We have had severe headlight issues with this 2006 Suzuki Grand Vitara since we purchased it. The wiring harness for the headlights continue to melt even after being replaced 3 times! the dealership or Suzuki motors have been of any help and offer zero assistance with the problem. A quick search online of Grand Vitara headlight issues will get thousands of results. I am confident that Suzuki is well aware of this issue, but simply refuses to issue a recall notice because it will cost them many millions of dollars in repairs. My headlight caught fire driving down the interstate and I could have been killed due to their faulty equipment. This is a problem that a gov't agency needs to make Suzuki fix. This could cause accidents and could be fatal if headlights are bursting in to flames. I suggest anyone who has headlight harness sockets that are melting. . . Not drive the vehicle! it can and will catch on fire!!!.
At apx. 10000 miles, the air bag light came on with the car, and did not go out. Took the vehicle to the dealer; was informed that the driver's side air bag weight sensor had failed in the seat, and would be replaced under warranty. At apx. 25000 miles, the air bag light again came on. The car was now out of warranty. I took the car to the dealer, and was informed that the air bag weight sensor in the seat had failed, and needed to be replaced. When I informed the service manager that this was the second time that this had happened, they offered to replace the sensor for $300 dollars. Which I paid for. At apx. 52000 miles, the air bag light came on again. (it was intermittent, as it would sometimes not be on) after a few months, we were involved in a minor accident, (struck by another car on rear quarter) when the car was repaired, I was asked about the seatbelt light; I was informed that the diagnostic code indicated a failure of the weight sensor. I informed the repair shop and insurance that the light was not due to the accident. While I was at the shop, the error light went out, but subsequently (within 5 miles) came back on again. The shop informed me that the problem was <<<probably>>> in the wiring harness or sensor connector, rather than the actual sensor (as the problem was intermittent. ) the car has not been fixed, and the air bag light is still on. That is three air bag weight sensor related problems with the same car. This is a safety issue, and it seems to be a pervasive safety issue with the 2006 Grand Vitara. . . [in addition, the car blows the low-beam (and sometimes high beam) headlights quite often - more than any other car I've driven in nearly 40 years of driving. ].
