 I bought the 2000 blazer used just over a year ago and have had nothing but problems. to begin, i replaced the alternator, fuel pump, and virtually all suspension components in the front end with just over 65,000 miles. on vacation during one of the hottest days of the year traveling home the blazer over heated and left my family and i stranded on a major interstate with no a/c for nearly an hour before getting towed to the worst chevrolet dealer in the country(richmond, va). we were forced to pay for a new radiator and miscellaneous parts totaling over $600. they said the coolant system was full of rust and the radiator was plugged and could not be reused. now i'm experiencing the service engine soon that will not go out. after numerous trips to the dealer that started with leaking oil cooler lines, they said that the crank sensor was going bad. i replaced it, still the light stays on. next they say there is a misfire in cylinder 2, i replace the plugs, wires, rotor, and cap. still the light stays on. all of these repairs within the first 14 months of owning this junk and it is not anywhere near being paid for. gm needs to fix these problems. i have spoke with other blazer owners and they too have experienced nothing but trouble. and the big 3 wonder why they are losing customers and market share. have they ever heard of quality? looks like i'm going foreign. *jb

 The oil cooler lines are leaking on my 2000 blazer( with only 54,248 miles). the mechanic who changed the oil today stated that he has yet to service a blazer that didn't have leaking lines eventually. interesting! he also stated that he didn't understand why there has not been a recall. if this is not the proper place to report this, please let me know. perhaps you can also direct me to the correct place. thank you.
ENGINE AND ENGINE COOLING - COOLING SYSTEM

 I have a 2000 blazer lt with 128,000 miles that has had heating/cooling system problems for several years. had dex-cool in system which i monitored regularly to make sure has topped up. gm states dex-cool is maint free to 155,000 miles. when vehicle reached 100,000 miles, i began to loose heat. i noticed a crystal-like residue floating in coolant. drained, back flushed heater core and flushed system 3 times then added prestone (green) coolant. after about 10,000 miles began to loose heat again, repeated flush and fill. every year since, when colder weather sets in, the same problem shows up and i go through the same flush and fill procedure. dex-cool has left so much sludge throughout the system i can't get it all out and it continues to plug the system. i have replaced two water pumps, three thermostats and have spent hundreds of dollars just doing flush and fills. engine temp will be good for the first few weeks after a f & f then begins to run hot again with the smell of coolant in and around the vehicle. there are no visible leaks on the ground or on the block. all engine vacuums check ok. all other regular maint done when required. last f & f done 08-30-2009 and vehicle is starting to run hot already/again. *tr

 My 2000 blazer ls zr2 has 68000 miles on it. around november 2005, when i needed my heater in the mornings, i noticed that it would not blow any hot air. i have had the cooling system flushed and replaced the thermostat and still have no heat. i can smell coolant every now and then while i am driving. so, i am led to believe that my heater core is leaking and or blocked. i have done some searching around the internet and have noticed that this is a common problem with blazer's and it is caused by the dex-cool cooling forming a sludge in the cooling system. i feel that gm should be responsible for my repairs, as they have known of this issue for years, yet still continue to manufacture vehicles with this type of coolant anyhow. *nm

 Problem with the dex-cool system in my 2000 chev blazer---heater went out july 2004, was under extended warranty and heater core replaced, radiator was flushed at the same time. one year later vehicle over-heating again, no longer under ext warranty...paid $212 for the flush today and filed complaint w/ gm due to the obvious problem which they deny with dex-cool ( 8 states have class-action suits). was told by gm rep that the coolant system is a maintainence item and they could not assist or accept responsibility in the reapair cost. spoke with the gm dealership who argued my case, asked what maintainence required on my part, since the dex-cool maint schedule is 155k miles, maint free---my vehicle has 70k miles and second flush in 12 mo period. was told by dealership that nothing i could really do to maintain, just keep check on coolant level every oil change, and system could fail again at any time--no guaranteee and the dealership also argued with gm rep---that there is a problem with dex-cool antifreeze.......i paid the cost, but after purchasing gm products for the past 30 years, if i am faced with additional cost of an apparent defect by the manufacturer...i will go to another make of car---thank you for your time

 Blazer seeping oil from oil pan, will not fix only if i pay 75% due to 90 day warranty,and told if they would fix it i would only create more problems, it was also told by dealer and chevy that it is normal for year and mileage, i don't think so with 47,000 miles, when i owned a 97 chevy with 97,000 miles , no leaks but salesman knew of it 3 weeks after purchase when 30 day bumper to bumper existed,was at dealership july 6, 2006 for all items but chevy nor dealership documented it or the grease fittings, lube, check fluid levels like was suppose to do, salesman checked fluids for me after they neglected to do their job.. so chevy says can't go by salesman because he no longer works there, seeping oil from oil pan is not normal, i didn't receive a odometer paper on it or my trade in.. i feel they are doing me wrong and chevy is backing them up, i even gave salesman number and told them i have a note pad here of all that was to be done with pages after on note pad written on after that day and they won't listen. they never gave me correct mileage on it when i purchased the vehicle. *jb

 Accelerator sticking. from standing start, accelerators pedal requires considerable pressure to move from resting position. as pedal is depressed, vehicle jumps forward before operator can remove pressure. complaints to dealer resulted in the estimate of a $100.00 charge to clean carbon from throttle body and apply a chemical treatment to help prevent further sticking. this should not be a maintenance item as it could result in uncontrolled acceleration, possible loss of control, and accident. dealer diagnosis was almost instantaneous so the problem must be a common one.*nm

 The 2000 chevy blazer is a mechanical and saftey nightmare! this vehicle was purchased brand new/lease and i have had problems from the beginning. the exhaust has never sounded normal; it has a preignition (rattle-like) noise, and i was recently told that the catalytic converter is bad. the alternator failed at approximately 12000 miles. the hazard lights failed in april 2002, and the brake lights failed shortly after. the steering problems include: clunking when turning to the left, a shift in the front end (feels like the front pass. side steering components are loose). the vehicle is almost impossible to control on freeway due to loose steering and inability to control on transitioning/uneven pavement. the dealer has replaced front pass-side tierod and stabilizer, and the steering wheel now has a 12-15degree, off-center, right list. cutter cheverolet of hawaii is now having us try to reproduce the problem(s), and trying everything they can to not accept that the vehicle is, in fact, a lemon! what does it take to prove that a vehicle is just not a good vehicle; does my family have to get injured or die to prove there is a problem! we are a gm-family(entitled to gm family discounts), and this is how we get treated. . .no acceptence of responsibility or pride/honesty in their product. i will never buy another gm product; ever! the dealership, gm factory, and gmac should rightfully accept responsibility and take the vehicle back. i have better things to pay $384.00 per month! japanese atomotive industry. . .here we come! ~ don schrader, pearl harbor, hawaii. *ak

 The handle that allows you to recline the seat broke off flushed with the seat, this happened to both the driver and passenger seats in june 2005. the hood will not pop up when the lever was pulled until one banged on the grill or the hood in certain spots, which just started in march of 2007. the gas mileage dropped from 20 mpg to 16 mpg within 6 months. the back glass stuck and was hard to open, started in 2006. when turning on the air conditioner (a/c ) the car had no power, i have to turn it off when accelerating on the interstate or on hills. if the cruise control was set it kicked off when the a/c was on. when i needed to stop quickly the brakes failed, and felt a grinding sensation through the pedal, but the mechanic changed the brakes and checked the rotors, but hasn't found any problem. suspected a defect somewhere in the brake system as of 2005. the fan kicked on all the time, even when the engine was cold, and in winter when first starting. one mechanic told me that in many blazers the catalytic converter broke off in the muffler, which had to be replaced. had been told this happened so much that most people left them off. too many other problems to mentioned. also, the horn worked only when it wanted to, problem in the steering wheel. *ak
