normal and never exceed 55 mph because it is brand new has only approx 300 miles. I am working on breaking in the engine and plan to replace the oil at 500-1000 miles
Ford provided an instruction on how to use it
Pressing the remotes unlock button and the lock button, in that order, activates the Remote Rev feature.
Each additional pressed combination will increase the rev spike from idle to 3000, from idle to 4000, and then from idle to 5000.
Thank you. You are correct. How bad it will be to use this feature on a brand new car has only 320 miles? I never use it again but I am worry if this could cause any damage specially if I am still breaking in the the engine.
Most wear on a engine occurs at start up. On a cold engine, DO NOT rev the engine at startup, period. Once it's achieved it's normal operating temperature, the oil pressure has built up and the oil is properly lubricating the engine then the rev feature would be safe(r) to use. I personally would not use this feature at all. Once you feel comfortable that your engine has been sufficiently broke-in, typically 1000 miles, it's your call.. https://www.consumerreports.org/cars/car-maintenance/do-new-cars-still-require-a-break-in-period-a5401239097/
Now I got code U2404-92 Gateway Module A code. Do you know guys what that mean?
