The 2018 GMC Yukon was meant to carry a large number of people in style. Even the automaker claims that the newest lineup is a “luxury” full-size SUV, but there is a lot about this SUV that isn’t so opulent. Consumers complain about the electronic stability control, engine and steering.

Problems with the Electronic Stability Control
ESC was designed to keep drivers safe on the road. It’s used in conjunction with driver-assist technology to improve the drive as well. Except, these systems on the 2018 GMC Yukon are giving customers some trouble.
Look at this NHTSA complaint. “The contact owns a 2018 GMC Yukon. The contact received notification of NHTSA Campaign Number 19V761000 (Electronic Stability Control, Service Brakes, Hydraulic). The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the issue and stated that the part was not available. The manufacturer provided case number… The contact had not experienced a failure. VIN tool confirms parts not available.”
The recall being referenced states that a software error in the driveline-protection system might lead to unintended braking on one side of the vehicle, thereby causing the Yukon to pull dangerously to one side. This recall affects over 650,000 vehicles and it seems that dealers aren’t repairing the SUVs as they should. In the meantime, numerous owners are driving around with defective equipment that could lead to an accident.
Furthermore, another dangerous recall was issued. NHTSA Campaign Number 19V645000 affects almost 3.5 million vehicles. This recall states that the vacuum pump causes levels to drop, leading to a reduction in brake assist performance. This requires that drivers apply more braking power, which might prevent them from stopping in time. Between the GMC Yukon pulling to one side or not stopping at all, it’s hard to see this vehicle as a luxury model, especially with the sub-par treatment being offered by dealers.
Problems with the Suspension
The suspension is made up of many moving parts that are meant to cushion the ride. When these components begin to fail, the drive is rougher and often noisy as well.
That’s exactly what is shown through this NHTSA comment. “My front end makes noises when I turn wheel or stop. I took it to the [dealer] and they couldn’t find anything wrong. But it’s still making the noise.”
It turns out that GM is aware of suspension issues, despite what this service department said. Service bulletin #PIT5049E talks about squeaking, rattling, bumping, thumping and clunking sounds that might be due to trouble with the side shock or strut. Anyone driving this model is likely to think that it’s a budget-friendly, thrifty SUV versus the luxury model it is praised as. Owners often wish they had saved the money and gone with a cheaper brand that didn’t make the annoying sound effects.
Problems with the Engine
Arguably, the most important component of any vehicle is the engine. Without a potent motor, the drive is cumbersome and often unenjoyable. That’s precisely the case with the 2018 GMC Yukon.
Take a look at this Edmunds review as an example of what customers think. “I was so looking forward to purchasing my first real large SUV. Reviews on GM Tahoes and Yukons are positive but my experience was terrifying. My wife and kids hate to ride in it as it shake at idle in Drive position. GM and dealers are saying no codes, we stopped troubleshooting here. $65K truck that shakes like 1988 Yugo… What a treat, but what is worst is the lack of support. If you think manufacturer’s warranty is there to support you bumper to bumper, think again, if truck is dead or there error codes they will fix it, if no codes you are so out of luck. I took it to the independent, they found the issue with injectors but since there are no codes, GM would not authorize a repair. GM support will send you on such long wild goose chase, you would never come back. I am pro-business but in this case I wish there was more consumer protection in place.”
The automaker isn’t attempting to hide any engine-related issues. GMC even issued Service Bulletin #19NA212, which states that technicians need to check if the camshaft alignment pin has been sheared away. This problem shouldn’t occur with high-end vehicles that use premium materials and attention to detail, yet that’s where owners find themselves. If owners want to deal with these problems, they can find a much cheaper and probably reliable vehicle than this expensive Yukon model. It’s time to redefine what luxury means.

| Description | May 31st 2022-while driving on the highway, I lost control of my power steering. Luckily my husband was with me to drive it back home. June 1st 2022-took it to a service center and was told it needed a part to fix the problem. We ordered the part, which would not be delivered until may 6th 2022. June 4th 2022- went to drive, made it a couple blocks down the road when the abs, electronic stability control, & the engine light came on. So I turned around to take it back home, only now my power steering was completely out, my car would not shift out of first gear. After arriving home, I attempted to put it in park but was unable to. My motor shut off but would not allow me to place it in park or turn the electric power off. The only option I had was to disconnect the battery. I let it sit for a few hours, reconnected the battery, now my car will not start at all. I am now unable to take my car to the dealership due to power failure note: june 2nd & 3rd, my vehicle was not driven I did contact my local dealer to check if there were any open recalls, was told no |

| Description | The torque converter is too small for the vehicles transmission which then caused it to break and put metal into the transmission fluid. Which cause the transmission to break. My safety was at risk was because while on highway it shot high on rpms and then made funny noise and wouldn't go. The problem was confirmed at aamco transmission where I have to get the transmission rebuilt. There was never a check engine light or check fluid or any codes thrown before the problem. |

My vehicle sustained major damage (,000+) to repair according to the body shop. My wife, daughter and myself sustained injuries. My wife and I have significant injuries. I truly believe, based on vehicle damages, and injuries that our airbags should've deployed. I believe it has a fault sensor that should be inspected. |

| Description | Headlights are terrible. Driving at night is treacherous because the headlights are not very bright unless I can use brights which seems like they could be low beam instead of high beam. With oncoming traffic it is hard to see the road and I get scared it may cause an accident, either hitting an oncoming car or going off the road myself. It's terrible. Others have commented on the headlights also asking me how can I see. There is no film on the covering over headlights. I can see the bulbs just fine but they look burnt. My husband thought so too. Just scared driving at night. Need better headlights! |

| Description | It's starting to warm up now that winter is behind us, so when we recently drove our 2018 yukon xl, we turned on the air conditioning. Unfortunately, only warm air came out of the vents. We made an appointment and took the yukon to the gmc dealer. We paid over 0 for their diagnostic fee (complete rip off), and they were immediately able to see that there was a leak in the ac condenser. The dealer service representative said that this has been happening quite frequently on 2014 and newer models and that they are all leaking in the same place, a weld on the driver's side of the condenser. Our yukon has ,000 miles…this is way to young for a condenser replacement. Dealer is quoting us over 00 for the repair. Gmc continues to build these cars without known defects and passes on the costs to the customer! By the way, there is special coverage adjustment 17336 that extends warranty coverage for this specific problem on gmcs, but only for 2015-2017 models. |

| Description | 2014-2018 chevy and gmc's have a problem with cycling of the thermostat that causes stress fractures on the radiator leading to coolant leaks. Attached are gm bulletins on the 2014 and 2015 models. As one can see they have provided special coverage on the 2014 models to 5 years or 100000 miles for this problem.(bulletin 15829) this is not true of the 2015 through 2018 like mine. Although they use similar verbiage in the bulletin p11513a and p11513f. It should be noted that bulletin p11513a and f also applies to 2015 cadillac escalade models, 2015 chevrolet suburban, tahoe, 2015 gmc sierra denali, yukon models, yukon denali models equipped with 4. 3l, 5. 3l or 6. 2l engine (rpos lv1, lv3, l83 or l86). ***basically this is a safety hazard because when traveling highway speeds it puts car into reduced power mode and you can only drive very slow on highway or be stranded on side which is just as dangerous *** |

| Description | On 3/20/21 I went out with the family out got to our destination well but when I started my vehicle to go back home I got a message on the display "service power steering drive with care" when I went to turn the steering wheel to drive I couldn't because it was too hard, after fighting it, I was able to drive my car back home with my family in it. Today 3/22/21 I called gmc to do a complaint and ask if there is a recall for this issue on this type of vehicle since I don't have any warranty anymore on the vehicle due to passing the 36 months by 1 month but not by mileage since I have 28500 miles on it. I was told by the gmc representative that at this time gmc does not have any recalls for this vin number. After doing much research I found that this is a very recurring problem with gmc, chevrolet and buick vehicles. On the past they have done recalls for this type of problem but the lovely automakers and lobbyist are finding the loop holes so they are held accountable for known mistakes until some family tragically dies in an accident due to automaker not being held accountable for known issues. Please do something about this issue, tooooo many customers having this issue and no accountability on automakers behalf. |

After we exchanged information I drove off and I kept stopping to see if the brakes were working, but they worked every time after that. I was telling my sister what happened and she mentioned a friend of hers had a gmc that was recalled due to faulty brakes. She suggested I check on your site. I check but it said 0 recalls. I wanted to be sure I let someone know because the car did not stop when I really needed it to stop. |

| Description | Tl* the contact owns a 2018 gmc yukon denali xl. The contact noticed that the vehicle shook excessively and there was a strong vibration while driving at highway speeds. The vehicle was taken to the dealer (bommarito buick gmc west county, 15736 manchester rd, ellisville, mo 63011, (636) 391-7200) more than twice, but they were unable to determine a remedy to repair the vehicle. The dealer test drove the vehicle and the contact asked for an alignment. On the second visit, an alignment was performed and the tires were rotated and balanced; however, the failure continued. On the third visit, the dealer indicated that the tires were out of alignment and one tire was replaced; however, the shaking continued. The vehicle was not repaired. The manufacturer provided no specific remedy and provided the vehicle as a trade-in from a 2017 gmc yukon denali xl, which exhibited the same failure. The vehicle was not repaired. The approximate failure mileage was 5,000. |

| Description | I was driving my 2018 yukon denali on a 3 lane interstate with gm's new adaptive cruise control turned on.. Another driver cut in front of me from the right. Adaptive cruise slammed on the brakes almost causing a rear-end accident by overcompensating. This happened more than once on a 2000 mile trip in different traffic conditions. In contacting my dealer, they called gm and were told it could not be fixed because of extensive supposed changes to the vehicle. However, other gm vehicles have a shutoff that would eliminate adaptive cruise and let you normally operate cruise control. I was then told by the dealer that I would need to contact gm directly. The case number is 8-4468390871. In pursuing this with several gm representatives, they claim there is no fix without extensive changes in software, wiring, and programming. But also revealed they recognized it is a problem and have provided a shutoff on future gm yukon denali vehicles. Ironically, this fix is already on a buick envision, acadia, and possibly a chevy equinox. Gm's response is to spend my money on a new vehicle to fix their problem. My vehicle only has 2300 miles on it. I consider this adaptive cruise feature an accident waiting to happen with drivers not expecting the radical braking as well as other drivers not expecting it, thus possibly causing chain reaction crashes. |

We own a 2018 Yukon XL Denali with 72k miles. We just replaced the front struts, at the recommendation of the dealership we bought it from. The ride has not gotten any better, in fact, it seems worse. Riding in this vehicle is becoming a terrible experience. The ride quality is so bad that we thinking if get rid of it, however we would like to keep it. It seems that the struts are known issue. They use air struts, not coils, which are designed to provide a better ride, but that is not our experience, at least at this mileage.
I would like to seek some redemption, as we feel we have a truck that will continue to disappoint.
Is there anything we can do?
What about the tail lights? I have a 2018 Yukon and like many other that I see on the highway, the left break light does not work. Why is there not a recall on it? I’m not paying $800 for a new one.
