Recalls
4 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Electrical Vehicle recall #00V259001 · 2000 · 165,977 vehicles
What's wrong: 5 liter v-6 engines and all elantra model vehicles May have experienced intermittent low-speed engine stalling, which could occur if the maf (mass air flow) sensor electrical signal is interrupted as a result of engine vibration transmitted to the maf sensor connector wiring harness.
Why it matters: This condition can cause the engine to stall, increasing the risk of a crash.
The fix: Dealers will re-route the maf sensor connector wiring harness.
Airbags Vehicle recall #01V347000 · 2001 · 86,513 vehicles
What's wrong: The supplemental restraint system (SRS) air bag warning light could illuminate due to motion of the side impact air bag wiring harness and side impact air bag wiring harness connector that mount to the adjustable seat cushion assembly. This condition only relates to the driver and/or passenger seat-mounted side impact air bag(s).
Why it matters: This condition could prevent seat mounted side impact air bag deployment during an accident where such deployment should occur. Non-deployment of the SRS side impact air bags could increase the risk of injury during an accident where side impact air bag deployment is intended.
The fix: Dealers will more securely fasten the front seat side impact air bag wiring harness and connectors to the vehicle's front seat cushion frames. Owner notification will occur in six mailings on May 27, June 3, June 10, June 17, June 24, and July 1, 2002.
Airbags Vehicle recall #02V105000 · 2002 · 145,355 vehicles
What's wrong: On certain passenger vehicles, an intermittent condition that leads to the supplemental restraint system (SRS) air bag warning light illumination could result from motion of the side impact air bag wiring harness and side impact air bag wiring harness connector which mount to the adjustable seat cushion assembly. This condition only relates to the side impact air bags and could prevent air bag deployment during a…
Why it matters: Non-deployment of the SRS side impact air bag could increase the risk of injury during a side impact crash.
The fix: Dealers will more securely fasten the side impact air bag wiring harnesses and connectors to the vehicle's front seat cushion frames. Owner notification began May 28, 2002.
Suspension Vehicle recall #09V124000 · 2009 · 188,282 vehicles
What's wrong: Road salt applied in these jurisdictions during the winter months May result in progressive, internal corrosion of the front sub-frame on the vehicles, and May result in thinning or perforation of the sub-frame steel. The corrosion is frequently visible and often discovered during inspection or routine maintenance, and owners May also hear noises or notice tire misalignment and steering pull. If these signals are…
Why it matters: If that happens, the vehicle May lose drive power to the wheels, and the front wheel May make contact with the fender or wheel well, thereby increasing the risk of a crash.
The fix: Dealers will measure the thickness of the front sub-frame and inspect the front sub-frame for corrosion damage and, if necessary, the front sub-frame will be replaced with a new sub-frame that incorporates additional holes in the upper and lower panels. If the front sub-frame does not require…
