A competent, forgettable mid-size sedan wearing a 1.5L turbo engine with a genuinely scary vacuum pump/timing chain failure mode — buy the 2.0T LT or skip the base engine entirely.

Every documented failure, earliest first

Ordered by the mileage the problem typically appears. VERY HIGH confidence means it's tied to a documented NHTSA recall, and 2 of these are rated Critical.

0k–40k mi● CriticalvariesVERY HIGH
1.5T ECM software bug disabling fuel injectors, causing stalling or no-start (subject of NHTSA recall)
How to catch it: Confirm recall N182347760/software update was completed by VIN lookup on GM's recall site, not just 'closed' on paper.
Source: documented (NHTSA recall)
0k–30k mi● Watch$0–$200MODERATE
'Please Shift to Park' false message preventing shutdown, tied to shift interlock/BCM software
How to catch it: If it happens, cycle through gears slowly and fully seat into park; document occurrences for a warranty software update claim.
Source: multi-source pattern (AI synthesis)
20k–60k mi● Watch$150–$400MODERATE
Backup camera image dropout/freezing (loose harness connector or camera module)
How to catch it: Wiggle-test the camera during a pre-purchase inspection while in reverse; it's usually a connector fix, not a full module.
Source: multi-source pattern (AI synthesis)
30k–70k mi● Plan$300–$900VERY HIGH
Intermittent 'Reduced Engine Power' warning tied to throttle body/electronic throttle control sensor faults
How to catch it: Clean/inspect the throttle body at first sign of the warning; don't ignore it since some owners report brake assist loss during the power-reduction event.
Source: documented (NHTSA recall)
40k–90k mi● Watch$150–$2,000HIGH
9-speed automatic (in 2.0T/some 1.5T) harsh shifting or hesitation from valve body/TCM calibration
How to catch it: Have the TCM software checked/updated at any dealer visit — GM issued multiple calibration updates for shift quality.
Source: owner-reported (31 NHTSA complaints)
55k–90k mi● Critical$4,000–$7,500VERY HIGH
1.5L turbo (LFV) vacuum pump seal failure sending metal debris through the engine, damaging the exhaust camshaft and timing components
How to catch it: Get oil analyzed at every change past 50k and watch for metallic sheen or sudden oil consumption; some owners proactively swap the vacuum pump seal for ~$300-500 before it fails catastrophically.
Source: documented (NHTSA recall)
