Brand loyalty among US consumers for new vehicles dropped to a six-year low in June, according to new analysis from IHS Markit. Analysis of new vehicle registration data through June indicates that the overall brand loyalty rate of 51% in the US market is the lowest since August 2015.

This decline in loyalty is inevitably due, at least in part, to the major declines in dealer inventory stemming from the global microchip shortage, IHS Markit said.

Year over year, IHS Markit new vehicle registration data indicates that brand loyalty in the US fell by 1.7 percentage points (PP) to 51% in June (vs. June 2020). This follows a 2.5 PP drop year-over-year in May and a 2.8 PP decline in April.

The aggregated three-month brand loyalty in 2021 was 51.6%, down from 54% a year ago and 54.1% two years ago.

While consumers are changing brands, body style loyalty remains strong, increasing slightly. National overall body style loyalty rose 1.1 percentage points in June (year-over-year) to 55.5%.

The three dominant body styles—sedan, pickup, and sport utility—all experienced loyalty improvements, with sedan up 2.4 percentage points, pickup up half a percentage point, and SUVs up 0.3 percentage points. These three body styles accounted for 90% of all new vehicle retail transactions in the first six months of the year.

Households with a pickup in the garage like the concept of a pickup, and therefore will acquire another one. But their likelihood of staying loyal to the brand of their pickup has diminished.

The propensity of a household with a pickup in the garage to acquire another pickup has risen slightly to 50.8%, but the household’s loyalty to the brand of the pickup in the garage has dropped 3 PP to 53.3% in the past year. Again, it is likely inventory is playing a role, as the industry has encountered recent lows not experienced in quite some time.

These shifts indicate that there are both risks and opportunities for OEMs and their marketing teams in today’s new vehicle marketplace.
