 My wife was in danger driving the truck when she brought it to another route (another shop), which was hutchens chevrolet. they told my wife and gave her the paper work stating that, the truck was unsafe and she could have been in danger if continued driving it. when he was told of the brake problems, (the car dealership owner) he instructed my wife to take it to his own auto repair shop, when my wife got the truck back, it was in the same state not everything was fixed. the work was completed at hutchens. the work had to have cost about $378.00. and there are more troubles with the truck, i see signs of rust and corrosion, there are vibrations when the vehicle is in excess of 60 miles.

 My wife and i have had to make major repairs to our 1998 blazer. we had to replace the water pump ($294.55) in october 2002. then, the transmission started slipping and got worse. we took it to aamco, where we were informed that it had to be rebuilt. this was in july of 2002. the total cost was ($2077.37). i inquired that same month at chevrolet about recalls, and they said that there were none. since then, we have had numerous minor problems with the lame suv, including broken recliner handles, steering that pulls and grinds, and a malfunctioning electrical system (clicking sounds from under the glove box, three batteries replaced). i saw a report last week about the use of dexcool and its possible link to problems in gm vehicles. are there any remedies available at this time? *ak

 My 1998 chevrolet blazer has had regular problems with the cooling system not providing heat to the passenger compartment even though the engine is running at proper temp. the heater core is continually clogging up requiring regular trips to the dealer to flush the heater core that is plugged. i understand from searching the internet this is due to the dex-cool antifreeze that gm puts in the car and that there are lawsuits against gm regarding this. the last time i had this done the dealer told me if it happened again that a new core would have to be installed at a cost of $650+. the core is now plugged once again.*ak

 No heat at 50,000 miles --vehicle cooling system flushed by independent garage 12-31-02. dex-cool renewed at this time. cost $160.00. in april 2003 no heat again. i drained dex-cool and used system cleaner twice for approximately 6 hours each time with heater on. i filled system with regular prestone glycol based antifreeze. no problems to date. the original dex-cool was a muddy sludge when replaced and the second charge of dex-cool was already changing colors and thickening after only 4 months when it too was replaced. dex-cool does not live up to the manufacturers claims or the dealers representations. i am a federally licensed aircraft maintenance technician working for a major airline for 14 years and would be happy to give a deposition in regards to this matter. *nlm

 Oil coiler lines leaked from the day i bought it from the dealer. dealer definitely knew and cleaned it up before i got it. 1st set of lines from radiator to oil filter replaced a few months after purchase in 2001. second set from filter to motor now need replacing. evidently, this is a very common problem. wipers have their own agenda. with the mist setting to clean windows, wipers stay on for as long as they want. with the second mist, they don't stay on as long. by the third mist, wipers act normal. always happens. turn signal flasher sound started without the use of the turn signal. it stays on for random lengths of time, and makes the sound in regular, and irregular patterns. replacing multifunction switch - as several have before me. dealer knew exactly what the problem was. tranfer case leaks lube. 4-wheel drive messed up because of empty case. added lube and hope no tranmission problems arrise. cv joint replaced 4 months after purchase. hood latch about to break. when pulling on leaver, barely is able to pop hood. feels like wire is going to snap. waiting for the next problem to occur - it has been nonstop. gm designed a terrible vehicle. i am very dissatisfied and i regret ever buying it.

 Consumers mechanic at the time of service noticed that the antifreeze on the top of the radiator had jelled similar to the form of peanut butter. the mechanic suggested that flushing the radiator would be logical to correct the problem, but other problems may occur in the cooling system. after the flushing, the water pump started leaking and the thermostat malfunctioned, on june 29th the heater core ruptured and caused extensive water damage in the floorboard, the vehicle continued running hot and was losing antifreeze, and on july 18th the radiator was replaced. consumers mileage is over the warranty amount.*scc

 Chevrolet dexcool coolant not good for 100,000 miles as advertised. two previous radiator flushes, one was one month prior to engine failure. told due to overheat despite no signs of overheat. chevy dealer says no signs of cooling system having ever been flushed despite another chevy dealer flushing system approximately 1000 miles previously. chevy and texaco state vehicle must be driven for extended periods (20,000 miles) with low coolant levels to start corrosion clogging up cooling system. not so in this case. system had been flushed and filled by chevy dealer on 6-11-2. aproximately 1000 miles later, on 7-8-2, chevy dealer notes buildup in cooling system again. coolant system had not been low, and had not been extended period. remanufactured engine and new radiator being installed, chevy denies any knowledge of problems of this sort with dexcool.*ak

 Dex-cool apparently changes state from a semi clear oragnge liquid to a muddy murky corrosive material. chevrolet has issued a service bulletin 99-06-02-012b...coolant is suppose to last 150,000 miles it was flushed 30 days ago and it has again changed to the muddy corrosive liquid...it also has eaten through my radiator core. why if they are aware of this problem as indicated by their issuance of a service bulletin why do they not recall and repair or replace engines and other components damaged by this corrosion.*ak
