general problems of the 2015 Chevrolet Suburban

While driving at highway speeds my vehicle lost steering the radio and the hvac turned off. I had abs and brake lights on the dash as well as a service stabilitrac message. The vehicle completely shutoff and I almost had an auto accident. I have not taken it anywhere as I’m to afraid to drive it for fear of having an accident.

Replaced lifters 1,3,5,7 and added automatic fuel mgmt system bypass chip after the vehicle went into limp mode on the highway. Ran for less than 2000 miles and those same lifters failed a second time and had to be replaced again. The last incident occurred after about 200 miles and had engine failure, limp mode with multiple sensor failures in the middle of the road in the dark. Limited ability to move it safely off the road.

I have a 2015 chevy Suburban with a 5. 3l v8 motor. At 123,067 miles I lost the lifters in the number 7 cylinder due to the active fuel management (afm) system. This is an ongoing issue with chevy motors from2014 to 2021. There is currently a class action law suite. I am hoping the NHTSA will issue a recall. This repaid cost me $4,000. 00 to repair.

The contact owns a 2015 Chevrolet Suburban. The contact stated that while driving approximately 40 mph, the vehicle lost motive power, with an abnormal clicking sound coming from the engine compartment. The vehicle was taken to an independent mechanic where it was diagnosed that the hydraulic lifters needed to be replaced. The vehicle was not repaired. The vehicle was then towed to the residence. The vehicle was towed to a dealer where it was diagnosed that the hydraulic lifters needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 91,800.

The # 7 cylinder valve lifter in the 2015 Suburban engine fails when accelerating in certain situations. This has happened to this vehicle twice at and expense of rebuilding the engine. The in both cases the vehicle was accelerating into fast moving traffic. When the lifter fails the engine loses power and no longer accelerates which requires swerving out of traffic, back to the shoulder to not get rear-ended by on-coming traffic. The problem was confirmed and the service provided indicated that this was a significant issue with this particular engine. Basically, it happens to many of these vehicles. The engine has been rebuilt twice while I have owned it. When the lifter fails the check engine light comes on. These failures occurred on September 24, 2021 and again on September 9, 2023.

Transmission has failed. . .

El problema DE esa camioneta esque lla se le a cambiado 3 veces los catalizadores uno alos 30 mil millas y oto alos 80 mil millas y el otro alos 165 mil millas y haora tiene 168 mil millas esta com el código p0430.

Clanking, stalling , wouldn’t go into gear. Had to have the truck flatbed to aamco. Was told transmission. Call chevy during issue’s and told vehicle was not part of recall. Transmission had to be replaced.

Vehicle a/c condenser has a leak parts are on backorder because of the number of failures.

The contact owns a 2015 Chevrolet Suburban. The contact stated while driving at various speeds, the steering wheel became stiff, and the vehicle lost automotive power. The check engine, seat belt, stabili-trak, and abs warning lights were illuminated. The contact stated that the vehicle was occasionally towed and taken to the same local dealer on several occasions, where it was diagnosed; however, the failure was not yet determined. The transmission, fuel pump, battery, alternator, and unknown wiring were replaced at the consumer's expense; however, the failure persisted. In addition, the contact related the failure to NHTSA campaign number: 18v586000 (steering); however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 117,000.

The transmission failed shortly after purchasing used in Jan of 2021. We were driving on our family vacation from ohio to south carolina and the transmission failed in north carolina.

Driving today in snow, increased electrical demand on vehicle while accelerating. Smelled burning wires and all dash lights flickered then died. Engine turned off and had to be restarted with the push button. Happened within 30 minutes later while accelerating onto a main road with traffic, lost control of vehicle and had to force the steering wheel to turn the vehicle off the road to avoid being hit by oncoming traffic.

Oil pressure, temp, tac, speedometer, gauges fluctuating , while many failures flash on the driver info center screen, audio warnings also. Engine revs and power steering fails. This has happened in all driving conditions, stopped, city ,country , highway roads. This has happened about four times, and we have it at a dealer now for the third time. The first dealer could not duplicate the problem. Second dealer said the problem was a steering lock control module and replaced it, the third dealer is still working on it. The loss of power steering ,making the car very hard to steer is what has prompted me to make this report. This happened for the first time ,August 13, 2019 and the last time ,January 29, 2020.

Tl the contact owns a 2015 Chevrolet Suburban. The contact took the vehicle to smicklas Chevrolet (located at 8900 northwest expy, oklahoma city, ok 73162, (405) 943-5721) to be repaired per NHTSA campaign number: 18v586000 (steering). The dealer informed the contact that the steering gears needed to be replaced. In addition, the contact received a notice for an unknown recall regarding the brakes. The brakes were repaired, but the contact was informed that the engine vacuum pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified. The failure mileage was 84,800.

At low speed (backing into a parking spot on the street) the brake pedal got very hard and the vehicle would barely stop. I then did not go into that space to avoid hitting the car behind me. I pulled into a parking lot across the street. When backing in, I could not stop (moving with car at idle engine speed). The hitch hit the concrete wall-happily no damage done. With research, I find this is a common problem that gm has not addressed. I usually occurs at slow speeds or stop and go slow speed traffic. This is unpredictable and very unsafe. The vehicle is a 2015 with only 35,000 miles. The vacuum pump (the failure) is bolted to the engine and engine-driven and lubricated by engine oil which puts my engine at risk. Yet none of this is covered by the power train warranty. This is not a slow, but a sudden failure item. Very unsafe if it happens in school parking lot picking up my children, church, close spaces (neighborhoods, parking areas).

A knowen issue with the Suburban- dead lifters, often the dealerships don't want to repair the engine, they tell customers to get a new or rebuild engine. The issue is a hidden secret which I hope with this complaint gm will come clean and recall million of cars on the road with this defect.

Roof mounted "shark fin " antenna leaks and resulted in short circuit of the electrical controls disabling the Suburban. Second time in 2. 5yrs the antenna had to be replaced.

Ac condenser broke, told by gm special coverage take to dealership, dealership said no coverage. Had 3rd party fix at reasonable cost, called gm and told yes we will pay for parts take receipt to dealership, dealership said no! will not pay, will not file, will not help! gm now says will not pay after multiple phones stating they would!.

While driving all of the power cuts off including power steering. Alternator, oil, fuel, struts, battery x 2 have been changed out in attempt to correct issue. Issue is still present. Local chevy dealership unable to rectify problem. There have been numerous incidents with potential accidents. There seems to be a power draw on the system, unable to find any kinked or frayed wires. While driving all lighting including gauges dims usually prior to complete vehicle electrical failure. I have a video of electrical dimming, but unable to load on here. Vehicle is labeled as 2015 but manufacture date is 2014, ive noticed there is a recall on 2014 models for electrical chassis failure however my VIN is not encompassed in this recall.

Transmission stopping on highway.

There was a not any big event that caused it. Air conditioning was blowing cold air on Monday June 26, 2017; on Tuesday June 27, 2017 it was warm air even after driving around for 5 minutes. Immediately took it to the dealer we purchased it from: priority Chevrolet. The condenser had stopped working. Couldn't hold freon because there was a hole in it. . . . ?!?!?! not sure of the cause. My car is barely 2 years old! I have four young children in the middle of summer. Initially we were told 1-2 month wait!? apparently this isn't the first condenser they have had to replace. Tells me something isn't isn't right with Chevrolet.

I was on slope hill. My brakes are not responding. I put in new brakes 2 months ago and brakes not responding? my car almost went down the hill. I called roadside assistance and had them towed my car to dealership. They found the issue vacuum pump broke. Also my transmission having issue since 2 months. They still haven't found issues. I can't control my speed and engine gives a kick when entering highway. They won't repair this issue because their "mechanics" cannot find the issue. This is this worst vehicle to drive andunsafe for drivers and passengers.

Dear sir or madam my vehicle a/c problem no cool air , only warm air ，and I paid to dealerships 166. 52 just for checking what problem ！they find out condenser leaking, the dealer price is 1159. 63 to repair it , I am limo driver this vehicle for business use! my campany have hundreds driver have same vehicle , and they have same problems, all vehicles from gm factory includes GMC Chevrolet Cadillac same problems , I am able to collect all the signatures to prove it . This is problem of manufacturer production processing! but I paid $664. 13 repair it ! who pay my lost ? please help me.

A/c no cold air. I went to dealership and they tested and said there's huge hole. Apparently they only said small leak. They replaced with new condenser. I was forced to pay nearly 1,400. Also resurface front disc brake. This is brand new vehicle and over 20 vehicles I know have same issues. There should be recall on this vehicle. I went to dealer and they said deal with gm. I went to gm they won't resolve my issues.

The contact owns a 2015 Chevrolet Suburban. The contact stated that a strange odor was present in the vehicle. Several occupants endured migraines, vertigo, nausea, and vomiting while in the vehicle. Medical attention was not required. The vehicle was taken to a dealer, but the cause of the failure could not be determined. Several components were repaired, but the failure was persistent. The failure mileage was approximately 18,351.

We have multiple problems with our new Suburban. After traveling slowly or coasting in traffic, when I try to accelerate the vehicle won't go and when it finally decides to go it shudders and vibrates badly, it also does this from a complete stop, been to the dealer 2 times so far this and the last time they told me "it is a normal characteristic of vehicle". It is a very bad one and it will cause a wreck! the radio display flickers all the time even when back up camara is on, gm has no fix for this yet either! the vehicle sticker says it has heated/ac seats, it doesn't have a/c seats, they are airrated from the air in vehicle, that was a total misrepresentation of the product on the sales sticker. Gm rep had us test drive another Suburban and we drove 3 different ones and not one of the others did the things our does. When we informed gm of this they said sorry we don't qualify for a buyback/replacement. Gm doesn't care to help and its their very expensive product. I hope no one dies or is injured from the hesitations that gm know these vehicles have that is 0. 7 seconds before the vehicle will engage or reengage when excelerating from a slow roll or a complete stop.

When driving the 2015 Suburban we experience an awful ear pressure and vibration. The car is not driveable and is causing headaches and vertigo. The problem is known by service techs and gm. They believe there is a problem when the car transitions from v8 to v4. There are multiple forums online regarding the issue. Gm has not issued a fix as of yet. From what I have read, the problem is found in 2015 Suburbans, escalades, and yukon xls. We purchased the vehicle with 1750 miles on it. After putting 500 miles on it, we cannot wait to get rid of it, and have attempted to initiate a buyback procedure with gm.
