 Traveling at speeds of 30-60 mph during any type of traffic (stop and go, freeway speeds, etc), my 2003 mazda6 will suddenly go into a safe or limp mode characterized by abrupt loss of power with no ability to accelerate. the rpms drop to between 1000 and 1300 and fluctuate quickly between the two numbers. i have had to quickly press the clutch, turn the car off and back on to regain normal function. when taken to a mechanic, the root cause was determined to be a defective throttle body. upon more research (including this site), this does not appear to be an uncommon issue for this model of mazda.

 Traveling at freeway speeds in ca on the san francisco bay bridge during evening traffic, my 2003 mazda6 suddenly went into safe or limp mode. this caused abrupt loss of power with no ability to accelerate, which almost caused a multi vehicle accident. when taken to a mechanic, the root cause was a code dtc p2135 for a defective throttle body. mazda admits 3 (three) versions of their throttle body for that vehicle defective with automatic discard if there is a mil with dtc p2135(per technical service bulletin no. 01-016/06 issued 05/18/2006 by mazda north american operations), and throttle body markings aa,ab,ba. mine is an aa. obviously mazda admits that these are defective, but only replaced them under warranty and my vehicle is not under warranty any longer. they call the new part an upgraded version. my vehicle has done this (safe mode) several times, so now it is parked until i can get it fixed (quoted price for repair is $714 from mazda dealer). these incidents creates an extremely dangerous situation and i feel very lucky that i was not involved in an accident when this happened to me, and luckily no one was injured, it could have been a very dangerous situation. i feel mazda has made a technical service bulletin admitting that this part is defective and it can cause danger and possibly loss of life. mazda needs to be forced to make a recall and replace these parts at no cost to the consumer. defective part - throttle body with markings aa, ab, ba mine is aa

 On several models of mazda 6's mazda has issued a tsb for the problem which is a defective throttle position sensor. i have read thousands of complaints by consumers. mazda has made a new part yet not recalled the old part. when this part fails you lose all acceleration power to the vehicle. the way to reset this is to turn off the motor and turn it right back on. i was driving on a two-lane highway crossed over the broken double yellow line to pass another vehicle when this defective part failed and i lost all acceleration. thankfully, i had just enough time to be able to allow the same car i was passing to pass me and i pulled off the roadway. the car worked fine for the rest of that trip it occurred again on the freeway in the fast lane. i contacted mazda corporate customer care they advised me that they were aware of the issue but had not issued a recall at this time.

 Beginning in 2006, my 2003 mazda 6 would randomly experience power failure while driving. this was both scary and dangerous. i would be driving, the car would completely loose power with no warning and all the lights on the dashboard would come on. i would have to pull over, turn my car off and back on, and then it would work fine till it randomly happened again. obviously loosing power at a high speed is extremely dangerous for both myself and the other drivers. i took it to the dealership many times and they were never able to determine a cause. i brought my car to the dealership over 10 times for this behavior. finally in august 2008, i was reading on a mazda message board that this behavior is caused by a bad throttle body. there was even a mazda service bulletin issued for it in 2006 (bulletins 01-016/06 last issued may 18, 2006). i called the dealership, had the throttle body replaced and have not experienced this behavior since. the service bulletin had serial numbers of bad throttle bodies listed on it, mine was one of them. i believe that this should be a mazda recall, not just a service bulletin, as dealerships do not even seem to be aware of the problem and it the car is extremely dangerous if the throttle body fails. *tr

 I purchased my 2003 mazda6 in june of 2003. since then it has been in the shop for mutiple problems. several recalls of course, but the first major problem came when the car was about 1 year old and my radiator seam at the bottom seperated. they replaced the radiator. when i picked the car up my air conditioning was not working, so i returned the car and the problem was fixed at that time. april of 2005, my car only had about 19,000 miles on it my air conditioning started blowing hot air. i took it to the dealer and the stated that my freon was low and charged it up. i asked how that could be with a car as new as this one and they stated, it was normal. for a car that is less than 2 years old?? last week, august of 2005, once again my air is blowing hot,particulaly when sitting in an idle position,works better upon accleration. i took it to the dealer and they stated the control fan module was bad and replaced it,which by the way had already been replaced with a recall. as of augusst 22, 2005 my air is still not working properly. we went on a short trip and were stuck in a traffic jam. once again the air would not blow cold while we were sitting. i know this is not right because when we first got the car, the air worked great. i am really frustrated with this car,i just keep waiting for the next thing to go wrong. i have also had to replace my braked pads and had the left front rotor turned. i think mazda owes us all of us that have purchased these cars and had major problems a big apology . and should replace these vehicles, which i know will never happen.

 While waiting in my car at the bank with the air conditioning on i noticed an odd smell and then the temp gauge started rising fast. i pulled to the side immediately and turned my car off and waited 30 minutes. i took my car in the next day and was informed my cooling fan control unit needed replacing, which they did. i had to ask for my invoice which was given to me. it is working fine now, but i find it odd that such a new car could have such a problem.

 Over a period of 1-1/2 hours, our 2003 mazda 6 quickly lost all acceleration power on 5 different ocassions while driving out of town on the highway. following a 'slight bump' the car went from 70 mph to 35 mph to 10 mph, quickly, regardless of pressure applied to the accelerator. getting to the side of the road in traffic going 70mph+ was in itself a challenge and after pulling to a complete stop the car began jerking fiercely. only turning off the engine completely was the system 'reset'. the mazda dealership hooked it up and determined the throttle body must be replaced for a quoted cost of $534.41 (macon, ga). the sensor itself, the likely culprit for this issue, is not offered or available for sale by mazda without its 'body', unlike countless other makes, which is outrageous, but the most disgusting part of this issue is that although there are a critical number of complaints logged about this issue, the tps has not been listed as a recall. the dealership stated they did not have to replace it since there were only 'service bulletins' listed and no actual recalls for the parts. they are very aware of the situation. from my own experience and my daughter's with this issue, i can guarantee that this has definitely caused serious injuries, if not fatalities, that just haven't been reported or possibly identified. i will continue to hunt down the sensor as i will not fall prey to mazda's 'racket'. the car will sit until i locate the part, or end up being parted out.

 Tl*the contact owns a 2003 mazda 6. while driving approximately 35 mph, the vehicle vibrated and hesitated without warning. the contact pulled over to the side of the road and the vehicle was towed to an authorized dealer. the technician stated that the failure was related to the engine, which was replaced. in addition, the vehicle would shift roughly from first to second gear. he experienced failure with the exterior lights and the window operating mechanisms. the vehicle was taken to an authorized dealer and a diagnostic test was performed. the technician stated that the aftermarket electronic components were possibly the causes of the failure. the vehicle was taken to an independent mechanic, who replaced the following components: alternator, battery, exterior lights, and four window operating mechanisms. also, the computer module, transmission, and air conditioner modules were replaced. the failure mileage was 85,000 and current mileage was 94,000.

 I drive a 2003 mazda 6s, which i purchased from bigger's mazda in elgin, il. this vehicle was purchased new from them. my area of concern involves the check engine light on my vehicle, and the performance of the vehicle when this light is on. on april 2, 2004 my check engine light appeared for the third time. when i operate my vehicle with the light on it performs erratically and unusual. the last time the light came on, i was pulling out into traffic, and my vehicle bogged down. in turn, the driver behind almost rear-ended me. while driving my vehicle yesterday, i went to pass a car on the expressway, and again my car bogged down. every time that i take my car to the dealer, i provide them with the same complaint. i have paperwork to show that i have taken it in three times. after a recent visit to my dealer, they stated, we have no fix for the check engine light. the light will always come back on. if you are lucky, our mazda engineers will have a remedy by august 2004 (today is 4/6/04). the check engine light is caused by a misfire in the fourth cylinder. what an awful response from the dealer. i am concerned about the safety of my car. i am also concerned about the other drivers around my car. after three visits to my dealer, i feel lost and helpless. please advise. *la

 I purchased my 2003 mazda 6s in october 2003. since i have owned the car i gets poor gas mileage on it (about 16-18 miles per gallon). i do plenty of city driving but i still feel that this is not adequate. even when i drive on the highway the gas mileage averages poorly. there is also a smell coming from the exhaust when vehicle is in motion. the vehicle also rev's up higher before switching from lower gears to higher gears. i do not 'jack rabbit' start or stop the vehicle. there is also alot of brake dust on the rims of the front wheels. acceleration is very poor. there is also a jerk when the vehicle switches from first gear to second. don't get me wrong i love the way the vehicle looks, which is the main reason why i bought the vehicle, but the overall quality has turned out to be much poorer than i had expected.*ak
