Selected complaints filed with NHTSA by 1996 Chevrolet Suburban owners, lightly cleaned up (personal details are redacted by NHTSA).
Driving from work-snowy/icy conditions. Smelled a strange odor in vehicle going from I-270s to I-370w ~ 1/4 mile from ramp. Traffic moderate. Traveling 45 MPH I tapped brakes, they went all way to floor. Turned off electrical equipment. Used engine braking selecting 3-2-1 to slow vehicle. Vehicle slowed, applied emergency brake - drove to brake down lane. Vehicle stopped-white smoke coming around edges of hood. Lower portion of windshield had couple of heat discoloration marks about 1/4 size of a penny in the middle lower portion. Air bag light came on. Dash did not feel hot, nor the instrument panel - no smoke inside vehicle. Hood would not open by hood release. Power windows worked. Egressed vehicle and driver sdie air bag inflated. Called 911 awaited fire/polcie dept. Opened driver's and passenger doors. Flames coming from steering column where it enters fire wall. …
Upon exiting freeway I noticed a burning odor. Parked the surburban and lifted the hood and discovered the left front area of engine on fire. I extinguished the flame and the resulting damage exhibited spark plug wires 1 and 3 totally burnt to ash. Wire harness to air conditioning and engine temperature sensor insulation was burnt away. Oil filler neck is completly melted away as are the sparkplug wire mounting brackets. Plastic vaccuum hose for emmission device was also melted in half. Upper radiator hose is badly burnt. Suspect electrical wire harness problem with vehicle since the battery split open 1 year prior spilling acid all over brake lines and air conditioner plumbing.
Drove vehicle & made a stop. Returned to vehicle with children & started vehicle. Noticed smoke coming from under the hood. Retrieved children out of vehicle & left. Vehicle exploded. Fire dept. Arrived to put flames out. Gave no indication of cause of fire.
Fan switch located on the dashboard that controlled the air ventilation melted the wiring harness. Dealership replaced the switch and the wiring harness twice. Dealership indicated that this was a high demand part.
The battery leaked/sprayed acid onto the engine and right front side components of the Suburban. The air bag sensor had to be replaced, but the rest of the components were just cleaned off (this included brake hydraulic cables and lines, brakes, air conditioning hoses, radiator, etc.). The dealer/manufacturer said they don't cover the battery because it is not made by them althought I think the company is owned by them. We had to buy a new battery and pay for all the damage to the car and still don't know what the long term affects of this corrosive acid will be. It left a huge orange puddle in our garage floor which we can't get rid of. We took video and pictures of the damage to the car, battery and garage. The cracked front transaxle casing was only diagnosed after they had replaced the seal on the front axle twice since it was always leaking fluid. …
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. …
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. …
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.

Battery failure resulting in positive terminal pulling out of battery and acid spilling on air conditioning and brake lines. Replaced batery and connections came loose and truck shutdown completely. This has happened on three occasions. The terminals have been cleaned each time and truck will run fine. Initial failure resulted in batery acid spilling on inner fender and brake lines. Problem was found before acid ate through brake lines and air conditioning lines. During other failures battery terminal has not pulled out of baterry but positive terminals have had corrosive build up causing truck to shut down completly. After pulling connections loose and cleaning then truck functions fine for a few months then it will happen again. This poses a seriuos condition due to lack of warning .
Problem: engine shuts off at any speed. Will restart. After numerous visits to dealer between April 99 and jan 2000 and fuel pump replaced 3 times and problem continued. Problem would occur on interstate at high speed, or in the middle of an intersection during acceleration, or while idling. Loss of control a problem on winding roads or while engaging an intersection. Dealer finally replaced ECM (computer) in jan/feb 2000 after a letter to dealership problem corrected. Mfg. Extended warranty to 120,000 mi. Engine shut off and would not restart in March 2002 rear transfer pump replaced. In nov. 2002, engine has begun to shut off again (at least 5 times) since 11/20. I anticipate a large bill from dealer to correct a recurring problem. Will take to dealer this week (12/2/2002). Dt
