The failure pattern owners describe
Buyer takeaway: 2021 CR-V owners report engine misfires with water sounds (blown head gasket concern), fuel injector failures causing stalling and power loss at highway speeds, CVT leaks, unexpected power loss requiring restarts, rear differential cracks, mysterious speed drops, brake and transmission control failures, and sticky power steering. Multiple owners say Honda has refused warranty coverage or goodwill repair despite citing the same failures in service bulletins for earlier model years.
Owners of 2021 Honda CR-V report multiple distinct powertrain failures. Several complaints describe rough engine operation and check engine lights, with one owner citing a P0302 cylinder 2 misfire code and water-sloshing sounds suggesting internal engine damage. Another owner encountered a fuel system issue with P0172 (bank 1 too rich) and P219F (cylinder 4 air-fuel ratio variation) diagnostic codes, leading to gas smell and stalling; they cite Honda Service Bulletins and Manufacturer Communications for the same failures on earlier model years but claim Honda refused warranty extension despite the known defect.
Transmission and drive system issues include a CVT housing leak causing transmission sluggishness and power loss, a rear differential that cracked at highway speed with no apparent external damage, and reports of the vehicle losing engine power while driving (check engine light appearing) that resolved only after shutdown and restart—happening multiple times over months. One owner reports inadvertent reverse engagement at 5 mph with instrument cluster blackout and brake failure, though the dealer could not reproduce it.
Unrelated to engine/transmission, an electric power steering (EPS) gearbox exhibited sticky steering on turns, worsening over time, requiring replacement per dealer diagnosis. A shift cable detached after the owner repeatedly hung a placard on the rearview mirror, stranding the vehicle in park. Oil level rose above the dipstick mark with gasoline smell present.

Failure modes owners describe
Engine misfire and internal coolant/oil mixing
Engine rough operation and check engine light (flashing, indicating severe misfire). Owner reports water-sloshing sounds and rough starts on restart cycles, consistent with blown head gasket or internal failure allowing coolant into combustion.
When: Occurred while ascending steep hill; vehicle has 70,000+ miles at time of incident
Symptoms owners cite: Rough engine operation; Flashing check engine light; Water sloshing sound; Rough restart/startup; Loss of power risk on hills
Codes mentioned: P0302
Recalls/TSBs owners mention: Owner references NHTSA Preliminary Evaluation PE25016 and Bissell v. American Honda Motor Co., Inc. lawsuit. Local Honda service representative confirmed seeing this issue regularly on this model year.
Fuel system injector failure
Fuel injector premature failure causing all dashboard warning lights (including check engine and emissions system problem), gas smell, stalling, and power loss. Owner cites Honda Service Bulletins and Manufacturer Communication for same failures on 2017–2019 models and MC-10201454 requesting failed injectors from 2021 models for investigation.
When: Approximately 42,000 miles or more
Symptoms owners cite: All warning lights illuminated; Check engine light; Emissions system problem light; Gas smell; Vehicle stalling; Power loss
Codes mentioned: P0172, P219F
Repairs/costs cited: Owner paid over $2,000 out of pocket for repairs after Honda refused warranty extension.
Recalls/TSBs owners mention: Honda Service Bulletins NHTDA ID 10220352, 10208090, and 22-002 issued for same part failure on 2017–2019 models. Manufacturer Communication MC-10201454 requested failed injectors from 2021 models. Honda opened goodwill case #16219868 but offered only $125 assistance after two weeks, declining warranty extension despite known defect.
CVT transmission housing leak and fluid loss
CVT transmission housing leak causing transmission sluggishness and power loss. Owner expresses concern about potential overheat and transmission failure if leak worsens.
When: Occurred before 60,000 miles (manufacturer warranty expiration)
Symptoms owners cite: CVT housing leak; Transmission sluggishness; Power loss; Gasoline smell (possibly fuel contamination)
Repairs/costs cited: Shop inspection confirmed leak; specific repair cost not stated by owner.
Unexplained engine power loss while driving
Check engine light appears and engine loses all power while driving at highway speed or normal speeds. Power restored only after pulling over, shutting off, and restarting vehicle. Occurs repeatedly over months but dealer cannot reproduce and finds no stored codes.
When: Multiple incidents: August 2025, October 2025, April 2026; approximately 16,500+ miles
Symptoms owners cite: Check engine light; Complete loss of engine power; Vehicle must be pulled to shoulder; Power loss at highway speed; Recurrent issue unable to diagnose
Repairs/costs cited: Dealer diagnostic found no issues and could not reproduce failure.
Recalls/TSBs owners mention: Manufacturer opened a case and encouraged owner to call again if failure recurred; no assistance provided.
Rear differential crack
Rear differential cracked at highway speed with loud noise. No external undercarriage damage evident. Honda claims driver caused damage by reversing and striking object hard, but owner notes absence of any other damage and suspects defective rear seal based on research.
When: Occurred at highway speed (60 mph); vehicle has extended warranty
Symptoms owners cite: Loud boom from rear; Cracked rear differential; No other visible undercarriage damage
Repairs/costs cited: Owner states extended warranty exists but Honda appears unwilling to cover under warranty.
Recalls/TSBs owners mention: Honda attributed failure to owner driving in reverse and hitting object; owner disputes explanation and claims defective rear seal is root cause.
Unexplained highway speed loss
Vehicle speed unexpectedly decreases from 60 mph to 30 mph while highway driving. Occurs multiple times over three months. Only remedy is to pull over and shut off vehicle to reset.
When: Four incidents in three-month period
Symptoms owners cite: Unintended speed reduction from 60 mph to 30 mph; Recurrent issue; Requires shutdown and restart
Inadvertent reverse engagement and brake failure
While driving slowly (5 mph) into garage, vehicle shifted into reverse against driver input. Instrument cluster lights went blank. Brake pedal did not respond to pressure and vehicle continued moving, rolling over rocks. Only stopped after parking brake engaged. Dealer unable to reproduce or diagnose.
When: Approximately 14,800 miles; vehicle is disabled-accessible modified
Symptoms owners cite: Gear shifter stuck in park (initially); Inadvertent reverse engagement; Instrument cluster blackout; Brake pedal unresponsive; Vehicle does not stop despite brake application
Repairs/costs cited: Dealer diagnosed detached interior roof harness cable behind rearview mirror (caused by owner's repeated placement of handicap placard). Repair performed at owner expense.
Recalls/TSBs owners mention: Manufacturer refused warranty coverage. Referred owner to NHTSA for assistance.
Electric power steering (EPS) gearbox stiction
Steering wheel becomes stuck during turning, requiring additional force to complete or exit turn. Symptoms worsen progressively over time and are more pronounced in sharper turns, creating risk of overcorrection or inability to straighten wheel.
When: First noticed May 2024 (vehicle purchased August 2021); 42,000 miles at time of complaint
Symptoms owners cite: Steering wheel stiction during turns; Requires additional force to exit turn; Unpredictable sticking; Worsening over time; More severe in sharper turns
Repairs/costs cited: Honda service technician recommended EPS gearbox assembly replacement; estimated cost approximately $4,000.
Recalls/TSBs owners mention: Honda service center initially placed repair responsibility on customer, citing that vehicle is at/beyond 36,000-mile warranty threshold (42,000 miles present at complaint). Case remains unsettled with no repair authorization granted.
Oil level rise and gasoline contamination
Oil level on dipstick rose above the upper mark with gasoline odor present, vehicle sitting stationary and cold for hours on level ground. Suggests fuel system or piston leakage into oil sump.
When: <UNKNOWN>
Symptoms owners cite: Elevated oil level above dipstick upper mark; Gasoline smell in oil
