2015 Hyundai Elantra: engine stalls while driving

Filed Jul 16, 2025 · Engine · UT

Vehicle routinely (3,000-5,000 miles, depending on oil used) maintained by qualified mechanics. Around 129,000 miles the engine began to knock / rattle. Mechanic was unable to determine the cause, but the rattle was only present between 0-40mph and would settle at higher speeds. Mechanic also noted the absence of sludge. Around 133,000 miles the vehicle stalled. The vehicle would start, but would stall again. Mechanic diagnosed timing chain failure and that the vehicle is burning oil. Vehicle has never indicated low oil, but it is now manually checked and burning about a quart of oil per 1,000 miles. Replaced timing chain and vehicle has continued to operate. Around 134,500 miles some power loss during low-speed acceleration and a slight engine rumble at lower speed. Mechanic diagnosed a wrist pin failure on cylinder 2. Vehicle may be inspected upon request. Vehicle stalls create some safety concerns, but have only occurred at low speeds. Vehicle timing chain was diagnosed by two different mechanics. When the vehicle was brought to a Hyundai dealership for a trunk latch recall in May of 2024 at 125,000 miles, no issues were noted. Vehicle has not been inspected by the manufacturer, police, or insurance represenstatives since May of 2024, with no reported issues. No check engine notifications or warnings appeared until the vehicle stalled. Prior to slightly decreased acceleration, the only notable indicator of an issue is the persistent engine rattle (knock, piston slap). The engine rattle began in February of 2025.

For the past 2 years, the car shuts off while driving. There is no warning lights or other warning that it is going to shut off. The steering doesn't lock but the car shuts off. I have to come to a stop and then restart the car. It does restart every time. This seems to happen frequently and then doesn't do it for a few weeks. I have had it looked at by 4 different mechanics, had multiple sensors replaces, replaced coil packs, and the problem still continues. The Hyundai dealer looked at it one time and said they do not know what is wrong.

While operating my 2015 Hyundai ELANTRA, the engine cuts out.. it just stalls out of nowhere without any signs or warnings its about to happen. As well as approximately 50% of the time the engine stalls the power steering also stops working. At this point I have to coast to the side of the road, put it in park, turn the key to the off position and then restart the car when this happens which is quite often. The worst its ever been was 8 times in a 25 minute/28 mile drive. This doesn’t only happen at fast or slow speeds. It’s completely random whether I’m going 15 mph in a school zone 25 to 40 mph through towns or 65 to 70 mph on highways. This is already extremely dangerous to happen. Going 15 to 40 mph but when you’re driving on a highway at 65 or 70 mph and the engine and power steering just stop and cut out, this is severely dangerous. I’ve been in contact with the Hyundai headquarters multiple times and they are not doing a single thing about it so my car has just been sitting for about 5 months now. Please help me hold Hyundai financially responsible for safety recall repairs. This manufacturer safety issue is unacceptable and my car has been very well maintained and has very low miles under 70k miles on a 2015

Car will accelerate and get stuck in a high gear rpm gauge will not work as well You will come to a stop not knowing you are stuck in a high gear car will not downshift. I tried to cross the intersection from a stop and almost got hit because I could barely accelerate. I was stuck in 5th gear. Car will also stall while stuck in in a high gear at a stop I can turn off the vehicle and start it and it will reset the car to normal. It will drive fine for a while. Randomly this will happen. From my research I found this is a common problem with many different model years of Hyundai's . Most people say the solution is a new crankshaft sensor . When I ran a diagnostics There are no error codes for this problem. Many other individuals with this problem have said the same from many different online forums I have read. Other individuals I've said they were also stuck in the high gear at a stop and did not know until they accelerated. Some have been in accidents because of this issue. I would assume Hyundai would be aware of this. If there's not a recall on this, I believe there should be.

About 6 weeks ago, my car engine began to turn off while driving. Warning lights flash on the gauge cluster. The vehicle has limited mobility for 20–30 seconds, then loses all power. This was incredibly dangerous when driving at highway speeds, as the car simply stopped. There were no warning lights or issues before this began happening. I took it to a local mechanic who identified several error messages and replaced the battery, throttle, sensors, and other parts, but the problem persisted. They could not identify the cause but verified the problem. I took the car to the Skagit, WAHyundai dealership, where they determined it was a failure in the oil pump. This exact problem is under an active recall for other Hyundai Elantra model years.

Within three months of purchasing this vehicle, I started having engine light and oil consumption issues. Within the 4 years of owning, they've replaced the catalytic converter twice, many valves, and others. I had to purchase and add multiple quarts of oil to just maintain oil levels. I've had multiple occasions where my vehicle slowed to only up to 55 miles an hour while on the interstate. The vehicle had issues accelerating where an accident almost occurred because pulling into a shopping plaza, the vehicle couldn't drive up a minor hill and almost remained in the intersection. I've had multiple times where I was stuck on the side of the road in different environments, a few of which I was genuinely worried for my safety. This last incident I did not feel safe to drive where I needed to go so I got off the interstate to travel down a local road where the vehicle stalled in the middle of a 5 lane (one direction) busy road. The vehicle has been inspected by the dealership and warranty representatives. The engine and oil lights were the main issues, every time a light came on I reached out to the dealership to get it looked at. I received notice of many engines being recalled and repaired in 2022 yet Hyundai has only put bandaids on my engine.

Engine stalled while going at-speed on major highway; high risk of crash if not restarted in time. Continuous repeating stalls. Hyundai inspected car twice; failed to fix the problem on the first attempt, refused to replace engine alleging that maintenance was negligent due to residue inside motor. Hyundai did not report any residue on the first inspection, and likely did not inspect engine thoroughly when stalling was initially reported to their mechanics. Odd noises from engine present for months prior to stalling.

My vehicle is just over 80k miles and has received regular maintenance services. Inspection available upon request. My engine would rattle during idle, stopped at a light, and sounded as if the RPM were increasing. I would have to turn my car off then back on for it to stop. No engine or warning lights. As this became more frequent, I also noticed a very intense shaking coming from the front passenger side of the vehicle while driving on the highway. The shaking was most intense as the car accelerated from 2k-3k RPM. It felt like I could have lost control. On 11/29/22, my car was towed to a repair shop because the engine would stall when I started my car. After examination they recommended I take it to a Hyundai dealer, determined the engine may need replaced and informed me of other recalls from similar models. When the vehicle was brought to the Hyundai dealer, they stated they could not replicate the issue - the engine would start without stalling - but they also speculated my problem was from a loose cable, and attempted to send my car home with me the same day. It is important to note that the battery cable was examined and was connected prior to bringing it in to the dealer. My car is not under recall so my request was taken lightly, they stated I had no engine issues. I pressed for them to address the rattling of my vehicle, for which they then told me I had a leak in my front left axle. Axle was repaired and car brought home. My car drove for about 212 miles before it started stalling again with multiple attempts to start it. When I was able to successfully turn the engine over, I drove it back to the Hyundai dealer on 1/02/23. They found no codes but determined the crank sensor needed replaced. After replacement, they informed me my vehicle still “acted up” once, so they have held onto the vehicle for the past month, letting it sit and occasionally test driving it. Still no answer to this irregular issue.
