Recent cold weather starts in the morning (40-50 degrees fahrenheit) have caused my car to have poor or stalled acceleration. It will occasionally not go past 20 or 40 mph while the RPMs rev high. The DTC error code would read P2565 as a pending code. An independent mechanic changed out my transmission fluid and switched out my boost pressure sensor but the problem is still there. Hyundai says that they need to replicate the problem but it does not occur when I take it to them so it's very hard to have this intermittent issue diagnosed by them. This is a very dangerous issue in my opinion if your cars engine revs high without accelerating and can potentially cause serious accidents and injury. I know I'm not the only person experiencing this issue as I've read on online forums of other car owners describing the same issue. Please issue a safety recall before someone is seriously injured or dies as a result of this intermittent issue.

Vehicle has been consuming oil between oil changes. Recently the ABS, Down hill assist, and traction control lights came on. We took it to the dealer and were advised it was a wheel speed sensor in the passenger rear, but they wanted over $600 so we did not repair. Two days later all the lights went off and we had no issues. A month later I drove to Florida, checked and filled the oil with a little over one quart. On my way back the RPM shot up to close to 6K, the engine light started flashing, oil and battery light came on, and the car lost all power qnd started shuttering. There was a strong burning smell when we pulled over, that may it hard to breathe. As of writing this we were told it sounds like the engine has seized, but they are 5 months out on looking into it.

Engine suddenly went into limp mode and jerked steering while on the highway (engine light happened AFTER). We started about 60mph, then vehicle slowed to about 30mph in a few seconds. Almost crashed into a semi-truck trying to get my car under control, then almost caused a pileup collision behind a slow-moving traffic control vehicle. Limped into town. Engine was rattling. Found the engine to be very hot under the hood. Found oil dripping underneath (research says certain Hyundai Santa Fe were recalled for this issue). Oil was low, even though I had it topped off less than a week before. It seems this may be related to large oil use resulting in engine overheat. Mechanic later disclosed to me there was oil buildup underneath and in the engine. Towed into another city to get available mechanic. Found error code P1326. Mechanic took a couple days to determine it was NOT caused by faulty sensor. (attached invoice) Towed to another city where I could have it taken into the lot (there is a long backload of cases at Hyundai). I saw about a dozen of the exact same model as my car in the service lot waiting repair (and many similar models). Told by dealership it would take 2 months to repair and there would be a diagnosis fee. This shouldn't have happened to my car. It was relatively new and low miles for an engine failure. The result was an expensive series of expenses and extremely dangerous series of near-collisions. It has been difficult to contact and navigate Hyundai corporate for help with this. They seem to have a lot of backlogs of these problems related to my model. I get put on hold for long periods. I was assigned case number and case manager who hasn't contacted me yet. I am still without a car as of today.

It appears to be a problem with all the Hyundai Santa Fe Sport. It has abs, downhill, stability control lights on at the same time. It appears to be wheel speed sensor but they do not know which one. The service manager had said it happens to be a lot of the time the rear sensor that goes out. The service manager made it seem like it happens frequently. When I check online a lot of owners appear to be having the same issue. THREE LIGHTS, ESC, DBC, and ABS warning lights turn on. I am in fear for my life, due the safety on the road if the tires would lose control!

Twice engine quit while operating with no warning. Once at 60mph and the other at slow speed while turning around. Restarted by placing in neutral and push start button while still moving. 21000+ miles. Dealer offers no explanation. There are numerous reports of similar incidents with Hyundai vehicles. No fixes I have been able to find and little satisfaction from the mfr.
