Possible carbon monoxide intrusion

[Doubeleive]

sounds like a convenient way to get out from under a loan to me, especially given something like that happening is relatively unheard of unless it's a ford ppv
what do you have to back up your claim? if the exhaust system is ok then I am going have to call b.s. on this one. air circulation on these truck enters from the front right side and by default air is sent inside the vehicle to the floor by your feet and exits out the back above the tail lights thru vents. co is lighter than air if it was trapped anywhere it would be near the ceiling, the rear vents are high up, chances of co being trapped inside are nill even if it was entering somehow. have you checked your home or workplace instead? are you leaving it running in the garage? nothing else makes any sense.

That’s so rude (the comment about trying to get out of a loan.) My home, my work all have CO detectors and I installed new ones as well as placed one in my car. The car CO went off. I have 3 ER visits, 3 urgent care visits, and an ambulance bill plus more and I just got the vehicle 4 months ago. I’m getting a different vehicle which means a whole new large loan for the same amount. I’ve already made principal payments to the current. That’s so silly. CO registered in my car and in my blood and it’s all documented by the urgent care, hospital, and fire department. I’m lucky to be alive. Prayers to you that you enjoy the one life you get. Mine has been put into perspective and I thank God I’m alive to hug and squeeze my babies tonight. May you never ever find yourself in this situation ever and may more joy and optimism fill your life. I’m here to warn others and clearly there are other testimonies written.

Well, this would be the first CO poisoning I have heard of in these vehicles so I’m curious as to any outcome you might share with us. Following.

I'm just calling it like I see it, post up a video, lets see some solid proof, did you report it to gm? just to the dealer? did they do anything to test for co?
a trip in the ambulance because of co in the vehicle would certainly raise some eyebrows with gm don't you think?

It’s an unfolding situation with the outcome still pending. I don’t owe you anything nor do I cater to internet arrogance. It’s stated in my previous post that that NHTSA have been informed. The dealer and myself will be working with GM.

don't forget to follow up later with what the issue turned out to be.

I agree...I think we’re all curious as to the outcome of this and would like to hear when all is said and done.

I just did a quick search on CO poisoning and found this:


“Causes
Household appliances, such as gas fires, boilers, central heating systems, water heaters, cookers, and open fires which use gas, oil, coal and wood may be possible sources of CO gas. It happens when the fuel does not burn fully.

Running a car engine in an enclosed space can cause CO poisoning.

If household appliances are well serviced and used safely, they should produce negligible quantities of CO gas. Using old appliances, and not servicing them frequently, leads to a higher risk of CO emission.

Here are some other causes of CO gas emission and buildup:

Smoking cigarettes causes blood levels of CO to rise.

• Leaving a car in a closed garage with its engine running can produce deadly amounts of CO within 10 minutes.
• Burning charcoal produces CO gas.
• Blocked flues and chimneys can stop CO from escaping.
• Fumes from certain paint removers and cleaning fluids can cause CO poisoning.

Products that contain methylene chloride (dichloromethane) should be handled with care, because methylene chloride turns into CO when it is breathed in.”

Are you sure it’s not anything else?

I’m positive it’s the vehicle. I have 4 CO sensors at home. I was bringing a portable CO sensor to work when it accidentally registered the CO in my car. I didn’t suspect my car until the sensor showed it. I thought it was my work place honestly, which had sensors already, but I was going to add my own new one. My work was actually negative with my CO sensors too as well as there own. My home is newer. We don’t use our garage for our vehicles at all. I even stuck new CO sensors in our garage, kitchen, every part of the house, etc. just to be safe. We already had existing working ones that communicate with a monitoring service. I don’t use chemicals. If I clean, it’s pretty organic stuff... soap and water, essential oils, etc.

I wasn’t sure of the source and started looking for it after a doctor suspected it. I received treatment for my elevated CO levels. They were medically recorded down to 1% the day before I got the vehicle back from the shop. I got the vehicle back, spent about 35 minutes driving in it, got the exact same symptoms (CO poisoning) again and my levels were measured while symptomatic at 8% by the fire department. I received oxygen and they came down to 6%. I went to the hospital per their recommendation for still being symptomatic and transported myself and my levels were 9% there. Treated with oxygen for about two hours and levels down to 0%. Had the car brought back to the dealer by someone else and no I haven’t had any symptoms since. Interestingly enough, the person who drove it reported a headache after.

I’ve owned this vehicle about 4 months, and my symptoms started around that time and have been ongoing since (looking back at all the doctor visits it makes sense.) I have multiple medical visits, just didn’t know why the symptoms were happening. With covid lockdown and working from home, I wasn’t driving very often.

Here’s the ppm reading I got from my car CO sensor when I wasn’t expecting it. I’m not malicious and I don’t plan to rake GM through the mud. I just want this known and to hopefully save someone’s life if the situation is ever occurring to someone else. I spent months being ill from chronic low exposure and it’s the worse thing ever.

Like you, I am in disbelief. I couldn’t understand how it was happening. I cried having to bring my vehicle back. I fell in love with this vehicle. It was everything I wanted and I’ve paid extra into principal. Now, I have to start all over again loan wise plus medical debt. I’m going to give another Chevy a chance because we own a Yukon and have never had issues with it. But, I’m happy to be alive and I pray my future health isn’t impaired.

The dealership is a great one and I fully respect them. They are going above and beyond. They are taking the matter serious and turning all their attention to try and sort out how it’s happening. It’s their vehicle now and I’m confident they will sort it out. I’m too traumatized to ever be back in it.

My mind is very scientific and that’s the type of career field I’m in. If I get answers, I will openly share with you. Thank you for all of your expertise and feedback. I’ve never had something like this happen before and my whole goal was to research, find if it happened to others, and prevent future harm to another.

After reading this thread It made me think. I commute 1.5 hrs at to times and sometimes get sleepy. So I just bought me a CO monitor to check all my cars.

I too get sleepy on my commute- oh wait that’s because I don’t sleep enough. Mystery solved!

 

[Rocket Man]

If I commuted 1.5 hrs each way I’d either be sleepy or angry all the time I’m commuting.

thanks for the post but you may want to contact a lawyer and document your issue with them and then seek compensation with gm, nobody here can help you with this. good luck sounds like you may have a case provided the vehicle has not been modified in any way.

They said the exhaust system looked ok. The vehicle has to be driven over 30 minutes for some reason when it’s happened. It’s not constantly happening. It does it on and off. I can’t figure it out, but my portable CO detector picked up CO in the cabin of the car and I became sick again and emergency department and fire department confirmed it in my blood. I can’t figure out why it’s happening. I brought the SUV back to the dealership. I’m done with it.

 

[haydennd]

NO, those would not be related at all, like Wade said the exhaust is a sealed system all the way to the tail pipe, so unless you taped a hose in the tail pipe and stuck it in your window there is pretty much no way carbon monoxide is going to enter the vehicle

Thank you. I want others to be aware that this is a real thing that really is happening before they lose their life or a loved one. I reported it to the National Highway Safety Commission Administration too. I’ve always been a Nissan owner and am new to Chevy. Not sure that I’m a fan.

Hi Leanne, I’m interested to see what’s going on with your vehicle I have a 2021 yukon XL with 14,000 miles. Just had an emergency tow that has made it to priority level for GM. For months my family has been quite ill admitted to the emergency rooms after episodes. Moments that escalated and formed into a WTF moment. The youngest 2 arepunder 19 mos. Different admissions to hospitals because of not being able to breathe heart issues high blood pressure slurred speech gut issues. July 5 I kept going off the road and struggled to maintain conscious even when out of the vehicle. July 6 it became visible.
GM is involved and “ fast tracked” it after an c
emergency tow due to the last day I drove it’s events.
The dealership it was taken to confirmed there is CO in the cabin. Multiple issues and GM is going to have it tore down. Basically there’s been a slow leak and the build up in different parts I guess shows it. Different codes fired on the vehicle and some sensors that should’ve been triggered weren’t.
The last day more exhaust was going into the cabin than out of the exhaust. Things Will pick up over the next few days but it’s been a whirlwind because the initial inability to track my vehicle to me when putting in the vin.
It pinged everywhere for the GM rep they had to add me to the system and manually put my info to the vehicle. The fact that they’re looking into whether my vehicle should’ve even been sold to me or did it “mistakenly” slip thru a time period There was definitely a shortage of these vehicles available when we bought it due to Covid and everything else. Dodge picked it up at an auction on the other side of the states got the 100,000 from me but yet wouldn’t assist in even helping find a loaner.

Have you been drinking? your comment makes no sense

Lol it’s talk text as I said 2 babies under 2. But yes gm just had their own diagnostic run and collapsed lifter had a bolt sideways. Still no vehicle but the place it was towed to found a loaner finally

a collapsed lifter does not cause carbon monoxide poisoning

I have to second this. Someone at GM is so full of the brown doo doo that is eyes are brown. There is no way some lifter is going to cause the cabin of a vehicle to develop a leak that allows carbon monoxide to get into the vehicle from the tailpipe.

 

[Tahoe2017]

I did a search and couldn't find anything on this, but has anyone had an issue with carbon monoxide getting into the passenger compartment? I inspected the exhaust system for leaks and found none. For the last couple of weeks, when I drive a distance (45 mins or so), I and my passengers get bad headaches and feel nauseous. After being out of the vehicle for an hour or two, everyone feels fine. This is the only thing I can think it might be. What say you other Yukon and Tahoe owners? Ever experience anything like this? Does anyone know where the outside air intake is for the rear heat /AC?

Thanks in advance you any help you can provide.

Hello, This is also happening to my 2017 Tahoe. I replaced all exhaust manifold gaskets, Exhaust manifold seals to Y-pipe etc etc. CO enters my cabin randomly. Have you found a solution? If so please reply

 

[Tahoe2017]

I have a 2017 Tahoe and replaced all my exhaust seals, Exhaust manifold gaskets, Exhaust manifold donuts, and even a exhaust manifold itself. There are no leaks in my exhaust but i still get Carbon Monoxide entering the cabin. Is there any type of solution to this. Please reply

the only way exhaust fumes are going to enter the cabin is from the rear, there are rear airvents.
are you using a carbon monoxide alarm or just smelling something....
