Interesting. I haven't heard of issues with the Santa Fe's but I'm not invested in Hyundai forums or social media or anything like that. Only problems I've had with our sonata are:Have 2 acquaintances here with problem Sante Fe’s. Both extreme oil consumption 2017’s - one @ 80k and one @ 100k. The 100k one blew up the motor. The other threw her hands up after trying to get some dealer satisfaction and traded it on a new RAV4. Turns out they’re not the only ones.
1. Rubber isolator in the electric power steering assist (EPAS). The rubber in the motor assembly was too soft and fell apart. Gave an annoying rattle sound in slow speed situations as it was now metal against metal. Replaced under warranty, as they actually added additional warranty to cover the issue. There was a TSB and everything. It's literally an $8 part and can be replaced in driveway but I let them do it.
2. The activation switch for the AC doesn't work correctly. So, sometimes at idle the ac doesn't work very well. Anything above idle it works just fine (variable vane ac, so rpm has it working without the switch actually kicking it on). The switch is inexpensive but the ac has to come off to replace. I haven't had it fixed and we have just lived with it. I'll likely have it fixed and probably replace compressor at same time since it's getting some miles on it. Or I may not. Who knows. LOL
The 2.0 turbo in our 11 was a first year motor and rated at 274hp (3200# car). It's a direct injected motor as well. Interestingly enough, the first generation 2.0 is more desirable due to newer models making less power. Yes, they actually derated the motor. Assuming that is from whatever issues they were having with detonation and such. I've not noticed any detonation, as the car is very quiet. However, I've always run super unleaded, and some people do not.
