Good Morning All,
I am new to this forum and this is my last resort..
Have a 2008 Suburban 1500 LTZ with 80,000 miles on it had no issues, Originally from Upstate NY, then moved to Kansas for work about three yrs ago, about a year ago suddenly out of the blue all this starts happening
1) while driving, all these warning signs starts flashing on the dash like service Traction Control,
Service Stabilitrack,
service suspension,
the speedometer suddenly drops to zero even though car was and is at about 55 MPH,
and that underscore or dash that you see underneath the PND21 disappears so you have no idea where in transmission are you ? are u in Drive or Neutral and so on ,and it starts shifting gears Real hard..
and the locks start going up and down by themselves,
Took it to local Dealership and have been taking it to them, they try and clear the CODES , charge me money have roughly spent about 600-800 Dollars on this problem since oast year but problem remains..
The service Manager has seen this and says " I think your car is possessed " nor granted that this was funny but did not made me feel good coming from the Mouth of service manager!!
then the other day called Northstar and spoke to "area specialist " whatever that is and He has also NEVER heard of any such thing!!!!
I am disgusted to the point of selling the truch and never buy chevy Truck BUT up until all this start happening I had no complaints at all...
Can someone PLEASE help???

 

Yeah my wifes suburban dash cluster did the same thing. I replaced the entire cluster and problem fixed.

 

Thanx Mike for your response..
what is a dash cluster and how much will that set me back?
and what do i tell the dealership??
Thanx Much again

 

The dash cluster is where your gauges are (gas, speedo, temp, etc). I think i paid around $200 for ours but i got it online on ebay and installed it myself, the only thing is the mileage is different but i dont care about that but your dealer can change the mileage back to what yours was originally if you want them to.

 

MasoodKhan,

I am sorry to hear you are having this concern. We can certainly reach out to your Chevrolet dealership on your behalf. Please private message me your name, VIN, phone number, mileage, and dealership name. Look forward to hearing from you soon.

Thanx and how do i private message you Sir

 

On my 01 I ran a new ground wire for the cluster and that solved it for me. Others as they have said had to replace the whole cluster.

What dealer are you taking it to? Near Wichita or otherwise?

 

Thanx hicksvilleshick,
am out here near Olathe, KS the dealership is Lang Chevrolet in Paola, KS..
Spoke to them this AM and left my truck and asked them to do Run a new ground wire from cluster as you suggest, lets see...The servive manager did not appear too convinced but agreed to try it, Replacing the Dash cluster he says will set me back about 600-700 .
Keeping my fingers crossed, will reports back to Y'all..
Thanx so Much for advice,

 

I have been fighting with this issue with my Suburban for about a year and I came across this video today and it seems to have gone away. I hope it helps.
