Brake HOLD feature
This week I accidentally pressed down on the brake pedal strongly and I see the word HOLD next to the fuel level on the dash, and the car doesn't move. Golf cart braking...
Was this done via some software update or is this a feature I thought I checked for but am losing my mind?




Acura - button to activate/disable. Doesn't persist into the next restart of car.
BMW - button to activate/disable. Does persist until turned off. I've had my X3 start groaning because I forgot it was activated when entering a car wash!
Mercedes - activates when pushing brakes firmly a 2nd time. Disables when you hit the gas pedal. I prefer this method because I would never have it active when entering a car wash (ever)!

I do not want anybody activating my brakes without my permission.
You may be talking about Hill Hold, which is different. I miss it from my earlier Mercedes cars.
But I definitely like their application of the Hold function.
Different strokes.....

The 2024 auto stop is so aggressive that it turns the car off when its still moving. And then there is a huge delay to get going again. Its insane and probably putting a ton of wear on the engine for absolutely ZERO benefit.

The auto stop while moving is when it’s transitioning from gas to electric. Even leaving a parking lot slowly might be all electric mode until you get to a speed threshold!
I can't imagine parent company Honda not following suit since fuel economy is so important and auto journalists typically review based on the default setting!
As I said I much prefer this to the opposite system on MB where the engine stops at 5mph (no exaggeration).




There are different strategies employed by the manufacturers depending on pure ICE, MHEV or PHEV etc. All in the name of meeting emissions and fuel regulations. Auto stop/start can in fact save fuel and reduce emissions. Engineering Explained did a very good video on the subject if interested, and it does provide more favorable MPG numbers with the standardized homologation tests. If the manufacturer uses auto start/stop in the homologation tests to make the numbers, then they are obliged to turn it on by default and the driver is only allowed to explicitly defeat it by pressing a button. There are actually regulations around this. As said, at the end of the day it's about meeting the regulations.
