1996 Chevrolet Blazer engine complaints
Page 2 of 6: complaints 11 to 40 of 150, newest first, as owners wrote them.
Most of the problems that surfaced had already been repaired at least once. *ph most of the problems had already been repaired at least once under warranty and have recurred. The A/C seal leaked and needed a pump. There were problems with the idler pulley, oil filter lines, crank shaft,door hinges, power steering, throttle positioner sensor 2, left front axle seal, and the differential side covers. *sc *mr
Engine coolant at 50,000 miles turned to a muddy substance. 1 yr later and 30,000 miles it has happened again. The dealer did a power flush at the 50,000 and gm covered 2/3rds of bill now I am told I must change heater core and power flush again at a cost of over $800. . Gm will not cover any expense. It is said that my anti freeze should last 100,000 miles ,as you can see it did not last 50,000 miles.
Our blazer started over heating, we had it flushed due to a mud looking sluge in the cooling system and a new thermostat put in. About a month later it started over heating again. We again had it flushed and another new thermostat put in. A few weeks later it again over heated we had it towed in and found out that this time it had caused the motor to blow. We contacted gm they said it was not their proublem it was dexcool, we contacted dexcool and they said it was gm's proublem. We got the run around so we contacted the atty generals office and filled a complaint with them.
I have had to change the oil coolant lines on my 1996 s-10 blazer 5 times since I have owned the auto. I purcheased it in 1998. It was still under warranty then, and the first time they did the work free of charge. Since then, every 12-18 months I find oil dripping in my garage, and I am told it is these lines. I have been told by 3 different mechanics that these vehicles are notorious for this problem. Can't anything be done!!
My 1996 chevrolet blazer with less than 53,000 miles has no heat and started overheating. I took it for service and was informed that the dexcool that was guaranteed for 100,000 miles had failed. The radiator was partially blocked and the heater core was blocked. Both the radiator and the heater core need to be replaced because of the sludge and rust that was in the cooling system.
Vehicle engine caught on fire while driving.*mr the consumer stopped at middle ridge service plaza and noticed smoke coming from the engine. The fire was extinguished with a fire extinguisher. Damage to the vehicle consisted of hoses, wires and insulation under hood. Consumer had no recent engine problems. *ph
Replaced head gaskets at 48k and again at 80k. Either dexcool eats the gaskets, or the gaskets go bad and let air into the cooling system which causes the dexcool to go bad. I read a lot of complaints about dexcool, head gaskets, and 1996 blazers. There must be a connection.
I have a 96 chevy blazer with cooling problems. I have replaced the water pump 2 times in the last yr. The radiator needs to be flushed and clean about every 2 months due to slugged and rust build up. I have also had the upper ball joints break on me.
1996 chevrolet blazer has had numerous problems with cooling system due to bad anti-freeze general motors used in the vehicle of this vintage. They charged me to have the system flushed out because the anti-freeze would clog the heater coils. No heater in winter. Previously the vehicle was over heated and dealership replaced the thermostat and water pump plus seals and head gasket due to the engine running too hot. This is the 4th time I'm returning it and now they want me repair or replace the radiator. It is still running hot. It is my understanding from talking to the mechanics that this is a problem for vehicle of this vintage and it took a couple of years for gm to change anti-freeze manufacturers. Do I have any recourse?
Dealer replaced heater core due to leak and found sludge in cooling system (dex cool). Heater core replaced and system flushed 4 times. Heater core replaced again on 1/19/03, water pump replaced in 2/03. Radiator has large leak 5/22/03. Sludge visible in radiator and overflow bottle. Dealer/gm indicates problem with sludge build up caused by owner not maintaining system. Head gasket replaced in 2001 and windshield wiper circuit board in 2001 (bad solder joint) - gm indicated the windshield wiper problem not associated with VIN number. All costs out of pocket.
I own a 1996 chevrolet blazer which I purchased new in 1996. It now has 59,000 miles on it. We have regularly scheduled maintenance done on the car, along with scheduled oil changes, checking belts, hoses, etc. We are constantly having our brakes repaired/replaced. Last year we needed to have a brake booster replaced which cost us over $700 and today we were told that our "entire" cooling system is corroded...$1,900. At 59,000 miles I certainly don't think this should have happened.
All oxygen sensor failed transmission slipping. 13 sensors fail.
Windshield wipers front & rear failed, water pump quit, drive shaft broke, ball joints right front broke, heater quit, air conditioner quit. Drivers side rear view mirror fell off, steering problems, brake problems, universal joints worn out, cracked front rotors,etc.
Just brought 96 blazerls with 82,000 in dec.02. Was told that the only problem was they had to have the transmission replaced at 20,000. Well,83,000 miles the heater was on hot blowing when I noticed that it turn cold and the gage went to the red zone. I immediately turn swiches off on the blower it went back to normal. Two days later it happen again but I turn off the heater and blower completely it went back to normal. We thought the termostact got stuck and replaced it . At that time we notice that it was gel up over the termostact, after replacing it , we tested drove it and it still did the same thing again. We looked at the radiator and found that it was gel up and look like rubber. We then decided to check the fluid in the transmission we noticed that the dipped stick was rusted on the outside and was rusted the length of the stick the fluid was rusted. We will now have to flushed the radiator and transmission. I had checked your site and found no recalls or service bulletins on the geling and transmissions before buying. Tell today when I decided to checked out complaints and found that there was 54 and couple with the same problems of geling and transmission problems. So I decided to check out 98 because my sisterinlaw had just brought one and no recalls or service bulletins but they are compalints of cool heating (probably from geling anitifreeze) and transmissions being replaced once ,twice and I guy 3 times. So I check 2001 and they was someone else replacing a transmission. Something is very wrong when there is geling of antifreeze from 96 to 98 and replacing transmissions left and right since 96. To me chevrolet has a bad transmission problems and geling problems in these blazers getting away with it. From now on I'll check out complaints before recalls or service bulletins there's the consumers eyes and ears.
Consumer stated vehicle over heated, due to a blown head gasket.
All items looked at by dealer, dealer also informed me that these are common problems chevrolet is aware of. Odd that they don't do anything about them. Dt
Enough oil is not being supplied to engine. Dealer has been notified, please provide further information.
In jan 99, thermostat appeared to fail and when I opened the radiator cap, noticed what looked like mud/grit in cap. Took the truck to the chevrolet dealer, they said they did not know what it was. Ended up replacing intake manifold gasket, pulling and repairing/cleaning radiator and replacing thermostat. In july 2002, truck overheated again. Took it to firestone where they recommended $1200 in repairs to flush out "coagulated" coolant (dexcool). Ended up replacing radiator, radiator cap, and thermostat (again) and flushing entire coolant system. Firestone personnel said this was a recurring problem on the blazers with the dexcool breaking down and turning into a brown, muddy, gummy substance. Accoding to firestone, gm has several tech bulletins out on this, but they refuse to do anything about it. This dexcool broke down after only 30,000 miles. Why has nothing been done about this? Gm is knowingly selling a deficient product and they refuse to stand behind it. Please, can someone out there help us!?!?!?!
Vehicle has a continual problem with battery going dead, dealer can not find the problem even after disconnecting everything to see what was draining the battery.
02/17/00 (36417 miles)--cooling system flushed per tsb #99-06-02-012 and heater core replaced. 6/15/00 (39128 miles)--cooling system flushed per tsb. 11/15/00 (42626 miles)--cooling system flushed per tsb. 6/2/02 (60,715 miles)--radiator and heater core replacement and cooling system flush required.
Consumer states vehicle has an engine cooling system problem.(dex-cool engine coolant). Nlm because of crystalization, the cooling system needs repair. Gm refuses to offer any type of assistance.
Radiator clogged with gunk caused vehicle to overheat. This has reoccurred within a year after dealership repaired the problem. Please describe details.
The consumer states that he suffered loss of braking after the ABS was fixed on recall due to the dealer using defective parts. Every light on the vehicle went out while the consumer was driving, consumer believes the service department improperly installed the wires while performing the recall.
While driving engine does not heat up to proper temperature in the winter months, and in summer months it overheats. Chevrolet has admitted to the problem, but will not do anything about it. Please provide any further information.
Entire cooling system clogged with a sandy substance. Mechanic says radiator, water pump, thermostated, and a number of other componets need to be replaced at a cost of over $1500.00. Mechanic says he is seeing this on a regular basis with 1996 blazers. While a number of complaints in your database point to problems with the dexi-cool coolant, the mechanic says in his view it is not the coolant as this problem is only with 1996 blazers. He believes it is sand from a faulty problem with the engine blocks were cast. The excess sand is now breaking off and clogging the coolant systems causing major repairs. Gm has ignored all complaints. This is a major problem as the vehicles are overheating and resulting in people getting stranded on highways, etc.

This cooling system failure has resulted in my having to replace the heater core and hoses as well as the radiator due to the amount and thickness of the corrosion/rust inside. The system will have to be flushed...chevy is aware of this issue as referenced by their repair bulletins...the extend and cost of the damage is understated.... Im out of pocket $1400 to replace a radiator a heating core and other component due to not being notified sooner about the possibility of the problem occurring and thereby having the vehicle inspected for the probably issue!
There is a constant oil leak coming from under the hood, mechanic states oil gasket malfunctioned. *ak
Many problems are continuing. Currently, the front suspension needs repaired, the brakes were replaced at 18000 and are now gone again, the rear seals are leaking damaging the rear brakes, the drive lights still flash intermittently, a smell of gasoline is in the vehicle after refueling, the engine pings no matter what fuel is used. Nothing the dealer has done has solved the multitude of problems. Seat belt problems on passenger side, interior trim fell off, on and on.
