I own 2 98' Chevy Malibu's and each one has had the same problems.
1. Short in brake lights.
2. AC temperature control switch malfunction turns on and off in both cars. 1 2 3 blower setting does not work on both cars and only has a fuse for setting 4 and 5.
3. Cheap Chinese metal used in brake rotors.
4. Had to 4 coil springs break on both cars because of Chevy using cheap spring steel. After replacing the complete strut assemblies I still have a lot of noise every time I hit a bump.
5. ABS light is displayed in both cars even after replacing both hub assemblies.
6. Horn started going off for no reason. Unfortunately the horn and airbag assembly are combined and very expensive to replace. I just rerouted to horn to the dash without disconnecting the airbag and have had no further problems.
Over all the car is O.K. The problems I've had have been forwarded to the GM engineers because I feel these problems need to be addressed. Weather they listen to me or not is the question. Thankfully I am an automotive service technician and all the repairs I've done myself. Here's a little advise, instead of purchasing brand new parts for these cars try to get them second hand from junk yards. You'll save a lot of money.
In the owners manual for a 1998 chevy malibu it says if the ABS light comes on then just turn the car off and turn it back on again then the light will go out. It appears that this is a common occurrence. As long as the ABS works this is not an issue.
