Two problems related to brake sensor have been reported for the 1998 GMC Yukon. The most recently reported issues are listed below.
: the contact stated intermittently, while stopping the brakes would grab. This occurred at various speeds. The contact cleaned the sensors and there is no longer a problem. There is a NHTSA recall, # 05v379000, regarding the antilock brakes. The vehicle had the same problems as indicated in the recall; however, it is not included in the recall due to the VIN. Updated 2/20/2007 - rust had built up under the front abs sensor which caused sensor errors.
While stopping at slow speed, my anti-lock brakes activated on my 1998 GMC Yukon causing me to narrowly miss an accident. The system would do this at least once a day with no warning. I had the vehicle repaired - the corrosion was removed from under the brake sensors. Months later I saw gm issue a recall on this issue but vehicle years were from 1999-2003 not including 1998. I called gm and they refused to cover my 1998 under the recall even though the parts are identical in the braking system between a 1998 and 1999.
