Does anyone know if it's possible to disable the auto engine start/stop feature that turns the engine of when you come to a stop? I try to remember to disable it every time I drive the car by pushing the button on the console, but I would like to turn it off permanently if possible!

 

Search Amazon for "Autostop Eliminator Lexus TX" ~$100

 

Clear cut video explains it clearly.

 

Got it, thanks!

 

Found this:https://www.4dtech.com/tx-24-26-start-stop-eliminator/ I was thinking about getting one myself. I dont get the auto start/stop. Whenever mine stops it will literally start back up seconds later which makes me questions if something is wrong or why have it.

 

Hopefully the next new redesigned vehicles won’t have this “green” feature since the current POTUS has dismantled this silly idea.

 

Just bought one. Thanks all for the help.

 

Couldn't disagree more. I think it all comes down how well the manufacturer implements the start stop system.

The first generation system in my dad's Audi A8 from over 10 years ago was awful. Downright dangerous at times.

On my 2024 Volvo, the difference between being the engine being on vs off is basically imperceptible. That's the standard we should judge against.

It's the same way with pure EV's. Toyota's BZ4X and Dodge's Charger EV (or any Stellantis product in general) are not just terrible EV's, they're terrible cars. I wouldn't judge EV's by the worst example of them.

The time when a vehicle is stopped, you're literally getting 0 miles per gallon. Why wouldn't you want to save some money?

 

The stop/start beats up your engine and the starter itself. Why have a system that works against you?

 

No it doesn't. These parts in modern engines are literally designed for this function.

They are designed to function under these exact conditions for hundreds of thousands (if not millions) of cycles.

 

That's what makes horse races.

 

Do you have any idea what technology and mechanics are involved to get the start system to work? Do you realize that starters have only x number of cycles built into them? I can't even begin to respond to your other comments. You obviously have no knowledge of how cars function (evidenced by the fact you purchased a Volvo).

 

It really depends on the car. Many, especially hybrids, use a coaxial electric starter motor with a wet clutch. These can cycle indefinitely without significant wear. Others use a beefed up, conventional one-way solenoid driven sprag clutch on the starter that engages the ring gear. These (and the ring gear) tend to have a more limited cycle life. Many newer cars also have electric coolant control valves to manage engine temperature and help keep the engine warm when stopped. The valves moderate normal passive coolant circulation through the radiator when stopped at a light. Technology keeps moving ...

 

Just because the manufacture design this feature for our cars doesn't mean that it won't put more wear on components.

Engine Bearings and Lubrication, Starter Motor and Battery Life, Exhaust System, Engine Oil, Engine Temperature in hot weather.

Google is my friend, but this info makes sense.

 

Your priorities and your choice. Guess I'm going to find out on my new 2026 Lexus TX500h. It's a hybrid and the whole point is that the electric system (traction/HVAC, etc.) takes over with the engine OFF when stopped or in slow traffic. With our 2023 RX350, we just shut start/stop mode off when it becomes annoying, largely because HVAC pretty much stops working when the engine quits AND there is a lag in acceleration from stopped when the engine restarts. Not so on the hybrid - it just "GOES" and the HVAC is always active, engine "ON" or not..

These two cars should be "poster children" for relatively heavy cars with stressed turbo-4 engines and start-stop modes. We'll see how they stand up. So far the 2023 RX350 has been trouble free (2WD gas Luxury edition). My 2008 Toyota Sequoia Platinum 5.7L V8 carried me and my family around in total comfort for 17 years with just routine maintenance. Still looked great in and out when I traded it in for the TX 500h. Same with our older 2010 RX350 2WD Lux - still going strong, still looks great. So the two NEWER Lexus vehicles have a LOT to live up to. I will say the the new vehicles are quicker, more agile and way more fuel efficient than their predecessors. And way, WAY more complex.

One precaution we do take is regular oil changes at intervals no longer than 5,000 miles, or at least twice as often as Lexus recommends. I don't know what they were thinking bumping it up to 10,000 miles. That's ridiculous. A 2.4 liter Turbo-4 ICE producing 275 HP and 317 Ft.-lbs. of torque while running an 11:1 compression ratio and 12 lbs. of boost is going to beat the heck out of ANY oil.
