Major concern, Turbo damage and start stop feature.

I have a major concern regarding needing to idle the engine after driving above 62mph for an extended period of time (per Owners manual- this is required to not damage the turbos). If you have the start stop enabled (default), and you are driving on the freeway for an extended period of time (over 62mph) then exit on an off ramp and stop at the first stop light. Will the car start stop feature turn OFF the engine? If so, doesn’t that damage the turbos per the owners manual (attached).

Having to remember to disable the start stop feature at the exit ramp would be a pain. Would have thought Toyota was able to cycle oil through the turbos as part of the engine shutdown process to avoid turbo damage. Expecting owners to do it with todays Tech is crazy.
Thoughts???

 

This is probably more for liability reduction than anything else, I’ve had boosted cars my whole life and the newer ones (2013+) have aux pumps to run fluids after shut down to pull heat, and that only really kicks in when temps hit a threshold for me.

 

You joined the forum to bitch about that?

Just disable the start stop feature every time you start it.
My wife does that in her Caddy..


Welcome to the forum..

 

I used a turbo timer on my 91 MR2 and woukd keep it running for a minute and a half, but thats all my experience...
Welcome from the A.V.

 

Turbos that don’t run coolant through them get hot as the seventh layer of hell and The old conventional Dino oil doesn’t like that kind of heat so much. So lack of auxiliary cooling would turn the Dino juice into sludge when over heated and then cook the oil inside the bearings When it stopped flowing. So you could harm a turbo if you didn’t let them spoil down and cool off a bit. Modern cars run coolant through the turbos so they don’t heat up like they used to, and synthetic oil doesn’t turn to sludge like the old Dino juice anyway. So in short, For regular daily driver duty Don’t stress about it.

 

F1shittys have the same issue, but it’s not really an issue. Don’t worry about it. Unless your driving the truck really hard, the turbos don’t get as hot as old ones use to. As mentioned above.

 

Plus the V35A-FTS in the Tundra has the exhaust manifolds integrated into the cylinder heads with a dedicated water jacket for the exhaust. These turbski’s are getting more carefully controlled exhaust gas temps fed to them, and that should help immensely in keeping them alive.

 

I know it isn't a Toyota. But you would think I would have had a problem with the f150. I bought a new f150 with the 3.5 twin turbos. Didn't have a clue about the break-in. Idle time needs etc. they drove the truck to me 200 miles one way. The driver was not a ford mechanic. I assure you. There is no way he followed any break-in recommendations. I sold that truck with 90k on it. Never had one issue with the turbos. Oil pan leak. Starter issue That's it. I just want to go back to a Toyota.

 

I believe the brake pedal also has a pressure sensitive switch to over ride the auto stop/start. Press and hold the brake with normal pressure to use stop/start or press it extra hard to over ride and keep the engine running (or vice versa).

There's also the standard shortcut button to deactivate the auto stop/start below and left of the sterring wheel.

 

The Highlander I had as a loaner when the did the fuel pump recall worked exactly opposite of this. Light brake pressure would keep it running, but a firm press would shut it down. I say "light' because what would be considered normal braking was enough to engage the start/stop system. I had to brake lightly at a stop to keep the engine running.

 

That is a great feature (override with the brake) The ford didnt have it... Had to push the button every time you started the car to disable.

 

This mirrors my experience on both Toyota and VW.

 

I've had a 2022 Tundra Platinum for about a week now and here's my experience with the auto stop/start. I haven't had engine shut off on me when I stop normally and also using brake hold occasionally. Only about the last inch before bottoming out will shut the engine off, but the tundra stops well before you get that far. Even if it stops, just back the pedal off a little and the engine will start again. I keep getting this annoying message because it's not activating, see picture.

 

^^^Follow THIS advice^^^....Next question?

 

14mpg and 430 miles of range… those numbers seem familiar.

 

100% there is. My engine in my 22 rarely shuts off on the start/stop feature because of the brake pedal pressure sensor. You have to really mash the brake pedal for the truck to turn off and the brake pedal doesn't require that much pressure to hold the truck stopped at a stoplight.

 

1st world problems, sure, but it IS an unnecessary PITA that negatively impacts the user experience. What would it cost Toyota to make that a user selectable feature in the sytem settings menu (permanently on/off)? Not much on a per unit basis. Add the feature and $50 to the sticker. Toyota will have happy customers and an extra $50 per unit which in time will offset development cost quite handsomely. It's one of those win-win situations that makes no sense NOT to do it.

Obviously, I hate start/stop. It's annoying on golf carts (I prefer battery powered golf carts for a myriad of reasons) and it's even worse in cars. I get annoyed just hearing other peoples cars constantly shutting off/restarting at the stoplights (conveniently spaced every 50 yards and timed to stop all traffic at each one no matter which direction you are going).

Hmmm. Proofreading this, possibly I need to have a beer and relax?

 

Haven't been driving it responsibly, it's new and I've been having fun with it on the first tank. Going 80+ on highway and making the turbos kick in driving around town doesn't help. Just filled up this morning, so I'll tried to drive it normally and got 19.4 going 30 miles to work.

 

At 10:30 AM?
Let's do it..

 

Honestly...as "risk adverse" as Toyota is...if this were truly a big deal then I think they would have a bulletin to their dealerships to make a big deal about this at the time of purchase. I think including this in the manual is more a liability CYA required by the legal department more than anything. Just my opinion.

On a side note: With the number of warnings & disclaimers in EVERY new car owner's manual, I'm surprised manufacturers don't require new owners to watch a 15 min "New Owner" video at purchase and then click some box acknowledging you watched it and were made aware of known warnings. haha. I'm sure that day will come.

 

I agree, have a beer, sit back and enjoy life

 

Don't give them any ideas!

 

That's not too surprising.

On the opposite end of the spectrum, when I purchased my 2012 4Runner as a CPO from a Toyota dealership in central Florida, I asked them about suspension mods. I said to the sales guy & service manager, "I'm going to do some suspension work to this soon and go up a size on tires with some KO2s pretty soon. Is that going to impact the remainder of my factory warranty?"

The service manager looked at me, smiled, and said, "No worries, man! We're a very 'mod friendly' dealership here. Do whatever you want." We laughed about it and they all gathered around my 4Runner about 3 months later when I brought it in for regular service with all the suspension mods done. I did have a few warranty claims over the course of my 9-year 110k mile ownership, but never anything suspension related. It's now my wife's daily.

 

Wonder if one can be ordered without the auto stop/start? There is a code to order the raptor or f150 that deletes the option. Actually gives a 50 dollar credit. I think it saves the use of some precious chips for the manufacturer. My understanding is that is the only reason they started allowing it. I'm sure our EPA overlords don't want this to happen though.

 

The EPA fuel economy and emissions ratings are calculated using the start/stop feature. If the auto companies allowed it to be permanently turned off, the ratings would not be valid. That's why they always default to ON.

You also have to consider that auto makers are measured on a global / company wide fuel and emissions targets as well, so these relatively minor savings and annoyances across a lineup of vehicles can add up to significant amounts and have a big effect on the corporate targets.

 

Salesperson at my dealership said they could permanently disable auto stop/start in the service dept. Not sure if true as they were trying to sell me a car
