Now that I have traded the Malibu for a Honda, I thought I would post some info before deleting it from my comp. My two biggest experiences/complaints with the car......
Factory rotors are too small for the car (LS V-6)..replace with larger rotors or atleast use quiet stop brakes instead of metallic or semimetallic. The factory metallic pads really chew up a rotor quickly and tend to glaze. (I replaced the factory rotors twice on this car and was close to needing a third set. 171,000 miles)
Intake seals will leak and is not a cheap job.. (I replaced these twice and it needed a third set when I got rid of it)
Other items replaced in time frame owned: Alternator / Water Pump / Tensioner Pulley / Belt / Fuel Rail- Injector Seals / Thermostat / Several sets of Tires / 2 Batteries Also needed tires and struts when I got rid of it. The Pleather (Plastic Leather) of course had cracked revealing seat foam in several spots.
Overall not a real bad car and served us well.. The car never burnt a drop of oil. (Havoline 10w-30) Intake Seals on this 3.1 V-6 motor are the biggest pain..with brake repairs a close second.
I personally wouldn't purchase another Chevy V-6, with the exception of the
4.3 Vortec. (which I had two of those in other models)-------------------------------
Common Problem Solutions: The # 1 & 2 blower settings stop working. Order a replacement resistor and replace the old one.
Rattle noise coming from behind glove box when the car is crusing. Need to brace the blower box/ducting near the passenger side floor. Passenger can press toe of shoe up and in to see if it stops in your car.
Lost partial function of radio, many stations won't come in. Lift the passenger side carpet near the kick panel and press the antenna coax connectors back together.
Center console glove box cover catches when opened and slowly peels the top off. Reglue the seams.
Alternator slowly dies and doesn't show up as a problem until the battery wouldn't power the car or with the lights on when stopped at a light. Replace alternator.
Gas guage flips backwards / gas gauge now doesn't work. Use paper clip through the trip knob to flip the needle counter-clockwise.
HTH Someone.
