Tl* the contact owns a 2004 chevrolet tahoe. The contact stated that while driving at approximately 40 MPH, the engine warning light illuminated. The contact discovered that the engine overheated because the coolant reservoir was empty. The contact dispensed coolant into the reservoir. The vehicle was taken to the dealer, who informed that the engine block and the cylinder head were improperly designed and contributed to the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 92,000. The VIN was not available.
Tl* the contact owns a 2004 chevrolet tahoe. While driving at approximately 60 MPH, the vehicle stalled without warning. The vehicle failed to restart and was towed to the contact's residence where an independent mechanic diagnosed that the fuel injectors and spark plugs needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 145,000.
I got an engine light about beginning of november code was p0430, definition is "catalyst system efficiency bank 2", this could be caused by high engine oil or coolant usage. Knowing this I check my tahoe for coolant leaks, no visible leaks at all, I take the cover off the cylinder head and I find a lot of sludge, now I know where the antifreeze is going. My tahoe is still running but with the engine light on and with a misfire due to the porous cylinder head, don't know how much more is going to last and can't really stop the tahoe because it's a daily driver.
Vehicle begins to idle rough, noticed tahoe consumes coolant at an abnormal rate, approximately 1gal/month!! Our local chevy dealer coded for flex fuel sensor replacement $1400! No change in condition of vehicle. Idle is now very very low! My wife picks up our kids, tahoe would stop running while making a turn at an intersection!!! No power = no power steering!! She barely avoids an accident!! She along with the kids will not ride in the (family car) the tahoe until it is fixed. Don't trust our local chevy dealership, due to lack of integrity!! We were proud and loyal chevy owners, we also own a 91 gmc sierra 1500 5.7l with 232000 mi. And a 98 chevy 1500 v-6 113590 mi pick-up, both still running very strong with absolutely no issues! Researched this issue, defective castech heads, gm is aware of this problem, tsb 06-06-01-019b, very disappointed to state the least of how gm is handling this situation. Complained to gm corporate, they stated they will not be able to assist and that we would have to take it to our local dealership where integrity runs very thin!! I am a proud msgt in the usaf, and full time firefighter, if we cant trust "the heartbeat of america," who the hell can we trust!! This problem has cost put our family in the hole for $3800 now and it looks like if we move forward to fix ourselves we will be in excess of $5800 for the heads to be serviced or $8600 for new motor swap!!! Gm needs to take responsibility recall this and get this issue squared away and maybe salvage what is left of a loyal gm supporter.
Vehicle registered "reduced engine power" while I was on the highway, I was able to get to the shoulder, online research showed numerous incidents involving the throttle body sensor and the wires crimping, there was something about the wiring harness being covered by gm but it does not appear on a recall list.
The engine cylinder heads for the 5.3l gm motors built by castech leak coolant into the engine causing engine overheat and internal engine failures. Gm has issued a technical bulletin #060601019b to address the issue and diagnose the issue. Gm will not offer customers any financial help in the replacement of the defective parts. This issue effects the safety of the vehicle and the safety of the persons in and around the vehicle. The fouled engine oil causes the lifters to fail, the oil pressure to drop and the engine to lock up due to lack of lubrication by the fouled oil and the driver has no way of knowing this is happening as there is no external indicators.
Drove vehicle out of town on christmas holiday trip. After being parked overnight starting vehicle next am big cloud of white gray smoke upon start. Coolant low. Refilled coolant and drove home. Now vehicle constantly leaks coolant with no apparent leak under vehicle or in engine compartment. Oil sludges between oil changes. White smoke after a 30 min drive every time. Gm has bulletin out for bad heads installed and the part number and symptoms matched cracked heads on my vehicle. Dealer aware and sees often not only in this vehicle but all 5.3 engines from a certain time span. Dealer states will only fix at cost of consumer even though bulletin is known. This could cause an overheat situation or engine failure at a bad time or worse. Why are they not made to stand behind this when problem is known? A quick search on google will overwhelm a computer with so many accounts of this problem.
I was driving down the road when my 2004 chevrolet tahoe caught on fire burning to the ground. The report from the fire department says that the fire started due to failure of equipment or a heat source and that there were no human factors contributing to the fire.while looking on the internet I have found at least one other person that has encountered the same problem with her 2004 chevrolet tahoe.
The tahoe has known faulty castech cylinders which cause coolant to leak with no explanation. Over the winter I have had unexplained coolant/antifreeze issue with no found leaks (coolant would be bone dry after a couple weeks of filling it). I was told the issue is probably caused by the faulty porous cylinder heads made by castech installed in gm's from 2001 - 2006. This tahoe has a total of 80,000 miles now and experiencing issues due to known faulty parts installed by gm. Chevrolet has to be aware of the danger they are putting their customers in by not having a recall of a faulty part located in the engine. How there has not been a recall I do not understand. How chevrolet expect the customer to pay 3-4k to replace their faulty head is ludicrous.
Gm used defective engine cylinder heads for millions of 4.8/5.3 liter v8 engines from 2001-2006. The cylinder heads crack causing coolant to flow into the oil and cause excessive sludge to form and cause engine failure. Gm knows about the problem and issued tsb to it's service departments:1 information on gradual coolant loss over time with no evidence of leak found #06-06-01-019b - (06/12/2007). These defective cylinder heads can cause overheating and complete engine failure.
Cylinder heads are leaking coolant into the engine. This causes excessive lifter noise when first started after the engine has been sitting for several hours and requires coolant to be added almost daily. This condition will eventually ruin the engine requiring the engine to be replaced. This problem is known by gm to be a defect in the casting process, yet no help is offered by gm to fix the problem.
Tl* the contact owns a 2004 chevrolet tahoe. The contact stated that there was a cooling fluid leak, and she had to add cooling fluid consistently. The vehicle was taken to a private mechanic, who stated that there was cooling fluid leaking into the oil pan in the engine. The failure was reported to the manufacturer who acknowledged there was a technical service bulletin, but refused to provide assistance for the repair. The failure mileage was 84,000. The current mileage was 86,000.
Engine started with a ticking noise when cold. Would go away after engine warmed up. Upon inspection found 2 exhaust manifold bolts sheared on #7 cylinder, 1 broken on #8. Ticking coming from exhaust leak on #7. Upon research found that this is a common issue with these engines. Why is there no recall or safety notice as it presents a real hazard for fire and exhaust fumes entering passenger compartment.
Tl* the contact owns a 2004 chevrolet tahoe. The contact stated that the cylinder heads fractured on the vehicle and the engine overheated. The contact had the vehicle inspected by a mechanic and it was found that coolant leaked into the engine. The contact was told that if this continues the engine will eventually fail. The vehicle was not repaired. The VIN was not available. The failure mileage was 115,000 and the current mileage was 117,000.
I started having problems with my 2004 chevy tahoe is september 2009 when the vehicle only had 71,000 miles. The vehicle was using a lot of oil and I took it to the dealership and they notified me that their was no oil leaks and performed a compression test. Since that date I have needed to add additional oil in between oil changes. In the last couple of months it started to use a lot of coolant. I have added about 4 gallons of coolant in the past two months. I took the vehicle to the dealer and was notified that the left cylinder head was leaking coolant in the engine. After further research I found that the castech heads in this model were porous which caused them to crack. The dealer is recommending that the engine be replaced at a cost of $6400. I feel chevy should be responsible for this repair since they are aware that the problem has to do with the castech heads.
Tl* the contact owns a 2004 chevrolet tahoe. The contact stated that coolant was slowly leaking into the cylinder head, causing the engine to overheat. The dealer was notified of the failure who advised that the cylinder head be replaced. There were no recalls for the failure. The manufacturer was notified who advised that the contact should take the vehicle to the dealer for repairs. They offered no further assistance. The failure mileage was 75,000 and the current mileage was 105,000.
Blower resistor caught fire inside of the vehicle on passenger side where it plugs into the front blower motor.
Coolant loss without signs of leak. Loss of oil with no signs of leak. Lifters chattering on cold start. Puff of white smoke on start-up. Loss of oil pressure. Defective cylinder heads made by castech.
The gm 5.3l built between 2002 and 2006 using castek corporation engine heads were incorrectly built per gm and castek. The heads leak engine coolant into the combustion chambers and burns off causing the engine to overheat. Gm has issued a technical bulletin regarding this issue and requests the heads be changed out but at the clients expense. With the loss of coolant and inevitable engine damage this is a safety hazard and should be a recall and replaced at gm cost. Technical bulletin 06-06-01-019b issued 6/12/2007.
2004 chevy tahoe with castech heads has a history of running hot or overheating with little warning. In the cooler months, will fail to heat the interior of the vehicle without warning. Can leave drivers and passengers (likely children) without transportation in a harsh environment.

Consuming oil and water - needing 1-2 quarts of oil and 1 gallon water/coolant per 900 miles. No leaks, no dripping, no spots on garage floor. At start up, there is a large cloud of blue/white smoke from exhaust. Sometimes there is a very loud tapping in the engine until well after reaching normal temperature. Oil and water is being consumed internally - due to crack in cylinder head which is a known issue with certain engine blocks.
2004 tahoe, 79,000 miles. Engine overheated which could have caused fire if I had not noticed and stopped. Gm dealer says overheaing due to crack in cylinder head and confirmed tsb 06-06-01-019b (06/12/2007) applies to vehicle, which admits there is known manufacturing defect in certain cylinder heads which can cause engine coolant to leak internally causing overheating and potential engine failure. Dealer refuses to cover repair. I have pending complaint with gm customer service to pay for damage. I think this should be a recall as it can lead to overheating, engine failure and potential fire. There are multiple reports on internet of same problems by other owners.
I have been hearing a rattling sound underneath my car while driving. Also when I turn off the car, especially when the car has been driven for a while, I hear a popping noise, maybe from the muffler area. I was told today that the catalytic converter needs to be replaced. I bought the car new, so I don't understand how that could be already with only 85k on the car.
Tl*- the contact owns a 2004 chevrolet tahoe with an odometer reading of 80000 miles. The contact noticed that when driving for a long period of time and coming to a complete stop then start moving again the speedometer will stay at zero. The contact stated that the only way to get the speedometer to work again was to turn the vehicle off, then let it sit for a moment and restart. This problem made the contact run out of gas several times since the gas gauge did not working properly, the oil gauge wasincorrect as well. The contact took the vehicle to the dealer, and they told him that the instrument panel needed to be replaced.
Electrical panel does not work properly. Have not had a correct reading in months.
2004 chevy tahoe speedometer quit working. Stays on 55 MPH even when engine is off. Told it would be about $800 to fix. Now oil gauge is not working properly. It does not drop to zero. Oil in engine is at proper level.
So many... Where do I start? 1) at 9,000 mi. Intermediate shaft was replaced due to a popping feeling in the steering, at 16,000 mi. It is doing the same thing again. 2) at 9000 miles the instrument cluster was replaced due to a faulty tach motor making a buzzing/rattling sound, started making noise again at 13,000 miles took to dealer and said there is nothing wrong. 3) headlights flicker on and off on turns has been to the dealer 5 times since it had 9000 mi. 1st 2 times replaced a plug on alternator and said it was fixed, was not then said the found a bad connector still did not fix the problem. The problem still exists contacted gm and they were no help. 4) exhaust has been popping since new and sometimes after cool down sounds like something exploded 5) engine makes a noise when warmed up took in for service at 12000 miles and they cleaned oil pump pickup tube and said the oil pressure was not correct. This did not fix the problem took back in at 15000 and they stated no problem was found I was told the engine noise was normal. 6) the brakes pulsated when new took back at 59 mi. I was told to drive it and it would get better. Started again at 9000 mi. And they turned the rotors. Brakes started making a cracking noise in the front took in 3 times found no problem yet when I picked the vehicle up the last time at 15,000 mi the noise went away only to come back a week later. 7) when idling the vehicle vibrates bad!!!! Dash will rattle and you can feel it in the steering wheel. I was told this was normal when the A/C was on yet it's worse when the A/C is off. Now that A/C is making a terrible noise from inside the engine compartment and inside the climate control box area. 8) engine has a miss at idle.
Dt: the caller stated vehicle stalls. This happens when driving at slower speeds and idling. The engine hesitated just before it stalled. Dealer said the problem was in a computer chip the first time. The second time he had it in they told him he may be out of gas they could not duplicate the problem. Manufacturer was called and he filed a complaint with them. *ak
