I have an 07 tahoe and have read from other people that this is happening to alot of others as well. i had my truck inspected at the chevy dealer in lake elsinore. they said it could be a number of things and thought that cleaning my intake system would fix the problem. it was fine for one day then out of nowhere driving on the freeway my stability trac light comes on and the check engine light and says reduced engine power . i had my wife and kids in the truck and find it funny that i guess this has happened to others with different vehicles but the same year gmc yukons. i had the same problem as one and they were near semi trucks. this is not good even worse when you are no longer under the warranty and the dealer can't tell you exactly what it is but wants to try everything. that is wrong. this is dangerous to have happen and even worse when the dealer wants to say they are not exactly sure but find out from reading about others vehicles like mine with the same problem and no help. *tr

I bought a 2007 tahoe with a mileage of just over 77k, the low oil light came on just as the first oil change was due(3k miles). it was approximately a quart low. the dealership i bought it it had just changed the oil so i thought, "maybe they just didnt put enough in." took it to local station that i get all my work done at to get an oil change. light came on again before the next oil change was due again almost a quart low. i put more oil in and changed again at 83086. at 86147 light came on again and was 1 1/4 qts low, so i added more oil. then at 87098 we were leaving to go on a road trip so i checked oil and it was 1/4 qt low. this appears to be a common problem for this year vehicle according to online reports. i shouldn't be having to add this much oil to the vehicle in such a short amount of mileage. *tt

Excessive oil consumption. *tr

Heavy oil consumption. the car says oil is low about every two weeks or less. *tr

Our 2007 chevrolet tahoe will not start. there have been four occasions where my family and i were getting ready to take a trip and when my husband went to turn the car on it would not start. we have had the vehicle jump started twice and have taken the car to antwerpen chevrolet twice and each time we were told that there was no real problem. it happened again an no one seems to know what the problem is, this has become a big problem for my family and unfortunately we can't seem to get any help from anyone. *tr

Tl*the contact owns a 2007 chevrolet tahoe. the vehicle had not been driven for 10 hours when a fire started under the hood and caused the front tire to explode. the entire front of the vehicle melted on the ground. the vehicle was approximately a foot from the house and as high as the two story house. after hearing the explosion, the contacts husband used a garden hose to keep the flames away from the house. an additional vehicle that belongs to the contact was damaged by the fire. there was also property damage to the siding and bricks on the house. the fire department extinguished the fire, filed a report, and stated that the cause was an electrical short. the insurance company towed the vehicle to general motors to conduct an investigation. there were no injuries. the failure and current mileages were 9000.update 09/10/08 *cw updated 09/17/08. *jb

We have had several problems with this vehicle. we've had tires replaced twice, rotors, and brakes resurfaced, and rear-end dropped so the springs could be adjusted. but the biggest problem has been with the roaring in the motor. the dealership has had the vehicle for more than 20 days on and off looking for this noise. i've had it to them 8 times or so trying to find it. the noise didn't start until around 3,000 miles, and gets worse and easier to duplicate with more miles. the first 7 visits they said they didn't know what it was and was clueless to it, but the last visit, and 4 days of it, they and gm decided it was a "characteristic" of the vehicle, and nothing could be done. on the otherhand, one mechanic says it's coming from the drivetrain, but others say it's an improper balance in the motor. either way i'm paying too much money for whatever it is! *tr

I own a new 2007 chevy tahoe that i purchased on 2/22/07 for $49k. on dec 31st, 2007 i came home from work at 3pm and parked my car in our attached garage (car obviously turned off). at 3:45pm my wife started to smell smoke -- upon entering the garage i noticed that the car was smoking (fire dept thinks its electrical in nature - definitely smelled like it was). i have not had a problem at all with this car and kept up with all maintenance only using the gm dealership for work. we immediately called the fire dept -- when the police and fire made it to the scene the engine burst into flames. my one year old son was sleeping in his room right above the garage. there are a lot of "what ifs" that go through your head if we had not smelled the smoke and the car blew up. not even taking into account that there was another car right next to the tahoe which was full of gas. gm has given me the run around and does not feel that my car deserves to be replaced. they are very happy letting my insurance pay for the damage to my house and letting me suffer a $16k loss out of pocket for this incident. i am currently pursuing legal avenues and am in the process of looking at the lemon law that massachusetts has on the books. *tr

Tl*the contact owns a 2007 chevrolet tahoe. on january 12, 2007, the check engine light illuminated intermittently. the vehicle was taken to the dealer and they reinstalled the cam shaft clip into the harness, and replaced the cam shaft position sensor. on november 21, 2007, the vehicle was taken back to the dealer because the engine light illuminated again. the cam shaft sensor was replaced again. on january 29, 2008, the engine light illuminated again and the vehicle was difficult to start. in addition, the auto start remote would not work. the dealer replaced the cam sensor again. since the last replacement, the engine light has not illuminated again. the current mileage was 16,000 and failure mileage was 10,948.

Tl*- the contact stated that while driving the 2007 chevrolet tahoe at 65 mph the vehicle began to overheat and slowed down to 25 mph. the vehicle had to be driven slowly for 20 miles off the road to safety, before being towed. there was a large hole in the generator, and the radiator had to be replaced. *ak

We took our vehicle to the dealer for a 3rd time now (look for my other complaint on this website on electrical problems/windshield problems) for the same problem plus a number of multiple other problems. the problem that the dealer can't seem to remedy is the windshield wipers and wiper spray keep coming on all by themselves and cannot be turned off unless you turn the vehicle off and then restart it. they've replaced the windshield wiper module but they still come on randomly. the heated seats sometimes don't work and in order to get them to work you must restart the car. the front passenger window will randomly not roll up or down from the drivers side master switch and will only start working after restarting the vehicle. when i took my car to get serviced (oil change) the mechanic noticed several leaks under the vehicle, one coming from the engine bell housing another from the rack and pinion area and the third from the power steering pump housing area. when we took it to the dealer they cleaned the engine pan (i have before pictures) and added an engine dye and they stated they found no leaks, we'll check it again after a few hundred miles. they also cleaned up the other leaks from the other areas and claimed no leaks. our mechanic also noticed while rotating the tires that the front right rotors were deeply grooved which answers my question as to why my brakes have been squeaking. he says that with only 10,000 miles it is not normal for them to be grooved, and is definitely a defect with the calipers probably sticking. showed the dealer and the service writer stated it was normal, that cannot be normal. so now they resurfaced the rotor and the brakes are still squeaking. after bringing my vehicle home from the dealer for repairs the car locked "itself" i did not lock it, the car keys were not even in my hands anymore they were hanging on the key rack. there are definitely some major electrical problems and mechanical problems with this vehicle. *jb

Reference: near death experiences while driving our brand new (2 week old, chevrolet tahoe ) my family and i have experienced 3 near death situations on two major interstates while driving the two week old 2007 tahoe that i purchased on may 20. i will explain the dangerous experiences we were subjected to in chevrolet tahoe. the chevrolet tahoe i just purchased 2 weeks ago has stalled on three occasions, while i was driving at 65-70 mph, on a busy interstate. when the incidents occurred there were many motorist on the interstate (at night and during the day) we went to two dealers and spoke with on star four times. the repairs were supposed to be completed but each time the suv stalled on the interstate causing a possibly fatal incident for my family and other motorist. the 2007 tahoe that i have been sold is clearly dangerous and defective. now it's friday, june 9, 2006, and i have a brand new 2007 tahoe that is truly malfunctioning; my family needs safe and reliable transportation. *jb *nm

After only one month of purchase auto start feature does not work unless you were 3 feet away. the vehicle once sat over night would make a really loud clattering sound when you would turn on the engine. i took the car into the dealer and told them about the problems the dealer indicated that they had to reprogram the software in the tahoe to reprogram auto start. the next morning i was called and informed that they were unable to reproduce the clattering sound and that nothing wrong was detected with the vehicle so that it was ready for pick up. everything was o.k. for about a couple of months. auto start wasn't working again. at my third service visit to the dealer i noticed the tires were starting to get wasted towards the inside. the vehicle only had about 5,000 miles on it at the time. when the dealer was informed he indicated that the tires needed to be rotated. after about three tire rotations i noticed the tires getting warn out pretty badly on the inside. he indicated that the problem could be that it needs a front end allingnment only after the vehicle having less than 12,000 miles. the front end alignment was done on the vehicle.to this day that the tires are wasted more on the insides than the outsides.this last month we have had a problem again with the loud clattering sound in the engine when we start the vehicle.it has gotten alot worse i took it into the dealer and they said that they were aware of the problem and that it appears to be oil build up in the air compressor that when it sits for more thatn 3 hours it apparently makes this loud sound when you start the engine. he indicated that chevy is looking into the problem and to this day has not done anything about the problem.i was furious when they refused to do anything about a problem that chevy well knows is a manufacturer defect. *tr
