2008 Kia Sportage Problems

What owners report

Complaints from owners of this model year center on the ABS hydraulic unit (HECU): warning lights for ABS, ESC and brake come on, brake fluid leaks onto the module, and some vehicles were parked or driving when smoke or fire appeared from that area of the engine bay. A second recurring theme is rough or delayed automatic transmission shifting, often reported at low mileage. The rest of the sample covers stalling and engine control problems, body corrosion, and interior electrical faults, mostly at higher mileage.

1. 1
   Brakes

   ABS/ESC/brake warning lights and hydraulic unit failure

   • 23 complaints (23%)
   • median 90,000 mi at 8.2 yrs old (21 state mileage)
   • 7 mention a crash, fire or injury
   • owner-quoted repair $2,311 (median of 7 quotes)
   • filed 2010–2024

   Owners describe the ABS, ESC, brake and sometimes traction-control lamps lighting together and staying on, with the ABS/ESC dash button having no effect. Several were told by dealers or shops that the hydraulic module (HECU) assembly needed replacement, with quotes commonly cited in the $2,000-$3,000 range, and some said the repair was not covered by warranty or a recall. A few complaints mention the brake pedal going to the floor, brakes locking up, or fluid leaking from the unit onto its circuit board. Reported from roughly 30,000 to 150,000 miles, with many cases in the 45,000-90,000 mile range.

   Recall 22V800000Recall 16V815000

   What to check: Ask whether the HECU has been replaced or inspected, and whether recalls 16V815 and 22V800 were completed. Check that all dash warning lamps go out after start-up and look for fluid residue or corrosion around the ABS module on the passenger side of the engine bay.

   “While driving at a continuous speed of 55mph on the main road, the ESC light randomly came on and the car jolted into 1st gear. I was unable to move it and it was towed back to my house. Since then, the brake pedal goes to the floor without stopping the vehicle.”

   NHTSA complaint #11322464, filed 2020-04, 175,000 miles

   “Due to dashboard lights of ABS, ESC, traction control, ... I was told the hydraulic assembly needs to be replaced, est cost of ... Abs pump and module and that it would cost me $2700 to fix.”

   Electrical system

   Smoke or fire from the engine bay ABS/wiring area

   • 18 complaints (18%)
   • median 112,000 mi at 8.1 yrs old (15 state mileage)
   • 14 mention a crash, fire or injury
   • filed 2011–2023

   A number of owners report smoke, a loud pop, or open flames from the area of the ABS module and wiring harness near the right front wheel well, in some cases while the vehicle was parked and not running. Complaints describe melted plastics, blistered paint and scorched wiring, and several mention that a fire department put the fire out. Some owners say they learned of recall 16V815 only after an incident, and others say the firing was linked to a slowly draining battery and an illuminated ABS lamp beforehand. Spread across the sample from about 50,000 to 150,000 miles, frequently while the vehicle was parked.

   Recall 16V815000Recall 22V800000

   What to check: Confirm both the wire harness cover recall (16V815) and the later HECU fire recall (22V800) were completed. Inspect the harness connector and module area for water intrusion, corrosion or a poorly sealed cover.

   “I recently purchased a 2008 Kia Sportage at an auction. It has sustained an engine compartment fire that appears to have been caused by the wiring harness and / or ABS pump. This is the lx model with 2.7 v6 automatic 4wd. I just saw another Sportage 2010 model that had a fire in the same ABS pump area at an auction. Thought you might be interested as there seems to be a problem ..”

   NHTSA complaint #10386375, filed 2011-03, 27,600 miles

   “I was in the car, parked in a wendys parking lot, engine off, radio on. There was a loud pop followed by smoke, a gentleman in a truck 3 spaces away heard it and saw it. We got out to look at it and the smoke was increasing, I opened the hood and you could see flames about 2 inches high around the box mounted inside the engine compartment, on the passenger side up near the headlights and over the wheel well. …”

   Transmission and drivetrain

   Rough or delayed automatic transmission shifting

   • 12 complaints (12%)
   • median 30,819 mi at 8.4 yrs old (11 state mileage)
   • filed 2008–2023

   Owners describe the automatic transmission hesitating, slipping, or shifting sharply between gears, sometimes with the engine revving up between shifts or the car jolting into a lower gear. Complaints mention dealers reprogramming the control module or resetting the vehicle, and in some cases replacing the transmission under warranty, with the symptom returning afterwards. Some reports link the shifting behavior to warning lamps and transmission codes appearing at the same time. Often at low mileage, from under 20,000 up to about 90,000 miles, at speeds around 25-55 mph.

   3 related service bulletins

   What to check: Test drive from a cold start and note any hesitation or harshness on the 2-3 shift. Ask whether the transmission control module was ever reprogrammed and whether the correct fluid was used at the last service.

   “I am an owner of a Kia 2008 Sportage with approximately 12,000 miles. About 9 months ago, the engine and brake lights went on. It was evident that car had a transmission problem, you can hear the engine knocking when you would go park to drive or reverse to drive etc... The dealership said I needed a new transmission and all new brakes. They couldn't explain why the transmission was faulty on a car that had at the time less than 11,000 miles. …”

   NHTSA complaint #10621705, filed 2014-08, 10,000 miles

   “While driving rpms would jump. Had vehicle inspected and was told I would need to replace the transmission or get it rebuilt. Replaced the transmission but didn't seem to resolve the issue. Rpm's still jump while driving. Almost as if I'm pushing the gas down hard then letting off. Not sure what the issue may be, ive been told it could be the cruise control or possibly shift solenoid. Vehicle stalls/jumps while in motion, happens on interstate as well as city streets and back roads. …”

   Engine

   Engine stalling and sudden loss of power

   • 17 complaints (17%)
   • median 89,000 mi at 8.8 yrs old (16 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2008–2024

   Complaints describe the engine stalling or cutting out while driving, sometimes repeatedly, with the check engine lamp on. Owners report dealers replacing the mass airflow sensor or its connector, replacing the electronic control unit, or being unable to reproduce the fault. A few describe rough running, an abnormal burning smell, or unintended acceleration with cruise control engaged. Broad range, from roughly 10,000 to 145,000 miles, at ordinary road speeds.

   2 related service bulletins

   What to check: Ask for any history of stalling diagnostics, mass airflow sensor or ECU replacement, and check for stored engine codes. A scan tool reading of pending codes before purchase is worthwhile.

   “I was driving the vehicle when it stalled, restarted than stalled again. Had it towed to the dealer who replaced the mass air flow sensor. On 6/25/14 the same happened again (intermit, runs rough then stalls out. This time the dealer found a pin on mass air flow connector was bad and the replaced clip assembly. Today, 06/28/2014 the vehicle stalled out and I had it towed to the dealer who loaned me one of their vehicles because I had to leave my vehicle.”

   NHTSA complaint #10606687, filed 2014-06, 57,472 miles

   “The Kia Sportage 2008, has the modules misfire and the Kia Sportage completely turns itself off while in drive at 45 miles per hour. This happened to me on five different occasions randomly, and the Kia depot in santa ana, said that they could not find the problem on the vehicle, and decided not to keep the vehicle longer to find out what was causing this problem that could be a fatal hazard for anyone that would be driving this vehicle. I was almost hit by other cars while driving this vehicle. …”

   Body and structure

   Underbody and subframe corrosion; hood latch corrosion

   • 10 complaints (10%)
   • median 128,500 mi at 11.4 yrs old (6 state mileage, few)
   • 4 mention a crash, fire or injury
   • filed 2008–2023

   Owners describe rust on the underbody, subframe and oil pan, and in one case a hood latch that was corroded and would not hold, letting the hood fall. Complaints mention that a dealer or manufacturer was contacted but the vehicle was not repaired, and some note the corrosion was found while the car was being inspected or serviced. Mostly at higher mileage, from about 64,000 to 155,000 miles, on older vehicles.

   7 related service bulletins

   What to check: Look under the rear floor and subframe for bubbling or flaking rust, and ask whether the anti-corrosion service campaign (SC104) was applied. Check that the hood latches securely and releases smoothly.

   NHTSA complaint #10957811, filed 2017-03, 64,000 miles

   “The contact owns a 2008 Kia Sportage. The contact stated while inspecting under the vehicle, he noticed the subframe was corroded. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer had been informed of the failure. The failure mileage was approximately 155,000.”

   NHTSA complaint #11437533, filed 2021-10, 155,000 miles

Buying note. This model year has a recurring ABS hydraulic-unit theme that shows up both as warning lights and as underhood fires, so verifying that both ABS-related recalls were completed and that the module area is dry and uncorroded matters more than cosmetics. A pre-purchase inspection that includes the brakes, transmission behavior on a cold test drive, and the underbody for rust is the practical way to judge a specific example.
