First, thanks for all the info gathered from you all regarding the Volvo V70s. Next, my question: I have a 1999 Volvo V70 t5 auto with 69000 miles on it. In the last 5-6 weeks it has developed a stall at start up. Car will turn over and run for 1-2 seconds, then stop. Often 3-5 starting/"grinding" cycles are required to get car started again. Sometimes it start right away, other times not. Sometimes it starts, then stalls a second time, usually on the first attempt to restart car. I have never been stuck, but I did take car to dealer for advisement on problem. Technician said they had several that have done this, and it was either a bad "recognition" chip in the key as part of the anti-theft mechanism not communicating with the antennae ring in the ignition switch/steering column or a bad antennae ring itself. He suggested switching keys, after I told him my wife doesn't seem to have problem, and it might just need a new key/chip. If problem happens on other key then it was the antennae ring itself that was bad. After three days with wife's key, problem started to reoccur again, but it seems to start up on first retry much easier than with my key. Does this make sense to any of you? Could one key be more or less "faulty" in its communication with the antennae ring/anti-theft mechanism? Do you think this would be a covered item under extended warranty/pre-certified car? Dealer did update software (of course) and car does run much better than before (it seemed hesitant/sluggish) but I was unsure as how to proceed. Try new keys first, replace antennae ring, or other suggestions about this problem.... Thanks for taking the time to read and answer, you all a big help...
