2012 Chevrolet Equinox — Known Issues & Recalls

Your engine is consuming oil faster than normal, even though you don't see any leaks underneath or inside the vehicle. You need to check and top off the oil almost daily to prevent the engine from running dry and seizing up. The underlying cause of the oil consumption will need to be diagnosed, which may involve checking piston rings, valve seals, or other internal engine components.

Your engine is burning through oil excessively again, even though you had the recall repair done before. Based on your research, it seems the piston rings installed during that repair may not have been the right size to properly seal and prevent oil from escaping through the exhaust. You're wondering if the repair can be covered again under warranty or recall.

After the dealership performed an oxygen sensor recall on your 2012 Chevrolet Equinox, your check engine light began coming on and off intermittently. Multiple scans have confirmed oxygen sensor fault codes (P0138 and P2271), and the problem has affected your vehicle's performance. The dealership has attempted the recall a second time, but the issue persists and they've had difficulty diagnosing it because the check engine light is intermittent. Resolving this will likely require a proper oxygen sensor replacement or electrical diagnosis of the oxygen sensor circuit.

Your check engine light keeps coming back on even after people have reset it multiple times. You're concerned about safety since you don't know what might fail or when, and the light is your only warning something is wrong. A mechanic will need to read the diagnostic trouble code to identify the underlying engine problem.

Your engine is consuming a lot of oil, which you didn't know about when you purchased the car with less than 130,000 miles. You sometimes hear noise coming from the engine. This may require inspection of the engine for internal wear, leaks, or damaged seals that are causing the excessive oil consumption.

Your vehicle was brought in for a recall repair involving the oxygen sensor and tailpipe emissions. During the repair, the dealership discovered that the recalled part had damaged your catalytic converter, which they said would be covered under the recall. The dealership released your vehicle on 2/14/2025 before the repair was fully complete, stating it was drivable and they were only waiting for a harness. When you attempted to start the vehicle the following Monday to return it for the remaining repair, it made unusual noises, shut off, and won't restart. The repair will require diagnosis and completion of the outstanding work, including harness installation and addressing the engine startup issue.

Your car had an open recall for the oxygen sensor after the catalytic converter. When the dealership investigated, they discovered a cracked exhaust manifold that could leak toxic fumes into the cabin of your vehicle. This is a safety concern that requires repair of the cracked manifold and replacement of the faulty oxygen sensor.

Your Equinox is experiencing severe engine problems that cause violent rocking when you slow down, along with check engine and reduced engine power warning lights. Your vehicle's speed is limited to around 23 MPH, making it unsafe to drive. A mechanic diagnosed faulty crankshaft components and worn pistons that require a complete engine replacement.

Your engine is revving abnormally when you start it, and you're hearing a humming sound from underneath the vehicle while driving. Your check engine light is on. A mechanic found that your catalytic converter has failed, your throttle body has failed, and your exhaust manifold is fractured. These issues will need to be repaired to restore normal engine operation and emissions control.

Your ABS and stability control warning light is on and staying on, with a repair estimate of $4,000. Additionally, your engine is burning through oil quickly—your oil gauge may read 70% full while the dipstick shows empty, requiring you to add 2-3 quarts frequently to prevent valve lifter noise from low oil levels. Without the stability control working properly, you could lose traction in snow or rain, and the engine could overheat and shut down during long drives, creating a dangerous situation on the road.

Your rear suspension trailing arm and subframe have rusted through and separated from the frame, causing your rear wheels to shift out of alignment and making your vehicle unstable and unsafe to drive. If this rusted component completely detaches while you're driving, you could lose control of your vehicle and cause a serious accident. An independent mechanic has confirmed the frame is structurally compromised and unsafe without major repair. Fixing this will require replacement of the rusted frame, subframe assembly, and trailing arm components.

Your power tailgate has a dangerous malfunction where it opens fully, then closes partially, then opens and closes again repeatedly when you use the external switch. The tailgate closes with significant force that's difficult or impossible to stop by hand, creating a serious risk of injury if someone gets caught between the tailgate and the vehicle body. The fix will likely involve replacing the tailgate motor assembly or the electronic control module that operates the power tailgate system.

Your ABS and traction control warning lights came on while driving in heavy rain. When you turned a corner at 35 mph, your front end started to slide, and you nearly lost control of the vehicle. At higher speeds, this could have resulted in a serious accident. The issue likely involves your ABS system, traction control, or brake components not working properly in wet conditions.

Your steering wheel has been getting hot in the center, and your airbag warning light recently came on and then turned off. You're concerned that something isn't working properly with the airbag system. A technician will need to diagnose why the airbag sensor is triggering and what's causing the steering wheel heat.

Your ABS (anti-lock brake) warning light is staying on, indicating a system malfunction. A mechanic diagnosed that the entire ABS system needs to be replaced, which is an expensive repair. The repair will involve replacing the ABS module and related components.

Your car is consuming oil much faster than normal—you need to top it off every month even after an oil change. You may experience engine stalling if the oil level gets too low, as happened during driving on a busy road. Multiple owners and even a mechanic have reported the same issue, though the exact cause of where the oil is going isn't clear. The fix will likely involve diagnosing where the oil is leaking or burning, which could require inspection of the engine, gaskets, or internal components.

Your engine is consuming 2 to 3 quarts of oil every 200 miles, which is much faster than normal. This excessive oil loss suggests an internal leak or burning issue in the engine. You should have the engine inspected to find the source of the oil loss and address it promptly.

Your engine suddenly went into limp mode at 76,000 miles, limiting acceleration to 24 mph and causing loud valve rattling. A mechanic found the oil level was completely empty and added 5 quarts to restore normal operation. The owner reports that 2012 Chevrolet Equinoxes are known for excessive oil consumption due to faulty pistons, which wasn't addressed in any recall.

Your engine is leaking oil from the oil pan seal, which your mechanic discovered during an oil change—the engine was running low on oil. The oil pan uses a liquid sealant rather than a traditional gasket and will need to be removed and resealed. Additionally, your suspension is making noise that sounds like worn bushings, but there's no lubrication point available. Without proper oil levels, your engine could seize while driving and create a safety hazard.

Your driver's side wiper blade has stopped working while the passenger side still functions normally. You've also noticed your engine is consuming oil too quickly—the oil level drops significantly between regular oil changes—and your catalytic converter has been damaged as a result. While recalls exist for both issues for your vehicle's make, model, and year, they don't apply to your specific VIN number. Fixes would likely involve replacing the wiper linkage assembly and addressing the underlying oil consumption problem, which may require engine gasket replacement or valve seal repair.
