2023 Platinum Hybrid Tranmission Shudder?

Sorry for the late response. I wish I had better news. I have not heard back from the dealership for about 1-1/2 weeks. The last time I spoke with them they said they were still working with Toyota for the approval of the electric motor. Too much time has passed, and I do not believe it should take this long, so I'm afraid the battle is still not yet over. I'm fixing to call them to get an update. I will update you. I do not have anything in writing regarding what was verbally said to me about Toyota resolving the shuddering issue by replacing the electric motors, so I can't help with that, and I'm doubtful I will ever get that in writing. Perhaps the service paperwork will provide sufficient information, but I'm not quite there yet.

 

I have a 2022 Toyota Tundra Hybrid. I've been through everything with Toyota to try to resolve the issue - They had my truck for over 8 months. I've had pretty much everything you can think of replaced, Then finally the Toyota Tech came down and said it was "Normal" - By this time, I've had the Electric Motor Replaced, Rear Diff, Controller & even the Transmission itself... The problem is still there and I'm Canadian, So I couldn't even lemon law the truck if I wanted to...

 

Shorr92, the fact that you had everything replaced, specifically the electric motor, and the shuddering issue still persists is highly concerning. Somebody in a previous post stated that they too had the electric motor replaced, and they ended up having Toyota buy the truck back. As far as I know, so far two people on this thread had the electric motor replaced, and it did not resolve the shuddering issue. I called the dealership last week, and they said that they were still working on it. I may have jumped on the Toyota bandwagon at the wrong time. This may be a long drawn out battle with no happy ending.

 

I'm updating everybody on my shudder issue.

I brought the truck to Keene Toyota in Keene, NH, three times. On the third time, they acknowledged the issue. They asked to keep the truck overnight for a Toyota Field Service engineer to inspect it. Upon inspection, Toyota said that they were aware of the issue, that it was software-related, that there was no fix available at this time, and that they were sorry for the inconvenience.

At this point, I contacted Toyota Brand Engagement. BTW these people are pretty much useless. You are talking with someone of mediocre intelligence who is trained to tell people no. This effectively got me nowhere.

So here I sat with my shudder getting worse. I was disappointed with Keene Toyota, so I brought it to another dealership, McGhee Toyota of Claremont, NH. McGhee also acknowledged the issue and opened a Toyota Engineering Dealer assistance case. Fast forward a few weeks, and I have heard nothing; the truck is now shuddering like crazy. I brought it back to McGhee Toyota...where it sits for the next 50 days. During those 50 days, a Toyota Field Engineer finally showed up after rescheduling. Again, Toyota acknowledged the issue and told me it was software with no current fix. This time, they conveyed that this issue is relatively rare, so Toyota engineering cannot repair it. In other words, the more cases that get acknowledged, the more likely they are to do something. It was also noted that modification of the software, mapping, etc, would require EPA approval, or so they claim. Seemingly, a drawn-out process as they depict it.

I have filed a lemon law complaint and have been notified by the State that my vehicle qualifies for arbitration. I picked the truck up from the dealer; they had reset the TCU etc. It ran great for a couple of hundred miles and is shuddering again. I would guess one of these aftermarket tuning companies could fix it for good. For myself, I am going to run the lemon law out and hope I can force them to buy it back. If that fails I will likely try a tune like all the 3rd-gen Tacoma guys did to fix slamming transmissions. Pretty disappointing for a 78k truck.

 

They know they have an issue. It is well documented internally, but they aren't going to say that. There is a reason they are asking for TAS case creation on the hesitation issue (T-TT-0777-25) as well as the rattle while stationary (T-TT-0775-25).
