Mysterious O2 Sensor Problem

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.

If someone else with a G6 has this issue please report what you did to solve it. And no I don't have a bad O2 sensor. I have a post-cat O2 sensor which sits on the front of the engine that just stopped sending one day. I took it the dealer and paid $80 for them to tell me further diagnosis is necessary sensor is not getting voltage. So I took it to another dealer who also told me they had no clue what was wrong and the wanted more money to diagnose it. I checked the wiring and the harness, cleaned the connector still does not get voltage. So I decided to let it go, it has no effect on the cars operation other then I can't use my remote start. But the idiot light is annoying and the fact my remote start does not work. Anyone else with this issue. I'm thinking the computer needs re-programmed or replaced because my computer does not see the start cycle sometimes when I start the engine all controlled by the ECM. Anyone else with these issues?
