🔧 Top 10 Common Mechanical Issues (Root Cause & Fix)

Excessive brake wear / brake judder
🔍 Root Cause: Heavy curb weight overheats pads/rotors; towing worsens heat load.
🛠️ Fix: Install quality ceramic pads + premium rotors; flush brake fluid; confirm caliper slide pins move freely.
Front suspension clunks (control arms / end links)
🔍 Root Cause: Wear in sway bar links, control arm bushings, and ball joints from SUV weight.
🛠️ Fix: Replace worn end links/bushings; inspect ball joints; perform alignment after suspension work.
Rear air-suspension sag (if equipped)
🔍 Root Cause: Aging air bags/leaky lines or weak compressor.🛠️ Fix: Leak-test, replace air springs/lines; replace or rebuild compressor if slow to fill.
Steering vibration / shake at highway speeds
🔍 Root Cause: Tire imbalance, worn tires, or alignment drift; sometimes worn steering components.🛠️ Fix: Road-force balance; rotate/replace tires; alignment; inspect tie rods and steering rack bushings.
Engine oil leaks (valve cover / front timing cover area)
🔍 Root Cause: Gasket hardening from heat cycles.🛠️ Fix: Replace valve cover gaskets and seals; clean PCV system; verify no excessive crankcase pressure.
Rough idle / hesitation
🔍 Root Cause: Dirty throttle body, carbon buildup, worn spark plugs, or weak ignition coils.🛠️ Fix: Throttle body clean + relearn; replace plugs at interval; replace coils if misfire data indicates.
Cooling system weakness (overheating under load)
🔍 Root Cause: Aging radiator, thermostat, or fan clutch/electric fan performance.🛠️ Fix: Pressure test; replace thermostat; service radiator; confirm fan operation; flush coolant on schedule.
Driveline clunk (U-joints / driveshaft)
🔍 Root Cause: Wear in U-joints or slip yoke; towing accelerates wear.🛠️ Fix: Inspect/replace U-joints; lubricate/replace slip yoke; check differential mounts.
4WD engagement issues (4WD models)
🔍 Root Cause: Transfer case actuator/switch issues or low/old transfer case fluid.🛠️ Fix: Scan for 4WD codes; service transfer case fluid; check actuator wiring and vacuum/solenoids if applicable.
Exhaust manifold tick
🔍 Root Cause: Exhaust gasket leaks or cracked manifold from heat cycling.🛠️ Fix: Inspect for soot trails; replace manifold gaskets or manifolds; verify fastener torque.

💡 Top 10 Common Electrical Issues (Root Cause & Fix)

Battery drain / no-start after sitting
🔍 Root Cause: Parasitic draw (modules not sleeping), aged battery, or accessory drain.🛠️ Fix: Parasitic draw test; update/replace offending module; fit AGM battery; clean terminals/grounds.
Infotainment / navigation freezing or rebooting
🔍 Root Cause: Head unit firmware instability or failing internal storage.🛠️ Fix: Software update; hard reset; replace head unit if persistent with confirmed power/ground integrity.
Backup camera intermittent
🔍 Root Cause: Water intrusion at camera or harness fatigue at tailgate.🛠️ Fix: Replace camera; repair tailgate harness; reseal connectors.
Power liftgate slow or won’t open
🔍 Root Cause: Weak struts, latch sensor faults, or module calibration.🛠️ Fix: Replace liftgate struts; adjust latch; recalibrate; diagnose liftgate module.
Power window / door lock actuator failures
🔍 Root Cause: Motor/actuator wear; moisture ingress.🛠️ Fix: Replace failed actuators; verify door harness integrity; lubricate window tracks.

The FX replaced the QX4 as Infiniti’s mid-size SUV. It shares the same FM platform as the rear-wheel drive Nissan 370Z, and it “made no claims of climbing mountains.” Rather, its aggressive shape promised style and quick handling. The similarly sized Nissan Murano is based on the same D platform as the front-wheel drive Nissan Altima. The FX does not have a Nissan-branded equivalent and is not sold in Japan.

The FX introduced its second generation for the 2009 model year as the FX35 and FX50.

Common Issues Reported By Owners

The 2012 Infiniti M Series, which includes the M37, M56, and the M35h hybrid, is a luxury sedan known for its strong performance, luxurious interior, and advanced features. However, like any vehicle, it has some common issues reported by owners. Here’s a detailed look at potential problems:

Common Issues with the 2012 Infiniti M Series

1. Excessive Oil Consumption (M56 with V8 Engine)

Issue: The 5.6L V8 engine in the M56 is prone to consuming oil at higher-than-expected rates.
Symptoms: Frequent need to top off oil, oil warning light, or low oil levels between oil changes.
Solution: Regularly monitor and top off oil levels. Persistent issues may require replacing piston rings or valve seals.

2. Transmission Problems

Issue: The 7-speed automatic transmission may experience rough or delayed shifting, particularly in higher-mileage vehicles.
Symptoms: Jerky gear changes, hesitation when accelerating, or slipping between gears.
Solution: Perform a transmission fluid flush and software update. In severe cases, a transmission rebuild or replacement may be required.

3. Suspension and Steering Concerns

Issue: Suspension components, such as control arms, bushings, and struts, are prone to wear, leading to noises or handling issues.
Symptoms: Clunking or squeaking noises over bumps, uneven tire wear, or loose steering feel.
Solution: Replace worn suspension parts and ensure proper alignment for improved ride quality and handling.

4. Brake Rotor and Pad Wear

Issue: The M Series may experience faster-than-average wear of brake pads and rotors, particularly with aggressive driving.
Symptoms: Squealing or grinding noises during braking, vibration, or reduced braking performance.
Solution: Replace brake pads and rotors as needed, using high-quality components.

5. Infotainment System Malfunctions

Issue: Problems with the infotainment system, including unresponsive controls, freezing screens, and issues with Bluetooth or navigation.
Symptoms: Unresponsive touchscreen, inability to connect devices, or loss of navigation functionality.
Solution: Update the infotainment software or replace faulty system components.

6. Fuel System Issues (M35h Hybrid)

Issue: Hybrid models may experience fuel system problems, including difficulty starting or reduced hybrid system performance.
Symptoms: Engine hesitation, warning lights for the hybrid system, or decreased fuel economy.
Solution: Inspect and repair or replace components such as the fuel pump, sensors, or hybrid battery system.

7. Interior Material Wear

Issue: Premature wear of leather seats, steering wheel, and trim pieces is a common complaint, especially in vehicles exposed to harsh conditions.
Symptoms: Cracking, peeling, or fading of interior materials.
Solution: Regularly condition leather surfaces and protect them from sun exposure. Damaged materials may require repair or replacement.

8. Cooling System Leaks

Issue: The radiator, hoses, and water pump are prone to developing leaks, leading to overheating if not addressed.
Symptoms: Low coolant levels, visible leaks, or engine overheating.
Solution: Inspect and replace faulty cooling system components. Perform regular coolant flushes to maintain system integrity.

9. Headlight Moisture or Fogging

Issue: Moisture can accumulate in the headlight assemblies, affecting visibility and bulb longevity.
Symptoms: Foggy or dim headlights or water droplets visible inside the housing.
Solution: Reseal or replace headlight assemblies. Minor fogging may be resolved with silica gel packs.

10. Hybrid Battery Degradation (M35h Hybrid)

Issue: Hybrid models may experience reduced battery performance or capacity over time.
Symptoms: Decreased hybrid assist, warning lights, or reduced fuel economy.
Solution: Inspect and replace the hybrid battery pack if necessary. Infiniti offers battery warranties for hybrid systems, so check for coverage.

Maintenance Tips for the 2012 Infiniti M Series

Oil Changes: Use high-quality synthetic oil and follow the manufacturer-recommended intervals.
Transmission Service: Regularly flush and refill the transmission fluid to avoid shifting issues.
Tire Care: Rotate tires regularly and maintain proper alignment to prevent uneven wear.
Brake Inspections: Check pads and rotors periodically to ensure optimal performance.
Cooling System Maintenance: Flush the coolant every 30,000–50,000 miles or as recommended in the owner’s manual.
Software Updates: Keep the infotainment and hybrid system software up to date.

Summary

The 2012 Infiniti M Series offers a luxurious and sporty driving experience, with models tailored to different needs—whether you prefer the V6 (M37), the powerful V8 (M56), or the fuel-efficient hybrid (M35h). While it is generally reliable, the vehicle does have some known issues, such as oil consumption in the V8, transmission concerns, and suspension wear. Regular maintenance and addressing problems early can help keep your Infiniti M running smoothly.

If you’re considering purchasing a used model, a pre-purchase inspection and review of the service history are highly recommended.
