2011 Mazda CX-7Electrical systemLights

The low beam wiring gets hot and melts the connectors to the bulb connection. The low beam headlights have been replaced 8 times in a year due to low visibility. It's like turning off the headlights but they are still on. It's been going on for years. I've taken it to Mazda and the mechanic told me they had a vehicle there now with the same problem and have not figured out the problem yet. Wiring harness has been replaced to the low beam, the connectors and bulbs replaced fuzes and nothing seems to fix it, the...

battery keeps needing to be replaced as well, alternator has been replaced. This is a safety issue due to the fact that the low beams are so dim the driver can't see to drive without using high beam headlights to drive and they are just like having regular low beams on.. I've used halogen as well as led trying to fix it nothing has worked

Low beam headlamps are extremely dim. Have bought new replacement headlamps and are still very dim. Bought both replacement headlamp housings thinking wiring could be compromised but that didn't help either. Replacing headlamps is difficult due to having to remove either the front tires OR the front entire bumper assembly to switch out lamps. No fog lights are present on this model so makes driving at night very difficult. and unsafe.

The vehicle would not start, would stall out and turn off while driving. The driver's side window will not move up or down. The car would start with jumper cables, idle for a few minutes, then go completely dead, no lights, no buzz, no nothing as soon as it was put into reverse. The car has a new battery, new coils, new spark plugs and continues to misfire. Mazda has been unresponsive to messages due to open recalls.

Car had been sitting in the driveway for 2 full days with no use. I walked outside to place trash in trash bin and noticed smoke coming from the drivers door. I quickly ran inside, grabbed fire extinguisher and put out the fire.It looks like the fire originated at the window motor or the window switch panel on the drivers side door.

Opened the driver side door to get into vehicle this morning all was fine. When I got to work and tried to open the driver door, it would not open. I got out of the car by climbing over the center console and opening the side door. I checked the other doors (and trunk) and they all opened. I checked the driver side door from outside the vehicle then and it still would not open. It's a safety hazard if you need to get out of the car quickly. Also I am a senior citizen so it's no longer easy to climb over the seats to open the passenger door instead.

The dim lights are so dangerous and do not provide any visibility at night at all. It is very dangerous to drive and I have had so many near misses while passing other vehicles or trying to not run off the road due to not being able to see. Plus the bulbs burn out several times throughout the year and I'm constantly having to replace them. But to drive at night is so scary because I cannot see the roadway due to poor lighting from the cars headlights. And also the motors that roll down the windows are constantly going out and I have to replace those as well otherwise my window gets stuck and I can't get it to roll back up.

Window motors; shortly after I purchase my vehicle my driver window would be difficult to go up once it went down. Then it got worse and made a loud sound when it went up and one would have to pull it up. Now the driver window does that. Its hard to get it up once its down and makes a loud sound. I find it strange that both windows are now not working.

Takata recall and horn and passenger door lock. I took my car in for the suspension recall and air bags to galpin in van nuys ca. I got the car back and the suspension was done but not the passenger air bag. The reason from the mazda service mgr was since my passenger door is broken ( the lock) he could not open the door so he did not work on the air bag. I can not afford the 200.00 That it will take to fix and replace my passenger door lock. I feel that I should have my door fixed by mazda and then do the repair...

work on the recalled air bag. The door lock just broke on its own and I paid cash for my car brand bmw from galpin. Also I was driving on the freeway and all of a sudden my mazda emblem in the center of the steering wheel blew off and landed in ny lap!! I was not using the horn. I now have no horn and have looked at the fuse and everything else and no one seems to know what happen here. You can see that my mazda emblem is broken all the way around this piece?? Someone said that since there is an air bag in the steering wheel I need to buy a new steering wheel? Really? I am a senior on my social security retirement ..I am not able to have these problems fixed at hundreds an hundeds of dollars. However if my air bag has a recall and they didn't fix it since my door lock is broken and they couldn't open the door. What would you suggest I do? Please contact me with any info you have at [[redacted]] or email at: [ [redacted]] thank you [[redacted]] information redacted pursuant to the freedom of information act (foia), 5 u.S.C. 552(B)(6).?*Jb
