On the electrical, I refer to my air conditioning and heater. When I have my air selection to coldest and I drop 1 click for it to be less cool, my heater turns on and at times it smells like something burning. I have to turn it off . On the engine, after I hit 90,000 miles, I have to fill up my engine oil every 2-3 weeks because my vehicle is burning it quick or something. It doesn't leak oil at all. The oil just seems like it's burning somewhere and I ha e to be waisting money to buy oil $30 to $60 a month. Please help. Thank you!

GM IS RECALLING CERTAIN MODEL YEAR 2006 THROUGH 2010 HUMMER H3 VEHICLES.

Remedy: DEALERS WILL APPLY AN ADHESIVE TO THE HOOD LOUVER TO SECURE IT TO THE HOOD. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON APRIL 12, 2010. OWNERS MAY CONTACT HUMMER AT 800-732-5493 OR AT THE OWNER CENTER AT WWW.GMOWNERCENTER.COM.
06V417000 · Air Bags:frontal
Oct 31, 2006
CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.
Consequence & remedy
Consequence: IF THE PASSENGER SENSING SYSTEM MALFUNCTIONS, THE FRONT AIR BAG ON THE PASSENGER SIDE MAY BE DISABLED WHEN IT SHOULD BE ENABLED, OR ENABLED WHEN IT SHOULD BE DISABLED. IN EITHER CASE, IN THE EVENT OF A CRASH THAT REQUIRES AIR BAG DEPLOYMENT, A FRONT PASSENGER'S LEVEL OF INJURY MAY BE INCREASED.
Remedy: BECAUSE A REPLACEMENT LEATHER SEAT COVER THAT IS COMPATIBLE WITH THE PASSENGER SENSING SYSTEM IS NOT AVAILABLE, GENERAL MOTORS (GM) WILL REPURCHASE THESE VEHICLES IN ACCORDANCE WITH THE TERMS STATED IN GM'S LETTER TO OWNERS. THE RECALL BEGAN ON NOVEMBER 6, 2006. OWNERS SHOULD CONTACT GM AT 1-877-477-1022 TO BEGIN THE PROCESS OF REPURCHASING THEIR VEHICLE.
