This is an expansion of NHTSA Recall 20V-701 and 21V-560.

General Motors has decided that a defect which relates to motor vehicle safety exists in 2020-2022 Chevrolet Bolt EVs and 2022 Chevrolet Bolt EUVs. The high voltage batteries in these vehicles may pose a fire risk when charged to full, or very close to full, capacity.

Defective battery modules will be replaced, but until then, GM advises owners to Activate either the Hill Top Reserve (2017 and 2018 models) or Target Charge Level (2019 models) feature in their vehicle to limit the charge level to 90%, charge their vehicle more frequently, avoid depleting the battery to 70 miles range remaining, park outside after charging, and do not charge the vehicle indoors overnight.

Interim notification letters notifying owners of the safety risk were mailed on August 13, 2021. Owner notification letters were mailed on August 13, 2021. GM’s number for this recall is N212343880 and the latest NHTSA campaign number is 21V-650.

In March 2021, a safety report was submitted to GM’s Speak Up for Safety program regarding a warranty claim affecting the seat belt on a low mileage 2021 Cadillac XT4. The customer’s complaints included a rattling noise coming from the passenger side rear seat belt. The rattle could be heard while driving or when attempting to use the seat belt. The dealer determined that the noise was caused by a missing lower fastener in the retractor assembly. A search for similar allegations discovered three additional potentially related claims also involving XT4 vehicles. In each case, the complaint was a rattling noise that was determined to be caused by a loose or missing fastener in a rear seat belt retractor.

An investigation also revealed that 2016-2021 Chevrolet Malibu vehicles were assembled at the same place using the same right-hand rear side assembly process and added these vehicles to the investigation. Data for the entire population of approximately 1.4 million 2019-2021 XT4 and 2016-2021 Malibu vehicles produced at Fairfax found no additional related claims.

Investigator analysis of the repair procedure determined that the procedure could have been the cause of the loose or missing fasteners under a specific set of circumstances that was unlikely to occur, but possible. The investigator retrieved plant manufacturing records to determine whether other vehicles were subject to similar repairs. Those records identified 437 such vehicles out of the total population. Testing was also conducted that determined it was possible for the condition to be present with the absence of warning noises, even though each of the three relevant field reports did describe audible warning signs.

Although no additional related claims were found, GM have decided to conduct a recall.

According to the defect report, GM will be recalling certain 2016-2021 Chevrolet Malibu and 2019-2021 Cadillac XT4 vehicles manufactured at their Fairfax plant. Dealers will inspect the rear seat belt retractors and tighten them as necessary. GM’s number for this recall is N212333380 and the NHTSA campaign number is 21V-649.

General Motors have decided that a defect affecting vehicle safety exists in certain Hankook tires installed as original equipment on some 2021-2022 Chevrolet Equinox and GMC Terrain vehicles.

In July 2021, GM’s Speak Up For Safety program received information that two tires, received through GM warranty return, had suffered delamination. In June, the owner of a 2021 GMC Terrain brought their vehicle to a GM dealer with complaints of vibration and thumping noises while driving. The dealership noted that the owner had a previous issue with a tire on a road trip that resulted in tire replacement. Both tires were shipped to the supplier. GM became aware of a third tire potentially related to this condition in July. All three tires were from DOT number 0521. GM initiated a yard hold and sort for vehicles equipped with tires from that DOT number. Through testing Hankook determined that the delamination was caused by an insufficient amount of curative agent in a particular batch of rubber. In July Hankook informed GM that they intended to issue a tire recall. GM is not aware of any accidents or injuries associated with this condition and have decided to conduct a safety recall.

Delamination of tread may occur at high speeds. The tire will likely not deflate or burst, but the tread separation might compromise vehicle handling and/or cause a crash. Warning signs that your tires are delaminated include noise or feel vibration while driving and/or a bulge in the tread may also be noticeable.

Dealers will inspect the tire DOT numbers and replace any affected tires. GM’s number for this recall is N212343560 and the NHTSA campaign number is 21V-612.

If you are a Chevy Bolt owner living in California and you received a recall notice for battery fires, you may find it difficult to park your vehicle.

General Motor’s recent recall of certain 2017-2019 Chevy Bolt EVs is caused by the presence of two manufacturing defects in the N2.1 battery cell produced at their Korea facility. The problem is aggravated by charging the battery to a full or nearly full state of charge after it has been substantially depleted. The battery could overheat, emit smoke and catch fire, causing damage to vehicle components and structures around it. As a temporary solution, GM have asked owners to reprogram their hybrid propulsion control module to limit a full charge, but some owners say they are experiencing problems.

The safety recall from the NHTSA states the following:

As an interim remedy, dealers will reprogram the hybrid propulsion control module to limit full charge to 90%. Until this interim is completed, customers should enable either “Hilltop Reserve” (for 2017-2018 model year vehicles) or “Target Charge Level” (for 2019 model year vehicles) using their vehicle’s infotainment center. These two features will limit the vehicle’s state of charge to 90% until the HPCM2 software re-calibration is applied. If customers are unable to successfully make these changes, or do not feel comfortable making these changes, they will be advised to not park their car in their garage or carport until after they have visited their dealer.

What options does that leave you? Possibly parking your car on the street or driveway which has problems in itself. Most charging cables are not long enough to reach the street, the cables could be damaged or stolen or someone could trip on them. Also in some cities there are restrictions against parking in the street and driveways.

In mid-June 2021 General Motors became aware of roof rail airbag (RRAB) inflator ruptures in three 2015 model year Silverado vehicles while the vehicle was unoccupied and not in use. In all three incidents, the steel inflator body sidewall split open, suddenly releasing the gas stored inside the chamber. GM’s Safety and Field Action Decision Authority have decided to conduct a safety recall.

According to the defect report, The RRAB inflators on the left and right side roof rails may contain a manufacturing defect that could result in inflator end cap separation or inflator sidewall split. If this happens, the compressed gas will escape from the inflator and the end cap or other components can be propelled into the vehicle, potentially injuring occupants.

The Cause Of The Problem: Corrosion inside the inflator vessel, which was caused by moisture introduced into the vessel during the supplier’s manufacturing process and aggravated by
thermal cycling in high-temperature climate regions

Vehicles Affected Include
2015-2016 Chevrolet Silverado 1500
2015-2016 Chevrolet Silverado 2500
2015-2016 Chevrolet Silverado 3500
2015-2016 GMC Sierra 1500
2015-2016 GMC Sierra 2500
2015-2016 GMC Sierra 3500

Dealers will replace the left and right side RRAB modules. Interim owner notification letters informing owners of the safety risk are expected to be mailed August 16, 2021. Owners will receive a second notice when the remedy is available. This recall supersedes NHTSA recall number 20V-736. GM’s number for this recall is N202324251 and the NHTSA campaign number is 21V-504.

General Motors have identified a problem affecting certain 2017-2019 Chevrolet Silverado and GMC Sierra 2500/3500 trucks manufactured with the Duramax diesel 6.6 litre engine and the optional block-heater power cable.

Contamination of the sealing surface of the block-heater heater element can allow a coolant leak to develop. If leaking coolant contacts the block heater cable terminals while the cable is plugged into an energy source a short could occur.

In February 2021, a GM quality manager submitted a report to GM’s Speak Up For Safety program after inspecting an engine-block heater recovered from a 2019 model year Chevrolet Silverado 3500. The owner reported sparking from under the hood after the engine block heater was plugged in. The block heater was leaking coolant, and the engineer observed thermal damage at the connection between the heater and the block heater power cable. This vehicle had previously been fixed for this condition under NHTSA recall 19V-328.

Further investigation identified nineteen potential fires involving engine-block heaters in vehicles remedied under 19V-328. Based on this data, GM opened a formal product investigation and found 122 complaints and 24 reports of potential fires between December 3, 2019 and May 28, 2021 involving vehicles that received the recall remedy under 19V-328. Based on this data GM decided to conduct a safety recall on these vehicles.

Vehicles Affected Include
2017-2019 Chevrolet Silverado 2500
2017-2019 Chevrolet Silverado 3500
2017-2019 GMC Sierra 2500
2017-2019 GMC Sierra 3500

Dealers will disable the block heater. GM will provide free replacement block heaters and cords under a separate customer satisfaction campaign. For vehicles previously included in recall 19V-328, the heater cord will be replaced and rerouted. Owner notification letters are expected to be mailed August 16, 2021. GM’s number for this recall is 212329840 and the NHTSA campaign number is 21V-496.

General Motors will be contacting the owners of certain 2021 Chevrolet Traverse and 2021 Buick Enclave SUVs, about a problem that could result in the front air bag not deploying properly. Owner notification letters are expected to be mailed out beginning of August 2021.

According to the defect report, during a weekly service programming system (SPS) audit, it was discovered that a small number of 2021 Chevy and Buick models may have been manufactured with the incorrect sensing diagnostic module (SDM) data calibration. The data files were corrected in the SPS system and the problem was reported to GM’s safety program. Their investigation found a small number of 2021 Chevrolet Traverse and 2021 Buick Enclave vehicles may have received the same incorrect data and decided to conduct a safety recall.

General Motors will be contacting the owners of affected vehicles with instructions to update the calibration software in the SDM. GM’s number for this recall is N212340220 and the NHTSA campaign number is 21V-472

General Motors Co. (NYSE: GM) announced it sold 688,236 vehicles in the U.S. in the second quarter of 2021 – an increase of 40 percent compared to a year ago – in a unique market bolstered by strong customer demand, but constrained by low inventories resulting from the global semiconductor shortage.

“The U.S. economy is accelerating, consumer spending is robust and jobs are plentiful,” said Elaine Buckberg, GM chief economist. “Consumer demand for vehicles is also strong, but constrained by very tight inventories. We expect continued high demand in the second half of this year and into 2022.”

“The agility and creativity of our supply chain, purchasing, engineering and manufacturing teams, in collaboration with our suppliers and dealers, have helped us continue to satisfy customers and gain market share in some of the highest demand segments of the market,” said Kurt McNeil, U.S. vice president, Sales Operations.

GM is well positioned in 2021 to lead the industry in full-size and mid-size pickup sales for the seventh consecutive year. During the quarter, GM earned 40.6 percent of the retail market for full-size pickups, up 4.5 percentage points year over year (J.D. Power PIN), with more than 237,000 Chevrolet Silverados and GMC Sierras sold in the quarter.

The company is taking steps to meet customers’ future needs, especially in capacity-constrained segments:

GM announced that production of HD pickups will increase by about 1,000 trucks per month beginning in mid-July as a result of production line efficiencies delivered by the team at Flint Assembly in Michigan.
Also, GM will return full-size pickup production to Oshawa Assembly in Canada at the end of 2021.
Shipments of Chevrolet Colorado and GMC Canyon mid-size pickups built at Wentzville Assembly in Missouri increase by about 30,000 total units from mid-May through early July as the team completes dynamic vehicle testing on units held at the plant due to semiconductor supply disruptions.

GM ended the quarter with 211,974 units in inventory, down from 334,628 at the end of the first quarter.

  • Chevrolet Bolt EV delivers record second-quarter and first-half deliveries.
  • Buick sales rise 86 percent on strong demand for new Encore GX, redesigned Envision, and Enclave, creating the brand’s best quarter in more than 15 years.
  • GMC records best second quarter and best first half since 2005 driven by Yukon and Yukon XL.
  • Chevrolet Silverado and GMC Sierra sales up a combined 36 percent, with light-duty models posting strong segment share gains.
  • Cadillac’s second quarter retail sales were its best since 2015.
