Radio and power locks would stop working will driving. Car battery completely died overnight. Jumped and took to technician. I mentioned checking the cables. They installed new battery today and tonight same problem. Radio turned off, power locks not working and ABS, Battery lights came on. Gas and odometer not registering on info display all though info display did not lose power

my problem is door are locking in unlocking and some dash light blinking on in off in truck trying to cut off

Put in a new battery June 30. Drove to Nashville and back. Parked car in garage. One week later, no battery. Completely dead. Put in new battery. Overnight the battery was dead but would take a charge. Battery won't stay up. Can't find short.

My car will go months being fine and then will all of a sudden start pumping the brakes by itself, lights flashing, bells ringing, doors locking, transmission switching gears by itself, we have replaced so many battery related cables and batteries, I am so frustrated.

Loss of all electical power to vehicle as though battery failure. After checking battery connections by simiple movement of the cable at the battery, power would restore. after several attemps to pinpoint the power loss( clean and tighten cablels)was able to verify negative cable as the problem. The crimped conection at the battery end is loosing contact. I re-crimped the end and the problem ended for about a month. It started doing the same and by lifting the negative cable slightly the power comes back on. I am replacing the whole cable this time.

Driving along, and lights on dash flicker, engine races, transmission free-wheels out of gear, radio loses signal, door locks go crazy locking, then unlocking. Shut down vehicle and no electric of any kind. Wait awhile, and full power is restored. Took to dealer, charged me $250.00 to replace battery ( I didn't think that this was the problem.) Next day, driving and same problems start happening again. I lifted the negative cable a bit, seemed to restore lost power. Will investigate further.

I had the same erratic electrical problem where all power would be lost, door locks would lock and unlock, radio would go on and off etc. After several trips to the normal place I have my car repaired I began to play with the ground cable. It turned out the cable was frayed on the end that is attached to the engine block, not at the battery. Replaced the cable and it has been fine since. Knock on wood!

All of a sudden stuck in first gear...then dashboard lights flicker on /off seat belt dinger goes off door locks up and down. Next engine wont crank

I purchase a 07 Escalade for 69,000 original miles Everything was fine for a while until one day I stuck my key into the ignition and my car did not start I got the car towed to my mechanic to test the batterythe battery was goodhe tested negative and negative was no good he changed the negative wire to the battery and all was good for now . .......

I have had the same problem, replaced the cable, ran fine but now the problem is back.

Four weeks after purchasing this vehicle (used) I took it to the car wash and parked it in the garage over night. Next morning...key fob wouldn't open door, so used key to gain entry. Inserted key and...nothing. Took out my handy multimeter and discovered the Negative terminal had some problems. Used pliers until I bout some crimps and everything was fine.

Cleaned cabled and re-tightened, but problem is back sporadically. Glad to see the fix is relatively simple and not a deeper rooted electrical gremlin. I was concerned it would be worse. Thanks for sharing info!

Electricals seem to go crazy, digital clock, outside temp, transmission shiftng, ac temp control, etc

Escalade would not open with key fob for several tries, then would open and I could start it but the head lights and door locks would keep flashing and unlocking while I was driving, but would stop after 5-10mins. But after turning engine off problem would start all over again. Finally the battery died and would not start. I checked the negative battery cable and the crimped end on engine block was loose, re-crimped and doors and lights all work fine but now I need to charge battery or get new one. Thanks for the info on cables, saved me a trip to the dealer!

Replaced all door actuators last year. New battery in 2015.

Last week, the "Passenger Door Open" warning light came up, then the interior lights came on and if pressing the door lock button, the interior lights dimmed and warning light turned off.

However, the next day, the 'Slade was dead in driveway.

My Cadillac Escalades ignition does not work, loses power, no acceleration, instrumentation panel indicators light up irraticall; vehicle shuts down in traffic intermittently. Purchased and added a new ground cable; checked/cleaned the 740 amp fuse (checked good). Caddies drives good for a while, then shut down intermittently again. After the vehicle sits for a while, it usually start and drives pretty good.

same issue as previous posts. Cadillac dealer said right out that the negative battery cable is the problem. Haven't changed it yet (they wanted $300). Looking for a cheaper solution.

During driving the truck would loose electrical power and start to coast w/o power, the door locks would open and close rapidly, the truck would go to neutral, the trans would shift down soft and sometimes vary hard at about 30 mph, the dash would loose any feature that was on, especially the auto function for climate control.

It went into this elect. fault about 2 months ago while driving in Manual mode. It now has progressively gotten worse. The other day it faulted 4 times in less than 15 min.
The truck now is not reliable to drive until it's fixed!!!!
There's seems to be very poor and cheap in quality/integrity with this vehicle to allow this to happen! I'm now scares me to own a GM / Cadillac. Even after this fault is fixed = I worried about the collateral damage to the trans from hard shifting, and other components which may have been damaged!

Vehicle stalls periodically but need to be jumped. Has new alternator.
