Car lunched from a traveling in traffic 50+ mph to 39 mph and then had to push the pedal to the floor to get it off the highway and on the side during 5 o'clock traffic. Said something about the hybrid battery and went dead. Dealer has had it for 11 days and still can't get it started. Apparently there are THREE batteries in relation to this hybrid and all 3 don't work and never seen this before. Since it's been at the dealer, hyundai has emailed me no less than 3 times that I need to check my lights because my battery is getting low all the while it has been completely dead and they don't even know it. Suffice to say, there was NO WARNING other than a couple of miles prior, my car lunched down to the 39 mph and I lunged on the gas and it picked back up again but it wouldn't do it a 2d time. They obviously still don't know about the vehicle being so dead 2 different tow trucks had to be called because even the tires were locked up. Just still receiving my messages I need to check my lights because my battery (NOT BATTERIES MULTIPLE) is low and it's not low, THEYRE ALL 3 DEAD. I was in a dangerous situation and always felt safe in a 2 yr old car with a full tank and hybrid battery backup and less than. 20k miles. IF EVER FIXED because service may have to send OUT OF STATE I will never buy a hyandai or hybrid again. The entire battery system broke down. Which killed the entire electrical system which now no one knows how to fix

The hybrid system flashes "Check Hybrid System" then the check engine and check HEV lights are illuminated. The vehicle loses power and even with the gas pedal pushed firmly to the floor the engine isn't producing power. This is a safety issue because I've lost power while driving on busy roads and can't clear the intersection, etc. This was reproduced at the dealership and Hyundai is performing a warranty replacement of the "hybrid system". I wanted to make NHTSA aware of the issue because on the Hyundai forums I'm seeing similar reports made. There is an open campaign to update the software for the hybrid system, 9B4, but this software update did not fix the issue.

Vehicle started jerking and sputtering. Loss of rapid acceleration. Check engine light came on. Did this at idle and all speeds.

- Columbus, MS, USA

The first incident was on 5/27/24 when I was traveling about 45 mph. The check engine light came on and the car started to shimmy and shake when I pressed the gas. Error code came up on the screen for P0304, injector #4 was bad. Had the vehicle towed to the closest dealer for warranty repair and was told this is a known issue but no recall has been placed. Then on 7/16/24, same thing happened while traveling out of town. Hyundai app was down so couldn't get an error code. Again had the vehicle towed to a dealer and this code was P0302, #2 injector was bad. Obviously there is a serious issue that needs to be addressed. Need to know if this is a permanent fix or if the other 2 will go out soon. I attached a photo of this report and can also get a copy of the one from May as needed.

A faulty fuel injector caused my Tuscon to lose all acceleration while I was in the passing lane of a 4-lane highway going 75mpg. A check engine light came on and it just bricked itself. I had to glide through 3 lanes almost causing a wreck. We were on a family vacation with our [XXX] daughter in the back seat and we had to wait over 2 hours in the blazing heat for a tow. The dealership said there is a known problem with the fuel injectors in these SUVs. I can't believe there isn't yet a recall for these fuel injectors. I'm concerned someone is going to get hurt because of this very fixable problem. Thanks for the help. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

NHTSA Complaint On Sunday, March 10th 2024 our 2022 Hyundai Tucson with 2.5L engine started missing in one of the cylinders. It did not disable the vehicle and it ran like that for several blocks until we could pullover to safety. At this time there were no warning lights of any kind. It wasn-??t until I turned the car off, checked the oil (which was good), started the car again and did a lap around the parking lot that the check engine light came on. So there were no warnings. We dropped the car off at our local Hyundai service center that night so it could be checked first thing the next day. It turned out that it was a bad spark plug and injector. At that point it was no big deal. We chalked it up to a fluke. We received the car back on Thursday, March 14th with the explanation of what happened and that it was replaced under warranty. There were NO RECOMMENDATIONS made upon pick up. Exactly 2 weeks later on Thursday, March 28th, the car lost all power while traveling 60mph in the middle lane of the interstate. Again, there were no warning or diagnostic lights coming on. It was pure luck that there was minimal traffic and other drivers were paying attention as the car came to a complete stop in the middle of the highway in order to be restarted and it refused to accelerate above 20mph in order to limp to the shoulder and get to safety. Over an hour later and stopping and starting the car in a parking lot, the check engine light finally came on. The engine was running worse this time. The car had to be towed this time to the service center. After being checked out it was another spark plug and a fouled fuel injector. Researching online showed that this is a very common issue with Hyundai fuel injectors between 12,000 and 25,000 miles. There are currently no technical service bulletins or recalls warning owners of this common failure and potentially losing power traveling at high speeds. Research showed there have been 3 collisions caused by this exact issue to date.

While driving, my vehicle suddenly lost all power and didn't respond to the accelerator. The "check engine" and "hybrid system failure" lights came on, jeopardizing my safety and that of other road users. The car overheats significantly, to the extent that the air conditioning only blows hot air. This situation forced me to pull over on the highway shoulder, creating an additional risk for everyone involved in traffic.

First incident: While driving on the highway, my vehicle began to vibrate intensely, jerking, lost acceleration and ultimately was unable to drive. Smelled burning.

I was able to get over to the side of the road. Luckily I wasn-??t far from home. Car had to be towed to dealer again Very unsafe and no recall from Hyundai.

On June 1, 2023 I was driving on a highway, suddenly lost the ability to accelerate, the car suddenly losing power and a warning message said to leave the road and have hybrid system checked. I pulled over, car idling, reentered highway only able to use low speed ( was 55 mph zone) to get to an exit a short distance away I had to be towed, the warning message still appearing at the dealership but no problem could be identified. This was an extremely dangerous situation, I have not had a problem like this again but remain concerned about a reoccurrence I have reached out to Hyundai about my concerns about 1) how roadside assistance was handled (response obtained) and 2) my concerns about this vehicle failure. I have reached out again this month to Hyundai, last contact they did not have the correct car or case number, have not called back since. This is case #21511789

This car has 36,000 miles, purchased new and serviced on schedule. The car is at the dealer for the third time since purchase. The first was a fuel injector issue/drivetrain error. The second time was a bad spark plug. The most current issue is another fuel injector. People on the internet have reported similar problems. The dealership has directed us to come get the car, which is unacceptable, because this is an engine error. I spoke to Hyundai Customer Car and they directed me to rent a car at my own cost and to not drive the car.

In the last 4 months my vehicle has had 2 bad fuel injectors. In both instances my check engine light came in while I was driving down the road. The vehicle shuttered and could not accelerate. Luckily both times J was close to home and was able to turn around. This came with no warning. Both times, I had previously driven the car that day with no issues. When I went out for another trip, the vehicle then had an issue. I am concerned the fuel injectors for this vehicle/model may have a defect of some kind, as I have lost two in a very short amount of time. If this happened in a congested area or highway it could absolutely present a safety issue. The first incident occurred when the vehicle had about 59,000 miles on it.
