The post 2020 Spyders, and especially those post COVID units, are known to suffer from dodgy battery issues causing pretty much what you've described. It seems that BRP either ran into supply issues or cheaped out on the batteries and installed an inferior product with only a 6-month warranty, and MANY Owners here have reported similar failures and problems that end up being failed batteries! :cus:
So I'd strongly suggest that
BEFORE you do anything else, you load test and check your battery - it's a simple test, and it might just save you a lot of trouble if you do it FIRST, regardless of whatever else you might think it could be, as many Spyder Owners have discovered that these things are
VERY power hungry in a way no other motorcycle we've collectively experienced is! And beware, if it load-tests at anything under 12 volts at any stage, but especially during starting, then the battery is basically toast!! If you don't have access to a battery load tester/can't readily get the battery out and take it to a battery shop (ie, NOT a BRP dealer!) then even just watching the voltage levels on a multi-meter, checking for better than 12 volts after the Spyder's sat overnight/before doing anything; with the ignition on but before starting; actually during the cranking phase of starting; and after the engine has started running can be very enlightening! (If you do the latter multi-meter testing, post those 4 values/readings up here.

) Seeing anything less than 12 volts at any of those 4 stages means that your Spyder's computers will not have enough green steam/voltage to do everything they need to do, and you'll get Limp Mode, VSS Faults, Transmission Faults, &/or possibly even a complete failure of the dash to work at all!!
So with VSS & other faults codes, ALWAYS CHECK &/or REPLACE YOUR BATTERY as necessary FIRST! And if you do get a new battery, then make sure you get one with at least 350 CCA & 21 A/hr output - more is better, less won't work for long if at all, and the post '20 OEM Batteries are substantially less!! :lecturef_smilie:
If you do get a new battery, you also need to make sure that it is
prepared properly and charged properly BEFORE installation - even if the retailer says they did all that and it's OK to install immediately; cos if the battery hasn't taken more than 12 hours to prepare before you picked it up, then there's a good chance it'll just have a light surface charge; and if that's the case and it's installed and used immediately, it will likely fail sooner rather than lasting the years that it should!! New batteries, especially AGM batteries like those most commonly used in motorcycles and our Spyders, need time for the 'acid' to fully permeate the battery after being added to the 'glass mats', and then they need
at least 8 hours of proper 2-amp charging!! Failure to do this will see you needing a new battery again much sooner than expected!!
That said, I do hope you didn't actually leave your Spyder "...in a garage on a
charger..." for a month, cos that
WILL kill a battery!! Batteries don't like being over-charged, and many 'not-smart' chargers &/or battery tenders just don't know when to stop, so you shouldn't leave your battery connected to one of them for more than 12 hours at a time, or you'll likely over-charge &/or otherwise kill your battery! :banghead:
That's not quite the case with 'Smart-chargers/battery maintainers', which are smart enough to shut down once full charge has been reached, and in the case of maintainers, may even start off a maintenance/de-sulphation cycle that actively monitors the battery voltage, regularly applying a load &/or de-sulphation cycle, and charging only when necessary. But even with those, while it won't kill the battery as surely as a 'switch on/never switch off charger/tender', it's still not
best for the battery to leave them connected for months on end, as that will shorten the battery's overall life potential - but at least they'll usually start & run OK after a few months of storage! :thumbup:
So all up, I wouldn't be racing to get your Spyder to a dealer ASAP -
check your battery FIRST, and if it's dead & you've owned your Spyder for more than 6 months, you really don't want another dodgy 'less capable/reliable' off their shelf BRP replacement battery anyway, do you?!
