Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.

Same car, a better year

Other midsize pickups with no elevated signal

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.

What owners reported

POWER TRAIN09/08/2026
Driving in town 30 to 40mph, (while in drive) the vehicle rev’d up like it was in neutral then went back to normal. That is concerning because it will cause transmission problems & pulling onto a road the truck could shift to (neutral) causing it to not go.
ENGINE,FORWARD COLLISION AVOIDANCE08/08/2026
Having two issues major issues that’s causing me a $10,000 bill. The timing cover is leaking and there is a coolant bypass hose that is leaking. I have spend a lot of maintenance on this truck on maintaining it to have to remove the engine. As for the forward collision warning ive had it go off multiple times witout a …
ENGINE05/26/2026
The plastic coolant crossover valve or pipe failed at 66,000 miles and 5 years of usage. This led to the radiator cracking. After researching online, I read about thousands of Tacoma 3rd generation users with the same issue. Also, the same issue was recalled for several other models of Toyotas but not the Tacoma.

Three of 28 drivetrain complaints. The full report shows more, with quotes about the engine in the car you are looking at first.
