GMC Hummer EV recalled over faulty taillamp embedded software issue
UPDATE: GMC has informed Teslarati that following the recall decision on March 3, 2022, representatives from the automaker contacted customers with affected vehicles and made the necessary arrangements to replace the taillamps on the Hummer EVs. All 10 vehicles that were affected by the recall have been fixed as of writing.
General Motors (GM) has decided to initiate a recall for the 2022 GMC Hummer EV over issues surrounding the vehicles’ taillamps. A Safety Recall Report from the National Highway Traffic Safety Administration (NHTSA) stated that the issue is linked to the embedded software in the microcontroller of the Hummer EV’s taillamp assembly.
According to the description of noncompliance outlined in the NHTSA’s Safety Recall Report, affected Hummer EVs fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) No. 108, which refers to regulations around “lamps, reflective devices, and associated equipment.” Embedded software in the taillamp can cause one or two of the Hummer EV’s taillights to either become inoperative or partially illuminated.
In the event that the Hummer EV’s taillamp is inoperative, all functions related to the component — such as brake lights, turn signals, backup lamps, side markers, clearance lamp, and taillight — would end up being disabled. Such an issue could potentially reduce the visibility of a vehicle or communicate incorrect information to other drivers on the road, leading to an increased risk of accidents.
According to the chronology of the issue outlined in the NHTSA’s Safety Recall Report, a GM employee submitted a report about two field incidents involving Hummer EV units with malfunctioning taillamps to the company’s Speak Up For Safety (SUFS) program on February 1, 2022. A product investigation was opened on February 11, 2022, and on March 3, GM’s Safety Field Action Decision Authority (SFADA) decided to perform a noncompliance recall for affected vehicles.
Interestingly enough, only ten Hummer EVs are expected be affected by the taillamp recall. The automaker noted that it was aware of three field complaints about the issue so far, which were received from January 8, 2022 through February 7, 2022. The company noted that no accidents have been connected to the Hummer EV’s taillamp recall to date.
To address the embedded software issue in the affected Hummer EV units, GM’s dealers would inspect and possibly replace the all-electric vehicle’s left and/or right rear taillamp assemblies. These replacement taillamp assemblies feature corrected embedded software in their microcontroller, which should address the taillamp problems.
It should be noted that GM’s assembly plant initiated containment efforts for the Hummer EV’s issue on February 9, 2022. As such, Hummer EV units with build dates after January 20, 2022 were already built with taillamp assemblies that have corrected software.

Tesla launches Powerwall Lease for affordable home backup
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk teases Tesla Roadster unveiling once again
Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes
— Elon Musk (@elonmusk) August 12, 2026
The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”
We took a ride on a robotaxi on the Suntrax course and it successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.
Impressive! https://t.co/FVAkzFLz3r
— Ron DeSantis (@RonDeSantis) August 11, 2026
DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.
Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
