Dangerously Misleading Brake Lights Act Possessed

For years Pontiac G6 owners have said their brake lights are possessed. As it turns out, they may be on to something.

Think of how brake lights are supposed to work – then reverse it. The brake lights turn on when you’re cruising and turn off when you actually stop the car. That’s the simplest way to describe this extremely dangerous problem.

The real reason this is happening has to do with voltage fluctuations in the brake apply sensor circuit. The fluctuations create erorrs in the circuit that can cause problems with the brake lights, cruise control, traction control, electronic stability control (sensing a control theme here?) and panic braking assist operation.

The problem is known to have caused thousands of complaints and at least 13 accidents.

An Investigation Leads to a GM Recall

2014 was the “year of the recall”, especially for General Motors. Thankfully this dangerous issue was covered in May 2015 as part of a recall of 2.7 million vehicles for various problems. Here’s a timeline of how an investigation led to a recall:

  • February, 2013: The National Highway Traffic Safety Administration (NHTSA) opened a “recall query” following 314 complaints of brake light problems.
  • March, 2013: NHTSA expands its investigation to include the 2004-2009 Chevrolet Malibu and 2007-2009 Saturn Aura.
  • June, 2013: NHTSA expands its investigation to include even more 2005-08 Pontiac G6 vehicles.
  • May, 2014: GM recalls 2,400,000 vehicles, including the 2005-2010 Pontiac G6, for corrosion problems in the wiring harness. NHTSA says increased resistance in the body control module connection can cause voltage fluctuations that cause electrical problems.
