general problems of the 2017 Chevrolet Tahoe

Exhaust fumes and carbon monoxide are entering my cabin. I have replaced exhaust manifold gaskets (both sides), exhaust manifolds, exhaust manifold donut seals to the y-pipe and I still get carbon monoxide entering cabin giving my headaches. Please help.

My car has a problem this will be the 3rd visit to the chevy dealership and the 6th time in a garage. At this time, the original alternator that came with the Tahoe, was running high through December and replaced with a new alternator from parts geek. It was ok for a couple weeks and is running high again. You cannot test it from a cold start to get this reading. It must be ran for at least 20 min. After a certain amount of time the battery gauge will move to the highest point, the warning lights of abs, traction control, stabilitrak, trailer brake light, battery light (first time on 1/27/2026 for battery light), loss of drivers assist on 1/26/2026, tire pressure light, car dies coming to a stop sign. I can’t turn it back on for at least a min. I’m stuck inside with zero power, can’t unlock the doors to get out to direct traffic, open windows or put on 4 ways so I don’t get smacked in the middle of the road. After that minute I heard a click (no key in ignition, not trying to start) and then the dash lights started coming back on again and I started it. The battery did not restart the time on the radio screen so I’m assuming I didn’t die fully. The radio screen always goes black first, then the heat goes in and out, the warning lights come on and it dies. Takes a minute or so to be able to start it again and the lights aren’t on anymore but will continue to do the same shit after awhile of driving and now daily. I’m afraid to drive it anywhere since almost getting stuck inside and plowed at an interaction. I have reached out to chevy about this problem and was referred to take it back to the dealership again, and to reach back out as soon as it’s there to open a case on the issue. Ive had it, this has been ongoing for a year, and I have to keep paying for things that doesn’t fix the issue and it’s getting worse.

The contact owns a 2017 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, there was a misfire coming from the engine. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the camshaft. The contact was also informed that there was a misfire in cylinders #4 and #8. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA campaign number: 25v274000 (engine and engine cooling), but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 120,000.

I purchased this Tahoe in 2021i believe. I have replaced the transmission in 2024 for this z71 Tahoe and now the lifters are gone as well. In the process of going in the shop. I’m very upset. Tahoe’s cost too much for transmission, lifters to be going out and needing a new one installed. This is a major problem with Tahoe’s and I need some answers as to what can be done to help with this major issue. Who do I need to call or speak with to get this issue resolved. It’s a problem and no one wants to be accountable for making trash and selling it at high price for the consumer to pay for Chevrolet mistakes. Something must be done!!!.

Purchased 2017 Chevrolet Tahoe on 1/15/2025 with 50,647 miles on it. At exactly the 40 day mark, we noticed a problem when the vehicle began downshifting. When slowing down to stop at a red light, we could feel the transmission begin jerking as it shifted down and the check engine light came on. It has been taken back to the dealership (where we bought it), 5 times as of yesterday and they cannot fix the problem. The engine idles rough, downshifting is extremely hard, check engine comes on and off sporadically. The transmission temperature goes up and the dashboard lighting dims intermittently. This vehicle appeared to be in extremely good physical condition with very few miles, that's why it was purchased.

At 92,000 miles the lifters went out in vehicle. Repairs were done and replaced the gaskets, lifters and head bolts. After driving the vehicle another 12,000 miles lifters went out again. Gm is aware of the issue and does not to take responsibility or make a recall on the issue. It’s a very known issue with the 5. 3l engine in cylinder 1 to have a lifter failure.

The transmission dropped 2 thousand miles over my warranty at 102k miles. I was taking my son to see his surgeon and the car started jerking and making noises in the middle of a busy intersection. We almost got hit several times trying to get it to the side of the road for safety. I had to pay almost $1800 to get it towed home (we were in peoria about 150 miles from home to see his doctor). There were no indications the transmission was going out and never should have at that mileage. I always do regular maintenance and keep all my receipts. I then paid 6k out of pocket to have it replaced with a better transmission since I learned gm put a bad transmission in the Tahoe I have (I was told I missed the time limit to have it fixed on their dime). Then 6 weeks later a fuel injector and the lifters failed due to the active fuel management. No one was hurt thankfully because I was just leaving home to go to work when I noticed the tapping sound and had my mechanic come look at it. Him and 2 other mechanics confirmed it was the lifters. I had already borrowed money to replace the transmission and can’t afford the $12k quote to fix it. Now it has been sitting in my driveway for almost a year unable to be driven. It is however causing me severe depression. I’m borrowing my son’s car while paying almost $700 monthly on a Tahoe I can’t even drive. I was even more sad when I found out there’s thousands of people with the same issue. Gm should be ashamed of themselves!.

When pulling out of my driveway my gas pedal foot became stuck on the gas pedal. I could not remove my foot from the gas pedal. I immediately stepped on the brake pedal and then my Tahoe accelerated rapidly. I removed my foot from the brake pedal because any pressure on the brake just caused the car to accelerate faster. I then managed to wiggle my gas pedal foot from off of the gas pedal, it took a lot of effort. I was wearing normal men's shoes with no protrusions of any kind. I have recently seen in the news several similar occurrences including one that resulted in a fatality and others being injured as the car accelerated into an apple store. In two of these cases that I've seen in the news the drivers have reported that their foot became stuck on the gas pedal and when they applied the brakes the car accelerated out of control. This is exactly what happened to me except I managed to get the car under control before I hit anything. My inspection of the Tahoe's pedals revealed that the two pedals are very close to each other and when applying the brakes the brake pedal comes down on the foot that is somehow stuck on the gas pedal. I believe the stuck accelerator foot was somehow trapped under the brake pedal. The pedals are too close together.

The contact owns a 2017 Chevrolet Tahoe. The contact stated while driving approximately 40 mph, the vehicle stalled. There was no warning light illuminated. The vehicle was able to restart. The vehicle was taken to the dealer, where it was diagnosed with engine lifters failure. The dealer replaced the engine with a used engine. The contact stated that the transmission was replaced 3 months later. Additionally, the contact stated that the vehicle stalled while driving 40-45 mph on another occasion. The vehicle was restarted and was taken to a second dealer, modern Cadillac of burlington (2616 alamance rd, burlington, nc 27215), where it was diagnosed with engine lifters and camshaft failure. The vehicle was not repaired due to the cost. The vehicle was parked at the residence. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 107,000.

I have a 2017 chevy Tahoe with 77,000 miles on it. I will have it 4 years labor day weekend. I get all the regular service and oil changes on it in a timely fashion. Last week I was driving my daughter to a friends house and there was a tapping sound. The car did not sound right. Suddenly the engine light illuminated and was blinking. The car smelled of gas. Thankfully I wasn't too far from home. I had to drive on a highway to get back to my house. I could only go about 30 mph. It was very dangerous. I had my hazards on but people were still beeping at me since I was causing a safety hazard for myself and others. I managed to get home safely and called the dealership. I dropped my car off the next morning since it is not drive-able. The service rep said it was going in as an emergency. After 5 days they finally looked at it. They did not give me a loaner. If I wanted a loaner I was required to pay $46/day. The rep said the repairs to my 3 year old car wont be covered and it will cost over $5,000 to fix the engine. It is a known engine issue to chevy corporate bulletin 15-06-01-002h engine misfire/tick noise, malfunction indicator lamp illuminated. It is common in 20-15-2019 Tahoe and suburban. I had to borrow a 12 year old car to drive around my 4 children because my 3 year old car has a bad engine. Ethically how can chevy require their customers to cover a cost of an engine that they know is faulty. There was nothing that I did to cause this issue. I will never purchase another chevy. Shame on paramus Chevrolet.

January 25, 2020, I purchased a 2017 Chevrolet Tahoe and the a/c condenser has a leak and must be replaced. The dealer charged me $148. 50 for the diagnosis and quoted the repair cost $1095. 12.

Why is NHTSA allowing sale of millions of dangerous unfixable airbag recalled suvs to be driven when the consequence is death by an allowed life threatening problem in a majority of cars on the road. Why is there no protection of innocent people here. This is unacceptable regardless of what is or isn't allowed. Every car with this recall is a deadly risk and NHTSA is not getting dealers to stop selling such vehicles nor are they investigating the many dealerships that are hiding the issues by saying multiple different lies in the description and hiding it in the carfax but keeping it in the VIN check. Nhtsa has a duty to protect us all especuu iti ally now I'm thus rare instance where every vehicle on the road is a death sentence by the very safety device meant to protect , the airbags, which is one thing if does not inflate, but is worse that it shoots metal shrapnel when airbag explodes instead of inflated and has already injured and killed 19 people and no way to prevent explosion since no remedy but at the very least, is it not better to deactivate the possibility of it exploding instead of allowing it to be sold and harm people? this is very serious and should be investigated by all branches of government t related to vehicles dmv, dot, health and safety and fbi, because it is shocking that it has gotten thus far along without any protection except it's announcement thus far putting millions at risk. I think someone is getting paid off under the rug for it to be such a hidden dilemma. Please send this article of concern out to all investigative entities to get our kids and families protected. I had to use a VIN from a vehicle if interest from a sample car dealership for this complaint otherwise it would be neglected further. Email: (xxxxx) . Regarding my concerns for this safety issue. My name is (xxxx). Which SUV can be bought? redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
