10 FAQs for Buyers

1. Is the Eclipse Cross reliable?

Reliability is below average compared to competitors. J.D. Power ratings are mediocre (2.5-3/5), with CVT and turbo issues being the main concerns. However, if maintained properly and issues are addressed early, it can be reasonably reliable.

2. Should I buy FWD or AWD?

AWD is recommended if you live in areas with snow/winter weather. Mitsubishi’s S-AWC system is quite capable. FWD is adequate for mild climates and offers slightly better fuel economy, but the difference is minimal (same EPA ratings).

3. What’s the fuel economy like in real-world driving?

Expect 23-25 mpg combined in real-world conditions. Highway driving can achieve 27-28 mpg, while city driving drops to 21-23 mpg. The turbo engine requires premium fuel for best performance, though regular is acceptable.

4. How does it compare to the Honda HR-V?

The Eclipse Cross has more power and better driving dynamics, but the HR-V is more reliable, has better cargo versatility, and holds value better. Choose Eclipse Cross for performance, HR-V for practicality and reliability.

5. What year is best to buy?

2019-2020 models are the sweet spot. Early 2018 models had more issues, while 2019+ received software updates and minor improvements. 2021 is identical to 2020. Avoid early 2018 production.

6. Is the CVT transmission reliable?

The CVT has mixed reliability. Regular fluid changes every 60,000 miles (or 30,000 for severe service) are critical. Many issues can be resolved with software updates. Extended warranty coverage is highly recommended.

7. What’s the resale value like?

Poor compared to competitors. Mitsubishi vehicles depreciate faster than Honda, Toyota, or Subaru. Expect to lose 50-60% of value in 5 years vs. 40-45% for Honda/Toyota.

8. Are parts expensive?

Parts are moderately priced, cheaper than European brands but more expensive than Honda/Toyota for some components. Availability can be an issue in some areas. Labor costs are standard.

9. What warranty coverage does it have?

• Basic: 5 years/60,000 miles
• Powertrain: 10 years/100,000 miles
• Roadside Assistance: 5 years/unlimited miles
• Anti-perforation: 7 years/100,000 miles

This is one of the best warranties in the industry.

10. Should I buy new or used?

Used (2019-2020) offers better value due to heavy depreciation. Let the first owner take the depreciation hit. Look for certified pre-owned with remaining warranty. New makes sense only with significant dealer incentives.

Final Buyer Recommendations

✅ BUY IF:

• You prioritize warranty coverage (10yr/100k powertrain)
• You want sporty styling and decent performance on a budget
• You need AWD capability at a lower price point
• You can handle average reliability and higher maintenance costs
• You plan to keep the vehicle within warranty period
• You don’t drive high annual mileage

❌ AVOID IF:

• Reliability and low maintenance costs are top priorities
• You need maximum cargo space
• You plan to keep the vehicle beyond 100,000 miles
• Resale value matters to you
• You want the latest tech features
• You drive primarily in city traffic (CVT stress)

🔍 PRE-PURCHASE INSPECTION CHECKLIST:

For Used Eclipse Cross:

1. ✓ CVT transmission test drive (feel for shuddering at 15-25 mph)
2. ✓ Check oil consumption history (ask for service records)
3. ✓ Inspect for recalls completion (VIN check at dealer)
4. ✓ Listen for turbo whine or unusual engine noises
5. ✓ Test all infotainment functions (freezing issues)
6. ✓ Check for rear differential noise on AWD models
7. ✓ Inspect brake rotors for warping
8. ✓ Verify remaining warranty coverage
9. ✓ Review CarFax for accident/flood damage
10. ✓ Professional pre-purchase inspection ($150-$200 well spent)

💰 PRICING GUIDANCE (2024 Used Market):

Negotiation tip: Use known issues (CVT, turbo) as leverage for $500-$1,000 off asking price.

🛡️ RECOMMENDED EXTENDED WARRANTY:

Given reliability concerns, consider:

• Mitsubishi Extra Care: extends coverage to 7yr/100k or 10yr/100k
• Third-party (Endurance, CARCHEX): Compare rates, ensure CVT/turbo coverage
• Cost: $1,500-$3,000 depending on coverage level
• ROI: Likely worthwhile given CVT and turbo failure costs

🏆 Our Final Verdict

The 2018-2021 Mitsubishi Eclipse Cross is a budget-friendly choice with bold styling and excellent warranty coverage, but it lags behind competitors in reliability, technology, and resale value. It’s best suited for buyers who prioritize affordability, want AWD capability, and plan to keep the vehicle within the generous warranty period.

Better alternatives exist (Honda HR-V, Mazda CX-30, Subaru Crosstrek) if you can stretch the budget. However, if you find a well-maintained 2019-2020 model with low mileage at the right price, and you’re comfortable with the known issues, it can serve you well—just budget for maintenance and consider extended warranty coverage.
