2006 Suzuki Grand Vitara Problems

What owners report

Complaints on this model year cluster around two things: the front passenger seat occupant sensor setting off the air bag warning light, and low-beam headlight bulbs that burn out or melt their sockets repeatedly. Steering-related complaints mostly involve the plastic power steering belt tensioner pulley. Many reports arrive well under 60,000 miles, and several owners say the air bag sensor problem returned after being replaced.

1. 1
   Air bags

   Air bag warning light from passenger seat sensor

   • 36 complaints (22%)
   • median 47,703 mi at 4.9 yrs old (29 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $2,000 (median of 14 quotes)
   • filed 2007–2017

   Owners describe the air bag warning light, and often the passenger seat belt light, staying on with no one in the seat or coming on whenever a passenger sits down. Dealers typically diagnose the occupant sensor mat built into the front passenger seat cushion and quote replacing the cushion assembly, with owners reporting quotes in the thousands of dollars. Some report the light returning after a prior repair or after the recall work, and a few describe the passenger air bag being disabled while the light is on. Widely spread from a few thousand miles to over 100,000, with many reports between roughly 30,000 and 70,000 miles.

   What to check: Turn the key on and confirm the air bag and passenger seat belt lights go out; sit in the passenger seat and watch for the light coming back on. Ask whether the sensor mat or seat cushion has been replaced, and whether recall 13V405000 was completed and when.

   2 excerpts from owner complaints in NHTSA records

   “We recently purchased a 2006 Suzuki Grand Vitara from an individual. On the way home the passenger seat belt off and air bag lights remained on. When we took it to a Suzuki dealer for diagnosis the results was the passenger seat sensor was not working therefore the passenger air bags were disabled. The service manager quoted $1800. To $2000. For replacement. We are very disappointed to find this to be a common problem with Suzuki.”

   NHTSA complaint #10426703, filed 2011-09, 66,500 miles

   “I have Grand Vitara 2006 with 21,500 miles. The airbag light turn on 21,000 miles. I check internet a lot of this SUV have the same problem. Airbag sensor under passenger seat is damage. Replace full seat $2,200 to $2,500.”

   Exterior lighting

   Low-beam headlight bulbs burning out or melting sockets

   • 29 complaints (18%)
   • median 54,000 mi at 4.5 yrs old (25 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2006–2022

   Owners report low-beam bulbs failing repeatedly, sometimes every few months and on both sides, with one report of both headlights going out at once. Several describe the plastic around the bulb connector or the socket itself as melted or burned, and a few note that bumps in the road seem to trigger failures. Dealers and mechanics sometimes replaced bulbs or sockets without resolving the recurrence, and some owners say they were told the headlights were working as designed. Reported from a few thousand miles up to well past 100,000, recurring across the life of the vehicle.

   What to check: Check both low beams and look at the bulb connectors and sockets for browning, melting or burned plastic. Ask how often the bulbs have been replaced and whether the sockets were ever changed.

   “Headlights constantly burn out. I have to change the low beams every couple of months and I am beyond tired of it. Suzuki knows that this is an issue, but refuses to issue a recall to fix it. I will never buy another Suzuki vehicle again. They aren't even selling them in the us, so I guess I won't have to worry about getting another one.”

   NHTSA complaint #10515040, filed 2013-06, 140,000 miles

   “The headlights, parking lights and brake lights burn out constantly. Major safety hazard. I have had to replace the headlights, parking lights and brake lights every 3-4 months for the 3 1/2 years we have this vehicle. Very careful with bulb handling and installation. Bulb connections appear to be burned and melted.”

   Steering

   Power steering assist loss from belt tensioner pulley

   • 20 complaints (12%)
   • median 54,012 mi at 4.5 yrs old (18 state mileage)
   • filed 2008–2015

   Owners describe sudden, heavy loss of power steering assist while driving, sometimes with pieces of a plastic pulley ring found in the underbody pan or a fractured pulley found afterward. The described part is the belt tensioner pulley for the power steering pump, whose plastic outer section owners say breaks up with heat and age. Some reports describe the belt slipping and steering becoming very difficult, and some note repairs done themselves or at an independent shop after a prior recall service. Mostly reported between about 30,000 and 95,000 miles, often during ordinary driving rather than at startup.

   Recall 10V250000Recall 18V667000

   What to check: Ask whether recalls 10V250000 and 18V667000 were performed and whether the pulley currently fitted is the updated metal type. Listen for belt squeal and check the pulley for cracks or missing outer ring material.

   2 excerpts from owner complaints in NHTSA records

   “Getting off the freeway I experienced a major loss of power steering on my 2006 Suzuki Grand Vitara. I was barely able to muscle it to my office a few blocks away. In searching the web, I discovered there is a design flaw with the belt tensioner where a molded plastic outer ring is prone to failure. When this breaks, the belt becomes loose and looses its grip on the power steering pump. Sure enough, parts of the broken outer ring were found in the pan under the engine. …”

   NHTSA complaint #10323631, filed 2010-04, 32,750 miles

   “I was driving my 2006 Suzuki Grand Vitara 2.7l SUV on a highway when the power steering belt tensioner pulley lost it's outer ring without warning. The loss of this ring caused the belt to slip, resulting in a complete loss of steering, not just power steering, but of steering altogether because the belt slippage was causing intermittent pumping of the power steering pump, causing fluid cavitation and making the wheel impossible to turn. By sheer luck I managed to get the car off of the highway without crashing. …”

   Vehicle speed control

   Unintended acceleration when shifting or at a stop

   • 9 complaints (6%)
   • median 55,000 mi at 5.2 yrs old (8 state mileage, few)
   • 9 mention a crash, fire or injury
   • filed 2009–2015

   Owners describe the engine revving and the vehicle surging forward unexpectedly, either after shifting into drive from a stop or while the brake was held at a light, in some cases ending in a collision with the vehicle ahead. In the reports, brakes were described as ineffective during the event, and owners say they found no matching recall when they looked. Reported between roughly 23,000 and 70,000 miles, typically from a stop or low speed.

   Recall 07V554000

   What to check: During a test drive, check that the throttle returns fully and the pedal does not bind, and that the shift lock holds the lever in park with the key out. Ask whether the throttle body or pedal assembly has been serviced.

   “My vehicle was at a standstill at a red light. I had the automatic transmission in neutral, with my right foot on the brake. While with my foot still on the brake, I shifted into drive and the car instantaneously sped forward at an uncontrollable high rate of speed causing me to hit the car in front of me.”

   “( corrected report ) my wife had just filled the truck up at sheetz..I went to pull it up and as soon as I put it in gear it took off...went about 70 feet into a parked car and brick wall..brakes were either ineffective or not working..my wife had a similar event the day before but it was brief and we did not pay attention to it.. Throttle was stuck wide open !! I was not injured and luckily was able to steer away from the steet right in fron of me!! …”

Buying note. Have a mechanic confirm the air bag sensor and recall status first, since that repair is the most commonly reported and the most expensive, then check the headlight sockets and the power steering pulley. Service records showing completed recalls and modest headlight bulb history are a good sign on this model year.
