general problems of the 2017 Hyundai Tucson - part 1

While driving down the highway, the check engine light started to flash. Once the car was turned off and back on again, it shook violently. It was hard to keep it in the lane and I was worried it would cause an accident. It was driven off the highway while constantly shaking. Once it sat off for roughly 30 minutes, it would turn on, but wouldn't turn over and drive. It was towed to a dealership where it was diagnosed, though I was never given anything past a verbal "it stopped compressing". It turns on and over, but makes a grinding noise. It will die and turn off the engine after roughly 45 minutes. This had never happened before. *I've been told a few different things by people who hear about the problem, but I've never received a real diagnosis by the Hyundai dealership it is located at. It has always had a oil consumption problem, adding roughly one quart of oil every 800-1000 miles. It has had oil changes every 5,000 miles. It also had a hard time when cold-started accelerating, but would work fine once heated up. It is available for inspection upon request.

While going down the highway at around 72 mph , my car went into limp mode. I was unable to accelerate, the brake and wheel locked. And then the engine light began flashing. The limp mode , non acceleration, and flashing engine light have happened twice before this instance. The first two times the pulled the p1326 knock sensor code and replaced it. Did the update, and sent me on my way saying it was fine. Now this most recent time (the 3rd time), the engine has failed. A carfax report says my car already had the engine replaced at 52k miles, meaning there’s 1 something internally wrong and 2 it’s still well within mileage warranty for another engine replacement. This car is extremely dangerous as it can literally stop in the middle of the highway. I went from 72 to about 15 mph in seconds, I was unable to get over or accelerate. It was terrifying. Now dealing with Hyundai - they don’t want to take fault.

My name is [xxx]. My husband, [xxx], and I purchased a 2017 Hyundai Tucson (VIN: [xxx]) from a Hyundai dealership in 2023 with 53,920 miles for our daughter to commute to school. The vehicle now has approximately 77,940 miles, and she is still attending school. Since purchasing the vehicle, we have consistently returned to the same Hyundai dealership for regular maintenance, trusting its professionals to keep the vehicle safe and reliable. While driving on the freeway, our daughter suddenly lost engine power. The vehicle slowed down and would no longer accelerate. Thankfully, she managed to exit the highway before it stopped completely. Highway patrol assisted her in moving the vehicle to the roadside. The check engine light and oil-pressure warning light came on, the engine made a pronounced knocking sound, and it would no longer run. We believe these symptoms closely resemble the engine defect described in Hyundai's recall 209 (NHTSA 21v-727), involving connecting-rod-bearing failure in certain 2017 Tucson vehicles. Hyundai motor America denied our request for assistance, stating that our VIN is not included in the recall and that no warranty coverage applies. We respectfully question whether vehicles experiencing the same or substantially similar defect may have been excluded from the recall. We request a technical investigation into why our vehicle was excluded and whether its engine failure is related to the recalled defect. This was a serious safety concern, not merely a repair expense. Our daughter could have suffered a serious accident had she been unable to exit the freeway safely. We are grateful she escaped without injury. We respectfully request that Hyundai reconsider its decision, review the vehicle's maintenance and diagnostic records, and investigate the engine failure. If the failure is related to the recalled defect, we ask Hyundai to cover the cost of engine repair or replacement. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am reporting a suspected safety defect involving my daughter's 2017 Hyundai Tucson, VIN [xxx], with approximately 77,940 miles. The vehicle experienced an engine failure beginning with the illumination of the oil-pressure warning light and check engine light, followed by a pronounced engine knocking noise. The vehicle subsequently could not continue running. The vehicle was inspected by a Hyundai dealership, which diagnosed an engine failure. I am aware of Hyundai safety recall 209 / NHTSA recall 21v-727 involving certain 2017 Hyundai Tucson vehicles equipped with the 2. 0-liter nu gdi engine. Hyundai's recall documentation identifies premature connecting-rod-bearing wear and specifically identifies abnormal engine knocking and illumination of the oil-pressure warning light as symptoms that can precede engine damage and stalling. My daughter's vehicle experienced these same symptoms. Hyundai has informed us that this particular VIN is not included in recall 209 and Hyundai motor America has denied our request for assistance. I am therefore asking NHTSA to review this complaint as a potential safety defect and determine whether there may be additional 2017 Tucson vehicles outside the current recall 209 population experiencing the same or substantially similar engine failure. I am not claiming that the vehicle is definitively covered by recall 209. Rather, I am asking NHTSA to investigate whether the exclusion of this vehicle is appropriate given the similarity between the actual failure symptoms and the defect identified in recall 209. I can provide the dealership's diagnostic documentation, Hyundai motor America's denial, photographs, maintenance records, and other supporting information upon request. Vehicle: 2017 Hyundai Tucson, VIN: [xxx], mileage: approximately 77,940 miles failure: engine knocking, oil-pressure warning light, check engine light, engine failure/stalling related recall: Hyundai recall 209 / NHTSA 21v-727.

Franchise dealer preson Hyundai is actively obstructing a court-ordered settlement tracking test for an engine burning 2. 0 qts internally, forcing a young driver with child to operate an oil starving vehicle at risk of highway engine seizure and fire.

Vehicle is losing a lot of oil. But there is no oil leaking on the ground. Upon looking at the safety recall, it says it might be fire hazardous. I noticed smoke coming from under the hood. Vehicle run rough and also hear sounds.

On July 31, 2026, I purchased a 2017 Hyundai Tucson from drivetime, located at 6400 pensacola boulevard, pensacola, FL 32505. Within approximately nine days of purchase, the vehicle began experiencing serious mechanical problems, raising significant concerns about its safety and roadworthiness. On August 10, 2026, the vehicle suffered a severe loss of acceleration and was unable to exceed approximately 30 mph. This sudden reduction in engine performance created a dangerous situation while driving, particularly when attempting to maintain normal traffic speeds. Following these issues, mechanical inspections revealed water inside the spark plug wells, a severely rusted ignition coil, and a failing catalytic converter. Firestone estimated the catalytic converter repair at approximately $5,000. The presence of water and corrosion raised concerns about possible pre-existing damage and whether the vehicle had been properly inspected before being sold. The vehicle remained in repair-related custody for approximately 29 days. Despite repeated communications with drivetime, the mechanical problems were not satisfactorily resolved. Drivetime representatives informed me that a replacement vehicle had been approved. On September 15, 2026, I returned to the dealership expecting a replacement but was informed that no suitable vehicle was available. I was left without transportation, and the dealership failed to provide a satisfactory resolution. As of October 21, 2026, I remain without a vehicle. I am requesting that NHTSA investigate the sudden loss of engine power, possible electrical or ignition system damage caused by moisture intrusion, and any similar safety complaints involving the 2017 Hyundai Tucson. My primary concern is that these mechanical failures could cause another driver to experience a dangerous loss of power while operating the vehicle, potentially resulting in a serious collision.

Vehicle was operating normally and when arriving at a gas station to refuel the vehicle would not start after turning off. Vehicle was towed to the dealership (larry miller Hyundai albuquerque, and a seized motor was described as the discrepancy. No further maintenance has been performed.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the vehicle was shaking and vibrating abnormally, and the engine was making abnormal sounds. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, and an oil change was performed as associated with NHTSA campaign number: 21v727000 (engine); however, the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 97,000.

While traveling on the highway the car began to lose speed rapidly until coming to a complete stop, no warning lights were present prior.

Failed component: engine assembly / internal powertrain (specifically, a connecting rod bearing failure in cylinder #2 causing severe engine knocking and risk of mechanical seizure). The vehicle is available for inspection, the complete vehicle and affected engine assembly are intact and available for inspection upon request at cma's Hyundai of lexington park: [xxx] safety risk: a rod bearing failure causes violent engine knocking, severe loss of engine power, and eventual engine seizure or stalling while driving. Losing propulsion unexpectedly—especially at highway speeds or in heavy traffic—creates an immediate collision risk for the vehicle occupants and surrounding traffic due to sudden loss of power, power steering, and power brake assistance. The issue was formally diagnosed and confirmed by an authorized Hyundai dealership service department. The technician performed a physical diagnostic evaluation and officially documented a knocking condition resulting from a connecting rod bearing failure in cylinder #2. Symptoms & timeline: initial engine knocking noises first appeared on xxx. The vehicle was previously updated with Hyundai's knock sensor detection system (ksds) product improvement campaign, which is intended to detect excessive vibration from rod bearing wear prior to catastrophic failure. No check engine light illumination occurred or and type of indication from the vehicle there was something wrong other than the knocking noises. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at 65 mph, the vehicle unexpectedly stalled and was unable to exceed 30 mph. The contact pulled the vehicle over to the shoulder of the road, and the vehicle failed to restart. The vehicle was towed to the dealer, where it was diagnosed that the transmission failed and oil contaminated the catalytic converter, causing the catalytic converter to fail and require replacement. The transmission was repaired by the dealer, and the catalytic converter was replaced by an independent repair facility. The contact subsequently observed continued oil loss following the repairs. The vehicle was returned to the dealer, where it was diagnosed that the exhaust manifold headers failed and required replacement. The vehicle was not repaired. The contact requested and received a complete diagnostic report from the dealer. The failure mileage was approximately 90,502.

I am filing a safety complaint regarding my Hyundai vehicle after experiencing a sudden engine failure that appears consistent with known rod bearing and engine defects affecting certain Hyundai engines. While driving, my vehicle began making a knocking noise and shortly thereafter suffered catastrophic engine failure. The engine lost power and became inoperable, requiring the vehicle to be towed. This failure occurred without any prior indication that the engine was about to fail. My concern is that this type of engine failure creates a significant safety hazard because it can occur unexpectedly while driving, potentially causing a loss of power in traffic and increasing the risk of a crash. The dealership inspected the vehicle and engine but did not report excessive sludge buildup. I have provided available maintenance records showing that oil changes were performed during my ownership. Despite this, there appears to be disagreement regarding the cause of the failure. I am aware of reports involving rod bearing and engine failures in similar Hyundai vehicles and believe NHTSA should investigate whether this failure is related to a broader manufacturing or design defect. The cost of replacing the engine is substantial, and consumers may be placed at risk if these failures occur while vehicles are being operated on public roads. I am requesting that NHTSA review this issue and determine whether additional investigation, recalls, or other corrective actions are warranted. Vehicle information: year: 2017 make: Hyundai model: Tucson mileage at failure: approximately 72,000 miles date of failure: [xxx] VIN: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

2017 Hyundai Tucson | VIN: [xxx] | mileage: 75,000 I have owned this vehicle for approximately five years and have experienced severe excessive oil consumption for the past two to three years. The issue was first discovered when the vehicle entered protective mode due to critically low oil levels despite a routine oil change having been performed only a few months prior. I am currently required to add approximately one quart of oil every month to maintain safe operating levels. I visited an authorized Hyundai dealership to have an oil consumption test performed. The dealership informed me that if the test confirmed excessive consumption, I would be required to pay out of pocket for an engine replacement. I declined, as Hyundai motor America has publicly acknowledged this exact defect in the 2017 Tucson through NHTSA recall 21v727000, multiple technical service bulletins, and a class action settlement covering 2014-2021 Tucson vehicles with the nu 2. 0-liter gdi engine. My VIN was found ineligible on the class action settlement website despite the acknowledged defect. Hyundai has admitted this engine suffers from premature bearing wear, excessive oil consumption, and risk of engine failure and fire. I am requesting NHTSA investigate why my VIN falls outside current recall coverage despite presenting identical symptoms to affected vehicles. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The engine (connecting rod bearings in the 2. 0l nu gdi engine) failed. The vehicle entered limp mode with dtc p1326, then died on the road and the engine seized completely (will not turn by hand when attempted; only clicks on starter). It is currently at first Hyundai dealer in [xxx], under repair order #xxxand available for inspection. The vehicle suddenly lost power and died while driving on the road. This created a significant risk of an accident or being stranded in traffic. I was on a busy highway and almost got hit twice. There is also a known fire risk associated with this exact defect (oil leaking onto hot engine components), as stated in recall 209 (NHTSA 21v727). The vehicle was towed to first Hyundai. They have documented the no-start/seized condition on repair order #xxx. A prior independent scanner reading showed p1326 before the code was cleared. The dealer has not performed the full diagnostic inspection (scheduled around June 11). Hyundai corporate (claim #xxx) has been notified but has not responded after multiple escalation emails. The vehicle first went into limp mode ("engine protection mode") with dtc p1326 on the scanner. Shortly after, the engine died completely and would not restart. This occurred after recall 209 (bearing/ksds campaign) was completed on xxx. Additional details: this is a known issue with premature connecting rod bearing wear. The dealer is refusing to provide a loaner/rental upon drop-off, which contradicts TSB 22-01-023h (dealer best practices for p1326 vehicles). The vehicle has been inoperable since 6/4 . . With no resolution. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Car was driving weird consuming lots of oil check engine light flashing took to mechanic where they replaced the spark plugs and ignition coils, cleared light. Issue was resolved for about a month. Rough idling began car begin to shake while driving. Took back to shop was told rod bearring problem. Upon research found out this is a commkon problem among Hyundai vehicles however my vehicle was not apart of the ‘affected batch’. Took to Hyundai and got a diagnostic where it was confirmed that a new engine was needed, for $9000.

Catastrophic engine failures at 57k miles while driving, resulted in engine replacment under recall warranty. Timing chain replacement done at 93k miles. Second engine failure while driving at 107k. Hyundai refuses to fix the engine.

I am submitting a complaint regarding a 2017 Hyundai Tucson ultimate awd equipped with the 1. 6l turbo gamma gdi engine. My vehicle currently has approximately 127,000 miles and has experienced sudden engine knocking consistent with rod bearing failure and/or catastrophic internal engine damage. The vehicle has been properly maintained, including regular oil changes. However, the engine began consuming excessive oil without warning. Upon inspection by an independent repair facility, the engine was found to have extremely low oil levels despite being within the normal oil change interval. After refilling the oil, the engine continued making severe knocking noises, and the repair facility advised that the engine is likely non-repairable and requires replacement. This failure appears materially similar to the rod bearing and engine failure issues already widely documented in Hyundai/kia engine defect investigations and class action settlements involving related gamma and gdi engine platforms. I have learned that Hyundai extended warranties for certain vehicles with similar engine defects up to 15 years/150,000 miles; however, my specific Tucson trim/engine configuration does not appear included despite experiencing the same type of failure. This vehicle has also previously required major drivetrain repairs under warranty, including two transmission replacements and turbocharger replacement. My concern is both financial and safety-related. A sudden engine failure or seizure while driving could create a serious roadway hazard and risk of loss of power in traffic. Additionally, Hyundai dealerships have advised that replacement engines for this vehicle are no longer readily available. I believe Hyundai should further investigate whether the 2017 Tucson 1. 6t gamma gdi engine should be included in existing engine defect warranty extensions and/or recalls.

My hundai tuscon 2017 was making a whurring sound on the highway, at which time my rpm's were not going over 3. As I was looking for places to pull over on the highway, I heard a loud 'pop' and then my engine started smoking and an intense rattling ensued to where I could hear a series of parts drop out of the bottom of my car. My car began smoking and the engine completely stalled just in time for me to make it to the side of the road. I took it to a local shop for repairs and they showed me three holes in my engine.

My 2017 Hyundai Tucson is experiencing dangerous, sudden engine stalling, which are symptoms directly matching service campaign t1b. These critical safety issues surfaced following a total engine replacement in June 2025. Despite the vehicle being within the 12-month/12,000 mile workmanship warranty, the dealership is refusing to honor this coverage or offer goodwill assistance. My claim is based on a documented pattern of physical and technical negligence: - failure to update software: the dealership failed to perform the mandatory ecm/tcm software integration (campaign t1b) during engine swap, which is required to prevent the exact stalling I am now experiencing. - dismissal of warning lights (code p0456): one day after the engine replacement was “completed,” I returned to the dealership because the check engine light illuminated with code p0456. This was dismissed by the service provider without a proper diagnostic resolution, despite being a direct indicator of improper vacuum line reconnection during the engine installation. - mechanical negligence (coolant leak): post-engine swap, the vehicle developed a coolant leak, which was a direct result of improper reassembly. Additional proof of the lack of due diligence during the repair. The lack of follow-through, combined with the dismissal of a life-safety defect and poor physical workmanship, suggests a total failure in the case management process. I am urgently requesting assistance to resolve this hazardous situation.

Knocking noise in motor and metal flakes in the oil. Called local dealership. They report no recalls for this issue.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the engine made a ticking sound. No warning light was illuminated. The vehicle was taken to the dealer and was repaired under NHTSA campaign numbers: 20v543000 (service brakes, hydraulic) and 21v727000 (engine); however, the failure occurred after the recall repairs were performed. The contact stated that while driving at an undisclosed speed, the vehicle stalled and failed to accelerate above 40 mph. Additionally, while depressing the accelerator pedal, there was an extremely loud ticking sound coming from the engine. The check engine warning light was illuminated. The vehicle was taken back to the dealer; however, the vehicle was not yet diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 67,700.

The contact owns a 2017 Hyundai Tucson. The contact stated that while starting the vehicle and driving at an undisclosed speed, there was an abnormally loud grumbling sound coming from the engine. There was no warning light illuminated. The contact stated that the vehicle unexpectedly entered limp mode. There was no warning light illuminated. The vehicle was towed to the dealer but was not diagnosed or repaired. The manufacturer was made aware of the failure and informed the contact that documentation of previous oil changes was required. The contact stated that the manufacturer accused the contact of a lack of maintenance, which was associated with the engine failure. The failure mileage was approximately 98,000.

While driving my vehicle, the engine rpm suddenly revved very high, and the vehicle hesitated to accelerate. A warning messaged appeared stating "transmission too hot stop safely. " I was driving up a hill when this happened. I pulled over and turned the vehicle off for about two minutes. When I restarted the vehicle, the warning message disappeared even though the vehicle would not realistically have cooled down that quickly. The issue concerns me because it could create a dangerous situation in traffic if the vehicle loses power or hesitates to accelerate when pulling into traffic or climbing a hill. The problem has occurred without warning and does not leave and persistent warning lights afterwards. I am very scared to drive this car, especially when I have my child with me. If I need to move out of the way and someone is driving that is not paying attention, there will be an accident because of the hesitation and the non-movement when I accelerate. I am reporting this issue in case it is related to a defect with the transmission system in this vehicle.

On March 10, 2026, my 2017 Hyundai Tucson entered 'limp home mode' while driving, a known safety defect that causes a sudden loss of engine power. Diagnostic testing confirmed error code p1326 (knock sensor detection system - ksds). Despite this vehicle being covered under the theta ii engine class action settlement (recall 209), which provides a 15-year/150,000-mile extended warranty for this specific issue, the dealership (jim ellis Hyundai of atlanta) is refusing to perform the warrantied repair. Instead, the dealership has provided an estimate (#xxx) attempting to charge me $816. 22 for the knock sensor replacement. They are also withholding the full gds diagnostic scan reports and freeze frame data despite multiple written requests. Furthermore, the dealership is threatening to charge daily storage fees while actively denying a mandated safety repair. This refusal to honor the settlement warranty leaves the vehicle in an unsafe, unrepaired condition. This vehicle is a subject of the in Hyundai and kia engine litigation ii settlement. The refusal of the dealership to perform the ksds-related repair (p1326}) is a direct violation of the court-approved settlement terms and a failure to address a documented safety defect. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I keep having to add oil but there is no puddle from a leak on the ground. There is also no smoke coming out of the exhaust. It is using an excessive amount of oil.

The vehicle has a difficult time turning over when cranking, the rpms are sticking and the car periodically shuts off at red lights. Several warning lights pop up when it won't crank and then other warnings when the car just completely shuts off at red lights. I drive the interstate in [xxx] daily for work, so with the engine stalling my safety is at risk every time I drive it. Likewise when it won't crank, my safety is at risk. I had two Hyundai recalls updated in my car in 2022, Hyundai recall 209 which was a connecting rod bearing test and my car passed so they installed the other Hyundai recall 966 which was software update for the knock sensor detection system to alert the driver of future issues. Those issues are now current. The software is detecting a critical failure which is why the car is shutting off - entering limp mode, or the engine is failing. On April 9th through the 11th, 2026 my vehicle was inspected by a Hyundai dealership, where a technician identified a developing engine concern and advised me to continue driving the vehicle. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

This car has major oil consumption that affects the engine and catalytic converter. This can cause engine damage and stalls in driving that affect safety on the roads because the car doesn't accelerate properly. There were no warning signals to indicate this being a problem with the car, especially at purchase. This car will get an oil change and in less than a week, the oil is gone and bone dry.

The contact owns a 2017 Hyundai Tucson. The contact stated that after the vehicle was taken to the dealer for a recall repair, there was a burning odor coming from the vehicle, with white smoke from the tailpipe. Additionally, the check engine warning light was illuminated. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 50,000.

The contact owns a 2017 Hyundai Tucson. The contact stated that the vehicle was consuming an excessive amount of engine oil. There was an abnormal knocking sound coming from the vehicle. There was no warning light illuminated. Due to the failure, the vehicle was towed to a dealer, and the excessive oil consumption was confirmed. The contact was informed that the vehicle was included in NHTSA campaign number: 21v727000 (engine), and the engine was replaced. The vehicle was repaired, and a family member retrieved the vehicle and drove it to the residence without failure. Several days later, the family member started the vehicle, and fuel started pouring out from underneath the vehicle. Due to the failure, the vehicle was towed back to the dealer and was diagnosed the vehicle with an o-ring failure inside the fuel injectors. The dealer repaired the o-ring, and the contact picked up the vehicle from the dealer. Soon after retrieving the vehicle, fuel started pouring out from under the vehicle at start-up. The vehicle was towed back to the dealer and remained with the dealer. The manufacturer was notified of the failure, and a claim was filed. The vehicle was not repaired. The failure mileage was approximately 68,000.

I purchased this car from drive time, and when told about a possible recall on the engine I asked about it. We were told that the issue had been resolved. Not even 10 minutes after driving it off the lot the engine started misfiring, we had done a test drive prior to purchasing this vehicle and nothing had popped up on the dash about any problems. We have been unable to get it looked at. I was not sure if a report should have been filed until now. I am unable to produce photos at this time.

Purchased used via carvana in sept 2025, check engine light came on while driving it home indicating a pre-existing mechanical defect. We submitted the claim through silver rock (carvana's warranty company) and brought to their approved mechanic. The recommended the following repairs, several that were denied by carvana/silverrock: spark plugs, alternator, serpentine belt, fuel injection service, electrical ignition coil. A month later check engine light illuminated again and through further diagnostics the mechanic found that 2 of the faulty spark plugs were an incorrect model/fit for our vehicle and reported that information which resulted in replacement being approved (a month after initial request). Fast forward to January 2026 we experienced the widely reported knocking noise while driving coming from the engine and had it towed. The damage is a thrown rod and damaged bearing, which is consistent with the current oil consumption litigation, requiring engine replacement. Our 2017 Tucson 1. 6 l turbocharge is not included in the recall. Furthermore, carfax report shows last oil change reported was 2023. Carvana confirms an oil change is part of their 150 point inspection before a sale, however unable to provide me with documentation and failed to report a record of the work to carfax. There are many instances of negligence on carvana's part from failure to provide record of maintenance, which is also failure to adhere to their standard policy, and declining recommended service directly from their approved mechanic, knowing that this vehicle could be impacted by the well known defects through Hyundai. We are requesting assistance with engine replacement meeting safety standards and ensuring consumer protection.

Following the knock sensor detection system update, this car has a p1326 code that forces it into limp mode. Occurs during moderate-hard acceleration, e. G. Getting on a highway. The car is limited to ?2000 rpm and ? 45 mph, and rapidly decelerates to that speed if necessary. Acceleration is very limited. This occurs roughly every two weeks, despite having a brand new sensor installed by Hyundai. Hyundai has also allegedly performed cleaning on the sensor and related parts. This has been going on since November, when the recall that installed this update was performed.
