NHTSA complaint #10594118, filed 2014-05, 52,685 miles“My taillight assembly is 1/3 filled with water, due to a broken seal (which is allowing water to enter). Due to the broken seal, the water damaged the entire l/r taillight assembly, rear turn signal (drivers rear), the lamps, bulbs, flasher, and switch. Several mechanics said that the broken seal in my 2009 chevy Cobalt, appears to be a Chevrolet manufacturer's defect.”
NHTSA complaint #10484071, filed 2012-11, 24,000 miles“Headlights side marker cover came off on both headlamps not at the same time short time after the first one then the right side came off causes glare. Power locks do not function any more with buttons only function with gear shifter sometimes locks will go lock to unlock by themselves multiple times with or with not driving the car. Contacted GM and they informed me that the headlights are not recalled on my year but they are for the 2005's. Obviously they did not fix the problem from then. I will not by another GM product ever.”
NHTSA complaint #10452315, filed 2012-03, 55,000 miles“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.”
NHTSA complaint #11119552, filed 2018-08, 137,000 miles“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.”
