    New owner of a 2002 Deville.. Problems already

    Hello everyone.. Just picked up a new to me 2002 Deville (base)with 101k miles. So far the car has been great.. I have been part of a volvo community for a while and my other car is a 2004 Volvo S60R. This is my first Cadillac and first V8. But I have been having a few issues that I need help with.

    1. The fuel gauge is being buggy. Sometimes it reads perfectly fine. And sometimes the gauge will bounce between full and low. Any ideas?

    2. There is a noise coming from the front drivers side. It sounds like a card on the spokes of a bicycle. Initially it was diagnosed as cupped or chopped tires... But I still didn't think that was the case. The car was put up on lifts and put in drive. The drivers side wheel does not engage. The noise is coming from the transmission. I'm not getting any lights on the dash.

    3. There is some kind of loud electric motor sound coming from the back.. I'm assuming it's for the leveling suspension in the back.. But is it supposed to be very loud? And how often is it supposed to come on when driving?

    4. Brakes seem to be on the soft side. They put in brand new pads.. But I read somewhere that there is a heavy duty brake system offered for the deville. Can I upgrade to that so I can get more performance from the brakes?

    These are the only issues I seem to be having at the moment and I hope they are easy to fix. Thanks for any help in advance.

    Probably need to change the fuel level sensor. There is an access panel in the trunk so there is no need to drop the tank.


    2. There is a noise coming from the front drivers side. It sounds like a card on the spokes of a bicycle. Initially it was diagnosed as cupped or chopped tires... But I still didn't think that was the case. The car was put up on lifts and put in drive. The drivers side wheel does not engage. The noise is coming from the transmission. I'm not getting any lights on the dash.
    When both wheels are off the ground and the car is in gear, only one wheel will spin. That's normal. Can your hear the noise when you spin the tire by hand? At what speed does it start to make noise when driving? Ripped CV joint boot perhaps?


    3. There is some kind of loud electric motor sound coming from the back.. I'm assuming it's for the leveling suspension in the back.. But is it supposed to be very loud? And how often is it supposed to come on when driving?
    Yes, the ELC compressor. It should be a low groan type of sound, but should not be REAL loud. It should only come on once at start up and then only to level the car when and if needed. If it runs often, there is probably a leak in the lines or the shock boot. Spray the lines, connections and boots with soapy water when it is running. A leak will foam.


    4. Brakes seem to be on the soft side. They put in brand new pads.. But I read somewhere that there is a heavy duty brake system offered for the deville. Can I upgrade to that so I can get more performance from the brakes?
    HD brakes are for limos. If your brake pedal is soft, the brakes may need to be bled.

    I thought the traction control would kick in and send power to the other wheel? The noise sounds like its coming from inside of the trans. I can't hear the noise when I the wheel is spun by hand.. maybe because I'm not spinning it fast enough... But when I am driving.. It starts coming on at about 25mph.

    Will try this out this weekend. Not sure what is often.. but lets say on a 50 mile trip.. it comes on at least 5 times... with just me in the car.

    Brake pedal is hard.. But braking distance is long... Maybe this is due to cheap pads? Rotors look original though.... I will try to bleed the brakes when I can.

    If the noise starts at 25 MPH I wouldn't think it was wheel or tire related, but stranger things have happened.

    I assume you have checked the trans fluid (engine idling at operating temperature)?

    The ELC running 5 times in a 50 mile trip with no weight being added points to a leak in the system someplace.

    Cheap pads, glazed rotors,

    Do you have solid or cross drilled rotors? I put Brembo cross drilled on mine, and I have a tick. If anybody jumps in on this one, yes I 100% know it's from my rotors.

    Firestone told me the noise is coming from within the trans. They said it sounds like the traction control is trying to engage buy can't.. which is maybe what is causing the noise. That is all they know.

    Also, talked to my dealer earlier. The Day I picked up the car from the dealer, they finished replacing a "Torque converter clutch solenoid." It was causing the CEL to come on. Trans fluid was just replaced. All pads are brand new.. Rotors are just regular non slotted or drilled rotors.

    Either you misunderstood what you were 'told', or no one at that tire dealer's operation knows the first thing about front wheel drive Cadillac traction control. Your transmission has nothing to do with traction control.

    They also noted it in the paperwork that I got...
