Instrument cluster shorts out and gear indicator goes blank. No message center information warnings are displayed. Part is defective and car makers should replace it. Not knowing what gear vehicle is in can lead to death if vehicle left in neutral and rolls away. GM needs to fix this expensive problem. Also 4L60E transmission on these vehicles fails and starts slipping because of defective sun shell and real piston seal. GM should recall all these bad transmissions. Warranty should have been for life. Why should such an expensive part to repair fail under normal use? recall ! both these parts fail when driving. All warning of vehicle conditions are sent to failed cluster. Vehicle was made in Mexico for re-importation and sale in usa and maybe parts suppliers in Mexico provided defective parts. Many people have suffered financial loss trying to fix these problems, lastly, the emission solenoid near the tank also fails. Vehicle may not pass emission.

The vehicle is a 4WD Suburban 1500. With 2 wd drive selected and driving at various speeds from 5 mph to 60 mph the vehicle will go into neutral. This has happened 7 or 8 times. Each time was in traffic which required illuminating emergency flashers and pulling to side of road. Every time presented a safety issue and was fortunate it didn't cause an accident. On one occasion I had just passed a semi on the interstate and had just pulled back into trucks lane when it occurred. Dealership could not detect a problem. The gear shift selector remains in "drive", the dash selector remains illuminated in 2wd and I get no messages on instrument panel message center. To troubleshoot I selected "auto 4 wd" on dash selector and operated for a week with no problem. I then selected 2 wd and the problem reappeared within 2 hours of operation. Once I stopped, I selected 1,2,3 and R on gear selector with no effect. Selected neutral and turned ignition off and then restarted with no effect (on previous occasion I had selected park with vehicle running and noticed a gear grinding noise so didn't want to do that again with engine running). Turned ignition off with gear selector in neutral and selected auto 4 wd and then restarted engine which took care of problem.

Binding noise in steering column, has been lubed numerous times while waiting for Chevy to issue a recall according to dealer. This vehicle is driven under 15000 miles a year.

Transfercase on suburuban began to leak around 80K miles when you put on lift you'll see little pin holes in the transfer case. This is caused by a faulty design where the pump rubs a hole from the inside of the T-case to the outside. Numerous companies have made a mod kit to address the issue which GM has not. You can put a temp bandage on it using jb weld but the case will need to be replaced.
