reported issues, recalls & what to inspect
This report uses official federal safety records plus VeroRoad’s vehicle × tool evidence. It is a screening tool, not a reliability grade or prediction that your specific car will fail.
56 unique complaint records6 recall campaigns returned0 complaint rows with usable mileage7 local vehicle/tool evidence rows
NHTSA complaints are consumer-submitted allegations, not verified failures. Raw complaint totals are not failure rates because vehicle sales/exposure are not normalized here. A recall is an official safety campaign, but your VIN may or may not be included.

21V115000TIRES
General Motors LLC (GM) is recalling certain 2020 Buick Enclave, Cadillac XT4, XT5, Escalade, Escalade ESV, Chevrolet Suburban, Tahoe, Traverse, GMC Yukon, Yukon XL, 2018-2021 Chevrolet Express, GMC Savana, 2019-2020 Chevrolet Blazer, Silverado 1500, GMC Acadia, Sierra 1500, and certain Continental tires sold to the aftermarket for various model year 2018-2021 vehicles. The affected tires were cured for too long during production.
Why it matters: Over cured tires may develop a break in the sidewall resulting in sudden air loss or a belt edge separation which could lead to a tread/belt loss. Either condition can cause a loss of vehicle control, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will inspect the tires, replacing them as necessary, free of charge. The recall began March 22, 2021. Owners may contact GMC customer service at 1-888-988-7267, Buick customer service at 1-866-608-8080, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006. GM's number for this recall is N212329050.

General Motors LLC (GM) is recalling certain 2020 Buick Enclave, Cadillac XT5, Cadillac XT6, Chevrolet Traverse, and GMC Acadia vehicles. The fuel pump's jet nozzle may have a plastic burr remaining from the manufacturing process, possibly causing a blocked nozzle and an insufficient fuel supply to the engine.
Why it matters: Insufficient fuel supply can result in an engine stall without warning, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will replace the fuel pump module. The recall began November 16, 2020. Owners may contact GMC customer service at 1-888-988-7267, Buick Customer service at 1-866-608-8080, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006.

Reported 15/10/2020 · Verify exact VIN applicability.20V684000TIRES
General Motors LLC (GM) is recalling certain 2020 Buick Enclave, Cadillac XT5, GMC Acadia and Chevrolet Traverse vehicles and 2020-2021 Chevrolet Silverado 1500, GMC Sierra 1500 vehicles. The vehicles may have been manufactured with Continental tires that were overcured.
Why it matters: Overcured tires may experience a carcass break in the sidewall resulting in a sudden air loss or could develop a belt edge separation which could lead to partial or full tread/belt loss. Either condition increases the risk of a crash.
Remedy: GM will notify owners, and dealers will inspect vehicles and replace tires that have DOT number and production mold number combinations identified by Continental, free of charge. The recall began December 17, 2020. Owners may contact GMC customer service at 1-888-988-7267, Buick customer service at 1-866-608-8080, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006.

Reported 05/11/2020 · Verify exact VIN applicability.20V446000AIR BAGS:SIDE/WINDOW:CURTAIN:INFLATOR
General Motors, LLC. (GM) is recalling certain 2020 Buick Enclave, Cadillac XT5 and XT6, Chevrolet Blazer, Silverado 1500, 2500 and 3500 and Traverse and GMC Acadia and Sierra 1500, 2500 and 3500 vehicles. The diffuser component of the Roof-Rail Air Bag (RRAB) inflator may not have been properly crimped to the inflator and could separate from the inflator during air bag deployment.
Why it matters: If the diffuser separates from the inflator during deployment, RRAB performance may be degraded, increasing the risk of injury in a crash.
Remedy: GM will notify owners, and dealers will replace the suspect RRAB modules, free of charge. The recall began September 3, 2020. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-333-4223, or Buick customer service at 1-800-521-7300. GM's number for this recall is N202305380.

What I would inspect before money changes hands
The highest reported component groups are converted into inspection tasks. They are not diagnoses.
Engine & powertrain
15 owner complaints in the leading component signal intersect this system.
- Cold-start behavior and idle quality
- Acceleration under light and moderate load
- Current, pending and permanent DTCs
- Freeze-frame and fuel/engine live data where available
UNKNOWN OR OTHER
12 owner complaints in the leading component signal intersect this system.
- Inspect the affected system carefully
- Scan all modules before clearing codes
- Review service history and previous repair records
Electrical & 12V system
9 owner complaints in the leading component signal intersect this system.
- 12V resting and charging voltage
- Module communication scan
- Battery age and terminal condition
- Unexpected warning lights or intermittent electrical behavior
Brakes & ABS
4 owner complaints in the leading component signal intersect this system.
- ABS/ESC warning lights
- Wheel-speed live data if a warning is present
- Brake pedal feel and parking-brake operation
- Pad/rotor condition and uneven wear
SRS & restraints
3 owner complaints in the leading component signal intersect this system.
- SRS warning lamp self-test
- SRS module codes
- Seat-belt latch/retractor operation
- Recall completion for restraint campaigns
SCAN INTEGRITY CHECK
Make it harder for a recently cleared warning light to fool you.
A clean dashboard is not the same as a clean scan. Readiness monitors, pending codes and permanent codes provide useful context during a pre-purchase inspection.
- Run a full-system scan before clearing anything
- Read current, pending and permanent powertrain codes
- Check readiness monitors; multiple “Not Ready” monitors can be consistent with a recently cleared ECU or disconnected battery
- Save freeze-frame data for any stored emissions/powertrain fault
- Scan ABS, SRS, transmission and body modules when the tool supports them
- Check 12V battery / charging condition because low voltage can create misleading module faults
TSBs & MANUFACTURER COMMUNICATIONS
Look beyond recalls.
Manufacturers submit service bulletins, warranty extensions, repair instructions and other communications to NHTSA. These documents can reveal service procedures and known conditions that are not necessarily safety recalls.
