But this is only a guess. It cannot be replicated as it is so infrequent. Not enough to scream about. It is the nature of all things digital. Gremlins. These are baby ones. Just have the incident logged into your service history.
#11 of 29 trip meter resets for no reason by hyundai2 May 12, 2007 (12:42 pm)
I have one of those, it was standard equip. on my 06 Zer. Picked it up new Apr of 06, and for the 1st 5000 miles it was intermitant, reset itself about 15 20 times. It's been in 2 times for that, plus the dreaded clunk. Dealer couldn't duplicate, what a surprise, so they threw their hands up. Zer went from 5000-17000 miles with no resets, and now it has started up again, 3 time in 400 miles. I keep it on MPG ALL the time, and intermitantly, when I start the car, it will be on Trip meter and showing all oooohs. I have also noticed that if I junp another car from my Zer, (which I will always do withOUT mine running, to avoid damaging the alternator diodes), it will usually reset then, so I feel the problem must be voltage drop related. Have any of u noticed, while driving at night, your headlights diming when taking your foot from the throttle. Mine does that also, which is a voltage drop in the charging system. With a volt meter hooked in, it will momenterilly(sp) drop back to 13.5 volts, which is in specs, but the very bottom edge. I have wondered if that might be related to the trip meter, but then I start to wonder, DO I REALLY WANT AN IDIOT IN THE DASH CREATING EVER MORE PROBLEMS? I am willing to just leave bad enough alone.
#12 of 29 mine does this too by cbrturbo May 15, 2007 (3:51 am)
can't figure out a rhyme or reason to it   definately not because it cracked 999 miles, i reset it every fillup, and many times i cannot use it to verify gas mileage because it zeroes itself out   and i second the thought that i don't want some idiot ripping apart my dash, i'll just live with the problem on this one.

Replying to: cbrturbo (May 15, 2007 3:51 am) Just a thought here...check your negative battery terminal! I say that because when I purchased my car after about a month one morning my car would not start! no power! Opened up the hood and my negative terminal was loose. Tightened it up and no problems since. Just a thought.   Ciao Replies to this message: gamleged (May 15, 2007 5:24 pm) floridabob1 (May 16, 2007 2:21 am)

Replying to: sergio19 (May 15, 2007 2:08 pm) Since the owner's manual states that disconnecting the battery resets the data, that indicates that the data is in a volatile memory, so any power interrupt to the circuit (like a loose/intermittantly loose battery cable or fuse to that circuit) would cause the effect...

Replying to: gamleged (May 15, 2007 5:24 pm) If the power source were to be interupted, would not all of the volitile memory be lost? This would include all features of trip computer, presets on audio system, clock etc.
#16 of 29 TRIP METER RESETS FOR NO REASON by hyundai2 May 16, 2007 (5:25 am)
it has to be an intermitant power problem to the trip meter. If it was further upstream in the power line, it would effect other items. My thought is it has to be a problem in the circuit board, too slim of a chance that their are this many Zers out with the same loose wire, but during manufacturing, one slightly off adjustment on one machine, an you have a bunch off bad boards. One other thought. HOW MANY OF YOU HAVE NOTICED, WHILE DRIVING AT NIGHT, THAT YOUR HEADLIGHTS DIM, NOW AND THEN, WHILE TAKING YOUR FOOT FROM THE THROTTLE PEDAL, ESPECIALLY WHEN EXITING THE HIGHWAY???

#17 of 29 Mine resets too by plannermann May 18, 2007 (3:22 pm)
I have also noticed this little reset thing - I am about to go in for my 15K chek-up, I will have them check the batt to make sure its tight.

Replying to: floyd2222 (May 10, 2007 11:33 am) Yes, my '07 Azera trip miliage has reset by itself at least three times during the 1900 miles and three months it has been driven. Actually, it happened this morning. And NO it is not due to a recycle (1000 miles) and NO the battery was not disconnected, and NO it did not happen at Night. In fact, at first I was about to blame the wife for doing it? I will discuss this with the dealership at the 3,000 mile oil change and check up. In the meantime I will check this site for more info.
#19 of 29 Re: Post #16.. Headlight dims on decelleration?... by gamleged Jun 28, 2007 (7:20 am)
Replying to: hyundai2 (May 16, 2007 5:25 am) On another forum I found, today:   "My wifes 2006 Azera has a continuing issue that I was hoping someone is familiar with. The dealership is pleasant, but clearly thinks we are just exagerating. From road speed when you begin to decelerate..just as it finally drops into low gear, the headlights will blink off ( or at least so dim that you can't really tell the difference) and then once the transmission has slipped completely into low (1) it is over. I have seen it occur when braking at higher speed but it may have been a combination of braking/transmission change to a lower gear. It is aggravating and the guy in front of you thinks your flashing your lights at him. This Azera has 9000 miles on it and has been a joy to own. We have 2 other Elantras that my daughters drive and one has 35,000 and the other 18,000 and zero problems with either one. We are very satisfied 3 Hyundai family...now if we can just get them to bring me a truck over here. Any thoughts on the headlight issue would be appreciated."   I've informed him about your post and the fact that I haven't seen this problem mentioned anywhere else but your mention here...
