Chevy Silverado And GMC Sierra Roof Rail Air Bag Could Rupture

Posted on by

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.

California Lemon Law Buyback For 2016 GMC Acadia

Posted on by

Our client bought a 2016 GMC Acadia,

In September our client took his Acadia to the authorized GMC Dealership because the A/C on the rear driver’s side and rear passenger side was blowing warm air.

The next visit was on September 25th because the check engine light was on and the vehicle seemed to be idling rough. After filling up the gas the vehicle did not want to start. Also, the A/C stopped working. A light would come on and flash but would not stay solid.

The vehicle was back at the dealership on October 17th because there was a hissing noise coming from the vents and the rear A/C was blowing warm air.

Our client was back at the dealership on December 20th because there was a noise coming from the engine. When turning off the vehicle there is a winding down noise. While using the A/C there is a bubbling noise. Also, the brakes were squeaking and making a bubble noise.

The next visit to the dealership for servicing was on February 6, 2019. The first concern was that when the vehicle was idling and the heater or A/C was on, it was making a bubbling noise. Another concern was the ambient lighting on the front passenger side was inop. The 12 volt charger in the rear was inop. When putting the lift gate up there is a very large clunking noise. The driver’s side door outer belt molding was deformed. The brake pedal was making noises.

The last visit was on February 19th and the ambient lighting on the passenger side by the glove box was inop. They were hearing a light bulb bubble noise from the dash. Also the A/C light button had flashed three times.

It was shortly thereafter that we heard from our soon to be client. They spoke with Barry and sent him some documents to review. Soon after they signed a retainer agreement and a demand letter was sent to General Motors Corporation to repurchase their vehicle under the California Lemon Law. GMC agreed to buyback the Acadia, pay off the balance, reimburse him for the down payment and any payments made, pay off the balance less the mileage fee allowed under the California Lemon Law. They also paid all the attorney fees.

Our client was very happy with the buyback of his vehicle. If you think you might be driving a lemon because of repeat problems that the dealership is unable to fix, please call 888-395-3666 for a free consultation.

GM 2nd Quarter Sales Increase 40 Percent

Posted on by

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.

2021 Cadillac, Chevrolet And GMC Trucks Steering Warning Indicator

Posted on by

General Motors has decided that a problem affecting vehicle steering exists in certain 2021 Cadillac, Chevrolet and GMC trucks. GM opened an investigation into the condition after receiving a field report of loss of power steering assist in a 2021 GMC Yukon.

According to the defect report, diagnostic trouble code (DTC) data obtained from the vehicle indicated that the power steering system may contain a software error that causes loss of power steering assist at startup or while driving. Vehicle testing demonstrated that manual steering remained available without power assist, but increased steering effort was required, particularly at lower speeds. In most cases, the malfunction indicator light will display on the instrument panel and a warning chime will sound. The condition is typically self-corrected at the next ignition cycle.

Vehicles Affected Include
2021 Cadillac Escalade
2021 Cadillac Escalade ESV
2021 Chevrolet Suburban
2021 Chevrolet Tahoe
2021 GMC Yukon
2021 GMC Yukon XL

GM will update the software in the vehicles’ power steering module. Owners will have the opportunity to accept these software changes using wireless over-the-air (OTA) technology without having to bring their vehicle to a dealership. Alternatively, owners may schedule to have the updates performed at a GM dealer. A certain number of vehicles that were part of GM’s captured test fleet will require replacement of the steering gear motor kit in order to receive the updated software.

GM’s number for this recall is N212333900 and the NHTSA campaign number is 21V-455.

Our client bought a 2018 Cadillac Escalade and was very happy.

His first visit was on December 13, 2018 to the authorized Cadillac dealership because the airbag light came on.

He was back at the dealership 3 months later on March 12th because the airbag light was on again.

Airbag Warning Light May Not Illuminate In GM Vehicles

Posted on by

General Motors has decided that a defect relating to vehicle safety exists in certain 2021 model year Buick, Cadillac, Chevrolet and GMC vehicles.

In April 2021, a Problem Resolution and Tracking System (PRTS) issue was opened following validation testing for a future model year vehicles, where it was noted some conditions in which loss of communication with the sensing diagnostic module (SDM) did not illuminate the airbag malfunction indicator lamp. GM opened an investigation in May 2021. A review of field data showed 19 warranty claims possibly linked to this condition.

According to the defect report, a software problem exists in some of these vehicles which would cause a SDM communications fault to illuminate the airbag malfunction indicator lamp, but only on alternating ignition cycles. As a result, an SDM communications fault would not consistently illuminate the airbag light on every ignition cycle to indicate a problem to the driver.

A driver might not be warned of an SDM loss of communication fault which might indicate a problem with airbag deployment. If airbags do not deploy appropriately in a crash, there is an increased risk of injury.

Description of the Cause : The Communications Gateway Module, also referred to as the serial data gateway module, software does not correctly store data indicating loss of communication with the SDM.

Vehicles Affected Include
2021 Buick Envision
2021 Cadillac CT4
2021 Cadillac CT5
2021 Cadillac Escalade
2021 Cadillac Escalade ESV
2021 Chevrolet Corvette
2021 Chevrolet Suburban
2021 Chevrolet Tahoe
2021 GMC Yukon
2021 GMC Yukon XL

GM dealers will correct the problem by updating the software for the communications gateway module. Owner notification letters are expected to be mailed in July 2021. GM’s number for this recall is N212338110 and the NHTSA campaign number is 21V-421.

Unsecured Side Curtain Air Bags Found In GM Vehicles

Posted on by

General Motors has decided that a safety defect affecting airbags exists in certain 2010-2015 and 2017 Buick Enclave, 2010-2019 Chevrolet Traverse and 2011-2016 GMC Acadia vehicles.

According to the defect report, in October 2020, a third-party vehicle repair business contacted GM requesting repair assistance on a 2018 Buick Enclave. After removing the headliner to attempt to repair a sunroof water leak, the repair shop identified two fasteners that were not installed and one missing weld nut attaching the roof-rail airbag (RRAB) to the vehicle. Further investigation found that certain stampings associated with the connection of the roof rail airbag to the vehicles had damaged, out of position or missing weld nuts. Although the problem was identified during vehicle assembly, the repairs may have been missed or preformed incorrectly.

GM will notify owners, and dealers will inspect and, if necessary, realign or replace the weld nuts GM’s number for this recall is N202321200 and the NHTSA campaign number is 21V246.

GM Airbags Investigated

Posted on by

The Office of Defects Investigation (ODI) have opened an investigation into certain 2020-2021 Cadillac, Chevrolet, and GMC vehicles because of a problem affecting the airbag system. The ODI have received fifteen complaints from consumers who say that the air bag system in their GM vehicle malfunctioned. Nine complaints allege the illumination of an air bag malfunction indicator (MIL) and six crash incidents had significant frontal collision damage but the driver frontal air bags failed to deploy. All the complaints received involve either GM vehicles covered by GM Technical Service Bulletin (TSB) 21-NA-005 or CT4, CT5 and XT4 vehicles.

The TSB, issued in March 2021, addresses air bag MIL illumination accompanied by diagnostic trouble codes B0001-1B or B0012-0D. It also cites rust particles in the connection terminal interface of the driver air bag inflator as the cause of the air bag MIL illumination. Illumination of the air bag MIL under these circumstances may result in a non-deployment of the driver airbag during a frontal collision and increased risk of injury to the driver.

ODI is opening this preliminary investigation to determine the scope and severity of the potential problem and to fully assess the potential safety-related issues.
