Quick numbers, 2026:
2.5L Altima at an independent shop: $250 to $425 installed. 3.5L V6: $390 to $620 due to intake plenum R and R. Nissan dealer adds 30 to 40 percent. DIY 2.5L: $115 to $210 in parts, 75 to 90 minutes. CVT inhibitor switch failure can present as a no-crank, rule it out before starter spend.
Altima engine choice drives the cost split
The Altima has been offered with four meaningfully different engines over the past two decades: the 2.5L QR25DE 4-cylinder (2002 to 2018), the 2.5L PR25DD 4-cylinder (2019 to 2026), the 3.5L VQ35DE V6 (2002 to 2020), and the 2.0L VC-Turbo variable-compression 4-cylinder (2019 to 2024). The 4-cylinder engines place the starter on the front of the engine block bolted to the bell housing in a position any independent shop can access from underneath in 30 to 45 minutes.
The 3.5L VQ35DE is a different proposition. The starter sits on top of the engine in the valley between the cylinder banks, directly under the upper intake plenum. Nissan's service procedure calls for throttle body removal, upper plenum removal, EGR connection disconnection (on years equipped), and routing of multiple wiring harness retainers. Published flat-rate time is 2.4 hours, which translates to a labor bill roughly twice that of the 4-cylinder job. The starter unit itself is only $30 to $35 more expensive at the parts counter; almost all of the cost difference is labor.
For Altima buyers comparing the 4-cylinder and V6 trims on the used market, the starter job alone is roughly a $200 to $250 swing in lifetime ownership cost. Combined with the V6's higher fuel consumption and oil change costs, the 4-cylinder is the more economical long-term choice for most buyers unless the V6's performance is genuinely needed.

Hitachi is the OEM, and the aftermarket is well-stocked
Nissan has used Hitachi as its primary starter supplier since the early 2000s. The Hitachi unit on the 2.5L QR25DE is one of the most commonly stocked starters at any North American parts counter, with at least three reman SKUs available at any given AutoZone or O'Reilly. The chain stores carry Duralast Gold and Master Pro branded reman starters that meet OE specifications, plus Cardone and BBB Industries units. All are functionally equivalent for the average Altima owner.
For the 3.5L VQ35DE, the OEM Hitachi unit is also widely stocked but in fewer SKU options. The VQ35DE is shared with the 350Z, 370Z, Maxima, Pathfinder, Infiniti G35 / G37, and several other Nissan products, so aftermarket production volume justifies multiple reman options. The Cardone unit (part 6664N) is the most common chain-store option at roughly $145 to $215 retail.
A common mistake: assuming an Infiniti G37 starter will fit an Altima 3.5. The motor unit is identical but the mounting bracket and harness connector differ. Match by exact vehicle and year using the AutoZone or O'Reilly catalog tools before purchase. Nissan Parts Deal's VIN lookup at nissanpartsdeal.com is the definitive cross-reference for OEM-fit confirmation.
CVT inhibitor switch: the Altima no-crank trap
Every Altima sold since 2007 uses a Jatco CVT, and every CVT has an inhibitor switch that prevents engine cranking unless the transmission is in Park or Neutral. The Altima's inhibitor switch sits on the side of the transmission case and is exposed to road spray, salt, and grime. After 100,000 to 150,000 miles the internal contacts in the switch can corrode and intermittently fail.
The failure mode looks exactly like a bad starter. Turn the key, nothing happens. Try again in five seconds, the engine cranks normally. Try the next morning, nothing happens for ten attempts. Most owners conclude the starter is failing and pay for a replacement. The starter is fine; the inhibitor switch is the culprit.
A simple field test: with the key in Run (engine not started), shift to Neutral and try cranking. If the engine starts in Neutral but not in Park, the inhibitor switch is failing. The switch is a $45 to $85 part and a 30-minute job at an independent shop. For the full diagnostic procedure see the intermittent no-start cost guide, and for general symptom mapping see the starter symptoms guide.
DIY procedure for the 2.5L Altima
Disconnect the negative battery terminal first, always. Raise the front passenger side of the vehicle and support on a jack stand rated for at least 2,500 pounds. The Altima 2.5L starter is visible immediately on the front of the engine block at the bell housing. Two mounting bolts (14 mm head), one main battery cable terminal (13 mm nut), one solenoid trigger wire (push-on connector).
Remove the trigger wire first, then the battery cable nut and cable, then the two mounting bolts. The starter will drop into your hand. Slide it out from underneath. Installation reverses the procedure. Torque the mounting bolts to Nissan specification (33 lb-ft on the QR25DE and PR25DD). Torque the battery cable nut to 8 lb-ft. Reconnect the negative battery and start the engine. The first crank should be noticeably crisper.
A specific Altima DIY tip: the upper starter bolt on the QR25DE engine is partially blocked by an A/C compressor bracket on some production years. If you cannot reach it with a standard socket and extension, a swivel adapter or a wobble extension makes the difference. AutoZone Loan-A-Tool stocks both at no rental cost with a refundable deposit. See the general DIY guide for more procedure details.
