NHTSA Complaint #11680536 — 2020 JEEP GLADIATOR

I am filing a safety complaint regarding repeated and unresolved transmission issues with my Jeep. The vehicle has undergone two full transmission replacements after a $10,000 repair, yet critical symptoms persist, including transmission overheating (up to 240°F) and a loud whining noise while accelerating. These problems continue despite no warning lights or diagnostic codes, creating a false sense of safety. On August 4, 2025, the vehicle reached 240°F and produced loud mechanical noise while driving. This mirrors the same symptoms from before the original transmission repair and represents a clear safety hazard. These issues put me at risk of sudden transmission failure, loss of power, or loss of control while driving. The dealer has confirmed the overheating and replaced the transmission twice, but the problem remains. A brake hookup was also installed incorrectly, causing additional safety concerns that were only corrected after my insistence. Despite multiple service visits, Jeep refuses to: Provide a loaner vehicle Escalate to a corporate-level inspection Offer a buyback or reimbursement Jeep offered only an extended warranty with a deductible, which I declined as inappropriate given the unresolved repair. I have also submitted a formal legal demand to Jeep, which remains unanswered. The lack of diagnostic codes paired with dangerous symptoms and unresolved failures is deeply concerning. This issue should be investigated for a potential defect in the transmission system or software diagnostics. I request that NHTSA investigate this matter and that Stellantis/Jeep be held accountable for unsafe practices and poor post-repair support.
