Owners of the 2006 Altima describe a suspension that fails in multiple ways. The most dangerous: rear control arms detaching at highway speeds (around 60 mph in documented cases), sometimes with sparks visible and the vehicle becoming inoperable. One independent mechanic noted the control arm was welded aluminum-to-metal and couldn't be repaired. Others report the rear suspension sitting abnormally low compared to the front, and in one case, dropping audibly while driving at 55 mph.
Steering is another chronic complaint. Multiple owners report the steering wheel pulling hard to the right or left regardless of speed, with the problem persisting even after dealers rotated tires, balanced them, replaced them entirely, and performed front-end alignments. One owner experienced steering lock-up at 60 mph requiring forceful input to unlock.
The rear floor pans rust through completely—holes large enough to put a foot through—on both driver and passenger sides. Nissan issued a technical bulletin with a repair kit in 2015 but never issued a recall, despite this being a documented issue across 2002–2006 Altimas.
Rear wheel instability shows up as wobbling at speeds above 55 mph with scrubbing noise, leading owners to buy multiple tire sets chasing a fix that appears to be suspension-related. One owner mentioned purchasing four sets of tires. Owners also report wheels scraping wheel wells hard enough that only two people fit safely in the back seat.
The 2006 Altima shows up on recall lists for suspension (NHTSA 06V046000), yet many owners never received notice.
Failure modes owners describe
Rear Suspension Cracking/Failure
Rear suspension components—particularly control arms and brackets—crack or detach at highway speeds, with some cases involving welded aluminum-to-metal joints that fail structurally. Owners report the suspension dropping or feeling loose, sometimes with sparks observed from the rear of the vehicle.
When: Between 180,000–213,000 miles; some reports at much lower mileage
Symptoms owners cite: Rear control arm detachment while driving; Suspension drops audibly/noticeably; Sparks from rear of vehicle; Vehicle becomes inoperable after failure; Rear suspension sits abnormally low compared to front
Codes mentioned: NHTSA 06V046000
Repairs/costs cited: Independent mechanic noted control arm welded from aluminum to metal and could not repair; dealer advised replacement needed. Catalytic converter also failed in one case due to related engine issues.
Recalls/TSBs owners mention: Dealers advised vehicles were not included in recalls despite owners identifying NHTSA campaign 06V046000. Manufacturer advised no recalls applied.
Front-End Steering Pull and Lock-Up
Steering wheel pulls consistently to the right or left while driving, sometimes locking up at highway speeds. Multiple dealer alignment, tire rotation, balancing, and tire-size corrections do not resolve the issue. One owner reported steering locking at 60 mph requiring aggressive steering input to unlock.
When: Reported across early ownership (100–2,011 miles noted)
Symptoms owners cite: Steering pulls persistently to right or left; Steering wheel locks up at highway speeds (60 mph); Problem worsens after repair attempts; Difficulty controlling vehicle during pull; Pulling occurs at any speed when driving
Repairs/costs cited: Tire rotation, balancing, front-end alignment, and complete tire replacement performed but did not resolve. One dealer blamed wrong-size tires (though dealer mounted them at sale).
Recalls/TSBs owners mention: Manufacturer case #5591789 issued; manufacturer notified in at least one case.
Rear Suspension Clunking and Wheel Scrape
Rear wheels scrape against wheel wells during normal driving, severely limiting rear-seat occupancy. Owners also report loud clunking from rear suspension at highway speeds and instability that requires constant steering corrections on interstates even at moderate speeds.
When: Onset early in ownership; some complaints at 60,000+ miles
Symptoms owners cite: Rear wheel scrapes wheel well; Can only fit two people in back seat due to scraping; Car drifts left and right without steering input; Requires constant steering corrections on interstate; Loud clunking noise from rear suspension; Vehicle unstable even at 60–70 mph on interstate
Repairs/costs cited: No repairs documented in complaints; one owner states clunking requires engine replacement (though likely separate issue).
Recalls/TSBs owners mention: Owners mention multiple recalls on exterior lighting and rear suspension, but never received recall notices.
Rear Floor Pan Corrosion and Perforation
Passenger-side and driver-side floor pans rust through completely, creating holes large enough for a foot to pass through. Nissan issued a 13-page technical bulletin (titled 'Floor Panel Repair') in July 2015 describing a repair kit, but no recall was issued. Corrosion is documented as a long-standing issue for 2002–2006 Altimas and 2004–2008 Maximas.
When: Develops over ownership; noted at routine maintenance visits
Symptoms owners cite: Rust and corrosion visible on passenger-side floor pan; Complete perforation of floor pan (foot can pass through); Driver-side and passenger-side floorboards rotted out; Debris falls through floor while driving
Repairs/costs cited: Nissan issued technical bulletin 7/6/2015 with repair kit but no recall. No owner reports successful repair through dealership.
Recalls/TSBs owners mention: Nissan developed repair kit per technical bulletin but did not issue formal recall; history of similar issues on Pathfinder and noted in 2002–2006 Altimas and 2004–2008 Maximas.
Drive Axle Slipping/Detaching from Transmission
Right front axle slipped out of or detached from transmission, initially after just two weeks of ownership. After warranty repair, the same axle failed again within weeks, accompanied by transmission warning light coming on and off.
When: Two weeks after purchase; recurred one to two weeks after first repair
Symptoms owners cite: Right front axle came completely out of transmission; Automatic transmission warning light cycling on and off; Starter/cranking system acting up after repair
Repairs/costs cited: First repair performed under 30-day dealer warranty; axle 're-seated' by tow truck. Failure recurred shortly after, suggesting inadequate repair or persistent design issue.
Recalls/TSBs owners mention: Dealer offered to fix under warranty; owner later withheld payment and cited recall list concerns, but received no manufacturer response documented.
Rear Tire Wobble and Separation Concerns
At speeds above 55 mph, rear tires wobble and produce scrubbing noise, creating the sensation that tires are about to detach. Owner has replaced tires four times, attributing repeated failure to suspension rather than tire defect.
When: Onset at highway speeds (55+ mph); recurring across multiple tire sets
Symptoms owners cite: Rear tires wobble at 55+ mph; Scrubbing noise with wobble; Sensation tires are about to fall off; Recurs even after multiple tire replacements
Repairs/costs cited: Four sets of tires purchased; owner suggests suspension issue rather than tire defect.
