Ford Bronco Sport
Ford's three-cylinder turbo, 1,497cc, 181 hp (135 kW). Evolution of the 1.0L Fox three-cylinder — first with cylinder deactivation and combined port/direct injection. All-aluminum block, integrated exhaust manifold. Three-cylinder vibration noticeable at idle. Massive recall for cracked fuel injectors (fire risk) — check recall status before buying. Fuel dilution on short trips is real, shorten oil change interval to 5,000 miles if mostly city driving. 8F35 transmission can shudder, PCM update helps sometimes.
Baby Bronco = Escape in off-road clothing
The Bronco Sport is not a Bronco. Same C2 platform as the Escape IV, different clothes. The 1.5L three-cylinder turbo has a distinctive thrum and gets the job done in daily driving. PTU overheats off-road, fuel injector recall covers nearly all model years, paint is thin like all Fords. Capable on gravel roads and forest trails — for real terrain, get the full Bronco or the Badlands.
Engine Weaknesses 5
Recalls 22S73/24S16/25S76: Fuel injectors can crack and leak up to 19 liters per hour into the cylinder head. Fuel travels onto hot engine surfaces — fire risk. 858,000 vehicles affected. Ford flashes updated engine software as interim fix that detects fuel rail pressure drop.
Symptoms: Fuel smell in engine bay, reduced engine power, check engine light
Coolant enters combustion chambers — reported on some three-cylinder engines from around 60,000 miles. Symptoms mirror the older four-cylinder issue, but root cause on the Dragon I3 is less documented. Turbocharger may sustain collateral damage.
Symptoms: Coolant loss without visible leak, white exhaust smoke, rough cold start, misfires
8F35 automatic transmission shudders on shifts between 20 and 40 mph. Torque converter or shift solenoids may be at fault. PCM software update (TSB 21-2281) resolves it for some vehicles, persists for others.
Symptoms: Shudder/judder at 20-40 mph, delayed shifting, vehicle feels like it will stall
Wastegate control solenoid or boost pressure regulation fails — boost becomes unstable, engine enters limp mode. Code P0299 (underboost) typical at higher mileage.
Symptoms: Power loss under load, check engine light (P0299), limp mode
Direct-injection-typical fuel dilution in engine oil — especially with frequent short trips. Oil level rises, oil smells of gasoline. Shortened oil change intervals of 3,000-5,000 miles recommended for predominantly city driving.
Symptoms: Oil level rises above maximum, gasoline smell on dipstick, thin oil consistency
Vehicle Weaknesses 10
Power Transfer Unit (PTU) overheats during off-road driving — even the Badlands with liquid-cooled PTU. Vehicle enters limp mode, AWD temporarily disabled. Vent hose design flaw allows debris to contaminate differential fluid.
AC compressor seizes without warning — serpentine belt snaps, engine overheats. Ford acknowledged roughly 13-14 complaints in early production. Also reports of weak cooling performance in high ambient temperatures after 30-60 minutes of operation.
Recall 21S04 (NHTSA 21V075000): Rear subframe bolts may be loose or missing. Only 1,666 vehicles affected, built July-November 2020 at Hermosillo plant.
Recall 24S24 (NHTSA 24V267000): Body Control Module and PCM cannot detect declining 12V battery performance. Vehicle may fail to restart during Auto Start-Stop or stall at low speeds.
Rear differential chatters during low-speed turns. Cause: contaminated diff fluid, sometimes underfilled from factory. Drain-and-refill with a 5-mile break-in drive usually resolves it.
Panoramic roof seals leak — water intrudes into the cabin. Especially common on 2021 models. Seal rubber deforms due to manufacturing tolerances.
Rear tailgate window leaks due to faulty seal or bent defroster wires pushing the glass out. Water collects inside the liftgate and corrodes mounting brackets. Out-of-warranty repair up to $1,350.
SYNC 3/4 infotainment screen goes black or freezes. APIM module can be bricked by failed OTA updates. Hard reset (hold volume + right-seek button) sometimes recovers it, otherwise APIM replacement needed.
Rear brake pads wear drastically faster than fronts — some vehicles down to metal under 10,000 miles. Dry caliper slide pins prevent proper caliper float, holding pads against rotors.
Ford-typical thin paint — rock chips down to bare metal within the first few thousand miles. Hood leading edge, fender fronts, and grille area worst affected. A factory plastic tab on the grille rubs additional paint off.
