What 352 owners told NHTSA about the 2012 Hyundai Santa Fe Hev

When my daughter returned home from college this summer I took her Santa Fe to a local shop for an oil change and other preventive maintenance. During the vehicle safety inspection, the mechanic noted the subframe and front suspension components were failing due to excessive corrosion and the Santa Fe was not safe to drive. My question is about the effectiveness of Campaign 947 - Underbody Corrosion Prevention Service. The countermeasure to the Hyundai subframe rusting issue appears to have not been an effective action to prevent the subframe's failure. The Corrosion Preventive Service was completed on our Santa Fe on Feb 13, 2018. Given the amount of corrosion on our Santa Fe, the Service Campaign was not effective, and the subframe failed due to corrosion. Both the independent shop and the Hyundai dealer indicated that the failed subframe would eventually lead to a catastrophic failure and possible loss of control of the vehicle. Given my daughter drives the Santa Fe from home to school on I70 I am glad the failure was identified early so the car could be repaired and prevent an accident.

In June 2021 vehicle experienced engine failure at approximately 152,000 miles. Vin# not under Hyundai Engine recall however Hyundai covered new engine replacement under warranty extension due to failure. In November 2022 received notice for mandatory Knock Engine Sensor Detection Campaign, vehicle had approximately 163,000 miles. Was told this must be performed to prevent catostrophic engine failure. Once campaign was installed in December 202 vehicle immediately went into Drive Safe mode and Engine light came on. Returned to dealership 2 more times and each time vehicle went into Drive Safe mode with engine light. Diagnosis was the new engine was defective and needed to be replaced. New engine has under 12,000 miles. Vehichle is now unsafe to drive as it's in Drive Safe mode and needs engine replacement. Hyundai only agreed to cover 85% of the new engine cost as a goodwill. This is not satisfactory to the customer as a brand new engine, under 12,000 miles and 14 months failed and I do not feel I should be responsible for 15% of the cost to replace a defective engine. The fact that the engine light came on and vehicle went into Drive Safe mode immediately following the KSDS campaign installation means there was an existing defect in the engine that was only detected once the campaign was installed.

I bought the car used and initially didn't have any issues with it. About a year into having the vehicle I saw that the battery light came on momentarily and then went off. Not noticing anything different with car I thought it was no issue initially. Got the car checked battery checked out after I noticed it happen a few more times but the battery passed testing. Eventually the right headlight stopped working. Thinking it was just an issue with the light I attempted to replace it but the light never came back on. Then the left turn signal stopped working. Got the car checked out and was told that the issue was more than likely an issue with the wiring, either a short or potentially burned wire. Took the car to my local dealer and was told the the headlight assembly was the issue and that it would about 1400 to 1500 dollars to replace. Told the dealer what I was told about the wiring issue and was told that I would have to pay for that and the headlight assembly if replacing the headlight assembly didn't fix the issue Managed to get the headlight assembly replaced on my own and the issue still persists. After initially changing the assembly the headlights worked, but on of the running lights wasn't as bright as it should have been. Here recently the right headlight is out again, along with the left taillight and left turn signal.

Engine stalled, shutting down both power steering and power brakes, restarted, stalled again and then never started again, while driving 70 mph on a major extremely busy thoroughfare (SR202 in Jacksonville, Fla.) in 05/13. Had vehicle towed to regular mechanic 05/16 who said engine blown, but under recall. Then towed to Jenkins Hyundai 05/19. They inspected vehicle, confirmed engine replacement based on TSB 21-01-022H testing (they gave me a copy) for recall 198. Jenkins then contacted me, replacement was denied approval by [XXX] PA#[XXX], because it listed as "scrap", that 198 is only a "recall campaign, not a safety issue", engine would cost $12,000,00. I found the 198 SAFETY notice online and took it to them, they said they couldn't do anything, I would need to contact Hyundai corp. Contacted Hyundai 06/01, assigned case number [XXX]. [XXX] from HMAusa (833-462-8722 x [XXX]) emailed asking for info, I returned email same day (06/01). [XXX] then emailed 06/07 and I responded both via phone and email same day. Jenkins Hyundai has since called asking what I intended to do. I called [XXX] and she confirmed vehicle listed as "scrap", but that Hyundai does safety recalls on rebuilt title vehicles to talk to dealer again. I uploaded to HMAusa photos of my insurance, registration, tags and even photos of my car at [XXX], copied also to [XXX] (the prior approval email for dealers) on 06/15. Told [XXX] "[XXX] confirmed safety work on rebuilt title vehicles", but they are waiting on HMA approval. It has now been 4 months and nothing. I emailed Center for Auto Safety 08/18 and they confirmed repair is required by federal law even on salvage title. I emailed [XXX] 08/19 about noncompliance and again on 08/24, uploaded to HMAusa. New HMA #20221366, received 08/30 [XXX] "response in 48 hours". NHTSA #[XXX], spoke with [XXX]. As of 09/07 still nothing.

Got a recall notice about an engine component had it checked they said it was fine. 7 months later it lost power and throw the piston through the bottom of the engine, oil and gas poured all over the road and we had just changed the oil. Called Hyundai and talked to them. They said it would be covered for a new engine cause they had lost a class action lawsuit. It wasn’t the matter if it went out but when it would go out. I towed it to Hyundai where it sat for 4 months before inspection. Then I was told it had to many miles on it so there for it wasn’t covered. But they was quick to offer to order me a new engine at my expense. My issue is a bad part is a bad part. Mileage doesn’t matter. They figured out what mileage most of them was going out at and set a lower mileage so they wouldn’t be responsible. I’ve only had the vehicle 4 yrs and I’m disabled.
