Problems with anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The key and ignition lock cylinder should be replaced to correct this condition.

1999 Cadillac Eldorado Problems
The trunk pull down switch may fail causing the trunk lid not to close completely. Our technicians tell us that the failed switch can be replaced without changing the complete pull down motor assembly.
The air conditioning system can be prone to refrigerant leaks and failure of one or more pressure sensors. The AC pressure sensors should be checked for proper operation when ever the AC system is serviced.
The engine may develop an oil leak from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.
Power seat motors and seat position sensors may fail causing the power seats to act erratically.

1999 Cadillac Eldorado Reviews
brake lights work n back window but no were else
I was surprised to see there were never any recalls on this car. Almost every review online has an engine oil leak, security system failure of some sort, seat malfunction of some sort and the soft close trunk breaks. Other than that, a solid, strong car, great in the snow, amazing pickup and just looks like a sharp Caddy. Has its problems but I wouldn't trade it.
1999 Cadillac Eldorado ETC, with 52000 mile,has a loud knocking in the lifters at start up then slowly goes away as it warms up, with the low miles makes me wonder! anybody else having this problem? also the oil level seems to be all over the place, check prior to start it's fine, short drive, let it sit then it's down over half, then re check after short drive, it shows over full? I have worked on my own vehicles for 30 years never seen anything like this...
