As GM Authority has reported before, the Chevy Equinox crossover has a history of engine power problems stretching back to the 2018 through 2022 model years. If your 2023 through 2025 Chevy Equinox has reduced engine power, a new official bulletin from GM describes the issue and what the dealer can do to fix it.
According to GM bulletin number PIP5927B loss of engine power is only one symptom of this problem. Affected units of the 2023, 2024 and 2025 Chevy Equinox are likely to generate one of several Diagnostic Trouble Codes (DTCs) in addition to this symptom, which include the following:
- P0237 (Manifold Absolute Pressure (MAP) sensor A, turbocharger (TC) circuit low input)
- P0101 (Mass Air Flow (MAF) Sensor Performance)
- P1101 (Intake Air Flow System Performance)
- P0299 (Engine Underboost)
This issue affects the only engine offered for the 2023 through 2025 Chevy Equinox,  the turbocharged 1.5L I4 LSD gasoline engine developing 175 horsepower. The dealer service personnel should check the Charge Air Inlet Pipe if low engine power and one or more of the above DTCs is present.
The low engine power and DTC problem may be caused by splits or shredding of the anti-abrasion sleeve over the Charge Air hose. The hose itself should then be inspected to see if it is split. Such a split could cause hose swelling and low engine power, either directly through an air leak or by creating improper readings in the boost control system.
If the inner hose and/or the abrasion sleeve are found to be damaged at the same time as the above conditions are present, dealer service personnel should carry out replacement of the Charge Air Inlet Pipe assembly. This will remedy the low engine power issue if hose damage is the root cause.
A similar problem can also affect the 2023 through 2025 GMC Terrain. As a reminder, the 2025 Chevy Equinox launches a new generation of the crossover, with structure provided by an updated variant of the GM D2 platform. The vehicle has been in production since May 2024 at the GM San Luis Potosà plant located in Mexico.

’25s already involved. Just fantastic. Spend a lot more and get the same issues.
Could have kept the Opel diesel in there to help with reliability.
Let’s face it! The crop of car designers and engineers are below average compared to a few years back. When buying a new vehicle, recalls are now part of the game. We are hiring people who are just not qualified. The rest are too busy playing with their cell phones and FACEBOOK or TIC TOK!
Out-sourcing … what could possibly go wrong?
There you go! Another problem related to turbo- and super-charging!
There hasn’t been a decent Equinox since the naturally-aspirated V6 was dropped from the option sheet.
Are politics determining what most people would think and/or think or do? Been a gm customer and for a while even sold many chevy/gmc is beyond me why ‘Mary ‘ or whoever makes decisions at gm has not consider/develop a decent hybrid program. Ev’s are not for everyone and already have platforms that can be suited for such a concept proven by other manufacturers. Seems like with the exception of the Corvette program gm is always behind, purposely or dei? Get with the times or face the inevitable…
Gto guy I have to say I love my 2.0 L. Great gas mileage and this engine makes this vehicle fly, very responsive. Only downside I use mid grade gas, 89 octane . No reason to use the premium grade that is suggested. And it can tow 3,500 lbs. Now if only gm would give us choices
