One problem related to ignition has been reported for the 1998 Mazda B4000. The most recently reported issues are listed below.
I have had a head gasket replace on this 1998 Mazda B4000 within 61,000 miles. The first head gasket replacement was 1-21-2008. Now the same thing seems to be happening at 78,100 miles are there any issues with this model? I only drive the truck to work and back which is only about 5 miles from my home. Also the front end suspension makes a loud squeaking/popping noise when you turn the steering wheel or hit a rough place in pavement. The "key in the ignition" buzzer keeps dinging after you take the key out of the ignition.
