Certainly, the GMC Hummer EV is cool, potent, and expensive, but at the same time, it is not without flaws. Some purchasers are complaining about the vehicle.
According to some GMC Hummer EV owner forum posts, drivers face problems with their vehicles such as moisture ingress into the electrical system, busted tail light, poor sealing of roof panels that causes leakage inside the cabin, and the same problem with A-pillar seal, when water soaked into the switch bank.
Malfunctioning roof panels dissatisfied customers much. They’ve been complaining that the roof seals collect water instead of letting it drain away, and after the roof panel removal, water flows inside the vehicle. Some say the seals close improperly.
To solve this ‘roof panel issue’, GMC even proposed a Customer Satisfaction Program (CSP) at dealerships. Dealers have already started accepting the affected vehicles for repair.
General Motors introduced the GMC Hummer EV SUT (a pickup truck) in October 2020, while an SUV version’s unveiling happened last April.
Though the model gained popularity and it can boast an impressive waiting list (77K orders as of July 2022), a small number of deliveries were: 1 unit in Q4 2021, 99 units in Q1 2022, and 272 units in the second quarter of this year.
The point is that due to supply chain issues, the automaker produces just about 12 vehicles a day, lagging behind similar offerings from Rivian or Ford.
We must admit that quality issues in addition to production restraints are not what we expected from the Hummer EV.
