Ever since moving to Maine and keeping my car outside during the winter I've had problems with my Mazda3 starting in colder weather. AAA has jumped my car several times and the technicians say my battery is fine (it's about 2 years old at this point).
My Mazda 3 has a cranky start in sub 20F temps, will not start at all in sub 0 temps. The battery is fine. Is this problem endemic is Mazda 3's only? Years back I had a 626 that never had problem with starts in the cold.
This is the first winter it has hit record lows and I have had difficulty starting the car. I just recently ( two weeks ago ) got a new battery because mine had died. I still have a problem at 14 degrees outside starting the car. It cranks a bunch of times before starting.
The engine is very difficult or has a VERY hard start in the cold weather after sitting for a number of hours.
I park my car in a garage overnight. I drove my car 30 miles to work. It sat all day in the parking lot. The temperature never got above freezing. In the evening when I started to go home, the car would not start. The battery is fine. I tried to start it while the headlights were on and the headlights didn't even blink. That seems to tell me the starter is not engaging. We tried pushing it off (standard transmission) but it would not start.
During extremely cold weather, the car would not start. After knocking on the starter, it would finally go. This happened for 2 winters. I was going to replace the starter on the 2nd winter, but I could not get one anywhere. The fix was I moved away from Chicago to Denver. Havent had that problem for 2 winters since
