To Whom It May Concern, I am writing to report a serious issue concerning the recall history of my vehicle and to request an investigation into what appears to be unresolved and inaccurately closed recalls. Vehicle Information: •Make/Model/Year: 2018 Chevy Malibu hybrid •Date of Purchase: 2018 (I have been the sole owner since) Several safety recalls were previously listed for my vehicle on your website and through the manufacturer, but I recently checked again and now it states there are zero open recalls. I have never had these recalls repaired, and no dealership has performed or contacted me regarding these repairs. Furthermore, my vehicle is currently displaying check engine lights related to the same issues previously associated with the recalls. This suggests the issues were never addressed, yet they no longer appear in the recall system. I am concerned that: •These recalls may have been falsely marked as “completed” •There may be an internal data error causing safety risks to be hidden •I am being denied free repairs due to incorrect closure of these recalls Please investigate this matter as I believe it affects not only my vehicle but possibly others. I can provide any documents, error codes, or additional details upon request. Thank you for your time and attention to this urgent safety concern. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The check engine light came on and we brought it to the shop where they said the code is for the electronic brake system modulator. It is also causing the ABS to malfunction and be hypersensitive. There is a recall for the same make/model/year of vehicle, except the month before her car was manufactured. I believe this is a safety issue that needs to be looked into and that her car should also be a part of this recall. We purchased the car in mid November and the engine light showed up a couple weeks later. I contacted GM who said to contact this site to request further investigation for safety risks.

Shift to park message comes up when driving and car turns off. Also check engine light comes on for code hybrid/EV powertain control module. The car was towed to a dealership and has been in service for 3 weeks and they can't figure out problem. I did pick car up once due to not being able to diagnosis problem and check engine light with same code and shift to park message came on hours later and took it back next day.

As I was driving with cruise control on a freeway at 70 mph the car suddenly displayed a warning to reduce speed. I continued to try to get to the next exit but almost instantly it started reducing my power and slowed me down to a crawl. I pulled over on the freeway and it would not restart. The tow truck to it to a chevy dealer and the next morning they called asking for details as the car started right up and they drove it around for 10 minutes without issue. They kept the vehicle all day but were unable to recreate the problem so they told me there was nothing they could do. They pulled 17 codes and said that's too many to diagnose so nothing to do. I drove 15 miles home with no issues. The next day I went to get the oil changed and they tested the 12V battery and told me it failed. I went to buy a battery and drove home. The next day I drove around 10 miles and then it dies again as I was slowing down to a stoplight. I pushed it to a parking lot and installed the new battery. I took the old battery back to the store to get my core deposit back and asked them to test it. They said it tested fine but I went ahead and gave it to them as I already had the new battery installed and it's a pain in the rear to do. On the 3 mile trip home they car jerked/slipped shifting briefly and the check engine light came on. OnStar sent me a notification the first time telling me the battery was drained and I needed to charge it. The second time I received a notification that there was an issue with the "electronic drivetrain" and needed to take it in for service. I'm taking it to the dealer I purchased it from tomorrow to see if they can figure it out.

Engine lost power on interstate highway. While this did not result in a crash/ rear end collision, the potential for such injury seems high. 1-2 days prior there were some warning lights (check engine light). Called a dealership Tuesday morning and earliest service appointment was in one week but they assured me that the car was drivable in the meantime. On Wednesday afternoon my son was driving on the interstate and there was a new message “engine power reduced”, and a sudden loss of power. Eventually got the car to nearest Chevrolet dealership. Their technician took over a week to figure out what was wrong; eventually they replaced the ECM but still had problems. After a software update to ECM the problem finally appears to be resolved. Please note that similar problem has been reported with other Malibu models, but my Malibu Hybrid was not recalled. Please consider a recall of all GMmodels similar to the Malibu

I purchased a 2017 chevrolet malibu as I am a salesman and on the road all day. My reduce engine light continues to come on. The car is not even 2 years old. I was advised it can be the throttle position sensor or throttle body. I have seen many complaints on line fopr the same car. Why is a brand new car having this issue?. I was on the highway and redused speeds to 20 MPH and almost caused a major accident. I continually need to pull over and turn off car top reset itself. Please let me know why this has not been recalled with so many complaints.

Coming off the hwy my vehicle slowed down from 55 MPH to about 40 MPH fairly fast thankfully no one was behind me. Check engine light came on, tried pressing on the pedals but vehicle was not speeding up at all. The traction light also came up. Took it to chevy dealer right away and they said it was the accelerator sensor not communicating with the system. Took about a week to get my car back from the dealership.

5/4/2018 took the car to service a check engine light. They reprogramed the hybrid powertrain control module 2 - per a factory service bulletin but it did not fix the problem, light came back on. 5/26/2018 - 100 degrees. Car shut down while driving straight at 40 MPH on city street. Restarted in some kind of default mode without EV components after 30 min. Next day it worked fine. 8/12/2018 - 86 degrees. Car shut down while driving straight on city street going 30mph. Restarted and drove fine but later the same day after starting the car and shifting to reverse the car moved forward, car was in EV mode. Shifted to neutral and car still moved forward, still in EV mode. Shifted to reverse and neutral again the car still moved forward, still in EV mode. Turned off engine, restarted and worked fine, still in EV mode. 8/16/2018 - 85 degrees. Car shut down while driving, restarted and worked. But later that day I started the car and shifted into reverse and the car moved forward, car in EV mode. I shifted to neutral but at the same moment the engine started and I felt and heard a shifting noise and the car worked fine. 2nd appointment will dealer on 8/20/16, appears a common factor is warm days when I park the car outside in the sun. No matter what the problem may be there is a serious and potentially deadly symptom of a problem with my car and could become a common problem. The next step the dealer will do is replace a wiring harness, again per a service bulletin so the manufacturer does know of a problem.

Driving home, turned off highway, car stopped a few feet onto side road--no brakes, steering, nothing. The icon for the check engine came on and stayed on.(manual says it is the malfunction indicator lamp.) turned car off and tried to restart to put car in drive. No luck.; called for a tow. Waited almost 2 hours. Towed home. This was in the evening. Presently waiting for another tow to a chevy dealership, the following day in the afternoon.
