The contact owns a 2007 Chevrolet Tahoe. The contact stated while driving at an unknown speed, the vehicle was having transmission failure. The vehicle was taken to the dealer however, the mechanic failed to perform a diagnostic test. The contact was informed that the transmission needed to be replaced. The vehicle was repaired however, the failure recurred. The contact stated that the gear shifter failed to shift into the park and remained neutral. Additionally, while the brake pedal was depressed, and the parking brake was engaged the vehicle was rolling backward. The manufacturer was not notified of the failure. The approximate failure mileage was 247,790.

The number 1 cylinder keeps fouling out spark plugs. I have changed plugs, wires, and the coil pack. This fixes the problem for about 5 miles. It runs poorly, low idle, the stability trac comes on and says it is malfunctioning and needs to be serviced

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.

I have been dealing with the same problem as the previous complaint...ironically, my vehicle was manufactured in tx too, but, I purchased it used in va in 2011 odometer-73,625. To date, I only have 101,225- I started having constant stabilitrack/traction control issues right after 100,000- caused steering wheel to lock up and loss of power in addition to door locks suddenly locking/unlocking, car alarm going off, and hazard blinkers not working (all while in the middle of rush hour traffic)! after this constant issue was "repaired"-for 6th time, a few months later, I experienced a different problem. After waiting at a stop light, the vehicle would not accelerate-I had to push gas all the way to the floor, barely reaching 20mph, then, the car started shaking & to make matters worse, the brakes were barely working. Thankfully, I was near a parking lot & was able to pull over. This time I think it is a BCM or pcs issue. It seems the "flex-fuel" 4WD 2007 Tahoe are having major issues. This should be constitute under lemon law. I am too scared to drive now-the car has been sitting in my driveway for a long time, yet I have to pay insurance & registration. I'm sick of wasting money as well. Please help us (2007 Tahoe owners), fix these issues! thank you.

Transmission 3 to 4 gear pack went out.

Sometimes the stable track system comes on and goes off causing the transmission and carter jerk and steer poorly too many complaints about this needs to be taken care

After approximately 3 weeks after purchasing I notice a noise and a delay in gear shifts so I took it to the dealership and they had their mechanic look at it and came up with the transmission was bad so they ordered one and tried to install it and when I went to pick it up and drove it several days the same problem was there so I took it back and they continued to try and fix it two other times within 3 months now saying I went over my 10,000 miles so I need to pay for the transmission. I drive the car maybe 5 months and the other months it has been in the shop.

Transmission is not shifting and I see that tens of thousands of people are with the same problem on the particularly SUV 2007 Chevy Tahoe this transmission should be a recall or at least fix it with a low price of less than $500 so we can keep buying these trucks

My strabilitrak and service traction control began flashing on and caused the brake lights to turn off. Then it reads, engine power is reduced. This began in November 201. I have taken it three times to be fixed. First I was told it was the throttle body, then a switch gear, then a fuel induction cleaning service. It is still happening, just twice this week. The engine slowing down while on the freeway proves to be deadly. In reviewing comments in the chevroletforum.com many consumers are having the same issues with the same results (a guessing game) why isn't this a recall?

My 2007 Tahoe all of the sudden started shaking and bucking while driving with my wife and two small kids (on valentines! wife was not happy). The service engine light came on as well as warning messages saying the traction control failed, check brake system and service stabilink system. It limped to our house and then it stalled and eventually was very hard to start. I took it to the dealership next morning and was told that the #6 lifter collapsed and they needed to check the camshaft to see if that was damaged. I'm still waiting on the call to see what the total damage is but I was told it was the active fuel management system. I also saw a lot of people's complaints online of the same thing. GM needs to own up and recall this issue. The estimate I got was around $3,500-$4,500 to repair this.

Rear end went out at 150K. Dash cracked near passenger airbag radio don't work if it's raining

I was driving down the road and I lost all power and all my lights came on on my dash I just about got hit from behind

While driving or idling, vehicle displays error messages stating "reduced engine power", "stabilitrak system disabled" and "service traction control." The engine power reduces and the vehicle hesitates upon acceleration. It is difficult to get the vehicle to accelerate, especially in lower gears. Sometimes the vehicle completely loses power in the middle of driving and all control of the vehicle is lost. This has occurred both on city streets and major highways. Purchased the vehicle used about 5 months ago and it began doing this at after about two weeks of ownership. Took it to a Chevrolet dealership and they said the throttle body was sticking and needed to be replaced. The problem seems to be getting worse over the last few weeks. The vehicle is now stalling on a regular basis (about 1-3 times every time it is driven). The problem is worse when it rains a lot outside. I am afraid to drive the vehicle with my children inside because I have lost power on in the middle of a major interstate twice.

1. lift gate failed and hurt my arm on or about Jan 1 2014. I need repaired asap! 2. dashboard cracked above steering column and cracked by air bag passenger side. I need repaired asap. GM refused to acknowledge thousands of consumers having the same effects to their dashboard. 3. timing chain went off time and bent a cylinder which caused serious damage 9/2014 cost of damages at approximate $4500 GM refused to acknowledge deficiencies. I paid out of pocket the $4500 with no assistance. I also paid $250 for estimates at the GM dealer in kingston mass. They refused to help and give assistance on any of these 3 major safety problems after submitting the dealer bona fide report.

- Centerville, MA, USA

I have 3 issues. Low power which read a lot of people have the same issue (bad torque converter).bad oil loss. Which everyone seems to have.which the won't fix. Transmission slipping which everyone is having and is not the transmission it's electrical. I was told to send a complaint in to you guys. I have read alot on this car and these are very common problems with the 07 Tahoe and I have all 3.

I was driving in the snow going 5mph and the tires began to spin. The car was in automatic for 4 wheel drive but did not kick into 4 wheel drive so I slid off the road. I was off road on a slight incline and the car wouldnt go into 4 wheel drive. It said service 4 wheel drive and the knob will turn but the 4 wheel drive will not activate. Nothing happened other than the car not going to 4 wheel drive when the knob has been turned.

My 2007 Tahoe sputtered and hesitated as I approached a stop sign. As I stopped stability control / traction control dashlights appeared as well as the check engine, they both blinked and dash read service stabilitrak, and service traction control. As I pulled from stop sign the tranny slammed into 2nd gear with a bang and I was barely accelerating pulled over and shut the car off. When I tried to restart it just turned over. It took a few tries to get it to start, and when it did I smelled a strong smell of unburned fuel from the exhaust. I will contact GM to file complaint as my Tahoe has only 97K on it. Hopefully it's covered by warranty.

Front differential started making a very loud noise. It became even louder in 4-wheel drive. While in 4-wheel drive the vehicle didn't feel right. I brought to the dealer who stated water got into the differential, and it had to be rebuilt. This is the 3rd time I have had an issue with the front differential. All 3 times, including this one, was due to the failure of the pinion seal. The first repair on 11/06/09 was covered under gms manufacturers factory warranty. The next 2 repairs, including this one, cost me a total of $1,435.49. I can only wonder how dangerous it was driving around in 4 wheel drive with a differential that was ready to catastrophically fail?

- Saint John, IN, USA

The forward sprag unit broke which ended up not only causing the vehicle to come out of drive while we were driving but also caused significant enough damage to the transmission to requite an entire rebuild. Faulty transmissions are a very common issue with this vehicle and because the company refuses to back their products and recall the issue, it ends up becoming a huge financial burden on a family. Thankfully there was no one following directly behind us when this happened or it could have been much worse. Chevrolet needs to take note and stand behind their products. Consumers have a right to expect a quality vehicle that should last well beyond 100K miles without requiring this kind of major repair.
