Infiniti Maintenance Cost by Model and Year: A Complete Breakdown
There’s a certain peace of mind that comes from knowing what you’re getting into financially before you buy a luxury vehicle—and maintenance costs are a huge part of that picture.
Infiniti occupies an interesting middle ground in the luxury world. It’s not as expensive to maintain as a BMW or Mercedes, but it’s not quite as cheap as a Lexus. The reality is that your maintenance costs will vary significantly depending on which model you choose, which year you buy, and how many miles you plan to drive.
Let’s break down the real maintenance costs for Infiniti models by model and year, so you know exactly what to expect.
Infiniti Maintenance Cost Overview
The Big Picture
Over 10 years, the average Infiniti will cost about $11,690 in maintenance and repairs according to CarEdge data . That’s cheaper than BMW ($15,991) and Mercedes ($12,962), but more expensive than Acura ($8,566) and Lexus ($7,130) .
The average annual maintenance cost across all Infiniti models is about $638 per year, according to RepairPal . That means you’re looking at roughly $50-60 per month in maintenance costs once your vehicle is out of warranty.
The first 10 years also carry a 33.22% chance of a major repair. That means about one in three Infiniti owners will face a significant repair bill during their first decade of ownership .
Infiniti QX60 Maintenance Costs
Best Overall Value
The Infiniti QX60 is one of the most cost-effective luxury SUVs to maintain. Here’s what the data shows:
- Annual maintenance: About $640 per year, compared to $1,127 for similar full-size luxury SUVs
- First 5 years: Approximately $3,740 in maintenance and repairs—nearly $1,800 below the industry average
- First 10 years: Around $11,700 total maintenance costs
- Reliability score: 3.5 out of 5 from RepairPal, ranking 2nd out of 19 full-size luxury SUVs
- Unscheduled repairs: 0.9 visits per year, with only a 10% chance of a severe repair (industry average is 19%)
For the 2026 QX60 specifically: The Luxe trim shows 5-year out-of-pocket costs of $57,710, with maintenance estimated at $7,196 over five years . That’s about $1,439 per year, though this figure includes more than just maintenance (it also factors in fuel, insurance, financing, and state fees).
Common Repair Costs on the QX60

- Throttle body replacement: $1,056-$1,255
- Power window regulator: $323-$387
- Ignition coil replacement: $186-$265
- MAP sensor replacement: $325-$354
- Timing chain tensioner: $2,715-$3,642
Infiniti Q50 Maintenance Costs
Solid Value with Some Caveats
The Infiniti Q50 is the brand’s last sedan standing in the US, and it offers decent maintenance costs—but model year matters significantly.
- Average annual maintenance: About $648, slightly higher than the Infiniti average of $638
- 60,000-mile service: $600-$1,200 depending on the shop
- 10-year maintenance: Slightly above the Infiniti average due to some reliability concerns
2024 Q50 Specific Costs
Edmunds data for the 2024 Q50 reveals some interesting patterns :
| Trim | 5-Year Maintenance Cost |
|---|---|
| Luxe RWD | $6,206 |
| Luxe AWD | $6,364 |
| Sensory RWD | $7,877 |
| Sensory AWD | $8,036 |
| Red Sport 400 RWD | $8,524 |
| Red Sport 400 AWD | $8,734 |
Notice how the higher trims (Sensory and Red Sport 400) carry significantly higher maintenance costs. The Red Sport 400 AWD’s 5-year maintenance is a whopping $8,734—about $2,500 more than the base Luxe RWD .
The biggest jump comes in year 4, where the Red Sport 400 AWD’s maintenance bill hits $3,663 in a single year . This is likely due to major scheduled services like fluid flushes, spark plugs, and belt inspections.
If you’re shopping for a Q50, the 2020 model year is widely considered the sweet spot—fewer complaints, better reliability, and lower maintenance costs than earlier or later years .
Infiniti QX80 Maintenance Costs
The Big SUV, Bigger Costs
The Infiniti QX80 is the brand’s flagship full-size SUV, and its maintenance costs reflect its size and complexity.
- Annual maintenance: About $907 according to Kelley Blue Book
- 5-year maintenance: Approximately $4,539
- Total 5-year out-of-pocket expenses: $65,976 (including fuel, insurance, financing, and state fees)
For the 2025 QX80 Luxe, the 5-year maintenance estimate is $3,198, with an additional $712 in repairs . That’s actually lower than some estimates because it’s a brand-new model with fewer wear-and-tear items expected in the first five years.
The QX80’s maintenance costs are higher than the QX60, but that’s expected for a larger, more complex vehicle. The 8,500-pound towing capacity and heavy-duty components mean more wear on parts like brakes and suspension.
Infiniti Q60 Maintenance Costs
The Sporty Coupe’s Cost Picture
The Infiniti Q60 is a performance coupe that’s more affordable to maintain than you might think.
- 10-year maintenance: Approximately $9,183—$5,136 below the luxury coupe industry average
- First 5 years: About $2,960 in maintenance and repairs
- Major repair chance: 25.13% over 10 years, which is 11.50% better than similar vehicles
| Year | Annual Maintenance Cost | Major Repair Probability |
|---|---|---|
| 1 | $392 | 2.59% |
| 2 | $455 | 4.30% |
| 3 | $554 | 4.82% |
| 4 | $713 | 8.52% |
| 5 | $845 | 12.21% |
| 6 | $1,052 | 13.73% |
| 7 | $1,212 | 14.81% |
| 8 | $1,274 | 19.15% |
| 9 | $1,315 | 21.16% |
| 10 | $1,371 | 25.13% |
The Q60’s maintenance costs are lower than the Q50’s because it shares many components but is less common—fewer owners means fewer data points, but the trend shows it’s a relatively affordable coupe to maintain .
Infiniti QX55 Maintenance Costs
The Newcomer
The Infiniti QX55 is a relatively recent addition to the lineup, so long-term data is limited. Here’s what we know from Edmunds data on the 2025 model:
- 5-year maintenance: Approximately $4,602
- 5-year repair cost: $1,138 (estimated)
- Total 5-year out-of-pocket: $67,080-$73,883 depending on trim
The QX55 uses a CVT transmission and a variable compression engine, which are more complex than traditional setups—this could lead to higher repair costs as the vehicle ages .
Maintenance Costs by Model Comparison
| Model | Annual Maintenance Cost | 5-Year Maintenance | 10-Year Maintenance |
|---|---|---|---|
| QX60 | $640 | ~$3,740 | ~$11,700 |
| Q50 (Base) | $648 | ~$6,206 | ~$8,500 (est.) |
| Q50 (Red Sport) | ~$850 | ~$8,524 | ~$11,500 (est.) |

| Industry Average (Luxury) | ~$779 | ~$5,500 | ~$12,000 |
