general problems of the 2017 Hyundai Santa Fe - part 1

Was driving down road car went into limp mode about caused a big wreck, check engine was flashing and heard a loud noise as I was trying to get to safety. Had the car scanned and was for code p1326 and looking at all the recalls nothing is for the 2. 4l but y'all have been having a lot of issues with these theta 2 engines.

My son was driving the vehicle normally. There were no issues, warning lights, abnormal feel to the drive, and no odd noises. Suddenly, all of the warning lights on the dashboard lit up, acceleration dropped and he could no longer accelerate. He pulled off the main road and there was a burning smell and the vehicle was inoperable.

Component/system failed: engine assembly (theta ii 2. 4l gdi) and exhaust/catalytic converter. Description: the vehicle suffered a failure associated with the known theta ii engine defects. Engine oil consumption and internal engine wear directly led to unburned fuel and debris entering the exhaust stream, resulting in severe catalytic converter restriction/failure. Safety risk: the combined failure caused sudden loss of power while driving, engine stalling, and significant driveability hazards, creating an immediate risk of a rear-end collision on public roads. Confirmation & inspection: the failure was confirmed and diagnosed by a certified service facility. Replaced components and diagnostic documentation remain available for inspection upon request.

My truck began emitting a strong oil odor on xxx. I took it to amato in [xxx], where I was told the oil pan was leaking. They replaced the oil pan, and I paid for the inspection as well. About an hour after picking up my truck, the check?engine light came on. I returned to the dealership, and they then said additional repairs were needed, even though I had already paid $2,211. 57 for the work they claimed was necessary. At that time, my truck had 145,776 miles on it. Because the manager at [xxx] refused to address my concerns, I was told to go to another amato location, and I was effectively blacklisted from the first dealership. I went to amato glendale, where I experienced the same issues. They fixed only one of the problems, and that was only after I contacted Hyundai corporate. My truck continued to have oil?consumption issues. Amato required me to complete a three?month, 1,000?mile oil consumption test before they would consider providing assistance. I completed the test as instructed. Now, however, they are saying that due to the age and mileage of my truck, they will not cover the engine replacement — even though the problems began at 145,000 miles, not 156,000. Other drivers have reported that Hyundai delays necessary repairs until major engine damage occurs, and I believe that is exactly what has happened in my case. There was also a suspension recall that applied to the 2018 model but not the 2017. Amato Hyundai covered part of that repair only because I contacted corporate again. My current complaint is about the failing engine and amato Hyundai’s lack of responsibility in properly diagnosing and repairing my truck. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Cold-start hesitation & rough shifting: following the 9c2 ecu update, my vehicle is experiencing a brief period of throttle hesitation, rough shifting, or jerky transmission behavior specifically during cold-start operations.

Vehicle was brought to an authorized dealership for service, and while there campaign 9c2 (ecu software update for theta ii emissions improvement) was performed. Immediately following this software update, the vehicle developed drivability degradation, specifically engine stutter/hesitation and rough transmission shifting during cold starts. When attempting to accelerate in the first few minutes of driving, the vehicle delays engagement and then suddenly surges or lurches forward unpredictably. This creates a safety hazard, as the unpredictable power delivery and lag prevent the vehicle from accelerating safely when merging into traffic or turning across oncoming lanes, placing occupants at an immediate risk of a collision. The software logic error is fully reproducible every time the vehicle has sat long enough to cool down. The dealership confirmed the update was applied. There were no warning lamps or symptoms prior to the 9c2 update; the failure was caused directly by the manufacturer's campaign software modification to the engine control unit (ecu). The vehicle and its ecu are available for inspection upon request.

My 2017 Hyundai Santa Fe, purchased new from lynnes Hyundai in February 2017, has approximately 93,000 miles. The vehicle previously developed a significant oil-consumption/engine problem that was diagnosed by Hyundai, and Hyundai replaced the engine with a remanufactured engine. Approximately two weeks after the engine replacement, the check-engine light illuminated and dtc p1326 was identified. The dealership replaced the knock sensor. Approximately two weeks later, the check-engine light illuminated again with a recurring p1326 condition. The vehicle is currently at lynnes Hyundai and has been there approximately three weeks while they attempt to determine the cause. Hyundai techline is involved. Prior to the current repair visit, while traveling approximately 60 mph, the vehicle experienced a very forceful hesitation that jerked the vehicle. I immediately slowed down and pulled onto the shoulder. The vehicle continued to hesitate intermittently while I drove slowly to safety. I was concerned that the vehicle could lose power or shut down while I was driving at highway speed, creating a risk of a crash. The recurring p1326 condition has been confirmed by the Hyundai dealership. The vehicle and engine have been inspected by Hyundai/lynnes Hyundai multiple times, including after the engine replacement. The current recurring condition has not been resolved. The check-engine light is the warning lamp associated with the current condition. I do not know the underlying cause of the recurring p1326 condition; Hyundai is currently attempting to diagnose it. The vehicle is currently available for inspection at lynnes Hyundai.

There is a class action lawsuit for the theta engine in some kia and Hyundai vehicles and my type of vehicle falls into this lawsuit category. I drive a 2017 Hyundai Santa Fe sport and what the lawsuit described what happened to my vehicle, it seized up and you’re supposed to have a lifetime warranty for this problem. I submitted all the paperwork and norman Hyundai sent videos it was seized up but denied my claim so I have a car that no longer drives with a car loan still so can’t buy a new vehicle. I was told they didn’t see oil additive anytime but their own business this in March ‘26 and may ‘26. It states on the lawsuit if anyone’s in the class action lawsuit they are covered if this happens to your vehicle. Also, part of the lawsuit is the oil consumption and how much it’s eating gas and then it seizes possibly or catch fire and my car was barely getting a 1,000 miles and it would be empty so couldn’t keep up always checking it and the car seized up due to what’s supposed to be covered.

I took my SUV to get the 9c2 recall on 8/7/2026 performed and took it home. The next morning when I cranked it and left my driveway it acted as if the vehicle didn't recognize that I was pressing my accelerator. It sputtered and hesitated acceleration for about five minutes. It also acted as if it was not going to change from first to second gear. After about five min. Of playing with the gas pedal it straightened out. Twice I was almost hit by other cars expecting me to pull away from a stop sign. I took it back the next day telling the service agent what was happening and he kept it overnight. I received a text saying the technician was unable to find a cold start problem and it was ready to pick up. I was so mad I could barely hold my temper. I took it home and for the next week every single day it acted like this when cold started in the morning. I took it back to premiere Hyundai of harvey and was treated rudely this time. They acted as if they never had a single other complaint and told me I might have to leave it for several days so they could cold start test it for several days. This was on a Wednesday morning 8/19. I was never updated or called and when I texted my service rep on Monday 8/24 I was told the tech was not able to duplicate the complaint and to come pick it up. I will not ever buy another Hyundai because of the way I was treated and lied to. Please create a recall for this badly handled recall 9c2. My sante fe sport ran beautifully before this recall messed up my SUV. Now I have found if I let it idle for five minutes in the morning and accelerate slowly until it changes gears, most mornings it will run well, but if I crank it and pull into the street on a cold start it does the sputtering help us Hyundai owners.

Brought my 2017 Hyundai Santa Fe sport into the dealer on July 25, 2026 for the ecu and theta ii software update (Hyundai service campaign 9c2). Before the recall service my car drove perfectly with no issues. After the recall service my car is extremely jerky when shifting at low speeds and has long delays when trying to accelerate. This problem is particularly apparent on cold start, and less so once the vehicle has been driving. The issue is not as noticeable if the vehicle has been driven, is turned off, and then turned on again before fully cooled down. The jerky shifting has been getting worse over the past month. Vehicle was taken back to the dealer that conducted the software update on August 26, 2026 and they charged me for throttle body cleaning and efi service which they performed for carbon build up as they cited this as the cause for the issues. The issue was not resolved from this service despite the dealers claims and the vehicle still has the same jerky shifting and delayed acceleration on cold start. There are no warning messages. Issue is becoming more widely documented among users after this particular service campaign so it is not an individual isolated problem.

After a recall repair (campaign 9c2) was performed on my vehicle, it developed a hesitation and lack of acceleration issue that did not exist before the repair. The vehicle exhibits rough or delayed gear shifting, a noticeable lack of power/acceleration, and behavior that feels like the engine is not receiving adequate fuel. This occurs both during cold start and after the vehicle has been driven and is fully warm.

Complete unmitigated loss of acceleration and power while traveling at highway speeds, creating an immediate life-threatening road hazard. Following a warranty engine replacement and mandatory dealer software flash at clay cooley Hyundai (sherman, TX), the vehicle began experiencing powertrain communication issues. While operating the vehicle at 65 mph on the highway, the vehicle completely failed to accelerate and lost propulsion power, nearly resulting in a catastrophic rear-end collision with an oncoming 18-wheeler semi-truck. Dealership diagnostics claim "no trouble codes present," but live data telemetry confirms the high-pressure fuel pump (hpfp) is actively commanding and delivering a dangerous 1,600 psi to the fuel rail at hot idle. This abnormal fuel delivery is paired with a severe powertrain stutter in 3rd gear. Service personnel at multiple locations confirm a widespread, high volume of transmission failures and severe drivability issues specifically tied to this recent Hyundai software update. Corporate has denied repair coverage. The vehicle remains an active highway safety hazard and is completely undrivable.

On July 4, 2026, I was driving 2. 5 hours from home. My car stopped after about an hour of travel. The car shook and the check engine light came on as the car shut down. There were no warning lights on in my vehicle. I have oil change records. My car had burned through all the oil in an hour. This is not a new problem with this model Hyundai. Every group I went to discuss the problem online all had customers who reported their vehicles suddenly started burning oil quickly which resulted in damaged motor with no warning lights in the dashboard. I had to have my car towed from out of town to the dealership. The dealership that said I had extended warranty on parts of the motor. However upon checking the motor, they said it wasn't covered. I filled out a claims report with Hyundai motors who looked into the problem and also said it's not covered under warranty. This is a known issue of Hyundai with a failure to warn of low oil in the car's warning center. This is a fault of Hyundai. I've taken good care of my car and just paid $1000 for new tires on July 2, 2026 before my trip. The dealership quoted me a price of $3500 to replace the motor with a used one. It would also require 16 hours of labor which I believe is $200 an hour. I believe they should replace the motor due to faulty systems. My car has 107,000 miles on it, but whenever I've gone to have it checked out, everything checked out fine even at the dealership. Also, this is a known issue that Hyundai is refusing to address with their customers.

Hyundai performed recall #9c2, on 7/2/26. Since that time, the engine has a full time miss. When it is cold, it will hesitate, kick and buck. Hyundai is aware of this. Their solution is to warm the car for 3 to 5 minuets before moving. What happens if there is an emergency and you can't wait? possible accident with injuries trying to pull into, or cross traffic! I have filed a case with Hyundai, and they just update that they are aware and working on a solution with no expected date for the software fix. This is a serious problem, and they need to fix soon! also, when an engine runs like this, over a period of time it will destroy the catalytic converter. Who's going to pay for that??.

After the update earlier this summer for an emissions issue, my car, a 2017 hyundi Santa Fe sport, has not run right. When it is cold, the first trip on the day, it hesitates and sputters to an extent that it is not safe on the nearest highway where the speed limit is 35. We have been compensating by driving slowly around the neighborhood for a few minutes, and then it's fine. It has been happening since the update of service campaign 9c2, the "theta ii emissions logic improvement" recall. The local Hyundai dealer has been unable to provide a fix. We just picked it back up today, 8/21/26, after deciding against their latest idea, a fuel injector treatment for $200. Based on other examples I've read with similar or identical issues after the recall software update, I have concluded this is a safety issue that Hyundai must resolve.

My 2017 Hyundai Santa Fe was brought to a local Hyundai dealership for routine maintenance on July 1, 2026. The 9c2 software update was installed, without my knowledge or consent, during this service. Immediately after getting my car back, I noticed a problem starting the car (though no warning lights or alerts populated). The car seems to stall and then jerk during the first few minutes of driving, particularly after a cold start (car has been sitting for a few hours before starting). This has been a known issue by Hyundai for several months, yet this update continues to be installed. There is currently no fix, and Hyundai simply suggests letting the car "warm up" for 3-5 minutes before ever driving it. I have reported this to Hyundai corporate and have no other resolutions or timeline on a fix. Many other individuals are affected. This is particularly dangerous due to drivers not always having the ability to wait 3-5 minutes to let their car warm up, and the car is quite difficult to control with all the initial jerking and stalling. I live in a residential neighborhood and continue to be nervous about lack of control over the car when leaving my home. I firmly believe Hyundai should be held responsible for fixing this issue urgently.

Service campaigh 9c2 following completion of service campaign 9c2 (theta ii emissions improvement), certain vehicles may exhibit a brief hesitation or rough shifting condition during cold start operation. My 2017 Hyundai Santa Fe sport has severe loss of power and rough jerky transmission after the update. This condition will definately cause unsafe driving and vehicle engine and transmission damage. Hyundai corporate and local dealerships indicate no remedy for this situation. Dealer also indicated that Hyundai corporate may not release a new software update to fix the issue. This is unacceptable.

We are driving on the highway and the engine just stop working but all lights are still working. I am trying to put gas but it seemed that the engine completely shuts off dangerously without warning. This put my family at risk because there were a lot of big trucks beside us. Theta ii 2. 0l turbo engine just stalled I believe this has been around . Can you please help us.

On June 10, 2024 at 107,129 miles hertrich Hyundai dealership of new castle inspected my vehicle and submitted a request to Hyundai for engine replacement under the recall settlement of the theta ii engine settlement. Hyundai denied the request because of the rebuilt title, even though the rebuilt title resulted only from prior roof damage unrelated to the engine, powertrain, or recall issue. After continuing to seek assistance from Hyundai, my engine ultimately seized and suddenly stopped working on may 10, 2026, while driving on the highway with my two children. The vehicle lost power and stopped in traffic, creating a dangerous situation and causing my children extreme fear and distress. Had Hyundai honored the theta ii engine settlement when I first requested assistance, this failure could have been prevented. I request that Hyundai honor the theta ii engine settlement and replace my defective engine at no cost to avoid any future problems. My Hyundai Santa Fe is covered under the theta ii engine settlement. For over three years, I repeatedly contacted Hyundai after experiencing symptoms consistent with the known theta ii engine defect. Hyundai failed to provide meaningful assistance, did not properly process my requests, and denied coverage solely because of the vehicle’s rebuilt title.

We have been involved with an oil consumption problem since 2025 maybe earlier. No leaks just an over use of oil. I have had to fill it myself or take it to the dealer. They did testing and di some kind of cleaning that took 8 hours. We still have the problem and while driving the whole car shut down. No power in the middle of a highway. This has now happened twice and the first time we had to call aaa for help. It showed an engine sign and we checked the code. First it was an small air leak but they didn't find anything. It came up again, same message so we replaced the gas cap, but the oil was still disappearing and the car had shut down again. I spoke with the Hyundai corporation and they said to do the combustion cleaning again. So we set it up but found out that we had to pay for it so we declined. They refused to do anything about the car. We later found there were other cars made by the same company with the same problem. I did some research and they have had an oil consumption problem for quite a while. Now the catalytic converter is showing up as having problems. Well that's where the oil goes and can shut down the car due to airflow. They never disclosed it to us face to face, we had to find out about it after the the warranty was up. That was very dangerous to have stopped on a highway.

After a recall repair (campaign 9c2) was performed on my vehicle, it developed a hesitation and lack of acceleration issue that did not exist before the repair. The vehicle exhibits rough or delayed gear shifting, a noticeable lack of power/acceleration, and behavior that feels like the engine is not receiving adequate fuel. This occurs both during cold start and after the vehicle has been driven and is fully warm. I returned the vehicle to the dealership (wallace Hyundai), where the service advisor personally test drove the car with me and confirmed he could feel the hesitation firsthand. Despite this, the dealership stated no issue was found and advised warming the car up for 1-3 minutes before driving as a workaround. I tested this exact recommendation, and the issue returned even after the vehicle was fully warmed and had already been driven. Hyundai motor America's national consumer affairs department has stated this is "under review" but has also described the hesitation as "normal" cold-start behavior related to catalyst warm-up. This does not match what I am experiencing, since the issue also occurs when the vehicle is already warm, and their own dealership's advisor confirmed the problem exists. I have also noticed a decrease in fuel efficiency (mpg) since the software update associated with this recall. This issue directly affects the safe operation of the vehicle — specifically the ability to accelerate reliably, including in situations like merging onto highways or pulling into traffic, where a lack of power could result in a collision. I do not consider the vehicle safe to drive in its current condition.

Immediately following the mandatory Hyundai servie campaign update 9c2-ecu theta 11my vehicle began exhibiting severe hesitation, very rough idling, jerking at slow speeds and when gear changes, difficulty going up inclines and almost feel at times as though it is about to lose power which poses life threatening situations especially when turning into traffic. I have reported it to the dealers who never once test drove the vehicle but said to me that they did and could find no problem, however they did make me pay for repairs which never fixed the problem. I returned three times with the same issue. They recommended a fuel induction service and a auto trans service. Spark plug change. Igniton coils change. Nothing worked!.

After having the service campaign 9c2 ecu software update for theta ii emissions improvement, TSB 26-01-013h-2 done, my vehicle started having driveablity issues. On a normal, cold start the engine's rpms go up really high, so I take my foot of the gas and the revs drop, almost stalling the car, and then the car bucks. I put my foot back on the gas pedal, and the engine revs really high again and takes off. If I try to drive normally, the car bucks and runs rough. My car also revs a lot higher during highway driving, than it did before the update. All of this is also causing terrible gas mileage. My car did nothing like this until I had the 9c2 update.

In June 2026 I took my vehicle to Hyundai for a recall to the ecm module. After that my vehicle would lose power and hesitate to shift gears, and overall does not feel safe. Took vehicle back to dealer and they have told me that I have to wait for them to issue a recall fix for this now .

My 2017 Hyundai Santa Fe sport has never had any issues until last Friday when I took my car to the dealership for regular maintenance (oil change, tire rotation) as I always do. They also performed a software update for recall campaign 9c2. Every day since, when first starting the car after it’s been resting for a while, I’ve experienced a jerky transmission and rough shifting for a first couple minutes of driving. Hyundai has acknowledged they are aware of this issue related to the campaign and the dealership said they’ve had many customers complaining of the same problem following the recall update. However, Hyundai has offered no resolution, other than recommending the car warm up for 13 minutes after starting. Hyundai needs to correct the issue they caused, as my car was perfectly fine before it was serviced and now it’s not performing properly.

I own a 2017 Hyundai Santa Fe sport 2. 4l (VIN: [xxx]). On xxx, my vehicle received campaign 9c2 (ecu software update for theta ii emissions improvement). Shortly after this update, I began experiencing a drivability issue that did not exist beforehand. Description of the issue: the problem occurs only after the vehicle has been sitting long enough for the engine to become completely cold, typically overnight. During approximately the first 1/4 mile of driving, the vehicle intermittently jumps, surges, or lurches while accelerating normally. Once the engine warms up, the symptom completely disappears and the vehicle drives normally for the remainder of the trip. There are no warning lights, no check engine light, and no diagnostic messages. The Hyundai dealer has had the vehicle for nearly a week but has been unable to reproduce the concern. Because the issue only occurs during the initial cold start and first portion of the drive, I am concerned that it may not have been tested under the same conditions in which I consistently experience the problem. I am not claiming that campaign 9c2 caused the issue, but the timing is notable because the symptom began only after the ecu update was performed. I am requesting Hyundai's assistance in determining whether: - the ecu update was installed correctly, - any required adaptation or relearn procedure is incomplete, - there are any related technical service bulletins or software updates, or - additional diagnostics should be performed during a true cold-start drive with live data recording. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Hyundai campaign 9c2 recall update: took my vehicle in to have the Hyundai campaign 9c2 recall update performed on the vehicle on June 9th, 2026. Since the update the vehicle is hesitant/jerky upon first drive of the day or anytime it sits more than a few hours. Occasionally it will do this while I am driving. I feel it is a saftey risk because this could cause my vehicle to abruptly hesitate without braking and cause someone to hit me, or worsetransmission to fail while at highway speeds. I took it back to the dealer that performed the required update around June 23rd 2026 and informed them of the problem caused by the 9c2 campaign update. I got the we don't know anything about it causing problems runaround. Even though it has been documented that dealers were notified of this problem. They then wanted to charge me a $100 diagnostic fee to see if it might be something else, I declined that because I know it is from this update. My vehicle ran perfectly fine and smooth before this update was applied and no cel lights are on. I did this update because it was required to be done by Hyundai. When I started researching why my vehicle was hesitant/jerky after the update is when I found that anyone that did this update is having these same issues, and it has been happening for a while now and Hyundai corporation has done nothing to correct this problem other than tell us to sit for at least 3 minutes or more before driving it. That does not help when it does it even after driving for a bit and possibly creating transmission problems.

The contact owns a 2017 Hyundai Santa Fe. The contact stated that after an unknown emission recall was performed on the vehicle, the vehicle started sputtering at start-up and then while driving. There was no warning light illuminated. The dealer was notified of the failure and informed the contact that it was a known failure after the emission recall repair. The contact was informed that the manufacturer was working on a fix for the issue. Additionally, the contact was advised that the recall repair was optional, but the contact had opted to have the vehicle repaired under the recall. The manufacturer was contacted several times, but no assistance was provided. The failure mileage was approximately 78,000.

-the primary mechanical failure is a burned exhaust valve in cylinder 2, which has resulted in 0 psi compression and a persistent engine misfire. This severe top-end valve degradation occurred as a direct consequential result of a chronic, underlying defect in the engine's internal oil-delivery and consumption systems. The vehicle is currently fully assembled, intact, and available for immediate inspection upon request at brown-daub Hyundai. -the vehicle suffered a sudden, severe loss of motive power while operating in traffic due to the cylinder drop, triggering a sudden transition into a dangerous operating state. The extreme oil consumption rate (burning 5 to 6 quarts of motor oil every 3,000 miles) created an ongoing, severe risk of sudden highway stalling, catastrophic moving component seizure, and potential engine bay fire due to extreme internal operating friction and chronic oil starvation. -failure has been confirmed by two independent automotive facilities: independent confirmation: on xxx, [xxx]’s service center performed a diagnostic scan and an engine compression test, formally documenting diagnostic trouble code p030200 (cylinder 2 misfire) and verifying 0 psi compression in cylinder 2. Dealership confirmation: on xxx, the service manager at brown-daub Hyundai executed a formal electronic and mechanical inspection under repair order #xxx, duplicating the failure and logging active trouble codes p0301, p0302, and p0128. -symptoms first appeared progressively through an accelerating, severe oil consumption defect, which was documented during multiple routine maintenance: xxx oil consumption (115,865 mi): xxx (119,601 mi) no external leaks: xxx (125,502 mi) excessive oil consumption:xxx (135,116 mi) excessive oil consumption:xxx (133,022 mi) p0420 cat code: xxx (approx. 137,000 mi)engine rough-riding, shaking, & violent misfires began, preceding the mechanical breakdown information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Air compressor and compression failed engine diagnostic test. Vehicle had high oil and gas consumption.

On may 26. 2026, southern states Hyundai performed mandated service campaign 9c2 (theta ii emissions improvement). The software immediately caused drivability degradation and a catalytic converter failure, mirroring the defects Hyundai acknowledged to the NHTSA on may 18, 2026. Corporate customer care is using an unrelated oil consumption testing protocol to deflect liability and charge me $1,400 for the testing and/or $4002 for the catalytic converter out of pocket for damage caused by their own recall software. This hesitation is a severe safety risk when accelerating into traffic.

Hi, my name is [xxx], I bought used hyndai santafe sport 2017 from dealership in 2020. It had around 47,000 miles on it, intitially it was running fine but after driving 2 years I discovered that engine is burning oil and after the oil change right after 1000 miles I had to add a quart of oil and it was like every two weeks. I had many srevices from dealership and other auto mechanic stores but it didn't improved. I had no choice but to keep driving the card on xxx th the engine crashed with out any sign on dashboard. There was slight noise and it increase by the way car was parked on the side road from highway. The car was towed to my local mechanic and confirmed that engine is crashed. After I had to towed to dealership and I am still waiting for their response. Now we have put 43,000 miles in 6 years (91,000) total mileage. I had bought the waranty from dealership by $ 2500 which expired in 2025 currently no warranty. My question here is that the car is still under 100,000 and engine failed. What if the dealership refuse to replace the engine. What are my leagal rights. Thanks [xxx] [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The 9c2 campaign software update introduced dangerous vehicle hesitation and unpredictable gear changes in active traffic, presenting and immediate crash hazard.

I was told my top side of my engine failed, and they only cover bottom side engine failure. As well as pieces was missing. When I looked at the video it showed that my screws has fell off vs removed.

After the recent "important service campaign" involving the theta ii emissions logic improvement my vehicle no longer safety shifts into the lower gears. It will not shift into gear. I am unable to safely get up to a normal speed and the engine and vehicle start shaking. This is isolated to the initial start of the vehicle and any low speed driving after. The issue is resolved after restarting the car, suggesting it is a software issue. This issue immediately began after the ecu update for the theta ii emissions logic improvement on 5/12/2026.
