Takata recall: I've been having an issue with my 2016 Malibu it will stop and take a few minutes to start up. While driving it will go in safety driving mode and I can't go on faster than 20 miles. I haven't had my car for a year before it start giving me problems. I didn't make it on time before my warranty expire. Right at this time I can't afford to pay to get it fix 380... after calling the dealership and spoke with the manager he stated that my car is the 3rd complaint about the same issue.

This car totally cut off on me (stalled, all power everything shut off) more than once within an hour while driving, at least 30mph on a major street. Took it to the dealership because it is still under warranty and they are telling me there is nothing they can do because they can't duplicate the issue.

Check engine light & reduced power experiences three times while driving. Poor fuel economy (since purchase of vehicle) and loss of engine oil (however not visable). Miles between oil changes and issues were 5000 and 3300 (synthetic oil - should not be low & dirty in that short period of time). Idling is very rough and cooling fans not shutting off. 35 days later - same issue - reduced power, oil level low, idling rough. Dealer found low compression, blown piston and debris causing deep scores in bore. Engine replaced. 60 days later - same issue - reduced power, idling rough, cooling fans continue to run. Replaced accelerator pedal sensor. Before leaving dealership, check engine light on, cooling fan continue to run after engine turned off. Replaced mass air flow sensor.

First time this happen I was on the freeway going around 70 mph when the check engine light when on and a massage saying engine power is reduce the car begun to shake and speed when down to around 40 mph from 70 mph in seconds, I keep accelerating but the car was not picking up any speed even though my RPM when up to 4 and 5 my car wasn't going any faster. This happen over and over again. I took the car back to the dealer first couple of times they said nothing was wrong with the car. But the issue continue now after so many times they figure out that some sensors need to be replace and also the accelerator pedal was not working. I really hope this is fix.

Engine power is reduced message popped up with check engine light while driving car down the road. Car acceleration did not work there was no power and would not go past 20 mph. Pulled into traffic and was almost ran over by another vehicle due to this problem of sudden loss of power. Went from working properly to being able to push accelerator to the floor with no response care wouldn't work. Took immediately to dealer and service department says they can reproduce the problem all they did was change the oil. I took a photo when I pulled up to Chevy service dept at peters Chevrolet in longview Texas so why can't they reproduce the problem or why didn't they hook it up and check it instead of oil change first? not happy with this safety hazard I'm now driving my children in.

I decided to lease a 2016 Malibu of February 2016. The car was great until months later I started to have problems. I was driving to school on the freeway in October 2016, when my car suddenly went into reduce speed engine. I was driving approximately 65 to 70 mph. I was in the left lane of the freeway. As I was driving my car dashboard display reduce speed engine, then immediately my car went from 70 mph to 30 mph to 20mph. I manage to get my car to the emergency lane of the freeway. The problem was fixed that following week, with complications of trying to get a rental car so I can go to work and school. 2017 October 31st, I was driving to go pick up my son from school. I was on a major street. My car went into reduce speed engine. I was driving 35 mph. My car went from 35 to 20 mph's again. I managed to pull into a near bank. Shaken up I parked my car and turn it off and then back on within five minutes. The light was still display on my dashboard. I drove to my son school. I couldn't drive over 10 mph. It normally take 10 minutes to drive to my son school it 25. It took even longer to get back home. November 30th, same problem happen again. While driving on a major highway. Once again I was in the left lane driving the reduce speed engine came on. My car slowed down. I had cars behind me honking their horns at me nearly causing a few accidents. I manage to get off the freeway. I did not want to be stuck on the freeway while it was dark. I was stranded at a nearby gas station for close to two hours. The problems I keep having with this car is dangerous. I refuse to drive a vehicle that can potentially cause me or my son our lives.

Engine auto start/stop extreme safety issue (when at standstill in drive shift position) engineering modification needed engine auto start/stop needs to have a driver detector (in seat) added to prevent the car from inadvertantly driving foward without driver in the driver seat. It is especially crucial for those new drivers not used to the fuel saving start/stop engine. It happened to me recently and I was unaware car was not in park as engine was in "auto stop position" and silent. As I got out and shut door, car started to accelerate with nobody in the car. Luckily I was fast enough to chase after it, open door, and slam on the brakes without incident. This has almost happened several times prior and needs to be addressed. I would reccomend putting some kind of chip in the driver seat which would deactivate the engine if driver seat is empty while car is in drive shift position. If not corrected the car could cause serious injury to pedestrians and bystanders. This should be implemented accross entire GM line as well as other manufacturers.

While driving on the expressway my check engine light came on with the message reduced engine power. The car slowed from 60 miles to 20 miles instantly, I panicked but was able to exit without harm. Once on the street the car would not exceed 20 mph. Almost like the transmission was pulling. I received an email from on star diagnostic stating critical issue with engine and transmission service immediately. I got to the dealer at the earliest allowed and the customer service tech told me the code showing was for the trottel and not the engine or transmission, but they would have to do a complete check. One hour later the customer service tech called for me and gave me my keys saying there is no known fix at this time for my problem and they reset the codes. If it happens again give them a call. At the time of the incident I was driving 60 mph and the mileage on my car was about 39,980.
