The 2008 HHR has a consistent pattern of airbag deployment failure across multiple crash types. Owners describe frontal collisions, side impacts, rollovers, and rear-end crashes where airbags did not deploy despite impact severity. Speeds ranged from low-speed rear-ends to 45 mph collisions. Injuries sustained include head trauma, neck and back damage, concussion, shoulder injuries, hip fracture requiring surgery, and one fatality. Vehicles often were totaled, yet no airbag activation occurred.
Separately, owners report airbag warning lights and "Service air bag soon" messages appearing at high mileage (around 80k–143k miles). Dealers identified defective airbag modules needing replacement, but in at least one case the parts were discontinued by the manufacturer and unavailable. Another owner reported GM refused warranty repair.
One owner experienced spontaneous side curtain airbag deployment during low-speed reverse movement (5 mph) with no impact, injuring them when the seat belt tightened.
Additional complaints note the frustration of receiving airbag recall letters but being unable to obtain replacement parts. Owners also reported dealership scheduling obstacles preventing them from completing required safety recalls for months.
Failure modes owners describe
Airbag failure to deploy in crashes
In multiple crash scenarios—frontal impacts, rollovers, side collisions, and rear-end impacts—airbags completely failed to deploy despite impact severity warranting deployment. Owners reported injuries including head trauma, neck/back damage, concussion, shoulder injuries, hip fracture, and one fatality, all occurring in accidents where airbags should have activated.
When: At various mileages ranging from 35,430 to 143,000 miles; crashes occurred at speeds from 5 mph (rear-end) to 45 mph, and in rollover events.
Symptoms owners cite: No airbag deployment in frontal collisions; No airbag deployment in side-impact collisions; No airbag deployment in rollover accidents; No airbag deployment in rear-end impacts; Vehicle sustains major structural damage despite deployment failure
Repairs/costs cited: No repairs documented; vehicles were totaled or destroyed. One owner noted dealer wanted to charge them to test the system after an accident.
Recalls/TSBs owners mention: One case states GM was made aware. One owner referenced a recall notice regarding roof rail airbags but reported no deployment occurred. Recall letter received in #4 indicated parts were unavailable.
Airbag warning light and module faults
Check airbag warning indicators illuminated on vehicles, with some accompanied by 'Service air bag soon' messages. Dealers diagnosed defective airbag modules that required replacement but were either unavailable (discontinued by manufacturer) or repair was refused without warranty coverage.
When: At 80,900 miles (#3), 90,000 miles (#13), 128,000 miles (#11), 143,000 miles (#12).
Symptoms owners cite: Check airbag warning light illuminated; Service air bag soon message displayed; Error message displayed on message board; Warning light remains continuously lit
Repairs/costs cited: Two unknown modules identified as defective and requiring replacement in #3 but parts were no longer manufactured. In #12, dealer diagnosed airbags needed replacement but manufacturer refused to repair for free.
Recalls/TSBs owners mention: Manufacturer informed owners that defective modules had been discontinued (#3). No recalls found to apply (#11). No recall associated with #12.
Inadvertent side airbag deployment
Side curtain airbags deployed unexpectedly during low-speed maneuvering (reversing at 5 mph) with no impact or collision. Seat belt tightened severely, injuring the driver.
When: At 35,430 miles.
Symptoms owners cite: Side passenger curtain airbags deployed without impact; Seat belt pulled tight, injuring driver; No collision or contact with other vehicles or objects
Repairs/costs cited: Vehicle towed to dealer; no diagnosis provided at time complaint was filed.
Recalls/TSBs owners mention: GM called and stated they were investigating the failure.
Recall parts unavailable
Owner received airbag recall notice but could not obtain replacement parts because they were no longer manufactured. Vehicle could not be repaired to address the safety defect.
When: Condition noted as of 01/09/17.
Symptoms owners cite: Received recall letter for defective airbags; Replacement parts discontinued and unavailable
Recalls/TSBs owners mention: Recall letter issued; parts were not available to complete the repair.
Dealership inability to complete recall repairs and scheduling difficulties
Owner attempting to complete two safety recalls experienced extended delays and poor customer service from dealership and GM customer assistance. Over three months of attempts to schedule weekend or obtain loaner car were unsuccessful, leaving owner driving unsafe vehicle without viable alternative.
When: Complaints filed 12/1/2016 covering previous attempts from 4/8/2015; issue unresolved after three months of follow-up.
Symptoms owners cite: Unable to schedule recall appointment for convenient time; Dealership unable to provide loaner vehicle; Repeated broken promises and lack of communication; Owner expressed feeling unsafe driving vehicle
Recalls/TSBs owners mention: Two outstanding safety recalls identified; owner contacted Chevrolet Customer Assistance Center 12/1/2016 but received no productive help in scheduling or obtaining loaner.
