Owners describe multiple distinct suspension failures on 2006 Maximas. Front coil springs fracture without warning, sometimes accompanied by flat tires—one owner heard a snapping sound at 30 mph and found both front springs broken by 68k miles. Front wheel bearings fail and partially seize as early as 71k–73k miles, making rubbing noises and stopping wheel rotation intermittently before dealers replace them.
Corrosion is severe in salt-climate states: one owner in Ohio found front suspension cradle mounting studs rotted 25% through, making them non-replaceable short of major work. The rear suspension has documented cracks, loss-of-control events, and unfinished recalls—one owner discovered a recall repair never completed on a used purchase, while another lost vehicle control at 45 mph after a popping sound and crashed into another car, sustaining chest and neck injuries.
Persistent suspension noise—rattling or rubbing—goes undiagnosed through multiple dealer visits. Some owners report swerving during braking that dealers dismiss as tire-related, and squeaking from shocks that technicians cannot reproduce. One purchased-used 2006 Maxima had rear suspension noise that never went away despite attempts at repair.
Failure modes owners describe
Front coil spring fracture
Front coil springs fracture without obvious cause, sometimes accompanied by flat tire from the impact. Owner heard loud snapping sound from front end.
When: 68,743 miles
Symptoms owners cite: Loud snapping sound from front end; Flat tire on front passenger side; Visual inspection shows fractured coil springs
Repairs/costs cited: Dealer replaced struts, stabilizer bar, and tire
Front wheel bearing failure
Front wheel bearings deteriorate and partially seize, causing rubbing sound and intermittent wheel rotation stoppage. Occurs well before typical service life.
When: 71,000–73,000 miles
Symptoms owners cite: Rubbing sound from wheel area; Wheel stops rotating then continues; Bearing seizure risk if not caught early
Repairs/costs cited: Dealer replaced wheel bearings
Corrosion of front suspension mounting studs
Front suspension cradle mounting studs corrode severely in salt/snow climates, with up to 25% material loss. Studs are not easily replaceable and failure could cause cradle to drop.
When: Unknown; discovered during routine engine mount replacement
Symptoms owners cite: Extreme corrosion on front mounting studs; Approximately 25% of stud material rotted away; Rear studs unaffected
Repairs/costs cited: No repair performed; owner reassembled cradle with corroded studs intact
Suspension noise/rattling
Persistent rattling or rubbing noise originates from suspension area. Multiple dealer visits failed to isolate or repair the problem.
When: Early ownership; reported as early as purchase date
Symptoms owners cite: Rattling noise from underneath car; Noise persists despite multiple dealer repairs; Exact location difficult to pinpoint
Repairs/costs cited: Multiple attempted repairs by dealers; issue unresolved
Rear suspension failure with loss of vehicle control
Popping sound from rear suspension followed by complete loss of control. Owner crashed into another vehicle and sustained injuries.
When: 136,000 miles
Symptoms owners cite: Loud popping sound from rear; Immediate loss of vehicle control; Crash into another vehicle
Repairs/costs cited: Vehicle destroyed; no repairs documented
Rear suspension recall not performed on used vehicle
Used Maxima purchased with known rear suspension recall not completed. Owner later found evidence of prior rear suspension replacement but original recall work missing.
When: Discovered during routine service
Symptoms owners cite: Noise from suspension (front or rear); Recall work not performed by previous owner
Repairs/costs cited: Rear suspension previously replaced by Goodyear service; recall not documented as completed
Recalls/TSBs owners mention: NHTSA recall for power seats and rear suspension (ID mentioned but not specified)
Rear suspension issue causing loss of stability in wet conditions
Vehicle loses grip and stability in rain or wet conditions; owner spun and hit wall. References a recall on rear suspension with noted safety effects.
When: Unknown mileage
Symptoms owners cite: Loss of grip in wet/rainy conditions; Vehicle spins out of control; Instability during braking in hazardous weather
Recalls/TSBs owners mention: Recall on rear suspension referenced but not specified
Swerving during braking
Vehicle swerves left and right when attempting to brake. Dealer dismissed as normal behavior for 18-inch tires, claiming wheels follow road irregularities.
When: Early ownership (first update 04/06/06)
Symptoms owners cite: Swerves left and right during braking; Occurs at 20 mph
Repairs/costs cited: No repair; dealer attributed to tire design
Recalls/TSBs owners mention: Dealer stated this was normal for vehicle with 18-inch tires
Squeaking from front driver-side shock
Squeaking noise emanates from front driver-side shock. Dealer unable to reproduce or identify the cause despite inspection.
When: Unknown mileage
Symptoms owners cite: Squeaking from front driver-side shock
Repairs/costs cited: Dealer unable to reconstruct or identify noise source
Rear suspension subframe crack
Crack discovered in rear suspension subframe during routine tire balancing. Owner noticed no symptoms prior to discovery.
When: 45,676 miles (failure and current mileage same)
Symptoms owners cite: Visual crack in rear suspension subframe
Repairs/costs cited: No diagnosis or repair performed at time of report
Recalls/TSBs owners mention: NHTSA Campaign ID 06V046000 (Suspension: Rear) referenced
