Not really. The most efficient way to warm a vehicle up is to drive it. I believe I have also seen it in an owner's manual.reggiebrown40 wrote: ↑Mon Dec 23, 2019 6:55 am... I would think you would need the car to warm up a bit before taking off, unless I'm just missing something.
Warm up a bit as in give it at least 20 seconds for it to exit closed loop. The owner's manual is most likely referring to they way people used to let their cars warm up for 5 - 10 minutes before driving off, which is excessive. However, It's not unreasonable to give the car 30 seconds to a minute to "warm up." Especially in cold weather.EdBwoy wrote: ↑Mon Dec 23, 2019 7:07 amNot really.

To the hesitation that Kami mentioned, I'd also just tell the dealer to keep it until they figure it out. You have given us a good amount of info to start from, but if you can catch it on video, that'd be even better for the service department.
I also believe this could be some sort of program driven by ECU to prevent a cold engine from revving up, but in cases that I came out of my work garage and had to accelerate to the flow of the traffic it had stalled me for couple of times and that was not pretty.reggiebrown40 wrote: ↑Mon Dec 23, 2019 2:56 pmI think when you immediately try to drive without letting the engine exit it's closed loop process, it may be confusing the computer a bit. As long as your engine drops down to normal idle and you drive away and you have no acceleration issues then everything is functioning normally.
Yes talking old school deisel engines, my dad had a 1978 MB 240D and that you would have to let idle to cool down few mintues in driveway before shutting off. But thats crazy for 21 century vehicles! Infiniti needs to step up their games. lol
If you are one of the unlucky ones with a terrible dealer, just take a video walk around of your car on their lot prior to handing them the keys. Make sure to record the dealership building/signage, etc. State the time and date on the video and purpose of the video.
Yep the exhaust note is more aggressive in closed loop. It's definitely more pronounced with a custom exhaust. You can hear it quiet down, as if someone turned the volume down after about 25 - 30 seconds once it warms up.EdBwoy wrote: ↑Tue Dec 24, 2019 4:01 amYou're right about that Reggie. I assumed we were talking about the old habit of waiting for the needle on the coolant gauge to rise before driving off.
Infiniti does in fact instruct you to let it idle for about 30 seconds at startup.
I know I usually take a good part of a minute to drive off after I push the button. That's the time I usually take to buckle down, make adjustments, and generally just listen to my vehicle.
I might make a poor getaway driver, but I am a good custodian of my vehicles.

Talking of old school habits, here's another one to baffle the masses - Infiniti also tells us to let the engine idle for a few minutes before shutting it off.
That's a good idea Ilya, however I don't like to cause unnecessary damage to my car, that's why I try to avoid going there as much as possible. On a black car even single dust can be spotted from a mile away.Ilya wrote: ↑Tue Dec 24, 2019 8:14 amIf you are one of the unlucky ones with a terrible dealer, just take a video walk around of your car on their lot prior to handing them the keys.
