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 Owner Comments

  • 65,000 miles


The contact owns a 2006 Pontiac G6. While driving approximately 55 mph on normal road conditions, the vehicle came to a complete stop. He applied pressure to the accelerator pedal and, immediately, the engine power drastically reduced. The "traction control", "engine power reduced", and "check engine" warning indicators illuminated on the instrument panel. The failures occurred intermittently. The vehicle was taken to an authorized dealer for diagnostic testing and they stated that the failures were related to the throttle body. The technician cleaned the throttle body, but the failures recurred the same day. The vehicle was taken back to the authorized dealer that recommended the throttle body be replaced, but they were unable to guarantee that the remedy would prevent the failure. The manufacturer was notified of the failures. The contact is waiting on a response from the manufacturer. The vehicle has not been repaired. The failure mileage was 65,000 and current mileage was 65,400.

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)....

The contact owns a 2006 Pontiac G6. While driving 65 mph, the steering column locked up for a brief moment. When it unlocked, the vehicle spun out of control and crashed into a pole on the side of the interstate. A police report was filed. The insurance company did a crash inquiry and, according to their information, there were nineteen similar failures. The powertrain was unknown. The current and failure mileages were approximately 50,000.

I purchased a new 2006 Pontiac G6 in Jan 06, at 3000 miles the car was in the dealership service center with low coolant, it's been in the 2 times since and is going back for the same reason 10/16/06. Total this car has been in the service center 7 times including this trip. This will be the fourth time for coolant leak. 1 for an electrical shortage, 1 for a pinched brake line, and 1 to repair items the service center left undone. 7 times in the service center in 9 months, wow sounds as if something may be wrong huh? I have contacted the GM 800 spoke to 5 different reps they seem to be of the opinon nothing is wrong with it.
