    I have starting problems. I have only 34000 miles on it. I live in
    Minnesota and it is getting in the 30's at night now. But the problem
    seems to happen anytime below 40 degrees. I get out in the morning and it
    turns over and just about starts and then I sometimes step on the gas and
    let off and then it won't start. Sometimes it does not turn over at all
    even with the clutch in. Since the warranty is off I have taken it to my
    mechanic and not a Saturn dealer because I don't trust them. The mechanic
    had it all day and can't find the problem. Please help!!! Thanks, Bill

    If the problem is temperature-related, the mechanic is never going to find it
    if he keeps the car all day in a heated garage. Have him keep it overnight
    either outdoors or in an unheated building, and check it in the morning when
    it's cold.

    The only time you take your car to dealer is when you have engine
    driveability problem. This is the case. I know Saturn Ion has the
    anti-theft sensor built in the ignition switch. When the ignition key
    is turning the sensor inside the ignition switch (passlock switch) read
    the reistance and send to the Body Control Module (BCM) and allow fuel
    for starting. If not reading the correct resistance it will cut fuel
    and enter security tamper mode by not injecting any fuel. When this
    happens and secuurity lock is display on the instrument panel cluster.
    The resistance in the ignition switch sometimes change slightly at
    lower ambient temperature. I think this is what you are experiencing.
    This problem can only be correct by replace the defective passlock
    switch and program the BCM by the dealer.

  4. I have a 2003 QC. There is a known problem with these symptoms- cause is
    bad lubricant used in the ignition switch. I had mine replaced by the
    dealer. All is well now. I thought yours would be in warranty until 36,000
