Glow plugs on 2025 Cummins

Well that sucks. I don't want my truck to wait to start with my foot on the brake.

Perhaps use the plug in engine heater ?

One of the most under-utilized option on these trucks.

By. Far.

Honestly I don't think it'll really affect me either way. It doesn't get colder than 30 here really.

I noticed on my 2025 Ram 2500 with Cummins that in cold weather (sub-freezing temps as low as 13 degrees) there is no delay between me pushing the start button and the engine starting - same with remote start. The engine runs rough for about 5 seconds then smooths out. It leads my to think that the glow plugs are not warming up. The dealer says that there should not be any delay in starting and that the glow plugs work immediately. Anyone else have this situation or have you heard that this is normal? Definitely different than the 6.7 with grid heater. Thanks

Mine does the same thing and not always in super cold weather.
