99+up common problems

[Huck]

Ok let's list them---
1- Steering column vibration mostly noticed going slow --off road or in parking ---the column intermediate shaft is fluted with grease taking up the shock---it gets squeezed out. There is a factory bulletin to either repack or to "stroke!" the unit---what a BS fix this is but it works for a while.
2- Windshield noise pass side---from a bug shield changing the air flow!! Tape, caulk windshield to molding or take of the bug shield.
3- Premature front brake wear---factory bulletin for "northern states!!" ie the antilock sensor looses it's ground path due to salt-rust getting under it's mount to the spindal housing. factory bulletin recall---get them to replace the pads if you can.
4- Brake drag noise from the drivers side rear---the parking brake "horse shoe" unit is dragging on the drum and wearing out. Factory bulletin replaces the spring holder and possibly the horse shoe assembly but only on manual shift trucks!!!! how is that for another BS fix from GM?
OK guys, add some more as these trucks are full of BS GM issues~~~~

Welcome to GM trucks and SUV's from 1995 and up. My last 3 drove me crazy with leaks of every type.I finally solved my "newer" GM leaking problem by not buying anymore!

After reading through this thread I'm only more disappointed with my 2000 4.8/4l60E Silverado 4x4. It has the "towing package" with 3.73 gears and whatever else that entails. This thing can't climb up a slight grade without downshifting every 30 sec even with my small utility trailer loaded down with a Murray riding mower. I know only its a 4.8 but they claim 285 horse or something? It has no torque whatsoever. I miss my 95 Z71 5.7 TBI, it had nothing above 4000 rpm but had lots of grunt down low and could pull my boat up a hill easily. Not to mention the annoying column clunking, piston slap, burnt out radio buttons, $1000 abs pump repair, overdrive shift solenoid, blower motor resistor, noisy ac compressor etc. This truck is a weak, cheap built POS. Now I hear you guys saying the 07 ups are worse?? I've always had Chevy trucks but am ready to throw in the towel on these newer ones. Lots of you say you won't buy another but tell me what new truck out there is worth buying? I'm tempted to cross the line and go with a F150. At least the 5.4 has low end torque, that is what a truck motor is supposed to have right? I know the Chevy LS series engines are screamers which is great for a Vette or camaro,but what good is that in a truck?

[michael bustamante]

before switching to the dark (ford) side let me fill you guys in on some common problems for f-150,and up along with suv`s
ball joints constantly go bad
trannys slip
rear ends go out and need rebuild
v8`s pop the spark plugs out of the head due to threads stripping. (head replacement)
deisels. the egr cooler leaks
window motor/regulators go out in all 4 door windows.
these are the ones I can just think of off the top of my head.

[truckdude239]

rear mains leaking
i've seen them at work with 3k mile ont eh trucks with rearmains leaking

[67ChevyRedneck]

4x4 dash switch

CSK

[66truckin]

I had an 07 sierra classic and it was flawless for the 17k miles I had it. It was too big for the wife to drive so we traded it off on a car.

[Huck]

Forgot about the stupid faulty 4x4 switch.
The tow-haul switch in the shift stalk fails due to inadequate wiring into the column.
And the worst---and I have had 3 99+ trucks=5.3V8s and every one had the engine ratteling within the first 30k miles--sounds really bad in the cold butttt---they do run forever! Strong engines but one would think they could fix the stupid ratteling~~~.

[Slammed67]

Based on my truck....

• Gauge cluster power supply went out.
• Replaced fuel pressure regulator.
• A few of the radio/climate control button lights are out.
• Sticking accelerator pedal caused by dirty throttle body.
• Rain leaking into driver's side of cab. Ended up being the seal around the cab vent on the back of the cab.
• Driveline vibration, usually felt at low RPMs under load.
• Leaking water pump (or seal) that I need to fix.

This is the only problem Ive seen on my 04. Other then that its VERY solid. My dad had a 02 and never had any trouble with it... put 110k on it. Did have the "bug shield" noise after installing a bug shield, but I wouldnt call that a problem lol. Now he has a new style 07 and no issues with it either.


Never heard of any chevy truck with bad rear mains... or water pumps.

Can you explain what the symptoms of your problem was/were? And what the solution was??

On my '06 it seems I have been having a beech of a time regulating the temperature; if I have it at, say, 3/4 the way up and it I push the switch down slightly, after a few minutes it starts blowing cold. This is still way up in the red (hot) area of the control.
If I then nudge it up ever so slightly, after a few minutes it is cooking me out again???

[Houston54]

The flap that directs the air flow to either the defrost vents/dash vents or floor vents is controlled by a servo which goes out. Happened on my 03 Z71 but the dealer covered it. I believe they mentioned it would have cost me about $250 to repair.

Other problems are the fuel pump. If you have trouble getting the engine to start when you have less than a 1/4 tank of gas it is a symptom of the fuel pump darn close to giving up the ghost.

Found a whole bunch of mud and debris in the gas tank when it was dropped to replace the pump.

The dashboard ABS light and parking brake light coming on and staying on with no codes is also a common problem.

From my own experience regarding electrical issues I would check all the ground connections especially the one on the top rear passenger side of the engine block.

[67ChevyRedneck]

I've fixed the tow haul switch on mine. Easy fix. I need a new 4x4 switch. Just haven't changed it. It has a slight CSK but Mobil One just about kills it and it's not noticable in spring/summer/fall. I've put over 50K on my truck, had 66K when I got it, it has new tires (last set lasted 40K+) and new Bilsteins, still has the factory pads and rotors, but need to be replaced soon.

I'd buy another one of these trucks in a heartbeat.

[Huck]

My 99 had a coolent leak somewhere in the back--couldn't find it but did put some radiator stop leak into the system @ 140,000 miles. Sold it without a leak @ 188,000 miles.
Oh yea, there is that issue of cold air coming into the pass floor heater --that coating the foam rubber seal around the air box is supposed to fix---.
I certainly would not pay $25,000. plus for another new chevy truck. Especially when they wouldn't even sell you one with a 5 or 6 speed manual!!!! They can go chapter 11.

[Palf70Step]

So far the only one I have noticed on my 02 is the steering column clunk. But I have the el cheapo model, so no fancy stuff on it to break. Seems like all the GMs have the clunk since about 2000 year. Mine wife's Bonneville had the same issue.

[D13]

2 pc driveshaft failure/vib at low miles.
General rattles
Window regulators
water pump
#7 injector plugging

[kookykrispy]

Mine had the common problem of the odometer/drive position indication going dark... intermittent problem. I found a guy on ebay who sells the repair service for $100 + shipping. I'm currently driving around with no gauges at all because he is fixing them and will send them back soon. He has 100% positive feedback and instrument clusters is all he does it seems. I've got my fingers crossed!

Also:

-Problem with power windows only go to the right, but not left or up or down. I replaced the switch, but that was not the problem... so now what? I'm not sure.

-The driver's door seal is noisy. It lets the wind in at speed. On my list to replace the seal.
-The rear passenger side pop-out window no longer closes properly. Very noisy above 45-50 mph. Very annoying. I understand there is a fix for this by putting a sheetmetal screw through the hinge into the metal of the body.
-Rattle from the glovebox latch
-Rattle from the center console above the CD player.
-Keyless entry is 'lazy' you need to press the button on the key fob multiple times to get it to unlock... this is with a brand new battery in the fob.
-Seatbelts are twisted up and I don't know how to untwist them.

All minor issues... other than that its a great truck and I got a pretty good deal on it. I like the 6.0 engine and 4L80e trans. Its got alot of power and I also like the lines of the silverado bodystyle. Its spacious and very comfortable inside. For a 3/4 ton, it rides alot better than my old f250. I have the LT package with power heated leather seats and they are not loose and work great. I have only owned it for a couple months. It has 111k on it.

Huck, On your cold air coming in, how did you say you fixed it? We just did a trip and my wife really felt a draft on that side. I did too for that matter when she was driving. Is it an easy fix? Thanks in advance..

99% of the time the cabin air filters (2 of them) are very dirty and need to be replaced. the fan is on the up stream side and forces air thought them. when the filter is dirty the air bypass (due to the plastic and the seals letting the cool outside air into the inside on the pass foot well area. replace the 2 filters and you will haved fixed the cold air issue.

My '99 too!

My ABS module died a long time ago. I just pulled the fuse meaning to fix it, but it's been like 4 years now LOL.

Fuel pressure reg died.

And I think the water pump gasket is leaking. These trucks are notorious for that one.

Not bad considering I drive it like my momma stole it and I don't do much more than change the fluids in it. And it's almost got 100k of 98% stoplight to stoplight driving!

(Of course, now that I said something she will die.)

[cheyenne402]

Piston slap especially on cold start--I bought the truck from my Dad--who bought it brand new

2000 Chevy 2500HD 4x4 6.0 litre

He took it to dealer, they said "it is normal"--GREAT
