1996 Chevrolet Suburban electrical problems

ELECTRICAL SYSTEM:12V/24V/48V BATTERY

THE BATTERY CABLES LEAK ACID, . WHEN THE BATTERY BECOMES CORRODED, THERE IS NO POWER TO THE VEHICLE. THE DEALER HAS TOLD ME THAT THE BATTERY CABLES ARE BAD, WHICH WE HAVE REPLACED, AND THE PROBLEM CONTINUES. WE HAVE HAD THE BATTERIES (REPLACED MORE THAN ONE) CHECKED, AND THEY ARE FINE. WE HAVE HAD THE POSTS REPLACED, AND THE PROBLEM GETS WORSE. THE LATEST, (IM STRANDED RIGHT NOW) SEEMS TO BE THE WORST YET. AT FIRST WHEN THIS STARTED HAPPENING, IT WAS A COUPLE OF MONTHS APART, NOW ITS EVERY WEEK. ALSO WHEN IT STARTED THE CABLES WHERE REALLY CORRODED BEFORE THE ENGINE QUIT. NOW THEY CAN BE WIPED OFF WITH A DRY TOWEL. ALSO, THE A/C HAS STOPPED WORKING DUE TO CRACKS IN HOSES. (FROM THE ACID) BEING AS I LIVE IN TEXAS, EVEN IF THE TRUCK IS RUNNING I CANT DRIVE IT IN THE SUMMER, EVEN IF WE FIX THE HOSES IT HAPPENS AGAIN. WHEN I HAD THE VEHICLE TOWED TO THE DEALER THE LAST TIME, THEY TOLD ME THE BATTERY WAS FINE, BUT I NEEDED TO SPEND 400.00 TO HAVE THE CABLES REPLACED AGAIN. HOW IS THIS PROBLEM REALLY CORRECTED. TALKING TO OTHER PEOPLE WHO HAD SUBURBANS I HAVE FOUND THAT A NUMBER OF THEM HAVE HAD VEHICLE FIRES DUE TO THE ACID PROBLEM!!! HAVING CHILDREN IN THE CAR, IM TERRIFIED TO DRIVE MY TRUCK. (WHEN IT EVEN STARTS) I CANNOT SELL IT TO SOMEONE ELSE AND PUT THEM IN DANGER. THE FUEL PUMP HAS FAILED. WE WERE TOLD THAT WE HAVE TO KEEP A 1/4 TANK OF GAS IN THE TRUCK. WELL IT IS GOING OUT AGAIN AND I KEEP IT FULL! ALSO, SOMETHING TO DO W/ THE ABS BOOSTER BEING BAD. WELL MY BRAKES ARE FAILING AGAIN. (LESS THAN A YEAR LATER) THE PADS ARE FINE. THE ACID LEAKING HAS CAUSED DAMAGE TO OUR DRIVEWAYS, NOT TO MENTION THE KIDS AND ANIMALS IN THE NEIGHBORHOOD GETTING INTO THE ACID ON THE GROUND. PLEASE SEND ME ANY INFO THAT MIGHT HELP ME. IM AM GOING TO CONTACT THE DEALER AND TALK TO THEM AGAIN ABOUT THE INFORMATION THE I HAVE FOUND, RE: IM NOT THE ONLY ONE THIS IS HAPPENING TO.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY:CABLES

BATTERY LEAKS AND SUBSEQUENT POSITIVE CONNECTOR/CABLES ROTTENING FROM ACID PREVENT CURRENT FLOW TO THE STARTER AND TO THE COMPUTER - SO THAT THE ENGINE WILL NOT START. IT IS NECESSARY TO LOOSEN THE BATTERY CABLES, AND CLEAN SOAK THEM IN A MIXTURE OF SODA AND WATER, THEN REHOOK! MY WIFE CAN NO LONGER USE THE CAR, BECAUSE SHE IS UNABLE MAKE REPAIRS OF THIS NATURE, IN THE VERY GOOD LIKELIHOOD THAT THE FAILURE TO CRANK WILL OCCUR WHEN SHE IS DRIVING. I HAVE PREVIOUSLY REPORTED THIS, BUT DID NOT REPORT THAT I HAVE JUST DISCOVERED THAT BATTERY ACID LEAKS HAVE CAUSED SEVERE RUSTING OF THE RIGHT FRONT BRAKE TUBING DIRECTLY UNDER THE BATTERY CONNECTIONS. THIS PRESENTS A POTENTIALLY SERIOUS SAFETY MATTER. FYI, THE CAR NOW HAS HAD 3 DELCO 78 SERIES BATTERY IN IT - FIRST TWO REPLACED BECAUSE OF LEAKING!! , AND NOW THE NEW 3RD ONE IS LEAKING.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY

THE INITIAL SYMPTOM HAS BEEN UPON STARTING THE ENGINE THE CLOCK RESETS TO 1:00 AND THE AIR CONDITIONER LIGHTS GLOW ON AND OFF(BUT THE A/C SWITCH IS OFF). THE NEXT SYMTOM IS WHILE DRIVING THE ENGINE WILL JUST DIE UNEXPECTEDLY. THE SUBURBAN HAS BEEN TAKEN TO SEVERAL DEALERS. THE BATTERY HAS BEEN REPLACED 4 TIMES SINCE THE VEHICLE WAS PURCHASED IN MID-1996. THE BATTERY HAS LEAKED SO BADLY THAT PARTS UNDER THE AREA WHERE THE BATTERY SITS HAD TO BE REPLACED. BESIDES WHAT SEEMS TO BE ELECTRICAL PROBLEMS, THE BRAKES IN THE FRONT HAVE ALREADY BEEN REPLACED 4 TIMES. THIS LAST TIME THE ROTERS WERE REPLACED BECAUSE THE DEALER SAID THEY WERE OUT OF MFG. SPECIFICATIONS. BRAKES AND BATTERY REPAIR ARE NOT UNDER EXTENDED WARRANTY. EACH TRIP TO THE DEALER IS MORE $500.00. THE POTENTIAL FOR A LIFE ENDING ACCIDENT IS SO GREAT WHEN THESE SYSTEMS FAIL ON A VEHICLE. WHY AREN'T THESE VEHICLES BUILT WITH BETTER RELIABILITY? THE TRUCK WAS PICKED UP FROM THE DEALER ON 9/11/2000. THE ELECTRICAL PROBLEMS ARE STILL NOT FIXED! (DESCRIPTION OF VEHICLE: CHEVROLET SUBURBAN, V8 VORTEC 454, 4X4, 3/4 TON).

ELECTRICAL SYSTEM:STARTER ASSEMBLY

FIRST TIME AT 30,000 MILES, SYMPTOMS APPEARED TO BE DEFECTIVE STARTER OR STARTED SOLENOID- FOUND THAT THE BATTERY WAS LEAKING AT THE POSITIVE TERMINAL AND CORRODED/RUINED CABLE CONNECTING TO BATTERY. DEALER IN NORTH CAROLINA [PARKS CHEVROLET, CHARLOTTE REPLACE BATTERY AND CABLES, FREE]. SECOND TIME, AT 50,000 MILES, I CHECKED BATTERY AND FOUND LEAKING AGAIN - SOAKED CABLE CONNECTIONS IN BAKING SODA WATER SOLUTION AND RE-INSTALLED WITH NEW BOLT. SINCE THAT TIME, I HAVE CLEANED THE CABLE CONNECTION AT BATTERY POSITIVE POST WITH SODA/WATER SOLUTION AT APPROXIMNATELY 10,000 MILE INTERVALS. FROM TALKING TO OTHER OWNERS, IT APPEARS THAT THE BATTERIES ARE THE PROBLEM - LEAKING AT THE POSITIVE BOLT/TERMINAL CONNECTION. AS A FORMER MECHANIC AND FACTORY SERVICE REP, I HAVE BEEN ABLE TO AVOID A SERIOUS THREAT TO SAFETY BY FREQUENT INSPECTION AND MAINTENANCE, BUT THIS IS REALLY A DANGEROUS SITUATION AND MAY HAVE FRIGHTENING RESULTS UNLESS SOME ACTION IS TAKEN TO CORRECT
