2019 Chevrolet Blazer
L / 2LT / 3LT / RS / Premier (2nd gen, 2019–2023)
Monitor

The reborn Blazer is a sharp-looking mid-size crossover but first-year quality was inconsistent. For 2019 the choice is the 2.5L four or the 3.6L V6 — the 2.0T that shows up in a lot of Blazer buying guides was not offered until 2020, so ignore 2.0T-specific advice when shopping a 2019. The V6 is the one to have. The main concerns are 9-speed automatic rough shifts, infotainment glitches, and first-year build variance. Prefer 2021+ with the V6 if you can stretch.

Top concern
Engine / Transmission

Powertrain

2.0T oil consumption (LTG engine) — 2020+ cars only

High Risk
The 2.0T LTG engine in the Blazer had documented oil consumption complaints — some owners report 1 qt per 2,000–3,000 miles. GM did not issue a recall.
Check dipstick immediately. Ask owner how often they add oil.
Est. cost: $0–$2,500 Source: NHTSA complaints / GM TSBs

9-speed automatic rough shifts (both engines)

Monitor
The GM 9T65 9-speed automatic is prone to harsh shifts, shuddering, and hunting between gears. Software updates help but don't fully resolve all cases.
Test all city and highway throttle scenarios. Any shudder or harsh kick = request TSB update history.
Est. cost: $0 software update; $3,000+ if transmission hardware needed Source: GM 9-speed pattern

3.6L V6 (LGX) — more reliable choice

Low Risk
The 3.6L LGX V6 in the Premier trim is significantly more reliable than the 2.0T. No widespread failure modes.
Standard oil check and cold-start idle. Smooth delivery expected.
Est. cost: Routine maintenance Source: GM LGX reliability history

Electrical

Infotainment glitches

Monitor
Early Blazers had Chevrolet Infotainment 3 freezing and CarPlay connectivity issues. Software updates resolve most.
Test full CarPlay/Android Auto pairing. Reboot infotainment and verify quick restart.
Est. cost: $0 update Source: GM infotainment TSBs

Recall

Front brake hose recall (select 2019–2020)

High Risk
Some 2019–2020 Blazers were recalled for front brake hoses that could chafe and develop fluid leaks.
Run VIN at nhtsa.gov/recalls.
Est. cost: Free dealer repair Source: NHTSA recall

Documentation

Service records + oil change frequency

Monitor
On the 2.0T engine, oil change frequency is the key predictor of oil consumption severity.
Request all records. 2.0T with no records = risk premium.
Est. cost: n/a Source: AutoVetting editorial

NHTSA Recalls (verify completion via VIN)

Brake hose
Severity: High
Front brake hose chafing — fluid leak risk on select 2019-2020. Remedy: Free dealer brake hose replacement.
