2019 Hyundai Tucson Top Complaints and Problems – Is Your Car A Lemon?

Fuel system, powertrain and engine issues among the top complaints received by the NHTSA from vehicle owners

Hyundai has become known for its lineup of compact SUVs. The 2019 Hyundai Tucson is hailed as one of the top choices, with the newer models considered to be “the new standard.” Yet, a quick investigation reveals something horrible. It turns out that the Tucson suffers from massive engine, powertrain and fuel system failures that put occupants at risk.

Engine

In any vehicle, the engine serves as the main component that proves whether a model is reliable or not. When this part doesn’t operate the way it should, nothing seems to go right.

That’s exactly what’s revealed in this NHTSA complaint. “Sporadic hesitation when starting from a complete stop. This has happened to me about 15 times, usually when pulling out into traffic. The car has 4000 miles and has been in service about 6 months. The service manager stated that they have no other complaints but is probably due to the ‘smart’ transmission adapting to different drivers. I understand there was a recall for 41,000 2017 Tucsons for the same issue.”

There might have been recalls on earlier models, but none have been released for the 2019 Tucson yet. Still, the automaker can’t hide the engine troubles, especially with Service Bulletin #19-01-002H-4 floating around that discusses severe engine damage in the new SUVs. To combat this, the manufacturer released a new knock sensor software to attempt and head off the problem. In the meantime, Hyundai owners across the nation are driving SUVs that will face an engine failure. Hopefully, the warranty covers it for them, but who wants to deal with this when driving a new SUV?

Here are some actual complaints logged with the NHTSA about the 2019 Hyundai Tucson Engine Problems:

1.3 MILES AWAY FROM THE DEALERSHIP I PURCHASED THE 2019 HYUNDAI TUCSON IT STARTED TO SMOKE. 5 MINUTES LATER IT WAS ON FIRE!! IT HAD LESS THAN 400 MILES ON IT AND I?VE YET TO FIND OUT WHAT EXACTLY CAUSED THE FIRE. HYUNDAI OR THE DEALERSHIP WON?T TELL ME. THE FIRE CAME FROM THE PASSENGER SIDE UNDER THE HOOD. THE VEHICLE STARTED SMOKING WHEN I ATTEMPTED TO START IT AND CAUGHT ON FIRE WHILE OFF.

Powertrain

In conjunction with the engine, the powertrain seems to create the same issues. The transmission just can’t seem to provide a comfortable acceleration.

This NHTSA review states, “2019 Hyundai Tucson Limited. Sporadic hesitation acceleration from starting from a complete stop. I’ve had the car since June and have less than 3,500 miles on it. When you start from a red light the car will jerk and hesitate, almost like it’s out of gas but then in the middle of the intersection it will accelerate like normal. This has only happened to me while in normal driving mode. It hasn’t done this while in Sport or Manual shifting mode. I had to select a date of when this happened but it originally started around mid-July and sporadically to this day. It happens randomly but when it does it happens at consecutive stop lights and multiple times on the same day. This isn’t a DCT, so Hyundai, nor the dealer can say I’m driving the car incorrectly. Pretty disappointing to have my first ever brand new car have a serious issue like this.”

Again, this isn’t the only powertrain issue either. Hyundai talks about slipping with Service Bulletin #19-AT-012H. It might even require a repair to the transaxle, which is just another thing that new car owners should not have to deal with. If this is the “new standard” it might be better to go with the tried and true older models.

Here are some actual complaints logged with the NHTSA about the 2019 Hyundai Tucson Transmission Problems:

2019 HYUNDAI TUCSON LIMITED. SPORADIC HESITATION ACCELERATION FROM STARTING FROM A COMPLETE STOP. I’VE HAD THE CAR SINCE JUNE AND HAVE LESS THAN 3500 MILES ON IT. WHEN YOU START FROM A RED LIGHT THE CAR WILL JERK AND HESITATE, ALMOST LIKE IT’S OUT OF GAS BUT THEN IN THE MIDDLE OF THE INTERSECTION IT WILL ACCELERATE LIKE NORMAL. THIS HAS ONLY HAPPENED TO ME WHILE IN NORMAL DRIVING MODE. IT HASN’T DONE THIS WHILE IN SPORT OR MANUAL SHIFTING MODE. I HAD TO SELECT A DATE OF WHEN THIS HAPPENED BUT IT ORIGINALLY STARTED AROUND MID JULY AND SPORADICALLY TO THIS DAY. IT HAPPENS RANDOMLY BUT WHEN IT DOES IT HAPPENS AT CONSECUTIVE STOP LIGHTS AND MULTIPLE TIMES ON THE SAME DAY. THIS ISN’T A DCT, SO HYUNDAI, NOR THE DEALER CAN SAY I’M DRIVING THE CAR INCORRECTLY. PRETTY DISAPPOINTING TO HAVE MY FIRST EVER BRAND NEW CAR HAVE A SERIOUS ISSUE LIKE THIS.

Fuel System

When it comes to the fuel system in this vehicle, it’s clear that this system is just making matters even worse.

Another NHTSA complaint says, “I purchased a new 2019 Hyundai Tucson Ultimate this May. In the first week the Service Engine lit up. I took it to dealer and 2 days later the vehicle was returned as fixed. Based on dealer’s resolutions it was an evap leak code and they just had to replace the cap. Week later the sign came back again and I dropped off vehicle for another 4 days, dealer stated it was same code again and it won’t happen again. I took it back and two weeks later the light came back on again and disappeared after three days. The fourth time light came back again and I will be dropping off the vehicle again. The dealer is still unable to find the cause and unable to fix the issue. Based on the discussion with service manager, it is a minor problem for them, but the issue keeps coming back and I have to keep bringing the vehicle back to the dealer to fix it.”

This is one situation that Hyundai doesn’t want to discuss. It’s possible that the company already gave up enough information by talking about the engine and powertrain troubles. Instead, customers are left to speculate about what might be wrong with the fuel system. One thing is for sure; this model is not “the new standard.” If it is, it might be time to start taking the bus to work instead.

Here are some actual complaints logged with the NHTSA about the 2019 Hyundai Tucson Fuel System Problems:

VEHICLE STOPPED AND CUT OFF COMPLETELY IN THE MIDDLE OF THE BUSY INTERSTATE. ACCELERATION SLOWED UNTIL VEHICLE DIED AND ALL ERROR LIGHTS APPEARED AND FLASHED ON DASH WITH A “SERVICE NOW” ALERT. PLACED THE VEHICLE IN PARK, AND TURNED THE SWITCH TWICE BEFORE IT WOULD CRANK AGAIN. UPON STARTING- THE SAME “SERVICE NOW” LIGHT APPEARED AND CAR WAS ABLE TO DRIVE. “SERVICE NOW” LIGHT VANISHED ABOUT 10 SECONDS AFTER VEHICLE WAS DRIVING AGAIN.

UNCONTROLLED SPEEDING. HARD IMPACT ON BUMP VERY LOW SUSPENSION SYSTEM. HIGHER MPG THAN ADVERTISED

I.e. from September to june it is summer sunny season and july and august is rainy season. So i drove the care smoothly till july and now i have found the car leaks the water from the rain from the roof!!!! I am very disappointed. It has sun roof but the leakage is from the side of the rear mirror.
