If you are keeping count, this is number seven for battery failure on this vehicle. Lander's Ford had the car from December 24, 2018 till January 3, 2019 and, again, said they were unable to find a problem and so we were told to pick up the car. On January 31st, the battery was dead again. The car was towed to the dealership on February 4, 2019. They kept the car for almost one month and STILL claimed they could not find a problem. Although Lander's did not charge me, I did have to pay $111.00 to get it towed there.

This battery failure has happened 12-14 times. I have owned the car since 2016. This problem started about 2018. At first I called AAA.But incidents have become so frequent, I now carry a small jump (Noco) in my glove compartment to recharge the battery ANY TIME it is cold outside. Especially if I have not driven in a couple of days and any snow has fallen.

I replaced the battery last year in winter (I will have to find paperwork for specific date). I drive very little and the car has not reached 100,000 miles.

I want to know what is wrong so I can fix it! I just want to know what the problem is. I live in a small town and none of my mechanics can figure it out with certainty. The dealer/mechanics in Santa Fe act like they don't know.

I really like the car (as many C-max owners will tell you... But this is VERY, hugely inconvenient... and potentially death defying if my battery should go out in a precarious situation. As it is, standing out in the freezing cold to recharge my battery is really awful. Thanks for your ear.

I owned the car for about 21 months, and the second battery is being replaced within 14 thousand miles. I have a total of 44 thousand miles on it. It cost me 230 bucks to replace the battery at dealership first time... I've got 2 more years of warranty left on battery. Not really impressed, because Ford does not have an answer as to why this is happening.

I'm not looking forward to replacing the battery every year, especially here in Canada - it's cold in winter. Car was not driven in 5 days but I still should not have a dead battery to wake up too. Other than this issue (and now I see many people have same problems), the car has been good but... I hope Ford comes up with a fix soon with a fix. I am a die hard Ford buyer and fan for over 50 years but... there's many different brands out there, I'm just sayin.

FORD, GET YOUR S*** TOGETHER, PLEASE...

Radio starts to go funky, can not control it, shut it off, change channel. About two days later the battery is dead, and that car will not start. Had it towed to the dealer, 3 days later, they suggest it is the ACM. $870.00 to "fix" it. I know the forum says if it has happened before to list it. However this is the third time it has happened, with this time being the time they seem to have an answer. Maybe it was stupid of me to sink 6K into a new transmission in April of 2020. But now the dealer wants $870.0 to fix the radio drain, that they can't guarantee it being fixed. I guess I was hoping the 43 MPG was going to last, but the thing is they NEVER fixed it the other times.

I went through 5 batteries on my CMax and repeatedly took it in (or, twice, had it towed) to the Ford dealer for a replacement. The battery dying was always preceded (a day or two earlier) by the radio dying. Well, after they repeatedly scratched their heads, I suggested they replace the radio. Well, guess what? The radio was the culprit. I have gone an entire year now without battery issues. Apparently the radio was not turning off when the car was turned off and was continually putting a vampire drain on the battery. This occurred even when I manually turned off the radio before turning off the engine.

OK this is the eighth time the battery has died. It has been at the dealership since June 26, 2019 and is still there as of this writing. I tried to take it to my own (non-dealership) auto mechanic and he apologized but told me he "wouldn't touch that car." He said the battery issue is a known problem and makes the car a lemon. He suggested I contact Ford customer car (which we have already done in the past) and complain and that I should take it back to the dealership and try, again, to get them to fix the problem.

I should mention that one of the service advisors we dealt with was very rude to myself and my husband and kept suggesting that we must be the cause of the problem. We now have a very nice SA, but that's not helping to get the car fixed. Just more run-around.

In retrospect I suppose buying a new model is a mistake. So, aside from about a thousand recalls and getting to know my Ford service adviser WAY TOO WELL, the car has been great when it runs. And therein lies the problem. I miraculously made it 28K miles (2-1/2 years) on the first battery. No complaints there. Since then, I've woken up to a dead battery 3 times. Battery number 2 lasted almost 14K miles just shy of 2 years. Battery number 3 lasted 2600 miles (3 months), and battery number 4 lasted 6000 miles (8 months). Each failure is preceded by several days of no radio.

This last time I even took it right to the Ford dealer and asked them to check my battery. They said it was "fine". The next morning the car was dead. I'm tired of the inconvenience of having my car towed in and the nervous feeling of having an unreliable car. But the worst part is they just put in a new battery and send you on your way. I asked them to check for some sort of electrical drain and they said everything is great. Clearly not. I doubt they even check it.

Now I will never be able to sell this car outright and be honest about its history, so am just stuck with the paltry trade-in value. Will NEVER spend another dollar with Ford. And people wonder why we buy Hondas and Toyotas?

3 days ago, the SYNC with MyFord Touch system went dead - screen worked, but no functionality (couldn't turn on the radio, sensor wipers no longer worked, no backup signal when getting too close to an object). Then, next morning when I was going to take it to the dealer to get that repaired, the batter was dead. Was told the engine battery had a defective cell, so they replaced it.

Worked fine until 3 days ago (2/2/18) when SYNC with MyFord Touch system did the same exact thing (the screen would light up, but no functionality). Woke up this morning to drive it to the dealer for repair, and the car was dead again (no response - couldn't start, screen didn't light up, etc.). When I talked to a Ford rep on Friday, 2/2/18, was told to tell the dealer it needed Field Service Action Number 12M02. Dealer informed me this was due to the SYNC with MyFord Touch System freezing up. Ford rep also informed me on 2/2/18 that my software was version 3.6, current version is 3.10, so it needs to be updated (has to be done by dealer, cant be performed by car owner). When I asked the dealer about this, they said Ford instructs them not to proactively update software unless there is a problem.

There is a DEFINITE problem here! The inconvenience of going back and forth to the dealer and things not being fixed properly the first time around is more than annoying! Will report on this newest failure (2/2/18-2/4/18) in a separate complaint, once "resolved" (if a resolution is even possible, based on all the complaints I've seen in here.

I have had this car for about 3 years, it has been a pain since day one. I had the car just go dead too many times to count. When they jump started it, it just kept speeding up- you have no control over the speed at all, had to stop, shut it off then restart. Finally got a hold of a district manager who assured me the problem was fixed by replacing the battery,,,WRONG!!! Now when I try to start it, it takes at least 3 tries, lights flash on dash and flicker like there is a short. Took it to have it put it on a computer to test it at 2 different places, it throws no codes. I am literally afraid of the car at this point. Ford should figure out what is causing all the issues with the batteries on this car or do a total recall. (oh did i mention the warning light that comes on that says pull over safely...yeah this is "a issue as well" it will not speed up no matter what you do. So you pull over and shut it off, restart and it seems ok well for the next 30 minutes or so. I doubt if I ever buy a FORD again after all the bs i have with car and no one at any dealer can fix or even seems interested enough to research....

Update from Sep 20, 2017: if you are having problems PLEASE CALL FORD AT 1800-392-3673, they send reports to natsa and this is what gets recalls !!!!!!!!

We left the car in bright sunlight and closed the (manual) hatch with the lock already engaged with the keyfob. After about 18 hours, we tried to start the car. It would not start at all. I checked the 12 V battery and it was at 3.5 volts. I put the battery on a trickle charger and was able to recover operation. (This had happened twice before earlier in the life of the car under warranty. The Ford techs could not find a cause either time. They replaced the battery once. The time I describe is the third time for us.)

I tried an experiment and locked the car with the hatch open. Then I carefully closed only the first latch. The lights stayed on for the 10 minutes that I watched the car and never went out. After 10 minutes the battery voltage was 11.6 V, so I closed the hatch and ran the engine to recharge the battery. I am pretty sure that if I had left the car that way, it would have been at 3.5 volts again.

Since some very questionable software has left this as a possibility, the only thing you can do is to carefully check the lights in front or back in bright sunlight to make sure they are out after closing the hatch.

Vehicle started to not turn on, entire car was dead - no locks, could not open the hatch, nothing. It would do this intermittently but then start. About a week later would not start at all and I had to have the battery jumped by AAA, who said the battery was too new to have this problem- had to drive around an extra hour to recharge the battery. Worked ok for about 4 days. Had it checked at Firestone as all the Ford dealers in town were closed for inventory - go figure. They could not find a problem. Next day it did the same thing. Was working one minute - next, totally not on.

Tried to talk on line w someone from Ford tonight, but she just said go to the dealer.

Now I see that this is a big issue with this vehicle - really disappointing

After we had to have the car jump-started last month when its battery went dead, I didn't think anything more about it. Until this afternoon when I went outside and hopped in to run some errands. Car wouldn't start, battery completely dead. This after I had driven it several miles yesterday, being very careful to try and keep its gas mileage up as close to 40 mpg as possible by doing a lot of coasting, careful acceleration, etc. Waited for an hour and a half for Roadside Assistance, and he came and jumped the car and it started. Then we had to drive it for half an hour to make sure the battery is recharged.

At this point, I go online and discover that this is a problem that hundreds of people have with the Ford C-Max. Ford knows about it, and hasn't found a solution. Why does Volkswagen get all the bad press when Ford overstated the mileage on this piece of s**t by about 10 mpg, and allows this problem to go unsolved for years?

I brought this car Dec 29, 2012. It is a 2013 I have had nothing but problems over the last 20 months. Dead battery first one replaced, brand new transmission to which they kept my car for almost two months to fix, I continue to have dead battery issues, many recalls, trunk not working and now the power is draining every where. It kicks straight to gas mode instead of electric, blue tooth not working, dash light was bright even though light switch was off. I completely done with this car. I have written to the Ford corporation and there rep was Ms. Allison was rude and only wanted to focus on the amount of miles that I have place on the car. Again, I have had it!
