2007 silverado Had it 12 months bought new 5.3L auto. Been in shop 8 times for vibration and noise problems at 1500 and 2000 rpm, at 1500 rpm I shift down so I just stay in 8 cyl just to avoid noise. Got the runaround at first then they handed me a bulletin #06-06-05-001B that states vibration and noise is normal when engine is in 4 cylinder . I belive thats their new way of repairing problems just write up a bulletin. I was also in for a vibration at 60 mph (noticed mirrors shaking), they replaced tires seems to have worked. Been a Chevy man since first truck in 87 very dissapointed on this one. |

I bought a 2007 Silverado Z 71, V8 5.3l with fuel management system, crew cab, last year and as soon as I put about 5000 miles on it a vibration started. When I come to a stop and the RPM drops to about 500 there is a vibration and it's not a constant vibration, it's an on and off vibration, at times it's more on than off. I read on-line that changin the stock spark plug wire with a Taylor 8 or 10mm wire will help, and at the dealer they told me that if I do that I will void my waranty. Has anybody else experienced this problem, or do you know how to fix it? Thanks.

Replying to: cata11 (Dec 03, 2008 2:52 pm) As far as the dealer voiding warranty...who did you talk to at the dealership? And would they put that denial in writing? I seriously doubt it. Plugs and wires are consumable items and are covered under the Moss Magnuson Act which prohibits the manufacturer from forcing you to use their products by voiding your warranty. Since it seems to be an idle problem, you might also want to check/clean your idle air controller. |

Replying to: sedaman (Oct 21, 2008 8:02 am) I'm from Quebec Canada, and have a mix of steering/vibration/wheel problems with 2005 sierra 4x4. have been hearing clunky sound from left front wheel and rough ride since 20,000miles Dealer couldn't or wouldn't identify the problem. Then had the lube job done, then some sort of column repair and still not up to par. Then went to an independent shop where they found that the bushing for the left side torsion bar was totally finished. Last night started to get a serious grinding noise from the same area, perhaps a bearing or CV joint, but I suspect it is all related. Some serious flaws going on here. Has anyone else checked /and or had torsion bar problems? Also, limited slip doesn't always work Frustrated and pissed off |
