The rear does more than just roll along the road and contribute to the braking; it actually helps support a fairly heavy vehicle. Most of these type vehicles seem to be getting rather poor tyre mileage and our tyre specialists report similar mileage to that you're getting. Keeping a watchful eye on the tyre pressure to make sure it's up to spec is one of the things you can do, it's also worthwhile checking the alignment to make sure that's in spec as well, particularly if there are any signs of uneven wear across the tread.
It could be local interference. I would consult a local locksmith for starters and have them check the lock. Most locksmiths now have the capability of checking and programming keys and could have the local knowledge to tell you if it is interference. You could also check local radio hams, who might be able to help.
Problems with central locking systems are not unusual, have a locksmith check it. Most locksmiths nowadays have the capability of coding keys for most popular models, and they’re usually much cheaper than the dealers.
Hyundai claims your car should do 9.4 L/100 km in urban driving conditions. That's what they get under standard test conditions, and while that doesn't necessarily translate to the real world it is a guide as to what you could expect. On that basis your car is using too much fuel, but not enough to cause too much alarm at this stage. It is still quite new and the fuel consumption should come down as the engine beds in with more miles. I would take Hyundai's advice and monitor it through to the 15,000 km service and if it is still too high have the dealer run a diagnostic check on it.
It should tow your trailer without a problem, as long as the trailer is braked, and you are sure it weighs less than 1000 kg when loaded with all of your gear. In addition to the cars you are looking at there are plenty of other cars that could also tow your camper, like the Hyundai Santa Fe, Nissan X-Trail, Honda CR-V etc.
The dealer is best placed to find and fix the fault and you should maintain the pressure on them until they can sort it out to your satisfaction. I would simply let them know in no uncertain terms that you believe the car to be dangerous and leave the car with them until it is fixed. They should supply you a replacement car while they have yours.
Straight back to the dealer. If the dealer doesn't know what is causing the problem they can call in the experts from Hyundai. Your car is still under warranty, so Hyundai is responsible for fixing the problem to your satisfaction.
The Sonata has a respectable maximum towing capacity of 1700 kg (braked), but only 750 kg without trailer brakes. On that basis you would need trailer brakes to tow your campervan, a good safety measure in any case.
Driving it more regularly is not the answer; there is a drain on the battery when the car is sitting that is causing it to go flat. The first thing to do is to check that there are lights, like courtesy lights, boot lights, glove box lights etc. that are staying on instead of switching off when they should. Computers can be a source of a drain if they don't go on to stand-by mode when the car is switched off. I would suggest you take it to another auto elec and have them thoroughly check it; they should be able to find the fault.
