Chevrolet Trailblazer Recall Lawsuit | 2026 Latest Updates

General Motors has issued eight separate safety and emissions recalls for the Chevrolet Trailblazer since 2020, plus related campaigns on the Buick Encore GX and Buick Envista. They range from a mislabeled tire to a fracture-prone jack. Other campaigns address a brake-boost sensor fault, a wrong catalytic converter, an emissions code that would not clear, an ignition-timing fault, and a camera that can go blank. GM’s fix ranges from hardware to a free reprogram. Model years from 2020 through 2026 are involved, so not every Trailblazer is affected by every campaign. The newest recall, covering 306,511 rearview cameras, remains open. Owners should check their vehicle identification number at nhtsa.gov to see which recalls apply.

Latest Chevrolet Trailblazer Recall Updates

August 20, 2026: GM Recalls the Rearview Camera

General Motors placed 2024-2026 Chevrolet Trailblazer, 2025 Chevy Trax, and related Buick Encore GX units on stop-sale after finding some rearview cameras could show a blank or distorted image [1]. The camera-housing adhesive had weakened during assembly. The recall, GM campaign A262554900, covers 306,511 vehicles in the United States. Dealers will inspect and replace the camera at no charge to the owner.

March 9, 2026: A Federal Engine-Defect Lawsuit Is Filed

GM Authority reported that plaintiffs Samantha and Donna Cook filed a proposed class action, Cook v. General Motors LLC, in the U.S. District Court for the District of Delaware [2]. The suit targets the 1.2L turbo engine. The engine is used in 2024-and-newer Chevrolet Trailblazer, Chevy Trax, Buick Encore GX and Buick Envista models. Plaintiffs describe connecting-rod failures, oil leaks and a fire risk, and the case remained in early discovery.

June 23, 2024: GM Recalls 2024 Models for an Ignition-Timing Defect

General Motors announced recall A242435780, a voluntary emissions recall for 2024 Chevy Trax, Trailblazer and Buick Envista units with the turbocharged 1.2L I3 engine [3]. The engine control module could mishandle ignition timing after an Auto Stop/Start event. A resulting engine knock could cause damage if the vehicle kept running, and the check-engine light might illuminate. GM technicians inspect and reprogram the module in about 30 minutes at no charge.

March 17, 2024: An Earlier Engine Control Module Recall Is Reported

GM Authority reported that General Motors had opened recall A222379711 for 2021-2023 Chevy Trailblazer units, plus some 2020-2023 Buick Encore GX, whose engine control module might not clear diagnostic code P0521 [4]. An uncleared code can cause a Trailblazer to fail an emissions inspection, and the check-engine light may stay lit. Dealers reprogram the module free of charge. The affected count was not published at the time.

February 16, 2023: A Catalytic Converter Recall Begins

GM placed a stop-delivery on 2023 Chevy Trailblazer and Buick Encore GX units powered by the 1.2L turbo-three engine, recall A232398131 [5]. Some of these units left the factory with an incorrect catalytic converter. The wrong part cannot fully process exhaust gases and can fail an emissions test. GM estimated the recall affects 1,500 vehicles, with about 32 units actually equipped with the incorrect part. Dealers replace it free of charge.

June 10, 2021: GM Recalls a Fracture-Prone Emergency Jack

General Motors placed 2020-2022 Buick Encore GX and 2021-2022 Chevrolet Trailblazer units on stop-delivery under NHTSA campaign 21V440 [6]. The recall followed a finding that the emergency jack could fracture and fail to support the vehicle if mispositioned. If the jack fractures while under load, the vehicle could collapse and injure someone nearby. The recall covers 135,400 vehicles. GM mailed interim owner letters July 26, 2021, with a second letter once replacement jacks became available.

December 9, 2020: NHTSA Opens a Brake-Boost Sensor Recall

NHTSA campaign 20V588000 began after General Motors found that sensor contamination in the electronic brake boost system could interrupt communication between the sensor and the brake booster on some 2021 Chevrolet Trailblazer units [7]. The same campaign also covers some 2020 Chevrolet Corvette, Cadillac CT4, CT5 and XT4, and 2020-2021 Buick Encore GX models. Losing brake-boost assist means extra pedal force is needed to stop. Dealers replace the module free of charge.

October 1, 2020: GM Opens a Seat-Bolt Recall

NHTSA campaign 20V537000 began after General Motors found a problem on some 2021 Chevrolet Trailblazer and 2020 Buick Encore GX units [8]. The rear attachment bolts of one or both front seats may not have been installed. An occupied front seat missing a bolt could shift during a crash. That raises the risk of injury. The recall affects 105 vehicles. Dealers inspect both front seats and install the missing bolts at no cost.

July 1, 2020: A Tire Certification Label Recall Begins

The same NHTSA record cited above for the brake-boost recall, campaign 20V588000, also covers a separate campaign, 20V295000 (GM A202304070): some 2021 Chevrolet Trailblazer units with optional 17-inch tires had a certification label missing the required tire-size and cold-pressure information. Without that information, drivers could overinflate or underinflate their tires and raise the risk of a crash. GM mailed owners corrected labels to apply themselves, free of charge.

Which Chevrolet Trailblazers Are Affected?

Eight separate GM recalls affect the following Chevrolet Trailblazer and related Buick model years, listed by campaign:

• Tire certification label (NHTSA 20V295): 2021 Chevrolet Trailblazer with optional 17-inch sport terrain tires.
• Seat bolts (NHTSA 20V537): 2021 Chevrolet Trailblazer and 2020 Buick Encore GX.
• Brake-boost sensor (NHTSA 20V588): 2021 Chevrolet Trailblazer, plus 2020-2021 Buick Encore GX and other GM models.
• Emergency jack (NHTSA 21V440): 2021-2022 Chevrolet Trailblazer and 2020-2022 Buick Encore GX.
• Catalytic converter (GM A232398131): 2023 Chevrolet Trailblazer and 2023 Buick Encore GX with the 1.2L turbo engine.
• Engine control module (GM A222379711): 2021-2023 Chevrolet Trailblazer and some 2020-2023 Buick Encore GX.
• Emissions and ignition timing (GM A242435780): 2024 Chevrolet Trailblazer, Chevy Trax, and Buick Envista with the 1.2L turbo engine.
• Rearview camera (NHTSA 26V539): newer Trailblazer, Trax, Encore GX and Envista model years through 2026.

Owners can confirm whether a specific vehicle is included in any of these campaigns by entering its 17-character VIN at nhtsa.gov/recalls [9].

Why Were the Chevrolet Trailblazers Recalled?

General Motors recalled the Chevrolet Trailblazer eight separate times since 2020 for eight distinct problems. These include a mislabeled tire certification sticker, missing seat-attachment bolts, and a brake-boost sensor fault. The middle problems are a jack that could fracture under load and an incorrectly installed catalytic converter. The final two are an engine control module that would not clear a diagnostic code and an ignition-timing software fault. The eighth problem is a rearview-camera assembly with a weakened adhesive bond that can display a distorted or blank image. The catalytic converter, engine control module, and ignition-timing recalls all involve the Trailblazer’s turbocharged 1.2L I3 engine. The catalytic-converter recall is different: it is not a software problem but a physical part installed incorrectly at the factory during assembly.

Reported Incidents, Injuries, or Illnesses

None of the eight recall records states a specific number of injury, crash, or fire reports tied to these campaigns. GM’s bulletins describe the underlying safety risk rather than a count of incidents that have actually occurred. For the seat-bolt and jack recalls, GM’s own notices describe a crash-related injury risk if the defect is present and the vehicle is involved in a collision. For the catalytic converter and emissions-related recalls, GM has not indicated any specific hazard beyond a failed emissions test and possible inconvenience. A distorted or blank camera screen reduces visibility when backing up, which raises the risk of a collision. Reports of a problem are not proof that a defect caused a specific crash, injury, or fire in every case.

What Should Consumers Do?

Follow these steps if you own or lease a Chevrolet Trailblazer, Buick Encore GX, or Buick Envista covered by one of these recalls:

1. Check your VIN online to see which campaigns, if any, apply to your vehicle.
2. Wait for GM’s mailed notification, or contact your Chevrolet or Buick dealer directly to ask about an open recall.
3. Schedule a free inspection and repair.
4. Call Chevrolet Customer Service at 1-800-630-2438 or 1-800-222-1020, or the NHTSA Vehicle Safety Hotline at 1-888-327-4236, with questions about a specific recall.
5. Keep records of your repair confirmation and any correspondence with GM in case a question comes up later.

Legal Options

A recall does not automatically establish liability or eligibility for compensation. Separately from the recalls above, Cook v. General Motors LLC, a proposed class action, is pending in Delaware federal court over the same 1.2L turbo I3 engine described above. As of the case’s early March 2026 reporting, no class had been certified and no settlement or verdict had been reported.

Filing Deadlines

Deadlines to bring a legal claim over a vehicle defect come from state law, not from GM or NHTSA. How much time you have depends on where you live and when the defect and any resulting harm became known. Some states start the clock at diagnosis or discovery rather than the original recall date. Missing a deadline can end a claim, so anyone considering the Cook v. General Motors litigation or another claim should speak with a lawyer promptly.

Frequently Asked Questions

How Do I Know If My Chevrolet Trailblazer Has a Recall?

You can find out by entering your Chevrolet Trailblazer’s 17-character VIN at nhtsa.gov/recalls. That tool shows any unrepaired safety recall filed against your VIN in the past 15 years.

Why Do I See Two Different GM Numbers for the Chevrolet Trailblazer Jack Recall?

You may see two different GM numbers for your Chevrolet Trailblazer’s jack recall. General Motors’ own bulletin lists it as A212335471, while NHTSA’s public database lists the same NHTSA campaign 21V440 as A212335470. Either number works when you call for service.

When Did NHTSA First Learn About the Chevrolet Trailblazer Seat-Bolt Recall?

NHTSA first learned about the Chevrolet Trailblazer seat-bolt recall on March 9, 2020. That is when it received General Motors’ defect report, roughly seven months before the recall itself officially began on October 1, 2020.

Are Buick Encore GX Vehicles Also Affected by These Recalls?

Yes, Buick Encore GX vehicles are also affected by six of these eight recalls. They share the seat-bolt, brake-boost, jack, catalytic converter, engine control module, and rearview camera campaigns with the Trailblazer. Only the tire-label and the 2024 emissions recalls skip the Encore GX.

Will GM Contact Me Directly About a Trailblazer Recall?

Yes, GM will contact you directly about a Trailblazer recall. It mails written notice once it has your current address, as it did for the 2021 jack recall in July. You do not have to wait for that letter before checking your VIN online.

What Is Buick’s Customer Service Number for These Recalls?

Buick’s customer service number for these recalls is 1-800-521-7300, and that line covers only the Encore GX campaigns. Chevrolet Trailblazer owners should use the numbers already listed in the consumer steps above instead.
