Facts from the maker or a manual quote the page word for word; what real users report is summarised with a link to the page read. Recall status was checked directly with CPSC (United States), Health Canada: CPSC recall search returned no recall records for Uppababy / ALTA V2. Health Canada records mention Uppababy but only strollers, RumbleSeat adapters, bumper bars and a Peg Perego adapter; none applies to the Alta V2 booster. Official safety test results were looked up directly with CREP, the Child Restraint Evaluation Program, NHTSA's Car Seat Ease of Use Ratings, ADAC's child seat test: CREP, the Child Restraint Evaluation Program (Australia and New Zealand): CREP's published list of 216 tested seats is complete, and no brand or seat name contains Uppababy or Alta V2, so this booster has not been rated by CREP. NHTSA's Car Seat Ease of Use Ratings (United States): NHTSA rated the Uppababy Alta V2 booster model 1320-ALT-US-JKE, a different model number from the 1302-ALT-US listed here. It received 3/5 overall, 2/5 for securing the child, 2/5 for labels, 5/5 for vehicle installation features and 4/5 for instructions. These are ease-of-use ratings, not crash-test results. ADAC's child seat test (Germany, the UK and Europe): ADAC's published list since 2015 is complete and contains only Uppababy Mesa i-Size entries, not the Alta V2, so this booster has not been tested there in that period.
