Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners report two distinct issues. The first—and most frequent—involves engine stalling or shutdown after driving in rain, typically manifesting shortly after parking or during slow traffic. Symptoms include shuddering, "Reduced Engine Power" or "Engine Stopped – Steering Power Low" warnings, and in one case, white smoke from the engine. One owner's vehicle was diagnosed with a P010014 code and MAF sensor replaced per Toyota TSB T-TT-0763-24, which remains under investigation. Multiple owners suspect water intrusion into the air filter and MAF sensor. Dealers have been unable to reproduce the issue or find fault codes in most cases, leaving owners without repairs.
The second issue—rare but severe—involves an engine block crack at 3,600 miles on a 74-degree day, followed by coolant loss at 5,714 miles. No details on cause or repair are provided.
Owners cite seeing similar complaints on Reddit and other forums, suggesting a pattern beyond individual cases. Stalling events have created hazardous traffic situations and near-misses for multiple owners.
