Car won't start due to PCM/TCM lost communication.

I purchased this vehicle for my 16 yr old daughter 1 yr ago. The car has a clean carfax and has had no accidents. Upon purchasing the car the headlights continue to burn out. Taking it to a Mazda dealership i learned the headlight assembly unit was melting. I had to purchase 2 used headlight assembly because new from the dealership are 1,000 a piece. 2 used but perfectly working headlights were installed and within a yr the headlights had burned out again. I went to change the bulbs only to learn the headlight assembly were once again burnt. I have to purchase 2 new headlight assembly again but the mechanic can not guarantee that this burning situation won't occur. After calling around to places to find headlight assembly I have come to find out many are burnt. This seems like a real problem considering you need headlights to drive at night. Spending 1,000 everytime my headlights burn out seems 100% unreasonable and the fact that there is cleary a wiring issue within the headlight assembly unit itself seems to be a problem. I have been on multiple forums and this is a common issue. Please fix the problem!!!!!!

The contact owns a 2010 Mazda 6. while driving 40 mph, the door ajar warning indicator and the dome light illuminated independently. The contact coasted the vehicle to the side of the road and noticed that all the doors were closed. In addition, while at a stop light, the vehicle stalled and all the warning indicators illuminated. The contact turned off the engine, restarted the vehicle, and was able to drive; however, the failure recurred three times. The vehicle was not taken to a dealer or independent mechanic for diagnostic testing or repairs. The manufacturer was contacted and did not assist. The approximate failure mileage was 120,000.

Low beam intermittently turns off. Sometimes a firm slap on the headlight is a temporary resolution. I initially thought it was the bulb itself, had it replaced but the problem continued. There are lots of youtube videos on this issue. Mazda keeps telling that this is not a safety issue and they refuse to do anything. If they want to do business in the usa, they need to be safe or they need to go back to where they belong. This issue has been happening since 2014 (I bought this car in 2013)

The low beam headlights on my 2010 Mazda 6 keeps going out. I've replaced each light at least twice in the past 4 years. While I was driving last night, both headlights went out. I think Mazda know that this is a problem in this vehicle but instead of fixing the root of the problem, they keep charging me $60 for each headlight bulb.

The low beam headlights on the car take turns going out for some reason. I have had the car for five years, bought it brand new and have had to replace headlight bulbs at least 8 times. I have read several other review about the same issue. This is a safety issue, if we to be driving at night and both headlights go out that would be very dangerous. Second issue: Every winter when it gets colder the cars electronic system seems to run much slower and the blue tooth, cd player, etc. Will not connect and there has bee three instances where the car will make a loud popping noise while it is in motion and the whole stereo system, blue tooth, dashboard lights will power off and I'll have to reset up the blue tooth.

Vehicle was repaired as part of NHTSA campaign number: 11V134000 on 21 July 2011. However, vehicle's fuel tank cracked in April 2013 and had to be replaced at owner's expense. After smelling gasoline after fill up and noticing a puddle of gasoline in driveway in April 2013, owner had vehicle towed to Mazda dealer for repair. Dealer replaced tank on 15 April 2013. Over the last year and several attempts, Mazda has since declined to reimburse owner for repair and reprogram ECU per NHTSA campaign number: 14V114000. Recall from July 2011 was supposed to eliminate the possibly of a cracked fuel tank, but it didn't. owner has pictures of cracked tank and dealer work orders from July 2011 and April 2013 and can provide if needed. Owner worried that if the ECU isn't reprogrammed, the tank will crack again.

My car was parked, went inside store for a minute, came out and it wouldn't start. No lights prior, and I take meticulous care of my car. After a failed jump, tow was issued. The mechanic says it's a starter failure- at 42,000 miles on a brand new factory line car. Now Mazda will not respond to complaints, and attempts at reaching any supervisors have been negated. Car has been immobile for over two weeks. 42,000 is a premature failure for a brand new factory part- and the car company should pay to replace a defective portion of the vehicle.

Both rear tire pressure sensors failed due to either over-tightening or corrosion. Both sensors snapped off right below the sensor stem cap causing both rear tires to deflate. On a newer car still under warranty, Mazda claims sensors are only covered until 36000 miles. And they're not cheap either ($80 each, not including installation.)

I was driving on the freeway after leaving class. After being on the freeway for about 5 minutes, the car starts to power down. All of the caution lights start to come on (ie: Battery light, traction light, oil light and many others). As I get off the freeway, the car starts to lose more power, the fuel acceleration did not work as well and the steering became very hard because something happened to the power steering fluid. Then as I start to pull into a parking lot there is smoke coming from both sides of the closed hood. I put the car in park, turn off the acceleration, and pop the hood and I noticed it is on fire. I ran from car and called the fire department. After all is said and done, the car is totaled. I am not sure what components malfunctioned in the car which insurance is determining at the moment. This is a Mazda defect!!!!!

The contact stated that the start/stop button was located below the air conditioner button and the contact believed the location of the button was a safety hazard. The VIN was not available. The approximate failure mileage was 25,000.
