    We can't get the heat to work right. Even after the car has been running for hours the heater blows cold air even when driving. The temp Gage drops and goes back up when driving the car.

    I have a 2002 Buick Renzdevous for the past 3 weeks it has been misfiring, jerking etc like it has bad gas.
    We ran the bad gas out, replaced it with new and replaced the fuel filter. It will crank no problem and sometimes I can go 3-4 days with no problems. But other days it will start jerking, misfiring, and sometimes will go dead on me. But it will crank right back or ...

    What causes stalling in idle or not turning back on when turned off?
    sometimes when slowing or in idle, lights/power dim and car stalls. At times car wont start, but battery/power works normal. When turning the key, fan and lights come on but that is it. No sounds, either.

      Check the coolant level, as the coolant heats up, the sensor is turn off.

      If the coolant is low...
      Perform a cooling system / radiator pressure test when the engine is cold - as a first step to locate the leak.
      Obtain a loaner tool / free radiator pressure tester from the local auto parts stores such as Autozone, O'Reilly, NAPA, Advance Auto, or PepBoys. Follow their instructions and pump it to an adequate air pressure 12 -15 psi or the pressure rating listed on the radiator or reservoir cap. Observe the leaks and perform the repair.
      Note: do not over pressurize beyond the pressure allowed by the radiator cap, then test the radiator cap as well.

      There may be a sensor located in the overflow bottle of your vehicle. If there is, the "cold" fill level may be below what it should be. When your car coolant heats up, it also expands, forcing some coolant into the bottle and pushing the sensor upwards, thus turning the light off.

    My 2007 Buick rendezvous sometimes will start and sometimes it won't. Also, it sometimes stalls without warning.
    Reduced engine power message appears. It is not all of the time. Has there been a recall for this model for this problem?

      The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.
