I took my vehicle to my mechanic for inspection check up. My mechanic told me and supplied paperwork from their scans that the P0420 sensor in the cat converter was shot again (3x in 5 years) and needed to be replaced. The engine light had come on 3 weeks beforehand and I had it read and knew what it was. They sent me to Hyundai dealer as it was under warranty with documentation. I get to Hyundai dealer tell them it needs the sensor for inspection and an investigation for oil leaking from back of the engine. I also told them I was adding 2-3 quarts of oil between oil changes. They told me my mechanic over filled oil by.5 quarts and that's why the engine leaked. They investigated after I disputed by saying an oil change had been performed the day I brought it to them and found a bad head gasket, fuel pump seal, and oil pan seal. They charged my extended warranty for those repairs, shut off engine light for cat converter sensor without replacing it, and made me do an oil consumption test of 1000 miles. Car was still not inspected at this point. After 35 miles check engine light comes back on. Cat converter sensor P0420. I take it back in. They tell me they won't replace it until the oil consumption test is done because they need to know if oil is coming through the exhaust pipes (it was). I complete the test and go in. They tell me engine is burning.5 quarts of oil/1000 miles which is acceptable and as long as I complete oil changes every 5000 miles I will be fine. They then tell me if I want sensor replaced I'm 800 miles over warranty so I have to pay $2400 to replace. Called corporate they're only willing to cover half the repair as "good will" for the cat converter and was quoted $1300 by the dealer in question. Almost a month and still not fixed and still can't get car inspected because the check engine light is tripped by the P0420 sensor in the cat converter. It's the only vehicle my family has. I'm forced to pay to have transportation.
- replaced catalytic convertor twice - Check engine light on, needs another catalytic convertor - Exhaust fumes are coming back into my car through the AC vents, I-??ve had to pull over due to being nauseas and extremely dizzy. - The dealership will not answer my phone calls, but will answer another phone because I have called from another phone and they picked up immediately - Was told from a service advisor that they would not help me -?? unless the car blew up -?? - My car did recently,8/8/24, shake aggressively, the check engine light flicked rapidly and a strong puff of fumes came through my car - They will not help me because they stated that my rod bearings are not rotted therefore I do not qualify for assistance and everything would come out of pocket, the engine replacement, the catalytic convertor due to me being a few thousand miles outside of my 100,000 warranty. - I have the invoice stating oil is leaking profusely out of my engine - I was told within the last 2 weeks that if my car was to actually seize, Hyundai is not responsible bc when they kept telling me to bring my car in, they kept diagnosing it so they quoted me at about $5k to fix everything.
-??ve replaced the catalytic converter two times, the check engine light is on so it says I need another catalytic converter, that was in June 2024. The car was at the shop yesterday, needs catalytic converter and oil is pooling all throughout the car, fumes from the exhaust are coming back into the car which makes me physically ill. The engine revs and slows down by itself, it goes through oil on such a regular basis that I have to carry a full size jug of oil with me at all times because I need to put it in before I leave work and when I am on my way back home, the dipstick will be dry.
When u try and pull out in traffic the Car hesitates and kicks to pick up and go. Had a few mechanics look at it and was told it is the Torque Converter With the Vehicle only having 19,000 miles on it.it is a huge safety issue and Hyundai is saying my Tucson has no warranty on it. So what I till crash and sue Hyundai?

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.

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 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
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..

The vehicle was repaired under the major engine failure recall. Took the dealer months to replace the engine and now they are reporting the transmission is bad too. The car had absolutely no issues pre engine failure leaving me stranded. From reading up on forums I think transmission failures are just as common as engine leaving you stranded on a busy highway.
The check engine light goes on and off every few weeks and it would stay off for a few days! The last code I had was P0420 that came up and I had a different one before that and it was for the catalytic converter! So I had already made the appointment to get it checked out and it was a faulty catalytic converter! Luckily my car is still under warranty I didn-??t have to pay out of pocket! Had the catalytic converter changed last year and again today almost a year apart!
I-??m traveling for work and I have only had to car 11 months. I have 52,000 miles on it and today tracking home my car engine light came on and my car wouldn-??t shift through the hills in Missouri. It got so bad after 1 mile of the engine light flashing at me that I had to stop in a construction highway with one lane and stop all traffic to let my car cool down for almost 15 minutes and I started it up and it would not go over 10 miles a hour. With my flashers on I got off the next exit and ran a diagnostic at O-??riley-??s in St. James Missouri. My codes are reading CAMSHAFT IGNITION CONTROL (P000B) and IGNITION CONTROL MODULE COMBUSTION QUALITY INPUT SIGNAL (P1326)

The contact owns a 2019 Hyundai Tucson. The contact stated while in her daughter's possession, the engine had failed to start after multiple attempts. Several warning lights illuminated the instrument panel during the failure. The vehicle was jumpstarted and the horn began to blare once the engine restarted. The vehicle was taken to a dealer where they were unable to determine the failure. The contact also stated that the vehicle would rattle while both idle and upon activation of the AC. The manufacturer was notified of the failure and the contact was given to a case manager; she was later instructed by the case manager to take the vehicle back to the dealer for assistance. The vehicle had yet to be repaired. The failure mileage was approximately 23,000.
Engine failure due to connecting rods issue. Engine began to smoke while driving with no warning, had complete engine failure and had to have vehicle towed to dealership.
While driving down a busy road at 10:00 pm on New Years Eve, my vehicle's engine completely shut off. Immediately prior to the shut off, the vehicle's dash displayed the oil and battery lights. The vehicle's automatic emergency brake and steering wheel lock were both engaged, not allowing me (or the tow truck company) to move my vehicle out of this busy road. My car remained in this location for 3 and a half hours. The hazard lights stopped working after the first hour, making it extremely difficult to see that the vehicle was stopped. After the second hour, an officer parked behind my vehicle with their lights flashing as he said it was an extremely dangerous situation and my car was sure to be hit. He was able to get a tow truck to me before Hyundai. For hours, numerous people were forced to brake quickly/swerve into other lane to avoid hitting my car. This occurred right before an intersection, putting 4 directions of drivers at risk of collision. I stood in the rain, near my car, attempting to help direct drivers away from the lane until the police officer showed up. The vehicle is now at the dealership which confirmed engine failure, pending replacement. Possibly related, this vehicle had the catalytic convertor replaced 3 months prior. It is not yet confirmed if this contributed to the engine failure.
Purchased the vehicle in June 2021 only had 1 previous owner. The dealership stated it was a pre-owned certified used vehicle that had just been inspected and service. Within the first month I had to take it back for multiple issues most recently the catalytic converter to be replaced and the Engine. I haven't even owned it let alone driven it long or far enough for either of these parts to need service or have failed. It's not even time for my first oil change that how low the mileage is that I've put on it. The dealership originally told me they never head about the complaints regarding the engine now they are trying to stiff me on selling me a lemon by charging me 3000 and telling me Hyundai isn't willing to cover the repairs. If this is a known issue which is seems to be a recall should now be issued.
Going up a hill, "Check Blind-Spot Collision Warning System" alert, clunk sound, rpms revved high, power lost and did not shift gears. 2 occurrences. Approximately 40,000 miles.
