Kia Forte won't shift problems

Filed Oct 8, 2026 · Driver assistance, Engine · VA

During a day trip on 9/19/26 my 2020 Kia Forte (purchased new and well maintained) lost power and several of the dash board lights came on including check engine, traction/stability control, and collision alerts. The car entered what I was told is "limp mode". I had the car towed home and after one shop misdiagnosed the problem I had it towed to the Kia dealership where purchased. I was told the engine had code p0017. I was sent a document that the "phaser sheared off p0017 exhaust cam and cvvd gear timing off-recommend long block-cvvd replacement may still have engine damaged after replacement" with a price of $9053.39 attached. Kia service manager is supposed to be seeing about assistance for repair as it is cost prohibitive and I have proof of proper maintenance however I am not receiving info on process unless I reach out. Car has been in Kia possession since 9/24/26.

Four times, my 2023 Kia forte has went into limp mode. Three times accelerating onto the freeway, the blindspot/anticollision (BCA) system reset. This put the vehicle in limp mode and it deaccelerated to 3 mph. I had to pull over and restart the car. The other time, I was turning right at an intersection. After the light turned green, the system reset again. I had the AGM battery replaced after the second time, but the BCA system continued to reset and the car went into limp mode. This is dangerous during driving, especially if there is no where to pull over. The car won't go more than three mph.

respectfully submit this correspondence to request formal assistance regarding my 2015 Kia Forte EX, a vehicle covered under the class settlement. The vehicle is exhibiting severe symptoms consistent with KSDS‑related engine failure, yet the required diagnostic protocol has not been completed by the servicing dealership. The KSDS software update was performed in May 2022, and the vehicle currently has only 92,000 miles on the odometer, placing it well within the settlement’s mileage parameters. Despite this, the dealership has failed to follow KSDS procedures and has not produced any written documentation of its findings. All communication with the dealership has occurred exclusively by telephone. Despite repeated attempts to obtain information, I have not received a diagnostic sheet, video recording, code report, KSDS documentation, or any written summary of the vehicle’s condition. All statements provided to me have been verbal and inconsistent. My **primary symptoms** include: - Persistent and worsening **engine ticking** - **Burning excessive amounts of oil** - Activation of **limp mode** - A **flashing check engine light** These symptoms align with known indicators of KSDS‑related engine failure and warrant immediate and proper diagnostic evaluation under the settlement terms. The dealership has verbally stated that the issue may be related to **spark plugs and ignition coils**. However, plugs and coils are a **well‑documented secondary symptom** of rod bearing failure, caused by oil contamination and misfires resulting from internal engine damage. This further supports the likelihood of KSDS‑related engine failure. Kia corporate has not referenced documentation of any kind. They have not requested it, indicated they are awaiting it, or provided guidance regarding its submission. Instead, corporate has repeatedly stated that they “must defer to the dealership,” despite the dealership’s failure to perform or submit the required KSDS diagnostic materials.

Vehicle: 2012 Kia Forte Recall: the federal safety agency 23V‑652 (Kia SC284) – HECU/ABS fuse recall My vehicle underwent this safety recall in 2025. The dealership replaced the HECU fuse. Immediately upon leaving the dealership after the recall repair, the same warning lights returned. I contacted the dealership immediately before fully leaving the area to report the issue. I also contacted Kia Corporate after the warning condition returned. Kia was aware the warning lights returned immediately after recall completion. I was advised if the vehicle later entered limp mode again, to contact Kia roadside assistance for towing support per prior guidance. The warning condition was not resolved by the recall repair. The brake warning light remained present, additional warning indicators later appeared, and the vehicle ultimately entered limp mode in January 2026, resulting in loss of reliable transportation and safety concerns. Due to this condition, I was forced to rely on a rental vehicle for an extended period at significant personal cost totaling several thousand dollars. I'm a single parent with a child requiring ongoing medical appointments, making reliable transportation essential. Kia only approved a limited "goodwill payment" of $191.40 for an earlier rental period, while refusing reimbursement for the substantially larger rental costs incurred after the recall failure and progression to limp mode. When the vehicle entered limp mode, I had to arrange towing because Kia assistance was not available as they closed out the recall. Kia is now requiring out-of-pocket diagnostic payment before determining whether the issue is related to Recall 23V‑652, despite the warning condition returning immediately after recall repair and later progressing to limp mode consistent with the original failure symptoms. I am reporting a potentially ineffective recall remedy and unresolved recurrence of the safety condition addressed under Recall 23V‑652.

The contact owns a 2013 Kia Forte. The contact stated that while driving 45 MPH, the check engine warning light illuminated, and the vehicle went into LIMP Mode.

The failure reoccurred 2 days later. The contact received notification of the federal safety agency Campaign Number: 20V750000 (Engine); however, an unknown dealer attempted to charge the contact to replace the engine, even though the recall notification stated that the engine would be replaced as needed, free of charge. The manufacturer was made aware of the issue but declined the service request. No further information was available. The failure mileage was approximately 115,000.

Transmission was getting stuck in gear and slipping intermittently would cause the car to not accelerate over 20mph especially in the cold unless you switched it to the manual mode and manually shifted up two gears ans then back down two gears. If you looked at the tach while it did this is would bounce between 500 and 1500rpm and then would stutter and bounce between 1500 and 2500rpm until you did the manual gear trick. Eventually it started making a strange noise. I have serviced it on time and complained to Kia before about the issue which they stated they could not repeat so there was nothing they could do at that time and now when I took it back to Kia they stated its an internal trans issue and it now needs to be replaced but there was nothing they could do as it was now out of warranty. The car has less the 95k on it. I've had cars that had well over 400k on them in the past and still ran like new. The trans should not be failing already.

Car goes into limp mode or cuts power when trying to accelerate. Refuses to shift or will shift down and revs highers rpms then necessary, especially at any incline. Started around 70k miles and got worse when brought in for other recalls.
