2019 Tacoma 1500Rpm Diagnosis

If there is an issue with these Tacoma's where many have this same exact thing going on with their trucks? It's not the way I drive? Something isn't right! I can guess, but that's what the engineers at Toyota are for. If we don't speak up to them? They may consider this isn't an issue leaving things the way they are.

The other day after my visit to a local dealership. I told the Toyota tech I believe this is a Toyota problem, not a Toyota Service department problem. Dealership tech's can't fix these trucks if they have no idea where to begin? That's where the engineers come into play. I was told problems that warrant repairs the dealership can't repair, Toyota will send one of their engineers to a dealership for guidance?

I figured I'd gather as much information as I could before contacting the Toyota Customer Service. This forum helps me do that. Toyota has a great track record for standing behind their product. However it's disappointing that it seems so many suffer with this same problem. So, I'll chime in and let Toyota know.

 

I wish it would disappear in ECT? It makes it tolerable, but there is still a miss.

Thanks for your input! Much Appreciated!

 

Was saying that it may be more of a frustration for you based on the way you drive. Not that it doesnt exist for anyone else because we drive differently.

Ive had a 2016 for 2 years and now a 2019 for 2 months. They both drive exactly the same way and I’ve experienced and still do experience what you are describing in both pretty regularly. One of my reasons for getting rid of the 2016 was for this issue. When i was shopping for a new truck just recently i went back to the tacoma because there was nothing better for the price and decided ill just live with how it drives. I have zero regrets about getting back into a Tacoma knowing this is how its going to be. The sooner you accept it, the happier you will be. If not, I think you need to just sell it.

If you want the “misfire” to go away, step on the gas! I know its not the answer you want to here, but their are literally thousands of posts and complaints about this on these forums with hundreds of people going to the dealer and basically if nothing has changed in 4 years, why would it change now.


Now, if you think you are having a different issue, by all means take it up with Toyota, but everything I’ve read suggest its not.

 

By all means, monitor away.
The CEL protocols for misfires are rather robust.
I'd try 91-93 octane and S3 first.
This would eliminate gas and the torque converter

 

Like i said normal for 3rd gens

 

I just called and spoke to someone at Toyota Corporate. I now have a case number and was told to expect a call from my case manager. I understand some may write this miss off as nothing more that a nuisance. And they can accept that?

My way of looking at things is like this. if we went to work and expected our customers to accept sub par work, or sub par operation of the equipment we sold them. How long would we be in business? Not long!

I'm used to dealing with people and problems. My background was in the vertical transportation department. I became a supervisor who had to deal with equipment that didn't work correctly, poor workmanship, intermittent mechanical, circuit boards, electrical problems, and trying to maintain customer satisfaction when things weren't great. Part of my job wasI to gather all of the information I could before contacting one of our sub contractors or equipment providers so I knew what we all needed to fix. We all worked together to get the job right, to keep the customer happy. Thats all I'm doing here!

If by some strange chance? There is a fix for these problems we all seem to deal with? We will all be much happier with our Tacoma and Toyota.

Thanks again,

Great!
Thanks!

 

My '17 has been doing something similar for 42,000 miles. Sounds more like old fashion valve clatter and seems to happen primarily when it downshifts from 6th to 5th. The sound appears to be coming from around the torque converter area. Just this week started going to s4 anticipating the normal downshift and its not doing it. ?

 

Wondering if any more came of this? Having a very similar experience with my truck. I need to get my wheels balanced again to rule that out, but don’t think they’re the issue. Driving me crazy right now. I have 6500 miles and it got worse after about 6000.

 

My truck suffers from this, and I posted in this thread already, but I always recommend trying either a different brand of fuel, or as in my case, a higher octane of fuel. I run 93 for this issue and have almost 47k miles on my truck.

For about $10 you can at least eliminate one variable.

 

Took the truck to a second dealership. They checked it out and actually took the wheels and tires off balancing them! What they found was the brand new tire on the right rear that had just been replaced by the original selling dealership was far out of balance! Although the truck actually rode better, this didn't change anything.

After speaking to people at Toyota Corporate, different dealerships and their techs. What I got from one was, it's the tires, it may be the torque converter? In the end several service departments told me, all of them do this? Go test drive any of them on the lot and you'll see what we're talking about? My feelings were and still are. If this is acceptable to Toyota? It wasn't to me! I got rid of the truck! Truck had just over 3000 miles on it.

With all of this technology while squeezing every bit of performance and fuel mileage out of these new Toyotas. Apparently no one can diagnose and fix them? Including the people who engineer and design them? It's very unfortunate!

All that being said. I traded the Tacoma in on a new 2019 4Runner Limited. Although I'm not happy about how the situation was handled by Toyota or the dealerships I took the Tacoma to. I feel right now the 4Runner was a proven trouble free platform! It's nice to drive down the road and not feel like there is an engine miss.

I know this doesn't help anyone with some diagnostic fix? But it completes my story! At least you know how it ended. Just wished I could have helped find answers?

Good luck to all still searching!

 

I have a manual transmission and my truck has this. I brought it to the dealer and they said it's "operating as expected." It still drives me crazy, though.

 

That is a disappointing outcome. As a former mechanic. There is no way on earth I could have told my customers that it was normal and just accept it.

 

Tried this and not much of a difference, if any.

 

Same.

I had an early 3rd gen M/T (09/15 build), and now this 2019. The stuttering in that RPM range is common.
I don't get any noise, just short hesitations in quick succession. It's worse when the engine isn't up to temp.
