Well, it’s been a week in the shop and nothing had improved. The word from Polaris is keep looking. No parts have been replaced as of today and the consensus of the dealer is ECM and throttle body both need to be replaced. Polaris won’t approve it and send the parts.
You already have a case number with Polaris- your dealer instigated that the moment they called Polaris with the issue, requesting assistance on diagnosis. If you want to call Polaris, the first thing you need to do is get the case number from your dealer. That way, you can get past the receptionist at Polaris, speak with a "specialist". (I promise, I am using that word in quotations for a reason.......) After you get off the phone with the "specialist" he/she will call your dealer and most likely be extremely ugly-yelling about what an irate nasty customer call he received, and why the hell the dealer had not corrected the problem....... (I speak from past experience.) In my humble opinion, the most prudent way to approach the situation is to be honest with the dealer. After you get the case number- explain to them that you are going to call Polaris, to see if you can help expedite a solution. Make sure the dealer understands that this is no reflection on them. In my particular case-in the beginning, the first "specialist" I had was extremely rude and ugly, both to the dealership owner and the service manager. Luckily, they knew I was calling Polaris, and had every intention of being polite. Another tidbit- I went through several incompetent "specialists", until I found the one willing to be cooperative.
I know that you do not want to hear this, but one week is truly nothing- in all honesty, it will be, at minimum, 30 days before you can start demanding Polaris take immediate action on this issue.
