2019 GMC TERRAIN Power Train Problems

Drove car approximately 15 miles. Parked car. Car would not turn off. Message- Transmission/Park. Wouldn't Car stayed neutral. Had to call wecker to take dealership. ... Diagnostic Solenoid Valve Body faulty.... 2019 Terrain Miles 91669. Is there recall. Have more reports of issue. Should this happen with a well maintained vehicle All maintenance updated to date.

I bought this Terrain brand new from Betten Baker Chevrolet in Muskegon Mi in 2019 with 500 miles. That same year we had transmission Slippage causing it to slip out of gear then slam back into gear while driving. I took it to the dealer to have it looked at. They did nothing and informed me it was known by the manufacturer that this was an issue. I then had to bring it back for electrical issues as the lights would all start going off in the cab including dome lights and shift buttons. All key fob would not be recognized by the car and would have to be reprogrammed counting 5 times now. Now I am sitting at just oflver 100,000 miles and what I thought was going to be a simple spark plug change gas turned into a complete motor failure. did an oil change and there was no oil in it. The turbo was replaced and now the engine started making a lot of rattling noises and just stopped. the dash says service transmission, ECS, Extremely low battery voltage and has jost die after oil started pouring out the bottom of the car. It is now sitting at the dealership service department where I was told by am employee there that they have been seeing them come in at 150,000 miles for complete rebuilds and mine was early. let me tell you that this car isn't even paid off yet. And the 2006 Ram 1500 is more reliable.

Vehicle struggles to shift from low gears; seems to completely miss 3rd gear. Codes from maintenance indicate TCC slip

While working out of town for work my engine light started flashing and the dash lights went nuts. My brakes were nonexistent and were hard as a rock. I had zero warning as to what happened. Working 3 hours away from home the car had to be towed and I was informed the engine code came back as my cam shaft. Took it to the dealer as Gm has a bulletin put out. I didn’t know what that meant. Long story short and 3000.00 dollars later I find out that the vacuum pump exploded which cause the cam shaft to fail. I was out of work for almost a month. There is a recall for almost all vehicles from this year but not the 2019 terrain even though it contains the same vacuum pump as all the recalled makes and models. Vacuum pump, cam shaft, oil pan, oil pump had to all be replaced at under 100,000 highway miles. Someone needs to address this problem.

The GMC Terrain P187E transmission code indicates a problem with the transmission senor or shift interlock. It prevented our car from shifting into park. The car won't start now. We had to disconnect the battery because the car would not stop beeping. Milage is only 22000 miles and we have owned it for less then 2 months. It is a 9 speed transmission which I understand this to be an on going issue with this transmission.

Brake vacuum pump premature failure. As you see GMC, terrains, in Equinox, I have an issue, while the engine it's on while driving etc, if this bark fails, you will have an issue I'm trying to stop. This is a known problem or GM. And as of now, they have not come out with a solution or a recall for this problem. This problem has caused many customers. To lose thousands of dollars, he repairs. I'm not covered by the warranty. This should be addressed and repaired as soon as possible as it may cause someone else to lose their life. Second problem is the 9 speed transmission transmission lack power when trying to gain speed as you enter the highway. Lastly they blamed the selenoids etc. Lastly the pulley belt retention broke down premature with only 68k miles. This is an ongoing problem gm is well aware and tries to hide or fix. When someone buys a vehicle we expect to last longer than 100k 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.

The contact owns a 2019 GMC Terrain. The contact stated upon taking the vehicle to the Nissan dealer where it was purchased for an oil change, the dealer informed the contact that there was a crack in the transmission. The vehicle was then taken to a GMC dealer, where the contact was informed that the crack was more than two months old. The dealer determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 38,700.

Mileage: 38,700

The contact owns a 2019 GMC Terrain. The contact stated that occasionally while driving at various speeds, the vehicle independently shifted into neutral(N) and the vehicle lost motive power while the accelerator pedal was depressed. In addition, the vehicle had shifted from park(P) to drive(D) and into neutral(N). There was no warning light illuminated. The vehicle was taken to a local dealer, where it was diagnosed; however, the cause of the failure was not identified. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 45,000.

Mileage: 45,000

While driving the car went into power save mode and completely shut down. There were no prior lights or warnings that the car was having issues. While driving at 45mph on a busy road it just suddenly shut down. It would not move to get it out of the road. I was almost hit from behind. After the car was towed, it was diagnosed as a broken vacuum pump and exhaust camshaft. Our Terrain only has 67,773 miles at the time of the incident which was unfortunately just outside of warranty. Since this incident and the repair, the car has had to go back to the shop 4 times. It is still not driving correctly and stalled as I pulled out onto a main road almost causing an accident. Still working on getting it diagnosed and repaired correctly. The mechanics I have spoken to indicated this engine/car is known for these issues. Without any warning lights or signs of issues prior it really put us in a dangerous situation.

Driving home from dropping my daughter off at school. When slowing down at stop sign, car locked up brakes completely, almost went through stop sign, car shut down engine and placed vehicle in park. Diagnosis is a vacuum pump failure, causing reluctor wheel to spin freely from camshaft. This happened without warning at 70k miles. Diagnostic report from three weeks prior showed no bad diagnostics with engine or drivetrain components, or brake components. Had to have car towed from intersection where i was impeding traffic due to sudden failure. Garage is concerned regarding potential for debris and engine damage, as well as timing issues due to sudden failure of vacuum pump. GM has authorized vacuum pump recalls on other makes from prior years, not Terrain for some reason. This is how becoming highly reported failure among GMC/Chevy vehicles with shaft driven vacuum pump design between 2019-2022. GM has stopped using this design on 23 and newer models. They should absolutely recall these older models for this issue. Sudden vacuum pump failure can lead to unrepairable engine damage due to design.

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

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.

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.

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.

jerking at times while driving.

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

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.

Mileage: 60,000

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

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.

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.

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!

Transmission slips from cold start No. Have not taken to Dealer No. No. Warning lights or messages

The car failed to shift into gear. Message displayed, "transmission unable to shift" ,"2 gears selected " or "service transmission". Issued started in June 2022 while in drive thru line, when shifting from park to move the car would not shift. Had to turn car off for about 10 minutes and car was able to shift and drive normal. Check engine light came on about a week later and had checked for code p07b5. A couple of days later, light went back off. About 3 days later getting ready to leave home and car would not shift into gear again but turn car off and back on a couple of times and car shifted and drove normal. On July 13 2022 was driving in traffic and message displayed, unable to shift and service transmission. When I changed lanes and released the gas petal, the car went into park, stopped, and set the parking brakes, but did not turn off, jerking me forward and throwing things around in the car. Cars behind me had to slam on brakes to keep from hitting me because there was no initial brake light. I put on the flashers and turned the car off. Parking brake was stuck so I pressed it about 5 times before it finally released. I restarted the car 3 times and it finally shifted and drove as normal. I called gm to inquiry about a recall and was told there were none. I called for a diagnostic test and schedule is in about 2 weeks. The car has not been inspected by anyone listed above?⁸

Brakes quit working after service light came on. Vehicle will not stop

The autoshutoff of the vehicle should be optional this vehicle goes on and off so many times and after it starts is acting up on braking and transmission deeler says no dtc all good but still doin it

I received a "service brake assist" message which came on then off. Took the car to a local mechanic who looked it over and said to see dealer as they saw nothing obvious. internet search revealed that many people with terrain said this warning came on when battery was low. Made a service appt for NJ dealer for 12/6/21. on 12/3/21, began a 1200 mile drive from Florida to NJ, after 2 hours, check engine light came on. Took the exit ramp from I 75 and at end of ramp, there was a total braking failure. I had to press very hard to eventually stop. Shut off car, attempted to restart but it would not. Towed to a mechanic who found fluid leakage and a repair bulletin on GM site involving vacuum seal camshaft. #pip5598A diagnostic tip. Internet search reveals many anecdotal instances of same problem. On Monday, 12/6/21, I received an email from GMAC saying that the on board diagnostics had shown a "low battery" concern. The catastrophic loss of braking seems to be connected to a low battery situation. This needs to be looked into by NHTSA.

My 2019 GMC Terrain has 21K miles and noticed a oil or transmission leak this morning. I see recalls for other vehicles but none for mine. Linking from a bolt just as the other recall is for.

TRANSMISSION WOULD REV UP BETWEEN 4TH AND 5TH GEAR ONLY IN THE ON THE FIRST DRIVE. AFTER THAT IT WOULD SHIFT NORMALLY . WENT INTO DEKALB GMC ILLINOIS AND WAS TOLD IT WAS SOME PISTONS AND OTHER PARTS. THEY HAD IT FOR A WEEK OR TWO BECAUSE OF OTHER TRANS JOBS AHEAD ON MINE. GOT CAR BACK AND IT WAS WORKING FINE FOR A MONTH OR SO AND THEN IT STARTED TO SHIFT BAD AGAIN BETWEEN THE SAME TWO GEARS ONLY LONGER GAP BETWEEN SHIFTS THIS TIME. TOOK IT BACK TO THE DEALER AND THE TECH ORDERED MORE PARTS TO REPAIR THE TRANS AND SAID I WOULD POSSIBLY GET IT BACK ON OCTOBER 19TH BY END OF DAY. IS THIS GOING TO BE AN ONGOING PROBLEM? IF SO WHAT IS THE LAW ABOUT 3 OR MORE REPAIRS FOR THE SAME PROBLEM. THIS IS THE SECOND REPAIR SO FAR.

WHEN I SHIFT IT FROM REVERSE TO DRIVE ON A VERY SLIGHT INCLINE, THE ENGINE WILL REV AND NOT ACCELERATE AFTER I INITIALLY START MOVING FORWARD. IT ACTUALLY ALMOST COMES TO A STOP BEFORE FINALLY ACCELERATING. IT HAS NOW STARTED DOING IT WHILE DRIVING AND STALLED IN THE HIGHWAY ON 2/13. I CARRIED IT LAST YEAR FOR THE SAME ISSUE, BUT THEY TOLD ME THEY COULDN'T DUPLICATE IT. TODAY, THEY TOLD ME THE SAME THING. THEY CAN'T EXPLAIN WHY IT STALLED IN THE MIDDLE OF THE ROAD. EVEN THOUGH THE CHECK ENGINE LIGHT CAME ON AND ON-STAR TOLD ME TO CARRY IT TO A DEALER. THE SERVICE TECH GUY ALSO TOLD ME THAT MY VEHICLE HAD 67,000 MILES ON IT. IT HAS LESS THAN 30,000 (NOT SURE ON THE EXACT NUMBER SINCE IT IS STILL AT THE DEALERSHIP.) IT IS NO LONGER SAFE TO DRIVE, BUT SINCE THEY CANNOT DUPLICATE IT, THEY AREN'T EVEN GOING TO INVESTIGATE IT FURTHER.

THE VEHICLE WAS PURCHASED ON JUNE 22, 2019, WITH 19 MILES ON THE ODOMETER AND HAD 1102 MILES ON IT WHEN THE INCIDENT OCCURRED. ON 19 JULY, 2019 MY WIFE AND I WERE DRIVING ON INTERSTATE 95 NEAR THE ROCKY MOUNT EXIT WHEN I PULLED INTO THE PASSING LANE TO GO AROUND SLOWER TRAFFIC (APPROXIMATELY 70 MPH). UPON PRESSING THE ACCELERATOR THE ENGINE RPM INCREASED, BUT THE VEHICLE'S SPEED DID NOT. ALMOST IMMEDIATELY THE VEHICLE EXPERIENCED A VIOLENT SURGE (TO THE EXTENT THAT I THOUGHT I HAD BEEN REAR-ENDED) AND THE VEHICLE ACCELERATED. AT THIS POINT, WE WERE STARTLED, AND CONTINUED UNTIL EXITING NC HWY 13 WITH NO FURTHER INCIDENT OTHER THAN THE CRUISE CONTROL BECOMING INOPERATIVE AFTER THE INITIAL INCIDENT. UPON ARRIVING AT THE OUTSKIRTS OF GREENVILLE, NC WE ENCOUNTERED A RED LIGHT AND HAD TO STOP. UPON PRESSING THE ACCELERATOR, THE ENGINE RPM ONCE AGAIN INCREASED AND ANOTHER VIOLENT SURGE WAS EXPERIENCED. AT THAT POINT, WE ENTERED A GAS STATION AND CALLED ONSTAR FOR ROADSIDE ASSISTANCE. THE CAR WAS SUBSEQUENTLY TOWED TO A LOCAL DEALERSHIP (BROWN & WOOD GMC) WHERE THE ON-DUTY MECHANIC DUPLICATED THE UNSAFE CONDITION. DEALERSHIP STATED THAT THEY DID NOT KNOW WHAT WAS WRONG BECAUSE THE VEHICLE WAS SO NEW, AND THEY COULD NOT CONTACT CORPORATE UNTIL MONDAY (JULY 22). I RETURNED TO THE DEALERSHIP SATURDAY (JUL 20) TO GET A STATUS AND MAKE ARRANGEMENTS FOR A LOANER VEHICLE AND WAS INFORMED BY THE SERVICE ADVISOR THAT THE ISSUE WAS WITH THE VEHICLE WAS EVEN WORSE THAN THE DAY BEFORE - I DID NOT INQUIRE AS TO WHAT THAT MEANT BECAUSE IT WAS PRETTY UNSAFE AND SCARY TO EXPERIENCE IT THE DAY BEFORE. I WAS NOTIFIED YESTERDAY BY THE DEALERSHIP THAT THE ISSUE IS A VALVE BODY, BUT THAT THEY DID NOT KNOW HOW LONG IT WOULD TAKE TO RECEIVE THE PART.

I PURCHASED A 2019 GMC TERRAIN VIN: [XXX] ON JAN 17, 2019 AT RIZZA BUICK GMC 8415 W. 159TH STREET, TINLEY PARK IL, 60487, ON JANUARY 17, 2019. THIS WAS MY FIRST BRAND NEW CAR AND I WAS EXCITED. I TRADED IN A 2014 GMC TERRAIN IN THE PROCESS, KNOWING I WOULD BE UPSIDE DOWN ON THE LOAN. I HAD THE FIRST SERVICE DONE ON APRIL 23, 2019 AT SAID DEALERSHIP. AT THAT VISIT I EXPLAINED THAT I WAS HEARING A NOISE ON THE PASSENGER SIDE VENT EVEN WHEN THE HVAC WAS NOT RUNNING. I WAS TOLD NOTHING WAS DETECTED AND MY VEHICLE WAS FINE ON MAY 24, 2019, I DROVE MY VEHICLE TO MEMPHIS TENNESSEE WITH MY FAMILY FOR MEMORIAL DAY. ON MAY 25, 2019 THE CHECK ENGINE LIGHT CAME ON, I WAS LOSING POWER TO THE ENGINE. THAT SAME NIGHT CUSTOMER SERVICE TOWED MY VEHICLE TO SUNRISE CHEVROLET BUICK GMC, 1800 COVINGTON PIKE MEMPHIS, TENNESSEE 38128, A NEARBY GMC DEALERSHIP AND SET UP A RENTAL CAR IN THE AREA FOR ME TO DRIVE. BECAUSE IT WAS THE HOLIDAY, ENTERPRISE WAS CLOSED, AND I HAD NO VEHICLE TO DRIVE FOR TWO DAYS. THIS WAS AN INCONVENIENCE TO ME AND MY FAMILY, I HAD TO ALTER MY TRIP PLANS THAT WERE MADE BACK IN FEBRUARY 2019. ON MAY 27, 2019 I WAS TOLD BY [XXX] THE TECHNICIAN AT SUNRISE CHEVROLET THAT AIR BOX TUBE WAS LOOSE AND NOT PROPERLY INSTALLED AND COULD HAVE BEEN DONE DURING MY SERVICE I HAD DONE APRIL 23RD. I WAS ASSURED EVERYTHING WAS OKAY AND I WAS GOOD TO GO. ON MAY 31, WHILE TRAVELING BACK HOME THE CHECK ENGINE LIGHT CAME ON AGAIN. SAME MESSAGE ON THE DASH AND IT WAS RAINING AT 3AM. I WAS CLOSE TO HOME AND WAS ABLE TO MAKE IT TO THE DEALERSHIP THAT I PURCHASED IT FROM. MY VEHICLE HAS BEEN IN SERVICE SINCE MAY 31, 2019 AND I AM JUST FINDING OUT THAT I HAVE A PART THAT IS ON NATIONAL BACK ORDER. I AM NOT SATISFIED WITH MY EXPERIENCE AN I AM REACHING OUT TO YOU TO RESOLVE THIS MATTER. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

I HAVE A 2019 GMC TERRIAN WITH 2500 MILES. I WAS DRIVING IT AND THE CAR FLASHED LOW FUEL, CHECK TRANSMISSION AND CHECK ENGINE WARNING AND SHUT DOWN WHILE I WAS AS A HIGHWAY SPEED. I WAS FORTUNATELY OK, HOWEVER IT STRANDED ME AT A SPOT WITH MERGING TRAFFIC, NO SHOULDER AND NO POWER TO GET THE VEHICLE OUT OF THERE. THE VEHICLE WAS ABLE TO START UP SHORTLY, THEN I HAD TO DEAL WITH GETTING GOING AGAIN IN THIS PRECARIOUS SPOT.
