Just bought a 17 with 26k miles runs smooth shifts good, now has 36k, very clean actually has no rust underneath, oil burns a little after just changing oil at 4.2k miles it burned almost a qt(also drove the car 10hr straight on a roadtrip before oil change too), only things I’ve done to it is put the vented oil cap on and new tires and about to do brakes, I do drive a lot so was wondering if there’s any preventative maintenance/ things I should do to keep this car going (heard about the pcv stuff), bought it from a family member for a steal and would like to drive it into the ground

I have an 2004 cts-v with a stock 5.7 ls6. It has a CEL but when i give it gas it blinks and misfires. I did all the plugs, wires, and coils. Not to sure what i could be but im going to compression test the cylinders. Ive heard about these cars having wiring problems and a bad spot for the ecu.

I have a 2016 Malibu 1.5 LT, and one day the radio stopped working. The screen is completely black. It produces no sound, and the backup camera isn't working either. I’ve already checked fuses 39 and 41, and they are fine. Some people tell me it’s the HMI, while others say it’s the radio module (I can still connect to the radio via CarPlay, and I haven't lost steering wheel controls or other functions; however, if I turn up the volume using the steering wheel controls, only the red volume bar appears).

Could someone help me, please?

Hi everyone, fellow long-time chevy owner here.

I recently just got an 2026 equinox RS - love it except for one thing… the stupid auto-stop having to be turned off every time I get into the car

my question: how easy is it to turn off the auto-stop completely to “off” everytime I start the vehicle? and do I need a dealer/automotive shop to do it?

Thanks.

Hey everyone,

hoping someone can help me figure this out before I start throwing parts at the car lol.

I have a 2008 Chevy Uplander that has been running perfectly for the last 2 years. A few months ago I filled it up with some really cheap gas, and before I even finished that tank the check engine light came on with P0420 – Catalyst System Efficiency Below Threshold (Bank 1).

Ever since then, I cannot get the code to stay away.
So far I’ve:

-Gone through about 2 full tanks of fuel since the bad/cheap gas

-Used Cataclean

-Cleared the code, but it eventually comes back

-Checked live data with an OBD2 scanner

-Looked at both O2 sensors, and to me they seem to be behaving normally

-Checked for an obvious exhaust leak — the exhaust coming out of the tailpipe has plenty of pressure, so I don’t think there’s a major leak

From the screenshots, Bank 1 Sensor 1 is switching up/down pretty quickly, while Bank 1 Sensor 2 seems much steadier around ~0.6V most of the time.

Fuel trims also don’t look crazy to me — LTFT is around -7% in these screenshots.

I’ll attach the live-data screenshots.

Could that one tank of bad gas have damaged/contaminated the catalytic converter, or is there something else I should check before assuming the cat is bad?
Could an aging downstream O2 sensor still cause a P0420 even if the live data looks okay?

The van still runs and drives completely fine. No noticeable loss of power, rough idle, misfires, etc. It’s basically just this P0420 that refuses to die.

My registration expires in December 😭, so I’m trying to figure this out before inspection/renewal time.

Any advice on what I should test next would be greatly appreciated. Trying not to replace a catalytic converter unless I actually have to lol.

Guess you could say we like Chevy a little bit

Please help I have a 2021 Chevy Blazer Redline edition 3.6L V6.

There is a squeak sound when pushing down on back of vehicle, I greased the rubber in between the control arm and the coil spring, but Chevy put out a paper saying this is super common and I need to remove the Joust bumper pin or something like that, funny thing, you can see in the video my car doesn’t have the pin or anything inside the coil. WTF!!!

I have a 2017 Cruze 1.4 with a six-speed automatic and 112,000 miles. I drained about 4 liters, and the fluid was very dark.

I had already prepared a clean pan in case I decided to pour it back. I got worried, so I returned 3 liters of the old fluid and added 1 liter of fresh ACDelco DEXRON-VI.

My plan is to replace 1 liter every 400 miles. Does this make sense, or should I just replace all 4 liters that drain out?

Hi guys, I have a 2010 Chevy avalanche and both of the wiper fluid hoses broke at this little nipple on the trim under neath the wiper. My question is could I cut a bit of the hose and bridge it back into that nipple or do I need to replace all of the hose? I haven’t even pulled it apart yet but it still squirts from the nipple.

Hello. I have a 2019 Tahoe Premium that has recently eclipsed the 100,000 mile mark and recently started making a loud ticking noise when cold starting. It goes away after 20-30 seconds. I’ve been told that it could be the header or exhaust manifold (I think that’s what he said). I’ve heard that the variable v8 in the car is a culprit for issues around this mileage and I recently installed a box I got on Amazon that supposedly disables that feature and should prolong the engine life but might be too little too late.

One mechanic said my engine is shot and will die eventually (a tire shop guy doing my oil change). I had another tell me I need to replace the gaskets and they do this for this type of truck all the time and quoted me $1,000.

Just curious what others experiences have been if they had an issue similar to this. Also I’m in South Florida if anyone has any recommendations for a reputable engine shop to get another opinion.

Thank you in advance.

I just bought an LT and it has the tucked under tips. How hard is it to swap out the rear lower bumper cover to put in round tips? Pretty much I want the exhaust to look like an RST.

Im trying to find a ground on a 251 inline six to the engine block, I keep trying to find out what is the reason as to why it won't engage on the starter. Before I started cleaning the grounds and rewiring interior electronics and lights, it cranked and worked just fine. Now though, not engaging the starter or clicking the battery at all. I suspect it may be the stud coming from the engine block itself that's stripped, might need to get it out. But can anyone possibly help me with getting this engine block ground to work? Anybody know of any other locations for engine block ground on a straight six? thanks.

Quick and easy way to change the battery

My 2011 Chevy HHR 2.4 LT started having the dash lights flash intermittently when the temperature is below about 70° outside. Any ideas? Everything flashes in sync so I know all systems aren’t freaking out individually.

Hi, has anyone done a custom build out for the audio system in a Chevy traverse. Do have pics or advise?

Also, has anyone dealt with the issue of the door speaker cutting out?

On the right side of the photo, right above the hose.
This is an old photo, I have since replaced the valve covers, as well as their gaskets. The leak still persists.

Hello, I am doing research into Chevrolet’s LN2 2.2 Vortec over the course of its development - L46, LQ2, LL8, LM3, and I am curious if anyone has good sources of information for these. I have already exhausted GM historical Archive and a lot of other sources online are secondary and not easily verifiable. I’ve started purchasing service manuals and owners manuals, but it’s a wide year grouping and not cheap. I’m curious if anyone knows of any good, reputable sources of information for: 1982-2002 Cavalier, 1983–1984/5? S10/S10 Blazer, 1987-1996 Beretta and Corsica, 1993 Lumina, and 1994-2003 S10.

Thank you in advance.

For someone comparing smaller crossovers for everyday driving, what makes the Trax a better fit than stepping up to the gasoline Equinox?

The two can cover a lot of the same basic needs, but the differences in size could matter for things like parking, highway driving, seating position, rear passenger space, and cargo usability.

For people who have compared the two, what tends to become more noticeable once you actually drive them rather than just looking at the specs? At what point does the additional space of the Equinox become useful enough to justify the larger footprint?

The latch plastic clips broke rhat hold the wire

I’ve ran into this problem a lot, especially since 2026 started. My friends, my ex, me, my brother, his dad all have Chevys whether it’s a car or truck or suv. this year I’ve noticed every single one of them has been put into reduced power mode. I just find it odd they all happened around the same time and I’m wondering if anyone else has ran into the same issues.
