NHTSA — Engine 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.

Hearing noise under the hood. Took to dealer garage, they determed that rods & pistons failing. May only have 5 thousand miles left if lucky before total engine failure.

While driving home my alarm system light blinked on then stayed on. The headlights shut off and turned on. After I parked the car and turned off the engine the theft deterrent system activated and my car would not start for 45 mins. I followed all reset procedures nothing worked. Had to disconnect and reconnect alarm. Now alarm will not work and the trunk/doors open or unlock randomly, radio turns off, lights turn off. Problem has been happening for a few weeks now noone in town knows how to fix.

While driving my vehicle I experienced a loss of power steering and a loss of acceleration while driving on a busy main street I was forced to come to a complete stop. My current speed before loss of power was 45 mpg and immediately dropped to 0 miles as the dashboard read power steering engine disabled. Luckily my emergency lights still worked and I avoided a crash but I do hope that GM resolves this issue and makes a recall as soon as possible to prevent casualties and fatalities.
