#1 I was told that GM used calipers from a smaller car on the malibu thus causing the overworking of the breaks da da da...#2 FYI GENERAL MOTORS Çhevrolet Malibu
2000–2001 Malibu equipped with 3.1L V6 engine: an engine noise during the first few minutes after a cold start could be caused by too much play between the pistons and the cylinder bores. Have the defective pistons replaced at no charge before the warranty expires.
V6 engine: check for oil and coolant leaks at the intake manifold gasket after 80,000 km. Please visit the Investigations section of our site if you experienced this problem. This can be referenced at;
