Filed Sep 23, 2026 · Electrical · 192,000 miles · NC

Odometer Fraud. The contact purchased a 2014 Chevrolet Equinox. The contact stated that after purchasing the vehicle from an independent dealer, the check engine warning light illuminated. The vehicle was taken back to the dealer several times and the check engine warning light was reset; however, the check engine warning light immediately illuminated while driving the vehicle. The vehicle was then taken to another independent mechanic, and an OBD-II scanner was attached, and it was discovered that there was a mileage discrepancy. At the time of purchase, the mileage was 112,000 and at the time it was discovered that the mileage was 192,000.

Component Failure & Availability: A GM remanufactured 2.4L engine block, installed as a replacement in July 2025, suffered a catastrophic internal failure (blown head gasket) within 11 months of installation. The vehicle and the component are currently in the owner's possession and are available for inspection upon request. Safety Risk: A blown head gasket with an internal coolant leak into Cylinder #3 causes immediate engine overheating, severe engine misfires, and a loss of motive power. If this defect causes the engine to stall while the vehicle is in motion, the driver suddenly loses power steering and acceleration, directly compromising the safe operation of the vehicle in traffic. Confirmation by Service Centers: The catastrophic failure was formally reproduced, pressure-tested, and confirmed by an independent service center. Inspection by Manufacturer/Others: Following the independent confirmation, the vehicle was inspected by an authorized manufacturer dealership. During this inspection, the authorized dealership executed an unauthorized teardown of the engine block and sublet the engine head to a third-party machine shop, physically altering the failed component prior to manufacturer review. Warning Lamps & Symptoms: A check engine light illuminated shortly after the engine's initial installation. The authorized dealership evaluated the vehicle, reset the diagnostic trouble codes (DTCs), and released the vehicle back onto the roadway without properly diagnosing the warranted engine block. This allowed a defective and degrading powertrain component to remain in operation until failure occurred.

Had to get engine replaced 2 months after I bought it in May 2022, warranty covered the replacement. Ongoing issues with catalytic converters, O2 sensors, check engine light coming on due to those reasons for approximately almost 2 years now. Powertrain (Stablitrak, ABS & ECO) stopped working 6 months after purchase - stablitrak warning light came on, took to dealer that I bought it from, quoted almost $900 to fix it, then took it to a private shop then had them fix it due to affordable cost, but somewhat still having some issues. Now Equinox is burning through oil fast. I can bring it in upon request via TEXT ONLY as that I'M DEAF. Those issues have put my children's and my safety at risk because the powertrain caused my Equinox to shut off in the middle of the highway going uphill and other times as I was driving with my kids. All of those need to be fixed by the manufacturer or totaled and I get reimbursed for it. Can provide receipts of repairs & quotes to repair upon request via email.

The most noticeable things wrong are the RPMs and the oil consumption. The RMPs fluctuate at idle, hinting at a misfiring of the pistons, which you can hear when it sits at idle. The second thing is I top off the oil with a quart of oil every gas fill up. The engine light keeps popping on even after engine repairs are done. The exhaust manifold and catalytic converter had to be fixed and that didn't solve the problem. The pistons' psi was tested and one piston had a psi of 70 while the other 3 tested to 125 psi. This is low for all the pistons with a possible broken seal on the one or something else. Chevy recommended 7500 miles between oil changes, but it should be 3000 to 5000. I think in the car's early life, oil changes were not as frequent as they should have been causing damage to the engine that is showing problems now. Having to add a quart of oil at every gas fill up can cause serious damage to the engine and other parts of the car as well, and already has. I will attach a recent repair at Chevy and screenshots of what Google said Chevy recommended for these cars at first. Now realizing that 7500 miles is more than twice as long as it should be for an oil change, Chevy will say 3,000-5,000 for an oil change. But now the range is 3,000 to 7,500. This is not reliable information for these cars. I don't trust my vehicle to go over 3,000 miles due to the oil consumption. The RPMs still fluctuate and the engine light came back on. I suspect something deeper in the engine is wrong, which if it is not fixed, more damage to the engine and car is inevitable.

Safety Complaint: Engine Stall/Loss of Power at Highway Speeds – 2014 Chevy Equinox Incident Details: • The Failure: While driving, the vehicle suddenly stopped responding to the accelerator. I was forced to navigate through highway traffic to the shoulder with no engine power. Once stopped, the vehicle would not restart. • Warning Signs: Leading up to the event, the Check Engine light and Battery light flickered intermittently. • Diagnostic History: Prior to the breakdown, a technician replaced the starter and checked the battery, yet the Check Engine light remained on. The engine exhibited high RPMs (reaching 3,000+) during normal acceleration before the total failure. • Safety Risk: This defect caused a complete loss of propulsion in high-speed traffic, placing myself and my infant in immediate danger of a high-speed rear-end collision.

Service Stabilitrak, Power Steering light, Check Engine light. Door locks lock and unlock continuously. Randomly has No acceleration, causes jolting at a low speed. Available for inspection asap. The code “UO101” comes up in a diagnostic test. Overall, the car basically shuts down while driving at no specific speed. Safety of myself and others is at risk because this can cause an accident resulting in being rear ended/collision with car and other vehicles as it randomly happens when driving. I took my car to the dealership on 3/5/25 and expressed this issue and they could not diagnose it as it was not physically happening after I dropped it off to them. They had the car for 4 days and couldn’t duplicate the issue. They gave back the car and told me there was no issue with the vehicle and it is continuing to happen again. They told me to get proof of the incident on video when it happens again. (I was able to get a video today 4/3/25) There is no warning before this event happens. It will go away and not happen for a few days and then the next day it is not drivable. I am concerned for the safety of myself and others and would like to find the cause of this once and for all. I’d like for the dealership to not send me away without a reason why this is happening or fixing my vehicle.

I got to work and my check engine light came on. As I was parking I received an error message that said decreased engine power. I turned off the car and the car would no turn back on. I had it towed to my mechanic and he told me today that the engine was low on oil. That caused the timing chain tensioner to relax the chain and the timing jumped. When that happens in those engines it damages the cylinder head. The engine will need a new cylinder head and a rebuild of the timing system etc. That would include new pistons as well. That would be about 5500 to do or I’d need to buy a new engine would be about 7k or just over installed. I was well within the oil change guidance on the sticker as well as the oil change guidance in the car menu.

I was driving in busy traffic with no warning signs, no check engine lights when all of a sudden my engine lost power an would not restart. I had to get a tow from Kentucky to Michigan to a near by Mechanic where he ran a boroscope. The timing chain failed which then valves hit the pistons. I know this has been a big problem for this year equinox.

high oil consumption, plugged/damaged PCV valve. This is a known problem with 2010-2014 chevy equinox and a special coverage was issued in 2015, but not all affected vehicles were included in this special coverage, but my vehicle was not included even though the model, year, mileage, and specific issue are all the same as other equinox's that do fall under this special coverage. The special coverage needs to be extended to additional vehicles and Chevy will not address this complaint from me directly. The safety issue is that this problem was going on for months, but the check engine light did not go off to alert me of an issue. I noticed a sound when the vehicle was idling and when my car was suddenly not making it to the next scheduled oil change without being extremely low on oil. Had I not noticed the sound or checked my oil level on the spot (which the average consumer may not due) my engine would have seized up on the highway because it was down 3 quarts even though I had a recent oil change. The car does not make it between standard oil change time frames of 3,000-4,000 miles due to the heavy oil consumption from the defective pcv valve.

“Check engine” light came on recently (September 30th) accompanied by a rattling noise and smell of something burning inside the vehicle. Stopped at O’Reilly’s Auto Parts to have them pull the code before heading to auto shop. Code pulled was P0014 stating issue with exhaust camshaft. Took vehicle to Techway Automotive shop for diagnostic and let them know the code that was pulled at O’Reilly’s. Mechanic completed diagnostic and stated vehicle is consuming oil rapidly causing the engine pistons to “come apart”, specifically the piston rings and seals due to the high oil consumption and that the engine will give out sooner or later, worse case scenario the engine will blow or will cause a fire. Mechanic stated this is a common issue with these vehicles and it cannot be repaired, only complete engine replacement will “fix” the issue but would still require frequent oil level checks every 1000 miles or less. Burning smell and loss of power is very concerning to myself and passengers safety. I have found multiple accounts from others with the same year, make, model and engine type dealing with the same issues or worse. Several have already experienced the worst of it which is their engine catching fire. I was unaware of this being an ongoing issue until it happened to me and I started finding all of these other accounts of the same issues but no sign of recall for this vehicle even though there appear to have been recalls and class action suits filed for older and newer vehicles of the same make and model with similar issues. This needs to be addressed and repaired or fully compensated by the manufacturer since they have been aware of this problem since their 2010 models.
