I've got 165k on my 2012 turbo and last year my transmission ate itself with the bad bearing issue. Had it replaced with a 77k mile trans and had a new slave cylinder put in+clutch. Its been fine for like 15k miles and now I'm having clutch pressure issues. Variably soft clutch pedal, worse when...

My 2012 sonic lt has 165k on the original suspension and I think a strut is blown up front making noise. Time for new ones. I want noise free, and I want a comfortable ride. I have a sports car I don’t really need another. Loaded struts, “quickstruts” is what I’d prefer. But all I can find are...

I bought my Sonic new and 1 of the big regrets was not getting it with fog lamps. I've seen aftermarket kits, but they require an aftermarket button. Any way to wire in the lamps and the stock switch?

My car has 150k on it but I want to get a trifecta tune for it. Good or bad idea? I just changed the oil feed line for the turbo. The engine doesn't seem to have any problems. Maybe a bit of timing chain rattle when I first start it in cold weather. What about the tune? Does it get me to...

On my 6-speed manual the transmission started the notorious whining around 100k miles. Its now @ 150k miles, and in the past 1000 miles it started having a noise I thought was a wheel bearing. I got the wheel bearing replaced, its not a wheel bearing but a similar growling noise. Appears to come...

I need to replace this hose, it just started leaking today. I can't seem to find a diagram that can give me a part number. 2012 1.4L turbo, it goes between the water outlet and turbo.

Waterpump design seems bad on these cars, I just had mine go bad for the 3rd time in 130k miles. Last time was @ 90k and was covered by the extended coverage from GM. This time, no such luck. Am I wrong for just getting the cheapest waterpump from O'Reillys? Or are there better options from...

Yesterday I was driving in a downpour and hit a few deep puddles. After 1 of them the a/c quit working. Feels like the a/c compressor isn't turning on. When I drove back home, it was odd that when I pulled into my garage the radiator fan was running full blast. Didn't have the a/c on then (or...

2012 Chevy Sonic 1.4L 6-speed manual with 125k miles. In the past month or so its developed a squealing noise on the passenger side of the engine. No trouble codes so far and if I pull the dipstick the noise doesn't go away. Had a fresh valve cover and intake manifold put on last year so I don't...

In the past week I've suddenly noticed a grinding noise coming from the passenger drum. It only happens when using the brakes, and only if I've been braking hard, like in traffic and the brakes are hot. Its not a constant noise, sounds like its a certain spot as it rotates? If I use the e-brake...

I broke the clip off the connector for the ignition coil, will it stay on without it? It seems like its snug on its own? I pulled the orange locking piece out, and depressed the black tab and the connector wouldn't budge. Tried to pry with 1 screwdriver and it wouldn't come off. Used 2...

Engine's making a ticking noise coming from the drivers side of the engine, over by the throttle body? It goes away when you rev it/with RPM but happens a bit at idle and gets worse the longer it idles. It also idles rough when it does this. I've noticed over the past month or so it stumbling a...

I fixed all the coolant leaks on my '12 Sonic and it was good for a couple weeks. Then I noticed while parking it in the garage that there's now coolant steam coming from behind the driver's side headlamp. Literally coming from the gap in the bracket behind it. A coolant hose connects to the...

I just received a letter from GM today saying they're offering special coverage on my 2012 Sonic. Supposed to cover the pcv/valve cover to 10 years/120,000 miles. Also includes reimbursement. Anyone else get this letter? Anyone use this special coverage yet? I just replaced valve cover and...

I just stumbled upon DDMWorks' silicone hose kit for the 1.4. Is it worth it? Do the hoses last longer? I just replaced the coolant reservoir in my '12 Sonic 1.4 because it had leaking hairline cracks in the bottom of it. Now its dripping from the big hose that connects to the reservoir, and...

Anyone know what the plastic piece is that's in the top of the water outlet? I can't find a parts diagram that names it and its not sold with the water outlet. On my car its cracked and I need to replace it. It has a small hose attached to it that goes to the top of the coolant reservoir.

How do you check the pcv return valve without removing the intake?

I have a 1.4T and I recently got a code P0171, it running lean, and I think p1101. I've had this issue come up 2x before years ago and it was always the PCV on the valve cover. Sure enough this time it was hissing from the PCV. I changed the valve cover myself. Previously it was under warranty...

I'm doing the valve cover on my 1.4t and it calls for 71 inch lbs. The little inch lbs torque wrench I got only goes down to 120 inch lbs. What should I do? The RTV is drying as I speak and no places to get tools are open. Also, the write-ups and videos I saw for doing this show applying RTV...

Anyone else have their coolant reservoir leak? For 2 years now I've thought I've had a radiator leak. There's dried coolant down the drivers side of the radiator. I haven't addressed it because it hasn't gotten worse and I have to top it off only once a week. Now because of coronavirus and me...
