 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.

 The vehicle acceleration cuts off and the dash board lights are all on. you will have to shut off the car and turn it back on before it will work correctly. dealer said their diagnostic did not show any throttle sensor errors but my scan tool did.

 Car experienced unintended acceleration in stop-and-go traffic (0-30 mph) on 9/4/11 and 9/7/11. tachometer needle was bouncing between 1 and 3. car accelerated, and rpms increased, while on a level surface, without the gas pedal applied. car fought against my efforts to slow down by breaking. car stabilized upon reaching 40 mph. on 9/7/11, the mazda dealership attempted to correct the problem by cleaning the throttle body, but the intervention failed to correct the problem and it recurred on 9/7. this is a serious complaint with a high risk of injuries or death. mazda owner internet message boards describe this problem repeatedly. please investigate and mandate that mazda identify an immediate correction to this dangerous problem.

 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

 While driving home from my chardon, oh office on either aug 5 or 6, 2009 at 35 mph my car's rpm needle started jumping and the car's gas pressure felt like it was hicupping. the rpm needle jumped from @2 to 4 twice, then the car started steadily accelerating in speed. the brake pedal at this time felt hard and the car was fighting against my attempt to slow down and the rpm's were still trying to accelerate. i imagine if i pushed on the brake and the gas pedal at the same time, it would simulate the way it felt. i also have a manual shift mode on my car and used it to more effectively slow down (vs using the brake) but at the same time the car was still trying to accelerate, but couldn't because i was in a lower gear/manual mode. and i remember while in manual gear 1, my car was lurching me back and forth in my seat as i drove through my neighborhood to get home, and my foot was off the gas pedal! on aug 12th, 2009 i mentioned this event to a mitsubishi dealer's mechanic (friend of my father) who was replacing my power steering line, he took a look at my car but said it seemed fine. my husband has been driving that car since that event, because i am afraid of it happening again. the car has not done this while my husband has been driving it. not to sound like an oddball, but if i didn't know better i would have said my car was acting possessed, like the movie christine. i have to think that there is some correlation to what my car did and what is going on with toyota. my husband is an electrical engineer and he used to work for grob systems, who does engineering for multiple automobile manufacturers, and i wonder if mazda has some same system in their automobile's as toyota and if it was engineered by the same supplier. i would swear on a bible that this happened to me with my car. (my husband left grob to move to cleveland and marry me). it sucks having this car now, it is paid off, i'm afraid to drive it, and i don't want to sell to an innocent stranger. *tr

 Tl*the contact owns a 2003 mazda 6. while driving approximately 20 mph, the contact applied pressure to the brake pedal several times before the vehicle slowed down. the vehicle accelerated without the accelerator pedal being depressed. there were no warning indicators illuminated on the instrument panel. the vehicle was taken to an independent mechanic and it was concluded that the failure was related to a defective throttle; however, the vehicle began operating normally after the diagnosis. the technician recommended that the vehicle be taken to an authorized dealer. the vin was unknown. the failure and current mileages were 81,000. updated 10/16/08. *lj

 Dt*: the contact stated that the vehicle accelerated on its own and on many occasions while driving 55 mph. this occurred even while applying the brakes. on one occasion, the vehicle almost hit a pedestrian. on another occasion, the vehicle ran through a red light. the vehicle was taken to the dealers who determined the problem was pertaining to the throttle body. the vehicle was repair however the problem persists.

 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

 Was left stranded when check engine light and at light came on. car would not accelerate above 20 mph and had some jerking. had car towed in. service dept replaced throttle body and sensor. car still repeatedly has a jerk/hesitation when holding steady between the speeds of 40mph and 50mph. have brought the car in three times for the jerking/hesitation and the service mechanic does not know what else to do. they tried redownloading the computer which worked for about 1 week and then the jerking/hesitation proceeded. my service dept has spoken to customer service of california and they say they have not heard of any of these problems with any other mazda 6's and they have no idea what it is. i have also experienced a water leak in my vehicle about a month after i bought it which flooded my whole passenger side. carpet had to be replaced. my brakes have a squeaky, grinding noise when turning. my back seat seams are coming unsewed. will have to get the fabric replaced. my question is, what's next? i have already recieved legal advice and my lawyer thinks i have a pretty good case. if nothing can be done, then why not replace the vehicle. i am fed up with spending my time at the mazda dealership. i bought a new vechicle to stay away from mechanical difficulities.*ak
