2017 Hyundai Santa Fe: stuck in gear or won't shift

Filed Nov 2, 2026 · Engine · NV

On October 14, the vehicle experienced a sudden and catastrophic loss of motive power ("limp mode") while driving at highway speeds, creating an immediate and severe risk of a high-speed rear-end collision. Notably, no Check Engine Light or dashboard warning illuminated prior to or during this sudden deceleration to warn of the failure. On October 16, the vehicle was transferred to an authorized manufacturer dealership (ABC Hyundai in Las Vegas, Dealer Code NV031), where it is currently located and available for inspection. The vehicle has now been in the dealership's custody for 17 consecutive days. Despite telematics data proving the vehicle is being actively started and driven around the dealership lot across multiple shifts, the service department has refused to formally document the diagnostic trouble codes (DTCs) or submit the mandatory engine failure diagnostic paperwork to the manufacturer. The manufacturer's corporate customer care department confirmed on day 17 that the dealership has submitted zero diagnostic data to them regarding this failure. Furthermore, the vehicle had three open safety recalls when surrendered. Records indicate the dealership has performed two of these recall repairs during this 17-day hold without providing any notification, status updates, or documentation to me. Yet, they have deliberately left the most critical mandate—an "URGENT: FIRE RISK WHEN PARKED" safety recall (the federal safety agency Recall 22V056000)—unrepaired. The dealership is actively holding, starting, and driving the vehicle without mitigating this urgent fire risk, while simultaneously refusing to process the engine failure diagnostics or provide a safe alternative vehicle. The dealer's deliberate refusal to process the catastrophic engine failure while selectively performing other recall work in secret presents an ongoing safety hazard and a gross lack of transparency.

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.

Known as an issue with Hyundai, but unresponsive to correct because no diagnostic code is sent. Transmission will shift extremely hard from 1st to 2nd gear randomly. In keeping track of the mileage, this appears to happen every 200 miles or so. Also, it faild to upshift correctly, making the entire car shudder. Also, at times it will not go into reverse gear. On one occasion, after finally doing so, it slammed so hard into reverse I almost collided with the car behind me.

The vehicle is in limp mode and is displaying a flashing check engine light with a P1326 powertrain code. The vehicle in question is a 2017 Hyundai Santa Fe Sport equipped with a Theta II 2.4L GDI engine at 118,000 miles. Per the service campaign T3G, listed on the federal safety agency website, this vehicle is covered under warranty repair since it is a Theta II engine vehicle that is displaying an active P1326 power train code. The vehicle is under he 10 Year/120,000 miles limitations of the extended warranty. The dealer just submitted to us a quote to repair the vehicle and is stating that none of the repairs listed are covered under warranty. This includes a quote to replace the engine knock sensor, which is a warranty item under the T3G service campaign’s extended warranty.

Engine went into limp mode and a knocking sound was heard. Had car inspected and oil changed but no improvements occurred. Took car to dealership and it failed engine test. Hyundai will not cover replacement under open extended warranty.

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.

2107 Santa fe ultimate engine went to limp mode. I have 92k miles. The Vin shows no recalls. The warranty says 1st buyer. I am 2nd buyer, bought at 33k miles. I need help!!! There is no reason other than defect that my engine should have gone out! I've read plenty of things. Excessive oil consumption, rod bearing wear, crankshaft... I need Hyundai to replace my engine.

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.

The engine seized. Driving at 55 mph on a 4 lane highway outside of city limits, the vehicle went into limp mode. Luckily, it was later in the evening with less traffic and I was fortunate enough to be able to turn into a left turn lane and coast into an office building parking lot. There was no shoulder available if I had been in the right lane and somewhat of a rural area. There were no sensors that alerted me prior to this happening. But, when it did happen the dash board lit up like a Christmas tree! It was 6:30 pm, I coasted into a parking spot in the lot and turned the car off. It would not start and I contacted a tow service. I had it towed to an automotive shop near my home. They confirmed the next morning, that there was no oil on the dip stick and the engine seized. They alerted me to the fact that this has become a common problem with this Hyundai engine. I then had the vehicle towed the Hyundai dealership where we purchased the vehicle. We are the original owner. The vehicle is sitting at Rosen Hyundai in Algonquin, IL and should be available for inspection. Monica at the dealership called me after the inspection and confirmed that this is a common issue with this vehicle. She at first used the word recall...and when I asked if there was a recall, she said not a recall, but Hyundai has issued a BULLETIN about this problem. At first, she stated that my maintenance records were in order and being the original owner I qualified to file a claim with Hyundai for engine replacement. 3 days later, she called and stated that Hyundai needed more proof of maintenance than what they could pull off Carfax or my claim was going to be denied. She sent me a picture of the engine and stated that the valves show neglect. I replied of course they do....the engine seized! There was never ever any low oil warning light, check engine or or any warning lights what so ever prior to the event! Hyundai admitted that there is no low oil sensor warning.

The engine has an oil consumption problem. In early April, the oil crankcase was empty between oil changes. I change the oil religiously every 5k miles. In early April, the engine had zero oil and examination showed no leaks. The key safety issue is that no engine warning lights came on. The only reason I discovered the issue was because I noticed it was not running properly and took it to my local Goodyear Service Center who confirmed. The engine could have very easily seized up while I or a family member was driving putting us in real danger of an accident. The issue has been confirmed by the dealer - they are WELL aware of this engine oil consumption issue. One Hyundai dealer inspected the car and tried to tell I had two leaks - valve cover and oil pan gaskets. Both my Goodyear Service Center and a SECOND Hyundai dealer confirmed I do not have leaks (and I pics to prove it). The second Hyundai dealer acknowledged the oil consumption issue and told me to bring the vehicle back if it does it again. They want to charge me $700 for a "compression chamber cleaning" that works 20% of the time! No warning lights - nothing. I only found out because of the way the car was running. It would go into limp mode and not accelerate. That's how I knew something was wrong. There is a Facebook group for this issue and multiple class action law suits. Hyundai refuses to accept responsibility for this engine defect. I asked the service manager at the dealership and he said Hyundai has not addressed this issue EVEN IN NEW CARS. They ignore it because the only remedy is a new engine and Hyundai doesn't want to pay for it. Dealers don't fight for consumers because Hyundai pays dealers a much lower rate to replace the engine then for other warranty work so dealers don't want to be bothered. Meanwhile, consumers are on the hook for an engine defect that Hyundai should fix. This is a crime and a rip-off.

On [XXX], I was driving southbound on the highway near Elizabeth City, NC when all of a sudden, my vehicle decelerated from 65 mph to 20 mph (limp mode) with no warning except for the sudden onset of a knocking noise in the engine compartment and the check engine light coming on immediately before entering limp mode. I was in the passing lane and thankfully was able to safely make it to the shoulder of the road. I had the vehicle towed to an independent engine and transmission shop where I was informed that the timing chain had caused severe damage to the engine, including metal shavings in the fluids. I had just had an oil change 3 days prior and am the second owner of the vehicle. It only has approximately 78,500 miles on it and I have only owned it for three months. I have insured that all maintenance was up to date and verified with the dealer that it had been maintained per the maintenance schedule prior to me purchasing it. The engine seems to be a constant and known problem for 2017 Hyundai Santa Fe’s with the 3.3L engines, and it truly needs to be addressed before someone is seriously injured or, worse yet, killed from not being able to safely make it to the shoulder of a road.
