alterra 05 problem Engine problem

[t3kk3n]

hi guys
we owned an alterra 05 matic 4x2 model. mileage is now at 40K ++. it is casa maintained at isuzu alabang.

Problem : pag start na ang engine, walang redondo, all indicators are OK naman.
ginawa ko is off ulit, then start again, me delay ng 5 seconds bago nag start. so akala ko praning lang... so inulit ko ulit... same problem nanaman.. muntikan pa di nag start kasi mas matagal ang delay nya ngayon 10seconds bago nag start.

na encounter nanamin eto last year.. ang ginawa ng casa eh ni-reset ang ECU kasi daw me error. di naman nila binigay ang exact error. basta nag reset lang sila ng ECU. tapos ok na ulit. now just last weekend na encounter ko nanaman. so assuming i-reset lang ulit nila ang ECU. pero di naman pwede pag ganito ang problem eh palaging ibabalik namin sa kanila ang sasakyan at i-reset ang ECU palagi. madami ng napalitan sa 40k mileage checkup, hanggang fuel filter napalitan na, battery, breaks, aircon. still same issue pa din pag dating sa ECU. ang duda ko lang is the Glow Plugs baka erratic na kaya di gaano napapansin ang problem, at di ko pa nakita kung napalitan na sya sa receipt, father ko kasi madalas gumagamit


baka me naka encounter na sa inyo ng issue na ganito at kung ano ang ginawang solution.

Thanks..

Bro i had the same problem of hard starting kaya lang di ako sure if it is the same problem and solution natin.. na notice ku lang ito pag nabilad na nakapark matagal o ginamit nang matagal sa long driving na sobra init nang makina.Ang ginawa ko nag shift ako from synthetic 5W-40 oil to semi synthetic 15W-40 caltex sports delo and nagpalit ako battery to motolite enduro.So far hindi na naulit,smooth sailing na..Better consult a trusted mechanic in your area before resorting back to your casa.

our isuzu alterra is now at isuzu alabang for the checkup. a new problem was experience last sunday, hard starting (the battery is new-sept 09). then after a few more minutes it started but you can feel loss of power when accelarating... i already talked to an SA as the Service Mgr was making rounds at the shop this morning. I'll call again later today, to get some updates.

Thanks...

You might have been bitten by the crappy Denso Injector bug (same problem as the D-4D).

Alterra was relesed yesterday.

Finding was that the Immobilizer needed a reset.. (Again????) it has been reset for how many times already during its warranty coverage and after warranty still the same process.. immobilizer is always blamed (last year it was twice it was reset)... i already asked them what causes the immobilizer malfunction, they told me 1 reason, dont quick switch on/off the engine if it doesnt start (puro redondo lang). This will break the immobilizer, i made a followup question before we did that, why in the first place the engine wont start? (puro redondo lang) ... .. the answer.. no answer... during the diagnostics they found out that the program in the immobilizer is not working this is why they need to reset the immobilizer... no further explanation... What the !*#$! I've asked them what made them decide to reset the immobilizer? its because there are errors, but what causes the error... not properly explained... hayyyyy....... I need to know what is the root cause of the problem and not an interim solution only.... Im guessing we got a lemon unit with defective immobilizer and was hidden or ignored or overlooked by the casa mechanic when we first encountered the problem.... tsktsktsk.... Its a good thing its casa maintained, i already called isuzu philippines head office to look into this matter. Im just waiting for their feedback..

But anyways, the alterra now is working, thanks to benzmizer and the contact person he provided the service manager, he is very attentive... and take note of the problem.. but im not satisfied to the conclusion... Im no expert mechanic, but the frequency the immobilizer is bugging down, tells me there are other problems they are not looking into or simply ignoring...

No worries my friend. I, myself, ain't satisfied with how your queries were answered. In the meantime, observe the unit. If in any way the malfunction recur, let me know. It'll be a good time to test the damage extent a pack of C4....

Good thing Immobilizer lang pala and not the engine. Hassle lang talaga.

You are right, you need to find out what's causing the immobilizer to err.

But wait,

Hindi ba ECU ang ni-reset nila? Kasi ang injectors controlled ng ECU, and if it errs, di talaga gagana ng matino ang engine unless i-reset/burahin yung error codes. Make sure that Isuzu is not giving you the run-around.

Sa Toyota D-4D problem kasi, ganyan din ang stop-gap measure nila. Pag nagc-choke yung engine, ire-reset yung ECU para gumana for the mean time. Meron mga balik nang balik, meron namang naayos at bumalik after a year or two pa.

Good luck

*benzmizer : Thanks again. Right now alterra is running Ok.

*horsepower : yeah i also read about some of the D4D's issue specially on certain Gasoling brand... i dont want to mention the gas brand as it is not affecting my Strada, its just the alterra that is having problem when it was loaded with it anyways... we are not loading that type of gasoline/diesel brand in the alterra just to eliminate the gas/diesel issue.

*** anyways, ill be monitoring the performance again, and soon will post if there is another problem of the problem re-surface again.... I already called isuzuphils, im just waiting for their feedback on my concern. or otherwise ill be walking at their doorstep (like what i did with near by dealers in the area) their Corporate management was so sorry and immediately lighted some butcheeks on the dealers for my filed complained

correction on my post, I was informed by may dad, the problem was experienced again thursday, although he thought he didnt start the engine properly so he did noticed that the hard starting is back again... Friday, definitely there is a problem as it takes to 2-3 times before the alterra is to start. And just this afternoon is the worst.... it wouldnt start at all after following what the technician mentioned how to start the alterra if hard starting was experience, this procedure was executed but Failed, the alterra doesnt start at all. my father is about to call in the towing service when he just tried to start it for the last time.... and... it did start.. he just went home to be safe and not be bothered by the engine problem... so instead of doing some other walks he just cancelled it and called me later this afternoon to inform me for his frustration on how our alterra was poorly service by isuzualabang.. there is some areas that are being overlooked . For me, this is becoming an Issue now... Im still hoping your Big Guns can do something about it.

Thanks again....

I see. As I have said, relax ka lang.... tried and tested na mga boga ko.... expect communication from "higher ups" soon.

final update on our alterra

Isuzu alabang cannot identify the exact problem. My hunch is that the immobilizer is already busted, and they cannot find a way to identify or test the functionality of the immobilizer when we first encountered our problem during the warranty period. i was told the immobilizer is at around 10k.....

Anyways, we told them to disable the immobilizer(not removed) as it is embedded to the system of alterra according to them

it has been a month, and our alterra is still running and the hardstarting have gone away after the immobilizer has been disabled

Sir, magpapa 15K ako sa ALterra ko, balak ko sana sa Inteco Q Ave pero sa tatlong balik ko dun, di ako satisfied sa service, not sure even kung ano ginagawa nila.

San po ba ok for 15K? Wala pa naman ako reklamo pero yung tunog ng idling di smooth, not sure kung yung belt. 2 years na Alterra ko ngayong December.

Thanks.

Are you from Quezon City? If so, you can try Commonwealth or Pasig. Pasig (from my knowledge) has reputation of having champion mechanics they participate when ISUZU HQ whenever they conduct a competition.
