Get the original OEM Wiring Diagram Manual for the 2018-2022 Honda HR-V, available in a convenient PDF format.
The 2018–2022 Honda HR-V is a subcompact crossover positioned below the CR-V, built on a light, efficient platform with front-wheel drive standard and optional all-wheel drive. Power comes from a naturally aspirated 1.8L inline-four paired to a CVT (or a 6-speed manual in limited trims/years). Owners value practicality, visibility, and efficiency; complaints center on CVT behavior, modest power, and aging infotainment electronics.

Top Competitors
Top 10 Recalls, Advisories & TSB Highlights for 2018–2022 Honda HR-V
1. Fuel Pump Recall (NHTSA 20V-134, 21V-004) Affects 2018-2020 models. The low-pressure fuel pump may fail, causing the engine to stall without warning while driving. This is a serious safety concern. Honda replaced affected fuel pumps free of charge. Check if your VIN has been serviced, as this was a widespread issue affecting multiple Honda models.
2. Airbag Inflator Recall – Takata (Multiple Recalls) Certain 2018-2019 models may have defective Takata airbag inflators that can rupture and spray metal fragments. This ongoing recall affects millions of vehicles across brands. Critical safety issue—verify replacement has been completed before purchasing any used HR-V from this era.
3. Brake System Hose Recall (NHTSA 19V-120) Affects some 2018-2019 models. The rear brake hose may have been improperly assembled, potentially causing brake fluid leakage and reduced braking performance. Dealers inspected and replaced faulty hoses. Check service records to confirm completion.
4. Parking Brake Cable Corrosion (TSB 19-078) Models in salt-belt states may experience parking brake cable corrosion, leading to the parking brake not releasing properly or becoming stuck. TSB recommends cable inspection and replacement if corroded. Important for buyers in snowy/salted road regions.
5. Premature Rear Brake Wear (TSB 18-077, Multiple Owner Complaints) Widespread reports of rear brake pads wearing excessively fast, sometimes needing replacement before 20,000 miles. While Honda issued guidance on proper break-in procedures, many owners still experience this issue. Budget for earlier-than-expected rear brake service.
6. AC Compressor Clutch Failure (TSB 20-051) Some 2018-2020 models experience AC compressor clutch failure, resulting in no air conditioning. Honda extended warranty coverage for certain VINs. During test drives, verify AC blows cold consistently. Replacement can cost $1,000+ out of warranty.
7. Infotainment System Freezing/Glitches (Multiple TSBs) The 7-inch Display Audio system may freeze, reboot randomly, or experience touchscreen responsiveness issues. Software updates have been released to address these problems. Test all infotainment functions thoroughly, including Apple CarPlay/Android Auto connectivity.
8. Sunroof Drain Tube Clogging (TSB 19-011) Sunroof-equipped models (EX and above) may have drain tubes that clog with debris, causing water to leak into the cabin, typically at the A-pillars or footwells. Regular cleaning prevents this, but check for water stains or musty odors indicating past leaks.
9. Excessive Road Noise/Wind Noise (Owner Complaints, No Official TSB) Many owners report excessive road noise and wind noise, particularly around the A-pillars and windows at highway speeds. This appears to be a design characteristic rather than a defect. Honda has not issued official remedies, though some dealers have added weatherstripping.
10. CVT Transmission Judder/Shudder (TSB 19-009) Some owners report CVT vibration or shuddering during acceleration, especially from a stop. Honda released a software update to recalibrate transmission control. While not as problematic as CVTs in some other Honda models, be alert for unusual transmission behavior during test drives.
Before Purchasing:
- Run a VIN check at Honda’s recall website (recalls.honda.com) to verify all recalls completed
- Request complete service history showing recall and TSB work
- Budget approximately $500-800 annually for maintenance beyond routine oil changes due to brake wear issues
- Have a pre-purchase inspection focus on brakes, AC function, and listen for transmission abnormalities

FAQs for 2018–2022 Honda HR-V Buyers
Is the HR-V reliable?
Yes, the HR-V has an excellent reliability record. Honda consistently ranks well in reliability surveys, and this generation HR-V experiences fewer problems than many competitors. Expect minimal major issues with proper maintenance.
Which model years are best?
Later years benefit from incremental software updates. A well-maintained 2020–2022 example is often the safest buy.
Is the CVT a problem?
Most issues stem from neglected fluid changes. Regular service significantly reduces risk.
What is the most expensive common repair?
CVT replacement, if needed, is the highest-cost item.
Is AWD worth it?
AWD improves winter traction but adds maintenance (rear differential service).
How long does the engine last?
With proper maintenance, 200,000+ miles is common.
Is it safe to drive with warning lights on?
Brake, airbag, or overheating warnings should be addressed immediately.
What should buyers inspect before purchase?
CVT service records, brake condition, alignment, and recall completion.
Should I get FWD or AWD?
Choose FWD if you mostly drive in mild climates and want better fuel economy (saves about 2-3 mpg). Opt for AWD if you experience snow, ice, or frequently drive on unpaved roads. The AWD system adds capability without a huge fuel penalty.
Which trim level offers the best value?
The EX trim (2019+) offers the sweet spot with Honda Sensing safety features, a sunroof, and the larger touchscreen. The Sport adds styling but minimal functional upgrades. Avoid 2018 models without Honda Sensing if safety tech matters to you.
Is the engine powerful enough?
The 141-hp engine handles city driving well but struggles with highway merging and passing, especially with passengers or cargo. It’s adequate for daily commuting but not for those who prioritize spirited driving or frequently travel on highways with steep grades.
What are common problems to watch for?
Relatively few major issues, but be aware of: premature brake wear (especially rear brakes), occasional AC compressor failures, and infotainment system glitches. Check for proper AC function and listen for brake noise during test drives.
How does cargo space compare to competitors?
The HR-V excels here. The Magic Seat system provides 58.8 cubic feet with seats folded, beating the Mazda CX-30, Nissan Kicks, and Hyundai Kona. The flexible seating configurations allow you to carry tall items or create a nearly flat load floor.
What’s the real-world fuel economy?
Expect 26-28 mpg combined with AWD and 28-31 mpg with FWD in mixed driving. Highway driving can reach 32-34 mpg. The CVT transmission helps maximize efficiency but can feel sluggish during acceleration.
Are there any significant changes between model years?
2019 is a key year: Honda Sensing became standard across all trims, and the Touring trim was added. 2018 models lack standard safety tech on lower trims. 2020-2022 saw only minor updates, making any 2019+ model essentially equivalent.
How much should I expect to pay (used)?
As of early 2025, expect to pay approximately $16,000-$20,000 for 2018-2019 models, $19,000-$23,000 for 2020-2021, and $21,000-$26,000 for 2022 models, depending on mileage, condition, and trim level. AWD models command a $1,000-$2,000 premium.
What are the main competitors, and how does it compare?
Key rivals include the Mazda CX-30 (more upscale, better driving dynamics), Subaru Crosstrek (better AWD, rougher ride), Hyundai Kona (more powerful engine options), and Nissan Kicks (FWD only, cheaper). The HR-V wins on cargo versatility and reliability but lags in power and refinement compared to newer competitors.
Final Verdict
The 2018–2022 Honda HR-V is a sensible, efficient subcompact crossover with a strong reliability record when maintained properly. It is not quick or luxurious, but it delivers low running costs, practical space, and solid resale value. Buyers who prioritize efficiency and dependability over performance will find it a smart long-term choice.
