2012 Toyota Camry vehicle speed control problems

“I am reporting a safety-related issue involving the ECM / torque converter on my 2012 Toyota Camry. This issue can cause loss of power, hesitation, or stalling which presents a serious safety concern while driving. The issue impacts drivability and can result in sudden loss of acceleration or engine stalling, especially at higher speeds or during merging. This creates an increased risk of collision for myself, passengers, and surrounding vehicles. I have experienced some scary occurrences with shuddering at high speeds, hesitation while near other innocent vehicles and stalling. I was never notified by Toyota about this recall or service campaign while it was active. I maintain current registration information and would have had the issue addressed immediately.

The vibration affects the transmission and drivability, particularly during city and highway acceleration, creating potential hazards when merging or navigating traffic. I believe this qualifies as a design flaw with potential safety implications. I respectfully request that NHTSA review Toyota’s handling of this issue and determine whether further consumer…”

“There was a recall on this Camry model 2012 to 2014 that the Charlotte, NC dealership refused to cover. I am having a transmission issue that causes my car to shudder and vibrate at regular speeds. “shudder comes from the transmission, especially during the acceleration of the Camry models. It can be alarming for the driver and be a safety concern when the gears do not properly change during operation. When this problem persists over a significant period of time, it has the poetry to cause long-term damage to your transmission. Damage to your transmission can be costly and affect the overall performance of your Toyota…” -Toyota of west county website”
