Engine stops running with no warning. This can occur while idling, accelerating, cruise speed, any time of year, any weather condition. Sometimes it will restart by shifting to n and re-cycling ignition switch without having to stop or leave road. Sometimes, as is the present case, it will not restart. I have owned this vehicle since new. This has been an ongoing problem beginning at 80,000 mi. Manufacturer extended warranty to 120,000 miles, has continued beyond warranty period and is a source of safety concern. This has occurred on interstate highways, in the middle of busy (high speed intersections). Dealer performed numerous attempts to fix problem, but they continued. I have had this vehicle to the dealer more times than I can count. I have had assistance from other professional sources (after the warranty period was over and was convinced that dealer/mfg. …
I have owned 2 1996-1997 Chevrolet Suburban and have had the intake manifold leak on both at about 85000 miles. I did a little local research and found that this is a very common problem for the Vortec 5.7 engine. When I called the dealership about a coolant leak from the engine area, the service writer said this was most likely the intake manifold because they get that all the time. Toay, I noticed a coolant puddle in my drive way and upon looking into it, my latest 1996 Suburban with a Vortec 5.7 is leaking at the intake manifold. This is a costly problem to the consumer. It costs approximately $500.00 to have this done. I now must make the decission to have it fixed at the dealer for $500 or to do it myself for about $150.00 and a day of headaches.
Latent defects and the GMC Suburban. The consumer has experienced several problems with vehicle. The front output shaft seals had to be replaced, the intake manifold gasket had to be replaced, and the ac heater knob had to be replaced. When the dealer was notified they fail to fix problems and he consumer had to pay at there own expense. Please respond promptly in helping to resolve matter.
I have replaced the intake manifold gasket twice now for my 1996 Chevrolet Suburban. Both times it has cost me over $650.00. Both mechanics told me that they see these at least twice a week on the 5.7 engines. They knew exactly what was wrong. They actually laughed when I asked them if it was set up as a recall item for this engine.
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. …
While driving at various speeds on the highway, vehicle would shut off or stall out without warning. When trying to pass trucks or vehicles, vehicle stalled. Was nearly run over by 18-wheeler. When it happened, vehicle has been towed to dealership numerous times. Mechanic replaced the driver (5), injector pump(4), lifter pump(2), main brain(5) & the receiver sensors(5). The computer system would sometimes allow vehicle to restart. Problem is not getting better. Vehicle was bought new. Owner very upset. Dealership working with owner.
