I have had an utter nightmare with my 06 STS. It has been in and out of the garage for 3 weeks now...First the front pinion seal, then the rear differential seal, then the front pinion seal started again....The front pinion seal was replaced and continued to leak....The flange and pinion seal were replaced and the leaks stopped. Now the dual zone heat is not working and the entire radio system needs to be replaced since the Nav is not functioning properly...The voice recognition also doesn't function properly and my engine is making a loud noise on a cold start...Shouldn't this justify a repurchase or replacement...
Mine has been out of service more than 30 days....I really love the STS but hate what I am going through.....I believe that probelms should be addressed when they exist. Like the pinion seals and the differential leaks...I also think that an item like Navigation shouldn't be included if it doesn't work 100%. It is misleading and very frustrating for the customer who spends the extra money to get these advanced electronic components.
See my post in Wind noise & squeaking steering wheel.
The best advice is to use the arbitratin process thru the BBB. GM will fight you all the way. Once you get an arbitration date set they will re-evaluate their position. It is better to voluntarily buy back a car than have it tagged a "lemon" and have the law make them buy it back. All lemons must be labelled when they are re-sold.
The dealership claims that there is a new software update to address the poor voice recognition and bluetooth issues....The TSA is 05-08-126-001a...Does anyone know about this?...It is very hard for me to believe that a software upgrade will solve all these issues. This is a hardware issue....Anyways, I hope to get this updated on MOnday but in the meantime my car is being towed to the dealership since it started vibrating when going over 40mph today...The dealership thought it might be snow caught inside the 18" wheel wells but I cleared all 4 wheels out and it is even worse...It doesn't get any worse than this....
I googled 05-08-126-001 and found a TSB from Feb 2005.This sounds like the reprogram that was applied to my car in the summer of 2005 to improved the outgoing voice quality of bluetooth. It changed some of the bluetooth functionality, but did not fix the problem that I had. It also wiped out all of my navigation settings.
I was told at that time that there would be another navigation reprogram available in October 2005 to fix the voice recognition. I have never been notified about this second update and when I ask about it I get the "no solution at this time" response. This is a big loose end for me because I still don’t want to spend a lot of time organizing my navigation marked points just to have them wiped out when they try to fix the voice recognition. I would really like to know if and when this second reprogram will be available to fix voice recognition and really fix the bluetooth outgoing voice quality. I can’t get an answer from the dealership.
