Summary
The Pontiac Sunfire has 16 recalls spanning the 1995–2004 production run, with the most serious being a 1996 model year airbag defect where incorrect calibrations in the airbag computer can trigger deployment in a low-speed crash or when something strikes the floor pan, firing the airbag at the occupant unexpectedly.
The 1996 model year also has two other significant issues: a rear suspension trailing arm bolt that can break while driving and affect vehicle control without warning, and an accelerator cable that can kink, stick, or break and cause unwanted acceleration or a complete loss of throttle. There is also a separate concern on 1996 vehicles where exposure to substantial water intrusion can cause the driver or passenger airbag to deploy on its own, without any crash occurring.
On the 2004 model, the passenger-side rear seatbelt may have been installed with an incorrect bolt and nut, and in a severe crash the upper anchorage can pull free. The 2003 model year has a rear light bulb socket issue where missing grease allows electrical arcing that can knock out the brake lights and turn signals. The 2000 model has an instrument panel backlighting fault that can leave the driver unable to read gauges and controls at night after adjusting interior light intensity.
The 1997 model year has two concerns: compact spare tire rims that may not conform to dimensional standards and can allow the tire to separate from the rim if underinflated, and mislocated welds at the left rocker panel that can reduce door strength in a side crash.
Going back to the earliest production years, 1995 models have a front suspension lower control arm where missing welds can cause the front bushing assembly to separate from the arm, reducing steering control suddenly. A separate 1995 issue involves the ignition switch overheating when the key is held in the start position too long, which can start a fire in the steering column even after the key is removed. The powertrain control module on 1995 vehicles can also absorb moisture from road salt corrosion, causing rough running or engine stall. Some 1995 vehicles have hazard warning lights that fail to flash when the switch is activated, and on automatic-transmission models the instrument panel trim plate can sag and cover the shift indicator display.
