Check a VINDoes the 2021 Ford Bronco have engine problems?
Owner complaints say yes, as a model-year pattern. 435 of 928 relevant complaints filed with NHTSA about the 2021 Ford Bronco concern the engine, transmission or fuel system (48%), and the largest group is filed under engine (220). For comparison, the 2022 scores 38%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.
Complaints by component
The years either side
Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.
Cleaner alternatives
Same car, a better year
Other midsize SUVs with no elevated signal in 2021
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.

Before you buy a 2021 Ford Bronco
- Ask the seller whether the engine has ever been repaired or replaced, and whether the car has shown stalling, loss of power, rough idle, oil consumption or a check-engine light.
- Drive it from a cold start and long enough to warm up. Many engine 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 engine.
- 35 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 engine already replaced under warranty is a different car from one that was not.

Should I buy a 2021 Ford Bronco?
That depends on the car in front of you, not just the model year. The 2021 Ford Bronco has an elevated engine complaint pattern, so treat it as a car that needs proof: service records showing engine work, a cold-start test drive, and an independent pre-purchase inspection focused on the engine. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
