Although my 2008 Bu is technically out of warranty (75,000km or approx 45,000mi), it has such a long history of issues that my Chev dealer has been providing goodwill work for the last 15,000km. I took it in again this week for ......you guessed it....front end clunking! Rear-end is also still squeeking (when roads are dry). So now that roads are winter-wet, I have to wait for dryer weather to take it in again to find the rear squeek (to be covered by goodwill).
My Bu has had the following warranty work including many items under goodwill: New front bump stops, left strut, new rack (20,0000km ago), new intermediate steering shaft (20,000km ago), rear links, new RH side door actuators, ISS grease pack this past week(even though the ISS has only 20,000km), oxygen sensor and a few other issues.
I usually leave my car at the dealer when having it serviced. This past week when the car was in for a new grease pack for the ISS (to fix the clunking), the dealer called to tell me that the power steering needed to be flushed because the oil was all black. According to the tech, this supposedly often happens with the new generation Bu's original power steering oil because it is of inferior quality compared to what they now use? I was very skeptical about that but agreed to pay for the power steering flush because of all the goodwill work they have done (I kind of felt obligated and didn't want to seem like a cheapskate). Keeping in mind the fact that rack was replaced approx 20,000km ago (12,000mi), here are a couple of questions:
- Isn't the power steering oil normally replaced when a new rack is installed?
- If yes, how can the power steering oil turn black in such a short while (20,000km or approx 12,000mi)? Shouldn't I be concerned that the power steering has internal issues if the oil had to be replaced?
- Does GM now use better-than-stock oil when they flush out the system as I was told?
- Has anyone ever had their power steering oil turn black (I have had 8 cars without this ever happening) within such low mileage...in fact never had power steering oil turn black ...period?
- What is the recommended maintenance on the power steering system?
- Am I correct in feeling like the dealer was simply trying to recuperate some costs ($125 for the flush) given all the goodwill warranty work ?
Pretty soon, I'll have to pay rent for all the time my car spends at the dealership
!!!! Luckily we have a second car (2003 300M Special) that has NEVER had any issues other than regular maintenance and a couple of very minor things.
BTW, There is still noise coming from the front end!
