NHTSA — Power Train Problems

2006 Pontiac G6 (Page 3 of 3)

CarComplaints.com Seal Of Avoid Like The Plague

CarComplaints.com Notes: The 2006 Pontiac G6 has major problems with two areas fairly critical to the act of driving... steering & safety.

The 2006 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 2006 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 this power steering issue, up to 10 years/100k miles. However a large number of 2006 G6 owners have reported they were not covered by this campaign, based on VIN#.

As of late 2013 the NHTSA had well over 700 steering complaints on file for the 2006 G6, with 21 crashes & 12 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 2006 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 2006 Pontiac G6's poor side impact protection & you end up with a vehicle you should steer clear of.

2006 Pontiac G6 V6 stalling while in drive and park. There were no events leading up to this and has occurred six times. While driving at low speeds or in park, the car will suddenly turn off and the check engine light will illuminate. The brake and steering will also lock up. Upon turning the car off and placing it in park it will restart, I have placed the car in the shop two times to have this fixed. Last time (May 18) was to tape engine wires and clean the fuel injector, which they said would fix it. This repair cost me $500. Since then the problem has increased, happening three times in the past three days. I have contacted Pontiac numerous times but they are unwilling to help. Both my GM dealer and I have used a code reader to see if the car is throwing out a code when it stalls but nothing can be found. My car has quickly become a liability to myself and those around me, as the last time I stalled I almost drifted into a busy intersection. Something needs to be done to fix this problem, which is apparently quite widespread in 2006 G6S.

I have a 2006 Pontiac G6 that has started to make a clunking sound when I turn and makes this weird humming sound when I apply the brakes (at times), when I press the gas (at times), when I turn (at times), and sometimes when I am just driving forward, which makes it very hard to pinpoint exactly where the problem is coming from. I have read numerous other complaints about this "clunking" sound when turning and feel this issue should be addressed and resolved asap. J from

My problems started with this car before I even got home with my new purchase. I had 2 children in the car and the tire blew off the rim damaging the fender notes from the invoice state that "parts and labor to be billed to 67D 67F, cannot warr tire that has been mounted wrong on 1st repair" then on 6/26/06 paint was refinished due to clear coat peeling on the hood. On 11/06/06 radio does not play cd's and radio was replaced. 3K mile service with motor silk. Also airbag light was staying on and they said they found a wire to SDM loose and repaired wire. Also right rear tire was leaking air. 4/20/2007 engine was knocking loud when first started in morning at that time they replaced the lifters. The engine was replaced shortly after that and again had problems with the air bag light staying, dealership again said it was a sensor but this is only a few of many issues I've been having with this car. Please contact me and we will go through each one or you can contact the dealership where this lemon was purchased and request the records (I have a copy too)....

Gear shift controller gets stuck in drive. Dealership said it was the brake light system, that the lights were not working when pressing the brakes.
