Latest MPV fuel system complaints
The idle air control valve on these vans is seriously flawed and is prone to failure which stalls the engine and puts occupants in peril at high rates of speed without power braking or steering. Once stalled, the engine can often fail to restart, leaving the driver unprepared and paralyzed to react. Background - approximately six months after purchasing our van used (2-3 yrs old / 30k miles), we began to experience significant issues with the vehicle stalling randomly after 6 months of owning. Unfortunately,...

the engine stalling was not a result of not maintaining an idle well on a regular basis. It was random and often followed by the engine running extremely rough, once the driver was able to restart (but then would go away completely undetected). I cannot stress how unpredictable the engine was over the year we experienced this intermittent stalling. Every 1-3 weeks it would stall and sometimes we'd be stranded 1-30 minutes before starting and running normally (no check engine light after engine sat and restarted. Light would come on when problems started and would cycle off once engine ran and computer checked sensors. Why the contact to the nhtsa? Real issue I have with here is that the van would randomly fail to idle and stall the motor when at freeway speeds over the year (6/2009 - 6/2010) this went unidentified. As a primary means of transportation in our household for four children (as most vans are), my wife refused to drive the vehicle starting in beginning of 2010 because of her experiences and subsequent fears after many close calls in which she couldn't steer or brake in a safe or reliable manner. The driver must shift to neutral (while at 70+ mph), and attempt to turn the engine over, to gain control again. Take action on this as it is far too common and dangerous to ignore. Mazda must be held accountable for the safe operation of these vehicles. *Tr
The dealer replaced the filler tube for filling up the gas tank. Every time I pump gas into the vehicle I get back splash that goes all over myself and the ground. I've been trying to get them to fix the problem, but the dealer and the manufacturer don't want to fix the problem. The vehicle was still under warranty when the problem started. They have replaced the filler tube twice and the gas tank, but the problem still exists. This back splash is dangerous to my health and the environment. I bought this vehicle brand new. The problem wasn't there when I bought the van. *Tr
I was on i-75 when I accelerated hard while trying to merge into a gap in heavy, merging traffic. When I took my foot off the accelerator my van continued to accelerate as the engine continued to rev at a high rpm. I stabbed at the accelerator with my foot to see if I could unstick it, but it only caused the engine to rev even higher - to full-throttle. I jabbed at it multiple times to no avail. I tried to lift the gas pedal with my foot by jamming it underneath the pedal and pulling it up, but it floated...

freely and continued to fall back to its full-throttle position. Although I was confident that the floor mat was not the cause of the problem I pulled it away from the pedals and, as expected, there was no effect. I was able to keep control of my van by applying extremely heavy pressure to the brake while shifting between neutral and drive. During that time I was still jabbing and lifting the accelerator with my right foot trying to 'unstick' the gas pedal. I was entering and crossing and overpass that was undergoing construction. Concrete barriers lined both sides of the highway and bridge where the emergency lanes would have otherwise been located. I had to maintain some speed, for fear of being rear-ended, while searching for the first opportunity to pull over. My vehicle was towed to the nearest mazda dealership where the mechanic was able to quickly ascertain that the screwing mechanism from an unsecured air hose clamp had snagged the throttle arm - the clamp attaches the hose to the engine. As I pushed harder on the gas pedal it further exacerbated the problem by locking the arm in a more wide-open throttle position. The clamp had been left unsecured from previous work done at a mazda dealership. According to the mechanic, this could have also occurred if the clamp had been secured, but not positioned out of the way of the arm. *Tr
Tl*the contact owns a 2006 mazda mpv. The contact stated whenever fuel was added to the vehicle it spilled back out. The dealer replaced the filler tube twice and the fuel tank one time since the vehicle was repaired and the failure continued to occur. The fuel continued to spill out on the contact. The manufacturer wrote a letter and a customer service representative should have notified him. The failure mileage was 38,944.
Car is running fine, and then engine stops. After setting for a minute or so, engine will start again and run fine for days ...Then the above recurs. Replaced idle control valve...No more trouble. *Tr
Mazda 2004 mpv with just under 68,000 miles has 3 fuel injectors(cel) replaced by local mechanic- 2 weeks later jerky misfires with cel required #5 coil replaced by dealership, less than a month later #4 coil replaced by local mechanic in town we were vacationing in-no cel, now same jerky misfires starting again a month after last replacement. Recent forum entries seem to indicate a growing problem of this type for 2004 mpv. Except for towing charges, expensive repairs, and inconvenience- no injuries. *Tr
Since new, hesitates between 40-50 mph, causing sudden loss of power, high rpms but no acceleration. Removing foot from gas van sometimes recovers. Has had transmission control module replaced as a result, then ignition coils were blamed and those were replaced one by one, sometimes more than once, then coolant temperature sensor went, now at 85,000 transmission went. Each event stranded my family by the side of the road and car had to be towed. *Tr
Dt*: the contact stated while depressing the accelerator pedal, the vehicle would not accelerate. The vehicle was taken to the dealership, where it was determined the bladder separated in the fuel tank and was getting into the fuel pump. The gas tank needed to be replaced.
The seat belts on my 1991 mazda mpv are simply falling apart. The fuel vapor separator does an inadequate job of keeping gasoline fumes out of the vehicle. There have been recalls on both of these items. When I took it in to the local dealer they only performed an inspection. Both issues remain unresolved. Besides not ever buying another mazda ever. I would like to see these safety issues resolved. *Nm
2005 Mazda 3 sedan has had the following fuel/stall failures over the last 6 months. 1St incident happened while driving on freeway, car stalled and had to pulled to side of road and restarted after several minutes and attempts. 2Nd incident, car was parked in owners driveway and failed to start (lack of fuel), 3rd incident car again parked in owners driveway and failed to start (fuel starvation). All three times the car was taken to dealership and nothing was repaired. Dealership service advisors claimed that...

fuel starvation/stalling could not be duplicated. The fuel starvation/stalling seems to happened randomly, but the risk of it stalling during driving is a very unsafe hazard. *Nm
Bucking and loss of power, noise coming from area near fuel pump until part failed completely and car would not start, or it was taken in for repair before complete failure to be replaced. Four fuel pumps have been replaced in 10 months of ownership of new car. *Nm
After driving 45 mph on blue ridge parkway for at least 3 hours, I was exiting onto a major highway. When I stepped on the gas, I had a loss of power that almost caused an accident. Could not easily recreate the problem, so I did not go to the dealer about it. *Nm
During accelleration loses power, hesitates, feels like its going to stall and smoke comes out of exhaust. Dealer has replaced fuel pump, problem got better for a short period but has begun to reoccur. No check engine light so they say there is nothing they can do for me. Two failed repair attempts - counting up to lemon law!
After refilling the vehicle consumer smelled fumes inside the car. Dealership was notified, but did not resolve the problem.*Ak
