2018 Genesis G80 Electrical Problems

I am writing to formally report a serious safety defect in my Genesis vehicle and to request immediate investigation, documentation, and corrective action. Following a recent crash event, my vehicle’s diagnostic scan revealed DTC B1378, which is associated with a fault in the airbag system circuitry. This code is widely recognized as an indicator of an airbag defect and is consistent with conditions that warrant manufacturer recall. During the crash: - Multiple airbags deployed, - The steering‑wheel airbag did NOT deploy, - The SRS system recorded a crash severe enough to trigger other airbags, - The vehicle now displays B1378, confirming an internal fault. The failure of the primary driver airbag to deploy during a crash is a critical safety malfunction. Combined with the presence of B1378, this raises substantial concerns regarding a defective airbag module, wiring harness, or sensor — all of which fall under manufacturer responsibility and federal safety standards. I am requesting the following: Immediate corrective action, including repair or replacement of all defective components. Documentation of this issue in your internal safety‑defect tracking system. Given the severity of this failure and its implications for driver safety, I am also submitting this information to the National Highway Traffic Safety Administration (NHTSA) for review. Please confirm receipt of this letter and provide a written response outlining the next steps. Sincerely, [XXX] Hagerstown, MD --- INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There is a known issue with these vehicles where the Oil Pressure Sensor/Switch triggers at idle and low RPMs but nothing is necessarily wrong other than the sensor itself. However, since the sensor malfunctions, owners can’t know if the pressure is actually bad or if oil levels are normal. This is a safety concern for all owners. However, Genesis is requiring owners to pay around $3000 to repair this. Most of the models are 2017-2019, which are past its manufacturer warranty years.

1-THE STEERING WHEEL AIRBAG FAILED TO DEPLOY DURING A COLLISIOM WHILE ALL OTHER AIRBAGS `AIRBAGS INCLUDING REAR SEAT AIRBAGS -DID DEPLOY. THIS SUGGEST A POSSIBLE MALFUNCTION IN THE AIRBAG CONTROL MODULE STEERING WHEEL AIRBAG UNIT OR SENSOR SYSTEM. **YES THE VECHCLE IS AVAILABLE FOR INSPECTION BY GENESIS, NHTSA, OR ANY AUTHORIZED PARTY. 2. AS THE DRIVER I WAS AT DIRECT RISK THE STEERING WHEEL AIRBAG IS DESIGNED TO PROTECT THE HEAD AND CHEST IN A FRONTAL COLLISION. ITS FAILURE TO DEPLOY LEFT ME VULNERABLE TO IMPACT WITH THE STEERING WHEEL AND DASHBOARD. THE LACK OF DEPLOYMENT HAS WORSED THE OUTCOME 3. NOT YET I AM SEEKING A DIAGNOSTIC SCAN FROM GENESIS - CERTIFIED DEALER TO CONFIRM THE FAILURE AND IDENTIFY ANY FAULT CODES IN THE AIRBAG SYSTEM. 4. THE VEHICLE IS BEING ASSIGNED TO AN AJUSTER BUT NOT YET BY GENESIS OR NHTSA. I AM REQUESTING A FORMAL INSPECTION BY GENESIS AND WILL PROVIDE ACCESS TO THE VEHICLE. 5. THERE WAS NO WARNING LIGHTS OR MESSAGES PRIOR TO THE INCIDENT. 6. I WAS NAVIGATING A TURN WHEN A DEER ENTERED THE ROADWAY I SWERVED AND THE FRONT RIGHT WHEEL BECAME STRUCK CAUSING ME TO STRIKE AN EMBANKMENT. THE CONTROL ARM BROKE AND THE IMPACT TRIGGERED FULL AIRBAG DEPLOYMENT INCLUDING REAR SEAT AIRBAGS BUT NOT THE STEERING WHEEL AIRBAG Based on the severity and location of the impact, the steering wheel airbag should have deployed. I believe this failure may be due to a sensor malfunction or defect in the airbag system. This raises concerns regarding the reliability of the vehicle’s safety mechanisms, as the absence of steering wheel airbag deployment during such a significant frontal impact posed a serious risk to driver safety.

A/C does not work as blower will not put out cold air. During hot days in Florida with children and elderly in the car this poses a risk to our health. This happens when A/C has been on for approximately one hour. No warning messages whatsoever. This has been reported by many Genesis G80 owners who own a G80 from the years 2017 - 2020. Genesis Corporate is aware of the problem but has not submitted a recall.

Oil light keeps coming on suddenly, I looked online and there are many people who have had the same issue. It's only intermittent, and turns off when moving and turns on when idle. The first time it came on was when I was crawling on a first time in forever frozen Alabama road. I was very careful not to start sliding, and when the sign came on I panicked and ended up in a ditch. The safety issue comes from not knowing if this is a sensor issue or an actual oil issue. Most people stated that it was a sensor issue but to replace it, you must access inside of the motor.

For over one year we have been in contact with Round Rock Genesis in Round Rock, Texas about recalls # 254 & 018G (NHTSA Recall # 24V107000). Our Genesis G80 is now 6 years old. Failure to address this repair poses a risk of the car bursting into flames with no warning; Genesis advises parking the car outside. These recalls have not been performed because the dealership claims that they cannot get the needed parts. Recalls # 201 and 006G are meant to address the anti-lock braking system. Failure to address these recalls poses a risk of brake failure and fire. Because the service department of Round Rock Genesis have failed to ever call us back despite many messages left for them, we are not sure if this is still a current recall on this vehicle.

Whenever I drive long distance like 1 or more hours, AC has problem. It worksd fine in short local distance. I see a lot of drivers have the same issue if you click the link below. During the hottest season, it can become very dangerous. I live in San Angelo, TX, and there is no Genesis dealership in here. Hyundae dealership couldn't figure it out. The nearest Genesis dealership takes 3 hours from my house. I paid for extended warranty which will expire within 4 months, and its useless unless it can get fixed. [XXX] (It's not a easy fix to Genesis service.) Please help me to resolvbe the issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The oil pressure light comes on intermittently - often at low RPMs and then goes away at higher RPMs. It is a very expensive repair and appears to be just due to a faulty oil pressure sensor. The light causes issues because it covers up whether there is another more serious problem that needs attention.

THE GPS, RADIO AND OTHER ELECTRONIC NOTIFICATION SYSTEM ARE MALFUNCTIONING SUCH THAT THEY EITHER FREEZE UP OR GIVE ERRONEOUS INFORMATION BEGINNING WITHIN MINUTES AFTER THE CAR IS STARTED. THIS HAS BEEN GOING ON FOR SEVERAL WEEKS AND THE DEALER' S SERVICE DEPARTMENT CLAIMS IT IS A PROBLEM WITH SIRIUSXM AND OUT OF THEIR HANDS TO FIX. HOWEVER, A GOOGLE SEARCH REVEALS NO EVIDENCE THAT SIRIUSXM IS HAVING ANY TRANSMISSION PROBLEMS AND IT STILL WOULD NOT EXPLAIN THE WIDESPREAD ELECTRONIC MALFUNCTION. THE DEALER CAN NOT SAY WHEN THIS PROBLEM WILL BE SOLVED.
