I took my vechile for a recall, and they found it also had a cracked exhaust manifold. After researching on the internet I found that this is a very common problem with the gm 2. 4 engine. Why hasn't a recall been issued for this problem, I would call this a serious safety issue as exhaust gasses can enter the vechile from the crack.
11/9/2020 the engine light came on and the car randomly died so I had to have it towed to the dealership. They replaced both intake and cam sol valves , replaced the exhaust manifold, both ho2 sensors, heat shield, cat converter and high pressure fuel pump. This was all done at 121617 miles. Had no issues until 125,400 on 2/3/2021 the car randomly died while driving but I made it to work. On the way to get it checked out it made a loud noise and died resulting in being pulled out of the street and to the shop. They informed me that the timing chain came apart and the engine now needs to be replaced. It's 400 miles out of the extended warranty and the repairs in November totaled $3023. 17 of which I had to pay $1,100 and now the car is inoperable and they want $7000 to install a new engine. I have found since this happened that this is a common problem that gm is aware of with the 4 cylinder engine. I kept up with oil changes and used synthetic oil.
Started having a noise both cold and hot, had it inspected to find out the exchaust manifold is cracked broken in several areas and exchaust flex pipe is bad. Car has just over 100000 miles on it. These are around the area of the catalytic converts. Gm says not under warranty I have been told this is a common problem with all 2. 4 4 cylinder.
I left the house and the engine started making loud jack hammer noises, the warning light flashed engine power reduced . The temperature outside was below zero that day , however, I had no other warning lights on my dash before the engine power reduced light . The engine suddenly became very very loud and stopped functioning. I called a tow truck and had the vehicle towed to a local mechanic, I was told that the rear manifold failed and "blew" out of the vehicle . Upon review of the website carcomplainta. Com I discovered that for my year, make and model this is a common issue that I was unaware of . There is a gm service bulletin 14882 that covers this issue and that I needed to file a complaint with you . I was told that the entire engine would need to be replaced immediately. I have no way to afford this and if gm is aware of this situation they need to make the needed repairs.
Cracked exhaust manifold which damaged oxygen sensor. Replaced by midas @ 132,863 miles 11/14/2017 total cost $664. 39.
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.
