I bought my '16 Z certified pre-owned at a local dealer back in September. I have recently been having problems with my car not starting. I am a student at university, so I leave my car parked on campus for the week then drive home on the weekends. Well last Monday (11/11/2019), I accidentally left my dome lights on when I got out. Needless to say, I walked back to a completely dead car on Friday (11/15/2019) afternoon. I had the campus police give me a jump start so I could drive back home. That weekend, I swapped out my wheels with my winter set that do not have properly paired TPMS sensors (not sure if this matters, but I'll list it anyways). I thought everything was fine until I went to drive back to school on Monday (11/18/2019) morning. When I pressed the ignition button, the car seemed like it tried to start but didn't even fully crank over the engine. The engine more or less just clicked once then error messages came up saying, "Check braking system" and "Check ABS System". I then checked the voltage of the 12v battery and it was somewhere around 10v. I had AAA come give the car a jump and drove it right to the dealer. They ran some tests on the 12v battery and everything came back clear. I drove the car back to school on Tuesday (11/19/2019) evening. I went to leave campus tonight (10/20/2019) and the same problem happened again. At first when I pressed the ignition button, the engine clicked once but didn't start. It also gave me the same warning, "Check ABS System". I then held down the ignition button for a few seconds, then it decided to turn over.

Does anybody have a clue what could be going on?? (because I don't:unsure:)

I will update if I can find the problem.

After you ran the battery dead it never got fully charged. You need to get it on a charger and flip dome light switch to door or off. Once battery is fully charged check voltage and ask dealer to load test it again. Buy a LI-ION jump box keep in car so you can self jump. AAA will only allow so many before they charge and besides on busy nights it can be hours. AAA can load test if it is their battery replacement truck. Some tow trucks can too. They usually test before jump starting.

Good luck.

Thanks for the advice. I've been looking at li-ion boost packs, so I think its time to buy one. I have about a 40 minute drive to and from school, so I assumed the battery was fully charged but I'll have to check that.

There is a weird thing that can happen when you run a battery dead. Batteries are made of cells. If you run it dead one or more cells can reverse polarity and even if you charge it properly it does not reverse back so battery never gets back to full voltage/capacity.

Add to that cold weather which affects capacity and it all adds up to issues.

Additionally the CRZ does not charge the 12v battery as aggressively as most other cars. See when the battery was last replaced, and if the dealer will cover that. The VW christmas tree of lights, especially the ABS and VSA lights when stationary are symptomatic of a weak/underperforming battery.

The CRZ has issues with the 12v battery. It is a design flaw in my opinion, but Honda will not acknowledge it or correct it. I have left my radio on while cleaning my car. Maybe 15 min or so, and the battery was dead. It is not very forgiving.

Keeping a booster battery on hand is not a bad idea in this car.

For what it is worth, you do not have to buy an expensive battery. I replaced mine with a Lawn & Garden battery from Advanced Auto. It had the same specs. A little smaller dimensions. Hooked it up...works like a charm. I had a coupon and paid 39 bucks for it.

The 12v in the car basically isn't really sufficient for the job that it needs to do.

If you sit with the lights/stereo on for anything more than a few minutes, leave the car for more than a week or so or you have a 12V that isn't in the best of health then you will get issues starting the car. Any combination of these three will make the problem more obvious.

I refused to replace the battery for a while as I was convinced that it was something else, but you basically just need a good healthy 12V in this car and be diligent with not switching the interior circuits on whilst the engine is off.

Kinda necroing the thread but, just a bit of a cheat.

If your 12v is dead, you can use the hybrid battery to give yourself a jump start. Put the car to ON but turn everything off and wait awhile. Then, try to start the car.

I'm definitely not going to say it's a guarantee, but I can say it saved me one day after work.

Had to just replace our 12v and car was doing the same thing as OP. Hopefully it'll be alright. She regularly would not drive the car for periods and never had an issue until recently so hopefully new battery won't be giving us random issues.

What model year CR-Z and was it the original with eye factory installed battery? Batteries can last many years ( my Moms Buick OEM battery in a Park Avenue lasted 26 years) to a few years or spontaneously fail. They are a wear out item like tires. When they act weird they need to go. My OEM battery failed under warranty after 2 years on a daily driven car and was replaced by another Honda branded battery but with no eye.

If car sits for long periods of time get a trickle charger and use it. Do yourself a big favor and also buy a LI-ION Jump starter and recharge it every quarter and keep in the car. I have the jump starter not the charger I am considering one but my car is driven daily over 26 miles and longer on weekends.

The battery was a Honda OEM battery, dated sometime in 2014 and we've had the car since 15. (it's a 12) It sits sometimes but we don't really have a feasible way to trickle charge it living in an apartment. 5 years out of the battery is exactly what I'd expect.

Somehow the one in my RSX is still chugging along and it's a 2012 model hardly being driven 4k a year. 0_0

I too live in an apartment so I understand. I am renting a stand alone garage from my complex so I have space for storage behind The Speed Bump. Since it has a garage door opener I ran a long extension cord from the second outlet through hooks that were already there ( previous renter? ) across the ceiling to the back corner and use that for my compressor, Shop Vac and Hydroshot battery charger. One at a time when needed. I could get a trickle charger if I needed it but I haven't yet. In another apartment I ran the same extension cord out my window to my car for the shop Vac. Another apartment had outdoor outlets covered on the outside of the building I have used those too :ROFLMAO:.

5 years is average these days for batteries in cars. My current Under hood battery is also a Honda Battery but it was a warranty replacement in 2015. You can tell as it does not have the Hygrometer Eye.

I wonder if your battery kept going dead due to a faulty Hood switch for the alarm and it was going off when you were not around? Been a few postings about that, one recently.

I think it went dead because it was just a 5 year old battery. Average battery if you google typically lasts 2-5 years and we were well on the other end of that. That's about what I expect.
