Not to fan the fire but in these threads we do see discussions on tow ratings and I have seen posts and videos posted in here, even got in debates on how Tesla's can tow much more than their tow rating. My point with that is it is dangerous to ignore the tow rating limits manufacturers place on vehicles. Not only that, but if proven could void a warranty.

Ok, so back to towing, IF and that is a big if. EVs are used common place for towing in salt water environments, I would have to wonder, over time if this could corrode or decay any protections for the batteries and become a bigger fire danger than it already is.

No one can deny salt and these batteries do not mix, what if the day comes when they are more prevalent at the boat ramps. Its not uncommon on some ramps to back up significantly into the water, so even if the battery pack isnt submerged, would the accumulation of salt over time effect the vehicle. I think its to soon to know, there arent enough EVs on these roads long enough. Meaning years of small amount of road salt hitting the underbody of the vehicles. I have family members, one with multiple EVs that lives on the water on Long Island, his house above flood level but his street gets flooded with salt water with almost every significant storm a couple times a year. Being he is a firefighter, I dont know if he avoids using the EVs on those occurrences but will ask.

Having grown up on Long Island, first thing you would see on a vehicle with a tow hitch, is take a look under the car, even a couple year old car sometimes will show an alarming amount of rust.

This video may fan the fire but I only became aware of it this morning.



Same as above but actual footage from a bystander?, listening closely there was something about trying to get out of the vehicle. With all this said, vehicles running into the water at ramps is very common. But what about the ones that stop just in time and only soak the chassis? Will this take a toll over time. In all fairness I do think, if it became an issue it would be easy to find a solution as we are still in its infancy.

It could void the warranty, but more importantly if you are in a crash it can impact your liability. I had a few claims back when I was an adjuster involving overloaded trailers being pulled by pickup trucks and it never ended well for the person who overloaded their vehicle, to the point where coverage was completely dropped and they were on the hook for all damages.
 
Meh, I’m surprised lists like this haven’t been posted before, I guess nobody ever compares trucks.

Towing with an EV is a terrible idea unless you are just moving something around your lawn or taking a couple of jet ski's to the lake.
You're right, but people do stupid things and with the wrong equipment all the time. I watched a guy many years ago trying to pull a small whaler up a ramp in East Rockway, on low tide. My brother and I were making our way to the channel in his boat IIRC. We both said at the same time this jerk is going to lose his car. He had a VW Rabbit with a stick, lol. Low tide the ramp was like ice, he tried pulling the boat out and the weight of the boat effortlessly dragged his car into the drink, as he first stalled, then panicked and revved the hell out of it spinning the front tires. The area had to be sectioned off to protect the environment, and I would imagine the fine, the cost to drag the Rabbit out, and it probably being a total loss made it a very costly outing.

Think you hit one of the nails on the head.
Since the very first talk of EVs and the almost instantly giddy - run away from the gas pumps - euphoria , several EV owners and builders keep running into the "brick wall." So to speak , with things like ...... extreme cost of maintenance , high insurance premiums to outrageous parts costs causing insurance companies to quickly judge one "TOTALED" to stop or limit their bleeding of pay outs on certain ones along with the surprises of "not enough trained technicians" to "we simply have not crossed that bridge yet , so we don't know!" to cautions about where you can safely travel without "low to no charge..." and on and on.
So, we must all sit back and watch. Well those without so much disposable income that allows the purchase of a very expensive , "extra-almost hobby like" vehicle that families must not depend on , especially in some time of extreme need to move. Escape of large swaths of popuation all of a sudden , to move out / escape the path of storms, floods, snow and ice, fire etc....
Regardless what we think of the whole EV idea at this time those as well as the oooops thoughts on saltwater, etc.... seem to be items that new products just like the very first ICE vehicles had to prove in time. Prove it made more sense to use the ICE vehicles than the choice of real horses over our beloved "horse-powered" rides of today many of us have no desire to give up for "battery power!"
Little by little the bugs will be worked out and the EV will take its rightful (hopefully) consumer-supply-demand place in folks lives. Just wish that it is as time allows , and not as some attempt to force feed all of us by placing the traditional carts before the horses. ***NOT POLITICAL**** Just thoughts about what is happening all over. It is a shame that SOME/NOT ALL of the folks who want and love the EV can not just buy and enjoy them without wanting all of us to HAVE to HAVE them.
 
The recharge/use cycles are pretty much finite and fixed, towing reduces the range so the battery will cycle more.

How would it be any different than wear and tear on engines and transmissions? That's always been the question of utility vs saving any item from its ultimate end by refusing to use it.

Still - battery cycles are weird. Keeping a battery within the center of the range reduces the amount of capacity loss where one can theoretically go through multiple times the energy output with the same amount of capacity loss. Cycling a battery twice from 75%-25% is easier on a battery than a single time from 100%-0%. So there can be things done to reduce battery wear.

Engines and transmission don't cost 60k to replace, in a passenger car at least. and a Tesla semi's battery will be a lot more than that

On days we weren't on our boat. I used to go to the huge Wantagh park boat ramp with my girlfriend on a busy day for entertainment as people launched and pulled boats out of the water. Saw dunked vehicles every once in a while too.

The reason why the "Y" is so cheap is the source is incorrect ;)

There was some claim that the price was going down eventually. I was thinking maybe $10,000 from Tesla. But they still have the 8 year 150,000 mile battery warranty where the only thing that matters is that it's used and charged within specifications.

EVs will need the batteries replaced in 100k miles more than likely. It's noting for ICE engines to last two or three times that. It's always the body that rust away for me.
