Ticking noise under hood when engine is running. Diagnosed as leaking exhaust manifold. Bolts securing exhaust manifold broken. Repair requires removing cylinder head to remove old bolts. Cost estimated at $2,000 plus. Complaint filed with chevrolet. Claim initially denied. Continue to ask for assistance. Vehicle is located at trecek chev in portage wisconsin and is available for inspection.
The exhaust manifold on my 2003 chevy trailblazer ext has cracked at 54000 miles, and must be replaced at a cost of around $400. I contacted gm directly, and was told that this is considered "normal wear and tear." I disagree. If that is the case, then why would I keep the vehicle, knowing I can anticipate another costly repair within the reasonable life of the vehicle. My local chevy dealers service manager tells me gm is repairing many of these parts on the 4.2 l. Engine of not only the trailblazer, but other vehicles as well. A local aftermarket parts store also says his suppliers have many of these parts on hand. More than one might expect if this were an unexpected occurrence. I believe gm knows it has a part that is unsound, but it is unwilling to correct the problem at its expense. An exhaust manifold is not supposed to fail within less than 4 years, and at 54000 miles. That is not "normal wear and tear.
Rear AC/engine coolant line was rubbed thru due to the defective installation of a heat shield. The two lines provide freon and engine coolant to the rear AC/heater. The gm part number is 15113349 and is on national back order because this part is not suppose to fail. Gm currently has over 100 open tickets where this part is failing and they do not have any supply of replacement parts as this pipe is an aluminum pipe that ones from the front to the back and is not suppose to fail.
I own a 2003 chevy trailblazer lt @ 35,825 miles I reported my vehicle binds up on turns & of course the garage found nothing (drove it 20 miles for comparison @ the time). So now that I am up to 82,090 miles now I mention suspension issues still & of course they find both lower ball joints need replaced @ $320.06 & left outer tie rod end broken @ $170.80. Also they inform me I need to replace 3 of my 4 stabilizer bar links are loose & rattling @ an estimate of $320.00 (haven't done yet) also, I have looked on a website called mycarstats.com & found many others with these same issues with this vehicle @ much lower mileage & where tie rod issue caused an accident -- they weren't as lucky as me. Also people I work with who have this same yr & model vehicle have had to have ball joints, sway bars replaced, and other suspension work @ lower mileages. I also had an issue with my 4-wheel drive becoming inoperative & this did almost cause me to wreck going up hill during winter weather. They replaced front differential engagement actuator. All these things in my mind should not have happened at these mileages. The 4-wheel drive quit @ 80,000 miles. All these issues can create safe driving issues for the consumer especially someone who pays over $30,000 for a vehicle when it's new. Let me add now that the latest expensive repair to add to my list is the fan clutch assembly on my engine cooling fan system $573.00 -- also found many gm owners of bravada, rainers, envoys & trailblazers experiencing this items failure too.
Dt: left driver's side outside mirror is not holding the correct settings, and clicks constantly. The mirror is hitting against something, and turns completely to the ground. When using keyless entry the mirrors also turn to the ground. The mirror is changing by itself, and it is not going back to the correct setting. The mirror is always making a clicking noise and it is facing downward. There is no problem with the right side. The dealer replaced the right side mirror, and from then on the left side has not worked. Consumer has taken vehicle to dealership 4 or 5 times to be checked. Dealership insists the mirror is working fine. But as soon as the consumer leaves the dealership the mirror will work for a couple of hours and then stop working properly. Consumer took the vehicle to the dealership and the mechanic didn't write down the problem with the mirror in his paperwork, and this happened more than once. *ak when shifting from park to reverse the vehicle jerked at times. The engine control module was reprogrammed. The consumer believes that the reprogramming resulted in poor fuel economy. The cd player made a hissing noise. When the brakes were applied they would grind. The 4-wheel drive switch shorted. Windshield wiper motor failed. Right side tag light bulb blew.
