There is a problem with the variable valve timing system causing reduced acceleration performance. The check engine light is displayed. This problem is exactly the same as the recall on mazda3 vehicles manufactured between july 2011 and november 2011. The car lost acceleration and a vehicle behind me almost rear-ended my vehicle. For some reason mazda is not recognising the recall on later models affected by the same issue. Mazda recall reference is 6511k. The recall should be expanded to cover additional vins

I purchased my 2012 mazda 3 one year ago (2017). I first noticed the issue about a month after owning my car. I turned on my air conditioner at first low, then all the way up, it felt slightly cool, but only as if my fans were blowing and nowhere near what an air conditioner should properly feel like. This was after letting the car warm up, and driving on back roads or highways as well as when parked. I brought the car back and the technician had some trouble figuring out how to fix it. The AC compressor was replaced, and yet I am still now dealing with a car that will not blow cold air! Only semi cool on the highest fan setting ! Also when accelerating and having the air conditioner on my car does not accelerate as well or feel as though it is driving as well as it does without needing the air conditioner on. My car really feels like it is working extra hard to put out semi cool air. I have had the air conditioner checked again and it says its not as cool as it should be. I need a resolution to this please.

More that one problem with this vehicle. 1) it starts honking while driving, instrument panel and interior lights flash on and off, the car will only make right turns and will not restart when vehicle is turned off. Yesterday, it did it once again immediately as I turned right onto the city street from a parking lot. Luckily there was another parking lot entrance on the right, so I pulled in, parked and turned off the vehicle. It continued to honk, flash interior lights and instrument panel and ignition would not work nor crank. I tried to restart the vehicle several times over a five (5) minutes, when it finally restarted and I was able to get the vehicle home without it happening again. This vehicle has done this several times and it will start honking in the middle of the night while parked and off for no reason. There are times that as quickly as it started honking it will stop, other times, I must go attempt to turn vehicle on and eventually ignition will crank and engine will start. I have taken it to mazda but they are not able to replicate the problem and tell me there's nothing they can do. I am worried I will not be able to turn one of these days and hit someone and get hit by someone else when the car decides it won't turn left. Not to mention if the car will not start while I am in a bad area and be harmed while waiting for the car to stop honking, flashing and refusing to crank and start. 2) when you put gear in drive, from either park or reverse, and take your foot off the brake the car accelerates and lunges forward without pressing the gas peddle. The first time it did it I almost hit a parked car! Thankful I acted quickly and reapplied the brake. Now I allow enough space, as if I driving a truck and am ready to apply the brake. Dealership states nothing is wrong with it. Mazda needs to take these matters seriously. But it's going back!!

In the morning of march 31, 2017 when I've proceeded to va 206 to the naval lab (25-mile speed limit zone), traction control system (tcs/dsc) indicator light suddenly lit up, and car stalled. I attempted to accelerated but received non response from the car. The car stayed around 20- 25 MPH. I pulled in the auto shop and turn off the engine. I re-started the car and the tcs/dsc indicator light was off and car behaved normally. However I don't know if the problem will happen again.

Cruise quit working, traction control light came on and shortly thereafter the check engine light came on. Then all the lights on the dash started flashing and went into limp mode. Car decelerated and I pulled over to the side of the road. Turned car off and then it wouldn't start. Waited about 10 min and restarted successfully with the check engine and traction control light still on. Drove another 70 miles going in and out of limp mode with dash lights flashing on & off. Took to dealer and replaced the angle (sp?) sensor in steering wheel. Dealer reset all codes and it's done it twice since getting car back, dealer can't figure out what's wrong. Have to go in and have the codes reset every time to get it back to running again.
