NHTSA — Exterior Lighting: Brake Lights Problems

CarComplaints.com Seal Of Avoid Like The Plague

CarComplaints.com Notes: The 2005 Pontiac G6 has major problems with two areas fairly critical to the act of driving... steering & safety.

The 2005 G6 has a major defect trend with electronic power-assisted steering failure. The power steering cuts out while driving, making it extremely difficult to steer. G6 owners typically report spending $600 - $1,200+ to fix the problem, replacing either the entire steering column or the power assist motor.

In March 2010, GM recalled 1.3 million vehicles for this exact problem "...after receiving 1,100 complaints of power steering failures." However the 2005 G6 wasn't included in that recall.

In July 2010, GM issued a "Special Coverage Adjustment" — TSB #10183 — covering "certain" (not all) 2005, 2006 & 2008 Pontiac G6's for power steering problems, up to 10 years/100k miles.

As of early 2013 the NHTSA had 300+ steering complaints on file for the 2005 G6, with 12 crashes & 4 injuries. The NHTSA closed their initial investigation in 2007, having determined that losing your power steering going over 15-20 mph isn't a big deal & that most crashes occurred at slow speeds, so not a safety risk. Ridiculous? Yep, we think so too.

The 2005 G6 also has an expensive problem with "popping" or "clunking" noises when turning, & that issue extends to newer model years as well.

Factor in the 2005 Pontiac G6's poor side impact protection & you end up with a vehicle you should steer clear of.

I have been having issues with the brake lights on my vehicle for almost the entire time I have owned the vehicle. As it has been revealed in a recall for this vehicle (NHTSA campaign number: 09V036000) the brake lights do not function properly -- they turn on when I am not hitting the brakes and turn off when I do hit the brakes. In July 2009 I thought I had the issue fixed when I took the car to a GM dealer to be repaired under the recall. However, despite the vehicle being fixed under the recall the brake lights still do not work properly. I just got approached by someone following me a couple of days ago that my brake lights are not working again.

My 2005 G6 brake lights stay on 24/7 very hard to get out of park. I cannot use the cruise control. The position of the pedal is affecting everything. It's unsafe! they are telling me I need to pay $300.25 to replace the BCM. Nothing else is wrong but what they state in the recall papers. Why do I have to fix a problem they recalled??

Improper operation of the brake lamps. While using my brakes I discovered that the brake lamps would not illuminate. Also, the brake lamps would illuminate when the brake pedal was not applied. I called GM dealer and they indicated my vehicle was not part of their recall. It is an extremely dangerous condition and dealer informed me that they had no idea how much it would cost to fix it until they did diagnostic testing. When I explained it is the same condition as recall# 09V036000 they just kept telling me that my vehicle is not part of the recall. GM needs to expand the recall to all Pontiac G6 vehicle, not just those manufactured in January 2005.

According to recall #08317 by General Motors, the brake lamps on a 2005 Pontiac G6 will not work properly due to fretting corrosion in a wiring connector within the body control module. My vehicle was taken in to van Chevrolet of Kansas City, mo to fix this issue, and was told due to the fretting corrosion the BCM needs replaced. I was told by this dealership they could not replace the BCM without a fee and refused to make the necessary corrections to solve this problem and allowed the vehicle to leave the shop with the brake lights being defective. This would not need to be replaced if not for the fretting corrosion as stated by the recall mentioned above. General Motors and any GM dealerships have a responsibility to fix this issue.

I have had multiple problems with my brake lights. At first they worked in reverse, then stayed on all the time and the third time they are not working at all now. I had the pedal position sensor and brake light switch replaced in 10/08. In 10/09 the brake lights stayed on at all times and they said there was a bulletin about greasing the part which they did. Now, 8/10 my brake lights are not working at all again! I called the only local dealership who can't fit me in for at least one week. Updated 02/06/12 updated 02/08/12

2005 Pontiac G6 has problems with the brake lights, brake pads, and rotors. The day after purchasing the vehicle, the consumer had to take it back to get an alignment and have the rotors replaced. In June 2008, the consumer took the vehicle to the dealer because the brakes were making a noise. The dealer was unable to duplicate the issue. Two weeks later, the front pads had to be replaced because they were worn. The sunroof had to be repaired due to a rattling noise it was making. After the sunroof was repaired, it began to make a different noise. A technician determined a pipe had ruptured. The brake lights were on when the vehicle was in drive. The consumer then received a recall letter in the mail regarding the defective brake lights after already paying for a sensor that didn't resolve the issue.

I have a 2005 Pontiac G6 GT. The brake lights, with no known cause, began to stay on when accelerating and turn off when the brake was hit. This occurred day and night without any known cause. The bigger problem was that the lights worked sometimes, making it hard to diagnose a problem. I have yet to find a mechanic who has been able to determine and correct the brake lights.

The brake lights are continually on, other driver's think the consumer is braking at all times. The vehicle has been to the dealer 7 times and changed switches in the foot pedals and brakes. They say it has codes of brake slipping and they still cannot correct the problem.
