What stands out
No new NHTSA airbags complaint has been filed on this vehicle in over 12 years — the issue may be aging out of the active population.
The failure pattern owners describe
Owners report three distinct airbag problems in the 2005 Deville. One vehicle deployed the front passenger airbag at 75 mph with no impact or warning, injuring the owner. Dealers were stumped—one said they'd never seen an airbag deploy without a crash. The manufacturer suspected undercarriage damage triggered it but declined to repair.
More concerning: several owners report airbags that failed to deploy in real collisions. One was hit head-on and the ignition cut off; another was rear-ended in a chain-reaction pileup; a third hit a parked car at 70 mph after brake failure—none deployed. These vehicles were destroyed or seriously damaged, and owners sustained injuries requiring medical attention or surgery. GM denied the head-on case was related to a known recall.
Finally, owners report persistent airbag warning lights starting around 40,000 miles, sometimes staying on for a minute or two after startup. One dealer told an owner this wasn't covered under recall 14V355000, then charged $1,300 to fix it. Another owner's dealer replaced the passenger seat airbag module and harness. Some manufacturers refused assistance; some never informed the maker.

What owners are reporting 4 most recent
I was hit head-on. The ignition turned off after being hit and the seat- belts did not deploy. I stopped and my hand was on the horn but the person did not slow down or stop.I was on a city street.I was hurt and had neck surgery. Gm is telling me they will look back into it after denial that was it due to the recall. They sold the car as salvage when the insurance totaled it. The car was then…
Airbag light kept coming on when the car was turned on. Sometimes this would stay on for 1 or 2 minutes. Called the dealer and they said it was not on the recall. When told them what it was doing, they said not to drive it & get a loaner. I have to pay $1300 to have this fixed. This should have been fixed by the company not by me. *tr
