172k on my G6 and she's still rocking. Had the BCM connector issue as well as the turn signal issue. Total about $40 bucks spent on the fixes. I'm gonna drive this thing until the wheels fall off lol

i have an 07 G6 and it’s needed a few repairs but all under $900 but 160k miles later and 18 years and it’s still going strong and love it

I bought an 06 G6 3 years ago with 30,000 miles!!! It was super low mileage and I love it, I’ve taken super good care of it and I’ve only had to replace the turn signal switch but it only took 15minutes! It’s a great car!

My first car was a G6. I did not take good care of it and that vehicle gave me nothing but love. I miss the Duchess

I can't believe you guys didn't go over the oil leaks. Intake gaskets, oil filter adaptor, oil pan. 😆 you guys took the easy way out

Only thing that I would add is the headlights. The cheap wiring breaks and one or both lights go out... intermittently. You need to go buy the pigtails and solder the new ones in.

Forgot the lower control arms and sway bar links they wear out quick

2:10 I actually love that it doesn't automatically get rid of the turn signal because sometimes in other cars it removes too quickly and with the g6 I have control on when to get rid of the signal.

This video proves there are good ppl out there posting accurate helpful information because the BCM thing was my problem and this worked

my 2005 pontiac g6 has had every single one of these problems minus the turn signal switch. great car tho. 330k miles and still going! also the electrical steering going out was fixed for free at the dealer due to a recall.

Just sold my 05 G6. 200k and still running like a champ. Never had any issues with it. The northeast winters just had other plans with the body!

Had 3 G6s in my life and i loved them all. Last one I had was a GT sedan with the panoramic sunroof which I LOVED! Had almost 300k miles on it and never had a single issue besides having to replace a wheel bearing. Have a G8 GT now but would like another G6 for winters

Melting power steering hoses: One significant issue worth noting is on G6's that have hydraulic power steering (as opposed to electric power steering). I had a G6 GT 3.5L V6. The power steering lines both run right under the rear exhaust manifold. And when I say right under I mean RIGHT under it. When the engine is under load and it tilts back, that rear exhaust manifold leans back and TOUCHES the power steering hoses. The hoses have some heat shields on them but those are worthless against the super hot exhaust. My power steering hoses melted all the way through one day and out went all my power steering fluid onto the ground. This happened while I was driving, so I lost all power steering assistance. I was able to replace the hoses and secure them down with some zip ties. This held the hoses at least a couple inches away from the exhaust, but I wish there was a better design for that. Every drive after that, I had to worry if it was about to melt again. Just something to watch out for and ask about any service history on that issue.

I have a 2006 G6 V6 3.5 and i have had to change out the blinker switch, replaced starter, replaced fuel pump, and i have had the transmission rebuilt, but my car runs great now. I love the power that my G6 has it will get up and go.

I had an 07 as my first car, I loved it. Most reliable car I've ever had. My Malibu that replaced it was junk

I've owned 2 of these sub models and when the internal voltage regulator goes out inside the ALTERNATOR, the body control module freaks out under hard acceleration and you lose power steering, in addition to the instrument panel resetting, until you remove your foot from the hard acceleration. In both cases I opted for an UPGRADED alternator instead of and OEM replacement, and have NEVER had a problem after. In severe cold whether starts, the charging voltage can be high, causing you the steering to act nervous but after a few minutes of warm up, your fine.

I feel better every time I see one of these videos. I own a 2006 Pontiac coupe and my only problem is the blinker thing. And the general problems just don't seem to be a major threat and or easy to fix

I used this video to help inform of of a 2007 G6 GT Coupe purchase 🙂 not exactly the car in the video, but certainly enough similarities to take note!

you should make it top ten cause there are plenty of issues. like the shifting linkage, the oil leaks, And The plastic heater lever under the dash that switches it from hot to cold. I have 260 thousand on mine and I do have to say the car still feels tight {like new} and runs great handles good to

My Pontiac still rolling after 14yrs 🤞🏽🙌🏽

Wow I had no idea there were two different dielectric grease products.

Really helped me out I now own two g6 and one of them is having many of these problems both of my g6 still have less than 60 k miles too!!

I have a 2010 and i really haven’t had no problems had it since 2014 it’s getting old but runs great

Consider yourself blessed

Mine has 170,000 miles, none of this has happened yet, counting my blessings, and accepting that something will happen sooner or later

G6 gt 2007 on 214k miles, so far I had a serpentine belt torn to shreds due to a/c pulley stalling, replaced exhaust system due to human error lol, replaced return line on rack and pinion due to it routing and pressing against exhaust burning a hole through it (that was a pain to fix but it was my first time), some grounding issues causing a bunch of lights on my hud, alternator going bad, o2 sensor replaced, and yeah I think more but IT STILL RUNS. Thankfully and I did it all by hand no mechanics and I ain’t even that knowledgeable on cars 👍🏼

I got my G6 handed down to me with about 120k on it, i’ve had to replace the solenoids, power steering sensor, and turn signal switch all in the last 2 years. Overall it could be worse, and it’s been a pretty reliable car!

My G6 has over 293K on the odometer and I've had to replace the front wheel hub assembly and the headlights. She could probaly use a new Catalytic converter though. I have a P0140 right now

Wow! I have several of the problems you listed. My blinker has always been wonky. My wheel bearing is howling and my power steering quit working after I slid off the road the other day. The code reader says "lost communication with power steering control."

I own an 08 G6 with 110k miles. I've already had problems with the steering intermediate shaft rusting/seizing up, coolant temp sensor, transmission speed sensor, weak timing chain guides (had to replace the whole timing chain/guides), corrosion getting inside the trunk release button, weak door lock actuators, and my all time favorite is the obnoxious popping sound coming from the poorly designed rack & pinion. Mine broke apart inside and I lost control of the steering while driving. The turn signal doesn't cancel automatically anymore, I've had problems with the VVT solenoids even after replacing them, the dealership did a half ass job fixing the power steering issues, the transmission shifts hard when the engine is cold/during winter months. I've had to replace the ball joints/control arms due to the ball joints failing. They never put grease zerks on them so there's no way to properly maintain them. Both struts had to be replaced already. The drivers side strut makes a bunch of racket, and the passenger side weld broke where the swaybar link connects to it. The speakers don't work worth a crap. The rear speakers need to be replaced, and I had to cut the speakers out of the housings and reuse the factory housings due to the design of the front door speakers. When I run the air conditioner, which is also going out, the back floor floods with water on the passenger side. That being said, the whole car smells because of it.

Im looking at an 07 with 88k miles .... Hope its desent, looks like brand new

A repeat customer came in with their recently purchased boneyard G6 for new tires, front bearings and CV axles. Lss, the end of the axle that goes in the trans was too long on the new one and it popped out of the trans at the customer's place of employment so I had to go out there yesterday with another new one of a different design and it went in real nice, snapped into place and didn't come out again. Some cars are hard to order parts for.

as well as front struts and hsad gasket which did it in.

Personal opinion but any dielectric grease on the BCM connector is better than none and even the cheap stuff will last you 4-6 months. But why aren't the front control arms mentioned? It greatly effects how the car drives once the bushings or balljoints fail. If your G6 displays faults for ESC, Traction Control, Cruise Control doesn't work, or your Brake lights don't work properly, then clean your BCM connections and apply dielectric grease and it should all go away.

I came here because my local dirt tracks (2) in a 25 km radius) has started up a new division and vast majority of cars are g6 cars. But can be any v6 sombody is selling one down the road from me so I’m trying to find out what to look for. Thanks for the video 👍👍 Take care

Tell us please the specific characteristics of “low voltage” dialectic grease. Then also define what you mean by “low voltage”....

2008 G6 4cylinder here, and it has every single one of those problems 🤦‍♂️ Is there a cheap/simple fix for the power steering?

Anybody know how to tell if a dielectric grease is low voltage or not? A search doesn't show me an answer.

Dielectric grease would NOT help or fix corrosion! It only helps prevent FUTURE corrosion. You must use electronic contact cleaner to clean the corrosion FIRST, and then apply dielectric grease to seal the contacts/plug.

234k on my g6, OG trans and motor. Few minor problems. But this has a very reliable vehicle. It has hydraulic power steering instead of electric. Only thing that has gone wrong is the turn signal, and the hub bearings aside from just general maintenance. Great vehicle and value.

Coworker had one of these and the transmission just gave up on him one day getting on the highway. It was pretty cold that day, but still come on Pontiac.

Very good and simple solutions/prevention to these 5 problems! Thank you!!!

This is a good video I just recommend describing more about the specific colons to replace for the powersteering and also the sensors other wise some good stuff I'm learning more and more with my g6

I suddenly started loosing my Power Steering today. It scary when it happens while driving.

I own the 2010 and have had to have my transmission solenoids replaced and seen it in a lot of the g6's

210,000 miles and still running like a champ

That turns signal switch problem seems to be common with GM unfortunately. I've had a Camaro and a Firebird with similar issues.

Interesting “tidbit” on low voltage electrical grease . ✅

I have a 2009 G6, when the car is in park just idling it idles rough and sometimes the RPM drops like it’s going to stall and jumps back to normal (the rough idle is still there) please help😫

My G6 just died at 205,000 very reliable up to that point

Okay awesome. How do I disconnect the BCM Connector. It’s plastic and I don’t want to break it but I cannot get it off out or unplugged. Update got the gray plastic clip loose.

I have one with 200k! So far haven't had any of these issues!! Edit: I actually am experiencing the turn signal problem. But idc I'll just turn it off manually

Been trying to find out for months why my tail lights won't work. Now I know it's the bcm. Thank you!

I've used bulb grease on that connector, and it has to be redone every couple of years. The brake lights will be on constantly and then shut off when you hit the brake.

I’m getting between 25-35 avg mpg. It has 166k and counting!

I cant believe they didnt mention ball joints. Here in NY I replace lower control arms all the time due to loose lower ball joints. Maybe it's from our bad roads?

There's a recall on that platform for the electronic power steering and that deadly ignition recall. Ion, HHR, G-series

All the issues he described here happened on my 2010 Malibu. Problem is my VIN doesn’t have the recall on the power steering issue. Got quoted $1200 to fix it. Was looking to buy a G6 to replace my Malibu. Not anymore I’m not.

I just bought an 07 with 135k miles on it, i already notice it needs new hub bearings and i already broke the blinker switch😂 Over all the car drives like a dream, its a little bit loud and the trans shifts rough but its a good car.

i replaced 6 wheel bearings in 10 years and control arm assembly

I was looking for the issues i had but they weren’t here, my car is rocking 200,000 miles and is 06

Having a problem with a 2009 g6. It won’t start. Not on account of an engine problem but an electric problem it cranks but then shuts off. While trying to start, the anti theft symbol pops up on the dash and when the key is released the car shuts off. My mechanic cleaned the points on the BCM and that worked for a few miles. It can be started again after removing the batter cables from the terminals and then putting them back on. Recently it has had new valve cover gaskets installed and there was an issue with a clogged brake line. And the starter has been replaced. What might be the problem? Thanks for any information.

Every single issue he's talked about I've had including a leaking sunroof

Wasn't there a massive recall on the electric power steering issue?

I have this car and it's like the whole left side is shaking extremely bad at time and sounds like 2 plates banging when I go to brake. What could the issue be

'07 G6 3500, here, with almost 260k miles, and aside from a tranny rebuild, been pretty reliable. I am surprised, however, that melting low-beam connectors are not in this list. I've had to replace mine twice. The second time, I used Dorman high temp sockets, which have a pigtail on the other end. That way, if they melt, I can just unplug and replace them w/out having to solder, but hopefully, the high temp sockets won't have that problem. I'm also surprised that the sunroof drain tube shrinkage problem isn't mentioned. I don't know the percentage of G6's with sunroofs, but it is a well-known issue - to the point that GM made a parts kit to extend them.

2009 pontiac g6 2.4L... My car won't accelerate well. Pushing beyond 40-50 mph and it just decelerates on its own and its bad to the point of surging down to 15-20 mph if I punch the gas. And also when I punch it, the traction control comes on and engine power reduced, warnings come on and the car will shake pretty violently when I come to a stop. I shut my car off for a min and the warnings go away when I crank her back up. And I can go back to my cautious driving... I've had 2 "cam phasers" (VVT) changed out. Fuel pump replaced. Vent valve solenoid replaced by the tank. And taken the cat converter out and cleaned. When the cat converter got cleaned. It seemed like it was semi fixed. The check eng light was out for all of 10 mins so I didn't dare push her too hard. But I could at least get on the freeway again. After 3 or 4 weeks, I just felt a difference in the power, but she was still doing her better performance. I put some cataclean in there. Maybe a day or 2 later and it's back to it's old ways. Can't drive on the freeway at all. Can't accelerate worth a crap. I turn her off and crank her back up every 3 or 4 red lights and she seems to do her normal version of bad, until I go up a hill, and she bogs down and won't allow for acceleration until the hill is behind us.... What else can be changed? What am I missing. Why does she do better with turning off and cranking up? Any suggestions or insight or input is welcome.... Trying not to get have to get another car... And trying my damnedest to keep "Pontisha", that's what I call her, as long as possible. But I'm at my wits end.

Mine won't start unless I wiggle the wiring harness right below the BCM connector. Why? Square red one plugged to the fuse box. Will unplugging it and putting that grease stuff you said on it fix it. Or does something need replaced. Already changed battery and starter. Thought that was it but still when it doesn't start I just wiggle and it starts. Milage dissapears when it doesn't start and lights on dash light up. Remote start doesn't work anymore either not sure if it's related or not

Could you guys make a video on how to replace a window spray nozzle on the Pontiac g6

I love my g6. I have had everyone of these issue's 😂 power steering was costly.. still cruising at 215k miles..

The impossible to reach without taking a crap ton of stuff off and good luck finding it if you drop it... shift linkage bushing. POAS bushing thats nearly impossibly to do with just your hands and common tools.

I have 2 of the 5 problems you listed, I have the 3.5 Engine. I had to change the Water pump twice.

The rocker panels rust out to I see dozens of them driving around that look terrible lol

Hows these cars at high mileage ?, I just bought one that has 165K but runs alike a champ !

Yay! I have a G6!!

What brand do you recommend for the low voltage dielectric grease. I am having trouble finding low voltage. What should I buy?

I believe my BCM maybe going, when the vehicle starts sometimes I'll have no power steering and the airbag light will come on and go off intermittently, none of these problems are consistently on.

I have 2007 g6 and i am having problems. Shifting its slow or won't move out the second gear or third. One time i didn't take my feet off the petal and it finally shift to the next gear. Is VVT solenoid my problem? I have headlights problems replace the bulb so many time.

Engine light keeps flashing when I accelerate

VVT solenoids here, check light comes on and off. Bank 1 code P0011. 3.5 v6 so the intake, belt, and water pump will need to come off to install. Also loud whistling from underneath exhaust when accelerating past 2 rpm’s, hope it’s a simple gasket fix

Hey I have a 2006 g6 gtp. I’m currently getting the door lock and unlock going crazy when I take it out of park. But as soon as it goes back in park they stop going crazy. Then it also won’t shift passed 3rd. Even when I stick it in slapstick to try and shift out of 3rd I get an error on the dash where the gears are displayed. As well as a crazy idle. Also, my cluster gauges move up and down like crazy when driving.

My trunk button and mirror adjustment buttons don't work, is this because of the BCM? 220K miles and still chugging. I have the turn signal and solenoid issue

Electrical issues with the headlights nonstop for 5 or 6 years. One side has new pigtail replaced and still. Wheel bearings have been replaced twice in 3 years in the front.

I hit a deer in November, did not know that the radiator was cracked- and drove all winter with basically no radiator fluid. Noticed it in like May, had it fixed. Still running like nothing happened.

Thanks for the info I’m currently drive the o7 g6, and my main problem is my gas cap and maybe new suspension because little bumps in the road make it rattle quite loud and excessive

Is the steering column sensor issue a replace and wait for it to go out again or is there a more permitted fix for this problem? That sensor was replaced under warranty from Pontiac and it has failed again.

Hi I saw your video very interesting. Can you tell me where is located the coolant sensor code P128 for the Pontiac G6 2008 most appreciated

Looking for a video on replacement of the RCDLR. Is this soemthing that you have covered. Thanks

Another big one is the Low Beam Headlight connector terminal corrosion that melts the lamp connector terminal. If you know how to do electrical repairs, then pigtails and dielectric grease from parts stores will only cost about $20. If you take it to a dealership, they will be required to sell you an entire front lamp harness ($$hundreds$$) , because they aren't allowed to modify a safety system. That won't solve the problem either, because it will just fail again.

Mine has all of those problems and a whole lot more.

Headlight Wiring melts. I got a wiring from a junkyard and bought 35w leds from Amazon, instead of 55w bulbs. No problems after that.

❤ I love Pontiac G6V6 🚘😊

I am having trouble with front and rear running lights I will try fixing the connector as you say

Out of the 5, I had one. I replaced my VVT Solenoids @ 211,XXX miles

Paid 1000$ for no rust southern G6 installed some new parts in the front and rear and it’s been the most reliable little commuter car you could ask for.

My turn signal doesn’t shut off when I turn but you didn’t give the solution did you? Can you do a video on the convertible pretty please? Mine worked fine but now I’m getting a “check cargo top” message when I’m trying to get the top down.. Check cargo top where and how?

I have the turn signal problem in my G6, if I just buy a new turn signal knob will it fix the problem?

How do you relearn the throttle on 2009 Pontiac g6

2005 and replaced starter and it starts up,will go a few blocks then dies. Battery is fine. Do I need a alternator?
