We're have the exact same problem. Car is currently at Electric Specialty shop and they suggest it's one of two issues, Alternator or the VCM (computer). I told them the Alt was new but they said an after market alt might actually cause the problem. We're going to replace with OEM Alt and see what happens. If necessary we'll move on to the Computer.

Bought a used alternator off Ebay. Everything is normal now. Got my money back for the reman, only gave 10 for the core though. I still want to know what the problem is.

I have been fighting this issue for several months. I have a 2006 saturn 3.5 L awd. Here is the ISSUE and I hope this helps all that read it. DO NOT TAKE IT TO A GM DEALER. Will just cost you money and time and all dead ends. IT IS NOT A COMPUTER ISSUE AT ALL. There is a cold start regulator built into an OEM alternator that comes on the original car. It was nothing to do with the alternator at all but you either have to go to a junk yard and get one off a wrecked one, OR have it rebuilt at a rebuild place. YOU CAN NOT USE A REMAN ALTERNATOR FROM GM or AUTO PARTS STORE, simply for the fact it was not expecially built for that engine. I have spent hours, days and weeks of my time on this one issue and this is what I have found. Since these model and year use a HONDA MOTOR , and several years in between there too, I believe the 3.5 L from 05 - 07 the alternator that was used was made especially for that system, it's electrical components and the car. It happens only when it's cold outside or in colder climates, so if you live in Florida ie, you can put a normal reman after market alternator on the car BUT it will only last you a year or so, because it is not meant for that vehicle. So what's ends up happening is that it over works itself because of the voltage regulator and will make the battery wear out alot faster eventually usually causing a short in the battery and making it go bad, also making the reman alternator burn up eventually. SO IN CLOSING YOU HAVE TO FIND AN OEM ALTERNATOR OFF OF A SATURN OR YOU WILL NEVER TRULY FIX THE ISSUE. They are getting harder and harder to find and in my opinion get it checked out at rebuild place before you put it on so you don't have further issues. GOOD LUCK....

I am currently having this issue and I have no clue what alternator will work for my 2006 Saturn Vue 3.5L. The mechanic said that its the right alternator for the car. I am taking video every morning when I start my car to document whats happening but at this point i just need to know what alternator I need to buy to fix the problem. PLEASE HELP! I called GM and they don't even have the oem alternator. I have found several places online that states their alternator is a replacement for gm 12582024 which i believe is the original alternator but I really don't know.

Justin, You have been so right. Today it is not as cold so i went and started my car around the same time in the morning and guess what.... it started just fine, no lights flashing, radio stayed on and power steering was fine so it really only happens when it's cold. I video today aswell and made sure I put the temperature from my mirror in every video. As of right now I just don't know what to do, should I try to find one from a junk yard. The the alternators that I am looking at states that they are compared to the oem. I am suppose to take my car back to the shop on monday for them to keep it a couple days to see if it happens to them but at this point I just want then to take their alternator out and my money back. If you know where I can find the correct alternator please let me know. Thanks again Desiree

You need a specific OEM alternator (a Denso alternator). Any aftermarket alternators or new alternators from the dealership will not work. All the other alternators are causing a voltage spike (up to 19V) after an the car sits in the cold for an extended period of time.

O'Reillly auto parts is where I purchased a new one to replace the used one that failed shortly after it was installed. There is an online used used auto parts store called Chuck and Eddie's that I have purchased an engine from.

I too had this problem. The alternator amperage was too high (135 amps) and the computer in the Vue shut down everything electrical to protect the components. I even had my headlights blow up. I replaced the 135 amp alternator with an 110 amp alternator and that solved the flashing. The computer accepted the lower amperage alternator and did not need to shut down the power to the vehicles components protect them.

Replaced alternator on my 06 Vue twice and it seems to need a new one today. Replaced the battery and it won't charge until 2500 rpms. ?
