    On the 2013-2022 Buick Encore 1.4L Turbo LUJ/LUV, the 1.4L Turbo LUJ (2011-2015) and LUV (2016+) in Encore — and shared Chevy Cruze/Sonic/Trax — develops timing chain stretch typically between 80,000-130,000 miles. Cold-start rattle, then misfire codes, then risk of chain skip. Same engine family used in Opel Astra J (Astra Adam Mokka — see prior Opel issues).

    This issue also affects: Buick LeSabre, Buick Park Avenue, Buick Cascada

    Common Symptoms

    • cold start rattle
    • misfire
    • check engine light
    • limp mode

    How to Fix

    Full chain kit including chain, tensioner, guides, sprockets ($1,200-$2,000). Use dexos1 full-synthetic 5W-30 and stick to 5,000-mile intervals — extended OLM intervals are the dominant cause. Catastrophic chain skip means head rebuild ($3,500+).

    Typical repair cost:$1,200 - $4,000

    On the 2013-2018 Buick Encore, the 1.4L turbo Encore is known for turbocharger failures, often tied to the turbo oil feed/supply line, that cause a sudden loss of power while driving and a persistent check engine light. NHTSA complaints document dangerous highway events where the vehicle abruptly lost acceleration. GM later issued a field action/warranty extension covering 2017-2018 Encore turbochargers for 10 years / 120,000 miles, with the repair replacing the turbo assembly and associated oil-feed seals and gaskets.

    This issue also affects: Buick Cascada, Buick Encore GX, Cadillac CT6

    Common Symptoms

    • Sudden loss of power on the highway
    • Reduced engine power warning
    • Check engine light
    • Turbo underboost
    • Loss of acceleration

    How to Fix

    Replace the turbocharger assembly along with the turbo oil feed pipe seals, oil return pipe gaskets, exhaust/coolant seals, and related hardware per GM's procedure. For 2017-2018 models, check eligibility for the GM turbocharger warranty extension (10 yr / 120,000 mi). Maintain strict oil change intervals to avoid oil-feed line coking that accelerates turbo failure.

    Typical repair cost:$1,200 - $3,000

    On the 2013-2022 Buick Encore, this is the upstream half of the 1.4L PCV story and is often missed. The intake manifold on the LUV/LUJ 1.4T contains a small, non-serviceable orange one-way check valve in the PCV port. Under boost that valve is meant to block pressure from reaching the crankcase; when it fails and is ingested by the engine, boost pressure enters the crankcase, the camshaft-cover diaphragm tears, and the engine develops a large vacuum leak. The result is P1101 (intake airflow system performance) with P0171 (system too lean), rough idle, high idle, stalling and long-term fuel trims in the +25% to +70% range. Owners who replace only the valve cover watch the new one fail within months because the missing manifold check valve was never addressed. A ScannerDanner forum diagnosis of a 2019 Encore documents exactly this: check valve gone from the manifold, 70% fuel trim, fixed by an external PCV kit.

    This issue also affects: Buick LeSabre, Buick Park Avenue, Cadillac Allante

    Common Symptoms

    • Check engine light with P1101 and/or P0171
    • Rough or surging idle
    • High long-term fuel trims (+25% or more)
    • Stalling at idle
    • Whistle at the valve cover after diaphragm tears
    • Repeat valve-cover failure after replacement

    How to Fix

    Pull the PCV hose at the intake manifold and look into the port: if the orange check valve is missing, the manifold is the root cause. Official repair is a new intake manifold (roughly $400-$700 installed) plus a new camshaft cover if the diaphragm has torn ($200-$350). Many owners instead install an external PCV fix kit (CruzeKits or equivalent) that relocates the check valve into a serviceable inline fitting, which is cheaper and prevents the repeat failure. Clear codes and confirm fuel trims return to single digits.

    Typical repair cost:$150 - $900

    On the 2013-2021 Buick Encore, many owners of the 1.4L turbo Encore report the engine consuming oil at an elevated rate between changes, often without an obvious external leak. Low oil levels left unchecked can starve the turbocharger and accelerate engine wear. Consumption is frequently linked to PCV system failure forcing oil through the intake, and to general wear in the LUV/LUJ engine family.

    Common Symptoms

    • Low oil between changes
    • Oil light or low oil warning
    • Burning oil smell
    • Blue exhaust smoke
    • Frequent need to add oil

    How to Fix

    Check oil level frequently between changes and top off as needed. Diagnose and repair the PCV/camshaft cover system, which is a common contributor. Perform a documented oil-consumption test at a dealer; persistent high consumption may require valve cover, PCV, or piston ring/seal service.

    On the 2013-2021 Buick Encore, the 1.4L turbocharged engine (LUV/LUJ family) used in the first-generation Encore is prone to a ruptured PCV pressure-regulator diaphragm built into the plastic camshaft (valve) cover. When the diaphragm cracks, unmetered air enters the intake, producing a loud high-pitched whistle or squeal that owners describe as a boiling tea kettle under the hood, along with rough idle and stalling at stops. GM acknowledged the defect with Special Coverage N202299080, extending warranty on the PCV/camshaft cover to 10 years / 120,000 miles for certain 2014 Encore (and related Cruze/Sonic/Trax) vehicles.

    This issue also affects: Buick LeSabre, Buick Park Avenue, Cadillac Allante

    Common Symptoms

    • Loud tea-kettle / boiling whistle under hood
    • Check engine light
    • Rough idle
    • Stalling at idle or stoplights
    • Vacuum leak

    How to Fix

    Replace the camshaft (valve) cover, which contains the integrated PCV diaphragm; many owners upgrade to a revised cover. The root-cause check valve in the intake manifold should also be addressed (replace manifold or install an external check-valve/PCV bypass kit) to prevent turbo boost from over-pressurizing the crankcase. Check eligibility under GM Special Coverage N202299080.

    On the 2013-2022 Buick Encore, the 1.4L LUV turbo uses a single four-tower ignition coil cassette that sits on the valve cover and fires all four cylinders. Heat cycling cracks the coil body or its boots, and the cassette can lose spark on one or more cylinders at once - a Bob Is The Oil Guy thread on an Encore 1.4T misfire and multiple BuickForums P0300 threads trace the misfire to the coil pack (often with worn plugs) after the PCV vacuum-leak possibility is ruled out. Cylinder 3 is the most frequently flagged (P0303). Because the cassette is one part, a failing coil can present as a random multi-cylinder misfire rather than a single dead cylinder.

    This issue also affects: Buick LeSabre, Buick Park Avenue, Buick Cascada

    Common Symptoms

    • Flashing or steady check engine light with P0300/P0301-P0304
    • Rough idle and shaking
    • Hesitation and loss of power under boost
    • Misfire worse when engine is hot

    How to Fix

    Rule out the PCV/intake-manifold vacuum leak first (fuel trims), then check plug gap and coil resistance. The fix is a new coil cassette (roughly $120-$250 for the part, about an hour of labor) and a fresh set of the correct iridium plugs. Dealer repair is typically $300-$500. Avoid bargain coil packs - repeat failures are common.

    On the 2013-2017 Buick Encore, the Encore uses a column-mounted electric power-steering unit. On 2,295 model-year 2015 Encores built 27 Nov 2014 to 24 Feb 2015, the steering column housing could contact and wear the power-steering printed circuit board, eventually causing a sudden loss of electric assist while driving. GM recalled these under NHTSA 15V146 (GM #15168) and replaced the steering column assembly. Beyond the recall population, BuickForums owners of 2013-2017 Encores report a 'Service Power Steering' warning with heavy steering on cold mornings that clears after a restart; in many of those cases the root cause was a weak battery or poor battery ground starving the EPS module of voltage, and in others the column EPS unit itself needed replacement.

    Common Symptoms

    • Sudden heavy steering while driving
    • Service Power Steering message on the driver information center
    • Steering assist lost on cold starts, returns after restart
    • Power steering warning lamp illuminated

    How to Fix

    For 2015 vehicles in the build window, confirm recall 15V146 was completed - the column assembly is replaced free of charge. For non-recall vehicles showing 'Service Power Steering', have the battery load-tested and the negative battery cable/ground checked first (cheap and frequently the cause). If the EPS module logs internal faults with a healthy battery, the steering column/EPS assembly is replaced, typically $900-$1,600 at a dealer.

    On the 2014-2017 Buick Encore, distinct from the 2019 'manufacturing mode' SDM recall, 2014-2017 Encores (built 9 Jul 2013 to 26 Aug 2016) were part of GM's 3.6-million-vehicle recall 16V651 (GM #16007). Under certain driving conditions the airbag sensing and diagnostic module (SDM) software could enter a diagnostic test routine; while in that test, the frontal airbags and seat-belt pretensioners would not deploy in a crash. Some vehicles that were 'fixed' did not receive the complete software update, so GM issued a follow-up recall 17V437 (GM #17287, 40,683 vehicles across GM brands) in July 2017 to reflash them again. The condition gives no warning to the driver.

    Common Symptoms

    • No warning - airbags and pretensioners silently unavailable during SDM diagnostic test
    • Frontal airbags did not deploy in a frontal crash
    • Possible airbag readiness light in some cases

    How to Fix

    Check the VIN against both 16V651 and 17V437. The remedy is a free dealer reflash of the SDM software; if the airbags had previously deployed the SDM is replaced. A vehicle that only received the 16V651 reflash may still need the 17V437 reflash - dealers can confirm the software level.

    On the 2013-2018 Buick Encore 1.4L LUV turbo (AWD), on 2013-2018 Encore AWD models the rear differential clutch control module (RDCM) sits low at the rear axle where road splash reaches it over time. Water enters the module and corrodes its circuit board. The most common result is loss of all-wheel-drive engagement with a 'Service AWD' / 'Service StabiliTrak' style message and codes C0800 and/or U0136; in rarer cases the corroded module back-feeds the network and causes a dead battery or loss of electric power-steering assist. Owners on BuickForums also describe the rear clutch randomly engaging with a pop or bang and binding in tight turns before the module fails outright. GM addressed this with Special Coverage bulletin 17436-02 ('Loss of All Wheel Drive Operation Due to Corrosion of Rear Differential Control Module'), which extends coverage on the RDCM and its harness for 2013-2018 AWD Encores.

    Common Symptoms

    • Service AWD message
    • Loss of all-wheel-drive function / front-wheel spin only
    • Rear differential randomly engaging with a pop or clunk
    • Binding in tight low-speed turns
    • Dead battery overnight
    • Service Power Steering message or loss of assist
    • DTC C0800 and/or U0136 stored

    How to Fix

    Dealer replaces the corroded RDCM harness and installs an updated RDCM (GM P/N 42463357, tagged with a green dot) and re-secures the harness to its original routing. Check with a dealer for Special Coverage 17436-02 eligibility by VIN before paying - the module and harness were covered well beyond the base warranty under that program. Out of coverage, expect roughly $500-$1,100 for module, harness and labor.

    Typical repair cost:$500 - $1,100

    On the 2013-2019 Buick Encore 1.4L LUV turbo (AWD), separate from the electronic module problem, the rear differential/clutch-coupling assembly on 2013-2019 Encore AWD models (shared with the Chevrolet Trax and Opel Mokka) suffers severe exterior corrosion of its aluminum housing in salt-belt states. The corrosion eats through the case, gear oil weeps out, and the ring-and-pinion and bearings run dry, producing a growl or grind that rises with road speed, clunks on throttle tip-in and binding on turns. An owner on Bob Is The Oil Guy documented a badly rotted differential housing on a 2018 GM vehicle of this family at modest mileage, and BuickForums carries rear-end noise threads on Encores of several years. Because the unit is a sealed assembly, the usual dealer repair is a complete replacement differential carrier, which is expensive on a vehicle of this class.

    Common Symptoms

    • Growling or grinding from the rear that rises with road speed
    • Gear-oil stain or wet corrosion on the rear differential housing
    • Clunk on acceleration or deceleration
    • Binding or hopping in tight turns
    • Low or empty differential fluid on inspection

    How to Fix

    Inspect the rear differential housing for white corrosion, weeping seams and a low fluid level at every oil change once the vehicle is 4-5 years old in a salt state. A housing that is only weeping can sometimes be saved by resealing and refilling; a cracked case or a differential that already growls needs a complete carrier assembly (used units are common because the unit rarely fails internally in dry climates). Dealer replacement runs roughly $1,800-$3,000; a used carrier installed independently is typically $800-$1,500. Under-coating the housing when new slows the corrosion considerably.

    Typical repair cost:$800 - $3,000

    On the 2013-2018 Buick Encore, first-generation Encores with the 6T40/6T45 6-speed automatic are reported to develop harsh or delayed shifts, slipping, and a shudder or surge particularly around the 2nd/6th gear range. A common cause is debris blocking the oil passage that feeds the 2-6 clutch regulator valve, along with worn fluid, failing shift solenoids, and torque-converter lockup shudder. NHTSA powertrain complaints span the early-to-mid model years.

    Common Symptoms

    • Harsh or delayed shifts
    • Slipping between gears
    • Shudder or surge on acceleration
    • Flare into 2nd/6th gear
    • Jerking / lurching

    How to Fix

    Service the transmission with the correct fluid; for shudder, a torque-converter clutch fluid/flush or solenoid replacement may help. Persistent 2-6 slip/flare typically requires valve body/channel-plate cleaning or rebuild. Confirm GM software calibration is current, as updated shift logic addressed some complaints.

    On the 2013-2022 Buick Encore, the 1.4L LUV turbo in the 2013-2022 Encore (same family as the Cruze/Sonic/Trax 1.4T) loses coolant from several plastic-and-rubber weak points that fail in sequence as the engine ages. The water pump develops a weep from its seal, the plastic thermostat/water-outlet housing cracks where it bolts to the head, the turbo coolant feed/return lines and their O-rings seep, and the molded outlet hoses go brittle. Owners on BuickForums describe topping up a quarter cup a week, sweet smells, low-coolant warnings and, when ignored, overheating at highway speed (one 2015 overheated at 59k when brittle outlet hoses let go). Dealers frequently replace the water pump under the 5-yr/60k powertrain warranty, but the thermostat housing and hoses are often declared excluded, leaving owners to pay.

    This issue also affects: Buick Encore GX, Cadillac Allante, Cadillac Catera

    Common Symptoms

    • Low coolant warning / reservoir needs frequent topping
    • Sweet coolant smell after driving
    • Pink/orange crust on the water pump or thermostat housing
    • Coolant drips near the turbo
    • Engine overheating at highway speed
    • DTC P0128 (coolant thermostat) on a cracked housing

    How to Fix

    Pressure-test the cooling system to locate the leak rather than just topping up; a UV dye is the fastest way to separate pump weep from housing cracks and turbo-line seepage. Water pump replacement runs roughly $450-$800 (covered under powertrain warranty if in term). Thermostat housing replacement is $250-$500; an aftermarket aluminum housing is a popular permanent fix. Replace brittle outlet hoses and turbo coolant lines at the same time. Never run the engine with the coolant light on - the aluminum head and turbo do not tolerate overheating.

    On the 2013-2016 Buick Encore, first-generation Encores with the 7-inch IntelliLink system have a well-documented display failure: the screen intermittently goes black or reboots itself while driving, sometimes taking the audio, Bluetooth and the backup-camera image with it. BuickForums has a multi-page 'Black IntelliLink screen' thread and separate 2016 reports; a GM Authority owner thread describes a 2014 Encore radio/nav screen going black and rebooting. Early cases were addressed with software updates to the radio and HMI module; persistent cases needed the display or the radio (HMI) module replaced, which is a costly dealer repair once out of the 3-yr/36k bumper-to-bumper warranty. Since the backup camera renders on the same display, a dead screen also removes the camera view.

    Common Symptoms

    • Center display goes black while driving
    • Radio reboots on its own
    • Backup camera image not shown when in Reverse
    • Touchscreen unresponsive or frozen
    • Bluetooth audio drops with the screen

    How to Fix

    Try the soft reset first (hold Home and Fast-Forward/Seek until the unit reboots) and have the dealer check for a radio/HMI software update. If the blackouts continue, the display assembly or HMI module is replaced - roughly $500-$1,200 at a dealer depending on which module fails; remanufactured units through independent radio shops are cheaper. Document intermittent failures on video before the warranty expires so the dealer cannot claim 'no problem found'.
