 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. *ak

 Our ase mechanic states they have replaced ~35-40 similar chev suburban radiator failures in past 24 months in their shop (documentation on request). these have been associated with water pump failures, intake manifold leaks and occ. head gasket failures when coolant has leaked over engine. among ase mechanics in our area this is a well-know, lemon design failure which will cost me $900 to repair. *ak

 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 rear differential had the seal replaced 2 or 3 times but it still leaks. the fuel pumped failed on our car leaving us stranded. we were told that the truck needs to keep a 1/4 tank of gas at all times in the tank so that this does not happen. the air conditioner has never really worked well on this model, it appears that it is undersized to handle the thermal load. we also had to have the spot welds on the door jams filed because many sharp burrs existed which were a safety hazard.*ak

 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. could not or would not fix the problem. i have replaced fuel injection pump 2 times minimum, have replaced pmd/fsd at least 5 times, replaced auxiliary/lift pump two times, have drained and cleaned fuel tank 2 times. most recent injection pump replacement was in aug/september 05 (7000 miles ago). i have spent at least $5000 trying to fix this problem. engine stopped last monday and will not restart. am surprised no complaint has been filed before now.*jb
 Consumer states that while driving at any rate of speed the vehicle will intermittently cut out or stall surge forward and then returns to normal speed. dealer states that this occurs due the diesel injector pump. please give any further details
ENGINE AND ENGINE COOLING - ENGINE - GASOLINE
09/03/2000209/01/2000
 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). *ak

 In february my car died while leaving a parking lot. i turned out to be acid corrosion on the battery. i have already had to have my positive battery cable replaced under extended warranty due to acid corrosion. even after cleaning the acid off i am still having problems and will have to replace the battery even though it says it is still good. i know of another suburban (95) also having the same problem.
 Engine cuts off without warning, causing all power steering and electrical power to go out. also. dealer has seen vehicle 5 times, and has changed fuel pump numerous times. but problem still exists. *ak
