Replying to: marvag (Jul 28, 2009 10:47 am) Hello Marvaq -   I too have a 2004 Suburban LT w/Autoride. I currently have 105,000 miles on it. It has been as trouble free as any import that I have owned. If I would have read these message boards when I was looking I would not have purchased one - But I'm glad I did. I've changed the oil every 3K - not whating for the change oil light to appear. I replaced (GM extended warrenty) a switch 15K because the service 4wd light appeared. Front axle seals 47K (GM extended warrenty), Water pump 58K (GM extended warrenty) and a Battery 68K. I've changed the transmission fluid (Not Flush) 50K and changed the engine coolant when the water pump was changed. The brakes are just starting to make noise, so it's time for pads and maybe rotors.   The only other issue that I've had was gas mileage. I was getting 17-19 mpg until about 17K, then it went to 14-15 mpg. Because no check engine light, dealer was clueless and useless. Around 70K, it when to 12-13 mpg. Dealer still no help. I've been reading on the boards that the intake is probably leaking and perhaps a loose wire on the MAP sensor. So - before the summer is over, I'll tune her up, change the wires, re-torque the intake and check the wires on the MAP sensor.   The truck is used for soft off-roading (Camping, Fishing), some towing (Flat bed trailer w/car attached), daily commuter / road trip vacations.   Very pleased with the truck - Just hope when I get ready to trade her in - hopefully 200K, that GM will (1) Still be in business and (2) still making BOF trucks.

We have a 02 Tahoe that I bought in 04, taken it to Israel, back to Texas, to The Netherlands and now back to here in Wash, DC. Mileage is almost at 90k and it runs great.   Besides normal oil changes, I've replaced the intermediate steering shaft (that was driving me crazy in Israel when turning), replaced the brake pads/all discs and rear calipers (which both locked down on the discs destroying the discs). We have replaced the tires twice (once from the dry walls cracking), replaced the plugs with iridium's at 80k along with new GM spark wires as the others ones were getting brittle. We have no/zero faults on the sensors and love the truck except one thing - the gas mileage has been getting worse and worse.   When we first bought the Hoe we were able to getting about 18-20 mpg on the freeway and 15 mpg in the city (300-400 per tank). Now it is lucky to get 15 mpg on the freeway and 11 in the city (250-300 per tank).   I've researched this topic here on Edmunds and on the web, found a few suggestions and recommendation but is there any one specific problem out there which has been identified? Seems I've done everything except changing out the 02 sensors. Any ideas and suggestions out there?   John
#4 of 8 04 Suburban interior lights come on when driving, locking/unlocking by 4grlzma Oct 18, 2009 (3:04 pm)
I have an 04 Suburban and while driving today, the interior lights came on, the doors were unlocking and locking and "Driver Door Ajar" displayed on the dash. I stopped to check the doors.. all closed.. the lights stay on the whole time while driving and do not go off when ignition is off. Had to disconnect battery for them to go off. Any help greatly appreciated! Replies to this message: kiawah (Oct 18, 2009 3:07 pm) 4grlzma (Oct 18, 2009 3:13 pm) kiawah (Oct 18, 2009 4:19 pm)

Replying to: 4grlzma (Oct 18, 2009 3:04 pm) Check that the drivers door switch is working correctly, would be the obvious first step Replies to this message: 4grlzma (Oct 18, 2009 3:13 pm) kiawah (Oct 18, 2009 4:19 pm)

Replying to: 4grlzma (Oct 18, 2009 3:13 pm) The interior (and exterior) lights are controlled by a computer called the BCM - Body Control Module. The door switches, instead of directly turning a light on in days of old, now just send a signal to the BCM. The BCM just uses that door switch as 'one' of it's inputs, in determining what interior and/or exterior lights to turn on.   If you have metered out the door switch and find it to be working correctly (that is the recommended first step in shooting this problem), then the problem would lie either within the BCM itself, or in one of it's other inputs. (You checked for corrosion in the switch connector, right?)   The only way to troubleshoot further, is via a BCM scan tool which the dealership has. The scan tool can check that all of the switches are working correctly, and that the BCM is responding correctly to those inputs.   Just thought of one other thing.....make sure your battery is fully charged and has no corrosion on it. You should be sitting a little less than 14volts. With an '04 if that is the original battery, you are way overdue to replace it.
