My car broke down in december 2015, when I took it to the Kia service department and they fix it. I paid over 1000 usd. 2 months later there was a safety recall for the same reason my car broke down couple monts before that recall. Until this day I have tried to get my money back and they dont want to give me a refund even though it was a factory defect. I was driving on the freeway when the car…

What stands out
Among the 13 model years of Kia Forte in our records for powertrain problems, this one ranks #3 by owner-complaint volume.
No new NHTSA powertrain complaint has been filed on this vehicle in over 8 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2011 Kia Forte powertrain shows a pattern of serious failures including random stalling, transmission inability to engage gears, and catastrophic engine seizure—many occurring before 100,000 miles and persisting even after dealer repairs. Avoid this vehicle unless you can verify a complete powertrain replacement with documentation.
Owners report the 2011 Forte powertrain as dangerously unreliable. The most serious failures include random engine stalls while driving at highway speeds and in stop-and-go traffic—sometimes requiring repeated dealership visits that don't fix the problem. One owner's engine seized completely with metal flakes throughout the oil and transmission, requiring full engine replacement.
Transmission issues dominate these complaints: vehicles refuse to engage gear at all (one owner reports 70% failure rate at under 70,000 miles), drop unexpectedly into lower gears during acceleration with no diagnostic codes showing up, and lose all drive while at highway speeds. Some transmissions have been replaced only to jerk violently when accelerating or stopping afterward. One owner paid over $1,000 for a transmission hose repair in December 2015, then received a recall notice two months later for the same defect and was refused reimbursement.
Engine problems span sensor faults (crankshaft position, MAP sensor, throttle actuator control), rough idle, no-start conditions, and tapping noises. One owner faced mounting fault codes at 106,890 miles despite replacing plugs, coils, and sensors. An unconfirmed report of unintended acceleration resulting in a crash is also noted. Dealerships often cannot diagnose these issues, and some refuse warranty coverage claiming uncertainty about root cause.

Failure modes owners describe
Random engine stalling while driving
Engine stalls unpredictably during normal driving, including highway traffic and low-speed situations (crossing railroad tracks, city driving). Motor revs when accelerator is pressed but vehicle does not move. Restart required to resume operation. Multiple instances reported in same vehicle with repeated dealership service attempts unsuccessful.
When: 2016; occurring sporadically across multiple driving situations; one case reported two weeks after dealership service
Symptoms owners cite: Engine stalls suddenly while driving; No response when accelerator pressed despite engine revving; Loss of power while in motion; Multiple recurrences in same vehicle
Repairs/costs cited: Repeatedly brought to KIA dealership; escalated services performed three separate times; problem persisted after each repair
Recalls/TSBs owners mention: KIA corporate consumer assistance requested escalated service visits at dealership three times; issue unresolved
Engine seizure with metal debris
Engine suddenly seizes mid-drive with loud metal crunching/snapping noise. Check engine light illuminates before failure. Black fluid (later identified as oil with metal flakes) leaks from engine. Oil was 2.5 quarts low at previous service. Auto repair shop noted scraping noise and mentioned cam-related concern but deemed non-urgent. Engine stops completely without coasting; vehicle jumps upon stoppage. Metal flakes found in oil, transmission fluid, and other engine compartments.
When: Approximately 4 days after oil change; oil reservoir was full at departure; vehicle had roughly 20 mph when seized
Symptoms owners cite: Metal scraping/crunching noise before complete failure; Check engine light illumination; Sudden complete engine stoppage; Black fluid leaking from engine; Metal flakes in oil and transmission fluid
Repairs/costs cited: Engine replacement required at minimum; short block being sourced as replacement; extensive metal contamination found throughout engine and transmission
Transmission failure to engage gear
Vehicle refuses to shift into gear or stalls immediately after cold start, with problem becoming more frequent over time. At less than 70,000 miles, occurs 70% of the time. Safety hazard as transmission could engage any gear unexpectedly while driving at highway speeds.
When: Problem escalates from occasional issue after initial start to persistent occurrence at 70,000 miles
Symptoms owners cite: Car dies shortly after initial starting; Transmission will not engage gear; Problem worsens over time; Unpredictable gear engagement while driving
Repairs/costs cited: KIA initially placed under specific claim number for warranty coverage; later refused repair citing uncertainty of cause and expired factory warranty
Recalls/TSBs owners mention: Initial claim number issued for warranty consideration; later refused service, claiming extended warranty does not cover powertrain/shifter components
Unintended downshift and stalling at idle/low speed
Transmission downshifts unexpectedly during normal acceleration, feeling like sudden brake engagement for approximately one second before recovering. Vehicle stalls at red lights and at low speeds (5 mph), causing immediate loss of power steering. No diagnostic trouble codes appear despite multiple failures. Occurs during acceleration when expecting normal upshifts (e.g., 4-5-6 sequence instead drops to 3rd). Cruise control inoperates during events.
When: Occurs at red lights and low-speed driving; also during acceleration phases
Symptoms owners cite: Unexpected transmission downshift during acceleration; Stalling at red lights; Stalling at low speeds (5 mph); Loss of power steering during stall; Cruise control becomes inoperative; No diagnostic codes present
Repairs/costs cited: Taken to KIA; KIA referred to AAMCO transmission shop; AAMCO reset transmission values with no effect
Recalls/TSBs owners mention: KIA referral to independent transmission specialist (AAMCO)
Engine misfire, sensor failures, and no-start condition
Engine develops tapping noise followed by power loss during acceleration and hill climbing. Crankshaft position sensor fault diagnosed and replaced. Later develops rough idle with MAP sensor code and cylinder 2 misfire. After plug, coil, and MAP sensor replacement, engine will not start with no spark. Diagnostic codes indicate persistent MAP sensor fault, cylinder 2 misfire, throttle actuator control sensor fault, and powertrain control module fault. Owner reports similar issues in other owners' 2.0-liter engines and notes other models with same engine have been recalled.
When: At 106,890 miles; initial tapping noise and power loss, escalates to no-start condition
Symptoms owners cite: Engine tapping noise; Loss of power during acceleration and uphill; Rough idle; No-start condition; No spark at plugs
Codes mentioned: Crankshaft position sensor, MAP sensor, Cylinder 2 misfire, Throttle actuator control sensor, Powertrain control module
Repairs/costs cited: Crankshaft position sensor replaced; spark plugs, ignition coils, and MAP sensor replaced; engine remains non-functional
Gear shifter stuck in reverse
After starting vehicle and reversing, gear shifter becomes mechanically stuck in reverse gear with no warning light. Independent mechanic manually shifted linkages into park, suggesting possible linkage damage. Vehicle not officially diagnosed or repaired.
When: At approximately 200,630 miles during reverse operation
Symptoms owners cite: Gear shifter stuck in reverse; No warning lights illuminated
Repairs/costs cited: Independent mechanic manually adjusted shifter linkages into park; suspected linkage damage noted but not confirmed or repaired
Recalls/TSBs owners mention: Unknown dealer advised customer to bring vehicle for diagnostic; no repair performed
Transmission fluid hose rupture
Vehicle stops completely on freeway due to transmission fluid hose failure. Owner paid over $1,000 to KIA service department for repairs in December 2015. Two months later, a safety recall was issued for the same failure. KIA has refused to refund the repair cost despite acknowledging factory defect.
When: December 2015; recall issued 2 months after repair
Symptoms owners cite: Complete vehicle stoppage on freeway; Transmission fluid loss
Repairs/costs cited: Transmission hose repair/replacement performed at KIA dealership for over $1,000
Recalls/TSBs owners mention: Safety recall issued for transmission hose issue 2 months after owner's repair; KIA refuses refund despite factory defect acknowledgment
Transmission loss of drive with jerking after replacement
Vehicle suddenly loses power and drops from 60 mph to 40 mph on highway. Complete transmission replacement performed at dealership. After return, vehicle jerks and stalls during acceleration. Dealership performed transmission 'relearn' procedure which failed to resolve issue and made it worse. Vehicle now jerks when stopping, accelerating, and when shifting out of park at speeds of 5 mph or higher.
When: Occurred at 60 mph highway driving; problems persist after transmission replacement and relearn
Symptoms owners cite: Sudden power loss and unintended downshift on highway; Jerking during acceleration after repair; Stalling after repair; Jerking when stopping; Jerking when accelerating at 5+ mph; Jerking when shifting out of park
Repairs/costs cited: Complete transmission replacement performed at dealership; transmission relearn procedure performed with no improvement
Loss of acceleration with anti-skid warning
Anti-skid warning indicator illuminates while driving at various speeds. Vehicle will not accelerate when pedal is depressed. Dealership unable to diagnose failure despite inspection.
When: At approximately 96,000 miles
Symptoms owners cite: Anti-skid warning light illuminates; No acceleration response when pedal depressed
Recalls/TSBs owners mention: Manufacturer notified; vehicle not repaired
Power loss and no reverse capability
Vehicle loses all power while driving at 35-45 mph with no warning lights. Will not accelerate or reverse. No diagnostic codes generated.
When: At 24,000 miles
Symptoms owners cite: Complete loss of power; Unable to accelerate; Unable to reverse; No warning lights
Repairs/costs cited: Vehicle towed for diagnostic; not repaired
Rough transmission shift with warning light and odor
Engine warning light illuminates during driving. Vehicle shifts into gear roughly with abnormal odor present. Dealer diagnosis indicates transmission replacement needed but vehicle not repaired.
When: At 56,220 miles
Symptoms owners cite: Engine warning light illumination; Rough gear shifting; Abnormal odor from vehicle
Repairs/costs cited: Dealer diagnosed transmission replacement needed; not performed
Unintended acceleration with brake failure
Vehicle accelerates on its own without driver input. Brakes fail to stop vehicle despite hard pedal application with both feet. Vehicle collides with wall at significant speed, impact disconnects power and stops vehicle after approximately 50 feet.
When: July 24 (year not specified); vehicle was being driven on side street by 21-year-old
Symptoms owners cite: Unintended acceleration; Brake failure/no braking response; Vehicle continues accelerating despite maximum brake application
Sudden jerk and complete loss of drive
While driving at normal highway speeds, vehicle experiences sudden violent jerk (as if hit from behind). Vehicle completely loses ability to move. Placing transmission in park and back to drive does not restore drive. Manual shift mode also non-responsive.
When: During normal highway speed driving
Symptoms owners cite: Sudden violent jerk; Complete loss of drive; Transmission unresponsive after restart attempt; Manual shift mode non-responsive
Transmission failure to shift during highway merge
While attempting to accelerate to merge onto interstate highway, transmission will not change gears. Vehicle disabled on roadside.
