General Motors (GM) will be providing owners of certain 2016-2017 Chevrolet, Cadillac and GMC trucks additional warranty coverage because of a problem that could affect the fuel injectors in their engines. The trucks receiving additional warranty are equipped with 5.3L or 6.2L engines.

Vehicles manufactured with these defective fuel injectors include:
2016-2017 Cadillac Escalade
2016-2017 Cadillac Escalade ESV
2016-2017 Chevrolet Silverado
2016-2017 Chevrolet Suburban

** GM will notify customers if this special warranty coverage is on their vehicle.**

The special coverage will extend the warranty of the above vehicles, for a period of 10 years or 150,000 miles (240,000km), whichever occurs first, from the date the vehicle was originally purchased, regardless of ownership. This special coverage only applies to vehicles in these states: California, Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington.

According to documents released by GM, “Under certain circumstances, one or more of the vehicle’s fuel injectors may deliver an improper amount of fuel to the engine. If this happens, the Malfunction Indicator Lamp (the Check Engine Light) will illuminate to warn the driver there is a problem. The engine will begin to run rough and will eventually stall. Diagnostic trouble codes, including P0300-P0308 or DTC P050D, will be set.

Other symptoms of a bad or dirty fuel injector include: The vehicle is hard to start and idles rough; Poor performance and increased fuel consumption; and an engine knock or detonation that could lead to complete engine failure.

The rear-wheel driveshaft assemblies on certain 2021 Cadillac, 2021 Chevrolet and 2021 GMC SUV trucks could fail and cause an increased chance of an accident. GM will be contacting owners and asking them to return to their dealership for repairs.

In October 2021, GM’s supplier of rear-wheel drive-shaft assemblies informed them that certain assemblies shipped to GM’s Arlington, Texas plant may have been manufactured improperly. GM opened an investigation and found that the suspect components could deform over time and result in drive shaft seizures.

According to the defect report, the rear-wheel drive-shaft assemblies may have been manufactured with recirculating balls that were not properly heat treated. The recirculating balls could deform over time, resulting in noise and vibration. If the vehicle continues to be driven, the affected joint in the drive shaft assembly could seize and the vehicle could lose propulsion.

Vehicles manufactured with these defective driveshafts assemblies include:
2021 Cadillac Escalade
2021 Cadillac Escalade ESV
2021 Chevrolet Suburban
2021 Chevrolet Tahoe
2021 GMC Yukon
2021 GMC Yukon XL

The supplier’s equipment failure was corrected on June 4, 2021 and components produced after that time were properly heat treated. Vehicles produced after October 4, 2021, were equipped with drive shaft assemblies containing components that were produced outside of the suspect window.

Owners will be asked to return to their dealers to have the left and/or right rear driveshaft assemblies replaced. GM’s number for this recall is N212351030, N212351031 and N212351032. The NHTSA campaign number is 22V-036. Customer interim notifications are estimated to be sent out on March 14, 2022.

General Motors has decided that a defect relating to vehicle safety exists in certain 2021-2022 Chevrolet Silverado 2500/3500 and 2021-2022 GMC Sierra 2500/3500 trucks.

GM first became aware of the problem in September 2021 when two 2021 GMC Sierra 2500 vehicles experienced under hood fires at the assembly plant. Both vehicles were parked outside awaiting shipment and had been exposed to heavy rainfall the day before. Using X-ray and CT scans on the vehicles showed a gap between the bolt head and brake pressure modulator valve (BPMV), indicating that the assembly had not been properly sealed to prevent water intrusion. Both vehicles had been subject to temporary production process changes that involved offline replacement of the electronic brake control module (EBCM), which is a sub-assembly of the BPMV. Analysis of the vehicles also found that the fire started in this area.

According to the defect report, bolts attaching the BPMV may have not been properly tightened, failing to create the seal between two sub-assemblies that is intended to prevent water intrusion. If water becomes trapped in the BPMV, it could result in a short circuit, which could lead to an under hood fire.

Owners of these trucks are advised to park outside and away from other structures until the recall repair is completed. Dealers will correct the problem by replacing the BPMV assembly.. GM’s number for this recall is N212349181 and the NHTSA campaign number is 21V-758.

In July 2021 General Motors (GM) opened an investigation into fuel pump failures after a review of warranty data from certain 2021 GM full size SUVs. The data showed that there was a higher than expected rate of fuel pump control modules replaced for vehicles built within certain months. As part of the investigation, GM looked at the returned parts replaced in warranty claims and found the condition was caused by a manufacturing issue at the Tier 3 supplier.

According to the defect report, certain 2021 Cadillac, Chevrolet and GMC full size SUVs may have been manufactured with fuel pump power control modules which contain a defect that can cause the fuel pump to fail or operate intermittently. When this happens, fuel flow to the engine will be interrupted and the vehicle could unexpectedly stall.

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

Owners receiving notices will be asked to return to their dealers to have the fuel pump power control module replaced. GM’s number for this recall is N212332040 and the NHTSA campaign number is 21V-739.

In December 2020, Fox Factory received its first reports that certain GM vehicles fitted with Tuscany lift kits could experienced partial or complete wheel separation while in operation. Fox began reviewing field data and started a safety investigation to assess the failure mode, the failure rate and potential causes of the problem. By September 2021 Fox identified 28 warranty claims and field or service reports potentially relating to this issue and decided to initiate a voluntary safety recall.

According to the defect report, “Accelerated wear on the vehicle OEM installed ball joint in the front upper control arm can result in premature ball joint failure and a front wheel separation while the vehicle is in motion .”

Failure of a ball joint in a front upper control arm may be preceded by noise and / or a feeling of clicking in the steering, abnormal front tire wear and abnormal steering.

The Vehicles Affected Include:
2019-2021 Chevrolet Silverado 1500
2019-2021 GMC Sierra 1500

New Tuscany front upper control arms will be installed in place of the GM front upper control arms. The fix will include upgraded front upper control arms with stronger and less corrosion sceptible ball joints. NHTSA Campaign Number: 21V718.

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.

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.

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.
