Owner reports
Selected complaints filed with NHTSA by 2008 Hyundai Elantra owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2008 Hyundai Elantra. The contact stated while driving 30 MPH, the vehicle started jerking and stalled. There were no warning lights illuminated. The vehicle was taken to an independent mechanic who diagnosed the vehicle with fuel pump failure. The contact stated that the vehicle stalled intermittently. The vehicle was not repaired. The dealer was not made aware of the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 172,600.
Has not yet been officially diagnosed by a dealer or independent service center, but while turning into a neighborhood at around 15-25 mph the car jerked and the engine suddenly stalled while I was still in the middle of the road. Thankfully I rolled into the neighborhood before an oncoming car made its way over, but it was close. The gas pedal no longer worked, and I had to restart the car. It only drove once more before shutting down and the engine will no longer turn over.
The check engine light came on when I started up the car one morning in early May; ended up getting a new gas cap. 24 hours later, check engine light comes on again when I start up the car. After smoke testing for leaks, got the purge valve replaced. 24 hours later, check engine light comes on again while I'm at a stop light. Waited couple months due to no income during pandemic. Code was the same regarding emissions issues; another smoke test revealed faulty vent canister valve. Got it replaced and drove fine for an hour. Few hours later, the light came back on once again while I'm accelerating after a turn. The mechanic that installed the vcv checked the part as well as the purge valve and noticed neither part were functioning as needed. He stated potential ECU issue or faulty fuel tank pressure sensor with the likelihood of the latter being the most likely cause. …
2008 elentra began experiencing failures to start. Removing the fuel pump access cover and pounding on the fuel pump would usually result in successful starting. This fuel pump was a replacement in 2008 under recall 08V694000 because of intermittent failure to run. We thought it again might be the fuel pump motor. However, when we replaced the fuel pump, we found the problem was a bad motor connector plug that had obviously overheated. If this connector became too hot or started sparking inside the tank, it seems like there May be possibility of fuel ignition.
New 2008 Hyundai Elantra gls, had problems in 1st gear engine would shut off and sometimes it would run very ruff ,sometimes starting the car I would turn the key and it was like the battery was dead had to do it 2 or 3 times before the starter would catch on and start the car. I only drove this car for 12 days before taking it into the dealer for a complete check up also the alarm wasnt working.

My husband did not get hit, but in order to avoid him a car swerved, got rear-ended and pushed into an 18 wheeler on rte 24 in millburn nj. There is a police report because of this.

The service manager also said Hyundai is aware of this problem but are not ordering a recall to have the 2008 fuel pumps changed.

My fiancee and I recently purchased a brand new(had 7 miles on when we got it) 2008 Hyundai Elantra. In about the third week of ownership, we took a road trip out of state. While returning home, on the ny state thruway, the car began to shake and shudder, and lose speed rapidly. The engine light came on and I pulled over to the shoulder. After about half an hour, I tried to drive again and had the same problems. We were towed off of the thruway, then to a Hyundai dealership by hra, where they looked at the vehicle for a morning. The problem was diagnosed as 'bad gas'. We were told to buy a container of dry gas and sent on our way. The car seemed to behave for about 5 days, then the next weekend I ventured out of town again in my still new car. About an hour into my trip, the car started shuddering and shaking on interstate 84. …
My 2008 Elantra se which I bought in May has had two "episodes" of stalling. The first (od 1100 mi) on July 14 occurred on the freeway and began as a slight hesitation that got progressively worse such that we took the next exit and limped home on back roads. The check engine light came on and the car stalled twice before we finally made it home. The next day I was able to drive it to the dealer about 5 miles away. Their diagnosis was a bad oxygen sensor which they didn't have in stock. They said it would be OK to drive the car until the new sensor arrived. It ran fine and 3 days later I took it in to have the sensor replaced. They ran diagnostics again and said the sensor was OK and needn't be replaced. They said maybe it was bad gas or vapor lock and sent me on my way. …
Was driving new Elantra (1100 miles and 12 days of ownership) on highway when vehicle started sputtering and lost power no matter how much gas I fed it. Pulled over and turned off car. Restarted vehicle with difficulty and "check engine" light indicating emissions problem came on. Car seemed fine until 2-3 miles later when same symptoms (lurching, losing power) recurred.. This happened 2 more times, each time I managed to pull off road, turned off car, let it sit and then took multiple attempts at starting before it engaged and ran very rough, with very little power. Intent was to get to a safe place to stop. Car was towed to nearest huyndai dealership (I was 150 miles from home) where they initially diagnosed bad gas. But car ran 175 miles on that tank of gas before problem occurred. Then they diagnosed bad fuel pump and replaced fuel pump. …
The car stalled 6/21/11 at 7 pm on the freeway in 10-20 mile an hour stop and go traffic. The temp outside was mild, I had been on the road for 20 min before hitting traffic, and both air conditioning and radio were on. I was in traffic approx. 10 min. I went to tap the gas pedal and nothing was there. I had to get out (on freeway) and push the car off the road and onto center divide (no call boxes). Two strangers stopped and helped me to side of road. After 5 minutes I was able to start car and drive home. The car stalled again on 7/29/11 in 10-20 MPH stop and go traffic at 5 pm. The temp was mild and I had just filled the car with gas. 15 minutes later on the freeway (stop and go traffic), with air conditioner and radio on, I went to tap the gas pedal and nothing was there. Was in traffic less than 10 min. Again stuck in the middle of the freeway. …
