Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“1st issue; in sept/2000 I wrote a letter to NHTSA about having to replace the cfi unit. From what I understand, the cfi unit has been re-engineered because of many failures. The oem unit could cause cylinder wall damage, fuel can leak into the oil sump, posible engine fire and shortened engine life. I feel GM should be responsible for replacing this unit at full cost. 2nd issue: my Blazer started peeling paint on the hood in 2001. Is their anything I do to get GM repaint my Blazer? …”

NHTSA complaint #806744, filed 1996-12“Recall 99i006000/ manufacturer's recall 99046; consumer is having a brake problem. Consumer had recall repairs done, and engine check light kept coming on. Dealer told consumer to drive it home because the computer needed to be reset. Consumer then found that there was a wire lying on the floor. Dealer forgot to reconnect it, and that caused engine check light to stay on. Dealers had to put back the old part for the brake module instead of the new part because consumer has to get the hydraulic brakes fixed before they could put new part in for the brake module . …”
