Over the years, we have noticed common issues with this generation of Bonnevilles. Below, the topics are listed alphabetically, with a Miscellaneous section at the end for...well.....miscellaneous stuff ....or problems that were noted as being not common.
Bubbling Hood:
Symptom:
Paint bubbles on hood due to an incompatible primer on the aluminum hood of the 00’s. 2001+ used a better primer to prevent this.
Solution:
Strip and redo: Unfold the front seam, mechanically remove all material down to bare metal, reprime, and paint.
Note:
It should be noted that this is not a GM only issue. Ford had a similar problem on their higher end trucks that had aluminum hoods, during the same period. (98 to present) Also, one member’s ’01 did have this problem.
