Infiniti vehicles have an average annual repair cost of $638/year with below-average reliability ratings. The CVT transmission (shared with Nissan) carries the same failure risk as the broader Nissan-Renault CVT platform, and electrical system complexity adds further risk for out-of-warranty Infiniti owners.
The table below shows what common Infiniti mechanical failures cost out of pocket versus what extended warranty covers. One covered repair often exceeds the annual cost of coverage.
| Common Repair | Average US Cost | Covered by Extended Warranty? |
|---|---|---|
| CVT transmission failure | $3,500–$8,000 | ✅ Yes |
| Timing chain / VVT failure | $1,500–$3,500 | ✅ Yes |
| Electrical / control module failure | $800–$2,200 | ✅ Yes |
| Air suspension failure (QX80) | $1,500–$3,500 | ✅ Yes |
| AC compressor failure | $800–$1,800 | ✅ Yes |
| Infotainment / InTouch failure | $700–$2,000 | ✅ Yes |
| Brake pads and rotors | $400–$900 | ❌ No |
| Accident body damage | $900–$6,500 | ❌ No (Car insurance) |
These are two completely separate products covering completely different risks. Most Infiniti owners need both.
| Scenario | Car Insurance | Extended Warranty |
|---|---|---|
| CVT transmission failure (most common Infiniti failure) | ❌ No | ✅ Yes |
| Rear-end collision damages your bumper | ✅ Yes (collision) | ❌ No |
| Engine fails due to internal wear | ❌ No | ✅ Yes |
| Hailstorm dents the hood | ✅ Yes (comprehensive) | ❌ No |
| Transmission fails at 90,000 miles | ❌ No | ✅ Yes |
| AC compressor dies in summer | ❌ No | ✅ Yes |
| Hit by an uninsured driver | ✅ Yes (UM/UIM) | ❌ No |
| Electrical system failure | ❌ No | ✅ Yes |
| Vehicle theft | ✅ Yes (comprehensive) | ❌ No |
| Suspension and drivetrain wear | ❌ No | ✅ Yes |
These are the Infiniti-specific factors to confirm before purchasing any extended warranty plan.
Infiniti QX60 and QX50 CVT transmissions share the same platform as Nissan's problematic CVT units. The failure risk and replacement cost ($3,500 to $8,000) are comparable to Nissan's CVT exposure. Confirm CVT coverage is the top priority when evaluating any Infiniti extended warranty plan.
Infiniti's VQ35DE and VQ37VHR V6 engines have documented timing chain tensioner failures after 100,000 miles. Confirm engine internal coverage specifically includes the timing chain system.
QX80 air suspension failures are an above-average risk for this model. Confirm air suspension coverage for QX80 and other air-suspended Infiniti variants.
Infiniti dealer labor rates run $150 to $200 per hour. Confirm warranty covers labor at these rates, as out-of-pocket gaps at luxury labor rates add up quickly on multi-hour repairs.
Infiniti InTouch dual-screen infotainment systems have above-average failure rates on QX60 and Q50 models after year 5. Electrical system coverage should include infotainment.
Infiniti's factory powertrain warranty is 5 years or 60,000 miles. Given the CVT failure risk (documented as early as 60,000 to 80,000 miles on some QX60 models), pre-expiry coverage is critical.
