After stopping and shifting to park and pushing the "Ignition Button". The button indicator light shows car is not in "park". The dash indicator also states "Shift To Park" even though it is in park. This can be resolved by many pushes on the shift stick lever. It is obvious to be a shabby mechanism inside the shift box that isn't connecting the circuit to show that the vehicle is actually in park. This problem began about a week ago and it seems to be somewhat worse as time goes on. When it first happened, I did not know what to do. Thank god for google that showed me how to "jerry-rig" a fix each time to show it actually in park (flipping the shift stick button). If left alone, I would possibly drain the battery. Also google comments and post indicated this is a complaint by many and should be a considered for a recall.

When driving my vehicle at highway speed the vehicle slows down at about 15-20 mph a message on the dashboard states engine reduced power. The first time I was able to get over and cut the vehicle off and restarted it. But the vehicle did it again. The check engine light has been ever since. A few days later the vehicle did the same thing. I took it to Autozone and they gave me a code. Which is for the accelerator pedal sensor and the throttle electrical control. This is very dangerous to be driving at high speeds and all of a sudden the vehicle drops speed to 15-20 mph. I haven’t been able to find any place with the part to get the vehicle fix. Can someone help please?

When vehicle is engaged in auto stop, it stalls out completely or bucks forward when at a complete stop(sign or red light). Upon review, two mechanics stated it has to do with the transmission and tork converter. Repair is upwards of $4000-$6000. 2017 Malibu has less than 75000 miles. Will be contacting dealership today 4/10/22.

Complete loss of engine power while going 65mph on highway. Warning light of low power first followed by check engine light then power reduced to 5mph. I turn the car off then restarted after 15 minutes, the morning light was off but the check engine light remained on. I then went to AutoZone to have a diagnostic test done which resulted In error code P2138. P2138 is for throttle/pedal position. My vehicle should still be under warranty however due to short staffing I am unable to make an appointment to have it looked at for at least six weeks

My 2017 Malibu suddenly had the "check engine" light come on, and a message indicating that a "reduced power mode" had been initiated. I drove the car immediately to the local dealer, who said I needed an appointment to have it checked. I checked the OBD2 codes with my personal meter, which showed a p2138 code, indicating a problem with a throttle body sensor. When I started my car the next morning the MIL light didn't come on. At the dealer I was told they couldn't do anything with the car because the light wasn't on. I pointed out that the failure codes were stored in the ECM, but they said diagnosis wasn't possible with the light off. The service writer indicated the problem was not uncommon on GM cars and that even his wife's car had similar problems. When this occurred I was fortunate to be on a local suburban road where reduced speed was not that great of a problem. Much of the time I am on freeways in several major Midwestern cities where aggressive drivers are packed together. I read a number of complaints on the NHTSA site indicating same complaints from Malibu owners. A sudden reduction of speed in a congested area is a recipe for disaster. The service writer even stated that GM had an extended warranty on the pedal assembly and TPI sensors. But he refused to try and diagnose the issue, unless I brought the car in immediately if and when the MIL light was illuminated, even if I was 500 miles away. As this intermittent behavior is a known and common issue I feel that GM should be compelled to do something to correct these defects before a truly dangerous incident occurs, causing devastating results. But I'm sure that this will go on until misfortune causes those in power to ask. Why didn't somebody do something?

I purchased my vehicle in August of 2020, in October while driving down a main highway the engine light came on with a warning that stated "driving with reduced power". The vehicle slows to 20 mph and will not accelerate any faster. I called my dealers service center and was told this issue was a "quirk that happens" and to "turn my vehicle off and start it again" and that by doing this it would make it go away and it would not happen again. Approximately 8 months later this happened again, so I called the service department and was told that a line was freezing and that I could bring my vehicle in so they could empty & refill the frozen line costing $500, but it would not solve the problem, the dealer then recommended that I park in a heated space to avoid it freezing, but again it would not resolve the problem long term. A month later while driving home from work in a blizzard, my vehicle once again lost power, with the engine light on and a warning that I was driving with reduced power and slowing to 20mph. This put myself and other travelers on this busy main road at risk. When I reached out to my dealer they said that there was nothing they could do that would guarantee a fix, but they could try three different options, again with no guarantee of a fix. None of this is covered under warranty and costs roughly $1500.
