2007 Hyundai Tucson - Battery Issue(s)?

Good Morning All,

I have a 2007 Hyundai Tucson (2.0L L4 DOHC 16V), and ever since the winter season began, the vehicle tends to either take a while to start (no clicking sound, however), and when it does start and is running, it would turn off while on the road after some time of driving.

Keep in mind, that for around 2 years now, I haven’t been using my vehicle to commute between home and work, so it’s been mainly sitting in the driveway. My parents would use it to drive to the nearby grocery stores just to make use of it. This is where/when they would tell me the issues happen.

The battery in the vehicle is about maybe 5 years old(?). And my father and I tested the battery and alternator, and the multimeter would read above 14 volts.

What could be the issue here?

Thanks in advance.

It stalls while you are driving? This is a safety issue, and I strongly suggest that you take it to a competent mechanic for diagnosis and repair before that situation results in an accident.

14 v while running is ok, what is the voltage when off? Given how you use the car, the battery is likely bad.

Is there a check engine light on? Alternator light?


After replacing the battery I suggest you get an automatic battery charger/maintainer rated 2-6 amps or so and charge the battery overnight every couple months.


@arvin You never told us whether you solved your Rack and Pinion or steering problems .

You may have a battery that is failing internally and intermittently. How old is it? If more than 4 years old I would replace it if it gave any signs of trouble.

When the engine quits, do all electrical circuits go dead? (No dash lights, headlights, etc?) But then moments later it’s all OK and the engine starts and runs?

But it may be poor/intermittent connections at the battery or an internally corroded wire from the battery. Check those possibilities first.

Along with the above suggestions and questions from other responses to your post.
“ My parents would use it to drive to the nearby grocery stores just to make use of it.” Short drives are rough on the engine by not getting all fluids brought up to full temperature and does not get the battery fully recharged.


Hi @VOLVO-V70,

My apologies. I’ve posted a reply to you regarding your follow-up question to that particular post.
Hope it helps.

Put the reply on the Forum so those who gave advice can see if they helped .

is the gasoline in this car 2 years old?

@eddo I tend to fill my fuel tank as soon as it hits the half-way mark, so it could very well be 2 years olf, if not more (if that is what you’re referring to).
Also, since i haven’t been driving the vehicle as much anymore, I haven’t taken it to get its regular oil change.

@Mustangman mustagman; @shanonia
My father told me that the battery light and oil light would come on.

Hmm, seems it has been two years or more since last oil change. Vehicle subjected to severe service—short drives. Oil level not checked? Battery light indicates problem with battery or alternator, or both.
In as much as you, nor your parents, need the vehicle, fix the problems, then sell it.

If that happens after the engine stalls, but not on with engine running, that’s normal. Those lights are supposed to be on w/key in “on” and engine not running, then turn off once engine is started. A way for owner to tell the warning light bulbs are working.

Ask shop to measure the battery voltage before first startof day, then immediately after starting engine. Should be around 12.6 volt for the first measurement, then 13.5-15.5 volts for the second. Batteries generally poop out at around the 5 year mark, butwill last longer if vehicle not driven much, so your battery could be ok, just discharged and needs an overnight charging w/a battery charger.

old gas could be part of your issues. not sure if it would work, but pull the gas cap and take a wiff of inside the fill tube and see if it still smells like gasoline. if it smells more like paint thinner, it has gone bad.
