general problems of the 2013 GMC Terrain

Vehicle started running rough when driven, mechanic found fuel pump putting fuel into oil. Could have caught fire! pump replaced and trashed. Check engine light was only warning other then rought running engine.

The engine locked up due to oil leaking into it. This is a known issue with gm on these model cars but instead of issuing a recall they issued a special warranty that expired leaving consumers with these vehicles to be responsible for this repair which cost over $8,000.

When refueling, and having the fill nozzle locked on for auto shutoff, the fuel overflows and drains out of the fuel fill cavity and drips on the right rear tire. This usually results in gasoline smell in the car. This happens on most fuel nozzles. I should have reported it years ago.

When driving vehicle loses power, upon pushing accelerator there is no acceleration and vehicle keeps losing speed. This happens at any given time.

The exhaust and emissions system appears to have failed or is malfunctioning, including the catalytic converter and potentially the exhaust manifold or upstream exhaust components. The engine and fuel/propulsion system are also affected, as evidenced by sputtering and drivability issues. The vehicle and affected components are available for inspection upon request. Exhaust and/or fuel fumes enter the passenger cabin, particularly when the heater or air conditioning is operating. This creates a risk of exposure to harmful exhaust gases, including potential carbon monoxide, which poses a serious health and safety risk to vehicle occupants. The vehicle also sputters and hesitates, which could lead to unsafe driving conditions, especially in traffic or at highway speeds. Yes. The issue has been confirmed through diagnostic trouble codes indicating catalytic converter efficiency failure. Despite replacement of spark plugs and sensors, the problem continues to recur, indicating an underlying exhaust or emissions system defect rather than routine maintenance. The vehicle has been inspected by service professionals for diagnostic purposes. The manufacturer has not physically inspected the vehicle, and no inspections have been performed by police or insurance representatives to date. The check engine light illuminated prior to and during the issue. Additional symptoms included engine sputtering, loss of smooth acceleration, and a strong exhaust or fuel odor inside the cabin when the hvac system is in use. These symptoms have recurred over time despite repairs.

While driving on the highway at speed limit 75mph, the vehicle (without warning ??) 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.

Hello, I have spent a lot of money on this mobile car and even so, it continues to cause problems and the oil runs out too quickly.

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.

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.

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.

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.

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 smooths 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.
