Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Ground strap is faulty. I have owned the vehicle for less than 2 years and am already on my 4th battery because the ground strap keeps draining it. The dealership is finally replacing the ground strap under my warranty but on several occasions I have been left essentially stranded away from home because the vehicle was acting completely fine then will randomly not start due to the faulty ground strap not allowing the alternator to actually charge the battery. …”

“The gear shifter broke. The button on the back that you compress in order to trigger a button inside of the shifter, broke off and then the button inside got stuck. I was not able to shift gears and even though there was no other issue with the vehicle, I was stuck in a parking lot blocking other people's ability to move around me. It creates a safety hazard by not being able to shift gears to move the vehicle out of harm's way or even to be able to be towed in a safe manner. …”

“I am writing to formally request an investigation into a serious safety defect affecting my 2020 Alfa Romeo Stelvio . I believe this issue is part of a broader pattern of manufacturing and design flaws that have compromised both safety and reliability •My vehicle experienced a catastrophic engine failure, resulting in a total repair estimate of approximately $32,000. This failure occurred without prior warning signs and is highly unusual for a vehicle of this age and mileage. …”

“Upon starting the vehicle a number of warning lights illuminated including the battery light. Upon viewing the battery compartment the plastic enclosure surrounding the battery had a few inches of water inside. I do have videos showing the water inside the compartment and also video of water being vacuumed out of the compartment. We did some research and found that this exact same issue sparked a recall in the same model vehicle in 2018. Very dangerous and i hope this is not happening to others, based on our research it is.”

“The contact owns a 2020 Alfa Romeo Stelvio. The contact stated that while driving on two occasions at undisclosed speeds, the check engine, oil, and the Automatic START/STOP System Unavailable warning lights illuminated. The vehicle was taken to a dealer twice; however, on the first occasion, the failure was not duplicated. During the second visit, the contact was informed that the coolant was mixing into the engine oil, which caused the engine failure. The contact was informed that several unstated parts needed to be replaced. The vehicle was not repaired. …”
