GMC Hummer EV recalled over faulty taillamp embedded software issue

Update: GMC has informed Teslarati That following the recall decision on March 3, 2022, the automaker’s representatives contacted customers with affected vehicles and made necessary arrangements to replace the taillamps on the Hummer EV. All 10 vehicles affected by the recall have been rectified in writing.

General Motors (GM) has decided to initiate a recall on issues surrounding the vehicle’s taillamps for the 2022 GMC Hummer EV. A safety recall report from the National Highway Traffic Safety Administration (NHTSA) says the problem is linked to software embedded in the microcontroller of the Hummer EV’s taillamp assembly.

According to a description of the non-compliance outlined in NHTSA’s safety recall report, the affected Hummer EVs do not conform to Federal Motor Vehicle Safety Standard (FMVSS) number 108, which refers to regulations surrounding “lamps, reflective devices and related equipment”. Is. Software embedded in the taillamp can cause one or two of the Hummer EV’s taillights to either idle or partially illuminate.

In the event that the Hummer EV’s taillamp is idle, all component-related functions – such as brake lights, turn signals, backup lamps, side markers, clearance lamps and taillights – will eventually be disabled. Such a problem could potentially reduce the visibility of the vehicle or give false information to other drivers on the road, increasing the risk of accidents.

According to the chronology of the issue outlined in NHTSA’s Safety Recall Report, a GM employee reported on February 1, 2022 at the company’s Speak Up for Safety (SUFS) program about two field incidents involving Hummer EV units with faulty taillamps. presented. A product investigation was opened on February 11, 2022, and on March 3, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a non-compliance recall for the affected vehicles.

Interestingly, only ten Hummer EVs are expected to be affected by the taillamp recall. The automaker noted that it was aware of three field complaints about the issue so far, which it received from January 8, 2022 to February 7, 2022. The company noted that till date no accident has been linked to the taillamp recall of the Hummer EV.

To resolve an embedded software issue in affected Hummer EV units, GM dealers will inspect and replace the left and/or right rear taillamp assemblies of a fully electric vehicle. These replacement taillamp assemblies feature software embedded right into their microcontrollers, which should resolve taillamp problems.

It should be noted that GM’s assembly plant began containment efforts for the issue of the Hummer EV on February 9, 2022. As such, Hummer EV units with manufacturing dates after January 20, 2022 were already built with taillamp assemblies that have corrected software.

Tesla Model Y welcomed by Kansas PD, expected to give cost savings – Elon Musk - Elon Musk

In a recent press release, the Leawood Police Department in Kansas announced that it had acquired a Tesla Model Y Long Range for its fleet. The vehicle would be used as one of the Leawood PD’s patrol cars. The Model Y has already been painted in the Leawood PD’s black and white colors. The department noted that they started looking into the idea of an all-electric patrol car last year after seeing dismal reviews of available hybrid patrol cars. Captain Kirt Yoder, the agency’s project manager, noted that Tesla Kansas had been quite helpful. “I ended up contacting about ten agencies from New York to California. Tesla-Kansas City was great. They were eager to help and answer all our questions,” he said. Apart from being a green vehicle, the Model Y is also expected to give the Leawood Police Department substantial cost savings. Over a year ago, a cost comparison already showed that the department’s Ford Explorer patrol SUV would cost about $4,500 per year to run. That was a time w...

Sen. Joe Manchin blasts EV tax credit expansion, calls for hydrogen development

West Virginia Democrat Joe Manchin blasted a potential expansion of the electric vehicle (EV) tax credit on Thursday, while also calling for the development of the hydrogen sector to decarbonize the transportation industry. Manchin, who called a Biden administration proposal to broaden the EV tax credit program “ludicrous,” said the waiting period for EVs right now is already so long that there is no point to offering more money to incentivize consumers to buy a battery-powered car. “There is a waiting list for EVs right now, with the fuel prices, but they still want us to throw a $5,000, or $7,000 or $12,000 credit for us to buy electric vehicles,” said during a Thursday Senate budget hearing. Manchin added that production volumes of EVs are far away from fulfilling current demand levels, so it would be ridiculous to offer additional funding to the programs. It is evident that EVs are becoming more popular, and with automakers in nearly all situations relating to EVs still workin...
