Owners of 2009 Nissan Altimas report recurring suspension problems across the fleet. Front struts crack, break, or detach during normal driving—one owner experienced detachment at 45 mph. Coil springs fracture at low mileage (35,600 miles in one report) and again at higher mileage (115,000 miles), sometimes on both front and rear sides. Control arms and steering knuckles fail, occasionally totaling the vehicle.
Abnormal noises dominate complaints: clanking, grinding, and knocking from the front end, especially under braking or when accelerating. Vibration and shaking at freeway speeds is widespread, with owners describing the vehicle as sliding or feeling unstable. Strut insulators creak loudly even on new vehicles.
Nissan issued recall campaign 09V358000 for struts built out of specification, but owners report their VINs were excluded from coverage despite displaying identical symptoms. Dealers and independent shops struggle to diagnose the root cause, offering vague findings. Repair costs are steep—$1,020 for front strut replacement in one documented case, with additional wheel, knuckle, and control arm replacement pushing repair bills higher.
Failure modes owners describe
Strut failure and damage
Front and rear struts have cracked, broken, or detached from their mounts. Owners report struts separating during driving, cracks developing in strut bodies, and insulator components failing. Multiple narratives reference broken strut housings and detachment events.
When: Between 80,700 and 184,000 miles, though one report at 95,000 miles involved detachment
Symptoms owners cite: loud clanking or grinding noise from front end; knocking in wheel area; abnormal grinding when braking; vehicle shaking or vibrating; rough ride quality
Repairs/costs cited: Front strut modular assembly and right front strut replacement cost $1,020.26 in one case; dealers sometimes recommend strut replacement along with bearings and CV boots
Recalls/TSBs owners mention: NHTSA Campaign 09V358000 (Suspension) issued for struts built out of spec; some owners' VINs were not included in recall despite exhibiting same symptoms
Coil spring fracture
Front and rear coil springs fracture or fail without obvious impact. Owner reports include spontaneous spring cracks discovered during inspection and progressive deterioration of ride quality leading to diagnosis of failed springs.
When: At 35,684 miles in one case; 115,000 miles in another; failure can occur on both driver and passenger sides at different times
Symptoms owners cite: rattling noise from front end without warning; vehicle instability; rough ride
Repairs/costs cited: Repair facilities diagnosed the need for replacement of coil springs on both front and rear axles; one vehicle had additional wheel and control arm damage
Control arm and knuckle failure
Top control arms and steering knuckles experience damage or failure, sometimes in conjunction with wheel and suspension damage after pothole impact.
When: 25,000 miles in reported case
Symptoms owners cite: grinding noise; tire damage after pothole strike
Repairs/costs cited: Dealer diagnosed both top control arms and knuckles requiring replacement, along with passenger side alloy wheel, rear driver side alloy wheel, and engine cradle; insurance totaled vehicle
Strut insulator noise and degradation
Front strut insulator components deteriorate or fail, producing creaking and loud noises. One brand-new vehicle exhibited this issue immediately upon delivery.
When: Can occur early in vehicle life; one complaint on new vehicle
Symptoms owners cite: loud creaking noise from front end; loud noise when driving
Repairs/costs cited: Identified at dealerships; repair costs not specified in narratives
Suspension-related vibration and shake
Vehicles exhibit abnormal vibration, shaking, or sliding sensation particularly at freeway speeds or when turning. Some owners describe the vehicle sliding and feeling shaky at certain speeds; one owner felt shake at 55 mph, another at 45 mph turns.
When: Variable mileage; one noted as occurring suddenly while driving freeway; one at 100,000 miles
Symptoms owners cite: shaking or vibrating at freeway speeds; sliding sensation; rough ride quality; vibration at low speeds (10 mph); front end shake
Codes mentioned: ABS warning light, brake warning light, check engine light, TPMS warning light (in one case with strut housing failure)
Repairs/costs cited: Nissan service centers and independent shops unable to consistently diagnose cause; described as inconclusive findings
Recalls/TSBs owners mention: NHTSA press release explained 2009-2010 Nissan Altima and Maxima struts built out of spec causing this sensation; recall campaign 09V358000 exists but some VINs excluded
