| My dad has a 2001 Denali and he's had only had it into the shop for recalls. We own a 2000 Tahoe LT but let me tell you the Denali is really a step and worth the money (if you can afford it). He has almost 85,000 miles!! on his Denali and let me tell you that 6.0L does what its suppose to. | |

| Would you mind sharing exactly what kinds of problems your Denali had? I own an '02 Denali and I'll admit that it has given me some problems - some I'm still trying to resolve. Thanks! | |

Has anyone ever had this come on? Just had an oil change and tire rotate and while heading home, I got this light. Could it be something they did during the tire rotate? Also, they told me I should have my FT & Rear Diff Flush, Transfer Case Flush and Trans Flush. This is 2001 Denali with 42k miles. Should these need to be done already? Thanks, Doug

Make the dealer Check the Autoride shock sensors. I'm betting they knocked one loose when they rotated the wheels. I had this happen. Light came on shortly after I left the garage and drove right back. They fiddled around for about 5 minutes determined which sensor, reseated it and not a problem since. I've got 39k on my 2001. So far my dealer hasn't suggested all those services. I don't see the manual calling for a tranny flush until 50k and it just says to check and fill as needed the diffs... I'd be skeptical of this dealer unless you drive the rig really hard. |

| Went back and they checked it out. Said it was the right front shock sensor. Told me if it came on again I needed a new shock at $450+. I sent an email to the service advisor to see why the flushes were recommended. I will let you know what he comes back with. Thanks for your input. | |
Just bought a 2003 Denali XL after trading in a 2002 Yukon. Since buying the car we have been hearing a cracking and popping noise from the car after shutting of the engine (and also while at idle). The service manager tells us this is "normal for these cars". Has anyone else experienced a problem like this?

I'd be skeptical they didn't damage the sensor when they rotated the tires... funny how it cropped up so shortly after. If you had another GM dealer in the area, I'd be tempted to see what they would say. |

| Here is what the service tech told me on the flush: It is recommended to flush the tranny every 30,000; and differentials / t-case every 30-40000. When it comes to maintance for vehicles', GM is our worst enemy, with respects to the owner's manual. GM prints the bare minimum for maint, with hopes your vehicle will wear out and you will need to replace it. As I truck owner who had to replace a front diff. to the tune of $2,000, I personally recommended every 30-40000 on those flushes. I waited until 65,000 by then the damage was done; mainly from the metal particulate that came from the break-in period when it was new. This is my first truck, so I haven't been down this road before. I guess it makes sense. | |
| I flush everything involved with lubrication (engine oil, transmission fluid, differential fluid, etc.) after the first 3,000 miles. (Do a complete fluid exchange, not just drain and refill. If a filter is involved, replace it as well.) You really do need to get rid of the metal particles that are thrown off during break-in - if not, they will come back to haunt you. | |

Our rear storage area is soaking wet after the rains here in DC. Nothing was left open, and the weatherstripping appears in tact. Would replacing the rubber and silicone to the frame be a wise idea? As a home builder, I am all for silicone for water troubled areas but am leary of doing the same to my vehicle. Yes, I checked the rear AC. I have kept the back trim panels out for a month. IMO I think its the rubber gasket. Any suggestions or cautions? |
