General Motors LLC (GM) is recalling certain 2018 Cadillac Escalade, Chevrolet Silverado 1500 and Tahoe, GMC Sierra 1500 and Yukon vehicles equipped with either a 5

A decrease in brake assist can increase the brake pedal effort and distance required to stop the vehicle, increasing the risk of a crash.

Fix: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began November 11, 2020. Owners may contact GM customer service at 1-866-522-9559, Cadillac customer service at 1-800-458-8006 or Chevrolet customer service at 1-800-630-2438. GM's number for this recall is N202300860.

The failure pattern owners describe

Buyer takeaway: The 2018 Tahoe has reported vacuum pump failures and brake assist loss that can disable braking power—a critical safety issue. Multiple owners report symptoms matching GM recalls but find their VINs excluded from coverage, leaving them paying out of pocket for repairs or driving unsafe vehicles.

The 2018 Tahoe brake complaints center on a failing vacuum pump system that compromises brake assist. Owners describe a hard brake pedal that requires heavy foot pressure, extended stopping distances, and illuminated brake warning lights. One owner experienced total brake failure on I-95 and had to use the emergency brake twice to stop. Another reported brakes skipping during normal stops and reversing. When the vacuum pump seizes or deteriorates, brake assist drops, and the system responds by lighting the dashboard with "service brake assist" warnings.

Many owners link their symptoms to GM's Special Coverage Adjustment N182202780 (brake assist loss) and NHTSA Campaign 19V761000, yet dealerships tell them their VINs are not included in those recalls—despite identical failure patterns. One owner took the vehicle to the dealer three times without resolution. A separate failure mode involves unintended brake pulling (left or right) paired with a spurious "trailer brake system failure" message on vehicles that have never towed. Another complaint describes a vacuum leak that causes a rock-hard brake pedal after overnight parking. Repair costs and parts information are sparse in these narratives; one owner's vacuum pump was replaced, but several others report the dealer refused to diagnose or repair due to VIN exclusions from recall lists.

Failure modes owners describe

Vacuum pump failure with reduced brake assist

The brake vacuum pump deteriorates or seizes, reducing vacuum pressure in the brake system. This causes brake assist to decrease, requiring significantly harder pedal pressure to stop the vehicle and extending braking distance—a serious safety hazard. Owners report hard brake pedal feel, extended stopping distance, and illuminated brake warning lights.

When: 72,000 miles noted in one complaint; no consistent mileage pattern across narratives

Symptoms owners cite: Brake pedal requires hard pressure to depress; Vehicle takes longer to stop (extended braking distance); Brake assist warning light illuminated; Service brake assist message on dashboard; Vibrating brake pedal; Ticking noise from engine during brake malfunction

Codes mentioned: N182202780 (Brake Assist Decreased Due to Vacuum Loss), 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control)

Repairs/costs cited: Vacuum pump replacement; one owner's dealer did not repair the vehicle despite diagnosis

Recalls/TSBs owners mention: GM issued Special Coverage Adjustment N182202780 for brake assist decrease due to vacuum loss; however, many complainants report their VINs are not covered by available recalls despite having identical symptoms. NHTSA Campaign 19V761000 mentioned but some VINs excluded.

Brake skipping and loss of braking effectiveness

During braking or reversing, brakes skip or fail to operate properly. Both service brake assist and brake assist warning lights illuminate. One owner reported complete brake failure during highway driving, requiring emergency brake deployment.

When: 84,000 miles in one case; otherwise unspecified

Symptoms owners cite: Brakes skip during stopping or reversing; Brakes fail to operate as needed; Service brake assist warning light illuminated; Brake assist warning light illuminated; Complete brake failure (in one severe case); Inability to stop vehicle with normal brake application

Codes mentioned: 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control)

Repairs/costs cited: No repairs reported for skipping brake complaints

Recalls/TSBs owners mention: Campaign 19V761000 referenced but VINs not consistently included in recall coverage

Unintended brake pulling to left or right with trailer brake system message

Brakes apply unevenly, pulling the vehicle hard to the left or right during braking. A 'trailer brake system failure' message displays on the dash despite the vehicle never having towed anything. Battery drain occurs simultaneously with the message.

When: Unspecified

Symptoms owners cite: Brake pedal pulls hard to left or right; Trailer brake system failure message on dashboard; Battery drains during brake system malfunction; Electrical system cycling off during driving

Codes mentioned: N192261050 (GM service bulletin related to similar issue)

Repairs/costs cited: No repair details provided by complainant

Recalls/TSBs owners mention: GM service bulletin N192261050 exists for this issue; no warranty repair or recall information provided

Vacuum leak causing hard brake pedal after overnight sitting

Vacuum pressure bleeds out of the brake system during overnight vehicle inactivity, causing the brake pedal to feel very hard and require excessive force the following morning. A vacuum leak exists in the system but owners report no recall coverage for their vehicles.

When: Manifests after 6+ months of ownership; occurs after overnight parking

Symptoms owners cite: Brake pedal extremely hard to push after overnight sitting; Vacuum pressure loss over time; Normal brake feel returns after vehicle runs and rebuilds vacuum

Repairs/costs cited: No repairs completed; owner reports dealer and GM deny recall coverage

Recalls/TSBs owners mention: GM and dealer state this model and year not covered under current recall
