With the exception of Australia, her chart success faltered thereafter, as proven with her 1975 hit "Your Mamma Won't Like Me", which proved to be a moderate success in the UK. Further singles "I Bit off More I Could Chew" and "I May Be Too Young", both failed to reach the UK Top 50. Quatro recorded an album in 1976 and released a new single in 1977 called "Tear Me Apart" which reached the UK Top 30, her first hit to have done so in three years. It would take another year for another big hit, this time with a change to a more mellow style giving Quatro a 1978 single "If You Can't Give Me Love" that became a hit there and in the United Kingdom. Later that year, "Stumblin' In", a duet with Chris Norman of the band Smokie, reached No. 4 in the US Both tracks were featured on the If You Knew Suzi... album. A year later, Quatro released Suzi ... and Other Four Letter Words, but none of her other work had much US success. This featured the hits "She's in Love with You", which made No. 11 in Britain, "Mama's Boy" (number 34), and "I've Never Been in Love" (number 56).
