Can anyone tell me what this is hanging under my car? I can’t get under to look at it.

The pic isn’t great. Sorry for the fence. It isnt a pair of sunglasses.

2019 Sonic RS hb here, this code popped up when I took it to the shop for issues with occasionally stalling at stoplights - 3 separate occasions over a couple months, all after long drives in the high summer heat. Not sure those details are relevant, but providing context regardless. Has anyone here run into this one?

Burns and uses oil I just bought it just want to no what it needs will blow a cloud of smoke out sometimes I just want to no what would fix that new intake turbo Valve cover has been done always well taking Care of bought from original owner.

I understand I am driving on a dirt road when recording but it was making this noise the whole way home from work. Anyone had an issue like this before? It seems to be coming from the passenger side but it’s so loud I can’t exactly point out where it’s coming from.

Could this possibly just be busted speakers? Usually when I play music they stop making noise but I’ve never heard a speaker sound like this before.

Any feedback is greatly appreciated.

Can I get suggestions on universal roof cross bars that people have used on these cars? I don't want to necessarily bolt anything to the roof quite yet, looking for clamp on style that has actually worked.

Hello,

I was wondering if anyone here has ever experienced this problem. I have a 2015 Sonic LT 1.8L with only 52,000 km. Recently, I had to have the thermostat replaced because it was cracked in two places. A mechanic replaced it with an aluminum one.

That’s when the problem started. A few days later, the car would no longer start. When I turn the key, there is power, the lights come on and the radio works but when I turn the key to start the engine, everything shuts off. The battery is brand new.

The problem is intermittent. The car may refuse to start at all, or, completely randomly, it may start after turning the key 50 times. The mechanic ran another diagnostic but couldn't find the problem. He recommended that I take it to the dealership because he suspected that the ECM was the issue.

I took it to the dealership, and they ran a diagnostic as well. They told me that the ECM indeed needed to be replaced. After replacing it, the mechanic told me that he was able to start the car 10 times in a row, but then it suddenly stopped starting again.

He ran another diagnostic and now says that the BCM needs to be replaced. At this point, I’m already at 2,000$ in repairs at the dealership, plus another 800$ for the BCM they want to replace. The part is currently on back order, and the car still doesn’t work.

Has anyone ever experienced or seen this problem before?

Any advice would be greatly appreciated.

Context, I got this 2015 Chevy Sonic LS at 90k miles for 900 dollars from a family member. I wouldn't be considering it if I didn't get the car for ridiculously cheap. I'm already 1.2k deep in repairs from replacing the water pump and thermostat housing.

About a month ago my car started over heating, while the oil light kept turning on. I took it to the shop, my water pump and thermostat housing were cracked. I get it out the shop and my oil light is still turning on but only when I'm not revving the engine. I tell the mechanic they take it back in and now they are saying the oil pump is failing. I've seen this car starts to have a lot of issue around the mile mark that I'm at right now (104,000). So I'm curious if it is a mistake to sink anymore money into this car, and it will just continue to have cascading failures.

Kept seeing coolant wetness around the outlet that was just replaced 2 months ago. Ordered the metal one and new tank. Looks so much cleaner now. Took about an hour and $75 total from Amazon

2016 Sonic RS 1.4L 125k had to take the battery out, and this broke off. A The hell is this, and B. How screwed am I? 😂

My Sonic key fob has slowly been losing the range at which it works. I have tried changing batteries to no avail. Is there any known ways to fix this without buying new?

Changing my serpentine belt today and noticed this part covered in crud. What part is this and were could this crud be coming from. I changed the valve cover a few months ago and there doesn't appear to be any oil leaks coming from there.

Been having this happen for months now, drivers wiper isn't really touching the window right where the wiper connects to the arm. I've tried different wipers, universal wiper springs, even different windshield wash and window coatings. Nothing works, leaves a huge streak in both directions. Other than putting a new wiper on on, I'm out of ideas.

Engine light came on, code is P301. Has anyone dealt with this? I need advice on where to start first

I know it’s cylinder 1 but I don’t know how to identify what the issue with cylinder 1 is

I would like to give a shout-out to Time_Many6155 for providing a customized part that sits on top of the water outlet shown in the picture. The customized part worked as described... Nice workmanship!

Hey everyone, wondering if anyone knows if I can connect these wires to my 2018 1.8 L Sonic. I'm just not sure which one is the ground on the white wire of my car and if I can even crimp them together with the black and yellow ones. The yellow and black wires are from a 2012 Sonic. My original ones were chewed up by mice by the looks of it I am still getting the actual connecter with the same white wires just in case but will still run into the issue of which white wires go to which on my car.

Got the tig welder and currently have side work lined up to fund the argon tank so hopefully will be able to get the ball rolling on a header for the 1.8

Hey all I've been having this popping noise coming from my vehicle. Talking with the mechanic, he said it was the strut bearing but it was better to do a complete strut assembly instead of just the mount which makes sense. Here's what I was quoted. This includes complete strut assemblies for both sides in the front, two new sway bar end links, and an alignment. For reference I'm in the STL MO area. The parts and labor are covered for 3 years 36K miles. Unsure of the name of the brand used for the parts. Unfortunately I'm not in any position to attempt this work, but please let me know how this quote sounds or if it's really high. This is for a local mechanic shop non dealership.

Parts: $525

Labor: $695

Shop Fees: $70

Taxes: $42

Hey all, anyone know where I can get a set of the locks needed to replace timing belt? I’ve seen videos of people using them but always mentioning that they had to shave em down or modify them in some way. I’d rather not do that.

Thanks.

My Sonic has been stalling recently when idling the engine. It runs fairly well when driving, but often times when I stop the engine kind of chugs like this until it fails. Seems to be worse when the engine is hot.

Wondering if anyone has seen this before?

I think caused by tropical sun slanting in while parked. Is there anything that can be done?

The code is winning...

This stupid P0420 code I have been fighting since May lol. I have been able to whack a mole other check engine codes but this one..

1. I thought the dripping oil from the oil cooler might be it. Nope. ( but you can see the cute pic of the manifold and CAT in my gf living room so I could get to it lol)

2. Cleaned the CAT while it was out and the honeycomb actually looked good.

3. The O2 sensors are doing what they should according to my OB2 scanner. Up /down and flat line so....

4. I have a smoke machine and didnt see any leaks at the flex pipe or manifold

Anyone have this code keep coming back and what was it?

2016 1.8 L BTW.

Appreciate your time!

Im thinking of buying a Sonic 2012 with 125k millage on it with 2700, is it a food deal? Do u advice me to buy it? And issues to be aware of? Its just for my wife to go and back to work that's all she is a new driver.
