Everything below is an owner-reported complaint submitted to NHTSA about the 1999 Chevrolet Medium Duty, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

I HAD A MAJOR TRANSMISSION FAILURE DRIVING HOME FROM WORK. NO WARNING, NO NOISE, NO INDICATION WHAT SO EVER. VEHICLE HAD TO BE TOWED FROM HIGHWAY AT 2AM TO REPAIR SHOP. UPON INSPECTION BY THE REPAIR SHOP THEY FOUND THAT THE TRANSFER CASE FAILED AND CAUSED THE TRANSMISSION TO ULTIMATELY FAIL AS WELL....THE TRANSFER CASE PROBLEM WAS FIXED AND THE WARRANTY COMPANY ON COVERED MINIMAL COST....THE TRANSMISSION WAS FIXED AND THE WARRANTY COMPANY DID NOT COVER AND OF THE COST...LEAVING ME WITH A BILL OF OVER $1600.00!!!!! AFTER MISSING TWO FULL WEEKS OF WORK FOR THIS ISSUE I STILL HAD TO INCUR THE FULL COST OF THIS REPAIR. IT CLEARLY STATES IN THE WARRANTY CONTRACT THAT THESE REPAIRS SHOULD HAVE BEEN COVERED. PLEASE INFORM ME IF THERE ARE ANY RECALL ITEMS THAT COULD HAVE CAUSED THIS TRANSMISSION TO FAIL. *TR
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
