NHTSA — Engine And Engine Cooling: Cooling System Problems

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.

I brought a 2006 Pontiac G6 November 2006. The car has given me problems since I brought it. Rattling noises everytime I turned on the heat. When I turned my wheel there is a clicking noise. And also my check engine lights comes on everyother day. I took it to the dealer they say nothing is wrong with the car. Can someone please help me.

I purchased a 2006 Pontiac G6 April 21, 2007. Afterwards I started noticing a popping noise when I would turn, so I took the car in to be serviced 9-2007. They replaced the tie rod adjuster & reset toe-in, but again I still had the same problems. Also I've been having problems with the window leaking on the drivers side. The ac / heater blower stays on when car is not on which caused my battery to drain so I took the car in again April 11, 2008 and they told me they replaced the drive shaft & blower motor resistor but still having the same problems. Now I am noticing that the passenger side air bag indicator doesn't register when someone is in the front seat w/ seatbelt on. Sometimes it comes on when there is no one in the seat. The starter continues to crank while trying to start car and sticks when the car is started. Last but not least, after purchasing fuel the car gas gauge drops drastically only after going about a mile or two.
