There are 5 owner-reported lighting complaints for the 2009 Chevrolet Cobaltin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
OEM headlights had become dim and one could no longer be aimed, so I ordered these replacements through Amazon. I paid $92 to have them installed, and the mechanic let me know that the high beams could not be activated, except by holding the turn signal, making it dangerous to steer. In addition, when the headlights are on they create so much RF, the radio no longer gets most AM or FM stations. The mechanic confirmed, they are wired incorrectly, but did not wish to attempt to rewire them.
HEADLIGHTS FAILING WITHIN 6 MONTHS OF REPLACEMENT. BOTH DRIVER AND PASSENGER SIDE. LOW BEAM. I HAVE REPLACED BOTH SIDE AT LEAST 3 TIMES IN LAST 75,000 MILES.
THE AIRBAG INDICATOR LIGHT FLASHES INTERMITTENTLY.
TURN SIGNAL WILL NOT CUT OFF AFTER TURNING.
