2007 Chevrolet Tahoe: misfire or rough idle

Filed Jun 23, 2020 · Driver assistance, Engine · 189,010 miles · KY

My issues started almost two years ago when dropping my child off at daycare. I was on the highway and noticed a loud ticking noise coming from the engine. At first I was not sure what it was until I pulled in the daycare and it was evident something was wrong. At that point the stablitrak and traction control light started flashing. I had to have the vehicle towed because I tried to move it and when I put it in gear it jerked so hard I was scared the engine blew. I took it to the certified chevy mechanic, cylinder 6 misfire. We replaced the plugs, coil packs etc, trying to see what the issue could be. He finally replaced all 16 lifters, cam, head gaskets and oil pump as well. Once he got it together, it was still a misfire on cylinder 6. He took it apart to look at the pistons, they were fine. The top of the motor he practically everything brand new on it. The chevy dealership are aware of the lifter issues with this vehicle and blatantly told me, I need a new engine or could purchase a new vehicle. Still no resolve as of june 23, 2020! Please issue a recall on this as so many of these vehicles have this issue and it's not fair to us that they designed the engine so poorly.

My 2007 chevrolet tahoe will sporadically display two m.I.l. 's - service traction control and service stabilitrak. I have spent close to $4,000 on different parts, as well as having the heads completely rebuilt about 5 months ago. The only trouble codes it shows when hooked to a scanner are a p0300 (generic misfire detected) p0301 (misfire cylinder 1) and 0443 (evap emission control system valve circuit). After several months of research online, it is blatantly obvious that there are several thousand people experiencing the exact same issues. It appears there is no direct surefire resolution. But rather a common occurrence that is sometimes very labor intensive and extremely invasive to track down the specific problem. I have replaced the brake light control switch, added a secondary backup battery as well as additional positive and negative cables, replace the plugs, plug wires and ignition coil packs. It seems to be a recurring issue and at this point I have as much money invested in repairing the vehicle as I have spent purchasing it. I am not the type of person to sell this truck and let's have the misfortune of dealing with such issues but after several thousand dollars spent and discovering that it is a very common problem amongst chevrolet / gm suvs and trucks, particularly with the 5.3 l engine, I feel general motors should at least cover the expense of repairing it or let me trade it in towards a newer model with a sufficient credit applied. The issues I'm experiencing seem to happen when I am stopping or accelerating above 40 miles per hour. If I am simply cruising along at 25 miles per hour steadily and not accelerating or breaking, it doesn't seem to be as prevalent. But as previously stated, it is sporadic and continues to reoccur incessantly.

My car has been in the shop for 7 weeks. I've spent $6,000 having the engine rebuilt as there was cylinder 7 misfire. However, after all this I'm still getting the same error codes and they now believe its electrical and the whole car needs to be re-wired. When it broke down originally, it was in neutral in a car wash...

Oil consumption of at least a quart between oil changes, misfiring at idle causing check engine light, stability track control service light. Chevrolet tells me there is not even 1 service bulletin or recall notice on my tahoe.

Tl*the contact owns a 2007 chevrolet tahoe. The contact stated while driving at various speeds her v-8 engine should switch to a v-4 whenever she increased her speed to save on gasoline. The vehicle was inspected by a dealer who advised her that the vehicle was stuck in v-8 and caused the vehicle to misfire. The 8 lifters, manifold, and all of the gaskets surrounding them were repaired. The failure mileage was approximately 130,000.
