2007 Chevrolet Trailblazer 360 Problems

What owners report

Owners of the 2007 Chevrolet TrailBlazer 360 most often describe headlights that cut out or fail to come on, often at night or on the highway. Fuel gauges that read empty or inaccurately, and power window and driver door switch faults, are also common, and several complaints say the fuel level sensor repair is only partly covered. Where mileage is given, all fuel gauge reports fall between about 34,000 and 56,000 miles, while headlight reports range from about 135 miles to about 185,000 miles.

   Headlights cutting out or failing while driving

   • 13 complaints (26%)
   • median 108,000 mi at 8.7 yrs old (11 state mileage)
   • filed 2007–2017

   Owners describe headlights going dark while driving, with low beams failing while high beams still work in some cases. Some say the lights flicker, come back on briefly, or cut out without warning, and in some cases the instrument panel also went dark. According to complaints, dealers replaced the headlamp drive module in some cases, while owners who tried relays, fuses or the switch box found no lasting fix. Mileage ranges from about 135 miles to about 185,000 miles, with most reports between about 66,000 and 120,000 miles, and many occur at night or on the highway.

   What to check: Ask whether the headlamp drive module has been replaced and whether a lighting recall was checked against the VIN, since some owners say the VIN was not covered. On a night test drive, check that the low and high beams both work and stay on, and ask the dealer to scan for lighting faults.

   “I was going down the highway and all of a sudden my headlights cut off. I turned the vehicle off and pulled some of the fuses and put them back in. The lights came back on later. We continued down the road to our destination and the lights went out again. We ended up having to get a hotel room for the night until we could drive home during the daylight hours.”

   NHTSA complaint #10722991, filed 2015-06, 185,000 miles

   “I was driving home one night about an hour after dark. As I was driving about 45 MPH, my headlights just completely went out without warning. After carefully pulling off to the side of the road I realized my high beams were still working. I looked into this issue and realized it was a relay 45 and 46 issue. The next day I replaced this relay and my lights worked. For a day. Now it's been almost a month, and I can't drive after dark. …”

   Electrical system

   Power window and door switch electrical faults

   • 8 complaints (16%)
   • median 80,672 mi at 6.8 yrs old (6 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2007–2015

   Owners describe driver door switches and power windows that stop working, with windows or locks failing and sometimes working again after a few minutes. Some report a driver window rolling down by itself, and a passenger window that failed while driving in cold weather. In some complaints the switch or door panel smoked, burned or caught fire, with a blown fuse, a melted plastic smell, or a burnt circuit board. According to complaints, the manufacturer first offered to share part of a repair cost and later declined to pay. Where mileage is given, most reports fall between about 58,000 and 90,000 miles, and some occur while the car is stopped, parked or driven in cold weather.

   What to check: Ask whether the driver door switch and window modules have been inspected for burnt or melted parts, and test each window and lock from both the switch and the door. Ask for service records covering any smoke, burning smell or fire in the door area.

   “I was trying to roll down the windows for my wife. The windows would not roll down at first. I checked to make sure that the window was not lock and it wasn't. After a few minutes the window finally rolled. Down. This has happened on several occasions.”

   Fuel system

   Fuel gauge reading empty or inaccurate

   • 6 complaints (12%)
   • median 47,500 mi at 4.5 yrs old (5 state mileage, few)
   • filed 2011–2016

   Owners describe fuel gauges that read empty or inaccurate, sometimes shortly after the tank was filled, and some report the check engine or low fuel light coming on. In some complaints the reading starts out intermittent and then becomes constant, and some owners track miles per tank to watch for running out. According to complaints, the fuel level sensor or fuel pump module was replaced in some cases, sometimes at a cost to the owner, and the manufacturer offered only partial cost sharing. Some say the manufacturer describes the sensor as a wear item and has not issued a recall for it, and that running out of fuel is a concern. Where mileage is given, all reports fall between about 34,000 and 56,000 miles, and the gauge problem often starts as intermittent before becoming constant.

   What to check: Ask whether the fuel level sensor or fuel pump module has been replaced, and whether any fuel gauge or check engine codes were recorded. Compare the gauge reading with actual fuel use over a few fill-ups, and ask whether any cost-sharing offer applies to this VIN.

   “Fuel gauge started malfunctioning sporadically. Would drop to empty for a while then come back up after driving a distance. Now gauge is always on empty and cel always on with code p0463.(fuel level sensor circuit high voltage) this seems to be a known problem with this GM platform. I am keeping track of miles per tank and refilling at 200 miles but the cel worries me because I don't know if there may be another, more serious, issue with the vehicle.”

   “I am a disabled 62 years old lady and I have a trailblazer 2007. About 2 month the gasoline gauge was showing empty all the time, I took the car to the dealer and they told me that they know there is a problem with the gauge but GM only going to pay a portion of the repair. I have to pay 139.00 of my pocket. I ask the reason it is a recall. One the attendant said the if recognize that was a recall they have the reputation of the trailblazer was going to be damage. …”

   Air bags

   Airbag deployment and warning light problems

   • 5 complaints (10%)
   • median 8,200 mi at 1.0 yrs old (5 state mileage, few)
   • 3 mention a crash, fire or injury
   • filed 2007–2011

   Owners describe airbags that did not deploy in collisions, in some cases where the vehicle was totaled or the front end was crushed. Some describe the passenger airbag warning light showing the airbag as off with a passenger seated, with the light blinking, and say dealer diagnostic visits did not find the problem. Some report side curtain airbags deploying after the front tire rolled up a curb with no impact, and the replacement cost was high. According to complaints, the manufacturer said a crash of that type would not have triggered deployment. Where mileage is given, most reports are at about 1,000 to 17,000 miles, though some are at about 118,000 miles, and the crashes described happened at about 35 to 45 mph.

   What to check: Ask whether the airbag system has been scanned for stored codes, and check that the passenger airbag status light behaves correctly with and without a passenger. Ask for records of any airbag replacement or crash repair for this VIN.

   “Traveling on a city street at about 40 MPH and the trailblazer got too close to the curb. The front tire rolled up on the 3-4 inch curb and back onto the street. The side curtain air bags deployed. There was no impact to the SUV. The curb was not that high and it was not a sufficient motion to create a side shock to cause the airbag to deploy. The airbags were replaced at a cost of over $3,000. My insurance company paid the claim and I paid a $1,000 deductible and got an accident premium on my insurance policy. …”

   NHTSA complaint #10226734, filed 2008-05, 7,000 miles

   “A vehicle pulled directly across my path while I was traveling approximately 45 MPH, resulting in a t-bone collision. My vehicle was totaled. Somehow, my airbags did not deploy.”

   Brakes

   Brake rotor warping, corrosion and braking problems

   • 7 complaints (14%)
   • median 15,350 mi at 1.2 yrs old (4 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2007–2011

   Owners describe brake rotors warping and corroding early in ownership, with a dealer machining the rotors after a few thousand miles. Other owners report rust on a rear brake line bracket, brakes that squeal and drag when stopping, and a report of the brakes not stopping the car at low speed, followed by a rear-end collision. According to complaints, the dealer attributed the braking failure to other components, while the manufacturer could not duplicate it. Where mileage is given, reports are at about 3,700 to 27,000 miles, and the rotor warping was described early in ownership.

   What to check: Ask whether the brake rotors have been machined or replaced, and check the rotors for warping or rust and the rear brake line bracket for corrosion. On a low-speed test drive, check that the brake pedal stops the car normally and that there is no squeal or drag when stopping.

   “2007 chevy trailblazer with multiple issues. Customer states that her vehicle has brake problems, front end vibration problems, tire wear, and excessive fuel consumption. The brakes made a squealing and dragging noise when coming to a stop. It would take several attempts to close the liftgate, the engine would misfire/stall while in idle, there was a smell of oil burning, the vehicle was slow to gain speed, there was extreme noise coming from all of the doors and windows. The settings for the side mirrors did not keep their memory. …”

Buying note. Buyers considering this model year should check the headlight, fuel gauge and door switch repair history, and ask whether any recall or cost-sharing offer applies to the specific VIN. Complaints describe repeated headlight and gauge repairs that did not stay fixed, so a documented repair record and a night test drive are worth asking for before purchase.

Summary written with AI from a sample of 48 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records.
