 Gm is conducting a recall on all subject vehicles build between may 1999 and october 14, 1999.significant changes were incorporated into production in early october 1999, and vehicles built after that date have lower warranty failure rates.the complaint and warranty data appear to support the effectiveness of these changes. gm made additional changes in november 1999, february 2000, may 2001, and february 2004.odi will continue to monitor this problem and will take further action, if warranted, in the future.for further technical details see the attached engineering analysis report.
