Tl* the contact owns a 2003 chevrolet silverado 2500 hd. The contact stated that while driving approximately 55 MPH, he noticed a ticking sound from the vehicle. The noise became louder and the contact later discovered that the bearing and timing chain were damaged. Additionally, the transfer case did not contain any fluid. The vehicle was not taken to the dealer for further inspection. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure and current mileage was 195,000.
While driving, the check engine light comes on and "reduced engine power" is illuminated on the dash. Stepping on the gas does nothing. The vehicle just coasts along and runs rough. I have to pull over and shut it off for a few seconds. Sometimes it doesn't clear the problem right away and needs to be restarted several times. There is no rhyme or reason as to when this happens. It happens almost every day, on busy expressways or on main roads and side roads. The gas pedal loses communication with the throttle body. This is nerve wracking when driving 65 MPH on the expressway and all of a sudden the vehicle wont respond to stepping on the gas pedal. Trying to get over several lanes to the side of the road is dangerous when there is no acceleration. It is also bad when on a busy, main road, the vehicle "acts up". I have to pull over, blocking traffic, until I can get it going again.
We were traveling east on I-90 in mass. Traffic came to a sudden stop. When the brakes were applied the truck began to slow and then the brake pedal went to the floor. Upon investigation after the crash we found at least two badly corroded brake lines that had burst.
This is the 3rd time for injectors in our 2003 injectors, not one injector...all 8. Lucky this time just 4 hrs. From home and somebody to come with trailer to pick us up. Seems injectors only last 20 tp 30,000 miles and they are gone cracked. Gm wont back them knowing they are a problem, and $5,000.00 each time they are replaced. Gm injectors are junk out the door and leaving hundreds of owners stranded on highway and suffering tow bill and repairs, but this time we almost got rear ended by a semi truck which slammed on his breaks blowing a tire to miss us and our horse trailer with 3 horses in it. The abf trucker that almost hit us in the rear pulled over as we did, and told him the truck just stalled, we pulled the hood and diesel fuel was all over the place and he stated I cracked my injectors, the local gm dealer told me the same thing and that year has plenty of problems with injectors but gm wont replace them. What's it going to take, another bus load of kids killed to resolve this issue?? Another $5,000.00 donation to gm.
Fuel injectors replaced all 8 injectors at 34901 miles, again at 85039, and again at 141,000 and now again at 185,000.
I notice a ticking from the engine compartment over the last couple of days. I assumed it may be an exhaust leak and I was correct. This vehicle has a stainless steel exhaust system that should last a lifetime yet there seems to be a real problem with exhaust manifold bolts breaking off, causing exhaust leaks which pollute the air and ruin other vehicle components such as the catalytic converter. I am also thinking that the manifolds are warping causing the bolts to break. These repairs are very expensive and/or time consuming. Stainless steel bolts would have possibly prevented this problem. I understand that this problem affects 1999 to 2007 vehicles and I hereby request that a recall be forced upon the manufacturer. The manufacturer has been building cars long enough to know better. There is also a video on you - tube that explains this condition.
Tl* the contact owns a 2003 chevrolet silverado 2500 hd. The contact stated that while driving approximately 35 MPH, a loud noise emitted from the engine compartment and the engine warning light illuminated. The vehicle was taken to a private mechanic who informed the contact that the exhaust manifold had failed. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 79,000.
My 2003 silverado pickup truck has been found to have a common and recurrent problem. Exhaust manifold bolts break, and on the driver side rear, they can be expensive to repair. A few minutes of web searching on this topic produced a number of results and my conclusion is the issue is common. The online complaints also indicate that the success rate for the repair is not good, with many repaired vehicles having subsequent bolt failures. My vehicle is in an authorized chevy service garage having the bolts replaced. The original estimate was for $486, if cylinder head did not need to be removed. The service technician broke a tap off in the rear most bolt location. I don't know if it happened before head removal or after. It became necessary to remove the cylinder head and was requoted at $1600. A call was made to gm 3-6-12. The response was that my truck was out of warranty and there fore they could be of no assistance in the matter. I am certainly aware of the warranty terms. My issue is with the scale of this engineering/manufacturing defect and the cost to the owners. The issue can cause emissions problems due to catalytic converter failure and further expense.
This vehicle failed state safety inspection due to corroded brake lines and leaking exhaust around head gasket.
The heads of the bolts that hold the exhaust manifolds to the cylinder heads are breaking off for no apparent reason causing an exhaust leak.
I have had a exhaust leak that I finally pinpointed to be broken exhaust manifold bolts. The truck was bought new by me and has never had any exhaust work done. Now I have to take it to a dealer to have this expensive repair done. Apparently this seems to be an extensive problem, with these bolts. This I understand to be an extensive repair. Gm knows there is a problem with the bolts, why wont they make it right.
2003 chevrolet silverado 2500hd w/ 8.1l engine. With 59,000 miles. I noticed a ticking noise coming from the engine compartment. I took into a dealership for some other service and had them check this noise also. It turned out to be a warped right side exhaust manifold. I also know people that have this same engine in there motorhomes that have had the same problem.
Tl*the contact owns a 2003 chevrolet silverado 2500 hd. The contact stated that the vehicle stalled without warning while driving at any speed intermittently, but the failure became frequent, when the vehicle was turned off and within a few minutes it began to function normally. The vehicle was taken to the dealer who performed a diagnostic test and confirmed that the crank position sensor had failed. The manufacturer was notified and stated that the vehicle was not included in recall 07v521000 engine and engine cooling; they agreed to call him at a later date to inform him if they were going to assist with the repair. The vehicle was not repaired. The failure mileage was 2,000 and the current mileage was 105,000.
I have a 2003 chevy 2500 silverado with the 6 liter v8. 2 years ago I noticed a ticking sound from the engine compartment. After looking closer I found a broken exhaust manifold bolt on the right side. At that time the vehicle had about 130,000 miles on it. A couple months later while changing oil I found another broken bolt on the right side. This year while changing plugs I found another broken bolt on the left side. I was looking on the internet to get some tips on fixing the problem when I came across a utube video by carquestions and found out this is not just bad luck on my part it is a very wide spread problem and an obvious manufacturing defect by gm. This is not an easy fix and to get it done is more than I can afford. My check engine light is on constantly now because of the problem it has created with the emission control system. This was not the result of any actions of mine. I have done the maintenance to maintain this vehicle. Gm needs to be responsible for fixing this problem.
Vehicle remains running but shows power reduction. Check engine light comes on and stays on. You have to pull over, shut it off, press the arrow button on the steering wheel for a few second and restart. This happened on i35 at 70mph 4 times in 40 miles yesterday.
Tl*the contact owns a 2003 chevrolet silverado 2500 hd. While driving 60 MPH, the contact noticed oil leaking from the vehicle. The dealer stated that the oil pump created a hole in the transfer case. The dealer replaced the back half of the transfer case. The failure mileage was 62,438 and current mileage was 63,000. Updated 01-14-08. *kb updated 12/12/07.
Dt*: the contact stated the vehicle was started, ran for 10 seconds and stalled completely. The vehicle was not able to be restarted. The vehicle was towed to a service dealer who was unable to duplicate or determine the problem.
