Selected complaints filed with NHTSA by 2007 Suzuki XL7 owners, lightly cleaned up (personal details are redacted by NHTSA).
I purchased my XL7 luxury new in 2007 with only 368+ miles. Before I had driven the vehicle for 3 months, the stability control and traction control lights came on and I was forced to take the vehicle for service. Before my vehicle warranty expired, I had to replace the gas caps numerous times resulting in the replacement of my catalytic converter. Now before my vehicle reached 100,000 miles, I am forced to replace the electrical harness (or complete computer output). Pugmire Lincoln Mercury is the only dealership in my area that provides repairs for my vehicle. After the harness repair, the check engine light is back on, and the codes (in less than 3 months) reveal that codes: [p2099, p0157, p2272 and p2099] resulting that there is an oil leak, an o2 sensor problem and another catalytic fuel problem again. …
The speedometer on the car doesn't work correctly if at all when driving as well as the the fuel gauge. The car started it's dingy noise as if the key is always in the ignition (when off) or a door is ajar. It won't shut off when driving or when turned and it drains the battery. This car has had more problems and should've been recalled. The fuel pump was recalled but there are so many issues that have happened. Driving without the speedometer working of the fuel gauge working correctly should be addressed and the dealer is not able to fix the problem. Super frustrating! Dealing with this issue now for over a year. Having to take it back to the dealership for the 3rd time.
Tl* the contact owns a 2007 Suzuki XL7. While driving approximately 25 MPH, the temperature gauge abnormally increased and the engine overheated. The contact maneuvered the vehicle to the side of the road and noticed smoke (no flames) under the hood. The vehicle was towed to an independent mechanic where it was diagnosed that the instrument cluster would need to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unavailable.
I went to turn left this evening departing off of a sharp turn and the car without warning became almost impossible to steer. Meanwhile, another automobile came flying around the turn and barely missed hitting me. It took much arm muscle but I was able to get the car home. This is our only family car and I am not comfortable any longer driving it. Prior to this incident the readings on the dash began acting up and the remote start quit.
Family was traveling to town when we smelled something that smelled like wires burning. Upon inspecting the vehicle, the smell disappeared. Upon leaving the stop sign we were at, we traveled about a quarter of a mile & the driver (myself), started to smell smoke. I then pulled over to further inspect the vehicle at which time, I turned on the overhead lamp in the vehicle since it was starting to get dark, & noticed that the whole front dashboard at this point, was glowing red, orange, & blue & thick black smoke was boiling up on the entire inside windshield & that the truck on the driver's side was fully engulfed in flames behind the dashboard. I immediately got my children (teenagers) out of the truck & leaned over to grab my purse & saw that there was blue flames dripping down from under the dashboard onto the floor where my feet had previously been just seconds before. …
Tl* the contact owns a 2007 Suzuki XL7. The contact stated that the steering wheel was making a strange noise and water was entering the vehicle on the passenger side floorboard. The contact stated that the water initially leaked from the sunroof which was taken to the dealer and repaired, but the problem persisted. From the leakage, mold began to form in the vehicle. It was taken to an authorized dealer who offered no assistance. The vehicle was also taken to a second dealer for the steering wheel failures where the contact was advised that the bushings would need to be replaced. The vehicle was not repaired, as the part needed for repairs was on backorder. The horn had also failed but the manufacturer was not notified of the failure. The VIN was unavailable and the current mileage was 48,082. The failure mileage was 35,000.
It is a shame this vehicle has not been recalled for any of the problems we have encountered. 1. Steering wheel is difficult to turn at slow speeds and makes loud rubbing noise. 2. Door locks will not unlock using key fob. Have to manually unlock by hand from the inside. I consider this a danger. 3. Vehicle will not maintain one speed on its own. Even with cruise control, the car's power decreases. I am petrified to pull out in traffic with this car. 4. Sunroof leaked all over into the interior electric due to improper installation from the factory. 5. Turn signal switch does not work. 6. Heating and cooling system does not work properly. Can only adjust temp if you set it on windshield defrost mode. 7. Rear end has strange bang coming from it. Dealer can't determine any problem.
Tl* the contact owns a 2007 Suzuki XL7. The contact stated that if there was a power failure while in the vehicle, he noticed that one would be unable to exit the vehicle. The unlock/lock button was electronically controlled. He had to have someone get a second key to unlock the doors so he could get out of the vehicle. The vehicle had not been inspected or repaired. The contact called the manufacturer who offered no assistance. The current and failure mileages were approximately 18,000.
Tl* the contact owns a 2007 Suzuki XL7. The contact started the ignition and all of the doors automatically locked and could not be unlocked. After three attempts, the doors were eventually unlocked by a person on the exterior of the vehicle using the key fob. The vehicle was not diagnosed for the malfunction. The contact had not notified the manufacturer of the one time occurrence. The approximate failure mileage was 15,000. Updated 12/20/11 updated 01/19/12
The engine overheated due to wiring shorting out on two fan motors. No fuse was tripped or light came on. Both motors shorted causing the connectors in the wiring harness to melt. Melting was discovered by local dealer. The wiring is being removed. I have pictures and I have documented the problem. The parts being kept due to seriousness of the defect.
