Chevrolet Suburban owners have reported 2 problems related to speed sensor (under the vehicle speed control category). The most recently reported issues are listed below.
At first I got a check engine light on with code p0430, O2 sensor lower bank 2, then bank 1. Replaced those two work for a week then rpm and speedometer gauge fluctuate up and down. I drove home from the airport one night and all gauge reading went all the way up. I was traveling on an interstate with a speed limited of 55mph and the reading in my car was over 120mph. Took to in shop, shop recommend I need speedometer sensor replaced. Replaced that, now all the instrument gauge jump up and down. Sometime all the way full sometime all the way down. Finally got tire of trying to fix it myself and took the car to the dealer and they found out it was a bad dash instrument and bad catylete-conveter. Thanks to chevy it cost me headache, guessing time, giving false reading and most of all thousands of dollars to get it fix right.

Brake failure at low speeds. Almost caused a few accidents (parking lots and coming up to a stop sign or red light. These incidents happened over several months. I had brakes, calipers and rotors put on to try and fix the problem. The problem started out once so often and around Aug. 2005 it happened everytime I drove my vehicle and took it to the dealer and had it repaired. Both front speed sensors were removed and cleaned sensor mounting surfaces. To me this is a safety problem. This is nothing I could prevent from happening. Defective material. I had an older Suburban before this one and never had this problem. It was still running at 190,000 miles.
