Engine reduced power while driving in traffic car gets no power to accelerate and engine light also on.

- Milwaukee, WI, USA

Error message reads "Engine Power Reduced". I was on the highway and suddenly the engine gives out and only lets me go to a max capacity of 20 mph. I able to safely remove myself to the side of the freeway. A week later without moving my vehicle I checked to see the status of my car and the error message removed itself. It's been over a year now with my engine power coming and going, just as fast as it comes, it goes-- making driving very unreliable and unsafe to step onto the road.

In 2019 I took my vehicle under warranty to the purchasing dealership to fix a "shift to park" reading after the vehicle is parked. It precludes turning off the car. Repeatedly restarting the car and shifting to park and/or jiggling the controller in park usually stopped the reading. The dealer replaced the control shifter, which fixed the problem for many years. This August, the problem started recurring and I have been attempting to make an appointment in the last week, but none of the local dealers say they can repair this for some time. Most cannot even diagnose the problem for a week or two.

I-??ve paid for the repair once at about $500 and it-??s doing it again.it-??s clearly an issue because many people have put complaints in and the dealerships are seeing it frequently.

2017 Chevy Malibu has P2138 showing up.. I was on the highway loss half the power to my car, almost causing a major accident, went from 65 mph to 30mph in seconds.. This is a safety issue & needs to be address ASAP!! I have my vehicle at the dealership, the service teams seems to have no clue that there is an issue with the mailbu's !! The P2138 is defined as -??Throttle/Pedal Position Sensor/Switch -??D-??/-??E-?? Voltage Correlation.-?? It is triggered when the vehicle's Engine Control Module (ECM) detects that the signals from the two throttle position sensors or the two accelerator pedal position sensors don't correlate.

When parking car we place the shifter in park, and psh the button to turn off car it states to -??Put shifter in Park-?? after wiggling the shifter that is clearly in park the car will shut off. Also the breaks will pulsate at slower speeds like the ABS is kicking in, but is not the case. Along with the pulsating there are loud thumping noises. Car today when driving did same thing the said -??reducing engine power-?? almost made it home then completely died on me in middle of road. Was told it could be because of bad vacuum pump, brake booster sensor, and brake booster by my mechanic. He said in newer cars this would prevent the car from starting.

When the vehicle is in park and you try to turn it off with the start/stop button an on dash error code of -??Shift to Park-?? appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. I am very concerned this could cause major safety issues! When I searched for it, it appears a lot of GM owners are having the same issue. Please issue a recall!

- Muse, OK, USA

Driving vehicle like normal and then the check engine light comes on with the stabilitrak light, and get message "reduced engine power". Car goes down to less than 50 miles per hour and is struggling to go must faster while I am on the freeway. The RPMs keep going higher and higher even though the car is not going very fast. Get home and let it rest. Keep having same issue on and off past two weeks. Sometimes it comes on and goes off, has been on past three days acting the same way. Check engine light says Pedal Sensor issue. Known recall for it listed with letter sent out in 2019, but of course this was only if you were having the issue at the time (which I didn't) and it is only covering for cars under 150K miles. My car has 192K miles, so they will no longer cover it, even though it is a known issue has been for some time now! It is very expensive and unfortunate that they will not cover this issue regardless of miles, knowing that this can happen to the 2017 Chevy Malibu's at any time. Still driving it the way it is. Did try to clean out the Throttle body and see if that helped, but issue still is there. Will try to replace sensor at some point and see what happens.

- Houston, TX, USA

Engine light came on along with decreased engine power light. Felt the transmission downshifting. Speed went from 50 down to 20 while on an expressway and I had to pull off the road and shut it down. Waited awhile, turned it back on and it continued several times to downshift. Took it to the dealer, had to wait a few weeks for the part and the accelerator pedal sensor needed to be replaced. Thank god I was not in the passing lane or there would 've been a very bad accident.
