KIA Complaints

While driving in the carpool lane, the engine briefly cut-out and than a rattling sound was heard. We decided to immediately exist the free way at a left-side car pool exit as a precaution. Immediately after exiting, the car went into a complete stall. Had we remained on the freeway, we would have been stranded in the fastest lane with no shoulder and with traffic approaching from the rear at 70mph. Thus we likely avoided catastrophe. There was no warning light. The problems was later determined to be caused by a manufacturer defect resulting in a connecting rod bearing failure. Pursuant to a class action settlement the engine was replaced. I'm writing to let others know that this is a potentially life-threatening danger and that the knock sensor recall does not adequately address this. Also, the dealer mischaracterized the symptoms on the engine warranty invoice, misstating the narrative above, wrongly stating "customer states CEL started flashing when driving after light appeared vehicle would not accelerate properly or start." This quote is untrue. There was no warning, and the car stalled.

Since the first year of ownership, I have noticed that the vehicle burns oil excessively. I reported this issue to the Kia dealership, but I was told that “it is normal to add a quart of oil every other week.” Despite this statement, I believe this is not normal and points to a defective engine design consistent with the piston ring problems known in similar models and engines. In the summer of 2025, the vehicle began having hard-start issues when the engine is hot. Over time, I replaced several components at my own expense through an independent repair shop, including the alternator, starter, PCV valve, MAP sensor, and camshaft sensor. None of these repairs resolved the problem. When I returned to the dealership, they performed a borescope inspection and found scoring and damage on three cylinder walls inside the engine block. Thats whats causing the engine to seize when the engine is hot and make it hard to start and misfire when accelarate.

I'm writing to express my disappointment and frustration with my recent car purchase. The salesperson's failure to clearly explain the contract has left me with unexpected expenses and a higher payment than anticipated. Furthermore, the car's persistent malfunctions have caused me significant stress and anxiety. The manager told me he was not inclined to help me because he did not like my survey answers so he wouldn't help me like any other customer and I made sure he clarified this . The first day I had it at 40 miles I tried to take it back because I could not get the car to get out of traffic it would not go in any gear it just wouldn't Now, thr R flashes red, the backup camera stays on while driving forward for a while, zero rpms when your going 75, then so fast you can't see #s, window fluid comes right back in your face, something new all the time. Went hunting and had to back down a small hill and get a running start to make it. It's a brand new car. Should not be having problems. Despite my efforts to address these issues, the dealer's lack of cooperation, and Kia Customer Care, have only added to my distress. I just get passed from one person to the next. I ask to speak to a certain person and they won't let me or look into my notes. They told me they were kia property and i could not. This car is going to get me killed or badly hurt. I hope that you will take my complaints seriously and take immediate action to rectify this situation. Car will not go into gear after backing up go to put it in drive. Nothing. Stuck in traffic for 10 minutes. I took the car back to them within 36 hours the car had 40 miles on it I told them it was a brand new car and this should not be happening already and I asked if I could just get my truck back which I knew was dependable. They refused I took it back two more times they never asked to get it looked at they had a kid the first time get in my car with me and drive from one side of the building to the next so

Vehicle engine is using 1-2 quarts of oil every month or so. Vehicle only has 85k miles. Engine also has a rattle/tick when accelerating. I believe this is due to the excessive oil usage.

Dear Sir or Madam, My car was hit by another car when I tried to switch to the next lane. I did give a turning signal and observed before switching. However, a car sped past and hit my car. If the detection system had sounded an alarm at that time, I wouldn't have changed lanes at that moment. Unfortunately the Lane Assist and Blind Spot Detection System was not functioning correctly and failed to provide a warning. This malfunction didn't occur only once, it happened again after this accident(no consequences though).I gave feedback to Kia and I believe my detection system is not working consistently. I requested an inspection on my car. Kia refused to repair the damaged areas for inspection purposes, instead, they pushed OTA updates into my car, and they pushed twice within two weeks without informing me. I asked Kia if the existing issue still could be detected as they pushed the OTA updates. They didn't answer despite me asked twice. Feeling quite helpless, I searched and noted another person's Kia had the same issue: detection system not working consistently. I realized that I will be unable to prove that this vehicle had pre-existing issues due to the OTA updates. I'm worried that Kia might use this as an excuse to refuse to repair the damaged areas. I understand I cannot totally rely on the detection system, but this feature can enhance safety if it works well, at least I would pause and not act if it provides warning properly. Thank you.

The contact owns a 2024 Kia Telluride. The contact received notification of NHTSA Campaign Number: 25V494000 (STRUCTURE); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

I experienced a sudden engine failure on the highway due to the known Theta II engine defect. The engine completely shut down in the middle of traffic, nearly causing a serious accident. I never received any notice from Kia regarding the KSDS (Knock Sensor Detection System) update or any engine recall programs. When I contacted Kia Consumer Affairs, they told me they would not cover the engine replacement because the KSDS update was not installed prior to the failure. Kia admitted that the notice was sent to the previous owner, not to me, even though I am the current registered owner of the vehicle. I was never given the opportunity to install the software update or address the defect before this dangerous failure occurred. Kia representatives also stated that KSDS “was not a recall, only part of a class action lawsuit,” and therefore they are not obligated to cover the engine. This is misleading. The underlying Theta II engine defect was subject to NHTSA investigations and multiple recall campaigns. The sudden engine shutdown on a public highway created an immediate safety risk for me and other drivers. I am filing this complaint because Kia is denying coverage for a federally recognized engine defect due to their own failure to notify the current owner. I am requesting that NHTSA review Kia’s handling of this defect and their use of KSDS as a barrier to coverage. Their failure to notify current owners has resulted in dangerous, potentially life-threatening vehicle failures.

Forward collision system fully activated while driving eastbound in the fast lane on [XXX] . The sun was behind me. No glare. No cars or objects were in front of me or next to me. The dashboard started flashing and warning sounds activated and the car slammed on the brakes itself. The seatbelt locked up and left me bruised. Miraculously, the cars behind me avoided crashing into me while I accelerated out of it. I could have been killed. Dealership minimized my concerns. I don’t want to drive this car ever again unless someone can make sure it doesn’t happen again. This safety feature malfunctioning is a death trap.
