Finally a fix from Toyota for Stumble condition (TSB 0062-18)

Just want to confirm this is the new software Cal-id# and its on my truck? After picking my truck up, the dealer said something about they didn't have 0062-18 to update to but did another update and couldn't give me the TSB rev #. Honestly Disappointed if this is the correct update, nothing really changed on my truck IMO,

 

yep, 04B04

 

Haven't been on here in weeks.That is exactly what it does. Some of the hills on the way to my house are at least a 60 to 70 degree incline. And the trac control symbol lights up. It's the actuator I'm told. Dealer is in a "flat" town. If I go light throttle, no issue. THANK YOU

 

I got the updates installed on my truck transmission and engine when the truck had 100 miles. I have been informed that after this updates are installed on the ecm the truck is now good for premium fuel 91 octane or better only. Are the people experiencing problems staying on premium fuel? There is a big difference in how the truck runs now compared to the way it was before the reflash. The hesitation is gone and the transmission is fixed about 85% of the time.

 

I have 30k miles on my truck, 22k miles or so on 93. No issues. Why would there be?

 

Because the new software uses timing advance to help with the lack of power- this requires decent fuel because if not detonations happens which will tell the vehicles computer to pull timing and then it could be sluggish again. I was told 5 tankfulls is when the ecm takes full advantage of the new program. I’m on my second tankful of premium and I am happy with how it runs

 

I doubt 91 or better is required now. This would be the first I have heard that. I'm still confused on why there would be any negative effect of running premium long term.

 

Just had this done and it’s the real deal! I suggest if your doing anything to your truck this update should be your number one priority!

 

Zero negative effect on running premium long term. I misunderstood your question. I have been using nothing but premium on all my vehicles.

 

I keep seeing these types of posts....2k miles later and mine drives the exact same way when I got the TSB done.

 

Agreed. I’m getting a bit frustrated at this point. I love my truck but I don’t, if that makes sense. Like many, this is not my first Taco rodeo but Toyota needs to pick up the quality.

FWIW, I drove an OR and Limited T4R this weekend and the OR had the same wobble my second gen had when it was new. The salesman tried to pull the unbalanced tire or flat spot excuse so I just kept driving. It never got better. My second gen didn’t either until years of fighting with Toyota and basically replacing lots of suspension items. The Limited drove better but the steering was way off center and it had the same driveline vibration my second gen was plagued with. Another thing I noticed was the 4.0 is just as I remembered. So many recall it as if it was the best thing but it was weak to me, just like my second gen was, and I don’t view that as a favorable experience, at least not until a couple of years of adjustments.

I also drove the VW Atlas and Subaru Ascent afterwards and the Subie drove like a luxury car compared to the T4R. I know we are talking unibody vs frame on body. The VW was church pew quiet but the steering was a bit over compensated. There is no way I would spend the money for the T4R for my wife after driving other vehicles that made it feel like a 20 year old truck. I’m sure the T4R is a fine vehicle but not for me as a family vehicle. I’d drive it myself if I didn’t want a truck but that thing needs updating sooner than later. Toyota needs to update their lineup as they are well behind in my book. That infotainment system was straight up tiny and glitchy (like my Entune is glitchy) on the T4R.

I’m not trying to dump on the T4R, but after driving a lot of SUVs from a few different manufacturers, it’s clear to me that Toyota has gone well past it’s expiration date for updates. They need a fresher lineup now, not later. If Toyota put the time and effort into keeping the trucks and SUVs updated that they did for the Camry and Corolla, they’d be unstoppable. As it stands, they are well behind to me.

 

I don’t agree with your assessment of the 4runner or second gen Tacoma, but you are bitter so I don’t blame you. My 2016 4runner is smooth as silk. Wish I had my 2013 Tacoma back.

 

I have to disagree as well. The 4Runner might be used as a grocery getter but that isn't its intent or design philosophy. Does the off-road 4runner have KDSS? I am not updated on the recent trim changes.

 

Nope, I’m not bitter at all. Like you said, you disagree and that’s ok. I’d never buy a new vehicle that has that much vibration in it, not again. I did once and it took two years of arguing and debating to get it fixed, but it was finally fixed. Not agreeing on a vehicle is ok and that is why there are so many choices out there and I’m ok with that.

I love my truck but get irritated with the howling and neurotic shifting issues. I still plan to keep it, still like it, still wheel it, and will do my best to ignore the whining/resonance issue. There is no other truck that I like more. If there was I would buy it. But, it shouldn’t do this and we all know it. Looking back I wish I had driven the truck harder during the relearning period because I’m thinking maybe the truck would have learned to hold the gears longer like it did right after the flash. I drive too slow and likely drove it too much like a grandpa. I could be wrong but do wonder if the truck just doesn’t do well when you drive for economy. The tech at my local dealer told me no matter what I did this truck would always stumble when driven easy. So far it looks like he is smarter than I thought he was.

As for my second gen Taco, it turned out to be an excellent truck but geez it had a lot of issues early on. A lot. I preferred it at lower speeds but that’s it.

I’d drive the T4R any day for my daily driving in place of a truck. But, I wouldn’t want it as a family vehicle, not when we don’t use our family hauler to off-road in. If we did, I’d accept it for what it is and likley love it.

 

I agree with your assessment. I was looking for a family vehicle and that grocery getter and it turns out the T4R wasn’t for me. Like I said earlier, if I didn’t have a truck, I’d gladly drive it, but we don’t off-road our family hauler. If we did then I’d likely opt for the Land Cruiser. It drove very nice in my opinion. Yes, the T4R had KDSS if I recall correctly. It looked fantastic but really does need a better and bigger infotainment option. I wonder why they couldn’t put the one from the Land Cruiser over in it, but I’m sure it would require a dash redesign. I bet an updated model is likley in the pipeline.

 

I went to a dealership named Putnam Toyota in Burlingame (California) to try and get the TSB 0062-18 dealt with. Even after giving them all the keywords "stalling" in "high altitude", plus a print out of the TSB, they told me they can't upgrade the ECM due to them not being able to recreate it.

They won't even work on a rattle in the headliner without being able to recreate it!

 

That’s a bummer but I’d try another dealer. My dealer was great about it but they did say they had to duplicate it. They did but they had to do it under the TSB 0058-18 (they said that met my symptoms better) and I was fine with that since it is the same update but for different reasons.

 

2020, new body style and power plant.

 

I’d almost buy the current one if the infotainment system was bigger and better. I liked it for me and am certain something was wrong with the OR I drove. But the Subie was far smoother as a family hauler. As you pointed out, the T4R is purpose built and that’s not it primary purpose. I look forward to seeing what the bring in 2020.

 

Did you get the diff howl TSB done? I guess I am just fortunate; I have yet (26,500 miles) to have rear end or front end (body mount bushings) noise.
