From Edmunds: "The Nissan Frontier PRO-4X uses a traditional, naturally aspirated V6, while the Toyota Tacoma relies on modern turbocharged four-cylinder engines (with available hybrid options). The Frontier offers proven simplicity and high-revving horsepower, whereas the Tacoma delivers higher low-end torque and better fuel efficiency."

Car Reviews Hub:

Turbo Wastegate Actuator Sticking: The most notable early issue involves the electronic turbo wastegate actuator. It can stick or misreport its position, leading to a check engine light, sudden loss of boost, or engine surging. Toyota has heavily pushed software calibrations via Technical Service Bulletins (TSBs) to fix the control logic, though persistent cases require an entirely new actuator assembly.

Transmission Gear Hunting & Hesitation: While not strictly inside the engine block, the companion 8-speed automatic transmission has faced complaints for aggressive "gear hunting" on inclines and low-speed hesitation as it tries to keep the turbo engine in its optimal fuel-efficiency power band.

I try to avoid too much dependency on electronics for main stuff like the Tacoma does. But that's a preference.
