We have had an issue with the engine and the oil pressure warning light. Our car seems to also be leaking gas and our repair people have asked us to come in every 1500 miles because there seems to be an issue they do not know how to remedy. We are worried that this is going to get worse and could act up on the highway and result in injury or death. My wife is a 2nd grade teacher and drive this car on the highway everyday.

to whom it may concern , I have a 2017 Hyundai Tucson that has really bad and scary engine and transmission issues , this car has had a recall to fix constant bucking of the engine at slow speeds and even after the recall it went right back to the same behavior and has now developed slow acceleration and has even attempted to stall on the highway during lane changes , it is the only car I have and I have had really difficult times with it and the dealership has once again told me that they have no loaners available and that they likely will need a few days to diagnose the issues if any. the latest problem is a rapid rpm acceleration that despite the speed being under 45 it causes a screen to pop up that states (transmission temp high stop safely) flooded at random by another message saying( a condition with your engine control system has been detected and a full system check is recommended at your convenience) along with that , the air conditioner shuts off at random and fills the car with humid smelly air. they refuse to do anything @ the dealership except give excuses as these warnings and car behaviors come and go as they please and without the evidence they can't fix what is not visibly broken. as a struggling American I can't receive the treatment other makers give their customers and Hyundai has turned their back on American import buyers , and until someone dies this will not become a recall or a problem for them , so with that said , I am hoping that nhtsa can look into these issues as they are scattered throughout many forums and if something happens to me with this car that I am afraid of driving without a choice as I am a contractor for the ny tri state area, I now have this letter as proof of my complaint . ps , this car is readily available to be driven by any of your investigators if you desire to look further into this . I hope this letter can save some poor college kid or family from injury or the dangers of this car

when I am in heavy traffic where I am constantly stopping and going the car hesitates, like it is going to stall. When i push on the accelerator the car makes noises and doesn't accelerate like it should. When I accelerate to get on the highway it does the same thing. This has been an on going problem with this SUV since we have owned it. We have taken it to the dealership many times and other automotive places and no one can tekk us why it does this,

I was driving my car and heard a rattling noise. The car suddenly started stalling and it cut off completely. Fortunately it cut off seconds before I entered the roundabout at a very busy intersection and i was able to roll into a shopping center parking lot. It wouldnt start again. Currently my car is at Bob Mayberry Hyundai. They ran diagnostics on or around Nov 9th. As far as I can understand I would possibly have to replace the engine. I was told they have to take a picture of the engine with the valve removed and send it to Hyundai and he said Hyundai also need all service records and they would able to obtain them. My car has around 65000 miles so its no longer covered under warranty.

I have had an ongoing issue with my 2017 Hyundai Tucson since May 17, 2021. Like many other owners, I have recently learned about the recall on engines for the 2017 Hyundai Tucson. In the information with the announcement of the recall, the article stated, “The issue has caused at least 18 fires, but no injuries, according to documents from the U.S. National Highway Traffic Safety Administration”. I wanted to know if my vehicle was one of these 18 fires? If it was, I would like to know that I will be covered under this recall, and the engine in my vehicle will be replaced. I can begin to be reimbursed for the $1,000s of car rentals that I was told would be reimbursed before my warranty claim was denied. If it is not one of those 18 cars? Why not? I will give more information below on what happened to me and my car. Through further research, Attachment A on the NHTSA website states that “As of the date of this filing, Hyundai is aware of 45 fires related to the recall condition”. Once again, I ask if my vehicle is on this list? If not- why was it not after the engine fire and the below happenings occurred to me in May 2021. Happenings On May 17, 2021, I was driving home from work on Interstate 195 in New Jersey. My check engine light came on the previous week, and I immediately brought my car into an auto body to receive an oil change and a 25 point maintenance inspection. But, unfortunately, the check engine light went off. While traveling on the freeway at approximately 65 - 70 miles per hour, I could feel my acceleration beginning to get slower and slower and harder to use. I was pressing entirely on the accelerator, and the car continued to go slower Suddenly, the acceleration stopped completely, and all the lights on the dashboard went on. I noticed smoke started to appear from under the hood and from the tail of the vehicle. After nearly being hit by another car, I was barely able to get into the shoulder. I just so happened to break down on the part of

2017 Tucson Limited 1.6L power train malfunction due to vehicle’s dual clutch transmission. While accelerating, the vehicle frequently pauses, best described as a frozen hesitation of failed movement. During this hesitation, the vehicle’s RPMs will be very high. After approximately 3-6 seconds, the vehicle begins to move rapidly in a jerking motion, often with enough torque to push the driver’s back to the seat. This malfunction is extremely unsafe and scary, especially when it occurs while driving through intersections and when merging with traffic. The manufacturer has said this issue is only related to a computer update. There are no warning lights or alarms when this malfunction occurs. Recently, the check engine light turned on and now has a transmission error code: unable to engage first gear. This malfunction has occurred since I bought the new vehicle. For additional context, I change the oil every 4,000 - 5,000 miles, along with all filters and other fluids when recommended, and use quality gas. Routine maintenance has been performed by an independent repair facility. Services performed are protected by federal law from manufacturer implying or denying warranty service because of this (Magnussen-Moss Act, Title 15, Chapter 50, Section 2301-3312).

My vehicle had an engine failure. I was driving the Vehicle and suddenly the oil pressure light came on, loud noises came from the engine rapidly came after the oil pressure light, and the car stalled out within a minute of the oil pressure light coming on. Judging by the sounds, I believe there was a catastrophic engine failure. This situation appears to be exactly as described in NHTSA Recall # 21V727000. Since this recall was issued, Hyundai has not provided any notice to people that such a major safety issue had potential to occur. The vehicle has been towed to a Hyundai Dealership. However, neither the Hyundai dealership nor Hyundai can provide any meaningful communication other than they would begin their inspection of the vehicle in as soon as one month from when they vehicle was placed in their possession, however, given the exact circumstance described in NHTSA Recall # 21V727000 is what took placed, I find it difficult to believe that any other situation could have lead to this engine failure for a vehicle that is just approaching 50,000 miles

Purchased my 2017 Hyundai Tucson 1.6 Turbo SUV in mid-July 2021 from CarMAX. Brought it into their service department because it seemed like the battery was dying due to the car not wanting to start/turn over, or turning over veeeerrrry slowly, while holding down the push-button start. CarMAX replaced the battery and checked over the acceleration issues I also reported. At that time (July), the vehicle had also randomly opened it's trunk, with no outside communication to do so. At first I thought it was a fluke, but it's been happening so often lately (now October 2021) that now my husband is constantly checking to make sure the trunk is closed-because the key fobs will be hanging up/away from people/out of pockets but the trunk will still open randomly. TODAY, 25OCT2021, I got a phone call from my husband while I'm at work-telling me that while he was driving our son to work, the trunk decided to RANDOMLY OPEN WHILE DRIVING DOWN THE ROAD, spilling all the contents of my trunk out onto the highway!! This is clearly some kind of electrical issue, that I see other Hyundai owners have been experiencing since AT LEAST 2011-and not all Tucsons, either! When calling around to various mechanics (because the car is, of course, out of warranty), its going to be at least $150 to diagnose the problem (not including FIXING it), and I have to either sit and wait all day for the fix to be done (IF it can be fixed same day!) and be without my only vehicle. This seems to be a recurring issue with Hyundai vehicles, which is quite sad, because I've owned Hyundais before and they were WONDERFUL cars. I would hate to have reached the end of my relationship with Hyundai after seeing all the ELECTRICAL issues that seem to be popping up everywhere, causing fires, causing people's cars to randomly STOP and/or TURN OFF in traffic (have had that happen also, with a Toyota), vehicle FIRES, lights burning so hot they melt their housings, etc. THESE ARE *ALL* ELECTRICAL/WIRING HARNESS RELATED!

My back passenger door won't open from the inside. The door appears to be unlocked, but it doesn't open. I recently received notice that Hyundai has issued a warranty extension for the door latch on this model, so it's a known issue that's obviously quite common. It seems to me that a widespread door latch malfunction is a safety issue that would be better addressed with a recall. I appreciate that my current problem will be covered under warranty. But stories shared online from other owners would lead me to believe that my other doors are likely to fail as well, and the extended warranty is only good until 100,000 miles. That may sound generous, but if they know their door latch is faulty, they should be required to replace all 4 doors with a latch that's not likely to fail.

Car stalled with no warning/check engine lights. There is still no fix. I don’t want to keep paying on a car that is going to cause an accident while driving! I’m lucky I wasn’t going at high speeds when it stalled. My children and myself could have died! No one ever called to do any testing but they knew about the recall in July when they told me about it. I’m very concerned that this will happen again even if they do “fix it” this is a problem on multiple vehicles from Kia and Hyundai.

The wastegate on the turbo malfunctioned, causing the turbo to need a complete replacement. Prior to fixing the issue, the vehicle would not accelerate correctly. The vehicle was not capable of reaching highway speeds quickly. The engine warning light was on (low turbo boost) but it only came on once acceleration was affected. The mechanic shop has a photo of the failed wastegate and the bottom portion where it connects was completely broken off.
