Configuration applicability

Unresolved · not yet pinned

This model year was built in 4 reviewed configurations (6.2L 4-Wheel Drive; 6.2L Rear-Wheel Drive; 5.3L 4-Wheel Drive; 5.3L Rear-Wheel Drive); configuration-scoped findings can differ between them.

To verify: Enter the VIN, or read the engine/drivetrain from the door-jamb label or window sticker, to pin the exact configuration.

Ownership headache outlook

A responsible candidate scenario cannot be calculated until the missing evidence dimensions are resolved.

What each horizon reaches

1 yrAbout 12,000 mi — before every named onset band.
3 yr (yours)About 36,000 mi — before every named onset band.
5 yrAbout 60,000 mi — before every named onset band.

12,000 annual miles · 3-year ownership horizon · Service history is unknown unless verified by the buyer. These are observed report bands, not failure probabilities.

Ownership-headache outlook: observed onset bands for each named issue.
Issue	Severity	Onset p25	Median	Onset p75	Relation to your window
Service Brakes, Hydraulic:Power Assist:Vacuum safety campaign	High severity	72,000 mi	72,000 mi	72,000 mi	Onset band is beyond your window

Why this answer

1Insufficient evidence: One or more named issues lacks the minimum usable evidence.

Conditions to clear first

official recall record

High severity

Whole generationSingle sourceEvidence: Limited confidence

The cited record is bound to model year 2018; no broader incidence claim is made.

Symptom: General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles.
Why it matters: The official record describes a potential crash, fire, injury, or loss-of-control consequence.

Observed complaint mileage band; not an incidence probability

Reported onset roughly 72,000–72,000 mi (median 72,000 mi).

Onset band is beyond your window.

Based on 1 usable report (4 censored). Complaint mileage is an observed report band, not a population incidence estimate.

What to inspect

Check the VIN for open NHTSA actions, then ask the inspector to test the named system and document the result.

Pro check: Independent pre-purchase inspection.

Mitigation

Verify the campaign status by VIN and retain the completion receipt if the remedy was performed.

Verified remedy: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192268490.

“General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time. As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.

What would change this answer

verified remedy

A newly verified completed remedy with configuration-specific eligibility for Service Brakes, Hydraulic:Power Assist:Vacuum safety campaign could improve the recommendation.

contradictory source

A reviewed official or independent source that materially contradicts the claims for Service Brakes, Hydraulic:Power Assist:Vacuum safety campaign would force confidence and verdict review.

clm_chevrolet-tahoe-2018-recall-recall-19v645000-obs-5378

changed applicability

Reviewed evidence that includes or excludes a different year, engine, drivetrain, trim, or VIN population would change which issues apply.

lost exposure eligibility

A verified production denominator and eligible time-at-risk cohort are required before normalized comparative year guidance can strengthen.

clm_chevrolet-tahoe-2018-recall-recall-19v645000-obs-5378

Applied assumptions

· 12,000 annual miles
· 3-year ownership horizon
· Service history is unknown unless verified by the buyer.

Sharpen it further

Add mileage — it places the onset bands against your ownership window.
Add the asking price — it weighs the findings against what you would pay.
Set your annual miles — assumed 12,000; it sizes the window.
Choose a horizon — assumed 3 years; it sets the window length.

What we could not verify

Every dimension is listed — including the ones we do not have — each with the concrete next step to close it.

ConfigurationPartial
This model year was built in 4 reviewed configurations (6.2L 4-Wheel Drive; 6.2L Rear-Wheel Drive; 5.3L 4-Wheel Drive; 5.3L Rear-Wheel Drive); configuration-scoped findings can differ between them.
Next: Enter the VIN, or read the engine/drivetrain from the door-jamb label or window sticker, to pin the exact configuration.
VIN recall & historyNot verified
A VIN recall check was not handed to this page, so recall status and title/odometer history for this exact car are unchecked.
Next: Run this VIN on NHTSA’s recall lookup and request a title/history report to confirm open recalls and past events.
Repair costNot verified
No sourced repair-cost range is available for the named issues in this release.
Next: Get a written repair estimate for the named issue from an independent shop before you negotiate.
Market price contextNot verified
No asking price was entered and no licensed market-value feed is integrated, so price fairness is not assessed.
Next: Compare the asking price against recent local listings for the same year and configuration.
Onset evidencePartial
Onset bands rest on a limited number of usable reports; treat the band edges as approximate.
Next: Weigh the onset band as a reported-onset range, not a failure probability, and confirm condition by inspection.
