Why does my 2016–2018 Nissan Maxima hesitate or shudder when I pull away?

Short answer: Many Maxima owners feel a hesitation or shudder from a stop. Nissan has bulletins for CVT judder on its V6 models, including the Maxima, that use codes like P17F0 and P17F1 and start with a transmission software update. Have a Nissan dealer check for stored codes and updates.

Symptom: A pause or lag when you press the gas from a stop, a shudder or vibration at low speed, or a feeling that the transmission is slipping.

What to check first

1. Ask a Nissan dealer to check for stored CVT codes such as P17F0 or P17F1. Some of these don't turn on the check-engine light.
2. Ask about CVT software updates and bulletins for your VIN.
3. Check the CVT fluid condition and service history.
4. Check your warranty. Ask the dealer whether any powertrain or extended CVT coverage applies to your VIN.

Likely causes

1. CVT software or control logic. Nissan's first step is often reprogramming.
2. Worn or old CVT fluid. Fluid condition affects judder.
3. Internal CVT wear. If updates don't fix it.

What it usually costs

A software update is often covered if you're in warranty. I couldn't find a reliable price for Maxima CVT repairs, so get a written quote and ask about any Nissan coverage before paying.

Is it safe to keep driving?

A mild hesitation is usually drivable, but it can be risky when pulling into traffic. Leave extra room until it's fixed. If the car loses drive or goes into limp mode, stop and get it checked. Verify with a mechanic.

DIY or shop?

Shop (Nissan dealer) for codes and software. Fluid service needs the correct Nissan fluid and procedure.

Recalls, bulletins and complaints in plain words

• No recall covers Maxima CVT hesitation in NHTSA's list for these years.
• Nissan bulletin NTB15-015g (March 2017, includes 2016–2017 Maxima): covers CVT judder with codes P17F1 or P17F0 stored and gives dealers a repair procedure.
• Nissan bulletin NTB16-085a (March 2017, includes 2016–2017 Maxima): adds software logic that stores the P17F0/P17F1 judder codes to help dealers find the cause. 2018 models aren't listed, so ask the dealer what applies to yours.
• NHTSA complaints: 44 of 284 Maxima complaints from 2016–2018 mention the CVT, transmission, hesitation, judder or shudder.

What owners report

• A Maxima.org owner with a 2016 Maxima described hesitation when starting to move from a stop.
• An r/maxima owner with a 2017 SV posted about a weird feeling from the drivetrain while driving.

My take

My advice as a former finance manager: if you're buying a used Maxima, ask the seller for service records showing CVT updates or fluid service, and think about an extended warranty that covers the CVT.

Vehicle focus: 2016–2018 Nissan Maxima (8th generation) with the CVT.

Safety / mechanic note

Hesitation when pulling into traffic is a safety risk. Verify with a mechanic.
