Has there been a recall on fuel lines

This is all the time

Bought as new truck and never had any accidents or cause for failure.

When I first started the truck I was able to switch from neutral to Auto 4WD. When I shifted into reverse I got a grinding noise from the encoder motor and the truck wouldn't go into reverse. I was able to start the truck in Neutral and put it in Drive, but not reverse. I get the grinding noise. Now none of the lights on the dash come on and it won't shift into 4wd

Water getting in the cab after a hard rain

new rear end in the Avalanche now the darn thing won't go in drive it barley reverses now hen I drive I have to go through the gears starting in 1st then 2nd all the way up to third gear I don't know what's up with it any body got the slightest of clue I would really appreciate the help don't know if it may be the torque converter or the 1-2 solenoid I heard there's a fuse but I can't find it anywhere heck I don't know so I would really appreciate it guy and gals for any info on this problem

Replaced knock sensors. Started fine. Did not correct slight misfire. Was pulling plug wires and injector wires to isolate the cylinder. Slipped and broke the heater hose off the core. Sprayed me in the face. replaced fitting and hose. added coolant. hosed off the area with water... Now the thing will not start and run. Has 45 psi fuel pressure at the rail. Will run on starter fluid.

This is a on going problem while im driving. Feels like it's swaying a bit.

under the dash passenger side sounds like a flapper opening and closing constantly.

fuel gage, speedometer, tach, temp, volts gage not working

When I drive there is no tension on the steering . I feel like the front end is always on ice. This year of Avalanche has no steering wheel position sensor.
Are all 2003 like this

It has been difficult to switch between 4 low 4 high or 2 wheel drive for about a year. It would do it but it took many attempts before it finally clicked. Now its in 4 lo and when you hit the button you hear clicking then it just stops and stays in 4 low. I don't have any codes or problems showing.

drive ? Truck has 66k

We think it has to do with idler or pitman arm. When we took it to a chevy dealer, they said they werent bad, but starting to wear. They had no idea about the noise. It happens mostly on hiway driving and seems to diminish when we let off the gas. It is a rapid "tat-a-tat" noise.

I have hardly used the 4 wheel drive on the truck but since the weather has got real bad I have been using it. Now it makes a really bad scratching grinding noise in hi and low range.
2 wheel drive doesn't make any unusual noises thank god but I think there might be a bit of a problem here. I think the from dif has lost all its oil some how, how do I check and refil it and what weight oil should I use?

I just got a 2003 chevy avalanche a couple days ago. This morning on my way to work I was merging onto the freeway and when I looked down at my speedometer it said I was going 120mph. I knew something was really wrong so I started gauging my speed off my tachometer and the cars around me. About 45 minutes into my hour long drive to work my tachometer stopped working properly and then my oil pressure gauge stopped too. My truck believes that I'm going between 45-60mph at a dead stop and according to my tachometer 5000rpm is actually 0.

After I got to work I googled the issue and found out that they did a recall from some different blogs. I cant find the actual Instrument cluster recall number or anything anywhere but what I found on the blogs says that its 7 years or 70k miles. My truck only has 58,200 miles on it.

So my question is will they still honor the recall or are they going to make me pay an arm and a leg to get this taken care of and does anyone know what the recall number is?????

I can pull out in 2wd but want stay its like it goes to neutral but the button says its steal in 2wd so I have to run it 4wd

Is there a recall on this problem? And if not how to fix it and a shop near area code 77070 Houston tx. And what is the cost?

I was told that the instrument cluster needs to be replaced. Is this an expensive repair or is it something I can do myself without being in a garage?

I have the "service 4wh. light" also. intermittent at first. tried messing with the selector sw. and then read it out with a meter. not the problem. then i got code "U1026=Loss of communication with auto transfer case controller" but the relay, once it starts chattering, won't stop until the battery dies or until i pull the 4wh. dri. fuse and the ATC fuse (could have been BTSI fuse (been awhile) before the relay would stop chattering and the shift motor (i assume) trying to engage. The battery has been out of the truck for awhile. ps, i'm not sure how many mies are on it

driveshaft is tooing and I have to change the tailend on. the transfercase

I pulled my trans filter and put a new filter and new oil in it what is the chances it will only last a short wile or will it even be worth the time and efort

my wife was driving and she said all of the sudden the truck acted as though it was in neutral. I got home and started it and it drove forward and back and then it quit again. the next day was the same thing but if in shut it off and restart it right away it still acts as though it is in neutral.

I've had my truck sitting in the garage for 3-4 months and one day I decide to charge it and it turned on and i took it around the block to warm the engine. after 30 minutes of driving , I park it in my drive way. I try turning it on again and it completely died. any suggestions?

I thought it was the steering wheel position sensor but I don't have one.
Could the steering box cause this. Took a 2010 for test drive steering is stiffer and feel like I have control of truck.
