New GEN V has zero physical pieces to change to meet Canadian specs. It is all electronic program changes now to comply with metric, day time running lights, etc.. I believe SRT deliberately did this and is why an electronic gauge pack is so advantageous to the car as it could eventually be sold worldwide as that is the audience it now seeks and will need for ultimate production numbers. There is just one part for all with different programming. Same for languages, etc.
Can't register a car off a PO Box as every state and every province requires a physical location to register a vehicle.
When I (very briefly) considered moving back to Canada a few years ago, I checked with Chrysler and on my 06' Viper which I had from new, I was able to transfer warranty up to Canada in a permanent move of a primary residence only (one time). If I bought it new, was the original owner, lived permanently in the US at the time at a primary residence at MSO and was transferring to Canada permanently, it was possible for transfer in that situaiton only. The only requirement is the car had to be at least 1 year old from date of sale and required pre-approval discussion with Chrysler as well as forms to fill out prior. This was the ONLY instance of warranty transfer. Could not buy from out of country to Canada, nor move with a used Viper with remaining factory warranty, etc. it was not possible for warranty in those situations.
Strange but every company has it's issues. The minute you come through a border to import a car into country, it is logged in the Department of Homeland Security's computer and that information IS directly shared with Chrysler after import. They know right when it is imported in and no warranty is flagged on Chrysler's part. Thus is you bring a US car into Canada, you need to import it in to register it in Canada anyway, thus you are outted at that point and warranty is void, except in the original owner move situation which you also have to notify Chrylser first for pre-approval on that.
Vacationing is a totally different situation as you are visiting either country as a vistor only. Car will be repaired underwarranty in either country irregardless of whether it is a Canadian car or US car, again only the original owner situation with warranty still valid. Outside of warranties, I will state that I have never known of a Canadian citzen/businessor US citizen/business to not stop and help someone in need thus the stranded situation is a moot point.
Chrysler and the government know exactly where the car is registered and the country it is in. There is no way around the system to register it in a weird way to make it work for a warranty situation except picking up and moving with your original purchased car as described. Sorry but the issue is not a US Chrysler issue. The warranty issue is a Candian Chrysler issue and the Canadian Car Czar protectionsim of the Canadian car mafia in charge over many years. Always has been an issue, even when I lived there years ago. I still can't believe there has not been a civil uproar of it as Canadian's have been getting screwed for years on these issues, ultimate by their own. Europeon imports are worst for that in Canada!
In the end, it is crazy but the reality is take 20% off the price of the car and sell with no warranty. If I added up the cost of the warranty for the car including the extended 7 yr warranty I bought, it was all a waste of money. Pay to fix here or there and call it a day. I wish there was an option from Chrysler with no warranty with reduced price. I bet the number of takers would be pretty high. Or make it a 1 yr, 12,000 mile warranty for way less.
Ford makes it work but then again Ford was not owned by governemental bodies in either country either.
