2017 HYUNDAI SANTA FE Complaints

My car had a thrown connecting rod-the problem described under TSB22-EM-006H-2 (TXXM/6G) which extends engine warranty to 150k miles/15 years for this exact issue my vin is listed my mileage is 113k and KSDS was completed (or I am exempt) please submit prior approval under the extended warranty for engine replacement. Hyundai is refusing to repair my car.

This modle has a serious oil consumption caused by a manufacturerer design issure with the engine. As time goes by the oil cosumption get wores potentially seizing the engine while driving. I have to constantly fill with oil. This is a major safety concern with many hyundai vehicles.

Twice my car's gear shifter went from Drive to the right hand side of the gear box. 90% or more of the power cut out immediately creating a massive safety issue. In both instances, i was pulling into traffic after making complete stops at stop signs. The first time, i turned left, the second time I turned right. The shift was untouched by me as it is not a stick shift car. Hyundai charged me close to $400 for the privledge of telling me that I or something bumped the shifter to the right. Also they claim that the shifter is designed to go into low gear if it does go to the right. a low gear should provide more power not cut it out. They refuse to fix the issue, but wanted me to bring it in so they could duplicate a problem that has occurred twice in four months.

Car stopped running 4 months ago and had it towed to the shop and they did a Knock sensor update and sent us back with it. 4 months later check engine light comes on and take it in and they recommend a new engine and this car has a class action and they’re saying we don’t qualify. They’re saying it’s the piston rings. The car burns oil like crazy. Over 5 quarts in 2,500 miles consistently and the oil light never comes on. I have 2 kids that ride in this car for it to just die or for the engine to start fire is a risk I am not willing to take.

Excessive oil consumption from metal shaving left in engine during production. causes accelerated engine wear and failure. Rod bearing failure. piston ring failure, high chance of fire in engine compartment.

back up camera operates very erratically. some times it works properly, some of the time it is very slow to engage. other times it comes on after i have completed my rearward movement, and some times it comes on after shifting into drive. then there are times t never comes on. i spoke to a dealer tech and was told there are a lot of them like that. if i wanted to spend about $900, they might be able to fix it. this has been going on for a couple of years.

Excessive oil consumption leading to p420 codes every 2000 miles. vehicle is consuming a half a quart of oil every 100 miles. could cause engine to seize while driving.

Was driving on [XXX] (approximately 130 miles from home), when a loud clunking and metal on metal sound was heard, the causing power loss, slowing of vehicle and necessitated immediate pulling over to the side of the road. The was a catastrophic internal engine failure which caused the spark plugs to blow out. There were no warnings. The car was just inspected and had an oil change earlier in the month. The vehicle suffered sudden power loss and violent metal-on-metal destruction while transporting my child on [XXX] (130 miles from home). Certified diagnostics from Kennett Square Quick Lane Auto confirm: "Multiple spark plugs forcibly ejected due to severe internal engine damage – full replacement required". Quick Lane said they would not be able to replace the Engine. so the Vehicle was towed to Reliable Car Connection (West Chester, PA). I had tried to make an appointment at Piazza Hyundai, but the did not have appointments until Mid August. Result: Stranded overnight requiring hotel and towing/tolls at personal expense (receipts available). This traumatic event directly stems from Hyundai’s acknowledged Theta II defects. Hyundai’s Documented Failures: Recall Compliance: Recall 996 (Piazza Hyundai, 4/12/24) Recall 953 (1/31/19) Recall 163 (7/18/17) Maintenance: All services performed per Hyundai schedules (records available). Unresolved Defects: This failure matches: Recall 20VH4 (Lifetime Warranty Extension) Recall 20VH5 TSB 20-01-033H Current Status: Vehicle at Reliable Car Connection (West Chester, PA) after Piazza Hyundai’s unacceptable 6-week delay. INOPERABLE & UNSAFE – Cannot transport children. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated while driving 40 MPH, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The check engine warning light was illuminated. The contact used a personal handheld scanner to scan the vehicle and retrieved DTC: P1326 which indicated a failure with the Knock Sensor Detection System (KSDS). The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 17V578000 (ENGINE AND ENGINE COOLING); however, the VIN was not included. The manufacturer was not informed of the failure. The failure mileage was approximately 80,000.

The turbocharger failed on my 2017 Hyundai Santa Fe Sport 2.0T. It is still on the vehicle and available for inspection upon request. The turbo failure caused a severe loss of engine power, making acceleration dangerously slow and unpredictable, especially when merging onto highways or passing vehicles. This sudden reduction in power could have caused a rear-end collision or made it impossible to avoid faster-moving traffic. Yes. The failure was confirmed by two independent service centers: Mavis Tires and Brakes, and Tires and Trust in Pensacola, FL. Both observed loss of turbo boost and excessive oil consumption consistent with turbocharger failure. Yes. The vehicle was also inspected by Allen Turner Hyundai in Pensacola, FL. They did not detect the failure during their inspection, but the issue persisted and was documented by the other two shops. The check engine light came on around 118,000–119,000 miles. After that, the turbocharger lost significant power, making the vehicle unable to accelerate normally. At the same time, the engine began consuming oil at an abnormally high rate, requiring frequent top-offs between oil changes. This suggests internal oil seal failure in the turbo or related component issues. These symptoms are consistent with failed turbocharger bearings or seals, oil starvation, or blocked oil lines causing overheating and damage. Such failures can release oil and metal debris into the intake and exhaust systems, risking further engine damage or even fire. Hyundai previously issued a software update (KSDS) to detect early bearing wear in these engines, which my vehicle received in 2019 (Service Campaign 953). Despite this, the turbo failure still occurred, suggesting the underlying design or manufacturing issue may not have been fully resolved. I am requesting that NHTSA investigate this pattern of failures, given the safety risks of sudden power loss and potential fire hazard from oil leaks.
