MAZDA5 4-cyl

  • 30,000 miles


At a full stop with my right foot on the brake, the car jumped (as if being hit from behind) and the engine began revving as if I had my foot pressing down as hard as possible on the accelerator. I had to put the car into neutral and turn the car off to get it to stop. This has happened several times since February at random intervals ranging from 4 months to 1 week apart between incidents and in all different types of weather. Mazda's computer is telling them that pressure is being applied to both the brake and the accelerator at the same time, and therefore they say they cannot come up with any other cause than that I am putting my foot on the accelerator at the same time as the brake. This is not the case. I video-taped the last occurrence. The car got up to 7000 RPM and the sudden force of the car jumping into gear actually caused the car to slide even though I had been at a full stop (this instance was in icy conditions). I video-taped the fact that my foot was not on the accelerator, but because my phone does not have a light on it, this was too dark to discern with the dark interior of my car. My husband has also been in the car when this has happened and has seen that my foot is not on the accelerator. The local Mazda dealer also rode with me to ascertain that I am not a two-footed driver. Mazda is throwing their hands up in the air because their computer will not produce a code to identify the problem, will not offer a rental car, will not offer to replace the car, and will not keep the car long enough to reproduce the problem (which they say is the only way they can identify it and fix it). I even asked them to keep the car the last time it happened until they could reproduce it, and instead they installed a black box device which basically ended up telling them nothing except that force was being applied to the accelerator.

Around 26000 miles, I noticed my 2010 Mazda 5 started showing difficulty shifting. There are 2 noticeable times when it occurs, 1) when travelling between 30-40mph and you remove your foot from the accelerator for 5 seconds or so and then depress the accelerator to increase speed, the car fails to respond until you almost push the pedal to the floor, and 2) when accelerating out of a turn or when traffic light turns green as you approach slowly, the car fails to respond when you depress the gas pedal to accelerate. I reported issue to dealer and the standard answer "unable to duplicate" was given and it was stated by the dealer that a transmission flush is recommended at 25K-30K miles for the Mazda 5. I checked the maintenance schedule for a 2010 Mazda 5 and there is no indication of any inspection or replacement of transmission fluid for the first 60K miles of the vehicle. I also researched the issue at www.mazdas247.com and found this is a known issue and that a transmission flush does appear to fix the problem. Most dealers charge $125-150 for a tranny flush and this is not covered by warranty (3yrs, 36K miles standard for this model). A car that fails to accelerate when you need it to as well as having to a significant service maintenance not recommended by the manufacturer appears to be an issue. Hopefully you have received other reports about this issue.
