Reliability varies across model years of the Chevrolet Equinox. Based on documented issues, problems are most commonly reported in earlier model years. Au7o recommends checking the specific known issues for your target year before purchasing, and having a pre-purchase inspection performed by a qualified mechanic. Our known issues database covers the 2005-2026 Chevrolet Equinox with 58 documented issues documented across 5,570+ owner reports.
The 2.4L Ecotec engine uses low-tension piston rings that fail to maintain proper tension to keep oil in the crankcase. Vehicles consume 1 quart of oil per 800-1,000 miles. This defect can cause premature engine wear, engine failure, and potential fire risk if oil levels drop cri… Repairs typically run $2,000-$7,000. Severity: high.
The 2.4L Ecotec engine is prone to premature timing chain failure due to improperly hardened chains and faulty tensioners. A defective batch of timing chains that were not hardened properly causes the chains to stretch prematurely. When the timing chain fails or jumps teeth on th… Repairs typically run $1,500-$4,000. Severity: high.
A defective oil filter adapter can cause engine oil leaks that may contact hot exhaust components, creating a fire risk. Combined with the excessive oil consumption issue, low oil conditions can exacerbate the problem. Repairs typically run $0-$500. Severity: high.
The electronic power steering (EPS) system can fail intermittently or completely, resulting in sudden loss of power steering assist. This creates a dangerous driving condition requiring significant physical effort to steer. Repairs typically run $100-$1,500. Severity: high.
The fuel pump module fails to consistently provide adequate fuel flow to the engine, causing potential stalling while driving. This creates a significant safety hazard as the engine can stall unexpectedly in traffic. GM issued recall N222372310 affecting 23,164 vehicles. Repairs typically run $0-$0. Severity: high.
The first-generation Equinox commonly uses the GM 3.4L LA1 V6, and owners have repeatedly reported coolant loss, overheating, and eventual head gasket failure. In many cases the problem starts as an external or internal coolant leak, then progresses to overheating, rough running,… Repairs typically run $1,500-$3,200. Severity: high.
The 1.5L turbo (LYX) in 2018+ Equinox is reported to lose coolant with no obvious external leak, leading to overheating and, in some cases, head-gasket failure (coolant entering the combustion chamber). Owners describe the coolant level dropping over time with overheating events. Repairs typically run $1,000-$2,500. Severity: high.
A recurring safety complaint on this generation is failure of the passenger presence/occupant classification system in the front passenger seat. Owners report the air bag warning lamp, 'Passenger Air Bag Off' message when an adult is seated, or intermittent operation depending on… Repairs typically run $400-$1,800. Severity: high.
A well-documented and expensive failure mode: the A/C compressor on the 2010-2017 Equinox platform fails internally and grenades, shedding fine aluminum/metal particles ("black death") that circulate through the entire refrigerant system. Owners notice the A/C suddenly stops blow… Repairs typically run $1,000-$2,200. Severity: high.
Owners of 2023-2024 Equinox models with the 1.5L turbo (LYX) report the engine-mounted high-pressure direct-injection fuel pump failing, often well under 60,000 miles (some as early as 28,000 miles). The pump can no longer maintain rail pressure, so the engine suddenly loses powe… Repairs typically run $1,000-$1,200. Severity: high.
P0700 is not a standalone defect — it is the transmission control module's way of telling the engine computer to turn on the check-engine light because a more specific transmission code is stored. On the second-generation Equinox, which uses GM's 6T40/6T45 six-speed automatic beh… Repairs typically run $300-$900. Severity: high.
The diesel Equinox (1.6L LH7) is prone to NOx-sensor and diesel-exhaust-fluid (DEF/SCR) emissions faults. Failing or out-of-calibration NOx sensors and reductant-injection problems set codes such as P11DB (NOx sensor 1 performance) and P249D (closed-loop reductant control at limi… Repairs typically run $350-$1,500. Severity: high.
GM recalled certain 2024 Chevrolet Equinox (gas) vehicles — along with the Blazer, Blazer EV and GMC Terrain — because door strikers supplied by Brano Group A.S. may not have been heat-treated to GM hardness specifications and can fracture. A broken striker can allow a door to op… Repairs typically run $0-$0. Severity: high.
GM recalled certain 2025-2026 Chevrolet Equinox EV models (and Cadillac Optiq) equipped with optional 21-inch Continental CrossContact RX 275/40R21 all-season tires (RPO QLT). Continental found that tires built during DOT week 4024 (week of October 6, 2024) had inadequate sulfur… Repairs typically run $0-$0. Severity: high.
Third-generation Equinox (2018-2022) uses a camshaft-driven mechanical vacuum pump mounted at the rear of the cylinder head to supply the brake booster (the turbo intake is pressurized, so there is no manifold vacuum). This pump can seize and its drive gear break, suddenly elimin… Repairs typically run $400-$1,200. Severity: high.
GM recalled approximately 2,890 model year 2025 Chevrolet Equinox EV all-wheel-drive vehicles (those NOT equipped with Super Cruise) because incorrect brake system control module software can cause the adaptive cruise control system to fail to engage the friction brakes as expect… Repairs typically run $0-$0. Severity: high.
In early 2026 GM launched a broad recall covering roughly 102,000 Chevrolet Equinox EVs (primarily 2024-2026 model years) over a vehicle-control / propulsion software defect that can cause an unexpected loss of power or loss of propulsion while driving. Related field reports desc… Repairs typically run $0-$0. Severity: high.
AWD Equinox models have a documented pattern of rear drive module and differential-related noise, vibration, and eventual failure. Owners describe whining, grinding, or binding from the rear of the vehicle, especially during turns or at highway speed, and some report loss of AWD… Repairs typically run $250-$2,800. Severity: high.
Water and road debris intrude into the windshield wiper module/transmission ball joints, causing corrosion and excessive wear that detaches the linkage and leaves one or both wipers inoperative — a serious safety issue in rain/snow. GM recalled ~367,800 model-year 2013 Equinox/Te… Repairs typically run $250-$600. Severity: high.
GM's high-feature V6 in the Equinox suffers premature timing-chain stretch, distinct from the covered 2.4L chain issue. Worn chains/guides/tensioners throw off cam-to-crank timing, setting P0008/P0009 (engine position performance) and P0016-P0019 (crank/cam correlation). The clas… Repairs typically run $2,000-$3,500. Severity: high.
