The contact owns a 2019 Hyundai Tucson. The contact stated that while driving at 5 MPH, the vehicle slowed down. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the knock sensor needed to be replaced. The vehicle was repaired, but the failure recurred. While driving, a month later, the vehicle slowed down. The vehicle was taken back to the local dealer, where it was diagnosed that the knock sensor needed to be replaced. The vehicle was repaired, but the failure persisted. The vehicle was taken back to the local dealer, where it was diagnosed that the engine needed to be replaced. The engine was replaced. Additionally, while driving, an unknown vehicle crashed into the rear of the vehicle, and it continued to move forward. The steering wheel became stuck and was uncontrollable. The driver shifted the gears to park and neutral. The vehicle was idling high and low. The driver depressed the push-to-start button, but the vehicle continued to move and drove onto the lawn over a flower bed and fence, went across a two-way highway, slowed down, and stopped. The vehicle was towed to a body shop. A police report was filed. There were no reported injuries, fire, or air bag deployment. The manufacturer was contacted to obtain the EDR box, and they sent an engineer who reported that the air bags were not supposed to deploy and was unable to duplicate the failure. The failure mileage was approximately 1,000.
The drain plug was loose, even thought the mechanics ensured it was tightened. This is another case out of many of 2019 Hyundai Tucson owners who have found the drain plug to be faulty causing loosening and then falling out causing all oil to drain quickly and without warning. My engine unfortunately died mid drive while at the base of a large bridge, causing safety risks to myself and my passenger, as well as other drivers on the road. The engine lost so much oil at once giving no chance to even be warned about malfunction, as we were driving and it just fell out. My engine seized completely. This is not the first time Hyundai parts have done this, according to other owners, mechanics and other forums. Hyundai still has no recall for this faulty parts and offers no assistance to remedy a potentially life threatening situation.
The car barely has 50,000 miles on it and I had to replace all the tires rotors and brakes. Then a week later we were driving and it started making a funny noise and it would not drive more then 30 mph. I am going to have it towed to the dealership and see what the problem is. I have been reading about a lot of people with this same problem for faulty engine. I will sue them if this is the case this happened another time to me and I sued them under the lemon law
My car is burning oil like crazy, having to top off engine with 1.5 quarts between 5,000 mile oil change with synthetic oil. Took to Hyundai for oil consumption test. Let them know I'm having issues with burning oil, and my check engine light comes on often. They looked at my car saw enough of a problem according to advisor to skip first step of oil consumption test and jump straight to step 2 an engine combustion cleaning, which cause multiple more codes to come on. Drove the 1,000 mile 1378 to be exact because I explained to them that I couldn't bring back at exact mileage and was told that was fine. I was toldy car was only a quart low and that that meant everything was fine and that they would now honor the warranty. I am using in ungodly amount of gas and my engine oil smells like straight gasoline. I explained this to the manager and he said he resubmitted to try to retest again and was denied. I do not know what to do at this point. The advisor even said he didn't agree with their decision but it was up to them. His hands were tied. I am a single mother still paying on the car and only bought new because of the warranty. I provided immaculate proof of oil changes and maintenance. Please help ?.
The contact owns a 2019 Hyundai Tucson. The contact stated that upon starting the vehicle, he observed unusual RPM fluctuations and vibrations during idle, after which the check engine warning light illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the catalytic converter. The vehicle was not repaired, and the contact continued to drive the vehicle. The vehicle was later taken to an independent mechanic, who determined that there was a misfire in cylinder #4. The independent mechanic informed the contact that the failure was previously misdiagnosed, resulting in damages to the engine and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 100,000.
I was driving approx 55mph on [XXX] in my 2019 hyundai tucson when the check engine light came on and the engine started to stall. I felt the acceleration dying down in the middle of busy highway traffic. Gray smoke started coming from the hood cracks. I luckily was in the right lane already, so when I could I veered off to the shoulder and the car quit. The smoke was increasing badly. Ppl from the highway were yelling its going to blow up get away from it! I was so scared. I grabbed my phone and keys and ran as far as I could while dialing 911. Within a couple minutes flames were swallowing the entire engine and front of the car. I am furious. I researched online and hyundai has had many similar incidents with this car and other with this engine ! These need to be banned and taken off the road before they kill anyone else. Ppl have been injured and killed from similar situations just like mine. I thank God I made it out of this horrific situation alive. But now I have no car and am at risk of losing my job and then housing. I thought I would have this car for years. Now I'm traumatized and without transportation.

On 05/11/2024, I accelerated onto the freeway at which point my vehicle would no longer go past 50 mph with the pedal to the floor. I had my two small children in the car at the time. It was dangerous as cars around us were going 65+ mph. The check engine light started blinking when this was occurring. Prior to that the check engine light had been on because the dealership claimed they didn-??t know why it was triggering and that they have to take my engine out and replace it just to explore the issue. I don-??t have the money for that. It has a knocking sound, a pungent fuel smell and it still won-??t accelerate. I only have 85k miles on the car.
I was driving on the highway when my vehicle started decelerating and shutting down completely. I ended up safely pulling over because it could-??ve been a serious accident and called FHP they tested my car code p1326 came up I had it towed to the dealership where they assured me I had the extended warranty and that the car should be covered and I don-??t have to pay out of pocket. What the dealership told me would take 2 days has now been almost a month and still counting. I-??ve had 3 denials for engine replacement due to being outside of warranty with Hyundai even though I have the extended warranty. The dealership has sent pictures and spoke with my case manager at Hyundai to confirm that the engine failure was due to the bent connecting rod bearing that is again covered under warranty. They came back and said other codes populated showing the cause was not the rod bearing but that has to be false. One of the other codes was regarding coolant and I-??ve never had any issues with my car overheating or anything prior to my engine shutting down on the highway. I never had any flashing lights or warning signals on my dashboard. This was very unexpected and I refuse to pay for a repair that I didn-??t cause especially when this is consistent with Hyundai and their engines. This is a 2019 I should not have any issues. I need a solution quick
The contact owns a 2019 Hyundai Tucson. The contact stated while driving approximately 40-?"45 MPH, the vehicle failed to accelerate as needed. The vehicle failed to accelerate about 35 MPH. The vehicle went into LIMP/SAFE Mode. The check engine warning light was blinking. The vehicle was towed to an independent mechanic and the contact was informed that the failure was due to metal shavings being in the oil. The contact called the local dealer and was informed that there was no recall coverage on the vehicle. The dealer informed the contact about diagnostic testing the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was contacted and opened a case. The contact was informed that the vehicle was not covered under recall. The contact related the failure to NHTSA Campaign Number: 20V543000 (Service Brakes, Hydraulic). The failure mileage was approximately 92,000.
The components that failed are the engine and transmission and parts associated with the functionality of these parts. It is currently in the shop but will be available for inspection upon request once repairs are complete. My safety and others were put at risk when these malfunctions occurred (driving incredibly slow on the highway could cause an accident, accelerator malfunctioning that might break, broken down late at night hours from home, parts catching fire from leaking oil, etc.). The problems have been acknowledged by my warranty company and the two repair shops that have serviced it. My car was inspected by Geico Insurance Company after I got rear-ended and needed to file a claim, however, the inspection was not specifically on my engine/transmission. The warning dash lights didn-??t seem to come on until it was too late, especially during the transmission issue. I was driving around for days leading up to this issue thinking it was acting weird because it was due for an oil change but when I got one and nothing improved, I knew something was wrong. The check engine light did not come on until the car started to actively shut down and not move when I pressed the gas. The full detailed complaint is attached and receipts for repairs are available upon request. Attached is an overview of parts and pricing from the warranty company for the two claims.
I have to add oil to my every 2 days.. there is no leaks and I get frequent oil changes. Also acceleration to meet state limits my Rpm go super high not wanting to shift. Again no leaks and have checked so there is good transmission fluid in
Check engine light comes on it has come more then 5 times. I take it to the dealership. They tell me they are doing an oil consumption test this makes the 5th one. Lane assist when trying to move away from a vehicle it pulls back almost getting you into an accident.
I was having oil consumptions issues which meant I had to put a quart of oil in my car every 500 miles I drove. Then I was driving when my check engine light started flashing and now my car can't drive without shaking a lot. I can't drive it anymore.
I believe that this car is a lemon. Ever since we bought it we have problems with the engine not performing right. I have got the engine system cleaned multiple times one at the dealership and one at Valvoline Oil Change facility. The engine still didn't run smooth. I would always get the oil changed on time and the vehicle has never been in a accident. Now just yesterday the vehicle while driving on the highway just stalled and wouldn't accelerate past 60mph. Now the check engine light is blinking and all of the lights on the dash are on. Also lately sometimes the forward collision lights will come on and other warning lights and sometimes they wont. Another light that intermittently comes on are the auto hold and epb light and this has been happening since we bought the vehicle. I have taken into Hyundai and they basically were like yea sometimes that happens. I have not gotten the new check engine light checked but I am sure that it is something serious because the car won't accelerate past 60mph. I have read on other discussions that there are many problems with Hyundai engines and believe that I am victim to very poor quality manufacturing in this engine. I also have a 2013 Toyota Camry with 180,000 miles and haven't had one problem with it. This car is a lemon and would like to have some help with this please. I have also made a complaint with Hyundai under their drive train warranty.

On March 13, 2023 while I was driving at about 70 mph on PA route 66, the engine suddenly stalled and fortunately, I was able to move to the emergence lane. I turned off the power and restarted the engine, and it worked. This is the third time that I have experienced the same issue, with other two on I-376. I also couldn't start the engine after refilling gas, so I had to wait for about 15 minutes. I took the car to a dealership but the diagnosis did not show any problem. There was not error code at all. On the internet, several possibilities were mentioned, but I do not have any idea about the root cause.
I have a Hyundai Tuscon 2019, which was pre-certified by Hyundai. This particular car was part of a lawsuit because of a knock sensor issue. The lawsuit information is here: [XXX] The knock sensor failing is not really what causes the safety issue. The engine symptoms when the sensor fails is the issue. The engine goes into "safety mode" which limits the car to a significant slower speed. The problem is that Hyundai has now tried to fix this issue twice on my vehicle, and the knock sensor continues to fail. To be clear, they've replaced the sensor twice. Based on the lawsuit, the court mandated them to fix the knock sensor. They have done that free of charge, but the sensor continues to fail. To me this sounds like a manufacture issue. It is incredibly dangerous when you're on a highway and the sensor fails. It happened to me, and it was almost catastrophic. The car slowed down and there is nothing you can do about it. I noticed there was something wrong very quickly and put my hazards on. If I didn't, I may not be writing you here. You could easily get into a significant accident, and from that could lead to injury or loss of life. I am asking for a review of this. I have my service records as well as recorded conversations with Hyundai corporate regarding this issue. Service records are attached. I live very close to NHTSA HQ and willing to come in if necessary. To me, this is concerning enough for that..
