2009 NISSAN MAXIMA

Typical onset: 80,000-130,000 mi

Symptoms: shuddering or jerking during acceleration, whining or grinding noise, hesitation when shifting from park to drive, transmission overheating warnings, loss of power or limp mode

Fix: CVT replacement or rebuild required. Factory reman units are 12-16 hours labor plus $3,000-4,000 for the unit itself. Cooler lines and fluid flush are mandatory during replacement. Many shops won't touch CVT rebuilds—replacement is the standard fix.

Estimated cost: $4,500-6,500

Typical onset: 70,000-150,000 mi

Symptoms: burning 1+ quart every 1,000-1,500 miles, blue smoke from exhaust on cold start or acceleration, fouled spark plugs, low oil pressure warning if neglected

Fix: Piston ring wear and cylinder glazing are the root cause. Short-term: frequent top-offs and plug replacements. Long-term requires engine rebuild (new rings, hone cylinders, valve seals) at 25-35 hours labor, or short block replacement at 18-24 hours. Many owners just top off oil every tankful and live with it until engine failure.

Estimated cost: $3,500-6,000

Typical onset: 60,000-100,000 mi

Symptoms: milky or pink transmission fluid, coolant level dropping without visible leaks, transmission slipping or erratic shifting, sweet smell from exhaust

Fix: The internal cooler in the radiator can fail, allowing coolant into CVT fluid (or vice versa). This cross-contamination kills the CVT within days if not caught. Requires radiator replacement, CVT fluid flush (sometimes full CVT replacement if contamination was severe), and coolant system flush. Total 6-10 hours labor depending on whether CVT survived.

Estimated cost: $1,200-5,000

Typical onset: 80,000-140,000 mi

Symptoms: intermittent no-start condition, sudden stalling while driving, rough idle or hesitation, check engine light with P0335 or P0340 codes

Fix: Sensor itself is cheap, but location on back of engine block near flywheel makes it a nightmare. Requires removing starter and sometimes exhaust components for access. 2-4 hours labor depending on tech experience and whether exhaust studs break.

Estimated cost: $300-600

Typical onset: 70,000-110,000 mi

Symptoms: clunking when shifting into drive or reverse, excessive engine movement visible from driver seat, vibration at idle, harsh engagement during acceleration

Fix: Hydraulic mounts wear out and leak fluid. Front mount is straightforward (1.5 hours), but rear transmission mount requires lifting drivetrain (3-4 hours). Most shops replace both at once if one is bad—labor overlap saves time.

Estimated cost: $400-900

Typical onset: 120,000-180,000 mi

Symptoms: rattling noise on cold start that disappears after 5-10 seconds, check engine light with variable valve timing codes, rough idle when engine is cold

Fix: VQ35DE uses primary and secondary timing chains with hydraulic tensioners. If oil changes were neglected, tensioners wear and chains slack. Requires front cover removal, new chains, tensioners, and guides. 8-12 hours labor. If caught early (just tensioners), can sometimes get away with 4-6 hours, but most techs recommend full chain kit.

Estimated cost: $1,200-2,200

Typical onset: 80,000-120,000 mi

Symptoms: clunking over bumps, wandering or loose steering feel, uneven tire wear on inside edges, alignment won't hold

Fix: Bushings crack and separate, especially in rust-belt states. Nissan sells arms with bushings pre-installed (no press required). 2-3 hours for both sides plus alignment. Aftermarket arms are cheaper but quality varies.

Estimated cost: $500-800
