2019 GMC Terrain Complaint Log

The brake vacuum pump failed. I am extremely fortunate this happened at a rest stop after being on interstate 80 for numerous miles. Had this happened at highway speeds it would have been catastrophic for myself and most likely others. I do not have the part. The problem was confirmed and the psrt was replaced by Mavis Discount Tire in Mountain Top, PA There were no warning lights, signs, or symptoms prior to the malfunction. It is my understanding that GM has recalled the part on other models, but did not include the Terrain in the recall. I believe it should be before someone is seriously injured.

I was riding on the freeway when my brakes failed. i was not able to press down on my brakes with zero warning. I had to swerve to miss cars and pull on the shoulder of the freeway and my car still would not slow down. I finally got from 65 to 35 and pressed on my emergency brakes. I stopped the vehicle then my engine light came on and I got my car towed to the car shop where my car would not stop and suffered internal damage to my engine from the brakes and vacuum pump

Turbo Charge Engine

My ESC randomly comes on. Service parking brake message comes on intermittently. Messages pop a up saying steering wheel assist limited, drive with care. Again, all of these are intermittent but when they happen my steering wheel locks up. Even mid turn. Being intermittent it doesn’t always happen and weather seems to affect when it happens, or that’s a coincidence.

The contact called on behalf of her husband who owns a 2019 GMC Terrain. The contact stated that while her husband was driving approximately 50 MPH, the brakes seized, and the contact veered off into a lot to park the vehicle. The vehicle was towed to an independent mechanic where the vehicle was diagnosed. The contact was informed that the brake vacuum pump and the timing chain needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 72,000.

The brakes failed with zero warning while driving. Car only has 60,000 miles. Extremely dangerous and it looks like it has been reported and known issue! It needs to be recalled.

Headlights flicker when auto stop releases and clicks back on to move the vehicle. This happens when it wants too but usually at the same time service parking brake will pop up, followed by steering is reduced, drive with care.. Lets see what else. Carplay no longer works. No sound. sd card error pops up. Car will not play music through a cord but will via bluetooth, but charges a phone. OnStar light flickering between green and red until I turned off power to the liftgate. (manually clicking over knob to disable) Headlights flickering can cause accidents. Sure hope there's no epileptics out. Yes, orielly. I have documentation, photos, videos, take your pick I'm here to help. Not evaluated at dealer or mechanic, who can afford labor rates? This has been happening for months and I will continue to report till something is done or lives are cared about.

My transmission keeps sticking when I shift into drive or reverse. Just a couple of days ago, it happened the worst it has ever done before. I shifted into reverse and my vehicle was completely stopped when I shifted. I began to let off of the brakes and gently push the accelerator to start moving back, my vehicle then punched itself into reverse. I felt after that incident, something had to have been damaged. I’m almost afraid to drive my vehicle after that. When my vehicle punched itself into reverse, I was literally jolted towards the steering wheel and thankfully my seatbelt caught me. Incidents with the the shifting into drive or reverse have happened before, but never nearly as intense. About a year ago, I brought my vehicle in to my local GMC Dealership for a concern with my transmission shifting weirdly and holding itself in gear at an unnecessarily high RPM speed. The technician stated to me, “with these 9-speeds, they tend to get confused at various speeds”. I asked him to elaborate and he could not. These issues have now gotten worse. With my suspension, every turn I take, I get a kreaking sound from my front driver side wheel well. It sounds as if my tire if going to break off. I’ve done visual inspections and nothing out of the ordinary is noticeable to the eye. My vehicle is a 2019 with less than 40,000 miles on it. I should not be having all of these issues. I’m genuinely concerned for my safety.

on two occasions the vacuum pump booster failed causing the vehicle to lose braking ability while traveling on a highway at highway speeds. The vehicles brake completely failed and were unable to be engaged. the part was initially replaced by the dealer at the owner's expense and then the same issue occurred only a few months later. the second occurrence cause additional damage to the camshaft and timing chain causing the vehicle to not even be able to start. The vehicle was inspected by the servicing dealer and found metal shavings in the oil as well as extensive damage to the engine.

My family and I were returning home from vacation in another state, and while we were driving on the interstate, an alarm popped up on the DTC stating ruduced engine power. I tried to start slowing down so I could take the next off ramp and could not push the brake pedal in. I had absolutely no brakes trying to slow down from interstate speed. I was able to pull into a gas station parking lot while avoiding other vehicles. I was very lucky not to get in an accident. I had to have it towed to the nearest service center and was charged nearly $4000 for repair. The car has not ran right since we recieved it back. I called them back to let them know and was told the only way I would not have to pay to have it looked at was to bring it back to them. That shop was four and a half hours away from my house. The car was less than twenty miles out of the warranty when it broke down (nine miles to be exact), then they lied on the the paperwork and put the milage after they test drove it.

My daughter was driving her 2019 GMC Terrain at 15 - 20mph when she suddenly lost her brakes. Fortunately she had just turned into a new housing development where the road ended into an empty field. This could have been catastrophic for her & other citizens on the road. The following morning she would have been heading to work on a highway with heavy traffic with a posted speed limit of 65mph. We towed the vehicle home & after some investigating I found a vacuum pump failure. This vacuum pump broke apart internally sending chunks & shards of metal into her valve train. This issue is mentioned several times in Terrain forums & someone needs to address this issue before it becomes a fatality.

The contact owned a 2019 GMC Terrain. The contact stated that while the wife was driving at approximately 60 MPH, the brake pedal was depressed and it felt stiff. The vehicle failed to decrease in speed and as a result, the driver merged to the shoulder of the road however another vehicle crashed into the front driver side of the vehicle. The driver was able to merge to the shoulder of the road where the road bumps were able to decrease the speed of the vehicle. The ABS warning light was illuminated. The driver, front passenger, and rear driver's side passenger all sustained headaches and received medical attention via an ambulance on the scene. No occupants in the second vehicle were reported injured. A police report was taken at the scene and the vehicle was towed away. The cause of the failure was not determined. The manufacturer and local dealer were not contacted. The failure mileage was 40,000.

I bought a car from Boone Chrysler Dodge Jeep Ram dealership in North Carolina on [XXX] and by [XXX] my engine was out before I purchase my car I made sure they serviced my vehicle at a GMC Dealership and there's a warranty on the service of my engine I did not buy the warranty on my car because they couldn't guarantee that the warranty transferred over to West Virginia shop's and that they would cover issues they stated they could deny service cuz it was out of state. So my car went to Moses Cadillac GMC in downtown Charleston on [XXX] they literally just randomly dropped it back off to me two Wednesdays ago. I've been working with GMC to try to purchase a new vehicle and get mine bought back, but it's been a whole process but I'm trying to work with Moses so I can purchase a new vehicle but they won't call me back and i feel like its because they know something is defective. The engine had a Regen done before i purchased it and now all of a sudden the cars engine is Done. Now when this happened the battery got so hot my car started smoking we originally thought it was the starter. Because when it stopped working we were at a Toll booth and pressed the break and the stop start kicked the engine off and it never came back on. Even now if you try to start it the battery gets hot and the starter smokes. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving on the interstate and got to a Toll the automatic stop start stopped the car and the car never came back on. The battery and starter started smoking and the engine has gone out. No explanation no nothing and the Mechanics at the Gmc Dealership stated it just happens with these engines they just go out! I purchased the vehicle on April 9th before I purchased it I had the dealership send it to a Gmc certified dealership to have it serviced. I've attached the paperwork from the dealership as well.

The contact owns a 2019 GMC Terrain. The contact stated while driving 30 MPH, the brake pedal was depressed, but the vehicle failed to stop immediately. The contact slammed on the brake pedal, and the vehicle came to a stop. The contact coasted the vehicle to the median. The vehicle was restarted and driven to the residence. Upon inspection, the contact noticed that the brake fluid was dark in color. The vehicle was taken to an independent mechanic, who diagnosed that the vacuum pump had failed and exploded in the camshaft. The vehicle was then towed to the dealer, where it was determined that the vacuum pump, camshaft, valve cover gasket, and water pump needed to be replaced, along with an oil change. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 120,000.

Break booster pressure sensor and engine underbooster causes the car to slam on breaks or not break at all.

Faulty vaccuum pump blew leading to engine failure. On the highway randomly, with my child in the vehicle. This almost caused a huge accident. I’ve kept up on all maintence and oil changes. This has been a huge effect on my life as I’m a single parent and randomly had to spend thousands on a new engine for zero fault of my own. I’ve read many many people having this issue. Something needs to be done and action needs to be taken!!!!!!!!

I had just gotten off the highway and had gone less than a mile on a 35 mph road when the brakes acted like the antilock brakes came on for a brief second then the brake pedal became very hard to push. This resulted in me having a difficult time stopping the vehicle. The service brake light also came on.

Vaccumm pump failed and broke metal shavings off into engine resulting in “engine failure”. I was driving on the highway with my 6 year old child in back seat, car completely shut down and shot a “reduced engine power” message while on a busy on ramp heading onto highway. This created an extremely dangerous situation for myself and my child as many cars almost smashed into the vehicle. I’ve seen many other complaints of this happening, the same exact parts and issue happened to the Chevy Equinox which resulted in a recall but they have yet to recall the Terrain, which is having the exact same issue. I am a single mother, with 20k still on my loan. This mistake made by gmc has now costed me over 5,000$ out of pocket for something that is not my fault and completely out of my control. Even after all of the money poured into this repair, I still feel unsafe in my own vehicle as there is no guarantee this issue will not happen again. I’ve kept up on all oil changes and maintenance of my vehicle. The issue was confirmed by a GMC mechanic which cost 500$ out of pocket for diagnosis as well. I also had to spend 1000$ on a rental out of pocket because of this. I have seen many others complaints of the same issue happening to their GMC terrain and am appalled no recall has been discussed after the reaccuring issue. I should not be having to pay out of pocket for an issue GMC has yet to fix or issue a recall on. I had to miss days of work, and it really was a huge inconvenience. I do not feel safe in my own vehicle even after the repair, cause I have no guarantee this won’t just happen all over again.

While driving on 95, I lost all engine and power breaks with no warning. A message came up on my dash stating that I had lost engine power. Fortunately an exit was up ahead so I was able to get there and coast down the ramp. I attempted to make a right turn to get out of the way but ran out of momentum. Dealership stated my vacuum break pump failed and went into the cam shaft. They had to replace those and the solenoid actuator and value. They also conducted an oil change. I received it back yesterday, started the car today and the check engine light was on. They found more debris and replaced another point and said if the light comes on again it's the timing chains in the engine. I went out leave and the check engine light was on. They are now keeping it to repair the timing chains. I am fighting with GM to cover the expenses since I see this is an issue in previous models/years of GMC and Chevy vehicles.

Brakes got hard all of a sudden locked up, almost hit another car, front collision warning keeps going off and automatically hitting brakes with no one in front of me. I’ve read it could vacuum brake pump failure. Please recall this as many people have kids and could hurt them.

First the car started jerking while drive over 50mph, next day driving down the street and the car shut off, stating loss of power. I replaced the battery, it was giving battery low codes, only to get a certified mechanic say the timing chain was out. Just purchased the car in March 2022.

It began with showing "Service Brake Assist" for about 2 weeks + then on Dec 18th 2023 around 10:30 as my fiancé was stopped at a stoplight and all of sudden when the light turned green she attempted to continue forward as traffic started to move only to stall stalled out before any movement could be achieve the battery was reading severely depleted and the vehicle would not function at all she was stuck in Drive and could not put the vehicle in neutral or even park to even try to restart the vehicle, she could not even turn the steering wheel, roll down the windows, open the door, or anything. the only thing she was able to accomplish was opening the hood so an officer that had arrived at this time could give her a jump, The officer also proceeded to leave the negative cable on the battery terminal and disconnected the Positive cable from the battery terminal which would have indicated a bad starter or depleted battery when the positive cable had been removed, which was not the case. she continued to where her appointment was and that is where i met her and took over vehicle to transport it home, driving with hazards on. I arrived at the house with no incident. then at 4:45pm on the evening of 12/18/2023 while at the stoplight I had a similar issue occurred as i was going from a stationary position to a forward slowly accelerated speed gaining momentum where the vehicle wanted to stall out while i was stopped at a stoplight attempting to proceed forward. and then at around 10:20 pm while stopped at a stop sign a similar issue occurred as i was going from a stationary position to a forward slowly accelerated speed gaining momentum attempting to proceed forward. On Dec 19th 2023 around 10:00 am I test started the car by remote and it started up and then i turned it off, now it is showing that the battery is completely depleted at 1:26 pm

Engine overheating, cooling system contaminated with engine oil. Originally brought to dealership [Crown Buick GMC - 2121 Clearview Pkwy, Metairie, LA 70001 - (504) 302-8979] November 27, 2023. However, they were unable to identify the problem. Since the engine continued to overheat, brought the vehicle to an independent mechanic [EFI Services, Inc. - 5720 Heebe St., Harahan, LA 70123 - (504) 734-8200] January 25, 2024. They shared Service Bulletin 22-NA-240 and said it should be covered under powertrain warranty. Brought it back to the dealership [Crown Buick GMC] January 19, 2024. They informed me Bulletin 22-NA-240 did not apply to the vehicle year (2019) was not included. They also informed me no work would be covered under warranty because it expired December 18, 2023. I continue to have to refill the coolant due to overheating, and oil is clearly present.

My 2019 gmc terrain, vaccum pump failed at about 45000 miles, was driving on the highway and brakes were hard to stop, almost crashed. About 52000 miles, vacuum pump failed again, also while driving on the highway. Brakes were hard to stop, again almost causing me to crash. 69000 miles again vacuum pump failed while driving on the highway, again almost causing me to crash. All times pump was replaced under warranty and now this has caused my engine to fail. i was denied factory warranty, pre certified and extended warranty. Now im stuck with a car with with three years left to pay on it

When turning right or left from a stop, the steering wheel jerks sharply in the opposite direction as soon as the car starts to accelerate. Diagnostic tests and inspection determined that the steering gear is loosing voltage causing the jerk in the steering wheel. The gear has the latest calibration and needs to be replaced. Cost estimate to replace is $2035.63

For the third time, the brake booster has failed on our GMC Terrain. We had the first replaced with an OEM part. That booster failed after 2 weeks. A second OEM brake booster was installed. That one lasted about a year until it failed as well. This time we were traveling down the interstate and interstate speeds. There were no indications of an issue until trying to slow down when attempting to exit the interstate. Luckily it was a long ramp and there was not much traffic as I had to push extremely hard to slow down the vehicle. Knowing immediately what had happened, we noticed a GMC dealership was just down the road and safely made it. We left the vehicle at the dealership and rented a car to continue our vacation. We are now being told that not only did the brake booster fail, but the components entered the engine and caused major damage. The suggested repair is a full engine replacement. This is unacceptable for an issue that GMC has know about and has had recalls for on other years of their vehicles. Not only could my family have been severely injured, or worse, we are not financially able to repair the vehicle.

jerking at times while driving.

There are 3 recalls and one open on this car I was sold by a dealership, none of them ever fixed. I drive to work in the highway the car never had any warning light on but the RPMS would occasionally go up for no reason. I told the dealership the second day that it had issues , they took it and say they fixed the back brakes but did nothing about the engine or transmission whatsoever ever. This was the beginning of may and it was in the shop two weeks. I called my lender to even get out of the loan and a saleswoman even tried assisting me into talking her manager out of the loan because of all the issues. Fast foreword to august I had just gotten a new job and was driving in the night after hearing that ticking or slight knocking noise and I went to my job and as i tried to park the brakes went completely stiff on me! I could not get the car to slow down I had to weave through other cars and people in till it finally coasted to a stop. So I put it in park and immediately after the check engine light came on. I tried to start it and it would start , putter and turn off over and over. I had to end up calling OnStar to have a diagnosis which she said something like solenoid and something being clogged. So it was towed to my residence and before i could get it towed to s shop they lender came and repossessed it because I had missed payments due to losing my job unexpectedly, completely unexpectedly. I told the lender of the problem and the unfortunate troubles I was having to pay for the car but I had just landed a job and could start payment but she didn’t care. She said she is going to tow it . I had my friends dad who is a licensed mechanic look at it before it was towed and he said the car was trash , basically a lemon that there was oil clogged and instead of passing through like it’s supposed to do it being pushed the opposite way and ending up in other reservoirs it shouldn’t be in. I obviously didn’t do that type of damage oil and trans problems I was scammed

2019 gmc terrain with 45000 miles, regular maintenance performed. Driving on highway 70mps brakes failed with no warning. No issues with brakes or lights coming on up to this point. Brake pedal became stiff very minimal brake working lights began flashing on dash stating "service brake assist". Barely made it off the highway without a catastrophic Collison. Took car in states brake vacuum pump completely failed. Apparently there are many models of gmc/chevy that were recalled and have known issues with the brake vacuum pump. Not sure why the terrain is not included. It needs to be, this was a very dangerous situation. I had children in the car and was very scary! 600$ to repair, and from reading other reviews the pumps are breaking often, sometimes ruining engines. Gmc stand behind your product and fix this!

When parked in home driveway brake lights came on with no one in car or driven during the day. Only way to turn off brake is to remote start & then cut off engine with Fob. Dealer diagnostic unable to find issue & condition didn't occur when at their location.

When trying to accelerate, the car will not accelerate. It will start to jerk back and forth and I had cut it off completely in the middle of the road at a stop light.

The contact owns a 2019 GMC Terrain. The contact stated while driving approximately 40 MPH, the accelerator was depressed to overtake a vehicle; however, the vehicle hesitated, and RPM revved to 4,000 RPM. The vehicle then shifted into gear with a jerk, causing the vehicle to shake abnormally. The contact stated there was no warning light illuminated. The contact stated that the failure also occurred while accelerating from a stop. The contact had taken the vehicle to an independent mechanic who diagnosed the vehicle but was unable to retrieve a fault code. The vehicle had not been repaired. The contact stated that the failure was intermittent but persistent. The manufacturer had been informed of the failure. The failure mileage was approximately 60,000.

The contact owns a 2019 GMC Terrain. The contact stated that while driving at approximately 75 MPH, the panoramic glass sunroof shattered, causing shards of glass to enter the cabin of the vehicle. The contact stated that the panoramic sunroof was in the closed position when the failure occurred. During the failure, the front passenger sustained lacerations to the back, leg, and shoulder. The eleven-month-old child seated in the rear passenger’s side seat sustained lacerations to both legs. The rear middle seat occupant sustained a laceration to the rear head area, while the rear driver’s side occupant sustained lacerations to both arms. No injuries required medical treatment. The cause of the failure was not yet determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was 58,000.

In July 2022 vacuum pump failed and created a hard brake situation going 55 mph downhill. Vehicle removed from roadway safely, transported and vacuum pump replaced. In May of 2023 vacuum pump again failed driving at around 25mph, vacuum pump failed catastrophically and blew up inside cam cover. Taken to garage via flatbed and reported car needed a new engine or alternatively we could try a new cam and vacuum pump with hopes pieces did not make it into engine. Now vehicle sits while I still owe money as I do not have 3-5000 to repair it. The fact that this is such a common issue and has happened frequently with other GM models is criminal. I feel as if GM should offer a buyback on affected models or reimburse customers for damages done. Vehicle is outside of warranty currently at 83k first vacuum pump failure occurred at around 70k.

The contact owns a 2019 GMC Terrain. The contact stated while driving 10-12 MPH and approaching a traffic light, the brake pedal was depressed, but failed to respond and went down to the floorboard. There was no warning light illuminated. The contact stated that she continuously pumped the brake pedal until the vehicle stopped. The contact veered to the side of the road. The "Low Brake Fluid" message was displayed, and other unknown warning lights were illuminated. The contact added brake fluid to the vehicle. The contact stated that she turned off and restarted the vehicle. The dealer was notified of the failure and advised the contact to take the vehicle to their location for a diagnostic test. A tow truck driver informed the contact that the brake caliper was fractured and there was a puddle of brake fluid on the ground. The vehicle was towed to the dealer, where it was diagnosed that the brakes hardware had failed, the brake caliper was fractured, and the brake sensor and actuator had failed. The dealer then informed the contact that the manufacturer was contacted and advised that they would only cover the brake caliper, pads, and rotors replacement. The vehicle was not repaired. The failure mileage was approximately 40,000.

I was driving at nighttime and my head lights cut off.. they were in auto light mode. I read that gmc knows about some sort of issue with this but only covers repairs up to 150k miles. My car is 156k miles. There was no warning lights and no indication anything was wrong. Luckily I was the only care on my side of the highway and was able to slam on the brakes and come to a complete stop. I turned the car off and then turned the head lights to manual and they can back on. A few hours later when I got home, I let the car cool off and turned the headlight back to auto and turned the car on and the worked.

Brake booster failure detected by rumbling sound during braking and certified gmc tech advised of brake booster failure on a 2019 gmc terrain with only 24k miles.

Accelerating from a stopped position into a busy intersection heard a loud clunk come from engine bay resulting in immediate "Reduced engine power" warning and stall condition. Was able to push vehicle onto the side of the road. Engine would not restart and a tow truck was called. Vehicle towed to local dealership who discovered that Vacuum Pump had failed resulting in sheering off of the exhaust camshaft. Dealers recommended fix was to replace vacuum pump and camshaft at around $4,000 but could not guarantee no debris had gotten into valve body resulting in engine failure so stated they could replace with used engine for 8500. Second vacuum pump to blow on this vehicle, first at 35k miles and replaced under warranty, this incident at just under 80k miles. Could not afford repairs and vehicle has sat for nearly 2.5 years. Contacted GM many times over that time period to get no assistance, only the offer of a small discount on a new vehicle. This incident could have proven fatal if happening at highway speeds since it stalls engine out and makes braking nearly impossible. Both GM and the NHSTA have really flunked on this one, should have been recalled during first complaints in 2020. I will continue to file complaints here on NHSTA and with GM until the cows come home.

While driving at the speed limit on U.S. Interstate 83 in Pennsylvania, my 2019 GMC Terrain's braking system suddenly, without any warning, became severely limited. The brake pedal suddenly became very hard to press and the my ability to slow or stop the vehicle became very difficult, requiring a great deal of pressure to even slow the vehicle. The braking system worked perfectly until that moment. If I needed to stop quickly or if I did not have as much leg strength, it is highly likely the equipment failure would have directly resulted in a catastrophic crash. I struggled to get the vehicle safely off the road and stopped. I then had it taken to a certified auto mechanic shop. There, it was found the GM vacuum brake booster pump had inexplicably failed, making the "brake assist" function inoperable. The mechanic was surprised GM had a replacement pump in stock, as he said that is not the norm for other brands. A moment after pressing the brake for the first time as the incident began, a message appeared on the dash stating "Service Brake Assist." There was no pre-failure warning or symptoms. I was in the middle of a 300-mile road trip, having already completed about 220 miles that day, without any notable incident. The cost to replace and install the vacuum pump was about $640.

My car automatic transmission is acting up when shifting from gear 5-6. It slips and it feels like the car is on Neutral for few seconds ( the engine RPM goes up to more than 4000 RPM)after it shifts to the 6th gear. When It shifts it feels like somebody hit us from the back. This is happening in internal roads, intermittently and on speed around 30mph. I'm worried this will cause the cars behind us to hit us when it happens. Everytime it occurs my baby starts crying. I'm concern about the safety of my family when we drive this car. I took the car to the dealership multiple times and they said that there's nothing wrong with the car.

I bought this car a couple of months ago. This problem didn't happen when I took it on a test drive from dealership. It happened after I bought it. Specifically when I start driving it more often. Sometimes a slipping occurs when shifting between gears 5-6. This happens intermittently on internal roads, not at high speed. When the car shifts the RPM goes up to 4000 RPM, sometimes even more, it feels like the car is in neutral for a few seconds, before it switches to the 6th gear. I have to remove my foot from the gas pedal to not let the RPM get very high. When this happens it feels like somebody hit us from the back. Last time my baby started crying when this happens. I'm a little concerned about our safety when we drive this car. The issue is that this problem is difficult to duplicate. Sometimes it happens more than once in 1 day and sometimes it doesn't happen for a while. I did some research online about similar cases with GM SUVs and some said that their problem was resolved after changing a defective valve Body and TCM and some said it's the clutch. It also can be transmission fluid but this car has a low mileage (28500) I doubt the transmission fluid need to be changed. Based on the GMC maintenance schedule, the transmission oil should be changed when this car reaches 45k. I took this car to the dealership multiple times, they check it and they tell me that they're unable to duplicate this issue. I'm not sure what else to do! I love this car. I'm disappointed that I had to deal with this issue that I believe is a safety hazard and could cause accidents. I need your help please!

I’m crying out to you because I bought a 2019 GMC Terrain in April of this year with about 14,000 miles. The suv ran great for about 2 months and since then I’ve been dealing with nothing but a nightmare. We’re dealing with a situation where the suv goes into park while driving. We’ve brought the suv multiple times to GMC dealership and even reached out to GMC, and had no luck resolving the issue. Last night, while driving to a family event, the suv went into park while I was driving. This is the 4th time since we got the suv. I’m scared for my safely in this suv, if you could please assist

The vehicle was returned to Hertz leasing company who later informed the contact's client that the vehicle had been diagnosed with brake vacuum pump failure. There was no further information provided. The manufacturer was not notified of the failure. The failure mileage was approximately 42,000.

Brakes failed on my car while driving and ran through 4 way stop. Took car to dealership and was told the vacuum pump seized up and sheared off. Asked the dealership what caused the problem and all they could say was normal wear and tear of the vehicle. Dealership called and said it was going to cost $900 dollars to fix the problem. I asked what that included and they said a new vacuum pump and to clean the motor out. Picked the car up on Monday and by Tuesday evening car would not run. Took it back to the dealership and am now told I need a new cam shaft which cost another $2400 to fix. This is a serious safety concern as I had no warning or received no notification that the brakes had failed just went to stop and could not. How long is GMC going to let this issue go before being addressed. How many people have to die first before they recall them as the have already recalled the bigger models of gmc, Chevrolet, Cadillac and Buick for the same reason? I don’t know how people are suppose to afford to fix an almost brand new vehicle that they are still making payments on.. Something should be done ASAP...
