Hello and thank you for your post. I am a master certified GM tech, with 15 years Saturn experience,and can help you to resolve your issue.
let me see if I can answer all of these questions...
the warranty should be effective since you continued to have the car service at the same location after Saturn went bankrupt.
will the work be covered by your warranty? in my opinion it should be but that is really the decision of GM
usually if the chain skips a tooth, they will cover it.
although it is a design flaw, they did not issue a recall on this for the ION's, only the early L-series
they redesigned the chain tensioner and were satisfied that they have addressed the issue
I know from experience that the new tensioner did not fix the problem and it is still quite common to cause this type of an issue
will they acknowledge this as teh truth? probably not.
I would approach them with nothing but sweetness at this point in the hopes that they help you. If you come on too expectant they may get miffed and decide to not help you
to determine if the chain is off a tooth they need to remove the timing cover and valve cover and eyeball the chain to see if it is off a lot but if it is only off 1 tooth they may need to remove the chain and reinstall it
this is the only way to know for sure if the chain is off a tooth
as for recorde being stored in the cars computer...not much usable info is stored there with regards XXXXX XXXXX history of the history of the current failure.
sometimes it will display the mileage that the currect trouble code set, that's about it and not all the time
sometimes that will not display either
you SHOULD be able to produce receipts that show your maintenance history from any mechanic that worked on it
if you changed your oil regularly then you should not be liable for the chain if it started acting up just days after the warranty ran out.
again this is my opinion
the diagnosis done by an outside shop will probably run you between $00 and $500 depending on how far they have to go to diagnose this
if the same shop makes the repair, they should roll that $$ into the repair so you don't have to pay the same $$ twice, but only if you make the repairs at the time that the problem isa diagnosed
if they diag it and you leave, you will pay for the diag and then pay for the repair when you come back. This is standard.
they are doing twice the work at that point
to repair the head is about a $2000 job if they have the head reconditioned at a machine shop and reinstall it
including new valves if damaged
I hope this answers your questions
will gm still give you financial assistance if you have someone else look at it?
my advice...have GM do the diag first and takwe whatever assistance they offer rather than get another tech involved.
because then you have to pay the other tech, GM will probably not reimburse them AND if GM fixes it, you will get a warranty on their work for 12 months or 12K miles.
so if what they do doesnt fix it, it will be under warranty
the smell and the rough idle all seem related to a burned valve
I think GM is through issuing recalls on Saturns. No more saturn Corp...so no more recalls.
Thank you for your helpful answers! I hope the GM people will think like you think! Ha! I agree with you that I should take my Saturn to the GM Dealership and hope & pray for the best. I or my husband will get them called today. I will try to give you a shorter update when I know something. Again, thank you for sharing your knowledge with us!
after fixing the burned valve the MPG should improve but I am using the EPA stated MPG for both cars and as you got close to the posted MPG on the S series, I think you should get the posted MPG on the ion.
it is a bigger engine, 2.2L vs 1.9L so the MPG will not be the same
