Ten problems related to battery have been reported for the 1999 Chevrolet Tahoe. The most recently reported issues are listed below.
Ac delco battery leakagae. Second time.
Ac delco battery leakage twice in the last two years. Both as a result of acid leak from the positive terminal.
Battery acid leaks from positive post, causing corrosion in brake line.
Problem: battery acid is leaking from the positive terminal. The acid released falls on pressurized a/c lines and the right front brake lines and fitting connecting the brake hose. This is the second battery to be replaced in my vehicle. This problem was found in when disconnecting the first battery (3/2001) for charging. Acid released from the orginal battery was contained and neutralized immediately. This second instance was not found until, acid was found on the garage floor. Extensive corrosion has occured on all metal parts below the battery. Dealers has stated this problem is prelavent in all 1999 Chevrolet with continuous head light operation. Two gm dealers have stated they are seeing leaking batteries in one or two vehicles per day. The service manager at hallowell Chevrolet in clovis, CA, stated that gm has been working on a new battery design to correct the problem for 8 to 10 months. The uncontrolled release toxic substances poses both an environmental and safety hazard. One failed battery may be an expected probability, although the prevalence of the numbers scene at two dealers and two instances in my vehicle, warrant and require governmental action and oversight. The leaking acid is affecting the integrity of the air conditioning system (not a seafety problem, ulness the escaping r-134/.
The battery positive leaked onto the brake line which in turn ate through the brake line and a loss of brake fluid and brakes without warning happened. I was traveling at 40mph when went to apply the brakes and they went slowly to the floor as I was stopping and then dropped to floor and I went thru the middle of a intersection (I thank god that traffic was light). I see that in this data base that this is common problem and I can't believe that this is not a recall. How many people have to be hurt of killed before GMC does something about this. I have purchased 8 new gm vehicles in the last 10 years and if this is the way they are going to treat customers, I will not buy another. Needless to say the vehicle will be for sale as soon as it is fixed and another brand will be considered.
Truck was taken in repeatedly for brakes, transmission, air conditioner and headlights prior to warranty expiration and was told they could not duplicate the problem or it was under "chev specs" or we were experiencing anti-lock brakes. Water pump began leaking and had to be replaced 2200 miles outside of warranty. Entire brake system, lines-calipers, everything had to be replaced because "foreign fluid corroded" the system. No one has touched the brakes but the dealer. We repeatedly complained about the brakes taking too long to stop the vehicle, having a spongy feel and absolutely no confidence that they would stop in an emergency situation. Overall, the brakes just did not feel safe and we reported this when the vehicle was still under warranty. Intake manifold is leaking and needs to be replaced. Battery exploded and leaked battery acid everywhere damaging other engine parts. Transmission is in need of an overhaul/replacement either as a direct result of the battery exploding or mere coincidence considering we have always complained that something was wrong with the transmission and you could push the truck while in park a full foot. The air conditioner has always leaked after driving approx. 2 hr as well as the driver's side high beam headlight always has water in it. Detailed complaints have been filed with the attorney generals of az and FL, as well as copies sent to the dealer, manufacturer and leasing company involved. Chevrolet should be ashamed of the shoddy product that rolled off their assembly line and the manner in which they conduct business surrounding consumer complaints generated as a direct result from poor workmanship at one of their factories. There is a long list of "cosmetic" defects as well. For instance, the custom leather seats that we paid extra for are wearing holes in them; the driver's side door handle is cracked, drink holders are rusting, and the list goes on and on.
The positive terminal on the original delco battery broke off, leaking acid down the wheel well onto the right front brake lines and the abs electrical connector to the right front brake. The acid corroded the brake line, electrical connector, and removed the paint on the frame and lower a-frame. The failure occured in our driveway and the vehicle was disabled. Had to buy a new battery and 2 cans of battery acid cleaner to remove the acid in the right side engine compartment and lower frame assembly. The brake problem occured as my wife was driving home. She said that the steering was shaking and rumbling. It was pulling to one side. I found the left front caliper had seized in the cradle assembly and worn the outer pad to less than a tenth of an inch. She said it had been squealing for a couple of days. The right side was ok, but, I changed all front pads any how. I had to clean rust from the caliper and mount to allow movement in the assembly. I still have the bad battery and the brake pads.
Battery has leaked acid onto brake line, causing all fluid to leak, amd a loss of braking power. Deaelr has been contacted. The battery acid corroded the brake line.
Battery leak. Caused positive post to corrode/disconnect. Truck is only 1 year old, with less that 15,000 miles. Battery acid all over engine and hoses.
