Selected complaints filed with NHTSA by 2009 Suzuki SX4 owners, lightly cleaned up (personal details are redacted by NHTSA).
I currently own a 2009 Suzuki SX4 crossover and was recently in a collision. I was going approximately 40 MPH in a forward direction when another vehicle crossed from one parking lot on the left side of the road trying to get into a parking lot directly across to my right. I applied the brakes before we collided, but still ended up colliding with the other vehicle in a t-bone position. I have front, passenger, and side skirt airbags in my vehicle and not one of the airbags deployed. The front engine compartment to my vehicle was completely smashed in and the other vehicle had extensive damage to the passenger side between the front and rear doors. Both my passenger and I were wearing seatbelts, so we were wiped forward and both had our heads collide with the headrests of our seats. We were both taken on backboards by ambulance to the local hospital. …
First issue is the airbags - driver side censor light has been on ever since I purchased the vehicle back in 2010. I had to get the engine replaced due to "rod knock" only to find that the used engine of 52,[redacted] miles has a leak on the rear main seal. It's likely that issue that lead to my original engine failing at around 74,000 miles. The driver airbag light is still on after said engine replacing. After reading the complaints on here, it's safe to say that I'll need to dish out over 1.1K to fix it. I had the recall for the passenger side airbag, had that fixed around the 74K mile mark. Got the car under 20K miles.
In November 2009, air bag error light came on and I took it to the dealership and the computer was reset. In December 2009, I was in an accident with a deer going 55 MPH head on and the air bags did not deploy, which was noted on the accident report. After receiving the vehicle back after repairs were made with OEM parts, the air bag error light came on again and I took it back to the dealer, who then reset the computer again. I am concerned.
I have not had an incident. My airbag light has been on for a long time. Took it in for recall & that did not fix the problem. They told me I had to bring it back in & pay $150 diagnostic fee to have them figure out problem with airbags. I haven't brought in. I'm frustrated they didn't fix it with the recall & feel it could be part of the recall issue & why should I have to pay for diagnostic tests & subsequent repairs.
While driving such car the airbag warning lights came on and state solid so I pull off the street to check what's going and shut off the car after that the car do not start immediately so take three times to started it. Since then the airbag warning lights stay on.
I have received two safety recall letters from Suzuki detailing a problem with my airbag system that matches a problem that I have had with the car for the last two years. My airbag light is always illuminated. When I received the first recall letter, I took my car to a Suzuki dealership. They confirmed the defect, but told me that the diagnostic code generated by their test did not match the one that Suzuki has said that they are covering. The issue is the same, and the fix is the same. The issue can be resolved by replacing a defective component in the seat cushion. This apparently requires that the entire seat be replaced at a cost of around $1000. I have called Suzuki several times in an attempt to get a resolution to this problem, but they refuse to cover the repair. …
My Suzuki sx-4 has shown an airbag warning light for just over two years. This began just shortly after the warranty period expired. I researched the problem online, and found that this is a common issue, and that most cases required a repair in excess of $1000. Recently, Suzuki issued a repair extension for the airbag system, but my situation conveniently does not qualify. Apparently, the diagnostic code is different from what Suzuki issued the extension for. I was told this morning by a Suzuki dealership that I must pay another $95 for diagnostics to find out what the diagnostic code means. This is not acceptable. I have tried talking to representatives at Suzuki's "customer relations" department, but to no avail. They insist that this issue is not covered under their repair extension, and that I must pay for additional testing, and repair in order to resolve this issue. …
The front passenger airbag warning light comes on intermittently. There is a known recall of the 2009 Suzuki SX4 for a problem with the sensor in the right front passenger seat. I bought this car as a used vehicle in December 2013. I have attempted to contact Suzuki motor of America directly by two separate letters to inquire about having the necessary repair made; also I have called three designated dealerships that handle Suzuki warranty repairs in orlando, tampa, and st. Petersburg, fl to inquire about the status of the recall. I have received no response from Suzuki motor of America, and the dealers know nothing about the status of this recall, other than verifying that my vehicle is one of those affected by the recall. …
Tl contact owns a 2009 Suzuki SX4. The contact stated that when anything was placed in the drivers side passenger seat, the air bag light illuminated which indicated that the air bag system has been deactivated. The dealer inspected the vehicle and determined that the battery failed. The battery was replaced and the computer system was reset. The contact has continuously experienced failures with the air bag system and has had the computer system reset multiple times. The manufacturer has not offered any resolutions for the failures. The dealer advised the contact that he should not place anything in the drivers side passenger seat. The contact stated that the failure could result in a crash and the air bags will not deploy. The failure mileage was 50 and the current mileage was 18,000.
Diver airbag light is always on. When taken for repairs code often differs. Authorized Suzuki dealership says that entire wiring system would need replaced for $3000, but could not guarantee that would fix it.. It can be cleared, but that is only effective for a few days. Light used to be intermittent, now it is constant. Authorized Suzuki dealership says when light is on, the air bag will not deploy. I've been forced to drive with this condition for 10K miles or more. My passenger seat had different airbag sensor problems. It has been replaced. Replacement of passenger seat did not affect driver side problem for better or worse.
