What stands out
Owners have filed 38 engine complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA engine complaint has been filed on this vehicle in over 14 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This service bulletin advises of a new fuel injection cleaner kit used for decarbonizing the intake valves to correct conditions of rough idle, Crank no start, extended crank or misfire, MIL with DTCs, and explains how Top Tier fuels should be used to reduce carbon build-up.

The failure pattern owners describe
Owners describe widespread engine stalling and power loss with no warning, often at highway speeds and in heavy traffic. The stalling occurs during acceleration, braking, normal driving, or even idling at lights. Some reports include hard starts, rough idle, and loss of power on inclines. The check engine light frequently illuminates, sometimes along with fuel gauge malfunction—reading empty despite a full tank.
Several owners report difficulty restarting after stalling, requiring multiple attempts. One owner experienced a catastrophic engine failure (rod cap separation causing piston failure) at 60,000 miles. Multiple complaints cite the anti-theft system disabling the engine by cutting fuel to injectors; others mention ignition switch failure, timing chain failure, mass airflow sensor defects, and canister vent solenoid issues. Two fires are documented—one with heavy smoke and engine shutdown, another with rapid escalation to explosion. Serpentine belt and hose blowouts appear in separate complaints. One owner reports oil disappearing weekly with no visible leaks.
Repairs are inconsistent: fuel pumps replaced (sometimes twice) without solving the problem; PCM and throttle body replaced; intake sensors, catalytic converters, and battery/starters replaced—often without permanent resolution. Dealers frequently cannot duplicate the failures. One owner spent over $1,400 across four repair attempts without success. Several owners note these failures recur after attempted repairs, some within days or weeks.

Failure modes owners describe
Engine stalling without warning
Complete loss of engine power and motive force during driving at various speeds or while stopped. Loss of steering assist, braking power, and dashboard lights occurs in some instances.
When: Occurs at highway speeds (35–60+ mph), in traffic, on inclines, and at idle. Some instances reported within weeks of repair attempts; failure mileages range from 35,000 to 155,000 miles.
Symptoms owners cite: Engine cuts off without prior warning or hesitation; Vehicle coasts to shoulder or comes to stop in traffic lane; Power steering and power brakes lost when engine dies; Check engine light may or may not illuminate; Difficult or multiple restart attempts required; Recurrence after sitting for period (sometimes 1 hour before restart possible); Hazard lights and some electrical systems continue to operate in some cases
Codes mentioned: Check engine light (code not specified in most narratives), Anti-theft light flashing (narrative #2), Small/large EVAP leak code (narrative #35)
Repairs/costs cited: Multiple repair attempts document the problem but do not resolve it. One owner's fuel pump replaced twice without success. PCM and throttle body replaced in one case, followed by recurrence 30 days later. One dealer was unable to diagnose or duplicate the failure.
Recalls/TSBs owners mention: Ignition switch replacement identified in narrative #3 (out of warranty, $578.38, GM refused refund). One narrative (#1) mentions PCM replacement under factory warranty after initial paid repairs failed. Anti-theft system implicated but no manufacturer fix documented; owner notes lack of recall despite span of over seven years.
Fuel system malfunction (gauge reading/fuel delivery)
Fuel gauge reads empty or fluctuates erratically despite full tank; check engine light illuminates; fuel delivery disrupted causing stalling or inability to start. Anti-theft system blamed in one case for cutting fuel to injectors.
When: Reported at 60,000 miles and up. One instance within 6 months of purchase on pre-owned vehicle. Occurs intermittently.
Symptoms owners cite: Fuel gauge displays empty when tank is full; Fuel gauge fluctuates between empty and full; Engine stalls when fuel gauge shows empty; Check engine light illuminates permanently; Difficulty starting after refueling; Anti-theft light flashing with buzzing alarm in one case; Engine quits during driving, then restarts after delay
Codes mentioned: Code for fuel supply problem to injectors (narrative #2), Check engine light (narratives #8, #9, #13, #31, #32)
Repairs/costs cited: Narrative #2 describes replacement of two fuel pumps (both working properly) without resolving issue; electrical system checked, defective fuse box replaced, bent plug repaired. Narrative #24 reports fuel pump replacement followed by recurrence of failure. Narrative #8 quotes $800 repair cost for fuel gauge/check engine issue. One shop was unable to register failure codes despite problem occurring intermittently and being documented.
Recalls/TSBs owners mention: Narrative #8 owner reports many others have same fuel gauge and air conditioning issues, suggesting GM awareness; no recall mentioned. Narrative #2 notes no bulletins or recalls available; owner alleges Chevy continued manufacturing with known defect for over seven years.
Ignition switch failure
Ignition switch malfunction causes complete engine shutdown without warning. Heavy key chain weight implicated in one case. Failure can occur during driving or when attempting to start vehicle.
When: Narrative #3: 35 mph, shortly after fuel pump repair; narrative #4: on railroad tracks; narratives #3 and #4 mileages unknown or not specified.
Symptoms owners cite: Engine shuts down completely with no prior falter; All automatic systems fail (brakes, steering, dashboard lights); Vehicle cannot be restarted immediately or with difficulty
Repairs/costs cited: Narrative #3: $578.38 out-of-warranty repair at Serra Chevrolet (ignition switch replacement). Narrative #4: ignition switch contact implicated; owner did not receive recall notice from GM prior to accident.
Recalls/TSBs owners mention: Narrative #3: GM refused refund, citing out-of-warranty status; no recall stated to exist at time of complaint. Narrative #4: Vehicle later confirmed to be on GM recall list (owner found out 2.5 years after accident).
Engine mechanical failure (rod cap/piston failure)
Rod cap separated from connecting rod, causing piston to shoot upward and blow hole in engine block. Loud popping sound, heavy smoke, and burning oil reported.
When: 60,000 miles
Symptoms owners cite: Loud popping sound from engine; Heavy smoke rolling from under hood; Burnt rubber smell; All gauges light up on dashboard; Engine dies immediately; Smoke continues until oil burns off; No warning prior to failure
Repairs/costs cited: Diagnosis: rod cap came off while piston in up position; fuel forced piston down, blowing hole in engine side. Engine required replacement. Owner questions what caused cap to come off.
Cruise control malfunction
Cruise control cannot be disengaged; vehicle accelerates uncontrollably to redline RPM. Owner forced to place vehicle in neutral to control speed.
When: Highway, interstate driving
Symptoms owners cite: Cruise control engages and vehicle increases speed and RPMs uncontrollably; Brake application does not disable cruise control; Cruise off button on steering wheel does not work; Engine reevs to redline RPMs when placed in neutral; Engine rerevs to redline immediately upon ignition restart
Engine fire
Two separate fire events reported: one with smoke and shutdown; one with rapid escalation to explosion. Both occurred while vehicle in operation on highway.
When: Narrative #22: while driving on Interstate 80; narrative #33: while driving westbound on Ohio Turnpike
Symptoms owners cite: Thick black smoke from under hood (narrative #22); Smoke from underneath hood (narrative #33); Smoke fills interior of vehicle (narrative #22); Fire intensifies rapidly to explosion, blowing hood and smashing windshield (narrative #22)
Loss of acceleration and deceleration failure
