Used Ford Bronco Sport 1st Gen (2021-2024): Buyer's Guide

Every used 2021-2024 Ford Bronco Sport with a 1.5-liter engine is covered by an open fire-risk recall. Ford issued the interim software fix in 2025. As of mid-2026, the permanent hardware remedy — actual fuel injector replacement — is just becoming available at dealers. That changes how you evaluate one of these on a used lot.

The Bronco Sport is a genuinely capable small SUV. The Badlands trim, with its 2.0-liter engine and twin-clutch rear drive unit, has held up well. The 1.5-liter trims that make up the vast majority of used inventory carry a documented safety issue that isn't fully resolved yet. Understanding which engine you're looking at is the first thing you do before anything else.

This Generation at a Glance

The Bronco Sport debuted for 2021 on Ford's C2 platform, the same architecture underpinning the Escape and Maverick. It's a front-wheel-drive-based compact SUV with selectable AWD. There's no second generation yet. The platform runs through at least 2030.

For the 2025 model year, Ford issued a mid-cycle refresh: new front and rear bumpers with wider accessory compatibility, a Sasquatch off-road package added to the Outer Banks trim, SYNC 4 made standard across the lineup, and an Off-Road drive mode added to every trim level. The Badlands also got a 10mm ride height increase. Mechanically, 2025 is not a different vehicle. But it's visually updated and the SYNC 4 infotainment is a meaningful daily-use upgrade.

Used inventory concentrates in 2021-2024. Those are the years this guide covers.

Powertrain and Trim Breakdown

1.5L EcoBoost Three-Cylinder (Heritage, Big Bend, Heritage Edition, Outer Banks)

The 1.5-liter three-cylinder is the standard engine on every Bronco Sport trim except the Badlands. That means it powers the overwhelming majority of used Bronco Sports you'll find. If the listing doesn't say Badlands, assume it has the 1.5L.

This engine produces 181 horsepower and 190 pound-feet of torque through an eight-speed automatic. Fuel economy is rated at 25 city, 30 highway, and 27 combined. Owners running the 1.5L on highway cruises report real-world numbers close to or above the EPA estimate.

The capability story is straightforward: enough for light trails, snow, and wet pavement. The standard AWD system sends power to the rear wheels when the fronts slip. It's electronic and automatic, not driver-controlled. You get five GOAT modes: Normal, Eco, Sport, Slippery, and Sand/Snow. No locking differential. No Trail Turn Assist. No Rock Crawl mode.

The fuel injector issue. This is the defining story of the 1.5L in the first generation. Recall 25S76 covers all 2021-2024 Bronco Sport models equipped with the 1.5-liter engine. The problem: the high-pressure fuel injectors can crack under normal operating conditions. When they do, fuel leaks at high pressure near the turbocharger and exhaust components. NHTSA data shows cracked injectors leaking fuel at rates as high as 19 liters per hour. Ford confirmed underhood fire incidents related to this condition.

The original recall (22S73) was issued in 2022 and has since expanded three times. The current campaign, 25S76, covers approximately 858,000 vehicles across 2021-2024 Bronco Sport and 2020-2022 Escape models. As of mid-2026, the interim remedy is a powertrain control module software update that detects a cracking injector and reduces fuel pressure and engine output to lower fire risk. The permanent remedy — physical injector replacement — is scheduled to begin at dealers in July/August 2026. Any used 1.5L Bronco Sport you're considering needs a VIN check against this recall. Confirm the interim software fix was applied. And ask whether the final hardware fix is complete. If not, it needs to be done before you drive it away.

Owners on BroncoSportForum.com have followed this issue since 2022. Forum consensus: the software update reduces the fire risk but doesn't solve the root cause. The hardware fix is what actually replaces the suspect injectors.

Oil dilution. The 1.5L uses gasoline direct injection. At cold operating temperatures, particularly during short trips, some fuel passes the piston rings and mixes with the crankcase oil. Owners monitoring oil levels report mild but real oil level increases between changes. It's not a recall item — it's a characteristic of this engine design — but it means running oil changes on schedule matters more here than on most engines. Ford recommends every 7,500 miles or six months.

Rear drive unit chatter. Early 2021 and some 2022 Bronco Sport models with the 1.5L engine (built before November 30, 2022) shipped from the factory with either contaminated rear drive unit fluid or insufficient RDU fluid. The symptom is a chatter or shudder from the rear of the vehicle during low-speed parking-lot turns. Ford addressed this with TSB 23-2335, which calls for draining and refilling the RDU with Motorcraft XY-75W-QL fluid and replacing the vent hose. A later bulletin (25-2351) allows dealers with special equipment to service the clutch pack directly. If you're buying a 2021 or early 2022, check whether this TSB was performed.

Transmission behavior. The eight-speed automatic has a documented habit of soft or hesitant downshifts, occasional hard 1-2 upshifts, and low-speed shudder in some builds. It's not catastrophic, but it's consistent enough that forum threads specifically about the transmission go back to 2021. During a test drive, run repeated low-speed accelerations from a stop and a few parking-lot stop-and-go sequences before drawing conclusions.

12V battery recall. Recall 24S24 covers 456,000 Bronco Sport models from 2021-2024. The body and powertrain control modules may fail to properly manage the 12-volt battery, potentially leaving the vehicle unable to restart after an auto-stop event or stalling at low speeds. The fix is a software update, done free at dealers.

2.0L EcoBoost Four-Cylinder (Badlands, First Edition 2021)

The 2.0-liter four-cylinder is exclusive to the Badlands trim across the 2021-2024 model years. The 2021 First Edition, a launch-year-only special, was built on the Badlands and came with the 2.0L. If you find a First Edition, it's mechanically a Badlands.

This engine makes 245 horsepower and 275 pound-feet of torque through the same eight-speed automatic. Fuel economy drops to 21 city, 27 highway, 23 combined. The additional 64 horsepower makes a noticeable difference for highway merging and towing — the Badlands is rated to tow 2,200 pounds versus 2,000 pounds for the 1.5L trims.

The 2.0L Badlands adds the Twin Clutch Rear Drive Unit, which distributes torque more precisely between the rear wheels. You get seven GOAT modes including Mud/Ruts and Rock Crawl. Trail Turn Assist brakes the inside rear wheel through sharp switchbacks. A driver-controlled rear differential lock engages for deep mud and rock situations.

The 2.0L is not covered by the fuel injector fire risk recall. This is the most important reliability distinction within this generation. Forum data, Consumer Reports data, and NHTSA complaint volumes all show the Badlands with the 2.0L performing meaningfully better than the 1.5L trims across the 2021-2024 model years.

RDU chatter on early Badlands. The same rear drive unit chatter issue affects 2.0L models built before February 28, 2022. Same symptom, same fix: TSB 23-2335, drain and refill with the correct fluid. If you're buying a 2021 Badlands, confirm this has been done.

What owners say. Owners on BroncoSportForum.com and r/BroncoSport consistently describe the Badlands as the trim that delivers on the Bronco Sport's off-road promise. The off-road capability gets credit from owners who take it on moderate trails. The engine feels right-sized for the vehicle in a way the 1.5L doesn't quite achieve on highway on-ramps.

Trim-Specific Notes

Heritage (base): Entry point. 1.5L, cloth interior, basic feature set. Available used in large numbers and least expensive, but the no-frills equipment means checking features carefully — no heated seats, basic audio.

Big Bend: The volume seller. 1.5L, adds alloy wheels, better interior materials. Standard AWD. Reasonable used value. Still carries all the 1.5L issues.

Heritage Edition: Style-focused variant introduced as a retro-themed option. 1.5L. Comes with distinctive two-tone paint schemes and specific badging. Not an off-road upgrade over Big Bend.

Outer Banks: Upper end of the 1.5L range. Adds leather-trimmed seats, SYNC 4 (on 2024 models), comfort and tech features. Does not add off-road hardware. The Standard AWD system here is the same as on Big Bend. Paying more for Outer Banks gives you interior upgrades, not trail capability.

First Edition (2021 only): Badlands-based launch trim with unique cosmetics. Mechanically identical to the 2021 Badlands. Worth the same evaluation as a Badlands. These command a slight premium on the used market but are not mechanically superior to a standard Badlands.

Badlands: The trim worth the price premium for two specific reasons: the 2.0L engine and the Twin Clutch Rear Drive Unit. If you want the Bronco Sport's off-road credibility and a significantly better reliability track record, the Badlands is the one to buy. It costs more used, but the fuel injector recall exemption alone makes it worth considering.

Which Model Years to Target Within This Gen

2021: Consumer Reports gave the 2021 a one-out-of-five reliability rating. First-year production had the most concentrated set of issues: launch-year RDU problems on early builds, the fuel injector recall from the beginning, the most NHTSA complaints of any year in this generation, and documented transmission calibration issues. The 2021 Badlands has a better track record than the 2021 1.5L trims, but it still carries early-production risk. Skip the 2021 unless the deal is extraordinary and a pre-purchase inspection covers all recall status.

2022: Reliability improved slightly to 2/5, but the 1.5L fuel injector issue was still evolving and the complaint volume stayed high. RDU issues were largely fixed on builds after November 2022, which means 2022 models built in late 2022 (September production onward) missed the RDU problem. If you're considering a 2022, decode the build date from the door jamb sticker.

2023: The 2023 is where the Bronco Sport stabilizes. The reliability rating holds at 2/5, but the complaint distribution is less severe. Most of the transmission calibration issues from 2021-2022 had been addressed in production. The 1.5L fuel injector recall still applies, but owners who had the interim software fix applied report no ongoing issues. The 2023 is acceptable if the 1.5L recall status is confirmed clean.

2024: The sweet spot for used buyers. A 3/5 reliability rating, the fewest recall campaigns of any pre-refresh year, and SYNC 4 on more trims. The fuel injector recall still technically applies to 2024 1.5L models, but the 2024 has the lowest complaint volume in the generation. The 2024 Badlands is the generation's best used option overall.

Pre-Purchase Inspection Checklist

All Trims

• Check recall 25S76 status first. Run the VIN at /tools/recall-lookup or the NHTSA VIN tool. Confirm the interim software fix (PCM update) was applied. Ask whether the final hardware fix (injector replacement) is scheduled or complete. This is non-negotiable for any 1.5L model.
• Check recall 24S24 status. The 12V battery management software recall affects 2021-2024 models. Confirm it was addressed.
• Cold start test. Start the vehicle before it warms up. Listen for any rough idle, hesitation at idle, or unusual fuel-smell coming from the engine bay. A fuel smell at startup from a 1.5L is a red flag pointing to the injector issue.
• Battery health. Ask the dealer or seller to run a battery health test on the 12V battery, especially on 2021-2022 models.
• Infotainment check. Run SYNC through all functions: navigation, Bluetooth, Apple CarPlay or Android Auto, audio. SYNC 3 systems on 2021-2023 models have documented freeze and reboot issues. Factory updates resolve most, but confirm the system is on current software.
• Low-speed turns. In a parking lot or driveway, make several slow, tight turns in both directions. Listen for a grinding, chattering, or shuddering feeling or noise from the rear. That's RDU fluid contamination and needs service before purchase.
• Transmission behavior. Make repeated stop-and-go accelerations from 0-30 mph. Any harsh bang on the 1-2 shift, or a shudder on light throttle below 30 mph, warrants a conversation about TSB history.

Badlands Specifically

• RDU check on 2021 builds. Check the build date on the door jamb. If built before March 2022, confirm TSB 23-2335 was performed (RDU drain and refill). Ask for service records showing the Motorcraft XY-75W-QL fluid was used.
• Highway test drive. Drive 35-55 mph with varying throttle. No harmonic resonance or vibration from the rear on steady throttle.
• Trail Turn Assist test. On a loose surface or a slow, tight turn, engage Trail Turn Assist and verify the inside rear wheel braking function is working (you'll feel the turn tighten significantly). Non-function points to a rear drive unit or software issue.
• Differential lock. Engage the rear differential lock at low speed on a loose or uneven surface. Verify engagement via the dash indicator. Disengage and confirm normal AWD function returns.

Running Costs

Both engines reach spark plug replacement at 100,000 miles. Coolant change is also at 100,000 miles. Average annual repair and maintenance cost across the generation is roughly $1,100 per year, though 2021-2022 models trend higher due to recall-adjacent repairs.

The RDU fluid service (TSB 23-2335), if needed on an early build, runs $150-$250 at a dealer. Do not skip it — the alternative is a clutch pack replacement that runs $1,500 to $2,500.

FAQ

Is the 1st gen Ford Bronco Sport reliable? It depends entirely on the engine and year. The 2.0L Badlands has a solid track record. The 1.5L trims from 2021-2022 had significant reliability issues and are still living with an unresolved fire-risk recall on the fuel injectors. The 2023 and 2024 1.5L models are more acceptable, but the recall hasn't been permanently fixed on any of them as of mid-2026.

What year Ford Bronco Sport should I avoid? Avoid the 2021. Consumer Reports rated it one out of five for reliability, and it has the highest NHTSA complaint volume in the generation. The fuel injector recall, RDU chatter, transmission calibration issues, and 12V battery problems are all concentrated in first-year production. The 2022 is only marginally better.

Which Bronco Sport trim is most reliable? The Badlands. The 2.0-liter engine is not affected by the fuel injector recall that covers every other trim. The Twin Clutch rear drive unit, while it had early-production fluid issues, is a more robust system than the standard AWD. You'll pay more for a used Badlands, and the fuel economy drops, but the reliability argument is real.

Does the Ford Bronco Sport have a fire risk? Yes, specifically the 1.5L models from 2021-2024. Recall 25S76 documents confirmed underhood fires caused by cracked fuel injectors leaking fuel near the turbocharger and exhaust. The interim fix is a software update to reduce fuel pressure if a crack is detected. Hardware injector replacement — the actual fix — is just becoming available at dealers as of summer 2026.

How long does a Ford Bronco Sport last? Owners with Badlands models and attentive maintenance report 100,000-plus miles without major mechanical failures. The 1.5L trims, if the recall history is clean and oil changes are on schedule, can reach similar longevity. The concern isn't engine wear — it's whether the recall-related issues are resolved before something more serious happens.

Bottom Line

Buy the 2024 Badlands if you can find one at the right price. The 2.0L engine is exempt from the fuel injector recall, the twin-clutch AWD delivers real off-road capability, and the 2024 has the fewest first-gen issues of any pre-refresh year. It's the version of the Bronco Sport that delivers what the badge promises.

If budget puts you in a 1.5L model, target 2023 or 2024, confirm the recall 25S76 hardware fix has been completed, and verify the RDU fluid service is done on anything built before late 2022. Run every VIN through a recall check. CarScout members can set alerts on specific Badlands trims and years to catch price drops when they hit the market at usecarscout.com.
