Weak acceleration uphill

I just notice the car actually switched gears, but it would not rev past 2500rpm. It's like it's limited at 2500rpm. Definitely, I will ask to test drive other 4runner to see if this is a thing to 4runner. The reason why I wonder if the car needs to be broken in is because the challenger needed to be broken in 500 miles, to be able to activate super track pack. The toyota recommends not to tow nor rev past 3000rpm for the first 1000 miles for the 4runner to be broken in makes me think if the car is programed like that until it passes the break in period.

 

The possibility is whoever deliver the car from Dallas to Houston was using cruise control for 290 miles so the car probably adapted to it and limit the rpm at 2000rpm. I dont know though. This is what I am guessing, but I'm going to be patient to see if everything back to normal after breaking in the car.

 

Oh, so this is news to us. Unless I have missed reading about it being driven by a dealer jockey.
I would be pissed to hear that it was not delivered on a trailer, because you don’t know how it was driven.
That just sucks.
Mine had 3miles on the odo. I would have never accepted it knowing that it was driven by a car monkey.

 

I doubt running in cruise would cause any adaptive transmission or engine issues. I had about 20 miles on mine before taking a 400 mile weekend trip and ran cruise most of the way. South of St. Louis, MO to Ozark, MO and back... I-44, county roads, lots of hills, and dedicated slow moving traffic lanes for big trucks. I never had a problem keeping up or passing anyone.

If you're putting the pedal on the floor and it's not getting over 2k RPMs, something is wrong. Granted a 4Runner isn't a race car or a rocket, but it has pretty decent acceleration, even up a reasonable interstate hill. You should be able to easily climb hills and overpasses in Dallas.

Had a thought: could your floor mat be curled up under the gas pedal and restricting its full travel?

 

Is that anything like a trunk monkey?https://youtu.be/XW8iAVwt_Yc

 

So I got an update. Mtbpsych was right about the pre-collision system. When I turned it off, I actually could go faster incline, but It still took time to climb the hill which I guess it's just how the car is. However, I did 0-60 tonight, and I got average 10 seconds instead of average 7-8 seconds as advertisement. The highest rpms the car could reach was 4000 rpms. I dont know if every 4runner has been programmed with different rev limit. One more thing I has noticed was the car jerking when I switch from park to drive or reverse. I will take the car to the dealership tomorrow. It will officially reach 1000 miles by the time I get there.

Hi Friends,
I just purchased a brand new 2024 4runner, and have the same issue: can not more that 100km/hr when uphills in the mountain highway from Vancouver to Edmonton.
Just called Dealer, they said will charge me 200$ to inspect. So ridiculous. as to the low speed uphills during driving on highway, any idea?

 

Did you try using the throttle?

 

Disable it. You don't need an indicator to know that it never would be economical on gas unless tumbling off a cliff.

Funny thing - one of my classic cars has eco indicator. That year, they replaced oil temp dial with this useless indicator. That car maybe gets 15 MPG on a good day. I'd rather have an early warning for overheating.

 

what is throttle? how to use it? Thanks

 

how to turn pre-collision off? my new 4Runner also can not reach 7-8 seconds, maybe 10+ seconds reach 100km/hr

 

Right foot and push more. It will easily go over 100 maple leaves.

 

Pre-collision doesn't do anything unless you're coming up quickly on somebody going slower than you.

 

Hi,

When drive uphill in mountain highway, it is really weak in accerleration and speed is not as fast as other cars, is it because it is heavy (2200KG+)? when I start to drive uphill, i can see other cars is running really fast, more than 100+ km/hr, my 4runner like a old horse, engine sound like exaustively.... Is it normal??? Thanks again

 

The reason I’m asking of you are using the throttle is if you are and you still lose speed and or you are experiencing some vibration then you have an issue. If you aren’t then step on the throttle to pick up speed. These were never designed to be sports cars but can handle some throttle input if you need it. So, are you using the pedal?

 

It is NORMAL having to push accelerator pedal a lot when going up high inclines. You have mechanical issue ONLY if you are pedal-to-the-floor with accelerator and it is still slowing down going uphill. When you press accelerator hard, the car will downshift, RPMs will go high and it may feel like it is lurching forward. All of this is normal and would not damage the car in any way. More so, RPMs getting near red line is fine (unless you neglect oil changes) and not harmful to your engine.

 

It's a pretty noisy engine, and it gets this higher pitched whine when you get above 3000 rpm, but it's normal.

The gas pedal is very gradual, so I find myself giving it up to twice as much pedal as our other car, for reference.

 

Is the sprint booster same as the pedal commander?

 

Both are the same as your foot.

 

Someone mentioned it before but throw it in S4. You can potentially overheat the transmission if you’re pushing it in D (overdrive) on prolonged / steep climbs.

 

The Toyota 4.0 is gutless at elevation. If you live at elevation and drive the passes often you need a vehicle with a more useful power range or if you really love the 4runner you could have lower gears installed in your axles.

 

That’s not a thing. If you leave it in D then the trans would possibly downshift to 4th anyway. That’s all you’re doing by moving to 4th. The converter would unlock in either way.

 

Just reporting from my own experience here and I might be misunderstanding this but I was monitoring all my temps. on a recent trip and noticed if I drove up prolonged steep grades e.g mountain passes in D the temp for the transmission fluid, particularly at the torque converter would quickly climb from the typical 190F upwards to 225F. Not wanting to risk temps rising further I pulled over to let things cool while google researching S mode. I live at sea level so rarely needed to go into S before. And lo and behold to my relief when I started climbing in S4 tranny temps. would literally “freeze” and remain constant around 190-195F. Now I am pretty sure if I kept pushing things in D things would’ve gotten really hot. So glad I hooked up that OBD scan tool for the trip.

 

Scarif is right. Tranny will keep shifting to 5th when you let off the gas slightly (which you'll do when it drops to 4th), then back to 4th when you give it some more gas, and this will heat things up (especially because you'll be unlocked in 5th).

Put it in S4 and remove the option of 5th, and the trans will settle down, usually locked in 4th. Even if it locks / unlocks in 4th, that won't be as dramatic and won't heat up as much.

 

What are you talking about? I drove carbureted cars up Pike's Peak, that is what loss of power looks like. 4Runner is fine. Just use your right foot more.

 

If it got too hot you would have seen an AT temp light. It’s fine. If you’re talking about gear hunting then yes it would heat up and you should downshift but most people don’t.

 

Normal operating automatic transmission temps are up to 225F. Unless you neglect fluid, I would not be pulling over for anything below 275F.

I think people are too used to good times. Cars used to overheat regularly. You can smell it before it happens. If you pay attention, you can also feel and hear it overheating as it starts running differently.

 

Great example. Ive driven three different vehicles up Pikes Peak and my 4.0 5 th gen was an embarrassment. It was struggling right off the bat. Absolutely no throttle response unless you force it to climb at 5000 rpm in 2nd gear. Anyone who thinks that’s just using your right foot isn’t someone I’d care to buy a used car from. I really do think the 4Runner is under geared. Particularly for elevation or regions with twisting up and down roads. The 4.0 needs at least a 4.11 ratio with OEM tires.
I do admit I’m spoiled with most of my drivers having been full-size trucks. Nothing can beat a big turbo diesel when it comes to compensating for elevation power loss.

 

Everyone is on a high elevation kick, but is that even relevant to the OP?
