ENGINE AND ENGINE COOLING
03/21/2012167000
 While driving, the temperature gauge spiked and the check gauges light came on. one of the bolts that holds the thermostat housing to the manifold had sheared off due to bolt brittleness. this caused a serve loss of coolant and the remainder of the thermostat housing bolts to become broken off in the intake manifold. resulting in a repair of at least $1,000 due to having to replace the manifold. the shop was only able to extract one broken bolt from the manifold. this vehicle is a lemon. we have replaced everything on it, some things more than once including the engine, transmission, and multiple radiators all under 75,000 miles. we have replaced the gas cap to the radiator cap and even the windshield too. this will be the second intake manifold as the engine had to be replaced 5 years ago due to failure of the head gasket due to a faulty gm design on engines made between 2000 and 2004 and dexicool coolant issues.

 The heater and defroster failed to generate heat. no events leading up to failure. this fall when we needed the heat and window defroster just luke warm air was coming out. the intake hose to the heater was hot the out take hose was cold. this failure causes a major safety issue because the front window will not un-fog and the ice and snow will not melt off the front window. the driver can not see out of the front window. there is no warning to this problem. research this problem on the web and there are numerous other people and vehicles with the same problem. it appears to be caused dex-cool coolant. this web site http://www.geocities.com/b_gillie/dexcool_problems.html has more information on this problem. *jb

 I have had to replace the intake manifold gasket on 3 chevrolets in the past 3 three years today being the the third. if there is a problem with the gaskets or coolant the repair should be done at no cost to the consumer

 Dt*: the contact stated after parking the vehicle for a few minutes, the vehicle would not restart. when the key was turned in the ignition the engine would not turn over but only made a whining noise. the vehicle was towed to an independent repair shop, upon inspection the engine had seized. the timing chain had fractured, the sparks plugs had melted and the pistons had failed. the dealer and manufacturer were alerted.

 Immediately following purchase of a 2002 chevrolet blazer in august 2002, i noticed a loud roaring noise coming from under the hood which occured mostly upon startup when engine was cold and put into drive gear. this noise was also intermittently noticed after coming to a stop and then accelerating. by the time i drove it back to the dealership, it was not doing it. since purchase, 2 replacement batteries have been installed. service dept at dealership said alternator was draining the battery and replaced the alternator. car is still doing this but dealer is unable to duplicate and saying loud roar is most likely normal. now several acquaintances have said they had the exact same problem with their blazers even though they were a different year model. once the warranty runs out, this problem could add up to quite an expense.*ak

 After engine has warmed up, there is a constant enging/tapping/rattle noise similar to the sound that bad lifters make. this sound is prevalent under all conditions and more pronounced on acceleration. i brought it to the dealership several times and they indicated it was a normal sound per detroit. detroit has a document id#843248 that addresses this problem. i complained to gm and they have extended the warranty on the engine to 100,000 miles or 11/27/07 whichever comes first. i am still not satisfied as the noise is consistent and an irritant. i have looked at your site for other similar complaints and do not see any. there must be a mechanical fix to this problem but it is being ignored. the engine sound has increased since it was first noticed indecember, 2002 and reported to the dealership.*ak

 Noticed noise; have taken to dealers 8 times and they can not fine the cause of noise; now gm representive anthony teta says it is inherit design problem; rox covert told me he would fix it, replace it or give me my money back - pickup it up 5/20 and because it didn't make the sound returned to me. i do not want to put up with this noise, i'm tired of the run around, and very disappointed with my first new vehicle purchase that covert, chevrolet or gmc will not try to right this problemed vehicle. please help me if you can.*ak

 Ever since i bought this vehicle i have had nothing but trouble with it. since i have bought it in july it has been in the shop for approx. 10 times. the first day i brought it home it would not go into reverse. needless to say it already has a new transmission. i have also had problems with the rear middle seat belt locking up and making it impossible to wear. i have brougt this problem up to the dealer several times and they have even replaced all of the seat belts, but it still persists. i have now been told that it is because of infant seats, however how can this vehicle be suited for five passengers when in reality it can only hold four. another problem i have had with this vehicle is the heater blower failed to work. i brought my vehicle back to the shop and they replaced it. i have also had problems with the 4wd system switching between 2hi. the dealer has installed a new switch as well, so the problem has been solved. one of my newest concerns is randomly when i start the vehicle in the morning the engine revs up really loud. the loud noise gets even louder when you accelerate the vehicle. when bringing in this problem to the shop they said that it is the fan clutch and that it is normal. i find this hard to believe. people that hear the noise are in disbelief that a new vehicle can make such a noise. i also am having a concern with squeaky breaks in the front end. the shop states that semimetallic brakes will make some noise at times. in all of the cars i have owned i would have never thought that a 2002 would have squeaky brakes and that it would be normal and unable to fix. i am very concerned about this vehicle and i question how reliable and safe we are driving it. gm will not help me in replacing this vehicle so i guess my next step is the attorney general. *ak

 While driving my trailblazer the engine failed as i was stoping for a red light. luckily there were no cars near me and i was able to safely bring the car to a stop and force it to the curb. after about 15 minutes i was able to re-start the engine and i drove it to the dealership. they inspected the car, called chevrolet with their diagnosis and were immeadiately informed by chevrolet to the amazment of the serivce manager at the dealership that a new engine was needed. it seems they knew that a new engine was needed so quickly as this is a major problem. a search on your web site and the trailblazer forum at edmunds.com shows that this is a wide spread problem. it is apparent that gm has knowingly placed defective engines in the 2002 trailblazer. what would have happended if my engine failed on the highway going 70 miles an hour? the nhtsa must address this situation before people die from this. this has all the makings of another ford pinto fiasco.*ak
