A Chevy Cruze reduced engine power message tells you the engine has entered a limited-power state. GM bulletins link that state to several different faults, so the model year and engine on your car decide which bulletin applies.
The documented Chevy Cruze reduced engine power cases differ. Some show no stored codes, one 2012 to 2013 case follows running out of fuel, and later bulletins point to a brake pedal sensor or a wiring connector.
GM bulletins are written for trained technicians, so this page summarizes them and does not diagnose your car. Reduced power can make merging or passing unsafe.
What a Chevy Cruze Reduced Engine Power Message Means
A Chevy Cruze reduced engine power message means the car has entered a limited-power state, and a January 2015 GM bulletin says it can appear with little or no noticeable loss of power.
The January 2015 bulletin, GM bulletin PIP5262, describes a message on the Driver Information Center with no diagnostic trouble codes (DTCs) set. A driver may see the message and feel no change in speed or acceleration, so the dashboard message alone does not prove that engine output has dropped.
The same bulletin says the Chevy Cruze reduced engine power message can also appear when the vehicle runs out of fuel. Checking the fuel level is therefore a sensible first step, before any scan tool work or parts purchase.
Owners should not assume every chevy cruze reduced engine power case is the same. The sections below separate the cases GM documents, so you can match your symptoms to one of them.
Which Cruze Years and Engines Each GM Bulletin Covers
The four GM bulletins checked for this Chevy Cruze reduced engine power page cover Cruze models from 2011 to 2019, and only the 2014 and 2015 bulletins name the 1.4L turbo engine.
| Bulletin | Date | Cruze models | Engine | What it covers |
|---|---|---|---|---|
| PIE0289A | June 2014 | 2011 to 2014 | 1.4L turbo (RPO LUJ or LUV) | Intermittent reduced power with no DTCs |
| PIP5262 | January 2015 | 2012 to 2013 | 1.4L turbo (RPO LUJ or LUV) | Driver Information Center message with no DTCs; possible out-of-fuel cause |
| TSB 07-06-04-019F | November 2017 | 2018 and prior GM cars and light trucks | Not engine-specific | Malfunction indicator lamp with reduced power and DTC P2138; harness connector water-intrusion repair |
| PIT5994 | March 2023 | 2012 to 2019, automatic transmission | Not engine-specific | Reduced or low power under acceleration with no DIC message; brake pedal position sensor |
The table covers only the bulletins this page could verify for the Chevy Cruze reduced engine power issue. None of these bulletins is written for a Cruze newer than the 2019 model year, so a newer car needs a VIN check with a dealer.
A 2016 Cruze bulletin, 18NA171 from July 2020, is a different case. It describes a rough running engine with the malfunction indicator lamp on, and it calls for a throttle body repair and reprogramming. It does not mention reduced power, so it should not be read as a cure for a Chevy Cruze reduced engine power message.
Intermittent Reduced Power With No Trouble Codes
GM’s June 2014 engineering information for 1.4L turbo Cruze models says the chevy cruze reduced engine power condition is intermittent and sets no DTCs, so the data must be recorded before anything is cleared. The bulletin, PIE0289A on NHTSA, applies only after a customer has complained about the concern and the case appears in GM’s warranty history. It also states that it is not a recall.
Technicians follow these steps in order:
- Ask the customer about the weather, how long the drive lasted, whether it was city or highway driving, the fuel level, and whether the message appeared on the dashboard.
- Before clearing codes or running a drive cycle, record the GDS2 Reduced Engine Power History parameter in TAC Data.
- If that history reads anything other than NONE, call GM Technical Assistance and take no further action.
- If the history reads NONE and the concern is not current, check all modules for DTCs.
- If no DTCs appear and the concern cannot be repeated, disconnect the 12-volt battery for five minutes, reconnect it, and confirm the message is cleared.
Step 2 matters most. The bulletin warns that a code clear or a road test can erase the evidence, so an owner who clears codes before a shop reads them may lose the record a technician needs.
The February 2014 version of this bulletin, PIE0289, handled that step differently. It told technicians to install the latest calibrations or replace and reprogram the engine control module (ECM) when the history was NONE. The June 2014 revision changed step 2 and says to discard the earlier version.
When Running Out of Fuel Triggers the Message
GM’s January 2015 bulletin says that running a 2012 to 2013 Cruze out of fuel can display the Chevy Cruze reduced engine power message, and the message stays on until the battery has been disconnected for five minutes.
To confirm this cause, the bulletin has the technician read the Reduced Engine Power History under TAC Data. A readout of “Engine Powered Hybrid/EV Battery Charging Unavailable” likely means the car ran out of fuel. The fix described is short:
- Disconnect the battery for five minutes, then reconnect it.
- Reset the history to none with the GDS2 clear codes function.
- Test drive the car and confirm the message does not return.
This bulletin describes one case, so it does not cover every chevy cruze reduced engine power warning. If the message returns after the test drive, the cause is outside this bulletin, and the steps in the earlier section, which begin with recording the history, apply.
The Connector Repair Tied to Code P2138
GM bulletin 07-06-04-019F, revised in November 2017 for 2018 and prior GM passenger cars and light-duty trucks, covers an intermittent malfunction indicator lamp with Reduced Engine Power and DTC P2138, an accelerator pedal position sensor 1-2 correlation code. It blames water intrusion into the instrument panel to body harness connector, which carries the pedal sensor signals to the engine computer. The repair is to find and fix any water leak, then inspect and repair that connector.
The bulletin also warns that aftermarket equipment can set P2138, so a shop checks for it first. The full steps are written for technicians. The bulletin is not specific to the Cruze, so a Chevy Cruze reduced engine power case with P2138 needs a VIN check to confirm the match.
Brake Pedal Sensor Concerns Without a Dash Message
GM’s March 2023 bulletin PIT5994 says some drivers feel low or reduced engine power under acceleration with no Driver Information Center message, and an incorrect brake pedal position sensor input may be the cause.
This case differs from the others because a chevy cruze reduced engine power event can occur with no dashboard warning. The only clue may be a weaker response than expected under throttle, which is easy to attribute to traffic or load.
The PIT5994 bulletin on NHTSA is preliminary information with diagnostic tips for technicians. It lists the Cruze from 2012 to 2019 with automatic transmissions, plus the Buick Regal, Chevrolet Equinox and Malibu, and GMC Terrain, and a technician may find history codes P057B, P057C or P057E. If the engine computer reads the brake as applied when it is not, power can drop. The bulletin says turning off traction control or performing a brake pedal position learn can temporarily correct the concern, but any wiring or connection fault still has to be repaired. The Equinox is on the same bulletin, and a separate guide covers Chevy Equinox reduced engine power causes by model year.
What to Do When the Chevy Cruze Reduced Engine Power Message Appears
Record the conditions first, leave the codes uncleared, and have a dealer or qualified shop read stored and pending codes before anyone buys parts.
- Note the fuel level, the weather, the length of the drive, and whether the message stayed on, using the questions in the 2014 bulletin.
- Do not clear codes or disconnect the battery until the shop has recorded the history.
- Check the model year, engine, and VIN with a dealer against the table above.
- Pull over when it is safe to do so if power drops during a merge or a highway pass.
If the car has a stored code, write down its exact wording as well, and see the general reduced engine power warning guide for what the message means on any make. The bulletins match a case by its code and its recorded history, not by the dashboard message alone.
Frequently Asked Questions
Does a reduced engine power message always mean a fault?
No. The January 2015 GM bulletin says the Chevy Cruze reduced engine power message can appear with little or no noticeable loss of power and no diagnostic trouble codes. Running out of fuel is another cause the bulletin describes, so check the fuel level first.
Can I clear the message myself?
The bulletins describe disconnecting the battery for five minutes, but they are written for professional technicians, not do-it-yourselfers. A code clear can erase the history a shop needs, so record it before you reset anything.
Is there a recall for reduced engine power on the Cruze?
The June 2014 engineering information states that it is not a recall. The other documents cited here are technical bulletins and listings, so a VIN check with a dealer is the way to confirm any open recall.
Which Cruze years do these bulletins cover?
The 2014 bulletin covers 2011 to 2014 Cruze models, the 2015 bulletin covers 2012 to 2013, the 2023 brake sensor bulletin covers 2012 to 2019 automatics, and the 2017 connector bulletin covers 2018 and prior GM cars and light trucks. Newer model years are not covered by these sources.
Does Chevy Cruze reduced engine power mean the engine is damaged?
The sources do not say that. They describe intermittent no-code cases, a fuel-related case, and specific connector and sensor repairs. A shop reading the stored codes and recorded history is the only way to confirm which one applies to your car.
Do not treat the Chevy Cruze reduced engine power message as a reason to reset the car at home. Each documented case depends on a record that a code clear or a battery disconnect can erase, so a dealer or qualified shop should read the data first.
