I am not sure what is wrong with my Hyundai Santa Fe 2016 because it is at the dealer at this moment waiting for a diagnostic test. I started the vehicle and heard a revving-up noise. I went to the doctor and on my way back to the house I accelerated and heard a rattling sound and the oil light, the check engine light, and the battery light all came on. The car slowed down and when I tried to accelerate again there was no acceleration power. I drove the car as far as I could go, then it stopped in the middle of a road. Thank God I was in my subdivision. I had to ask a UPS truck driver to push it to the curb. It was towed to the dealer 12/26/2023. That was the earliest appointment because it was the Christmas Holiday weekend. this is my only form of transportation. I am so glad I was not on a main street. UNKNOWN because I am waiting for the diagnostic test results. I am requesting a manufacturer's warranty because I am under 100,000 miles. I did file a claim with my insurance but haven't heard from them as yet.

Excessive engine oil consomption and the brake lightbull keep burning frequently.

- Pompano Beach , FL, USA

The engine has been reported as failed. It is available for inspection. The safety of the persons in the vehicle and on the road around us were at risk, specifically with the loss of acceleration and power while driving in traffic and merging. Vehicle became unsafe for use for our family to use so we towed it to be evaluated at odometer reading of 97,181. What happened: Vehicle suddenly started making knocking noise. While driving the vehicle a sudden loss of acceleration and inability to accelerate. Engine started to shut off when it had been in park and then placed into gear. Towed vehicle to be assessed by a mechanic. When assessed at a mechanic, the problem was confirmed and it was also noted that oil had been consumed and noted to be loosing oil internally and has burn on dipstick. No oil spots noted in area where car had been parked or leaking oil on engine. Mechanic assessed that there was engine failure and the engine would need to be replaced. Mechanic also ran diagnostic testing and noted to only have active codes for the tire pressure monitor system of C1212 VSS. Diagnostic health report noted to have no issues. Readiness monitors completed with no issues. Diagnostic health report available. Transported vehicle to dealership, where it was inspected and engine issue was confirmed as well as identical health diagnostic report. It was reported that this model was not part of the recall and warranty extension because it is a V6 engine and not a 4 cylinder so manufacturer would not be replacing engine. Due to being the second owners of this vehicle, we do not meet criteria to utilize the 100k mile warranty. All of this has occurred with out an engine warning light turning on the dash or service code being found when computer was interrogated.

Engine caught fire while driving. Vehicle is a total loss as fire department did not arrive for 20 min. Currently at a Copart yard in Gainesville, ga. Lucky I was on a rural road and my dog and I were able to get out of car. Only injury is cough that has not gone away after 4 weeks. No warning lights, but did smell what seemed like burning brake fluid prior to fire. Both Hyundai and Farmers insurance have inspected the car. Of note is that Hyundai replaced the engine at around 60k miles due to engine oiling issues.

The engine in my vehicle seized, prompting an inspection that unequivocally attributed the failure to a well-documented and acknowledged issue with the engine. This incident occurred while I was navigating on highway, placing my family and fellow road users in a precarious situation. The dealership's assessment reaffirmed that this recurring engine problem afflicts my vehicle model and had been thoroughly scrutinized by their experts. Remarkably, there were no warning signals such as the engine light or oil light to forewarn me of the impending engine failure. Despite having undergone a recent oil change, no apparent symptoms signaled that my engine was running perilously low on oil. Regrettably, Hyundai has chosen to decline any responsibility for replacing my engine or extending assistance. Their reasoning is grounded in my failure to procure a software update that, unbeknownst to me, was an essential requirement. Furthermore, I had received no prior communication via mail, email, or phone alerting me to the necessity of this update. It is crucial to note that this software update, while designed to enhance warning mechanisms, does not offer any guarantees against engine failure but merely serves to provide advanced notice of potential issues.

The vehicle will not accelerate over 30mph. I was entering the interstate on ramp and am not able to accelerate to the speed limit. The cars approaching had to slow down significantly to avoid a rear end collision. This happens every time whether I am at a stop light on a normal roadway or entering the interstate. There are never any warning lights or sensors indicating that there is a problem. I have completed all of the recalls and system updates required by the manufacturer. I have completed the oil consumption and engine cleaning multiple times and it has not helped the issue.

It has been inspected and they agreed it was due to the known faulty engine. -my engine failed in the middle of the highway endangering my family and anyone else on the road. -the dealership confirmed that this is a recurring problem in my vehicle and has been inspected. -the engine light nor the oil light came on to alert me that was engine was out of oil. Yes I did have an up to date oil change. No other symptoms were present to indicate I had no oil left. Hyundai has refused to replace my engine or help me at all as I did not get a software update. I was never aware of this update nor had any correspondence via mail, email, or phone to tell me that I needed to get it.

Seat belt on drivers side does not retract without assistance. I took it to Hyundai and they refused to fix it while the car was under warranty. The engine started burning excessive amounts of oil around 60K miles. We changed the spark plugs and found them to be covered in oil and corroded. We changed them again and they are worse. (Recommended every 100K miles.) The engine stalled once in traffic and continues to nearly stall when driven. The car has been burning in excess of 1 quart every 1000 miles since turning 75K miles. We were never notified of the engine failure issues with our SUV. At 96K mile it became so bad we took it in to Hyundai in Perrysburg OH Taylor Hyundai. We were informed about the engine issue and they began an oil consumption test. However the technicians when instructed to add 2 1/2 quarts of oil they added 5 ruining the testing. Then they claimed that the engine was only consuming 1/2 quart however we took a picture of the dip stick prior to brining it in and the oil was as always below the "L". We were then told we had to pay for an $800 engine flushing followed by 3 more consumption tests. Even if the tests show more than 1 quart of oil burning Hyundai may still refuse to replace the failing engine under warranty.

We recently had the car to the local dealership for engine problems. It took over 3 months, but they finally determined that the camshaft was "bent" and they had to remove the engine to replace it, costing almost $5000. We had it back for about 3 months but didn't drive it much since my wife works remotely from home now. My son was driving it on the interstate and the engine threw a rod, spilling oil onto the exhaust, which caught on fire. He managed to pull over and get out of the car and by then another motorist had called 911. There was a firetruck at the exit he had just passed who showed up in just a few minutes and put the fire out before the fuel system caught on fire, thankfully. While I'm glad my son was uninjured, I'm still very upset by this, especially since they just worked on the engine. After some searching on the internet, I have found that this is a very common occurance for this vehicle (and other Hyundais) yet the company is not doing anything about it. I also read that there is a separate class action lawsuit for this particular engine (in addition to the one for the smaller 4 cylinder engines), but I'm afraid it will be settled too late to help us out.

On August 11, the car suddenly lost power/acceleration & the dashboard lit up with engine, battery, and oil lights. I coasted down the hill to our home without any power. On Monday, it started again without lights, but we called the dealer & were told it would be 4.5 weeks before they could see us & there was nothing they could do without lights on the dash. So we took it to a nearby service center. They performed an oil change & compression check & deemed everything fine. The car drove mostly fine, with an intermittent pause/hiccup at stoplights. August 26, at highway speed, the car shuddered loudly, & the engine light flashed. As I coasted to the shoulder, there was a POP sound. I parked, turned off the car, & inspected the tires. The rear passenger tire had a 3-in gash but didn't deflate. I tried turning on the car again & it just ground & jerked with the flashing engine light. I called AAA & towed it to the dealership, where it's waiting to be inspected. This is a Theta II engine & received the KSDS software recall update in 2019. My child was in the car with me. I wonder if the KSDS gave the first warning on Aug. 11 but failed to stay on to pass on the data to the service center.
