Replying to: natenbeckie (Oct 15, 2009 10:50 am) About the rotors...do you feel the need to replace all four? My issues always seem to be with the front pulsating. Can you put aftermarket (better) rotors up front and leave the GM OEM ones in the back? Thanks, Bill

| I believe we had the same problem, replacing the fronts with non-cheap rotors stopped the pulsing problem. I think due to mileage we've had them all replaced by now (at a non-GM shop) and haven't had a recurrence. | |

Replying to: spike99 (Oct 17, 2009 9:09 am) The lines are not kinked. I checked the line flow and its fine. This isn't the first one I have seen like this and my buddy's 07' Impala SS was the same way with the 4T65E-HD. This is another case of GM design and engineering being flawed. In fact, I went over the 30,000 mile fluid service interval on my IS300 (45,000) and I just did a flush on it this past weekend. The fluid was still red. Not the bright translucent red Toyota T-IV is out of the can but it was without a doubt still red. My SV6 on the other hand is showing more hues of brown than red at this point after roughly 32,000 on the fluid with the LPD on it (I installed it at the same time I did the flush). The 3.9 was a much better engine for this van all-around. I wish I had at least waited for it. Better yet, I wish I would have kept my Mazda MPV. |

I don't know how they have the brake proportioning set up on this thing, but it's heavy on the rear. This is the 2nd set of pads that were put on at the same time as the fronts (first set were the original pads) that have worn as much on the rear as the front. I thought maybe the rear calipers were sticking but they aren't. It's just how it is. |

So my ABS and TCS lights have started coming on again more and more frequently lately (nearly every time I drive it now). Tonight when I got it home I left it running in the driveway (since it clears the codes when you turn the key off - what a genius idea) and plugged in to it and got a "C0035 - LF wheel speed circuit malfunction." I did a quick Google search and up popped TSB 08-05-25-004. This TSB seems to cover every GM model made in the past 5 years from Vettes to GMC trucks to Caddys. Wonderful GM. So you have a faulty wiring setup on the ABS sensors on all of your late model cars and trucks and you don't do anything about except release a TSB. And shame on the NHTSA for not mandating a recall because the ABS system isn't considered a mandatory safety system. This issue is listed with the NHTSA BTW. Google that TSB...you'll see. Now I am going to have to spend hours of my time tracking down phantom wiring issues with a broken leg and spend money on a replacement harness more than likely. Thanks for the kick in the nards again GM!

Replying to: natenbeckie (Nov 28, 2009 9:31 pm) One of my previous GM vehicles had ABS problems. After $3,000+ in troubleshooting and wire tracing repairs, the problem still wasn't resolved. My local mechanic hinted that if ABS cannot be fixed for "reasonable" repair cost, then perhaps its fuse should be pulled. I pulled its fused (drove it like a non-ABS / non-TCS vehicle - like my many previous 60-70-early 80 vehicles) and it ran great afterwards. Actually, that GM vehicle suddenly had better brakes then its factory "electronic over loaded" braking system. Even on bad winter roads. Not suggesting you should pull its ABS fuse (liability thing) but.... Worked great for my previous GM vehicle.... BTW: Did I mention that some GM vehicles are base configuration "without" ABS system? For example, 2007 GM Saturn IONs and the 2003 Buick Rendezvous. With no-ABS in its base configuration, it makes me believe that ABS is "optional" - not mandatory in any vehicle. Something to think about as well... . |
