Chevy Malibu 2016 eco boost HELP!!!

The video is NOT my vehicle however is this is the exact sound it’s making, it continues while accelerating thru first and second gear and mellows out as I drive, no check engine light, newer turbo, it is not the air intake , verified by mechanic. They think it’s the turbo (possibly) , 2 other mechanics say it is not the turbo. Any ideas?

Good afternoon, I hope someone can help me. I have a 2004 Malibu V6 3.5L that has a problem where, when it’s running, it vibrates a lot and there are small explosions/backfires coming from the exhaust.

Originally, it had the bank 2 catalytic converter (front) broken, so it was replaced. After starting it, it threw a P0300 trouble code. The coils, wires, spark plugs, crankshaft sensor, and camshaft sensor were replaced. A short in the wiring for the bank 1 sensor 1 oxygen sensor was repaired. The injectors were professionally cleaned. The timing chain was replaced because it was stretched and the tensioner was broken. The plenum gaskets were also replaced.

Right now, it starts with vibration and backfires, but there are no trouble codes showing. Any ideas are welcome — I’m already out of them. (Compression was also checked and it’s good.)

2016 Chevy Malibu Hybrid problem

All the way back in November my Malibu cut off while I was driving. It gave a warning on the dash of reduced engine power, it gave a shift to park error and then a collection of lights on my dash went on then flickered off. My car stuttered to a stop while I was going about 40mph, but it did this very quickly. I did not have much time to pull to the side of the road.

Then it would not turn back on. I tried a few times, every time I tried it turned on for less time before it just wouldn’t turn on. I thought it was a battery issue so a friend tried to help me jump it. It did not work at all so I had it towed.

The repair shop fixed the electrical wiring harness which got it to turn back on fine. They said there was a problem with the acceleration and did a full transmission assembly. This took about a month.

They gave it back and it worked fine for a few days. Then one morning just as I left to go to work it had serious problems accelerating. It was super unresponsive and would not accelerate very fast when it did. I quickly turned around and was able to get it home.

I had it towed back to the repair place as it’s under warranty. They said there is a problem with the transmission and said they warrantied the part. This took a couple months for them to get it and then try. Then they told me the replacement part is also having problems. Now they aren’t giving me a concrete date for when I can expect it to be fixed. They gave me some hopefully and maybes, but it has now been almost 5 months.

I called a local Chevy dealership who told me if it’s a transmission issue it could take months as the parts I would need are back ordered. They referred me to another shop in case I wanted to have the car looked at to see if there is possibly something else going wrong.

Has anyone ever had something similar happen to their Malibu? Or would anyone have any advice on what to do next? At this point I am just playing a waiting game which I don’t feel great about.

Hello,

I am experiencing the check engine code P1101 on my 2017 Malibu 1.5 LT.

I have already attempted the following troubleshooting steps:

  1. Changed the air filter.

  2. Replaced the MAF sensor.

  3. Cleaned the throttle body.

  4. Replaced the PCV valves.

The code persists, and I would appreciate any assistance or guidance you could offer to continue troubleshooting this issue.

Extra information:

- MAF sensor 2.4 g/s

- I noticed air coming out from the dipstick oil whole

I just picked up a 2023 1LT Malibu and the low beams are terrible. Looking to upgrade to LED but the videos I’ve seen on how to change the bulbs, seem like it’s only for the high beams. Removing the air filter box and fuse box are inevitable due to the space and my fat hands.

Wondering what LEDs you’ve used that fit inside the dust caps.
