2018 Toyota Tacoma: engine and transmission complaints
HIGH COMPLAINT SIGNAL
42%
83 of 203 relevant owner complaints are about the engine, transmission or fuel system
42% of relevant owner complaints filed with NHTSA on the 2018 Toyota Tacoma are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 50% of the 1,230 model years we track (2010–2023).
The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2018 Toyota Tacoma
Ask the seller whether the fuel system has ever been repaired or replaced, and whether the car has shown hard starts, stalling, hesitation, a fuel smell or a check-engine light.
Drive it from a cold start and long enough to warm up. Many fuel system faults hide once the car is warm.
Get an independent pre-purchase inspection from a mechanic you choose, and tell them to focus on the fuel system.
3 recall campaigns on this model year. Whether a specific car still has one open depends on the VIN; the report checks that.
Ask for service records. A fuel system already replaced under warranty is a different car from one that was not.
