A 2021 Chevy Tahoe driver is growing increasingly frustrated with her vehicle after multiple service shop visits.<\/p>\n
Lauran Harris (@lauranharris733<\/a>) says she\u2019s disappointed that the techs have been unable to fix whatever is wrong with her ride, which has only has 55,000 miles.<\/p>\n Harris begins a TikTok by recording her Chevrolet Tahoe\u2019s engine. The engine starts turning over, then stutters violently before finally starting.<\/p>\n In the caption, Harris says she\u2019s tried multiple fixes to no avail.<\/p>\n According to her, she\u2019s brought the vehicle in for service on at least five separate occasions over the course of six months.<\/p>\n These include two belt swaps, a new alternator and water pump, and a trio of batteries.<\/p>\n \u201cHey @General Motors and @Chevrolet\u2014come get this POS Tahoe that has been in the shop 5+ times in 6 months. It\u2019s a 2021 and has 55k miles- had 2 new belts, a new alternator, a new water pump, 3 new batteries,\u201d she writes.<\/p>\n She concludes, writing, \u201cPlease explain why it\u2019s been problem after problem. I\u2019m at my wits end.\u201d<\/p>\n Multiple people tried to diagnose the problem with Harris\u2019 Tahoe in the comments.<\/p>\n One person speculated that the issue has to do with the car\u2019s fuel pump control module (FPCM). According to them, this was a prevalent issue associated with this particular GM SUV model. \u201cMaster GM tech here. FPCM is the likely issue. Very common on these,\u201d they said.<\/p>\n Others said they\u2019ve had similar issues with 2021 Tahoes<\/a>.<\/p>\n A user on the Tahoe Yukon Forum<\/a> urged other Tahoe drivers who own cars manufactured from 2021 and on to keep a \u201cspare FPCM\u201d in their ride at all times.<\/p>\n \u201cEven if yours has been replaced under the recall or due to a prior failure. Or even if you have the latest part #13554821 it may save you from being stranded as well as a lot of out of pocket expense and delays,\u201d they wrote.<\/p>\n They added that this issue occurs in both gasoline and diesel powered Tahoes.<\/p>\n According to Kemso Racing<\/a><\/em>, the FPCM isn\u2019t all that easily accessible, either. The outlet writes that on the 2021 Chevrolet Tahoe \u201cthe FPCM is integrated into the fuel delivery system in one of two locations. Mounted directly on the top of the fuel sending unit inside the tank or integrated onto the fuel pump module\u2019s internal circuit board.\u201d<\/p>\n According to Cars.com<\/a>, the National Highway Traffic Safety Administration (NHTSA) issued a series of recalls associated with the vehicle. The FPCM \u201cmay cause the fuel pump to fail or operate intermittently, which can interrupt fuel flow to the engine, and cause an unexpected engine stall,\u201d the outlet reports.<\/p>\n There were other recalls associated with 2021 Tahoes, too.<\/p>\n \u2018All On-Time Payments:\u2019 Woman Rents Her Car On Turo. Then It Gets Repossessed<\/a> Seat belts that can reportedly become trapped, electrical systems that can cause potential airbag failures, and improperly calibrated brakes at the dealership level are all potential causes of concern. Further, powertrain issues tied to the \u201crear wheel driveshaft assemblies\u201d that \u201cwere not heat-treated properly,\u201d were also purportedly cited by NHTSA. It also mentioned that transmission control valves on 2021 diesel Tahoes could be faulty as well.<\/p>\n Tahoe fuel systems may be missing enough adhesive in order to prevent fuel leaks, and should be addressed as part of the recalls issued for the popular SUV brand.<\/p>\n Numerous folks who replied to Harris\u2019 video believe that her issues boil down to one of these two problems: the fuel pump or the crankshaft. One user on the application echoed others who said that FPCM problems often pop up with this model year Tahoe.<\/p>\n \u201cIt\u2019s not getting fuel either. Fuel pump control module. It\u2019s bad\u2026we see it all the time when they come to the shop being towed.\u201d The same person also remarked that the gas pedal could be \u201cstuck down because the floor mat\u2026[is] not installed correctly or moved.\u201d<\/p>\n Someone else wrote, \u201cP129f covered under e2 emissions go get your fuel pump control module.\u201d<\/p>\n Another person argued that from the way her vehicle was sounding, that Harris\u2019s issue is related to the Tahoe\u2019s crankshaft.<\/p>\n \u201cEveryone is saying fuel pump control module but it\u2019s starting like high pressure pump is out on it. They will start and run on the 63 psi the low pressure pump outs out but have a long crank like this,\u201d they wrote.<\/p>\n \u201cLong crank time is either [the] crank sensor, cam sensor, or fuel pump module. I\u2019ve seen dirt and mud get into the fpm plug and cause this too,\u201d another said.<\/p>\n The crankshaft is also listed on the recall list<\/a> with regards to \u201cengine and engine cooling.\u201d This particular entry states that \u201cthe connecting rod and\/or crankshaft engine components may have manufacturing defects that can lead to engine damage and engine failure.\u201d<\/p>\n Some thought the issue might have to do with third-party components.<\/p>\n \u201cLooks like it\u2019s been customized with aftermarket performance parts,\u201d one said.<\/p>\n Another wrote, \u201cNever buy a metal intake. They\u2019ll heat soak and make your engine performance worse.\u201d<\/p>\n Someone else agreed. \u201cSorry bud\u2026that K&N air filter voided any warranty. But I\u2019m pretty sure they will give you like $5k in GMC loyalty cash if you buy a new one,\u201d they replied.<\/p>\n Harris denies buying third-party components, noting that she didn\u2019t pay for repairs out of pocket. \u201cThey\u2019ve covered all of those things I listed,\u201d she said.<\/p>\n Motor1<\/em> has reached out to Harris via TikTok comment for further information. We’ll update this if she responds.<\/p>\n \u00a0 \u00a0<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" A 2021 Chevy Tahoe driver is growing increasingly frustrated with her vehicle after multiple service shop visits.
