Help-2024 Tahoe Stalled

[NT1978]

Hi all,

I purchased my first ever GM product and got a 2024 Chevy Tahoe LT (5.3L) in January. It has 12,000 miles on it and has been a good ride until today when I was driving down the road and the car began to stutter and then the engine just died. The radio and infotainment system still worked, but when I tried to start the vehicle it would grind but not start. I had the vehicle towed to the nearby dealer tonight and will have to call them in the morning.

Has anyone ever heard of this happening with a brand new Tahoe?

What is the cause of this issue and what is the fix?

 

[OR VietVet]

So many new components and accessories and tech added as each year goes on and so many things to go wrong. Getting that special "who who ha ha tickler" was the last draw.

Almost every day, a member has a tale of whoa about their new GM SUV dying. I feel for ya, I do.

Man, I really love my 2005 Tahoe Z71 more and more every day.

Looking forward to the "gobbledeegoop" explanation you are given.

 

[NT1978]

I am really just looking for others who may have had this issue and what the diagnosis was and potential fix if there was a fix. Is it an engine issue? A fuel pump issue? Something else?

the grinding noise is not a good sign, but there have been fuel pump control issue's and internal engine failures, I am sure the dealer will let you know which is the case

When you say "grinding", do you mean it cranked like it was trying to start while making normal cranking sounds, or was it literally a grindy metal-on-metal sound?

If your Tahoe was cranking relatively normal but just not starting, I would put my money on it being the fuel pump control module (FPCM). My 2024 did that at only 320 miles and left me on the side of the road. Bright side is that it was a relatively quick fix and I had my Tahoe back a day later. They just had to switch out the module.

But if it is actually grinding and making noises other than typical cranking sounds, then it could be something else more serious. Did it crank for a while when trying to start?

Well I was driving at 50 mph when it started making a strange noise almost like the tire had popped. The car eventually came to a stop and when I tried to restart the car it was making a sound like a car trying to turn over to start but it would not. Maybe that is called a cranking sound. It did not sound like metal to metal.

Is it common for a fuel pump to go out so soon? How many miles do you have on your vehicle now?

Talk to your dealer about the specific diagnosis. There are different causes. Note that the comments were about the fuel pump control module, not the pump.

there have been a number of reports of the fuel pump control module failing, no set mileage it's random

I had the same issue and it was the fuel pump module in the rear.... Second time it quit it was the dreaded catastrophe engine failure Towed to dealer and waiting for engine to be changed... 26000 miles

Thanks all for the feedback. The dealer is diagnosing it now and I just want to have an idea of what the problem might be.

So you had the car stall 2 different times with one being the fuel pump module and the second time it was an engine failure? What engine did you have...5.3 or 6.2?

 

[NT1978]

I got a call from the dealer, and while they are not done with the diagnosis, they said they found metal in the oil and believe it's an engine issue. I have only ever had Hondas and Toyotas and am frankly in shock that a brand new engine would already need to be replaced. Has anyone had their 5.3 engine replace within the first year? If so, did the replacement engine work fine for several years?

 

[KMeloney]

This will be a bit unusual if your 5.3 seized the way some 6.2s have.

...But most other failures I've read about here have been accompanied by a message on the screen about the truck being unable to shift, and folks have had to coast in neutral to the side of the road. Did you have this occur, too?

Unfortunately, FPCM failure seems to be relatively common. As mentioned, mine went out at 320 miles, I hadn't even owned the vehicle for a week at the time, so it was new-new. Must have been a defective part from the supplier to go out that early. That was in September, I got it back a day or so later and now have 2,500 miles with no further issues as of yet.

I saw your other reply about the dealership finding metal in your oil, so it seems you might have a more serious issue. Metal in the oil basically always results in needing a new engine. Please keep us updated, it's good to share the experiences we have with these vehicles. I feel for you though, having a new vehicle engine brick itself is an awful experience, it's highly inconvenient, and erodes trust in the vehicle even after repair. Being it's so new, warranty should handle the repair and you'll get it back in working order, but it still takes a toll on time, convenience, and trust.

Regarding your question about 5.3L failures under a year, besides a period of time around 2021 when GM received a bad supply of lifters, having a 5.3L fail within the first year is unusual. I'm on my third Tahoe, and my prior two both had the 5.3L. My 2008 went 11 years and 160K trouble-free miles, my 2019 went 5 years and was at 50K trouble-free miles when I traded it in, it was running perfect at trade-in, I just wanted a new gen with the 6.2L. My experience with those two 5.3L engines was excellent, they never let me down and a reason I'm a fan of these vehicles. I'm hoping my current 6.2L will serve me reliably, besides that little hiccup at 320 miles with the FPCM.

Thanks for sharing all of this. I stopped by the dealer and the technician showed me what happened. Part of the piston broke apart and he said he has never had to replace an 5.3 engine with the current gen Tahoe. I guess I am just the unlucky one. Also, the engines are on back order so I have no idea how long it will take to fix. They gave me a small SUV loaner but I am demanding a full size comparable replacement since it's still under warranty. I hope the replacement that they send has been fully tested and will last longer.

I have the 6.2. GM put out a bulletin on it but no recall. Sounded like marbles in the engine when it failed also metal shavings on dipstick

Have you heard back from the dealer after they diagnosed the issue?
