Top Problem #1: Blind Spot Warning System Malfunction
Multiple CX-70 owners have reported ongoing issues with the vehicle’s blind spot monitoring and collision avoidance systems. These problems include inaccurate warnings, steering resistance during lane changes, and inconsistent detection of surrounding vehicles.
Owners have described symptoms such as:
False blind spot alerts that activate when no vehicles are nearby, especially at highway speeds.
Unintended steering resistance during lane changes when the system incorrectly detects another vehicle.
Missed warnings when a vehicle is actually in the blind spot, increasing the risk of side-impact collisions.
Erratic “take over steering” alerts even when both hands are on the steering wheel.
For example, one CX-70 owner reported:
“Blind spot monitoring at highway speeds randomly triggers when nothing is there. Due to this, [the] car fights lane changes due to [the] collision avoidance system if you try to change lanes when it thinks something is there when it’s not.”
Top Problem #2: Transmission and Engine Jerking at Low Speeds
Numerous CX-70 owners report a jerky or sluggish response when accelerating from a stop or during low-speed driving. This problem negatively affects everyday driving, especially in stop-and-go traffic.
Reported symptoms from multiple consumers include:
Vehicle hesitates or lurches during takeoff
Noticeable rough shifting or gear engagement delays
Sluggish acceleration causing safety concerns in traffic
Occasional engine stall or loss of power during slow maneuvers
Take a look at what one owner said:
“When moving at a lower speed, 10-20 mph, the motor or transmission is jerky and sluggish. This makes it very slow to move when pulling out from red lights or when in stop and go traffic on the highway. (Might as well be pulling out from the light in an 18 Wheeler.) I haven’t taken it to the dealer because from my experience, unless there is a code to look up, it’s just money (and time) wasted.“
We understand the owner’s frustration, but you must take the vehicle to the dealership. You can read more on our Lemon Law Rights page.

Top Problem #3: Sudden and Unintended Acceleration
CX-70 owners have reported multiple instances of sudden acceleration at very low speeds. These incidents typically occur while parking, maneuvering in tight spaces, or pulling into a garage. Drivers report that the vehicle accelerates briefly on its own, creating a serious risk of collision.
Owners have described symptoms such as:
Unexpected engine revving between 1 and 5 mph without pressing the accelerator.
Sudden forward lurching that lasts for one to two seconds before stopping.
No warning lights or dashboard alerts appearing before or during the event.
Repetition of the issue with different drivers operating the same vehicle.
For example, one CX-70 owner stated:
“Twice now at very low speeds between 1-5 mph the engine revs up and the car lurches forward for a second or two. [I] was pulling into [the] house garage and was about to push [the] acceleration pedal when the engine revved on its own and jolted the car forward. I slammed on the brakes real quickly when it happened and slid to a stop almost a foot away from crashing into [the] house wall.”
What Should You Do If Your CX-70 Is a Lemon?
A lemon vehicle is one that suffers from substantial defects impairing its use, value, or safety, which remain unresolved after reasonable repair attempts. If your CX-70 exhibits repeated problems, you may qualify for protections under state lemon laws.
Start with these steps:
Document all repair visits, communications, and symptoms thoroughly
File a complaint with the National Highway Traffic Safety Administration (NHTSA) if applicable
Consult an attorney experienced with lemon law claims promptly to understand your options
If your vehicle continues to display unresolved problems despite repairs, you might be entitled to a refund, replacement, or cash settlement.
