Won’t shift so that I can gain speed

The sunroof on my Hyundai Tucson will not close. Seems to be a motor problem. I brought it to a mechanic and it will be a lot of money to fix. I have looked up if this is a common problem and it’s all over the internet. I am not sure if it should be a recall. Thank you.

A few months back my car started to loose its ability to accelerate on the highway. I stopped to get my oil changed to see if that would help but the acceleration was still very limited. Now a month ago, my car started pouring smoke out of the exhaust. It was brought to a mechanic who said it was a turbo and or engine issue. I took it to a Hyundai near me for a clear diagnoses and they diagnosed it as needing a new turbo. I got a new turbo put into the car. My car worked for 1 day before pouring oil out of the bottom of it. I then had a new turbo put in. My car worked well for 1 week but now is leaking oil from the exhaust and making loud knocking, go kart noises. Most people I have talked to say it's the engine and that these problems are way too common in Hyundais well before 100k miles. My car has also been peeling white paint from the hood of my car for 2 years. I have passed hundreds of white hyundai's with the same paint problem.

On 10/5, after exiting the highway, check engine light began blinking. A loud cranking noise was present and the car began “puttering.” I immediately pulled over to find a parking spot. As I parked, the car seemed to stop running and the oil light turned on. I called a tow truck but since this occurred on the weekend, the dealer wasn’t open. Local mechanic stated it was the engine. I had it towed to Hyundai and it’s awaiting diagnosis.

When accelerating from a stop (particularly when taking a left turn across traffic, and uphill), the car often will hesitate and near-stall. It does not respond to driver “punching” the accelerator even to the floor, the car won’t respond, then suddenly catches and lurches forward. This problem has occurred since the purchase time in 2020 as a certified used vehicle from a Tucson dealer. I have reported the issue multiple times and ask the dealer frequently about it. They tell me no issue, never heard of it, no recall or repair. Online I see many people have reported this as a problem. It is definitely unsafe as drivers evaluate distance of oncoming cars in taking a left turn. When the car hesitates and doesn’t engage, time is lost to make the turn in time to make it.

The contact owns a 2018 Hyundai Tucson. The contact stated that while in a drive-through line and turning the steering wheel, the vehicle was shaking and vibrating. While driving at various speeds, the vehicle was violently shaking and lunging forward. The contact stated that the vehicle felt like it was running out of fuel. There were no warning lights illuminated. The vehicle was taken to an independent, who stated there was no engine light illuminated, but the mechanic replaced the coils, oil, and spark plugs. The contact called the local dealer and left a message. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 108,000.

Mileage: 108,000

My car was parked under the parking lot of my apartment. on Thursday morning 11am some one came in without any special took just with screwdriver within in 10 second they broke in my driver side door lock and damaged my door lock cylinder. and no alarm system turn on. this is completely unacceptable that the door lock is so fragile that anyone without any special equipment or tool can break in my car in 10 seconds.and if car is opened without the original key how come the alarm system dosent go on. it cost me 550 to fix the door lock cylinder and the central lock system plus i bought manual wheel lock and steering wheel lock because i dont trust security of hyundai.

My car was working fine since I bought it in April 2023. I passed inspection in November 2023. On January 24, after driving for about 15mins, my check engine light began flashing. The car would not accelerate over 25mph. I brought it to a dealership where it has been for 3 days. All communication about this problem was initiated by me, and the only answers I get are vague comments about testing.

Excessive oil consumption due to piston ring failure. Clogged catalytic converter due to metal shavings from piston ring failure. This put my safety and the safety of others at risk due to potential engine failure which disables all other safety features of the vehicle. confirmed by a hyundai dealership. inspected by a hyundai certified dealership. No warning lamps but oil consumption has been an ongoing issue.

I just purchased this car and I can't insure it in nys all of the insurance company's are claiming they black listed this car and can't insure it I'm not really sure how it's legal to sell somebody a 21000 car and you can't drive it because you need insurance in nys

Catalytic converter failure. Driving and vehicle slowed down while attempting to pass another vehicle in spite of foot being on accelerator. We were nearly hit head on by a semi trailer. Vehicle unable to increase speed over 50 mph. Taken to dealership. Diagnosed with problem with catalytic converter failure. The vehicle has 82,000 miles. Failure occurred suddenly. Vehicle has also been burning oil since June 2022. Dealership and Hyundai have covered nothing and offered no solutions other than to replace catalytic converter at cost of $3,693.35. There are multiple other complaints of exact same issue online and the safety of this vehicle is questionable as vehicle will refuse to accelerate suddenly which results in a dangerous situation for vehicle's occupants.

Lots of engine oil consumption And transmission since I bought car spend excessive engine oil and transmission fluid as well

Was told Hyundai is having a problem with motors and it’s burning oil quickly. There are recalls for it but not for my model and year. And my mechanic told me I have the same problem. Hyundai should extend the recall for 2018 Tucsons

The engine, rod bearing failure, constantly ABS Kits, Engine monitoring system (car is available for inspection). Our safety and others put at risk because the auto stopped dead on Interstate during rush hour traffic barely escaped death and seriously injuries to all travelers close to us. Towed it to a dealer for diagnostic testing who confirmed it's the engine and rod bearing system on report of inspection and estimate invoice. Manufacture told us to take it to a dealership and we took it to Wallace Hyundai of Stuart Florida. The warning was a knocking sound and oil light flickering just before auto began to sliw down to final stop. All took place on August 8, 2023. I have 7 photos to upload but your site is not allowing more than 10 documents. I tried to delete some documents but it did not have a delete function once I uploaded the documents.

Paint on the bonnet started peeling and flaking off. You can easily slide your finger on the edges of the paint and it will peel right off.

I have only owned the car for 1 month. I had gotten an oil/filter change and a new oil pressure sensor at ~80,100 miles. I had requested the oil sensor be changed because it would flicker on and off when the car was idling/low RPMs once it had heated up fully. This had fixed that issue seemingly. At ~80,700 miles the car had started riding a bit "rough", especially at higher speeds, so I decided to have a look under the hood. I was terrified to see that my dipstick was bone dry. There was never any evidence of any noticeable leak underneath the car on the driveway nor any evidence of blue smoke coming out of the exhaust. After some research (Hyundai corporate was telling me over the phone multiple times that there was no known issues with my specific car/engine) I was appalled to see I was essentially lied to. I found multiple official TSBs, NHTSA notices, and hundreds if not thousands of other customers noting the exact same experience. I had tried to take it to Hyundai for the oil consumption tests laid out in multiple TSBs but I was denied "due to the original warranty expiring". To my knowledge this exact issue has caused Hyundai and Kia to extend to 150k miles for all owners. This is my only mode of transportation and I am so worried my car will stall/seize/catch fire on the highway. This is beyond unsafe and unacceptable but I assume I may have to wait until the final litigation hearing in September for official recalls to be issued. If my car makes it that long.

Acceleration issue, from a stop position on a red light or stop sign, when the gas pedal is pressed the engine revs but does not move immediately, after a couple of seconds it lundges forward, also when trying to merge you must wait for a very big gap to safely merge, the car does not respond and this is very dangerous, Hyundai need to rectify this issue before someone dies.

I was driving, my oil and battery light went on, my engine stalled I pulled over. The car started to smoke and caught on fire. The car is totally a lost cause.

The oil plug fell out of my Tuscon while I driving on the highway and it burned out my entire engine on January 2, 2023, at approximately 5:40 pm EST. The tech at the dealership found the plug in the tray under the spot where the plug goes. It was inspected by a technician at a Hyundai dealership. The car is a 2018 Tuscon--had less than 55,000 miles on it and is now basically worthless and undrivable, quoted $13,000 to fix it. My entire engine now needs to be replaced. I was within the lifespan of my last oil change when the plug fell out. A red oil light flickered on and then a battery subsequently came on. Within approximately three minutes of the light first flickering on, the car was dead on the side of the highway. The car would not turn over once it was stopped on the side of the highway. The car is still at the dealership and available for inspection as of today, but I am not sure how long it will be there because I am not sure what is the best path forward in terms of repair because of the financial cost. I'm lucky that I was able to navigate my car onto the shoulder of the highway and secure a tow without injury. It was a very foggy day and it was already dark when this occurred and I was afraid I would be struck if I exited my car. My car drifted to a stop at the start of an exit ramp with a highway barrier that prevented me from going farther right onto the shoulder.

I’ve been having an issue with the car “jerking rapidly” when in traffic and rolling slowly and when climbing relatively small hills, it began about 2 months ago but have become progressively worse over the last month. I was told by someone with a similar vehicle that it is the “lower arm control. Need help with is or if there is a recall

check engine light comes on bout 25 times a week i plug my scanner into it and it reads knock sensor faulty I seen a RECALL for these cars why doesn't my car have a recall of this on going issue?

I have a Hyundai 2018. I bought it in 2019 with about 64,000 miles on it. I keep up with all the maintenance on my SUV. I noticed once I moved from Illinois to Florida, after having the car for a year, it started consuming a lot of oil. I've never had an oil leak anywhere on the car. In November of 2020 I went to Take 5 to get my oil changed and the mechanic said make sure to check my oil often because my truck burns a lot of oil. I'm find myself putting oil in my truck once a week. Every 500 miles it needs oil. The crazy thing is, is that the oil light never once came on. The engine light will come on. I went to a recall appointment 2 weeks ago, which was the same day I got my oil changed June 11, 2022, and I told them about this issue and they did nothing. By June 23rd I needed more oil! I see California has a lawsuit about this issue. I want to trade in my truck because this is costing too much money feeding this truck gas and now oil!

Recall was corrected via el cajon hyundai, however not updated with nhtsa website.

On 18 August 2021, I had a recall fixed on my Hyundai Tucson. The recall is now fixed, however Hyundai has not removed the recall record against the VIN. I have been trying ever since to speak to someone from Hyundai USA to get the recall cleared, however they refuse to escalate the issue internally and give no answers regarding how it can be fixed. I'd like to lodge a complaint because I am selling the vehicle shortly and need the recall to be cleared ASAP so that I can register and sell it.

Lag and than quick acceleration upon take off. RPM revs to2000, but power serge comes a few seconds later. Just bought this car, have not returned it for testing yet, but now understand Hyundai knows about this problem, but has no solution. Could be a hugh safety hazzard.

My car will excelerate with no warning

NO CARS WERE IN FRONT OF ME OR BEHIND ME... I SAW NO DEBRIS ON THE CAR OR IN THE ROAD... THE ROAD WAS PAVED.. I WAS REALLY AT A LOST AS TO WHAT COULD HAVE HAPPENED TO IT.. UNTIL I STARTED RESEARCHING ONLINE AND FOUND OUT THAT IT HAPPENS TO THESE SUNROOF OCCASIONALLY.. I AM WORKING WITH HYUNDAI NOW TRYING TO GET THEM TO REPAIR IT... IT REALLY SHOULD BE A RECALL...

HYUNDAI ISSUED A RECALL WITH A REPLACEMENT PART NEEDED TO PREVENT AN ENGINE FIRE. WHEN THE DEALERSHIP AND CORPORATE WERE CONTACTED, WAS TOLD THEY ONLY HAVE A REMEDY FOR THE 2019-2021 AND NO REMEDY YET FOR THE 2018 MODEL, WHICH IS MINE. SAID THEY CAN'T GUARANTEE THE CAR ISN'T DANGEROUS AND DEALERSHIP TOLD ME TO CONTACT CONSUMER AFFAIRS TO OPEN A CASE AND SEE WHAT THEY WILL DO ABOUT REPLACING THE CAR.

ONGOING ISSUES WITH THE ENGINE TRANSIMISSION. AFTER 3 DEALERSHIP VISITS, PROBLEM WAS DUPLICATED AT BOB MAYBERRY HYUNDAI-MONROE, NC. WE WERE TOLD THIS WAS A KNOWN PROBLEM AND "FIX/PART" WAS COMING IN MARCH/APRIL 2020. I WAS NEVER CONTACTED. CONTINUED TO DRIVE THE CAR UNTIL FINALLY GOT FED UP WITH THE SAME ISSUE. I WENT TO OTHER DEALERSHIP (KEFFER HYUNDAI-CHARLOTTE, NC.). WAS TOLD THEY HAD TO REPLICATE BUT TECH COULD NOT. (REPAIR INVOICE STATES THEY DROVE THE CAR 1 MILE!) (THE DEALERSHIP WAS TOLD THIS WAS AN INTERMITENT PROBLEM). THE PROBLEM IS WHEN DRIVING VERY SLOW IN STOP & GO TRAFFIC, THE CAR JUMPS SIMILAR TO SOMEONE LEARNING TO DRIVE A STICK SHIFT AND HAVE PROBLEMS WITH THE CLUTCH. I WAS AT A STOP SIGN ONE DAY...AT A COMPLETE STOP. I PROCEEDED TO MOVE FORWARD AND THE CAR STOPPED ABOUT 3 FEET AFTER MOVING. HAD I PULLED OUT IF THERE WAS ALOT OF TRAFFIC, I WOULD NOT HAVE HAD TIME TO MOVE IN THE ROAD. I DO NOT HAVE ALL INVOICES FROM FIRST DEALERSHIP (BOB MAYBERRY HYUNDAI-MONROE,NC), BUT THEY WILL HAVE EVERYTHING IN THEIR SYSTEM. I CAN REQUEST THIS DOCUMENTATION IF NEEDED.

ON SIX DIFFERENT OCCASSIONS MY VEHICLE HAS STALLED OUT WHILE REACHING SPEEDS OF UP TO 50MPH. I HAVE TAKEN IT BACK TO THE DEALERSHIP ON 3 SEPARATE OCCASIONS TO BE TOLD THERE IS NOTHING MECHANICALLY WRONG WITH THE VEHICLE. ON 8/25/3020 IT STALLED AGAIN AND CAUSED ME TO BE REAR ENDED. I AM TERRIFIED TO OPERATE THIS VEHICLE ON PUBLIC ROAD WAYS NOW.

THE 2018 HYUNDAI TUCSON SEL HAS AN INTERMITTENT ISSUE WHEN ACCELERATING FROM A STOPPED POSITION. THE ENGINE WILL REV UP, BUT IDLE FORWARD FOR ABOUT 3-5 SECONDS, UNTIL THE VEHICLE GOES. THIS DOES NOT HAPPEN CONSISTENTLY. THE DEALERSHIP HAS RESET THE PROGRAMMING ON THE TRANSMISSION 2X. THERE ARE OTHER INDIVIDUALS ONLINE THAT ARE EXPERIENCING SIMILAR INTERMITTENT ISSUES WITH THEIR 2018 HYUNDAI TUCSON. IN JUNE 2019, I WAS ALMOST STRUCK BY A VEHICLE WHILE I WAS COMPLETING A LEFT HAND TURN ON GREEN WHEN AN ONCOMING VEHICLE DECIDED TO RUN THE LIGHT. THIS HAS HAPPENED NUMEROUS TIMES. ON 10/7/19 - I BROUGHT IT BACK TO THE DEALERSHIP AGAIN TO RIDE WITH A TECHNICIAN. DURING THE 30 MINUTES RIDE, I FELT LIKE I HAD REPLICATED THE ISSUE SLIGHTLY BUT THE MECHANIC ONLY ASKED ME WHAT KIND OF CAR I PREVIOUSLY DROVE. WHEN I CHECKED OUT OF THE DEALERSHIP, I ASKED FOR PAPERWORK TO DOCUMENT MY ENCOUNTER, EVEN IF THE MECHANIC CLAIMED IT WAS UNFOUNDED - BUT WAS NOT PROVIDED WITH ANY AND TOLD THAT THERE WAS NOTHING TO DOCUMENT.
