2017 Hyundai Santa Fe

This vehicle has experienced numerous serious failures, including two engine replacements, a transmission replacement, and persistent safety system malfunctions. The Downhill Brake Control (DBC) system remains stuck in the "on" position, and the traction control warning light stays illuminated. These issues directly compromise vehicle safety and stability, particularly on hilly or wet roads. Despite extensive service at Arapahoe Hyundai in Centennial, CO, these problems continue to return. The vehicle has been in the shop multiple times and was most recently in service for nearly 30 days. My wife was stranded at the dealership today due to the same unresolved safety system failure. Dealer communication has been poor, and repairs are often incomplete, requiring immediate return visits. The repeated failure of safety-critical systems, combined with the inability to resolve the issues long-term, presents a significant safety concern for both my family and others on the road. I am requesting NHTSA to investigate whether this is part of a broader defect pattern affecting 2017 Hyundai Santa Fe models and if a recall is warranted.

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)

I bought this vehicle at Enterprise car sales back in [XXX] and it's been having issues for a while now recall after recall I bought this vehicle at 7745 Indiana avenue Riverside California 92504 I actually bought this vehicle without realizing that this car had a recall prior to buying it off the lot therefore in California law this company should have not sold the vehicle with a recall as Hyundai has warned me about this as he advised they cannot sell a vehicle with a recall on it. When I had to Google search my recall as I have not received a letter Enterprise car sales gained the letter for the recall prior to my buy and did not mention anything as this recall was sent out on the letter way prior to buying ever since buying this vehicle I have had numerous recalls as to now there is a GDI issue with the engines as I have made many complaints through the financing company Santander consumer USA, Hyundai, Enterprise car sales, and it seems like no one has listened to me on the lemon I have gained as I'm sure it sounds just like a complaining customer. I pay a very high interest rate and very high monthly payments 523 a month is expensive let alone expensive to pay for a vehicle that I constantly have to put in maintenance and now my engine is gone my VIN number somehow is not on regards to the recall but yet my VIN number has been on every recall Hyundai has ever given out when it comes to my vehicle as the GDI 3.3 l should be really considered on regards to a recall as well as the 2.4. I'm not very happy as I would like to have a voice on to what is fair I am sick of this vehicle having issues after issues as I do take care of my vehicles with good maintenance routine all I can ask for is to have someone here my voice and to take action either from Enterprise car sales to Hyundai which I believe Enterprise car sales is more reliable at this point than Hyundai since Hyundai let me be aware of the California law they cannot sell a vehicle with recall.

The vehicle started to stall/drive in limp mode. I took it to the Hyundai dealership, and they quoted me $5000 for repairs. The repair recommendations were as followed: ensure connecting rod bearings are within spec, recommending performing timing job w/replacement of intake camshaft, e-cvvt motor/gear, e-cvvt cover, and other components necessary for repairs. This engine burns/consumes oil and the engine code that shows up in P00100. All of this after I paid it off. Not within warranty anymore either. $22,000 down the drain it seems... called hyundai customer service to see if there was anything that could be done but they said there is nothing they can do and I have to fix it even though it is a manufacturing issue.

Was going down the highway at 65 when my vehicle completely lost the accelerating component. Almost got rear ended so I pulled off. Then made it to work when it happened again. The engine light came on and gave 2 codes. Finally got it towed to the dealership where they have decided it’s either a new timing chain or new engine due to mechanical loss. They discovered there was no oil in the car and they have also found metal shavings in my oil. Now they are telling me I need a whole new engine. I only have 124000 miles on this car. The car was driving perfectly fine the day before and had just been to the dealer and looked over 1,500 miles before and I was told everything was perfect working condition. I am out $4000 on a car I bought a year and a half ago in October 2023.Was told my warranty only lasted a year.

T3G Campaign 2017 Hyundai Santa Fe Sport AWD, 116000 miles. Purchased from a dealer in VA [XXX]. Never would have purchased if engine issues had been disclosed. The letter re:T3G campaign went out to dealers/service managers from Hyundai (of which I have a copy) is dated for October 2019. We never received any information regarding a T3G campaign. We took my car to the dealership on 12/16/24. (Valdese, NC). In 5 hours, they said they ran diagnostics & found the P0302 Misfire code. Without running further tests, they adamantly claimed there was a dead cylinder & the only fix was to replace the engine. Note: Spark plugs were replaced 2 weeks before this visit on Dec 1, 2024. They refused to listen to my concerns about the T3G campaign. Said vehicle didn't have that issue. That they couldn't run the tests because the P1326 code wasn't present (but it was in Sept). They didn't do anything about the current open recalls. They said they didn't have time. Corporate confirmed that my vehicle has had the correct service campaigns completed to qualify for the T3G campaign. I have called corporate twice-No response. We are very upset over the lack of care and solutions. We gave consent for work & nothing was done. The service manager was practically shouting that this car would leave me stranded, it wasn’t safe to drive, & that the only option to fix was to replace the engine/get rid of it. I was basically told it wasn't worth fixing. Putting a new engine in would equal than the car is worth at trade in value. No one can give me a guarantee that a new engine (even brand new from the factory) would not have the same problem that is happening now. Make this right by immediately authorizing an engine replacement for my vehicle to include a loaner vehicle & tow charge cover. I am aware of the class action lawsuit from 2021. Hyundai refuses to issue a recall for this engine issue. Please see attached letter for more information. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on rural side road, two lanes, my check engine light (yellow, steady) came on. I pulled into a safe spot and did a quick survey, checked the owner manual, but could not identify any problem, and continued on my way. The check engine light was still on. About 15 minutes later the car would not accelerate past 25 mph (limp mode?). I was on a two-lane mountain road, speed limit 45 (but most cars were faster), visibility limited by terrain, trees, etc. Again, there was little traffic around me and I found a safe place to pull over. in neutral the engine revved normally. I turned the ignition off, checked oil level, (normal), turned the engine back on and started driving to find a safe place to pull over and summon help, but the car drove normally. I drove directly to my repair shop and had the codes pulled, (0436, 0021) which indicate a problem with timing. When a qualified tech examined it he recommended taking to the dealer. Unwilling to drive in traffic, I had it towed to the dealership. Their inspection revealed damage to CVVT components and the timing chain, and recommend an (expensive) engine rebuild.

While driving a 1/2 second squeal came from engine compartment. Motor immediately stopped. No power steering or brakes. Vehicle is available for inspection. We were on an interstate We coasted to shoulder. There issue is frequent on Internet forums. A trusted mechanic old us the engine was totally seized. Could be turned manually. No oil in crankcase. At this time only aforementioned mechanic has inspected the vehicle. No warning sounds or performance changes prior to incident. No warning lights or notice warnings were seen prior coincident.
