Chevrolet Equinox Engine problems by year

still would not start and the wheels remained locked. The dealership then replaced the brake control module per TAC guidance. The dealership told me the vehicle started after the module was replaced and the locked wheel issue was resolved. The vehicle was at the dealership for more than 30 days. In a separate earlier incident, while I was driving on the freeway at approximately 75mph with my young child in the vehicle, the Equinox downshifted extremely hard and lost all electronic functions. This incident happened twice in one trip. I am including this incident as a prior safety history. I am asking NHTSA to review the no-start and locked wheel incident and the dealership's repair findings for a possible safety defect.

completely surprised to find out this huge safety issue. Look how dangerous this would have been if I was on the interstate in [[redacted]] or some other really big city, and yet unable to move my car out of the line of traffic. As I had the car for only a week, I was shocked when this happened and knowing this will happen not just you run out of gas, but also when the engine shuts off and won't restart. This needs addressed! Thank you INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Less than a week after they replaced the sensor, the check engine light came back on. I re-ran my OBD scanner, and it showed the same exact error code as before. Basically, the sensor was replaced, but the issue has not been resolved. I've been keeping tabs on GM's bulletin regarding this issue (which is apparently a known issue), and I'm concerned about the fact that there haven't been any recent updates regarding a fix. GM's own recommendation to dealerships is to simply clear the error code and return the vehicle to the customer... I can clear the code myself, but that certainly does not prevent it from coming back. At this point, the error code has been cleared at least 10 times, and it always comes back within a few days of clearing. This becomes a safety issue because we are quickly approaching the Winter months again, and the temperatures get very cold where I live. When the check engine light is on, my car fully prevents me from using the remote-start feature. I'm unable to remotely start the car from both my key FOB, and from the MyChevrolet app. Thank you for your attention to this matter. My hope is that GM's engineers find a real solution to this problem, and quickly! Because, as I said before, this has been an ongoing issue for many months, and I've yet to see any meaningful movement from GM on this issue.

than these being isolated gasket or seal failures. Excessive crankcase pressure can force engine oil past seals and gaskets, resulting in significant oil loss. This creates a safety concern because an engine oil leak can worsen suddenly and result in substantial loss of engine oil, potentially causing engine damage or engine failure while the vehicle is being driven. Oil contamination of the serpentine belt is also concerning because it can affect the belt's ability to operate properly and may result in belt failure and loss of engine-driven components. I believe the PCV/crankcase ventilation issue should be investigated as a potential underlying defect in the 2016 Chevrolet Equinox. I am requesting that NHTSA investigate whether there is a recurring safety defect involving the PCV system, excessive crankcase pressure, resulting oil-seal/gasket failures, and associated oil contamination in these vehicles. I am also concerned that owners may be required to pay for multiple repairs to correct the consequences of an underlying PCV/crankcase pressure problem. The vehicle is currently in need of repair for the PCV system, excessive crankcase pressure, front main seal, timing cover gasket, and oil-contaminated serpentine belt. The timing chain may also require replacement depending on the inspection and extent of damage. Documents are included.

it happened, someone was pretty close behind me. The car stopped hard, real hard, but let go quickly enough to accelerate before a collision. The second time, there was no one in front or behind us, and we were safe. It hadn't happened in a while, today. We've downloaded 2 or 3 software update, and I was hoping it fixed the issue. It did not. Today the car stumbled and the rpm's jumped. I feel like the car momentarily braked while I was accelerating.

This report could prevent a fatal accident. We have seen multiple of these same vehicles all over places like facebook marketplace and on the side of the road. They are dangerous vehicles and I've heard multiple accounts in which even your dealerships dont know how to fix it. I believe you have a responsibility to consumers to pull these cars from use and make it right to all who have not gotten what they paid you for buying this car from you.

a fixed orifice built into the intake manifold instead of a replaceable PCV valve. In cold weather, moisture and vapor inside the crankcase can freeze or accumulate as sludge within this orifice. When the orifice becomes obstructed, the PCV system can no longer vent crankcase gases properly, causing internal pressure to rise significantly. This condition is most common in sub-freezing temperatures and is documented in multiple GM technical bulletins. When crankcase pressure increases beyond normal operating limits, the pressure seeks the weakest escape point, which is often the rear main seal. As pressure builds, the rear main seal can rupture suddenly, resulting in an immediate and severe oil leak. This failure can occur without warning and may lead to rapid oil loss, environmental contamination, and potential engine damage if the vehicle continues to operate. The defect is inherent to the PCV system design and is not related to owner maintenance practices. General Motors has been aware of PCV system obstruction issues in the 2.4L Ecotec engine since at least 2013, when internal service bulletins first documented rear main seal failures caused by crankcase over-pressurization in cold weather. GM issued additional bulletins in 2014, 2016, and 2019, each reiterating the same failure mechanism. In 2014, GM created Special Coverage Adjustment 14882 but many vehicles equipped with the same engine and PCV design were not added, including mine.

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.

I also noticed many other owners of my vehicle have the same complaint via online forums and even after several replacements from GM the issue persists which is unacceptable. The next issue are the rotors. They most likely are warped as when I step on the brakes the steering wheel vibrates slightly and the car shakes slightly which is not safe. Again, McGuire Chevy in newton dismissed it saying normal. And lastly, the front end of the car shakes when starting vehicle with or without the air conditioner on. It shakes for 10-30 seconds and you can feel it strongly in the brake pedal area as well as rest of the front end of vehicle before going away which seems unsafe, yet the first dealer Mcguire's said it's normal. I am having these issues looked at by a local GMC dealer and hope they rectify the issue or else GM may need to do a buyback if they can't fix the issues and keep saying it's "normal". They opened a case with GM for the shaking so far not the other issues yet so we will see. Honorable mention is the blend door actuator making a noise (another known issue) on this car via online forums making a noise every time you go from hot to cold and vice versa. Mine is affected to just not severely but enough to where it's very irritating and it's had this issue since new and the McGuire dealer said it's normal..... at this point GM needs to issue recalls instead of dismissing customers.
