Has the rear suspension been inspected? I’d ignore the e brake as a culprit unless there are other issues with rear brakes.

Got a 2016 2LT @ about 52K miles. My biggest concern is the CVT, but you don't have that. Only real technical annoyance is the receiver in the car that detects the key fobs is quirky. Otherwise, interior dash parts are fading and steering wheel ("leather" covered?) shows significant wear. Everything else has been great @ 5yrs/52K.... except it has been hit twice in parking lots. Maybe it's too small to see???

Have a 2016 Spark 2LT gas. Since new, sometimes the key fobs are not recognized. Doors won't unlock, push button start won't work. It was only happening about once every 3 months, but now seems to be about once a month. I have carried both fobs together and they both work at the same time or both don't work at the same time so I'm convinced it's not the fobs. When I reported it to the dealer while the car was under b2b warranty, they updated some software. But that didn't fix it. And now they're not wanting to cover it even though it was pre-existing.

Was in the same scenario with a Ford. Dealer wanted $6900 to replace the CVT. The local transmission shop put in a remanufactured unit with a one year parts & labor warranty for about $3800. And good thing they talked me into the one with the warranty because it went bad within a month. The shop dealt with the supplier and got another one and got the labor covered. All has been good a couple years later. CVTs are crap. To me, the Spark is a brilliant car except for the stupid CVT. Just curious, did you ever get the fluid and filter changed in the CVT? Manual says do

Here are my real world stats on this topic using my 2016 gas Spark with CVT.... Towed about an 850 lb pop up camper (it's a tiny pop up--much smaller than even a normal pop up) 200 miles through Kentucky. It did perfectly fine handling/pulling/stopping. The car was loaded with just me, a large cooler, and moderate amount of luggage for one. To tow somewhere that has more sustained hills would be worrisome. I would fear heating up components in the mechanics (especially the CVT). Unfortunately there isn't really any space to beef up with some aftermarket cooling componen
