While driving on the highway at speed limit 75mph, the vehicle (without warning -š ï¸) suddenly went into (Reduced Power Engine Mode/ Service Stabilitrack) jerked and slowed down to 35mp almost causing a pile up as cars behind and next to me where still driving above 70mph. If not for my quick reaction to turn on emergency lights cars behind me would have hit me. Immediately after I got off the highway I drove the car (at 35mph as fast as it went) to my nearest Pepboys. Here the vehicle was serviced for nearly a month until the problem was fixed. The cost was almost $6500 GMC has failed to notify customers if this potential issue which not only risks the lives of the drivers and passengers of the 2013 Terrain but those driving alongside it. This is not a new issue as I found the testimonies of many other GMC owners tell a similar dangerous experience. Please help! I have detailed invoices of the repairs.
I've been having same issues Occurring since I Signed my purchase agreement. The constant rattle at about 1500 RPM, The oil leaves At such a rapid rate That I have to monitor it every day As to make sure the level doesn't go too low. I've only had the vehicle since September 2022 and here it is Halloween 2022 and I'm down over $2000 maintenance costs and maintenance costs trying to prevent catastrophic failure with the engine that I know is coming! OBDII code reads P0171
Vehicle burns excessive amounts of oil. I need to add oil almost every time I drive. This could result in catastrophic engine failure. GMC and Chevrolet know about this problem, but refuse to issue a recall for this engine.
I-€™ve been having a issue with my oil consumption and display messages about servicing the stabilitrak and traction control. I could be driving and suddenly my engine power is reduced asking with these two messages. I received a letter from GMC about the excessive oil consumption due to degraded catalytic converter and/or oxygen sensor. The one oxygen sensor was replaced before I received the letter. The letter states I should get the oil consumption diagnosed. I-€™ve went 4 times now and the oil dipstick smells like gas but the dealership is saying the special coverage has expired. My letter says otherwise. Why send a letter about a possible issue and then not help to fix it?

Iin early 2020 I reached out to 2 different GMC dealerships in regard to the recalls that existed on my vehicle's engine and oil consumption. The vehicle was overconsuming oil (I would track the oil levels) and needed excessive oil changes. The first dealership said that my vehicle didn't qualify for the recall due to mileage when I just received the recall notice. Second dealership wouldn't even look at vehicle. A few months later the engine blew, spilling oil everywhere. The engine now needs a total engine replacement. Had the dealerships agreed to look at the oil consumption issues the vehicle was having and had knowledge of the GMC recalls on the vehicle, I wouldn't have an inoperable vehicle and needed to purchase a new vehicle due to the engine issues not being covered that were common knowledge on these make/model/year vehicles. I have tried to work with dealerships as well as my the financer of the vehicle, GMC needs to acknowledge this issue and contact me. Since the warranty ended on the vehicle the 1st year I owned it, I have put nearly $10,000 into faulty parts and replacements on the vehicle that weren't "covered". I would like this situation investigated due to the safety issues the engine caused that were refused to be looked at and now the negative financial aspect it has caused me.
My car began making odd knocking sounds and since it was due for an oil change, I made an appointment. The day of the appointment, as I was driving down a busy street and the car locked up and quit. I pulled into a driveway and called aaa. I tried turning the vehicle on a couple of times and it made a significantly loud noise that was concerning. After a mechanic assessed what was wrong, it was determined that the timing chain needed to be replaced and the car was nearly out of oil, even though it had not been 3,000 miles since the last oil change. The repair cost over $2,000.
Engine power reduced light came on and there is rattling noise under the hood. We pulled out of a drive thru into oncoming traffic when this all started.
The rear main seal on the engine blew out while driving due to the PCV system being faulty. My car died in the middle of a busy intersection without warning in 10 degree weather with negative 10 degree windchill, leaving my family and stranded without the ability to even get heat into the car.
There are several issues with this vehicle which makes me think this car was a lemon, unreported by original owner, or in a flood; 1st, the rear hatch struts were totally rusted out and inoperable (reinforcing my flood thought.) 2nd, the vehicles mpg is nowhere near the advertised 22/32 - I mentioned my concern several times to the service dept, the sales man, and the certified sale manager; their solution - they reset the gauge on the dashboard! 3rd, within days of my purchase, I noticed a knock under my car that sounded like an axle was going to bust through my floorboard it was knocking so hard! after numerous service repair attempts & visits back to the dealer, one visit lasting approximately 7 days, they think they've fixed the problem. Secondary fuel tank fuel pump module - (contributing to fuel consumption issue?) 4th, the windshield wipers stopped working while I was driving to work, in the fast lane, @ 6am one dark, rainy morning, during a torrential down pour almost causing a major pile up! 5th, check engine light, stumbles and misfires on acceleration, shuts off when stopped at a stop sign or traffic light. Repaired/several hundred dollars later. 6th, the continuing issues have been, but not limited to reduced engine power, rough idle, engine sputters, hesitates, poor gas mileage, & excessive oil consumption. 7th, another check engine light, now fuel-injectors need replaced (another contributor to fuel consumption issue?). after further review of the vehicle's cpo paperwork, this is not the certified vehicle being referred to on the paperwork. There are items checked off on the report that do not apply to this vehicle. I would have never overpaid for a cpo vehicle had I know their "rigorous standards" meant absolutely nothing! I have bought many cars in my life, both new and used cars and never had any of the issues I am having with this vehicle!
We live in California and the carb fuel pump nozzles are cumbersome beasts. But the nozzle pops out of the fuel filler when placed on auto-fill at 4 out of 5 gas stations. It's dangerous when it pops out and falls on the ground sometimes pumping gas all over. I took the Terrain to the dealer and of cource they can't find anything wrong with it. What gives and what's the fix?
The contact owns a 2013 GMC Terrain. While driving approximately 30 mph, the contact noticed a fuel odor. The contact also noticed that the fuel gauge was lowering. The contact exited the vehicle and noticed a puddle underneath. The vehicle was taken to a dealer where it was diagnosed that the fuel line needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 18,000. Updated 09/27/16
I was about to switch lanes on highway from on ramp travelling aprpox 60 mph and accelerating when my vehicle suddeling stopped accelerating & someone pulled up on my side to inform me I was leaking fuel everywhere. I lost nearly a full tank of gas on the highway. One of the men who stopped had worked on GM vehicles in the past and was able to clip something together to slow the leak. I drove to the dealership and they were no help and didn't seem to care about the issue or how serious this was for a 2 year old car with 37K miles. I was told I was out of warranty and they would not do anything for me and were going to charge me a $200 diagnostic fee. Disappointed by the poor service I received I took the car to my local mechanic who works on our other vehicle. They were shocked to see a fuel line on a 2013 vehicle break. They ordered the replacement fuel line from GM and I got my car back on 5 days later. The next day I took my car out to run errands and when returning to the vehicle I noticed a strong smell of gas, upon looking under the car I noticed that the fuel line was still leaking and from the same place! we brought the vehicle back to the shop and they immediately go in touch with GM who sent out another replacement part and also recommended also replacing the metal line as they had been seeing some issues with this line. Under the recommendation of GM the shop replaced both lines and I got my car back 3 days later. The problems I have experienced are unacceptable and could be very dangerous. Fortunately no one was hurt but had I been in the high speed lane and traveling at full speed limit when this happen I or someone else could have been seriously injured by this issue. Given the age of the car and low mileage this is not a wear and tear issue, this is 100% a defective part or mfg problem that I expect GM to reimburse $670 for repair.
Less than a month ago, while driving on interstate 95 in the left lane during rush hour the engine blew on a 2 year old GMC Terrain. How this is at all possible I have no clue, but luckily enough I was able to safely coast over to the right shoulder and await for a tow truck. Below is the background information, as well as the headache I have had to undergo since this happened. -1 month prior to the engine being blown I had taken the car in for a 5,000 mile check-up -night before the incident there was a fluttering noise heard from the engine, so planned on taking to sheehan the next morning at approximately 9:30 am on 3/17/2015 was driving on interstate 95 in the left lane during rush hour and the rpms dropped to zero -witness something that looked like oil leaking from the engine was told to sheehan Buick GMC where they looked at it and the next day reported that the engine blew, a rod to the piston snapped and tore a hole through the side of the engine -was told by service manager that when the engine went it "grenade" inside and resulted in longer to fix and replacing more parts like a manifold. -since it was fixed I had no other choice but to take the car back I left the shop and got on interstate 95 for about 10 miles when I noticed the check-engine light on immediately returned to sheehan and took the loaner back -was told now had to replace the fuel injectors -2 weeks after that week repaid engine light on again for a wire harness.
When the GMC Terrain is first started in the mornings the vehicle "misses" for about 5 seconds. It sounds like there is condensation in the fuel line. After about 5 seconds the vehicle smoothes out and runs normal. This happens almost each and every morning. It does not happen any other time.
Road dirt, snow, mud accumulates at inside bottoms of doors all the way up to bottom of speaker areas. I can see where it is pulling down the bottom panels. Called dealer and asked for GM info on this and nothing back from dealer. Also 2 weeks ago engine lite came on, took to local dealer for replacement of gasoline sensor" at 10,000 miles? asked if I used corn gas? no, I use plus or premium. Does this happen every 10,000 miles" also I am concerned I will have rust on my doors very soon.
