2002 NISSAN MAXIMA

Typical onset: 80,000-130,000 mi

Symptoms: Grinding or shuddering between 2nd-3rd gear shifts, Slipping under acceleration, especially when warm, Delayed engagement into Drive or Reverse, Burnt transmission fluid smell, dark fluid with metallic particles

Fix: The Jatco RE5F22A 5-speed auto is notoriously weak behind the VQ35DE. Clutch pack material sheds, clogs valve body and oil cooler. Rebuild requires 8-12 hours labor, but most shops recommend replacement with remanufactured unit due to high re-failure rate. External cooler addition is mandatory during repair. Used units fail quickly.

Estimated cost: $2,800-4,500

Typical onset: 90,000-150,000 mi

Symptoms: Rattling from exhaust manifold area on cold start, Sudden loss of power and Check Engine Light, Metallic grinding noise from engine bay, Catastrophic engine failure: scored cylinder walls, damaged pistons, spun bearings

Fix: Pre-cats integrated into exhaust manifolds break apart; ceramic substrate gets sucked into cylinders. Once ingested, requires complete engine rebuild or replacement: all pistons, rings, honing/boring cylinders, crank polishing, bearings. 25-35 hours labor for proper rebuild. Short block replacement is 18-22 hours. This explains the frequent engine rebuild jobs in the data.

Estimated cost: $4,500-7,500

Typical onset: 70,000-110,000 mi

Symptoms: Clunking from front suspension over bumps, Wandering or loose steering feel, Uneven tire wear on inside edges, Excessive play detectable during tire shake test

Fix: Ball joints are pressed into control arms and fail from wear. Nissan sells only complete control arm assemblies (non-serviceable design). Replace both sides simultaneously. 2.5-3.5 hours labor for both sides, includes alignment. This matches the NHTSA recall component for lower control arms.

Estimated cost: $600-950

Typical onset: 60,000-100,000 mi

Symptoms: Excessive vibration at idle, especially in Drive with brake applied, Clunk when shifting from Park to Drive/Reverse, Engine rocks noticeably during acceleration or deceleration, Visible sagging of engine/transmission when inspected

Fix: Hydraulic mounts deteriorate, leak fluid, and collapse. Transmission mount (rear) fails most frequently. Replace all three mounts (front, rear trans mount, torque strut) together. 3-4 hours labor total. Matches frequently-documented transmission mount repairs in data.

Estimated cost: $450-750

Typical onset: 80,000-140,000 mi

Symptoms: Rough idle and hesitation during acceleration, Check Engine Light with P0171/P0174 lean codes, Poor fuel economy, 3-5 mpg drop, Stalling at stops after highway driving

Fix: Hot-wire MAF sensor gets contaminated from oil residue (often from over-oiled aftermarket air filters). Clean with MAF-specific cleaner first (0.3 hours). If cleaning fails, replacement needed (0.8 hours). Use OEM sensor only; aftermarket units cause recurring issues.

Estimated cost: $150-400

Typical onset: 100,000-160,000 mi

Symptoms: Fuel gauge reads empty when tank is full, or bounces erratically, Gauge sticks at one position regardless of fuel level, Inaccurate range-to-empty calculations

Fix: Resistor strip in fuel tank sending unit wears out. Requires fuel tank drop and pump/sender module replacement. 2.5-3 hours labor. Matches fuel filter documentation (accessed during tank drop). Dealer-only part in many cases.

Estimated cost: $400-650
