1998 Mazda B-SeriesSuspensionEngine & coolingElectrical system

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. *Tr

1998 Mazda B-SeriesEngine & cooling

Throttle sticks wide open on my 1998 mazda b2500 truck. Only recourse is to turn engine off to slow down. Have had it in to mazda shop twice for this problem. First time under warranty, could not find the problem second time, mazda says not covered under warranty, even though they had a tsb for this problem. I don't want to be a fatal statistic, because of yet another vehicle manufacturers failure to act. *Tr

2002 Mazda B-SeriesEngine & cooling

Engine cooling system had internal corrosion which caused heating failure (thermostat). In new hampshire when the temperature is at or below zero, the risk of freezing to death because the car will not heat properly could have its consequences. In order to correct the problem, the engine had to be replaced (used engine) at a cost of $3000.00 The problem was caused, most likely by incorrect antifreeze installed in the engine. This was done either at the factory or the new car dealership when the car was preped for sale. *Tr

1998 Mazda B-SeriesBrakesEngine & cooling

Tl*the contact owns a 1998 mazda b2500. While driving 50 mph and attempting to decelerate, the contact must place the vehicle into neutral and then turn off the ignition. The vehicle's engine overpowers the brakes. The contact feels that this is a safety issue because the vehicle should be stopped by applying the brakes. In addition, the throttle sticks and remains open. The brake failure has been occurring for the last eight years. The vehicle has been taken to the repair shop three times regarding the failure, but no failure was identified. The failure mileage was 35,000.

p225/70r15 100s. This model was not included in the 2000 recall, although I recently learned the highway safety board found these tires to have more complaints then the at and atx that were recalled. 3. I too had problems with the oil pressure not registering until the vehicles was warmed up after traveling a couple miles. Dealer said I had to replace sending unit which they didn't have in stock. I removed old sending unit and turned over engine until it blew oil out the post the sending unit goes in, and its been working fine every since using the same old sending unit. 4. The brake light on top of cab, started leaking water into cab around the gasket, so I had to silicone around gasket to stop leak. 5. Had problems with transmission not shifting and would go into neutral. This happened on interstate doing 70 mph. Pulled over to shoulder and after trial and error, found the only way vehicle would move was to put it into drive 1. Dealer said sensor was bad in transmission and replaced, and no problems since. 6. Transmission does not shift properly when traveling up a hill, especially if pulling a trailer, even when trailer is empty and there is a loss of power. The engine rpm gauge shows the engine running at 5000 rpm and transmission will not shift until you get to top of hill and start down other side. *Tr

2004 Mazda B-SeriesEngine & cooling

Since february 2005 I have had my mazda rx8 serviced for engine noises, deceleration problems, stalling problems and restart problems. The vehicle begins to idle rough and just stalls out (twice in the middle of busy intersections with oncoming traffic-life threatening situation) and cannot be restarted. The vehicle has to be towed in to the dealership for restart. The pcm has been reflashed several times, plugs have been changed and the problem still persists. I am afraid for my life and will not let anyone...

else ride in the car with me. The service department at the dealership is aware of the life threatening situation and I want to know if I have any recourse in getting mazda to buy back a car I cannot drive. My luck will run out in this vehicle and not only will I be injured or killed, but so will other drivers (oncoming traffic or traffic behind me). I have called mazda headquarters twice about this recurring problem and am awaiting a call back from the second phone call into mazda. Apparently they don't feel it is as bad as it is. *Nm

While pulling into my driveway, I was braking to park while the automatic transmission was still in drive. Suddenly, the engine started to rev on its own, while my foot was on the brake. The tachometer started reading in the danger zone, and the engine was revving out of control. White smoke started to come out from under the hood. I was able to put the car into park and turn off the engine. It was quite a frightening experience.

2 Occurances in 3000 miles of engine loosing power, then starts to buck above 3500-4000 rpm. This first happened on the freeway and it was difficult staying out of the way of traffic until I could exit. The second occurance was after I had exited the freeway onto a 2 lane. I then drove 30 miles to home. Both times it was ok the next morning. Dealer cannot replicate the problem.
