My brake lights stick on until I am traveling at about 70 mph, then they begin to flash until I decelerate. I have replaced brake switch, replaced battery, replaced alternator, tried dielectric tube, and had the brake light malfunction recall part replaced. This problem is costing way too much time and money. What could this be? What else can I try to fix it?
I am thinking that the Brake Control Module has not gone through the relearn process. The dealer that took care of the recall should have relearned the brake pedal home position according to the recall notice. I believe the best course of action would be to contact the dealership service manager directly and politely express your concerns over the recall not being performed correctly and that you would like a second look for “SAFETY” reasons. I am certain you will be put on the schedule quickly.

Recall Number: 14V252000
Recall Date: 05/14/2014
Component: ELECTRICAL SYSTEM:WIRING
Problem Summary: General Motors LLC (GM) is recalling certain model year 2004-2012 Chevrolet Malibu vehicles manufactured May 16, 2003, through October 11, 2012, 2004-2007 Malibu Maxx vehicles manufactured June 25, 2003, through April 5, 2007, 2005-2010 Pontiac G6 vehicles manufactured May 26, 2004, through January 4, 2010, and 2007-2010 Saturn Aura vehicles manufactured April 24, 2006, through May 26, 2009. In the affected vehicles, increased resistance in the Body Control Module (BCM) connection may result in voltage fluctuations in the Brake Apply Sensor (BAS) circuit. These fluctuations can cause one or more of these conditions: the brake lights to illuminate without the brake pedal being pushed; the brake lights to not illuminate when the pedal is pushed; difficulty disengaging the cruise control; moving the gear shifter out of the ‘PARK’ position without pushing the brake; and disablement of crash avoidance features such as traction control, electronic stability control, and panic braking assist features.
Consequence: Any of the above failure conditions increases the risk of a crash.
What Owners Should Do: GM will notify owners, and dealers will attach the wiring harness to the BCM with a spacer, apply dielectric lubricant to both the BCM and harness connector and the BAS and harness connector, and will relearn the brake pedal home position, free of charge. The manufacturer distributed an Interim letter to customers on July 14, 2014. The recall began on August 18, 2014. Owners may contact General Motors customer service at 1-800-222-1020 (Chevrolet), 1-800-762-2737 (Pontiac), 1-800-553-6000 (Saturn). GM’s number for this recall is 13036.
