NHTSA — Visibility: Sun Roof Assembly 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.


definitely annoying

Both sides of the panoramic sun roof has come unattached and leaked in my floor on multiple occasions and is very distracting getting dripped on and will eventually cause a wreck. Worst car ever!!!!! also the brakes are terrible. I've done so much work myself to my brakes and had shops do some too because I cannot afford to replace the [xxx] through a shop ever 6 mo. My passenger side rotor locked up for no reason 2 diff. Shops couldn't find a reason. The bleeding process is ridiculous and the brakes do not last more than 4-6 mo tops no matter how you brake on them.

Both the driver & rear passenger have water damage due to a faulty mfgd sunroof. It leaks when it rains and when I contacted GM they said that they cannot cover the diagnostic charge for the vehicle inspection.

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.
