The 1990 Buick Reatta has 3 recalls, the most serious being two related airbag sensor defects that can delay driver-side airbag deployment in a crash, increasing the risk of injury.
The airbag's forward sensor may have been built incorrectly in one of two ways: a reversed wiring harness connection or other internal misassembly. Either problem can prevent the airbag from firing at the right moment, meaning the bag may deploy too late to fully protect the driver. The third recall involves the brake system warning light, which may not illuminate when the ignition is on, the parking brake is applied, and the transmission is in Park or Neutral, leaving the driver without a visual cue that the parking brake is engaged.
