When you're shopping for a used mid-size sedan, the 2017 Nissan Altima often pops up on classified sites due to its attractive pricing and comfortable cabin. Yet, buyers frequently wonder whether this model year holds up over time or turns into a mechanical headache. Let's look at the facts. The 2017 Nissan Altima earns a mixed reliability score, weighed down heavily by well-documented issues with its continuously variable transmission, while earning praise for highway fuel economy and seat comfort.
If you're considering buying one or trying to understand your own car's quirks, you need a realistic breakdown of what breaks, what works, and how owner experiences stack up after years on the road.
Mechanical Realities: Engine and Transmission Performance
Under the hood, the 2017 Altima came with two engine choices: a standard 2.5-liter four-cylinder engine making 179 horsepower and a punchy 3.5-liter V6 pushing 270 horsepower. Both paired exclusively with Nissan's Xtronic continuously variable transmission (CVT).
While the four-cylinder engine offers adequate power for daily commuting and stellar highway efficiency, the transmission paired to it remains the car's most scrutinized component.
CVT Troubles and Symptoms
Nissan's CVT units from this era received widespread complaints regarding shuddering, sudden hesitation during acceleration, and premature mechanical failure. Unlike traditional stepped automatic transmissions, CVTs use a steel belt and pulley system. When these components wear prematurely, drivers notice several distinct warning signs:
- RPM surging: Engine revs spike without a corresponding increase in vehicle speed.
- Whining noises: A high-pitched drone or buzzing sound coming from the transmission housing, especially at highway speeds.
- Limp mode: The car refuses to accelerate past a low speed due to a stored transmission error code.
According to data compiled by platforms like CarComplaints, transmission issues make up a significant portion of official grievances for this model year. If you're test-driving a used 2017 Altima, pay close attention to how smoothly the car transitions from a dead stop and whether it hesitates when you press the throttle.
Engine and Electrical Quirks
Beyond the transmission, the four-cylinder engine is generally durable if maintained with regular oil changes, but it's not entirely immune to trouble. Some owners report minor oil leaks around the valve cover gaskets and occasional failures of mass airflow sensors or ignition coils.
On the electrical side, complaints often target the infotainment system. The base screen can freeze, Bluetooth pairing drops randomly, and the rearview camera display sometimes flickers or goes blank due to faulty software logic or loose wiring harness connections behind the dash.
Cabin Comfort and Interior Design
Where the Altima redeems itself for many owners is interior packaging. Nissan spent considerable engineering effort on what they call "Zero Gravity" seats, designed to reduce fatigue on long drives.
Owners consistently rate seat comfort as one of the vehicle's strongest selling points. Whether you're driving across town or embarking on a multi-state road trip, the front seats offer support that rivals cars in higher price brackets.

| 2017 Nissan Altima Cabin Pros |
+-------------------------------------------------+
| * Exceptional front seat ergonomics |
| * Ample rear legroom for adult passengers |
| * Large 15.4 cubic foot trunk capacity |
| * Straightforward physical climate controls |
+-------------------------------------------------+
The rear seat provides generous legroom, and the trunk offers 15.4 cubic feet of cargo space, beating several class rivals in sheer hauling capability for luggage or groceries.
Real-World Owner Satisfaction
Looking at aggregated reviews from platforms like Edmunds, owner sentiment splits into two distinct camps.
Drivers who bought their cars new, adhered strictly to fluid change intervals, and experienced zero mechanical hiccups rate the car between four and five stars. They love the fuel economy—which easily hits close to 38 miles per gallon on the highway—and the supple ride quality over broken pavement.
Conversely, owners who hit transmission failure outside of powertrain warranty coverage leave one-star reviews warning others to stay away. Replacing a CVT out of pocket often costs between 3,500 and 5,000 dollars, which can easily eclipse the resale value of a high-mileage 2017 model.
Common Mistakes to Avoid When Buying
If you've decided a 2017 Altima fits your budget, avoid these common traps during the purchase process:
- Skipping the pre-purchase inspection: Never buy a used Nissan without having an independent mechanic inspect the transmission fluid condition and read the computer for pending trouble codes.
- Ignoring service history: CVT longevity depends entirely on whether the fluid was changed every 30,000 to 40,000 miles. If there's no service record, walk away.
- Buying sight unseen: Always test drive the car up to highway speeds to check for transmission whine and steering wheel vibrations.
For official safety ratings and structural crash test data, you can review the official assessments provided by the NHTSA.
Frequently Asked Questions
Is the 2017 Nissan Altima a reliable car?
It has a below-average reliability record compared to competitors like the Toyota Camry or Honda Accord. While the engine and suspension hold up well, the CVT transmission has a high rate of reported complaints and failures.
How many miles will a 2017 Nissan Altima last?
With diligent maintenance and timely CVT fluid changes, many units cross the 150,000-mile mark. However, neglecting transmission maintenance drastically shortens its lifespan, often leading to failure before 100,000 miles.
Which engine is better in the 2017 Altima?
The 2.5-liter four-cylinder offers better fuel economy and lower maintenance costs. The 3.5-liter V6 provides much faster acceleration and a more engaging drive, but it's harder to find and adds weight over the front wheels.
What should I look for when test driving a used 2017 Altima?
Pay close attention to hesitation when accelerating from a stop, slipping sensations at cruising speeds, and any whining or buzzing noises from beneath the car. Check that all dashboard electronics, infotainment features, and safety sensors function properly.
