general problems of the 2016 Hyundai Tucson - part 1

Car often does not accelerate when hitting the gas. Was turning onto highway from a stop car did not accelerate causing other vehicle to swerve to avoid hitting me as my car would not move. Couple seconds later it moved.

As I was driving I was stopped & told my car was on fire. I immediately stopped & hopped out & less than 30 seconds later half of the hood caught heat/fire & flew into the windshield breaking it. At least half the car is burnt to ashes.

Engine ran out of oil with no indication on instrument panel that it was happening. Engine now knocks and needs replacing. My independent service center has determined a failure. It is available for inspection.

Part(s) affected: engine / engine control / stall / loss of power summary: my 2016 Hyundai Tucson (VIN: [xxx] ) has an active p1326 – knock sensor detection system (ksds) code, which indicates rod bearing wear and imminent engine failure. The vehicle experiences: •loss of power •inability to accelerate •engine hesitation •risk of stalling while driving these are serious safety risks. This issue is part of the Hyundai/kia engine defect settlement xxx), yet Hyundai refuses to provide towing or address the safety risk despite the p1326 code being a known precursor to engine seizure. The vehicle is currently unsafe to drive, and Hyundai customer care has refused to escalate my case according to settlement requirements. This is a safety hazard that can cause engine seizure and sudden loss of power while driving. Details: •Hyundai case #: xxx •engine settlement code p1326 confirmed •Hyundai refusing proper support •vehicle should not be driven NHTSA intervention is needed due to Hyundai’s failure to address a known safety defect.

Dear NHTSA, I am submitting this complaint to report a recurring issue with oil consumption in my Hyundai vehicle, which I understand is a known problem affecting this particular engine type and model. I am the original owner and have been a loyal Hyundai customer for many years. I have followed all recommended maintenance, including regular oil changes. Despite this, my vehicle has developed excessive oil consumption that has not been resolved through standard service procedures. The dealership has contacted Hyundai for approval to perform a combustion chamber cleaning, but based on my research and feedback from other owners, this procedure does not effectively address the root cause of the issue. My concern is that this problem may be indicative of a broader mechanical defect that could impact engine performance and safety. My 10-year warranty is nearing expiration, and I am worried that delays in resolving this issue may result in the loss of warranty coverage for necessary repairs. I believe this issue warrants further investigation, as it appears to be affecting multiple vehicles with the same engine configuration. I respectfully request that NHTSA review this matter and consider whether a broader safety investigation is warranted. Thank you for your attention. Sincerely, kelly stafford.

For about a year I have had issues with my car not accelerating in stop and go traffic. I push the gas pedal and it moves a little then will not go for about 20 seconds. Sometimes the engine will flutter. I have taken it to Hyundai and was told no diagnostic codes show and they can't find anything wrong despite bringing the reports from my auto shop of these things occuring. My car is going in yet again this week because this issue continues to get worse and I have almost caused several accidents in traffic due to not being able to drive. There is a recall however Hyundai says my car is not in the recall despite the same issues the recall is for. I have all routine service done when needed and have taken care of this vehicle but I feel like Hyundai should step up because this is very dangerous not only for myself but other commuters as well. The Hyundai dealership literally said they just have the sign on their building they don't support these issues.

I leased a 2016 Hyundai Tucson from metcalf auto plaza [xxx]. Every week since then I have had to return the car for repairs. It got to a point where neil suggested he can trade it for another but each and every vehicle I test drove to replace my car was not ready to be on the road but according to them every car had just got out the shop. Instead of trying to have issues resolved the mechanics decide to make "jokes" as if your pain and suffering is a joke. Since I did not want a trade in and wanted my car fixed instead neil tried to tell me that this was my final offer which I declined because why not just fix my car? I went to talk to neil in person September 9, 2025 about getting my car fixed and the frustrations I am having because having to return the car weekly and I havent had it for a month is outrageous. [xxx] I was driving the Hyundai on the highway with my children in the car and the electricity to the car completely cut off but came right back on, I got off the highway and the car did it again and this time the wheel locked up and I almost wrecked the car. I called metcalf and the only thing they could tell me was they can tow my car to metcalf but me and my children had to find our own means of transportation. Every time I called to have my car serviced and told them about what I would hear and feel they could never make the car "do it again". I am beyond frustrated, upset and terrified because I have been telling them about smoking coming from the engine, rattling noise etc. My kids lives were put in danger and the only thing they could say was "I apologize and we can tow the car to the shop". Did not care if we had transportation and have never offered to give us any after continously getting stranded in the car. Now the car is towed to their shop once again and the car wouldnt even turn over for me to get it out of the middle of the street. I was blocking traffic and had to have the police block information redacted pursuant to the freedom of information act (foia).

The reason of this complain is due to excessive oil consumption which now damaged my catalytic converter against Hyundai motors America. The complained started 2021 where we noticed that the low oil engine light up after only 1500 miles from last oil change. We submitted the complained with dealer (carlsbad and escondido CA) and my car failed 3 consecutive oil consumption test and Hyundai performed an engine cleaning, claiming it was going to fix the problem. This happened when the vehicle was still under warranty. At the time they said that if this did not fix the problem, they were still going to fix the car since the issue happened under warranty. The engine cleaning did not fixed the problem, my car no longer has warranty and my catalytic converter fails and makes the vehicle inoperable in highway (engine ceases to accelerate) . We submitted a complain with Hyundai corporate and they denied fixing our car since the vehicle was no longer under warranty. I would like to ask for them to fix the engine and catalytic converter make the car operable again.

Brought vehicle in on 07/10/25 to dealership with very low oil, it was determined vehicle was burning oil and combustion cleaning was recommended. Hyundai corp. Denied claim due to 2nd owner. We are not 2nd owner had to transfer title upon my father's death, vehicle owned by family. Hyundai then approved claim and combustion cleaning was done. We were then told by dealership to bring in vehicle every 1000 to check oil. On 2nd 1000 check it was determined to be burning oil and needed engine replacement. Hyundai corp. Denied claim this time stating gross maintenance neglect from 01/2018-06/2019 period but only 3084 miles were put on between oil change. This was not brought up during combustion denial. Also Hyundai stating out of warranty which expired 08/24/25 but issues started in 07/2025. I have asked Hyundai case manager to provide written proof in owner's manual where it shows we did not maintain vehicle in accordance to manual.

Engine has rod knock and low power due to rod bearing failure. There was never an illuminated oil light or message of any sort prior to failure. This vehicle has had oil changes regularly and never been an issue till now. With Hyundai not having a recall on this engine, and seeing many other reviews about this same issue it is a very dangerous issue leaving people stranded and loosing power in times where serious harm issues could occur and this issue is very costly being that the engine will have to be replaced. As a consumer taking care of the vehicle and still the engine failing due to the lack of integrity of Hyundai I believe Hyundai should step up and make it right and take care of the people who have spent there hard earned money on these cars and are now left in the dark.

Me and my daughter were headed back home from a family trip and we were stranded on the side of the road luckily we had family tailing us!! my engine light came on while we were still in the city in savannah so we stopped by an autozone and changed the spark plugs so the engine light stopped blinking but when we got about 20 miles from home it stopped going we had to pull over it started smoking and it was really hot but the temperature had never moved we had it towed home!! I keep my maintenance up regularly on my car I had 2 mechanics check it out they both said the piston is breaking the spark plugs and it’s something down in the motor that’s doing it I should not have any motor issues at all with my car!! especially when I do my part at keeping it up I was quoted 7,738 to fix my car which I don’t have both mechanics said the engine in those cars are no good and it’s been recalls on them just not my model it’s not right I’m out of a car and no way to work or no way for my kids to get around they have to ride in lyfts and ubers with strangers I feel like my car should be fixed because I did my part at keeping it up and I’m still out of car and frustrated due to the companies negligence!!.

While driving, on multiple occasions all warning lights will come on and the car will start to lose power. The headlights constantly go off and come back on randomly. Turn the blinker on and the rear window wipers intermittently come on. The vehicle has been towed to the dealership so many times and we either get “can’t duplicate” or needs oil change, which had just been done. Now we are being told that we need a second engine replacement. Unfortunately this time it will not be covered by warranty. We have reached out to Hyundaii motors 3 times and the bbb auto but they stand behind it not qualifying for the lemon law. Hyundai should have some obligation as all these issues are “known issues” just not recalls. The 2016 Hyundai Tucson is not a safe vehicle.

Was driving down busy road when engine suddenly knocked violently and shut off rendering car inoperable. Inspection revealed low oil, despite not being due for an oil change after and no visible/identifiable leaks. Investigation by mechanic resulted in being told that numerous Hyundai engines like this are having the same problems and need total engine replacements. The call only had 70,000. Dealership said they see one a week.

Misfire, excessive oil consumption, engine knocking, loss of power/acceleration, gas smell, excessive gas consumption.

Was driving down busy city road when engine suddenly knocked violently and shut off rendering car inoperable as traffic had to go around my disabled vehicle. Inspection revealed low oil, despite filling 4 weeks prior after change and no visible/identifiable leaks. Investigation by mechanic resulted in being told that numerous Hyundai engines like this are having the same problems and need total engine replacements. They said that they "see this at least once a week in these Hyundai's and kia's". There were no warning lights or anything prior to the event.

My catalytic converter caught on fire a couple months back then I hit a code for the knock sensor replaced it and it started to act up again I can’t go over 49 burning oil took it to Hyundai now they are saying my engine is going out and I’m still panting carmart got the car.

Total engine failure. Per dealership mechanic, random misfires on all cylinders with a dead miss on 4.

Excessive oil consumption.

Excessive oil consumption which has then in turned caused my catalytic converter to go out.

I’ve been having ongoing issues with my 2016 Hyundai Tucson where the car struggles to accelerate, especially after stopping at red lights or pulling out into traffic. Sometimes, when I press the gas pedal, the car either hesitates badly or doesn’t move at all. A few times it’s completely stalled while trying to make turns or cross intersections, which has been really scary and dangerous. I did some research and found there was a known recall for this exact problem related to the transmission control module software and the dual-clutch transmission. The symptoms described in the recall match mine perfectly, but when I checked my VIN, my vehicle isn’t included. I haven’t taken it to the dealer yet because I’m worried I’ll have to pay out of pocket for something that I believe is part of a known manufacturer issue.

Fuel injectors no warning…went to get breaks checked, while they were checking them the engine light turned on after that they couldn’t get my car to start again.

I reported the vehicle to dealer for above oil consumption, which they confirmed with service check of oil level. Vehicle often stammered and failed to accelerate upon purchase. This vehicle stammered and engine began to smoke. Vehicle could started first, turned unit off. Vehicle is being towed to shop for diagnostic results.

The contact owns a 2016 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the vehicle shook abnormally with several unknown warning lights illuminated. The contact noticed an oil odor. The vehicle was driven to the residence. The contact's father, who is an independent mechanic, inspected the vehicle and diagnosed the vehicle with oil consumption and engine failure. The contact was advised that the engine needed to be replaced. The vehicle was not repaired. The contact was advised to monitor the exhaust for smoke and add oil daily. In addition, two days later the contact attempted to start the vehicle, and the vehicle started after several attempts. The was an abnormal oil odor entering the vehicle through the vents. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 107,000.

The vehicle does not accelerate entering roadway, transmission replaced in 2022, catalytic convertor replaced in 2024. Several instances occurred when entering highway vehicle lost power and failed to merge safely, ultimately requiring hasty exit to roadside to avoid collision. The vehicle was purchased used but has been a safety risk since purchase date. Originally diagnosed transmission, then catalytic convertor, then knock control sensor. Engine oil is replaced more often than routine maintenance and refilled in between oil changes. Autonation Hyundai mall of georgia originally assisted with transmission replacement Feb 2022, catalytic convertor was replaced in Mar 2024. The vehicle has been parked for considerable time while insurance and car payments continue. In Feb 2025 my daughter was driving and was nearly rear ended when vehicle failed to accelerate, it has primarily parked since that time while exploring repairs. Car fails [xxx] enroute to game. Last quote to repair catalytic convertor was total automotive in gainesville GA. Around 19 may 2025. I believe this vehicle poses a significant safety risk due to acceleration delays, all attempts to resolve have been unsuccessful.

1. "transmission or ecu" 2. There is a lag and sometimes almost stall when accelerating from a stop. I was turning into a lane from a stop sign and the car decided to not move for 3-4 seconds after pressing accelerator. If people had come around the blind corner when that happened I would have been t boned. 3. All four people living in my house. . . . . . And our mechanic. Yes 4. No, because were not paying for something that has had a recall. 5. We inherited this car from my grandmother and she knows nothing about cars so she never thought anything was wrong. Since the day we got it, it has been doing the same thing "dct control logic update & p0128 dtc logic update (recall 149)" #17-01-023.

Engine is burning oil and has been for sometime. Won’t accelerate and sputters tie rods are worn out. This car is a lemon and dangerous to drive.

All my doors stick and sometimes I have to fight with my car to even get a door open. Also, when trying to accelerate sometimes my throttle response is slow and I will not move for a few seconds.

My 2016 Hyundai Tucson has a severe engine defect that causes excessive oil consumption and poses a safety risk while driving. It constantly throws the p1326 engine issue, which is the knock sensor. The issue is not due to any misuse or neglect on my part. The vehicle consumes approximately one quart of oil per week, and I have been advised by two different Hyundai dealerships not to invest any money into repairs because the engine should be replaced under Hyundai’s extended engine warranty (15 years/150,000 miles). Despite multiple attempts to get the issue resolved over the past year, Hyundai continues to deny the engine replacement, leaving me with no resolution and forcing me to drive an unsafe vehicle. The engine burns an excessive amount of oil and needs frequent refilling to prevent damage. The vehicle has stalled and runs rough at times, creating a safety concern. Both Hyundai dealerships I’ve visited confirmed that this is a known issue and advised me not to spend money on repairs since the engine qualifies for replacement under the extended warranty. Hyundai corporate continues to deny coverage and has not repaired or replaced the engine despite the clear warranty terms. The issue has persisted for nearly a year, and the vehicle continues to deteriorate. I believe this defect poses a serious safety hazard because the engine can fail without warning while driving. The excessive oil consumption also increases the risk of engine seizure, stalling, or fire. I am currently forced to operate the vehicle in unsafe conditions due to Hyundai’s inaction. I am requesting that NHTSA investigate this ongoing engine defect and Hyundai’s repeated denial of warranty coverage for affected Tucson models. Owners should not be forced to drive unsafe vehicles or pay for repairs that should be covered under Hyundai’s extended.

Three weeks ago my dash board lit up like an orange christmas tree, with "abs failure" warnings. I found the Hyundai recall notice in our car file. It said that when the dash warnings appeared, the danger of an engine fire was imminent and that should contact the dealer that I bought the car from (Hyundai motors- naples, florida-USA). I did so. Personally. An appt. Was scheduled. This morning (fri. 11/15/24)upon arrival, a pleasant young woman informed me that Hyundai sent out lots of notices like this, but they didn't apply to my vehicle. I showed her the recall notice with my car's VIN number printed on it. She went back to her boss who told her "we fixed that for him three years ago," now, I am not certain of anything, but I never brought the car in for an abs system fix three years ago. I didn't know that I even had an "abs" system until three weeks back, when the dash board lit up. Politely, I asked the young woman to bring my car back out, as we were done. She offered to make another appointment to "look" at the dash indicators. " I said" no, we are done. " so, now what do I do? is the car safe to drive or not? I own and operate an older Hyundai santa fe as well. I would be appreciative of your advice. Thank you in advance for your cooperation. The Tucson is a good car. I just don't want it to blow up on me. [xxx] , florida-USA information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

In April of 2024, I bought my 2016 Hyundai Tucson for a certified dealership in FL. Within 2 months the car began shaking and I had to take it to have spark plugs replaced which cost several hundred dollars. Shortly after that in November 2024, I was driving on the highway to school when I got an ‘engine overheating alert’ and immediately pulled over to turn off the car. After waiting for a few minutes to let it cool down and noticing that the coolant was very low, I added some more coolant in and tried to restart the car, but it would not turn on. I had to get a tow truck to a repair shop to which they informed me that the headgasket had blown and it would cost about $12,000 to replace it. Ever since, my car has been towed to multiple Hyundai dealerships and repair shops when I sought after answers as to what happened and one told me that the engine was known for eating oil too quickly, causing it to blow. I bought the car only for $16,000 and would have to pay about the same amount just to fix the engine and reading multiple reports online have shown from other others having the same exact issues with no answers and being stuck. We have had it sitting in our garage ever since and still do not know what to do.
