This shut off happens because a sensor is sending a signal to the computer telling it to do so because there is a severe problem. Cadillacs are notorious for coolant issues. Take it to a mechanic who can check and reset your codes, he may also tell you what the problem is. Good luck.

What wrong when the battery light come on and stay on then keep driving and the car radio blink and the car cut off


Sounds like your battery died due to your alternator failing. The battery light most likely came on when the Alternator wasn't giving enough juice to keep the battery charged. Once the battery drained, your radio cut off and then your ignition.

I own a 2001 Cadillac DHS. The "SERVICE ENGINE


p0071 is the ambient temp sensor which is located by the hood latch behind the grill. They have the yendency just to go bad and you can replace the part for about 30.00 dollars. The dealer is usually higher than a transmission shop. It requires removing the engine and transmission at the same time which means removing the complete frame. A smaller shop may be able to beat the price if you can find one that works on caddies. Some will and some won't. I would shop around.

My 92 Caddy Deville has reverse lights that stay on while I'm driving, how do I get them to turn off?


Hello: The back up lights get 12volts through the neutral safety switch. This is mounted on the top of the transmission on the drivers side. The switch could be out of adjustment and or failed or the wiring could be bad. To check te wiring disconnect both connectors on the switch, turn key on engine off apply park brake put transmission in drive and check to see if the reverse lights are on.
