2019 Tacoma 1500Rpm Diagnosis

S mode isn’t “sport” mode... read the manual. S mode is a transmission gear shift limiter... i.e., if in S4, the transmission will be in a fixed (not learned) standard programmed gear shifting mode from first to forth... if S5 then from first to fifth, and so on. Main function is to keep the transmission from going into overdrive when towing (use S4 in that case).

 

Dude.....it’s a normal condition of the Atkinson’s calm down and google that shit

 

the only thing that's not normal it appears- based on my test drive of 3 brand new tacos with the v6- is the knocking. perhaps the OP got bad gas? It happens. As far as the stuttering, as far as I know they all do it at low rpms unless all 3 i test drove and the one i bought, are all "defective" in some way. watching and waiting for a tsb/deeper dive thread on this.

 

Interesting, my truck has never exhibited these issues as articulated by the OP. Sorry, but for a brand new truck, I’d prefer to have the dealership look at it and inform me as to what’s happening (nothing against your “at home” diagnostics).

 

It has, but either you haven’t noticed it, or you don’t consistently drive in that part of the power band.
My truck been knocking under those same conditions before you owned one

 

Too bad for you... I would sell my truck if it started doing what the OP described and you say is normal.

 

first, my recent experience with FORD

i bought a brand new ford mustang GT pp1 in late 2018.

That thing ticked at idle- like a typewriter- and rattled at 3500-3000 rpms.

dealer said all normal and ford came out with a tsb in February stating its a normal characteristic of the 5.0.

I thought about getting them to say that 3 more times them lemon lawing it but life is too short. I decided to trade it for the taco. The stang was a not too smart choice for me but live and learn. I didn't lose that much in the scheme of things.

I test drove 3 tacos all of which did the low rpm stuttering thing. I picked the one that did it less per my butt dyno.

I chose toyota tacoma because

1) toyota reliability
2) lifetime power train from dealer that is honored at all affiliated dealers- they have many across the USA.
3) pickup would be nice to have
4) i could have gotten a jeep but with my experience with them/dealers at least around here, i chose the toyota
5) everybody has a jeep
6) looks sweet
7) i could have gotten a 4runner BUT they are worse with MPGs and i already have 2 SUVs in the garage.


I chose the tacoma for the reasons above after test driving one AND experiencing the stuttering. If it croaks on me i have warranty at least for next 5 years or 60k miles and probably beyond.

I am not too worried.


Now if it's knocking noticeably, take it in!!!

 

I think you are all getting hung up on his term of knocking. While he says knocking, what he is clearly describing is the stuttering/jerking issue all these trucks exhibit in the low RPM range.

 

ahhhh i gotcha. yeah if he means knocking as in a jerking/movement type and not a noise, then yes, his is like the rest of ours it seems

LOL

 

drove last night on a pizza run- about 10 miles roundtrip. I love the ECT PWD ON! It seems way way more responsive and zero bucking.

from now on, i will drive with it on unless i am on the flat highway for a long time.

i think i may have lost .5 mpg. Hard to tell though on such a short trip. The cluster read 19.5 mpg average. Which isn't bad at all IMHO. The roads are 2 lane backroads most of the way.

 

Majorly disappointed with the 2019 Tacoma right now. The engine has a miss! On the 17th of June I took it in to address this issue. When the Service department came back with. The tech felt the miss, but suggested it could be due to the road I was traveling on?? Why at 50 MPH in drive does it do this all of the time? No matter where the road is?

No! I didn't feel this when I test drove it. And it really didn't show up until after a few hundred miles of ownership. The truck now has 2000 miles on it.

I have a 2018 Highlander that rides and runs smooth as glass. I also have a 2012 Tundra with the 5.7 engine that I absolutely love. But the Tacoma has some kind of issue that doesn't throw an engine code.

I'm taking it back in tomorrow for a rear tire. While I'm there I'm going to let them know not to send me some form asking how they did? Because the issue isn't resolved, and so far, no one has offered any info or seems to care about a new vehicle having issues. No TSB's no ideas?

Toyota's good name while standing behind their product has been a major point for me as to why I buy their products. Unfortunately this Tacoma engine miss issue will put their dedication to their product and customers to the test. I believe they'll fix the issue. It remains to be seen how long it takes?

 

I would take it to the dealer, end of story. But, out of curiosity, I would also reset the ECU by removing the neg battery cable for about a min and see if that makes any changes.

 

I guarantee the miss u have is "normal" for these trucks. But by all means, complain. It needs to be addressed and they can do a ecu reprogram to address it but until enough complain, they wont.

 

Normal for third gens

 

What drivability issues are u experiencing?

 

Thanks.

 

Drivability issues. Tacoma is a 2019 TRD Sport with 2100 miles on it. Since I've owned it while driving at 50 mph in drive without using the ECT button it acts like it has an intermittent miss. When I first started driving it, the miss wasn't as bad. After about the first 1000 miles was shown, it started becoming really annoying! The issue doesn't seem to be what is known as Bucking, but is more in line with an intermittent miss.

If I use the ECT Button? The miss isn't as pronounced, but it's still there. The tach at 50 mph without the ECT Button pushed shows a RPM of 1100 to 1200. With the ECT the tach shows near 2000 rpm at 50 mph.

I went through this with the tech. He came back saying although he felt the miss, he also thought it might be road vibrations due to the stiff suspension?

I think (I got the customer service number for Toyota from the dealership) the main issue is related to Toyota trying to squeeze everything they can for better fuel mileage? In doing so, for the transmission to be in 5th gear with 1100 rpm showing at 55 mph may be a tad too much for everything to operate as it was designed? I'm going to call to see when one of their factory tech's visits in the Washington DC, Southern Maryland area.

My big concern is why do I still feel a slight miss at 2000 rpm's at 50 using the ECT? I was thinking about using my scan tool while driving the truck to see if their are any indications of a mis-fire? but, if there was? It should show up as a CEL?

Any suggestions or ideas are more than welcome?

Thanks, Silverstreek

 

For anyone with this same issue concerning an engine miss who would like to contact Toyota Customer Service?

1-800-331-4331 is the number I was given by my local Toyota Dealership. Maybe if enough calls are placed asking about drivability issues concerning the Tacoma? We may get answers sooner than later.

Lets hope so?
Good Luck!

 

So, does anyone with a 3rd gen auto not experience this issue? What you are explaining seems like pretty much what we all experience from time to time. I hardly ever drive in the 50-60 mph range (most of my driving is 35 and below and than 65-80). Maybe it is more pronounced for you due to the way your drive, but id be lying if i didnt feel this “miss” at least once during some part of my daily commute.

 

I'd say if it goes away in etc it could be torque converter lock up.
