Of the 6 model years of Chevrolet Cobalt we track for body problems, this one carries the most owner complaints on file — 32.
In a crash, head impact protection may be inadequate.
Buyer takeaway: The 2006 Cobalt has serious door latch and lock issues that leave owners trapped or unable to exit the vehicle. Water leaks into the cabin and trunk, and fuel system cracks have been reported—treat any used example as a safety risk until fully inspected by a trusted mechanic.
Driver-side doors stick shut or won't open at all, affecting vehicles from 23,000 to 129,000 miles. Owners report being unable to unlock and open the door from either the inside or outside handle, forcing them to crawl through the passenger side or wait hours for the latch to spontaneously release. Once open, the doors often won't latch closed or do so only after repeated tries taking up to 45 minutes. Some owners report temporary fixes with lubricant, but the problem comes back. After rain, both driver and passenger doors lock up for days. Mechanics struggle to diagnose—dealers frequently say they can't reproduce the issue when the car is brought in.
Power locks fail to automatically engage when driving or disengage when parked. Water soaks the rear floorboards after rainfall and pools in the trunk; one owner had the spare tire freeze to the bottom. The headliner sags from water intrusion at the sunroof. One report cites a cracked fuel supply line on the modular reservoir leaking gasoline. Lower control arms wear out at 50,000 miles. One owner reports multiple dangerous handling incidents and a spastic speedometer following mandatory recall work in 2010. Throughout these complaints, owners emphasize the safety risk of being unable to exit the vehicle in an accident or fire.

Driver-side door fails to open from inside or outside handles. Owners report being trapped in the vehicle, having to climb through passenger doors or wait hours/days for the door to release. Some report the issue occurs intermittently, others persistently. One owner noted the issue worsened after recall work in 2010. Mechanics and dealers often cannot reproduce the problem or provide lasting fixes.
When: Varies widely: as early as 23,000–32,000 miles, up to 129,000 miles. Some owners report the issue occurring on and off since 2007. One owner reported it as a recurrent issue across multiple years.
Symptoms owners cite: Door handle moves but door won't open; Interior and exterior handles both non-functional; Owner must crawl through passenger side to exit; Issue resolves after hours or days with no intervention; Popping sound heard when door finally releases; Problem intermittent; dealers cannot reproduce when vehicle is brought in
Repairs/costs cited: Mechanics have replaced door latch mechanisms and entire door locking mechanisms (full replacement costs not cited). Lubrication and penetrating oil provide temporary relief but recurrence is common. One owner replaced latch from inside after removing door panel.
Driver and passenger doors fail to latch shut. Owners report doors not catching when closed, refusing to stay shut, or latching only after extended attempts (up to 45 minutes reported). One owner was stranded with an open door unable to drive. Another had to tie the rear passenger door closed with rope. Affects 2-door and 4-door models.
When: Reported from early ownership (some since 2007) through higher mileage. One failure at 26,297 miles; another owner reports continuous issues since purchase in 2006.
Symptoms owners cite: Door closes but latch does not engage; Requires multiple attempts or extended jiggling to latch; Door stays open or flies open while driving; Latch mechanism appears to stick open; Passenger door won't latch; driver door OK at times; Seat belt or other objects appear caught in door
Repairs/costs cited: Temporary fix with lubricant or penetrating oil (WD-40 mentioned by one owner). Full latch replacement performed in some cases. One owner tied rear passenger door shut with rope rather than pay hundreds in diagnostic and repair costs. Replacement part costs cited as 'hundreds' by owners.
Doors fail to open after heavy rain. Both driver and passenger doors affected, though typically not simultaneously. Handles move but doors remain stuck. Takes days before door function returns. One owner had door locks/latches replaced but issue persisted.
When: Occurs intermittently after rain events. One owner reports multiple occurrences over time.
Symptoms owners cite: Door handle moves freely but door won't open; Occurs after rain and resolves days later with no repair; Affects either driver or passenger door; Both inside and outside handles non-functional
Repairs/costs cited: Door lock/latch replacement attempted without resolving the issue. Suggests moisture intrusion or corrosion of latch mechanism.
Door handles crack, break, or become non-functional. One report of a front passenger door fracturing completely, preventing exterior opening. Chrome plating on interior door handle flakes and becomes sharp, causing injury.
When: Reported at 26,297 miles (door fracture). Timing not specified for handle corrosion/flaking.
Symptoms owners cite: Front passenger door fractured (unable to open from exterior); Chrome plating on interior handle flakes off; Sharp flaking causes cuts to occupants; Handle feels like 'nothing is there' when pulled
Repairs/costs cited: Not yet taken to dealer in fracture case. Interior handle degradation appears cosmetic unless injury results.
Power locks fail to function as designed. Owners report doors not automatically locking when driving or unlocking when parked. Some note a ticking sound when braking, suggesting electrical or solenoid issues.
When: Timing not specified; reported as sudden onset of abnormal behavior.
Symptoms owners cite: Automatic door locking/unlocking upon shift to Park or Drive no longer works; Ticking sound when brake is pressed (not present when locks function normally); Inconsistent response from power lock buttons
Water intrudes into the vehicle interior and trunk after rain. Rear seat floorboards and trunk become soaked. Water accumulates in trunk to the point of freezing spare tire. One owner reports water coming up through both wheel wells without draining. The issue persists despite multiple repair attempts.
When: Reported from 2006 onwards; one owner had vehicle serviced nine times in four years for the same leak.
Symptoms owners cite: Both rear seat floorboards soak after rain; Water collects in trunk without draining; Spare tire frozen to trunk bottom from ice accumulation; Water rises through wheel well areas; Headliner soaked from sunroof area forward
Repairs/costs cited: Dealer has replaced interior lining and carpet once, with problem recurring. Multiple service visits (nine in four years for one owner) without permanent resolution suggests design or seal failure.
Lower control arms wear out and require replacement at low mileage. Mechanic reports seeing this problem frequently on 2006 Cobalts.
When: 50,000 miles
Symptoms owners cite: Noise from front of car when turning or hitting small bumps
Repairs/costs cited: Both lower control arms required replacement at 50,000 miles.
Plastic supply line on the modular fuel reservoir assembly cracks, causing fuel to leak onto the ground. Owner reports other Cobalts in other states have been recalled for the same issue, raising concerns about why all Cobalts were not recalled.
When: Mileage not specified
Symptoms owners cite: Crack in plastic supply on modular reservoir assembly; Gasoline leaking to ground
Recalls/TSBs owners mention: Owner states some Cobalts in other areas have been recalled for this same issue, but not this owner's vehicle.
