2021 Genesis G80 Problems and Top Complaints – Is Your Car A Lemon?

Engine & powertrain issues are among the top complaints from vehicle owners

The Genesis brand is Hyundai’s answer to luxury vehicles. This leading South Korean car manufacturer envisioned the idea of a luxury sedan way back in 2004. But it took more than a decade for the idea to become reality.

The G80 and G90 models were the first Genesis sedans to launch in the U.S. in late 2016. The second-generation G80 was launched in 2020, and an electrified G80 was introduced in 2021.

U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) records reveal numerous consumer complaints about the first generation G80, many of which relate to engine problems. But perhaps the most alarming aspect is that just about every model is subject to an urgent fire risk recall.

Only implemented in March 2021, the urgent recall warns that an electrical short circuit in the anti-lock brake system module may occur in certain 2015 and 2016 Genesis vehicles and 2017-2020 G80 vehicles. This could result in an engine-compartment fire while the car is parked or on the road. As many as 94,646 vehicles could be affected.

While this recall doesn’t apply to the 2021 G80, there is a different recall that is also due to a fire risk. The problem is that in an estimated 147 vehicles, the fuel tube that connects the high-pressure fuel pump to the fuel rail might not seal properly. In the event of this malfunction, fuel could leak, increasing the risk of fire.

Most Common Problems with the 2021 Genesis G80

There are 3 complaints on file with the NHTSA about the 2021 G80. We are going to look at them all. One is categorized as an engine and powertrain issue and another as a problem with tires. The third, listed under Unknown or Other, complains about not being able to read text messages while driving.

There are additional problems reported on other platforms including Genesis owners’ forums and the Kelley Blue Book (KBB).

For example, complaints on the Genesis Forums website range from hard seats and “horrible” transmission to electrical problems including the battery not charging.

One lengthy complaint gives examples of multiple problems, including the battery going dead if the car isn’t started daily. “Genesis diagnostics show everything is operating normally. I am sure I have missed some of the glitches we have seen. Problems have been increasing and started out as intermittent. Most expensive disappointment ever.”

2021 Genesis G80 Engine & Powertrain Problems

This NHTSA complaint states that the owner of the G80 had engine/powertrain issues while driving at between 30 and 40 mph. “The transmission disengaged, and the vehicle stalled and restarted without warning.” This happened on two separate occasions.

A KBB consumer complaint gives the 2021 G80 3 stars, but only 1 out of 5 for quality and 2 for value. The “G80 looks great but is a giant step backwards,” the complaint says. “Bad build quality, rough engine, poor, poor ride.”

2021 Genesis G80 Tire Problems

The car referred to in the NHTSA Tires category complaint was equipped with Pirelli Scorpion STR tires. “While the vehicle was parked, the front passenger’s side tire had an inner sidewall blowout.”

The manufacturer referred the car owner to two dealers, presumably to have the tires replaced.

2021 Genesis G80 Text Message Errors

The complaint about text messages is from an owner who points out that, “the G80 is equipped with a Bluetooth system that should read incoming text messages while in Drive.” But it malfunctions.

“After I select ‘Listen’ the car tells me ‘unavailable while Driving.’ When I close this system message, the display shows the first several words of the text message – allowing me to read the message while in Drive. This is unsafe.”

This complaint also states that there are many other G80s with the same problem, and provides a Genesis Forums link that features multiple similar complaints.

“I have contacted Genesis USA several times with no luck. I have returned the car for service multiple times with no resolution.”
