General Motors vehicles recalled for potential fuel leaks

Warren, MI– December 10, 2020 – General Motors (NYSE:GM) has recalled 194,105 vehicles due to missing bolts on the start-stop accumulator end cap. The missing bolts may result in a transmission oil leak, a loss of vehicle power or an engine fire. This General Motors (GM) recall includes:

  • 2018-2019 Chevrolet Cruze sedans
  • 2018-2019 Buick LaCrosse sedans
  • 2018-2020 Chevrolet Equinox SUVs
  • 2018-2020 Chevrolet Traverse SUVs
  • 2018-2020 GMC Terrain SUVs
  • 2018 Chevrolet Malibu sedans
  • 2019-2020 Buick Encore SUVs
  • 2019-2020 Buick Enclave SUVs
  • 2019-2020 Cadillac XT4 SUVs
  • 2019-2020 Chevrolet Blazer SUVs
  • 2019-2020 GMC Acadia SUVs
  • 2020 Cadillac XT6 sedans

Recall summary  

Your vehicle’s transmission is designed to transfer engine power to the driveshaft. The start-stop accumulator shuts down the engine when it is not in use to achieve better fuel economy and cut down on emissions.

Each start-stop transmission accumulator is attached using four bolts. In the case of the recalled vehicles, due to a supplier software error, two of the required bolts are missing


Missing bolts can create a number of issues:

  • Transmission oil leak: A leak may damage other engine parts, and driving the vehicle without the proper amount of oil or transmission fluid may damage the engine.
  • Loss of vehicle power: A loss of power may prevent the driver from accelerating into a busy road or onto a highway, increasing the risk of an accident. A power loss may also reduce the driver’s ability to speed up to avoid an accident. Finally, the vehicle may slow down on its own until it comes to a complete stop, increasing the risk of being struck by another vehicle coming up from behind.
  • Increased risk of fire: A fire can injure the vehicle occupants, or cause the driver to lose control and cause an accident. This article explains what you should do if you believe your vehicle is on fire.

The repair

To fix the issue, dealers will need to check the start-stop accumulator end cap and determine if any bolts are missing. If they are, the dealer will replace the end cap at no cost to the owner. GM expects the recall to begin on December 14, 2020.

General Motors ordered to recall 5.9 million cars equipped with Takata airbags

Pleasanton, CA – December, 3 2020 – The National Highway Traffic Safety Administration (NHTSA) has ordered General Motors (NYSE:GM) to recall 5,888,421 pickup trucks and SUVs built with potentially dangerous Takata airbag inflators, which could explode and fling deadly shrapnel into vehicle occupants. The infamous airbag inflators have already killed 27 people and injured at least 250 more, and are part of the largest auto recall in history. The latest installment of the recall – which already encompasses 19 car manufacturers and “tens of millions” of cars – includes the following GM models on the GMT900 platform: 

  • 2007-2014 Cadillac Escalade ESV and EXT SUVs
  • 2007-2014 Chevrolet Avalanche pickups
  • 2007-2014 Chevrolet Silverado 1500 and 2500/3500 pickups
  • 2007-2014 Chevrolet Suburban SUVs
  • 2007-2014 Chevrolet Tahoe SUVs
  • 2007-2014 GMC Sierra 1500 and 2500/3500 pickups
  • 2007-2014 GMC Yukon XL SUVs

Recall summary

The recall concerns the vehicles’ passenger-side airbag inflators. The inflators use ammonium nitrate to generate a small explosion to inflate the airbags. If this volatile chemical is exposed to heat and humidity, it becomes porous. The extra surface area in this microscopic swiss-cheese allows the ammonium nitrate to burn faster, thus causing a much stronger explosion than intended. This explosion can blow up the inflator and send bits of shrapnel flying into vehicle occupants at high speeds, potentially maiming or killing them.

NHTSA first ordered GM to recall the affected cars in 2016. The company had recalled 330,198 vehicles on the GMT900 platform in May 2015, but argued that the rest of vehicles that are now being recalled should be excluded because the airbag defect was “inconsequential.” This argument was rejected by NHTSA on November 23. Despite disagreeing with the decision,  GM said it would not appeal.

‘Almost no data’ to back up claims

NHTSA consulted air-bag chemical expert Harold Blomquist regarding these findings, who rebutted GM’s many claims that unique design features could prevent their inflators from exploding. “GM expended little effort over the last two years to methodically study the claimed features in order to substantiate their effectiveness,” he said in his 75-page review of GM’s petition. As a result, Blomquist said, GM had “almost no data” to back up their claims that their Takata airbags were somehow less dangerous.

Previous Takata airbag recalls

Automakers have been issuing ever-expanding recalls of Takata airbags for seven years, with 100 million inflators recalled worldwide. Volkswagen, BMW and Honda all recalled cars this and past year because of the airbag issue.


GM will replace the Takata airbags with a different model, free of charge. More information about the recall schedule should be released by December 24. 

What to do if you own a recalled vehicle

NHTSA has issued a few broad recommendations for drivers in the Takata recall population:

  1. Don’t have your dealer disable your airbags. “It is much more likely that your airbag will perform properly and protect you in a crash than cause harm,” NHTSA says.
  2. “If you feel uncomfortable continuing to drive your vehicle before it is repaired, you should contact your dealer to see if they will provide a loaner until the repair is completed,” NHTSA says. Dealers and manufacturers aren’t required to provide loaners, but it can’t hurt to ask. 
  3. If you’re offered an interim repair, take it. Some automakers will offer to replace the old Takatas with newer ones, which are safer. “It is an inconvenience to have your vehicle serviced twice and to wait for a final repair,” NHTSA says, “But rejecting an interim replacement air bag is not worth the continued higher risk of injury or even death to you, your family, and your friends while waiting for the final repair.”

Some automakers have advised riders not to sit in the front passenger seat. 

Here is the list of vehicles that NHTSA says should NOT be driven.

General Motors issues another round of recalls for brake assist system

Pleasanton, CA – November 25, 2020 – General Motors (NYSE:GM) has recalled 14,620 vehicles that operate with either 5.3L or 6.2L V8 engines. In each case, the power of the mechanical vacuum pump  – which helps the engine with several key functions, including braking – may decrease. This may negatively affect the brake assist system. The recall includes:

  • 2018  Cadillac Escalade sedans
  • 2018 Chevrolet Silverado 1500 trucks
  • 2018 Chevrolet Tahoe SUVs
  • 2018 GMC Sierra 1500 trucks
  • 2018 GMC Yukon SUVs

Recall summary  

Among other functions, the mechanical vacuum pump provides power to the brake assist system. Due to a design error that was not addressed during a previous recall of the vacuum pump in the power assist brakes last year, essentially “the output” of the pump can drop over time, making the power brake assist system less effective.

There are several factors that alert the driver to the brake assist issue:

  • The brake pedal may vibrate when the driver applies the brakes
  • Braking requires more effort
  • A ticking sound is emitted from the engine compartment when the brakes are applied
  • The driver may see a “Service Brake” message pop up on the dash


If the brake assist is not operating correctly, the driver must press on the brake pedal with more effort and depress it further to be able to stop the vehicle.

This change in braking ability increases the risk of a crash. Drivers may not be able to brake quickly enough to slow or stop the vehicle. GM notes that the problem is more apparent at low speeds when a driver applies soft pressure to the brakes.

The repair

To fix the issue, dealers will need to inspect the Electronic Brake Control Module and reprogram the system. The recall is free of charge and began on November 16.

General Motors recalls SUVs for blocked fuel pump nozzle

Laguna Hills, CA – November 16, 2020 – General Motors (GM) (NYSE: GM) has recalled 2,781 midsize SUVs which may have a blocked fuel pump nozzle that could stall the vehicle. The recall includes:

  • 2020 Buick Enclave
  • 2020 Cadillac XT5 and Cadillac XT6
  • 2020 Chevrolet Traverse
  • 2020 GMC Acadia

and concerns the fuel tank pump module (MODULE – F/TNK F/PMP, #84702674).

Recall summary  

The issue stems from the fuel pump, which supplies the vehicle’s engine with the gasoline it needs to run. A tube inside the fuel pump may be blocked by burrs left over from the manufacturing process. This could keep fuel from getting to the engine, particularly if the gas tank is already running low. If the engine is starved of fuel, the car could unexpectedly stall while driving.


A car that stalls in moving traffic, especially at high speeds, can get hit from behind as other drivers may not have enough time to react. Even if the driver safely gets to the shoulder, they are still at risk of being hit. This raises the risk of injuries or death for everyone involved.

For information on what to do if your car stalls, please see this article.

The repair

Owners will be notified about the recall by mail starting on November 30. GM will replace the fuel pump module for free, but this service is not yet available. In the meantime, owners who are not comfortable driving their recalled car may be eligible for courtesy transportation through their vehicle’s warranty.

General Motors recalls vehicles for contaminated brake booster

Pleasanton, CA – Sept 24, 2020 – General Motors (GM) (NYSE: GM) has recalled 6 different vehicle models which may have a contaminated component in the braking system. This contamination could disrupt sensor communications to the brake booster, making it harder to stop the vehicle and increasing the risk of a crash. The recall includes:

  • 2020-2021 Buick Encore GX subcompact SUVs
  • 2020 Cadillac CT4 and CT5 luxury sedans
  • 2020 Cadillac XT4 compact SUVs
  • 2020 Chevrolet Corvettes
  • 2021 Chevrolet Trailblazer crossovers

Recall summary  

The recall concerns the brake-by-wire system, which uses an electronic brake booster to help stop the car quickly without depending on how hard the driver presses the brake pedal. 

In June, GM launched an investigation after receiving multiple complaints about the strength of the brakes. They discovered that, due to a factory cleaning issue, the connector between the rotor position sensor and the electronic brake control module had been contaminated.

This contamination can disrupt communication between the two parts and disable the electronic brake booster.

Safety tips

Drivers with a failing brake booster may notice that their brakes are difficult to press. They may also notice an increase in the car’s stopping distance. 

Own one of these affected vehicles? It may be wise to keep an eye on the instrument panel, which will display a warning message if the brake booster fails. If this happens, keep the increased stopping distance in mind as you drive.

The repair

Dealers will replace the vehicles electronic brake control module for free. However, this repair is not yet available, as GM is still working on sourcing enough replacement brake boost modules. The company will notify owners when the repair becomes available.

Is your vehicle part of this recall?

Over 3,000 vehicles are part of this GM recall. To see if your car is one of them, use MotorSafety’s free vehicle lookup tool.

General Motors trucks recalled for a software error

Laguna Hills, CA – Dec. 20, 2019 – General Motors LLC is recalling certain 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 vehicles. The Electronic Brake Control Module (EBCM) may have a software error that could disable the Electronic Stability Control (ESC) and Antilock Brake System (ABS).

The potential number of vehicles affected is estimated at 463,995.

The Defect

The affected vehicles have a software defect in the EBCM that will disable the ESC and ABS for a single ignition cycle. In situations where the ABS and ESC are disabled, the vehicle diagnostic’s telltale lamps won’t light up, leaving the driver unaware of the problem. Driving without knowledge of a defective ABS or ESC may increase the risk of a crash. In addition, the lack of warning of a defect puts the vehicles out of compliance with S5.3 of Federal Motor Vehicle Safety Standard 126 and S5.1 of Federal Motor Vehicle Safety Standard 135.

According to General Motors, an estimated one percent of the total vehicles for each model are affected.

Timeline of Events

On November 15, 2019, General Motors’ EBCM supplier, ZF TRW, informed the company that they had found a software error while investigating a related product. On December 5, 2019, General Motors’ Safety and Field Decision Authority decided to call for a noncompliance recall.

The Solution

General Motors will provide dealers with a list of affected vehicles through GM GlobalConnect Recall Reports. General Motors dealers are expected to reflash all affected EBCMs, updating the software and correcting the problem. Moving forward, the software error has been corrected for the 2020 model year.

Because all affected vehicles are the current model and under warranty, General Motors will not have to provide reimbursements. Owners can check to see if their vehicle is being recalled by searching their VIN number at In some cases, courtesy transportation may be provided to affected drivers. Dealers will be notified of the recall December 12, 2019. GM will begin notifying individual owners January 27, 2020.

Cadillac Luxury Sedan Recalled Over Sensor Issue

Laguna Hills, CA – November 5, 2019 – General Motors recently notified dealers that it would have to recall a small population of its Cadillac CT6 luxury sedans due to a problem with their tire pressure sensors.

In all, just 81 CT6 sedans from the 2020 model year will be recalled – 100% of which were identified as having this issue. The company noted that similar vehicles that did not have the accessory wheels installed at their dealers are not included in this recall.

The defect

Specifically, these vehicles – all produced between August 1 and September 9, 2019 – came equipped with specific accessory wheels that had been installed by dealers, but which do no meet Federal Motor Vehicle Safety Standard rules related to tire pressure monitoring systems.

This is because their sensors do not use the proper wireless radio frequency to communicate with the vehicle’s computer, and as a consequence, the system may not be able to properly alert drivers – via a warning light on the dashboard – that tire pressure has dropped to potentially dangerous low levels.

The problem at the heart of the issue is that incorrect part numbers for the tire pressure sensors were put into GM’s ordering system.

Ideally, the automatic system would turn on the warning light after 18 minutes of driving at least 28 miles per hour on tires with low pressure, but because of the mismatched radio frequency, this would not occur.

As a result, drivers may not know of the risks they face unless they manually check their tire pressure before or after a trip. Low pressure can have a detrimental effect on vehicle handling or lead to tire failure, both of which would increase the risk of an accident.

Timeline of events

In September, General Motors received a report about the issue through its Speak Up for Safety program that the wrong tire pressure sensors had been installed on the affected CT6 sedans with specific accessory wheels.

On September 24, the company opened an investigation into the issue, consulting with subject-matter experts and the company’s regulatory engineers.

The GM Open Investigation Review board looked at the findings of this examination on Oct. 7 and recommended that the company issue a recall.

Two days later, the GM Safety Field Action Decision Authority followed through on that recommendation.

The solution

Upon receiving their recall notices, owners should take their affected CT6 sedans to a certified GM dealer, where all four tire pressure sensors will be replaced with proper parts that use the right wireless frequency to communicate with the vehicle.

Given that these are all 2020 model year vehicles, the repairs are covered by warranty and no reimbursement will be offered.

The investigation also found that the incorrect part number that led to the wrong sensors being installed was corrected within GM’s ordering system on September 11. This means that all accessory kits shipped to dealers after that date had the correct sensors.

Dealers were notified of the recall on October 15, and owner notification dates are yet to be decided.

General Motors Recalls Various Vehicles Due to Vacuum Pump

December 2, 2021 Update – GM has remedied 2,588,566 vehicles with the issue of vacuum pump issues in the 2018 GMC Yukon among others.  GM has deemed 21,474 vehicles including the 2018 Chevrolet Silverado unreachable with an additional 207 vehicles being removed from the vacuum pump recall.

Laguna Hills, CA – September 17, 2019 – The possibility that vacuum pumps in various General Motors vehicles may vary in performance has caused the company to conduct a recall of General Motors vehicles due to vacuum pump issues.

According to the “Frequently Asked Questions” document provided by the manufacturer, General Motors has decided that a defect, which relates to motor vehicle safety exists in the following vehicles:

  • 2014 – 2018 Cadillac Escalade
  • 2014 – 2018 Chevrolet Silverado
  • 2014 – 2018 Chevrolet Suburban
  • 2014 – 2018 Chevrolet Tahoe
  • 2014 – 2018 GMC Sierra
  • 2014 – 2018 GMC Yukon

The defect

Within the GM vehicles that contain the mechanical vacuum pump defect, the engine-mounted output may decrease over time, diminishing the power brake assist and therefore increasing the distance required to stop the vehicle.

Ultimately, this leads to a greater chance of an accident and adds to other risks that Chevrolet vehicles have presented during collision events.

According to documents filed with the National Highway Traffic Safety Administration, the number of vehicles that potentially contain the defect is greater than 3,450,000, with GM estimating that 2 percent of the autos in that total are almost certainly affected by this issue.

The following vehicles make up the group possibly saddled with the vacuum pump problem:

  • Cadillac Escalade 2015 – 2017
  • Chevrolet Silverado 1500 2014 – 2018
  • Chevrolet Suburban 2015 – 2018
  • Chevrolet Tahoe 2015 – 2018
  • GMC Sierra 1500 2014 – 2018
  • GMC Yukon 2015 – 2018

There are certain symptoms that drivers may experience if their car is among those affected by the vacuum pump defect. For instance, they may feel a vibration in the brake pedal or experience a change in the amount of pressure required to depress the brake.

Other possible signs of the problem include a ticking noise coming from within the engine compartment and unintentional activation of the secondary hydraulic brake assist system, according to GM.

Finally, the manufacturer noted that if the vacuum level drops to a level below 10 kPA, a “Service Brake Assist” message will appear in the Driver Information Center within five minutes.

GM has determined that while the defect may potentially increase the possibility of collision, all of these vehicles are otherwise safe to drive before undergoing repair of the vacuum pump.

Timeline of events

According to a chronology provided by GM, the NHTSA opened a preliminary investigation into the subject in November 2018, at which point the manufacturer also began an internal investigation of the same issue.

In December, after reviewing the results of both investigations, GM’s Safety & Field Action Decision Authority decided to extend the warranty on vacuum pumps for all the vehicles listed above.

Then, in July 2019, GM received results of the additional investigation into the subject by the NHTSA, which prompted yet another internal inquiry on the part of the manufacturer.

This final study concluded on August 29, 2019, when GM decided to conduct an official recall on the automobiles to provide them with new software calibration.

Dealers were notified of the recall in early September 2019, with GM planning to send direct notifications to affected drivers in the near future.

The solution

Vehicles that contain the defect can be brought to a local dealership, where the dealer will reprogram the electronic brake control module with a new calibration that corrects the problem, should the vacuum assist become depleted.

As with the potentially dangerous Takata airbag issue reported in early 2021, drivers with a vehicle involved in the recall will be notified by mail. There will be no cost to vehicle owners for repair or repair. Check your car’s recall status using MotorSafety’s free vehicle recall lookup tool.

GM Recalls 2016 – 2018 Cadillac CTS and ATS, Chevy Camaro and Corvette for Power Steering Issue

Laguna Hills, CA – March 28, 2019 – General Motors is recalling certain 2016 – 2018 Cadillac CTS and 2017 Cadillac ATS, Chevrolet Camaro and Chevrolet Corvette vehicles because the power steering assist system may fail, increasing the risk of a crash. As many as 26,772 vehicles may be affected.

The defect

According to the National Highway Traffic Safety Administration report on this problem, the affected vehicles may experience a loss of electric power steering assist while driving. This would demand more effort in steering, especially at lower speeds, with a potentially greater risk of a crash.

Timeline of events

GM launched an investigation September 18, 2018 into loss of power steering assist in the 2017 Chevrolet Camaro.

Between September 19 and late October, GM’s safety investigator, with help from engineering experts, analyzed vehicle owner questionnaires, customer complaints, legal claims, and warranty data to assess the number of cases in the field and to identify common root causes.

An intermittent electrical loss within the torque-sensor printed circuit board was found in about 80 percent of the cases reviewed. The same issue was found in two Corvette steering gear assemblies. GM then expanded its investigation, discovering that the Cadillac CTS and ATS were also at risk.

Between November and mid-December, field analysis revealed spikes in warranty rates between June and September 2016, and a three-day window in February 2017.

Between mid-December and late January 2019, GM worked with its supplier to identify the problematic circuit boards and VIN numbers of affected vehicles.

Following an open investigation review, GM’s Safety Field Action Decision Authority decided  January 31 to conduct a safety recall.

The solution

The recall will begin March 2019. GM will notify owners, and dealers will replace the power steering gear assembly, free of charge. Owners will receive a second notice when the remedy becomes available. GM’s number for this recall is N182182760.

General Motors LLC Recalls 2019 Cadillac CT6 Vehicles for Turn Signal Defect

Laguna Hills, CA – March 25, 2019 – General Motors LLC is recalling certain 2019 Cadillac CT6 vehicles because rotating the steering wheel does not prevent the turn signals from flashing.

If the turn signals do not automatically stop, the driver may neglect to turn them off manually, misleading other drivers and pedestrians, which could increase the risk of a crash. Up to five vehicles may be affected by this issue.

The defect

According to the National Highway Traffic Safety Administration Report on this issue, rotation of the steering wheel will not automatically cancel the turn-signals from flashing after a turn is made.

Although this action can still be done manually, the driver may fail to respond when turn signals do not deactivate automatically, leaving the signals flashing for some time afterwards.

When this happens, a false turn signal may misinform pedestrians and other drivers, which could potentially lead to an accident or crash.

Timeline of events

General Motors issued its initial report on this problem on February 21, 2019. GM decided that certain 2019 Cadillac CT6 vehicles failed to conform to Federal Motor Vehicle Safety Standard 108, “Lamps, reflective devices, and associated equipment.”

The automaker then announced a recall beginning March 11.

The solution

Cadillac dealers will replace the turn signal switch at no charge. Dealers are to service all vehicles subject to this recall at no cost to customers, regardless of mileage, age of vehicle or ownership, from this time forward.

In addition, all affected vehicles currently in the dealer’s possession that have not yet been sold are also subject to the recall.

The vehicles must be inspected and repaired before they are delivered to customers, dealer-traded, released to auction, used for demonstration or any other purpose.

Courtesy transportation is available for U.S. customers whose vehicles are involved in this recall and within the coverage period for the warranty associated with this action.

The NHTSA Campaign Number for this recall is 19V117.
